Taenogera Kröber

Taenogera Kröber, 1912b: 150. Type species: Taenogera longa Kröber, 1912b: 151 [=Anabarhynchus nitidus Macquart, 1850].

Could be confused with: Anabarhynchus, Ectinorhynchus, Eupsilocephala, Johnmannia.

Systematic grouping: Taenogera genus-group.

Diagnosis: Male frons width almost equal to female, fine pale setae present dorsally; multiple rows of postocular setae in male and female, occiput with silver or gold velutum; cell m3 open; hind femur with anteroventral apical seta; velutum patches absent on fore and hind femora and gonocoxites; abdomen with triangular patches of silver velutum laterally on tergites 2-4; distiphallus broad, parallel sided, parameral sheath not fused along ventral surface of distiphallus; three spermathecae.

Distribution: South-eastern Queensland and New South Wales.

Comments: Closely related to Ectinorhynchus, species of Taenogera are easily separated by their short antennae, elongate body and large body size, multiple rows of postocular setae in the male and differences in the male genitalia. Spot characters to look for when identifying this genus include velutum patches on the fore and hind femora absent, wing cell m3 open, multiple rows of postocular setae in both sexes, large, elongate body size and metallic velutum patches on a glossy, black body.
