Loretoniscus Ocampo-Maceda, López-Orozco & Campos-Filho gen. nov. urn:lsid:zoobank.org:act: 293A9B09-3480-4B20-807B-64C27672ACD0 Type species Loretoniscus mashiriaensis gen. et sp. nov., by present designation and monotypy. Diagnosis Body convex. Animals with partial conglobation ability; exoantennal conglobation. Cephalon with welldeveloped antennary lobes, triangular frontal shield slightly developed, laterally interrupted by antennal grooves, frontal line delimiting frontal shield on upper portion. Pereonite 1 epimera without dorsolateral furrows and schisma. Pereonites 1–3 without ventral lobes. Pleon outline continuous with that of pereon. Telson triangular with distal portion covering uropod endopods. Antennula with three articles. Antenna with flagellum of three articles, second and third articles divided by thin suture. Mandible with molar penicil dichotomized. Maxillula outer endite with outer group bearing teeth cleft at apex. Uropod protopod subrectangular, exopod inserted distally. Pleopod exopods 1 and 2 with respiratory areas. Etymology The new genus is named after the department where the specimens were collected: Loreto. Remarks In the complex shape of the depressions in the frontal shield of the cephalon, and the absence of dorsolateral furrow on pereonite 1 epimera, Loretoniscus gen. nov. resembles Iansaoniscus; however, it differs in the broad shape of the telson with lateral margins straight (vs concave), uropod protopod subrectangular (vs subquadrangular), and pleopod 1 and 2 exopods with respiratory areas (vs absent). The Pudeoniscidae were recently revised by Campos-Filho et al. (2018b). The diagnostic characters of the family do not comprise the variation observed in Iansaoniscus and Loretoniscus gen. nov. Thus, the diagnosis of the family after Campos-Filho et al. (2018b) is emended as follows: animals with exoantennal conglobation; cephalon with triangular frontal shield and profons having complex depressions, and pereonite 1 epimera with dorsolateral furrow to fit antennae during conglobation (reduced or absent in cave-dwellers or endogean species); epimera of pereonites 1–3 with small ventral lobes or schisma on pereonite 1 (reduced or absent in cave-dwellers or endogean species); pleon outline continuous to that of pereonite 7, neopleurae 3–5 well developed and rectangular, telson triangular or trapezoidal with proximal portion wider than distal portion; antennal flagellum of three articles, second and third divided by suture; uropod protopod subquadrangular, exopod inserted distally, endopod not surpassing the distal margin of telson; and pleopod exopods with respiratory structures. Loretoniscus gen. nov. is included in the family Pudeoniscidae by sharing most of these mentioned characters. The absence of dorso-lateral furrow and schisma on pereonite 1 epimera, and absence of ventral lobes on pereonites 1–3 epimera are closely related with the conglobation ability, an ecomorphological strategy of oniscideans used against predation and to reduce water loss (Edney 1951; Schmalfuss 1984). The new genus includes one new species with endogean habits, and probably the absence of these structures is related with habitat selection.

Pereopod 7 (Fig. 17B) without any sexual dimorphism. GENITAL PAPILLA. Ventral shield ovoid, papilla bifurcate with genital orifices opening at apex (Fig. 17C). PLEOPODS. Pleopod 1 (Fig. 17D) exopod triangular, inner margin almost straight, outer margin sinuous, distal portion triangular with distal margin rounded; endopod with thickest distal part with sides almost parallel, inner distal part with long pointed process concave on outer margin, prominent subquadrangular apical lobe on outer distal portion bearing thin setae. Pleopod 2 (Fig. 17E) exopod triangular, outer margin concave, bearing seven stout setae; endopod robust, distinctly longer than exopod. Exopods of pleopods 3–5 as in Fig. 17F–H. Remarks Vandel (1973) erected the genus Microphiloscia to allocate the new species M. trichoniscoides from Cueva de la Colorada, Provincia de Oriente, Sierra Maestra, Colorada del Maso, Cuba. After the examination of material belonging to this species, M. trichoniscoides shows the shape of the genital papilla and male pleopod 1 endopod typical of members of Halophiloscia (see also Taiti & Lopez 2008). Halophiloscia includes 9 halophilic species mainly distributed along the Mediterranean and Atlantic coasts of Europe and Africa (Schmalfuss 2003; Taiti & Lopez 2008; Taiti & Argano 2009, 2011). In America, only H. couchii (Kinahan, 1858) was recorded, from Argentina, Bermuda, and USA (see Schmidt 2003). The genus is mainly characterized by the runner-type habitus (sensu Schmalfuss 1984), epimera of pereonites 1–7 with one or more lines of noduli laterales, male pereopod 1 and sometimes pereopod 2 carpus and propodus enlarged and covered with several scales on frontal side, male genital papilla distally bifurcated, and male pleopod 1 endopod stout bearing a long, pointed process on the apex (see Schmidt 2003; Taiti & Lopez 2008). The species is included within the genus since it shows all the previously mentioned characters, except that the male pereopods 1 and 2 do not have the carpus and propodus enlarged. Thus, Microphiloscia is considered to be a junior synonym of Halophiloscia. Distribution Cuba (Vandel 1973). First record for Colombia.

For a definition of the genus see Arcangeli (1957), Vandel (1962), Taiti & Ferrara (1989), and Schmidt (2002). Armadilloniscus luisi Carpio-Díaz, Taiti & Campos-Filho sp. nov. is readily distinguished from all the other species of the genus in the number and arrangement of the dorsal tubercles on the cephalon, pereon and pleon. Moreover, it can be distinguished from the other four Caribbean species in having two broad tubercles on pleonite 2 (vs small in A. caraibicus and A. steptus, absent in A. ninae), the cephalon with the median lobe triangular (vs rounded in A. caraibicus) and lateral lobes subquadrangular (vs subtriangular in A. ninae and A. steptus), eyes composed of four ommatidia (vs 4–5 in A. caraibicus, 6 in A. ellipticus and 5 in A. ninae), telson with distal margin truncate (vs rounded in A. caraibicus and A. ellipticus, triangular in A. ninae), and ♂ pleopod 1 exopod ovoid (vs subtriangular in A. caraibicus, A. ellipticus and A. ninae, almost rounded in A. steptus) (Paoletti & Stinner 1989; Schultz 1984; Schotte & Heard 1991; Garthwaite et al. 1992; Schmidt 2002). Distribution Presently known only from Isla Grande, Cartagena de Indias, Colombia.
