Paulson, D. R. (Department of Zoology, University of Washington, Seattle, Washington 98195) 1974. Reproductive Isolation in Damselflies. Syst. Zool. 23:40-49.-Experiments were performed in the field on males of five species and females of ten species of damselflies (Odonata: Zygoptera: Coenagrionidae) to determine the relative importance of visual and mechanical reproductive isolating mechanisms. Males of all five species did not distinguish visually their own female from heterospecific females of the same genus, but they were slightly less responsive to females of other genera, probably because of size differences. When the males attempted to mate with females of other species, they were usually prevented from doing so because their abdominal appendages were unable to secure a firm grip on the appropriate thoracic structures in the females. In only one species pair was the male able to achieve the tandem position successfully most of the time, and the reciprocal was unable to do so. Mechanical isolation is clearly very important in this group of odonates, and it is hypothesized that it will be found to be important in all odonates in which male appendages differ substantially between species while female coloration does not. [Reproductive isolation; damselflies.] Recent discussions of reproductive isolation in animals (Littlejohn, 1969; Mayr, 1970; Dobzhansky, 1970; Stebbins, 1971) emphasize that there is very little evidence for the operation in nature of the phenomenon of mechanical isolation, in which the genitalia of a male of one species fail to fit with the genitalia of a female of another species, thus preventing mating. Mayr (1963, 1970) cited a study by Webb (1947) of polygyrid snails as perhaps the only good example of interspecific mating being prevented by the structure of the genitalia. That paper is not convincing, the most positive evidence of mechanical isolation being "observations wherein the mating has been noted to be obstructed by out-of-timing malfunctioning. In one case, persistently-faster-eversion prevented a common entwistment of the penis with that of the prospective mate" (Webb, 1947:137). This apparently was an attempted mating between individuals of the same species, and Webb went on to say that he had never observed attempts at "interspecific sementransfer by any of the polygyrin species studied." In the related subfamily Triodopsinae cross-copulation between different species was observed, and in some of these species it was successful. Webb did not write that he observed individuals of different species attempting copulation but being prevented from copulating by the structure of their genitalia, and his paper is not evidence of mechanical isolation in animals. Mayr (1963) further cited two lines of evidence from a number of taxa against the existence of mechanical isolation: (1) species with different genitalia can interbreed; and (2) altering the male genitalia fails to prevent successful copulation and fertilization. Thus he concluded that "mechanical isolation plays a very minor role as an isolating mechanism in most groups of animals" (1963: 104). In fact, Mayr (1970) attempted to explain the differences among the genitalia of related species as incidental changes, the pleiotropic by-products of many changes in the genetic constitution of the species. He hypothesized that as long as any sort of apparatus could function during clasping and copulation, then variations would not be subject to selection. Dobzhansky went further in stating that the "usefulness of genitalia for distinguishing species does not necessarily mean that they are important in mechanical isolation. The reason for their usefulness is that the complexity of genitalic structures is often so great that species differences are more likely to be manifested in these structures than in

Tillyard (192G, p. 80, footnote) discussed the proper names for the groups (genus, family, etc.) of dragonflies based, eventually, upon Libellula virgo Linnaeus and L. puella L.: “It is unfortunate that the fine classical name Calopteryx, which was in general use unchallenged for three-quarters of a century has to be discarded by the Law of Priority, the type of the Linnean genus Agrion being the insect which had been known for all that time as Calopteryx virgo L. The new name required for the genus whose type had been known as Agrion puella L., was supplied by Kirby, viz.: Coenagrion, who also changed the family to Coenagrionidae, by analogy with the old form Agrionidae. The name Agrion, however, is derived from Greek agrias, wild, neuter Agrion, a wild thing, stem agri -, and hence the correct family names are Agriidae, Coenagriidae, Megapodagriidae, and the superfamily names Agrioidea and Coenagrioidea.”

