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.
