- Abstract
Hollows in mature trees provide a variety of habitats for high species richness and diversity of different arthropod groups. The scarcity of samplings carried out in tree hollows, especially on spiders and on mature oaks, predict the existence of taxonomic novelties in these rich microenvironments. A total of 18 Linyphiidae species, including one species new to science, were sampled with 49 tree hollow emergence traps set in deciduous Quercus forests in the Western Iberian Peninsula. Both sexes of Scotinotylus vettonicus Barrientos & Hernández-Corral sp. nov. and the female of the endemic Iberian Pelecopsis monsantensis Bosmans & Crespo, 2010 are described and both sexes of these two species and of Centromerus succinus (Simon, 1884) are illustrated. In addition, the spatial and temporal distribution of P. monsantensis, C. succinus, Midia midas (Simon, 1884) and Lepthyphantes minutus (Blackwall, 1833) is figured. Furthermore, the checklist of Linyphiidae species recorded in Salamanca province (Spain) is updated to a total of 40 species, representing 13% of all the linyphiids occurring in the Iberian Peninsula., Las oquedades en árboles maduros proporcionan una variedad de hábitats para una alta riqueza de especies y diversidad de diferentes grupos de artrópodos. La escasez de muestreos llevados a cabo en oquedades, especialmente sobre arañas y en robles maduros, hace prever la existencia de novedades taxonómicas en estos ricos microambientes. Un total de 18 especies de Linyphiidae, incluida una especie nueva para la ciencia, fueron colectadas utilizando 49 trampas de emergencia en oquedades de bosques caducifolios de Quercus en el Oeste de la Península Ibérica. Se describen ambos sexos de Scotinotylus vettonicus Barrientos & Hernández-Corral sp. nov. y la hembra del endemismo ibérico Pelecopsis monsantensis Bosmans & Crespo, 2010, y se ilustran ambos sexos de estas dos especies y de Centromerus succinus (Simon, 1884). Además, se representa la distribución espacial y temporal de P. monsantensis, C. succinus, Midia midas (Simon, 1884) y Lepthyphantes minutus (Blackwall, 1833). Además, se actualiza la lista de especies de Linyphiidae presentes en la provincia de Salamanca (España) a un total de 40 especies, lo que representa el 13% de todos los linífidos citados en la Peninsula Ibérica. more...

- Abstract
Agricultural landscape homogenization has detrimental effects on biodiversity and key ecosystem services. Increasing agricultural landscape heterogeneity by increasing seminatural cover can help to mitigate biodiversity loss. However, the amount of seminatural cover is generally low and difficult to increase in many intensively managed agricultural landscapes. We hypothesized that increasing the heterogeneity of the crop mosaic itself (hereafter “crop heterogeneity”) can also have positive effects on biodiversity. In 8 contrasting regions of Europe and North America, we selected 435 landscapes along independent gradients of crop diversity and mean field size. Within each landscape, we selected 3 sampling sites in 1, 2, or 3 crop types. We sampled 7 taxa (plants, bees, butterflies, hoverflies, carabids, spiders, and birds) and calculated a synthetic index of multitrophic diversity at the landscape level. Increasing crop heterogeneity was more beneficial for multitrophic diversity than increasing seminatural cover. For instance, the effect of decreasing mean field size from 5 to 2.8 ha was as strong as the effect of increasing seminatural cover from 0.5 to 11%. Decreasing mean field size benefited multitrophic diversity even in the absence of seminatural vegetation between fields. Increasing the number of crop types sampled had a positive effect on landscape-level multitrophic diversity. However, the effect of increasing crop diversity in the landscape surrounding fields sampled depended on the amount of seminatural cover. Our study provides large-scale, multitrophic, cross-regional evidence that increasing crop heterogeneity can be an effective way to increase biodiversity in agricultural landscapes without taking land out of agricultural production. more...

