MITRAGER TRICEPS (TANASEVITCH, 2020) COMB. NOV.

Oedothorax Triceps Tanasevitch, 2020a: 288 ( Figs 8–11 , 28–30 ) (Dm).

Type material: Holotype: Nepal: Bagmati Province, Dobate Ridge northeast of Barahbise , 2800 m a.s.l., sifting rotten wood, dead leaves and moss in oak grove with Rhododendron , 2.v.1981, leg. I. Löbl & A. Smetana ( MNHG, not examined).

Diagnosis:

Males: This species is characterized by the prominent trilobate post-ocular groove and hump, as well as the short palpal prolateral apophysis, the distally oriented palpal prolateral spike, the protegulum palpillae and the embolic division [see description in Tanasevitch (2020b)]. These features, shared with M. tholusa , suggest a close relationship between them, but they can be distinguished by the position of the palpal tibia prolateral apophysis, which is more distally situated in M. tholusa than in this species.
