Figs 1–2 View Fig View Fig , 3B View Fig

Diagnosis

Male 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 View Fig ). Female abdominal tergites lighter than male’s or concolorously light.

Remarks

This 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.