Description (male). Head. Frons brown, about as broad as long, with 113 hairs. Upper supra-antennal bristles about as long and strong as lower pair, and they are about as closer together as pre-ocellars, which are slightly lower on frons than mediolaterals and clearly closer together than either is from a mediolateral bristle. Upper supraantennal bristles at about the same level on frons as antials, which are lower on frons than anterolaterales, and about as far apart from these as from upper supra-antennal bristles. Gena with three long bristles and five shorter ones. Antennal postpedicel subglobose, brown and relatively small (diameter 0.10 mm), with SPS vesicles, each about diameter of basal socket of antial bristles. Palps dusky yellow, 0.10���0.17 mm long and 0.05 mm maximum width, with five bristles, the longest bristle being longer than greatest width of palp. Labella enlarged, yellow, with only a few short spinules below and a few long hairs. Labrum brown, about 0.85 �� as wide as an antennal postpedicel. Thorax. Brown. Mesopleuron bare. Three notopleural bristles and no cleft in front of these. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Propleura with 3���4 hairs on posterodorsal edge, 3���4 on posteroventral one and a few in middle, situated well forward of hindmargin. Abdomen. Tergites light brown, with scattered short hairs with those of the rear margin of T 6 only a little longer than the rest and about as long and strong as those on epandrium. Venter grey, with a few short hairs on segments 3���6. Hypopygium (Figs 1���2). Left side of epandrium light brown, without bristles, with hairs stronger than those on cerci, which are weaker than those on proctiger. Anal tube yellow, a little shorter than dorsal face of epandrium. Hypandrium, light brown, with both posterior lobes developed and with minute hairs below. Legs. Light brown, slightly clearing from the posterior to anterior legs, but without being yellowish. Front legs with a posterodorsal hair palisade on tarsal segments 1���4 and metatarsus a little enlarged. Length ratios of the fore tarsal segments 2.3: 1.3: 1.2: 0.9���1: 1, with fifth segment narrower than fourth one. Mid legs with a dorsal hair palisade on tibia extends about 2 / 3 of its length. Longest hairs below basal half of hind femur about as long as those of anteroventral row of outer third. Hind tibia with 15���18 differentiated posterodorsal hairs and spinules of apical combs simple. Wing. Length 1.70���1.76 mm.

In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 87, after return of 182, to M. conformis (Wood), but its hypopygium clearly differs from the new species, in the shape of epandrium and development of posterior lobe of hypandrium; the subsequently added M. lactipennis Lundbeck, runs to the same point; it differs from the new species clearly in the hypopygium (development of posterior lobes of hypandrium, shape of epandrium and thickness of hairs of epandrium and proctiger), in length of hairs of the rear margin of tergite 6, length of the hairs below basal half of hind femur and length of costal cilia (Disney, 2000). The subsequently described M. putescavi Disney runs to this couplet, but it is distinguised from the new species by having hairs on mesopleuron and a clearly different hypopygium, especially a larger left lobe of hypandrium (Disney & Withers, 2011). Material examined. Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31 TDG540279, 1250 m a.s.l., 19 / 05-02/06/ 1990. Window trap. J.A. Barrientos leg (UAB).

Upper supra-antennal bristles clearly longer (1.5 ��) and stronger than lower pair, and they are slightly closer together than pre-ocellars, which are at about the same level on frons than mediolaterals and about as far apart as either is from a mediolateral bristles. Upper supraantennal bristles clearly higher on frons than antials, which are a little lower on frons than anterolaterals, and closer to these than to upper supra-antennal bristles. Gena with three long bristles and four shorter ones. Antennal postpedicel subglobose, yellow and relatively small (diameter 0.10 mm), without SPS vesicles. Palps yellow 0.17 mm long and 0.05 mm maximum width, with eight bristles, the longest bristle being longer than greatest width of palp. Labella enlarged, yellow, without short spinules below, with only a few long hairs. Labrum yellow brown, about as wide as an antennal postpedicel. Thorax. Light brown. Mesopleuron bare. Three notopleural bristles and no cleft in front of these. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Propleura with three hairs on posterodorsal edge, four on posteroventral one and two in middle of the hind margin. Abdomen. Tergites light brown, with scattered short hairs on posterior half, with those of the rear margin only a little longer than the rest, gradually increasing in size from T 4 to T 6, with those of the latter a little shorter and as strong as those on cerci. Venter yellow, with a few short hairs on segments 3���6, increasing in number from the anterior to posterior segments. Hypopygium (Figs 3���4). Left side of epandrium yellow brown, without bristles, with hairs about as strong as those on cerci and proctiger; anal tube, yellow, about as long as dorsal face of epandrium; hypandrium yellow brown, with only posterior right lobe developed.

