‘ OEDOTHORAX’ SOHRA TANASEVITCH, 2020 INCERTAE SEDIS

Oedothorax sohra Tanasevitch, 2020b: 129 , figs 4–6, 13–18 (Dm).

Type material: Holotype: India: Meghalaya, Sohra , plateau, 1320 m a.s.l., 14–26.xii.2013, leg. K. P. Tomkovich ( ZMMU).

Diagnosis:

Males: The palpal morphology of this species is similar to many ‘ Oedothorax ’ incertae sedis species from the Oriental Region, including ‘ Oe. ’ kodaikanal , ‘ Oe. ’ meghalaya , ‘ Oe.’ uncus , ‘ Oe. ’ cunur , ‘ Oe. ’ stylus , ‘ Oe. ’ myanmar , ‘ Oe. ’ khasi , ‘ Oe. ’ bifoveatus and ‘ Oe.’ unciger . It can be distinguished from ‘ Oe.’ cunur and ‘ Oe.’ stylus by the much longer, dorsally directed palpal tibial prolateral apophysis with distal dentation; from ‘ Oe.’ kodaikanal , ‘ Oe.’ meghalaya , ‘ Oe.’ unciger , ‘ Oe. ’ khasi , ‘ Oe. ’ bifoveatus and ‘ Oe.’ myanmar by the much longer and distally curved ventral radical apophysis; from ‘ Oe.’ uncus by the shorter and less curved ventral radical apophysis.

Females: Unknown.

Distribution: Only known from the type locality in India.

Remarks: From the original species description and figures ( Tanasevitch 2020b: 130, figs 13–18) this species is overall most similar to ‘ Oe.’ uncus , both in the lack of prosomal modification and the male palpal morphology, including the extensive papillae distribution on the protegulum, the long and curved ventral radical apophysis and the long, vertically pointed palpal tibial prolateral apophysis with distal dentation, etc. Therefore, this species is probably most closely related to ‘ Oe.’ uncus instead of Oedothorax s.s..