The paper describes and maps stripe pattern variability in the damselfly Argia apicalis (Say) along the periphery of its southeastern distribution. Two major variations exist. One, the broad-striped form, has a wide, full-length humeral stripe and, in females, a well-developed middorsal thoracic stripe. Broad-striped specimens also possess larger areas of black pattern on the dorsum of the head and, in males, on the eighth and ninth abdominal segments. The second, typical form, has a reduced pattern characterizing populations west and north of southeast Georgia and northern Florida. The southeastern margin of distribution consists of broad-striped populations representing four groups of isolated populations. Isolation results from low interchange between colonies of different river systems and, within the southeast, lack of colonies on lakes, ponds, smaller streams, and river headwaters. One intergradation area between typical and broad-striped populations is known. A discussion follows relating origin of the variability to Pleistocene habitat changes.

The following descriptions are of material collected by William Clarke-MacIntyre on the head-waters of Tributaries to the Amazon in the Province of Oriente, Ecuador. They are from the edge of the Amazonian jungle on the lower eastern slope of the Andes Mountains, a tropical region of swift streams lying 400-8OO meters above sea-level. The types are in the author's collection.

Summary During the summer 1963/64, numerous excursions were made to two ponds at the Isla Teja (Valdivia, Southern Chile) and the Odonate fauna was studied. 9 of the 38 species known from Chile (Fraser 1957) were found in their immediate vicinity. Two further species from other biotopes in the environment of Valdivia are also mentioned. They are described and biological data concerning season of flight, abundance, ovi‐position etc, are given for most of the species, especially for Acanthagrion interruptum Selys (Zygoptera, Coenagrionidae).

The chromosome number in the damselflyEnallagma cyathigerum (Charp.) is 2n ♂=27, 2n ♀=28, n ♂=14 (13). The sex determining mechanism is XX-XO, the X segregates postreductionally in the male.

This species has not revealed itself since the time of its description. I am much indebted to Herr Dr. A. Kastner, of the Naturkundemuseum, Stettin, for the loan of Kruger's types of gracilis, which I have thoroughly compared with our fine series of specimens and found them well agreeing. The type ♂ from Soekaranda is lost and the authorities of the Stettin Museum were unable to trace it, but fortunately the description of the male is very detailed and the agreement with the Palembang specimens is so close that 1 have no hesitation in referring them to Kruger's species, M. A. LIEFTINCK: Descriptions and records 0 ƒ S. E. Asiatic Odonala. 373 Female (ad). — The adult specimens that I take to be the ♀ of this species are identical with Kruger's example. I have made Kruger's “ mittelreifes ♀ " the allotype of gracilis; the colours of the thorax of this specimen are faded and the various black spots and stripes mentioned in Kruger's description are very obviously due to postmortem decomposition. In our series of females no two examples are exactly alike, the colouring of the dorsal surface varying from cinnamon- or olive-brown to ‘ medal-bronze’ (Ridgway), whilst the sides are dark bluish glaucous (OP greenish glaucous-blue) in matured specimens. Several females show the same thoracic colour-pattern as Kruger's examples; but there are no real antehumeral stripes, and the black spots or stripes are merely apparent. The ante-alar triangles are metallic-green, and the under surfaces pale yellow. Legs, including the coxae, yellow; femora and anterior tibiae striped with black exteriorly, knees and apices of tarsal joints also black. The abdomen is coloured similarly to wallacei and annae. Female (juv.). - The type of Kruger's red colour-phase lacks its head and prothorax, as well as the terminal abdominal segments. Our specimens agree with the description in all respects, except that the prothorax is entirely red.

Male. — These specimens agree exactly with Ris’s account of A. martini, save that in the fully adult examples the colour of the pterostigmata of the fore wings is deep greenish-black centred with dark brown and with the border yellow, whilst those of the hinder wings are throughout bright orange. There are 14-15/13 postnodal cross-nerves. In the semi-adult males the thoracic sides and legs are yellow. The colour of the tenth abdominal segment varies from yellow to pale blue. Anal appendages wax-yellow to pale brown. Superior pair decidedly shorter than in wallacei and allied species, each with a distinct triangular protuberance at about the middle of their length, directed obliquely inwards and upwards, followed by a similar (slightly more robust) triangular expansion, which projects horizontally inwards; the median incision between these two projections (Ris, loc. cit. fig. 6) is visible only in oblique dorsal view. Inferior pair of appendages only half a long as the superiors, cylindrical, tapering, slightly divergent, tips evenly and but slightly upcurved. 376 TREUBIA Deel 17, 1940, AFL. 4.

