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.
