Tribe Rhinotini Hoffman, 1977

Diagnostic remarks. The newly described genus and the three species can be placed in the tribe Rhinotini based on the following characters shared with the genera Rhinotus Cook, 1896, Siphonoconus Attems, 1931, and Eumillipes Marek, 2021: Anterior gonopod with two podomeres on large sternite; posterior gonopod with three or more podomeres, the podomere IV being thin and elongated (compare Hoffman 1977, 1980). Also, the presence of feathery serrated setae on the sternite of the gonopods (Fig. 6H), as found in several species of the genera Rhinotus (see Carl 1926; Golovatch & Korsos 1992; Wesener 2014) and Siphonoconus (see Attems 1931) places Theratta n. gen. in the tribe Rhinotini .