Female (juv.). - The red colour-phase of this species is peculiar for the brilliant metallic-green episterna of the mesothorax, which, in the red-bodied females of other species, are of the same colour as the rest of the thorax. There is also a median bronze-green spot on the middle of the prothorax that covers the whole of the posterior lobe as well.

Holotype in the Buitenzorg Museum. Male (ad.). — Labium salmon-buff. The whole anterior surface of the head, as far upwards as the frontal ridge and including the basal two joints of antennae, bright orange. Tips of mandibles black. Frontal ridge sharply pronounced, rectangulate. Dorsal surface of frons, vertex and epicranium ochraceousorange, the postocular lobes fading to Buckthorn brown. Lateral extremities of epicranial furrow very finely lined with black. Rear of the head pale greenish-yellow. Prothorax and dorsum of synthorax, as far down as the humeral suture, light ochraceous-tawny; sutures and ridges of prothorax dark brown; posterior lobe of same simply rounded. Only the lower (mesostigmal) ridges of mesepisternites lined with black posteriorly. No black lines along either side of the mid-dorsal carina, nor on the humeral sutures and alar ridges. Dorsal impressions of the humeral and second lateral sutures with a minute black line. Thoracic sides ochraceous-tawny, slightly intermingled with green. Infraepisterna and lower end of metepimeron yellow ocher. Under surfaces pale greenish-yellow. Legs ochraceous-buff, apices of tarsal joints and claws black, as are also the spines. Wings light amber, extreme apices smoky. Pterostigma greyish-brown, much longer than high, oblique and parallel-sided. Ab arises at level of Ac in all wings. Postnodals 1312/11.11. Abdomen grenadine-red, the sides of first and second segments paler. Segm. 6 with a very fine, sharply defined, black apical ring, restricted to the dorsum. Posterior five-sevenths of the dorsum of 7, and the whole of that of 8 - 10, deep shining black, except for a pair of minute reddish dorsal points, on either side of the middle line, near the apex of 7. Sides of 7 - 8 and 10 pale reddish, those of 9 black. Sternites light red, paling to yellowish posteriorly. Intersegmental membranes between 7 - 1 0 finely yellowish. Posterior margin of segm. 1 0 pinched and strongly excavated, showing a rounded, Λ -shaped ridge which is minutely denticulated. Anal appendages much shorter than segm. 10, superiors entirely black, inferiors yellow basally. Superior pair globular, rather twisted and with a small, curved interior sub-apical projection. Inferior pair distinctly longer than the superiors, with inflated bases, tapering, distal third more abruptly narrowing and inclined a little inwards and strongly upwards (fig. 14). Length: abd. + app. 27.5, hw. 20 mm. Female unknown. M. A. Lieftinck: Descriptions and records of S.E. Asiatic Odonata. 361 This interesting new species differs from its congeners, and especially from other red-bodied species, such as C. erubescens, Selys, by the deep black terminal segments of the abdomen. The anal appendages are rather similar to those of erubescens, but the superiors arc black, and there is only one very small interior tooth. C. hoogerwerfi seems to be most nearly allied to bellona, Laidlaw 1), from Mt. Matang, Sarawak, and Mt. Kinabalu (Borneo). It differs from that species in the longer petiole of the wings, Ab in the wings of bellona originating well before the level of the cubito-anal cross-vein, whereas in hoogerwerfi the two veins are coincident, the position of Ac distal to Ax1 being identical in the two species. C. hoogerwerfi differs further from bellona in the sharply defined, deep black upperside of segments 8 - 1 0 of the abdomen, the distal five-seventh of 7 being also black in colour, whereas in bellona the apical segments are gradually and indefinitely obscured. The anal appendages of the two species are very similar, but the inferior pair of bellona are decidedly longer than those of hoogerwerfi. I have compared the type of this new species with two males and two females of topotypical bellona in my own collection and in that of the Michigan Museum, Ann Arbor, from Mt. Kinabalu. C. hoogerwerfi, I think, is also remotely allied to pendleburyi, Laidlaw 2), from the hill-country of Perak. It is easily distinguished from that species by its orange face, the absence of black lines on the dorsum of the thorax, and by the bright orangered abdomen. It differs further from pendleburyi in the basal portion of the 7th abdominal segment being red instead of black, in the absence of brown basal annules to the base of 7 -10, and in the short and rounded superior anal appendages, which in pendleburyi taper toward the apex, being equal in length to the inferior pair.

