Astochia Becker, 1913

Astochia Becker, 1913: 538. Type species: Astochia metatarsata Becker, 1913 (Taf. XII fig. 9 (head)), by monotypy.

Diagnosis.

Based largely on the key characters used by Londt and Dikow (2017). Head: Antennal stylus lacking setulae. Palpus 1-segmented. Thorax: Anepisternum lacking strong macrosetae at superoposterior angle. Anatergite setose. Postmetacoxal area membranous. Wings: Alula well developed. Cells r 1 m 3 and cua closed at or before wing margin. Legs: Fore tibia without distal spine-like processes. Tarsi with well-developed pulvilli. Abdomen: Tergite 2 not more than 4 × as long as wide, sternite 1 confined beneath tergite 1. ♀ with segments 1-5 pruinose (1-6 in A. sodalis ), terminal four segments apruinose (three in A. sodalis ), forming a telescopic ovipositor.

Note.

The key to genera published by Londt and Dikow (2017) is now partly defective in as much as couplet 136 states that the scutellum has fewer than 4 apical macrosetae. The newly described A. silva possesses four or more such macrosetae.
