NOV. ( FIGS 19G , 22G , 23 , 24G ) Oedothorax convector Tanasevitch, 2014a: 408 , figs 64–71 (Dm). Type material: Holotype : Thailand : Chiang Mai Province , Chomthong District, Doi Inthanon, 1780 m , ♂ 3.iii.1987 , leg. P. Schwendinger (MHNG, examined). Diagnosis: Males: This species can re recognized by the shape of prosomal modification with the inter-AME-PME groove and PME lobe; it can be discriminated from Oedothorax s.s. , Mitrager and other Callitrichia species by its palpal features including the presence of tibial retrolateral apophysis with setae (no setae in Mitrager ), the absence of tibial prolateral trichobothrium, the shape of paracymbium (distal clasp particularly long and slender), and the radix without tail piece. Description: Male ( holotype , MHN): Total length: 1.68. Prosoma: 0.75 long, 0.55 wide, PME on frontal side of elevated region, short curved setae grouped at both sides of dorsal surface of prosomal elevation behind PME, inter-PME-PLE groove, three pairs of strong setae at groove lower margin, no setae inside groove ( Fig. 19G ). Eyes: AME-AME: 0.03, AME width: 0.05, AME-ALE: 0.01, ALE width: 0.05, ALE-PLE: 0.01, PLE width: 0.05, PLE-PME: 0.10, PME width: 0.05, PME-PME: 0.18. Clypeus: not hirsute, one sub-AME seta, particularly long. Chelicerae: stridulatory striae rows wide and evenly spaced ( Fig. 22G ). Sternum: 0.46 long, 0.5 wide. Legs: dorsal proximal macroseta on tibia IV 3.13 times diameter of tibia; Tm I: 0.81. Pedipalp: TPA narrow, slightly curved; TRA extended anteriorly, covering PC base from retrolateral view; PC long, distal-setae-bearing middle part enlarged, distal clasp slender and long ( Fig. 23A–C ); T without papillae; PT slender and long, with scale-like papillae; TS long, with small papillae; MSA absent; DSA short and wide ( Fig. 23H ); EM short, without papillae, not exceeding ARP ( Fig. 23E ); R without TP, scaly region distributed from ARP to VRP; LER present; E prolaterally spiral, between ARP and LER ( Fig. 23E, F, G ). Opisthosoma: dorsal pattern see Fig. 24G ; PMS with mAP, two AC; PLS with one FL, 3+ AC ( Fig. 23I–K ). Female: Unknown Distribution: Only known from the type locality in Thailand . Habitat: No data.