A fine series of specimens was obtained by Mr. COOMANS from the marshy forests of West Borneo, and these agree in all essential characters with LAIDLAW'S description and sketches of A. louisae. A recent examination of the type of A. wallacei, in the Brussels Museum, has brought to light that louisae is the same species as wallacei, and that the supposed examples of wallacei recorded by Ris and Laidlaw in reality belong to a species previously unknown to science, for which I proposed the name annae, and of which a description is given above. Selys's type specimen, collected by WALLACE, though still in excellent condition, is not quite matured; the anal appendages and the prot-horacic spine are exactly identical in structure with those of our series, but the legs are missing. 372 'Pastels Dene 17, 1940, Aim. 4. There are 12 postnodal cross-veins in both fore wings, 11 in the hinder pair. I can find nothing to distinguish our specimens from the type, except that the nodal index varies from 11-13/10-12. Apart from the well-marked differences in the shape and armature of the anal appendages, wallacei is easily distinguished from annae by the much shorter prothoracic spine, the sharply defined black lines along the posterior surfaces of all femora, and by the complete yellow stripe in front of frons, which is not (or only narrowly) interrupted by black in the median line. Female. -— Young individuals of this sex are as vividly coloured as those of annae, but the possession of a shorter spine on the prothoracic hind lobe will serve to their easy recognition. The adult ♀ may be briefly described as follows:- Head coloured much as in the red form; mandible-bases with a diffuse brownish central spot, basal three-fifths of labrum shining black. Pale fascia in front of frons entire, scarcely constricted on middle. Dorsal surface of head dark metallic bluish-green, or almost lustreless. Pro- and synthorax dull greyish- to greenish-brown dorsally, growing paler laterally; sides in fully matured examples usually glaucous-green, under surfaces much paler. Ante-alar triangles metallic-green. Legs, including the coxae, cream-buff; all femora definitely striped with black exteriorly and with the knees also deep black. Spines and extremities of tarsal joints black. Abdomen with segments 1 and 2 lustrous brown above, each with a terminal metallic-green ring. The rest of the abdomen greyish-brown, pale yellowish below, progressively darker posteriorly, the apical segments (with the exception of 10) being dark brown. Dorsum of 9 with two roundish, pale, sub-apical spots, 10 and appendages entirely greenish-white. Valves also pale-coloured, barely surpassing the anal appendages., Published as part of M. A.

(louisae smedleyi). Material studied: - 2 ♂ (ad, crushed), 2 ♀ (one ad., one juv.), Siberoet Id., Sept. 1924, C. Boden KLOSS & N. SMEDLEY, ex coll. F. F. LAIDLAW. These specimens differ from wallacei (= louisae LAID.) in a number of characters, which I have enumerated in the key to the species. The ♂ is easily distinguished from wallacei by the different shape of the superior anal appendages and by the absence of a prothoracic spine. The ♀ has been described at length by Ris. This species is obviously most closely related to gracilis, KRUGER, and kuiperi, LIEFT., two species in which the prothoracic spine is either also reduced, or absent altogether. Apart from the differences found in the sculpturing of the hinder lobe of the prothorax, the ♂ of smedleyi may be distinguished from that of kuiperi by the presence of a black streak to the outer surface of all femora; it differs further from kuiperi in the shape of the superior anal appendages, which bear a very close resemblance to those of gracilis, being in fact practically identical with those of that species (pl. 16 fig. 2). On comparing smedleyi with gracilis, these species proved to resemble each other very closely, and I could find no other distinctive features than those mentioned already in the key to the species. Granting the characters of the prothorax to be constant, there should be no difficulty in separating them; but it is doubtful if these differences are of specific significance. In view of the rarity of these extremely delicate species in collections, it seems worth recording the observed differences even on the small series available. Personally I am of opinion that smedleyi is only a subspecies of the Sumatran gracilis, KRUGER., Published as part of M. A.

