Chinese name

Diagnosis

Prescutum almost dark brown, reddish brown laterally, with four slightly brown, vague stripes; tergite 9 with two pairs of horn-like protrusions, middle pair directed outward and side pair directed inward.

Etymology

This species is named after the shape of the outer and inner gonostyli, similar to the crane courtship call pose, the word ‘ heming ’ being from the Chinese ‘ḃñ’ in the ancient Chinese poetry collection ‘Book of Songs (Xiaoya, Heming),’ literally meaning the crane is chirping.

OutwaRd part of outer gonostylus nearly square, anterior margin with a small triangular protrusion; inward part slendeR, like a cRane head ( Fig. 41 ).

Unknown.

Distribution

China (Xizang).

Remarks

The new species is similar to T. (S.) krishna Alexander, 1962 and T. (S.) drolma sp. nov., but in T. (S.) krishna the tergite 9 only has a pair of protrusions, and the gonostyli are simple. In T. (S.) drolma sp. nov. the protrusions of tergite 9 are longer than in T. (S.) heminga sp. nov., the protrusion of sternite 9 has no small protrusion, and the adminiculum has a pair of slender protrusions at the middle.
