Sphecodopsis obscura sp. nov. urn:lsid:zoobank.org:act: 645C6F27-EA0A-4806- BEC 3-4C92C530806E Figs 25–28 Diagnosis The female of S. obscura sp. nov. can be separated from that of all other species of the genus by the combination of the following characters: S6 bifid posteriorly, apical notch three times as long as its apical width (Fig. 26C); metasoma completely black (Fig. 25B); T6 covered with long black hair (Fig. 26B). The male can be separated from that of all other species by the combination of the following characters: metasoma completely black (Fig. 25B); head and mesosoma with black hair (Fig. 27C–D). Etymology The name refers to the dominantly dark coloration of the species that is unusual in this species group.

T6 covered with long, black hair, narrow and almost straight apically (Fig. 26B). Shape of S6 (Fig. 26C) as illustrated. Male BODY LENGTH. 4.4–5.0 mm. HEAD. Head wider than long. Vertex slightly rounded, ocelli highest point. Integument black, except part of mandibles red or reddish-brown. Face covered with long, black hair mixed with short, white hair.

TERMINALIA. Genitalia (Fig. 28C), S7 (Fig. 28A) and terminal plate of S8 (Fig. 28B) as illustrated. Distribution Only known from the type locality south of Nieuwoudtville. Host bees Likely hosts are equally small species of euryglossiform Scrapter (Kuhlmann 2014; Kuhlmann & Friehs 2020) that were found in association with this cuckoo bee. Seasonal activity August.
