Description

Deltotus Séguy, 1935

Deltotus Séguy, 1935: 99. Type species: Deltotus facetus Séguy, 1935.

Diagnosis. Colouration dark-brown to bluish-green or purplish, legs brown to yellow; wing without maculae. Female with proclinate fronto-orbital seta; parafrons weakly setulose on upper half; interfrontal seta absent. Dorsocentrals 2+2. Presutural acrostichals developed; one postsutural pair. Postsutural intra-alars 2; intrapostalar present. Prosternum enlarged anteriorly and widely setulose. Katepisternals 1+3. Meron and katepimeron bare. Anatergite setulose. Postalar wall setulose. Anterior suprasquamal ridge setulose. Wing with R1 setulose dorsally; Rs node and R4+5 setulose dorsally and ventrally; M bent forward towards R4+5. Lower calypter glossiform. Subcostal sclerite densely setulose ventrally. Calcar strong. First abdominal sternite setulose on lateral margins.

Comments. Deltotus is one of the three genera with a setulose postalar wall. This character groups the clade (Deltotus + (Pyrellina + Polietina )) (Nihei & de Carvalho 2007a), with the former two genera Afrotropical in distribution and the latter Neotropical.

Distribution (3 species). Afrotropical (Madagascar).
