Drosophila tsacasi Bock & Wheeler 1972
Description
‘ D. tsacasi species complex’ new complex
Figs 1–2, 3B
DiagnosisMale abdominal tergites T2–T5 yellowish with usually distinct black stripes, T6 usually black; cercal ventral lobe (secondary clasper) fused to cerci with four or five very large curved black medial teeth arising from long dark chitinous roots on the internal margin; surstylus lobate with a lateral row of long, irregularly spaced prensisetae on the outer margin and a cluster of prensisetae on the inner margins (no medial prensisetae), the innermost one significantly long (Fig. 3B). Female abdominal tergites lighter than male’s or concolorously light.
RemarksThis complex contains two described species, D. tsacasi and D. seguyiana, and two putatively new species, D. aff. tsacasi (see above under D. curta) and D. aff. bakoue (see above under D. bakoue). The molecular, morphological and reproductive isolation between these species requires further investigation.
Taxon contentD. tsacasi Bock & Wheeler, 1972.
