Ummeliata Strand, 1942

Type species. Hummelia incisa Schenkel, 1936 .

Revised diagnosis. The discovery of U. jambi , new species, warrants the diagnosis of the genus as given by Eskov (1980, as Hummelia ) to be refined. Species of this genus are smallsized (total length about 2.0–3.0) with a modified carapace. The formula of chaetotaxy is 2.2.1.1, metatarsi I–IV each with a trichobothrium. The male palp is characterised by the presence of a large convector, a relatively long and coiled embolus, and a totally or strongly reduced radix in the embolic division. By having a large body, the chaeto- and trichobothriotaxy patterns, the modified male carapace, the long and coiled embolus, and the strongly reduced radix, Ummeliata resembles Nasoonaria Wunderlich & Song, 1995 . However, Ummeliata clearly differs from the latter by the absence of a convector in the embolic division, as well as by the poorly developed distal suprategular apophysis, which is hypertrophied in the males of Nasoonaria .

Species included and their distributions. The genus includes nine species distributed in the southeastern parts of the Palearctic ( World Spider Catalog, 2020), but one species, U. insecticeps ( Bösenberg & Strand, 1906) , has also been recorded from the Oriental Region: northern Vietnam ( Tu & Li, 2004), and is here reported from northern Laos and northern India for the first time, as shown below. The new species, described below, is the second representative of the genus to be registered in the Oriental Region.