The following emendations are necessary to complete the original description of the male and the characters mentioned in the key. Occiput with a yellow stripe behind the transverse carina. Prothorax in side-view with the upper half brilliant metallic-green, the lower half pale pearly green, under surface pale yellow. Anterior lobe yellow, its free margin finely bordered with black. Lateral divisions of posterior lobe wanting, side-angles rounded in profile view. Synthorax, as far down as half-way between humeral and first lateral suture, brilliant metallic-green. A squarish spot of the same colour occupies the upper (anterior) half of the mesinfraepisternites, succeeded posteriorly by a short yellow stripe along the mcsepimeral suture. Metallic green spot on upper part of metepisternuin roundish and almost isolated. Coxae pale yellow; femora entirely orange, tibiae and tarsi yellow. Pterostigmata of fore wings dark grey with pale orange margin and with the border orange-brown; those of the hinder pair (including the border) bright orange, darker in the centre. In the slightly younger male the pt of the hinder pair of wings differs but slightly in colour from those of the fore wings. The anal appendages vary in colour from almost pure white to dirty yellowish, with pink-coloured apices. Female (ad., allotype, androchromatic). — Differs from the ♂ only in the ground-colour of the thorax being less vividly yellow, whilst the femora are pale orange. Spine of prothoracic hind lobe directed straight upwards, amply half as long as that of the male, being in fact about equally long as the mid-lobe of the prothorax, bronze-green in colour, its distal half dirty yellowish.

Asiatic Odonata. 377 Pterostigmata of fore wings dark greyish-brown, with narrow pale margin, their border brown; those of hinder Wings with the yellow' margin broader, especially along costal border, which itself is pale brown in colour, Abdomen coloured as in the opposite sex, intermediate segments pale brown above, 3 - 6 with distinct basal yellow rings, interrupted mid-dorsallv Terminal segments darker brown with purplish reflections above, lacking definite pale spots. Anal appendages orangish. Valves brown, barely surpassing apex of abdomen. The extreme delicacy of this rare species is worth mentioning. In the shape of the anal appendages and in the colour of the pterostigma of the ♂, madelenae comes nearest to martini, from which it differs (among other characters) by the absence of a prothoracic spine in both sexes., Published as part of M.

The classification of the COENAGRIIDAE is by no means easy, owing to the paucity of morphological characters, and as our knowledge of the family progresses the boundaries of many genera are becoming less clear; the whole family is in need of considerable revision which will take into account more and newer characters (asyet undetected) than the few which are a t present used., Published as part of Cowley, J., 1940, A list of the Odonata of the islands of the western Mediterranean area., pp. 172-178 in Proceedings of the Royal Entomological Society of London 9 on page 173, DOI: 10.5281/zenodo.3525044

Agrion lindeni Selys. Lake Huleh, ♀, 24.v.22. Through its small size (h.-w. 16 mm.), slightly immature condition and Ischnura-like neuration, this specimen puzzled me so much that eventually I submitted it to Dr. Ris, who determined it as A. lindeni. No doubt he is right, the posterior margin of prothorax, mesostigmal lamina, pterostigma and markings agreeing almost perfectly with that species. The neuration (M, only 4 cells in f.-w., and 3 in h.-w., distal from nodus) may be regarded as consistent with the reduced size of the insect. Recorded by Selys (after Hagen) from Kellemisch in Rev. Odon., 1850, and Synops. Agrionines, 1876, but for some unexplained reason omitted from his paper of 1887. The locality, Asia Minor, is, however, retained in Cat. Kirby.
