Two new goblin spiders: Promolotra shankhaung and Promolotra hponkanrazi

Promolotra shankhaung

The spider family Oonopidae, commonly known as goblin spiders, consists of over 1,800 described species. Most of them are tiny, measuring only about 1 to 3 millimeters. As a result they are seldom seen by people as they are too small to be noticed. They are generally found in leaf litter and under rocks, but they also make up a significant component of the spider fauna living in the canopy of tropical rainforests.

Both spiders were found in the area of the Putao township in Kachin State, Myanmar. They were names after the respective discovery sites.   

For the experts: A new genus, Promolotra gen. nov., including two new species, P. hponkanrazi sp. nov. (♂♀) and P. shankhaung sp. nov. (♂), is described from Myanmar. The new genus is similar to Molotra Ubick & Griswold, 2011 but can be distinguished by the completely fused bulb and cymbium, the presence of a receptacle, the absence of grooves connecting either the anterior or posterior pairs of spiracles, and the incised labium of both sexes.
