Pseudoscaeva Vockeroth 1969
Description
Genus Pseudoscaeva Vockeroth, 1969 stat. rev.
Fig. 46.
Pseudoscaeva Vockeroth, 1969: 123, as a genus. Type species: Syrphus diversifasciatus Knab, 1914 (original designation). Ocyptamus (Pseudoscaeva). Mengual et al. (2012).
Ocyptamus diversifasciatus species group. Miranda et al. (2016).
Diagnosis. Dorsal occiput with 2–3 rows of pile. Mostly bare wings. Abdominal terga with pale fasciate maculae over black dull fasciae.
Comments. As the name suggests, this genus is superficially similar to Scaeva, having distinct bare areas on the wings (nowhere else among the groups studied here does the wing have such extensive bare areas). They have wide faces and frons, and the female ocellar triangle is distinctly distanced from the eye margin, and overall appearance reminds one of Orphnabaccha. A close phylogenetic relationship between Orphnabaccha and Pseudoscaeva based on morphological characters was already pointed out by Vockeroth (1969), although the metasternum is bare in Pseudoscaeva.
Species list (4): P. diversifasciata (Knab, 1914), P. meridionalis (Fluke, 1950b), P. schoenemanni (Enderlein, 1938), P. sericea (Walker, 1836).
