Comparative diagnosis
This new subspecies is very similar to the trans-tropical Hemidoryctes carbonarius carbonarius (Ashmead, 1894), but differs from it by the distinctly postfurcal position of the fore wing recurrent vein
(m-cu) (always antefurcal in H. c. carbonarius) and recorded only in Yemen (with wide pantropical distribution for H. c. carbonarius).
Etymology
Named after the postfurcal position of the recurrent vein (m-cu) in the fore wing.

Nervulus (cu-a) strongly postfurcal, distance from nervulus (cu-a) to basal vein (1-M) 1.6–2.0 times nervulus (cu-a) length. Brachial (subdiscal) cell open apically, but present short brachial vein (CU1b). Parallel vein (CU1a) weakly curved basally. Hind wing 5.0–5.2 times longer than wide. First abscissa of costal vein (C+SC+R)about as long as second abscissa. Medial (basal) cell rather narrow, weakly widened posteriorly, 11.0–13.0 times longer than wide, 0.4 times as long as hind wing.
