The poorly known Central Asian trap-door spider Ummidia gandjinoi was de­scribed by Andreeva (1968) from a single male as a representative of Pachy­lo­merus Ausserer, 1871 (preoccupied in Coleoptera). Brignoli (1983) transferred this species to Ummidia Thorell, 1875, and Zonstein (2008) described the conspe­cific females. Although the male holotype had been described fairly adequately to dis­tinguish U. gandjinoi from its closest congeners, its depository for a long time was considered unknown, and the specimen was assumed to be lost. However, the holotype has been quite unexpectedly detected by Dr W. Wawer, the cu­ra­tor of the spider collection deposited at the Museum and Institute of Zoo­lo­gy, War­saw, Poland (MIZW), who sorted and prepared the loan requested for a re­vi­sion of the cyrtaucheniid Anemesia Pocock, 1895. It was found among the vials with the paratypes of Brachythele karatauvi Andreeva, 1968, and with some other re­presentatives of Anemesia. The redescription of the borrowed and exa­mined ho­lotype of U. gandjinoi is provided below.
