Oedothorax paracymbialis Tanasevitch, 2015: 389 View in CoL , figs 70–74 (Dm).

Type material: Holotype: India: Madras , Nilgiri , Hulical near Coonoor, right bank of Coonoor River, 1600 m, forest in ravin, sifting, ♂ 22.xi.1972, leg. C. Besuchet & I. Löbl ( MHNG, examined) .

Diagnosis:

Males: This species can be diagnosed by the slightly elevated postocular region, the prominent TPS and the large distal part of paracymbium.

Description:

Male (holotype): Total length: 1.77. Prosoma: 0.77 long, 0.63 wide, postocular region slightly elevated, with curved seta directed anteriorly ( Fig. 7C View Figure 7 ). Eyes: AME-AME: 0.031, AME width: 0.04, AME-ALE: 0.03, ALE width: 0.08, ALE-PLE: 0.01, PLE width: 0.08, PLE-PME: 0.03, PME width: 0.07, PME-PME: 0.06. Clypeus: not hirsute. Sternum: 0.48 long, 0.49 wide. Chelicerae: mastidia absent; stridulatory striae rows widely and evenly spaced ( Fig. 67D View Figure 67 ). Legs: Tm I: 0.62. All metatarsi with trichobothrium. Pedipalp: patella prolateral proximal vertical macrosetae absent; tibia with one prolateral, two retrolateral trichobothria; TPS striped, straight, apical-retrolaterally pointed, wide at base; TPA slightly elevated; TRA absent ( Fig. 79C View Figure 79 ); PC large, base not visible from dorsal view, distal setae close to distal clasp, setae-bearing region greatly enlarged, distal clasp without striae, clasp directed slightly apically ( Fig. 79A View Figure 79 ); T without papillae; PT short, without papillae, distal rim thin and smooth at margin; TS absent ( Fig. 79D View Figure 79 ); MSA present; DSA straight, tip round; EM absent; ARP horizontally flat, highly sclerotized; LER small, without striae, not extended dorsal to E; VRP absent; TP slender; E retrolaterally spiral, middle part wide and striped ( Fig. 79E View Figure 79 ). Opisthosoma: dorsal pattern see Fig. 68D View Figure 68 ; PMS with mAP, two AC; PLS with triad, three AC ( Fig. 79F View Figure 79 ).

Female: Unknown.

Distribution: Only known from the type locality.

Habitat: Forest litter.

Remarks: According to the results of our phylogenetic analysis, and the lack of the distinctive characteristics of Oedothorax s.s., this species is more closely related to species in Clade 16 that, as this species, are distributed in the Oriental realm. We provisionally leave the taxonomic status of this species unchanged until further data become available.
