Pseudomicrocentria Miller, 1970

Type species. Pseudomicrocentria minutissima Miller, 1970 .

Revised diagnosis. The discovery of P. uncata , new species, warrants the diagnosis of the genus as given by Locket (1982) to be refined. Species of this genus are small-sized (total length 1.10–1.40) with an unmodified carapace. The formula of leg chaetotaxy is 2.2.2.1, metatarsi I–III each with a trichobothrium. The male palp is characterised by a very simple structure of the embolic division, the radix being continuous with the embolus. The palpal structure is very similar to that many erigonine genera, particularly Tapinocyba Simon, 1884 . The genus Pseudomicrocentria is easily distinguished from Tapinocyba by the absence of sulci on the male carapace, as well as by the formula of leg chaetotaxy 2.2.2.1 vs. 1.1.1.1.

Speciesincludedandtheirdistributions. Pseudomicrocentria minutissima has been recorded from the Democratic Republic of the Congo ( Miller, 1970), Nigeria (Locket & Russel-Smith, 1980), and the Republic of South Africa ( Jocqué, 1984). Pseudomicrocentria simplex Locket, 1982 , is known only from Singapore ( Locket, 1982). A third species of the genus, P. uncata , new species has been collected on Borneo, East Malaysia and is described below.
