Figs. 1K , 6G–J

Description. Body length (including tegmina), male: 6.2–6.3mm.

Colour as in H. borneoensis .

Male genitalia similar to H. borneoensis but aedeagal shaft lacking a sinuate apex and the gonopore arising slightly basad of mid-length on ventral surface.

Material examined. Holotype: ♂, Malaysia, Sarawak, Foot of Mt Dulit , junction of rivers Tinjar and Lejok, at light, 25.ix.1932, B.M. Hobby & A.W. Moore, Oxford University Expedition, NHMUK 010591763 ( BMNH) . Paratype: 1♂, same data as holotype except River Kapah , tributary of River Tinjar ( BMNH) .

Etymology. This species is named for its relatively long aedeagal shaft.

Remarks. This species is similar to H. borneoensis and from the same locality. It can be distinguished from this and other species by its relatively long aedeagal shaft with gonopore arising at approximately mid-length of shaft on ventral surface. See also Remarks under H. borneoensis .
