Description of Lasiobelba (Antennoppia) nepalica sp. n. Figs 10-15

Diagnosis.

Body size: 996-1278 × 697-830. Prodorsal setae long, barbed; ss ≈ in> le> ex> ro. Nine pairs of notogastral setae long, barbed (p1-p3 shorter than others). Antero-medial part of rutelli with tooth. Anogenital setae barbed. Dorsal side of leg claws with small teeth.

Description.

Measurements. Body length: 1195 (holotype, male), 996-1278 (three paratypes: two males and one female); notogaster width: 730 (holotype), 697-830 (three paratypes).

Integument (Figs 10, 12). Body color light brownish. Body surface smooth, but lateral parts of prodorsum with microgranulate cerotegument (diameter granules up to 1).

Prodorsum (Figs 10, 12). Rostrum widely or narrowly rounded. A row, comprising several muscle sigillae, is located in front of the bothridia. One pair of muscle sigilla in interbothridial region poorly visible. Rostral (143-164), lamellar (254-287), interlamellar (307-348), exobothridial (205-258) and bothridial (307-348) setae well developed, setiform, barbed. A pair of triangular tubercles located posteriorly to bothridia.

Notogaster (Figs 10-12). Anterior border convex. Notogastral setae c and their alveoli reduced. Nine pairs of notogastral setae long, barbed; p1-p3 (184-192) shorter than h1, h2 (265-332) and others (398-464). Lyrifissures ia, im and opisthonotal gland openings (gla) poorly visible; lyrifissures ip, ih, ips present, but visible under high magnification in dissected specimens.

Gnathosoma (Figs 12, 13). Subcapitulum longer than wide (266 × 199-209). Antero-medial part of rutelli with tooth (8-10). Subcapitular setae setiform, barbed; a (61-65) shorter than m and h (both 98-102). Two pairs of adoral setae (41-45) setiform, indistinctly smooth. Palps (196) with setation 0 –2–1–3– 8(+ω). Solenidion thickened, blunt-ended, pressed to the palptarsus surface in basal part and distal seta in distal part. Chelicerae (266) with two barbed setae; cha (86) longer than chb (53). One short tooth (4-6) located posteriorly to seta cha. Trägårdh’s organ distinct.

Epimeral and lateral podosomal regions (Figs 10-12). Apodemes (1, 2, sejugal, 4) weakly developed. Epimeral setae setiform, barbed; setae 1a, 2a, 3a (69-86) shorter than 1b, 1c, 3b, 4a, 4b (114-127), 3c (205-209) and 4c (155-164). Pedotecta I normally developed, scale-like. Discidia triangular, pointed.

Anogenital region (Figs 11, 14, 15). Five pairs of genital setae (g1-g3, 41-53; g4, 61-69, g5, 73-82) setiform, indistinctly barbed. One pair of aggenital (123-135), three pairs of adanal (159-172) and two pairs of anal (114-123) setae setiform, barbed. Distance between setae ad3-ad3 longer than ad2-ad2 and ad1-ad1. Adanal lyrifissures iad located longitudinally.

Legs. Generally, similar to Lasiobelba (Lasiobelba) daamsae sp. n. (see also Table 1).

Type deposition.

The holotype and one paratype are deposited in the collection of the Senckenberg Institution Frankfurt, Germany; two paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.

Etymology.

The specific name “nepalica” refers to the country origin, Nepal.

Remarks.

In having the long prodorsal and notogastral setae and large body size, Lasiobelba (Antennoppia) nepalica sp. n. is most similar to Lasiobelba (Antennoppia) granulata (Mahunka, 1986) from Tanzania. However, it clearly differs from the latter by the larger body size (996-1278 × 697-830 versus 820-861 × 541-574 in Lasiobelba (Antennoppia) granulata ), exobothridial setae longer than rostral setae (versus rostral longer in Lasiobelba (Antennoppia) granulata ) and bothridial setae not longer than interlamellar setae (versus clearly longer in Lasiobelba (Antennoppia) granulata ).
