description: MITRAGER ASSUETA (TANASEVITCH, 1998) COMB. NOV.
(FIGS 38R, 39R, 40S, 42, 43B; SUPPORTING INFORMATION, FIG. S4E)
Oedothorax assuetus Tanasevitch, 1998a: 431, figs 1–5 (Dm).
Type material: Holotype: Nepal: Kathmandu, Godawari, foot of Phulchoki Mt., 1700 m, ♂ 19.iii.1980, leg. Martens & A. Ausobsky (SMF 38848, examined). Paratypes: Nepal: same locality, together with holotype, 1♂, leg. J. Martens & A. Ausobsky (body: SMF 38852, palp: SMF 38841, examined).
Diagnosis:
Males: A depression between protegulum and tegulum is unique for this species. Further distinguished from most Mitrager species by a prosoma with a hump comprising the PME, and an ocular region bearing dense setae. Distinguished from M. falcifer, M. falciferoides and ‘ Oe. ’ meghalaya incertae sedis by the smaller hump elevation; from M. malearmata by the longer spike prolateral to the palpal tibia prolateral apophysis; and from M. modesta, M. lopchu and M. rustica by the smaller body size.
Description:
Male (holotype): Total length: 2.40. Prosoma: 1.01 long, 0.77 wide, PME- and postocular region slightly elevated, with one strong seta at peak of elevation pointing forwards, interocular region with strong setae pointing upwards (Figs 38R, 43B). Eyes: AME- AME: 0.04, AME width: 0.04, AME-ALE: 0.03, ALE width: 0.08, ALE-PLE: 0, PLE width: 0.07, PLE-PME: 0.07, PME width: 0.07, PME-PME: 0.11. Clypeus: not hirsute. Sternum: 0.59 long, 0.57 wide. Chelicerae: stridulatory striae imbricated, rows widely and evenly spaced (Fig. 39R). Legs: Tm I: 0.56. Pedipalp: patella prolateral proximal vertical macrosetae present; tibia with one prolateral, two retrolateral trichobothria; TPS scaly, retrolaterally pointed; TPA absent; TRA bent retrolaterally; PC short, base not visible from dorsal view, distal setae close to distal clasp, distal clasp without striae, directed retrolaterally (Fig. 42A); T without papillae; PT with long papillae, a depression between T and PT creates a discontinuous appearance from lateral view (Fig. 42D); MSA present (Fig. 42D); DSA not pointed, not retrolaterally curved (Fig. 42A); EM flat, anterior margin without obvious papillae, exceeds ARP (Fig. 42D); ARP pointed, angled at tip; LER with striae on distal margin, extended dorsal to E; VRP absent; TP round at tip, ventro-posterior area with round extension (Fig. 42B); E retrolaterally spiral, anterior margin at base slightly wavy (Fig. 42B). Opisthosoma: dorsal pattern see Fig. 40S; PMS with mAP, AC absent; PLS with triad, one AC (Fig. 42E).
Male (paratype): Total length: 2.39. Prosoma: 1.05 long, 0.86 wide. Legs: Tm I: 0.59.