Upper supraantennal bristles clearly higher on frons than antials, which are lower on frons than anterolaterales, and closer to these than to upper supra-antennal bristles. Gena with three long bristles and four shorter ones. Antennal postpedicel subglobose, brown and relatively small (diameter 0.12 mm), without SPS vesicles. Palps dusky yellow, 0.21 mm long and 0.04 mm maximum width, with five long bristles and four very short ones, the longest bristle being longer than greatest width of palp.

Description (male). Head. Frons dark brown, about as broad as long, with 69���84 hairs. Upper supra-antennal bristles clearly longer and stronger than lower pair (one paratype has three pairs of supra-antennals), and they are slightly closer together than pre-ocellars, which are a little lower on frons than mediolaterals and, at most, about as closer together as either is from a mediolateral bristle. Upper supra-antennal bristles clearly higher on frons than antials, which are lower on frons than anterolaterales, and, at most, as far apart from these as from upper supraantennal bristles (two paratypes have a britsle in middle of anterolaterals and antials). Gena with 2���3 long bristles and 3���6 shorter ones. Antennal postpedicel subglobose, brown and relatively small (diameter 0,10���0,15 mm), without SPS vesicles. Palps light brown, inflated, 0.10���0.12 mm maximum width (about as wide as antennal postpedicel), with short hairs, 5���7 short bristles and a long one at tip, all bristles being shorter than greatest width of palp (Fig. 9). Labella enlarged, yellow, without short spinules below, with only a few long hairs. Labrum brown, about 0.7���0.8 �� as wide as an antennal postpedicel. Thorax. Brown or yellow brown. Mesopleuron with 11���30 hairs, bristles absent. Three notopleural bristles and no cleft in front of these. Scutellum with two pairs of almost equally bristles. Propleura with 2���5 hairs on posterodorsal edge, 3���4 on posteroventral one, and scattered hairs in middle and hind margin. Abdomen. Tergites brown, with numerous short hairs, longer at rear margins, especially on T 6 (0.11���0.13 mm long), which are longer and stronger than hairs on cerci and proctiger. Venter yellowish, with hairs on segments 3���6 gradually increasing in size from the anterior to posterior segments. Hypopygium (Figs 10���11). Left side of epandrium brown, with hairs, at most, as strong as those on cerci and proctiger. Anal tube yellow brown, yellow at the tip, about as long as dorsal face of epandrium. Hypandrium yellow brown, with both posterior lobes developed and with minute hairs below. Legs. Yellow to yellow brown, slightly darkening from the anterior to posterior legs. Front legs with a posterodorsal hair palisade on tarsal segments 1���5 and metatarsus a little enlarged and with longitudinal rows of short blunt spines on ventral face. Length ratios of fore tarsal segments 3���3.5: 1.5���2.6: 1.2���2: 1���1.2: 1, with fifth segment narrower than fourth one. Mid legs with a dorsal hair palisade on tibia extends about 80���85 % of its length. Longest hairs below basal half of hind femur, at most, a little longer than those of anteroventral row of outer third. Hind tibia with 12���16 differentiated posterodorsal hairs and spinules of apical combs simple. Wing. Length 1.80���2.64 mm. Membrane lightly tinged grey and veins light brown; with 5���8 axillary bristles. Subcosta (Sc) well developed, reaching R 1. With 1���2 hairs at base of vein Rs, 0.030���0.045 mm long. Costal index 0.51���0.55; costal ratios 2.7���3.3: 1.4���2.2: 1. Costal cilia (section 3) 0.10���0.13 mm long, shorter than longest axillary bristle (0.12���0.17 mm). Knob of haltere yellow, brownish at tip. Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 68, where neither option applies, although M. nigriceps (Loew) is close to new species, both with inflated palps with short bristles but they differ in the shape; they also differ in the hypopygium (especially in the shape of epandrium and length of anal tube) and by having, the new species, the hairs below basal half of femur shorter than M. nigriceps (Loew). The subsequently added M. funesta Schmitz runs to the same point; it differs from the new species in the hypopygium (shape of epandrium and length of anal tube), and in the shape of inflated palps (wider in the new species). The related species M. simulans (Wood) has a similar hypopygium to the new species, but the palps of M. simulans (Wood) are smaller and with longer bristles (Disney, 2011 b). The species M. specularis Schmitz, with a similar hypopygium to the new species, it differs in shape of epandrium and palps (Disney & Durska, 2011). In the keys of Palaearctic Phoridae (Schmitz et al, 1938 ��� 81) this species runs to couplet 22 (Abteilung I, page 407), to M. projecta (Becker), synonym of M. nigriceps (Loew). Material examined.

Antials bristles lower on frons than anterolaterals, but no situated nearly directly below these; longest bristle on palp clearly longer than maximum width of palp; mesopleuron bare; notopleuron with two bristles; scutellum with a posterior pair of bristles and an anterior pair of hairs; venter with a few short hairs on segment 3���6; left side of epandrium with hairs which are more robust than hairs of cerci, but a little shorter than those at rear margin of sixth abdominal tergite; anal tube about as long as dorsal face of epandrium; terminal hairs of proctiger as robust as strongest hairs on cerci; legs yellow brown; fore metatarsus not slender; know of haltere brown; with one short hair present at base of vein Rs; subcostal vein (Sc) not reaching R 1; costal cilia (section 3) as long and strong as longest axillary bristle; costal index clearly less than 0.5. Description (male). Head. Frons longer than broad, with 67 hairs. Upper supra-antennal bristles longer and stronger than lower pair and they are slightly closer together than pre-ocellars, which are at about the same level on frons than mediolaterals and as far apart as either is from a mediolateral bristle. Upper supra-antennals slightly higher than antials, which are lower on frons than anterolateral bristles, and a little closer to these than to upper supra-antennal bristles. Gena with two long bristles and four shorter ones. Antennal postpedicel subglobose, brown and relatively small (diameter 0.11 mm), without SPS vesicles. Palps dusky yellow, 0.21 mm long and 0.075 mm maximum width, with seven bristles, the longest bristle being longer than greatest width of palp. Labella enlarged, yellow, with only a few short spinules below and a few long hairs. Labrum brown, about 0.9 �� as wide as an antennal postpedicel. Thorax. Brown. Mesopleuron bare. Two notopleural bristles and no cleft in front of these. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Propleura with three hairs on posterodorsal edge and four on posteroventral one. Abdomen. Tergites brown, with scattered short hairs, progressively longer from fourth to sixth terguite, with those of the rear margin of T 6 a little longer than longest hairs of epandrium, but about the same thickness. Venter grey, with a few short hairs on segments 3���6, gradually increasing in size from anterior to posterior segments. Hypopygium (Figs 7���8). Left side of epandrium brown, without bristles, with some hairs stronger than those on cerci, which are as strong as those on proctiger. Anal tube yellow brown, about as long as dorsal face of epandrium. Hypandrium, yellow brown, with both posterior lobes developed and with minute hairs below. Legs. Mainly yellow brown, slightly clearing from posterior to anterior legs, with fore tarse and tibia yellowish. Front legs with a posterodorsal hair palisade on tarsal segments 1���4 and metatarsus not enlarged.
