H. brevipenis Zhang & Webb sp. nov.

Figs. 1I , 6C–D

Description. Body length (including tegmina), male: 6.0– 6.3mm.

Colour as in H. borneoensis but head marking sometimes indistinct.

Male genitalia similar to H. borneoensis but shaft shorter and more evenly curved dorsally to apex and preatrium slightly longer.

Material examined. Holotype: ♂, Malaysia, Sarawak, Foot of Mt Dulit , junction of rivers Tinjar and Lejok, at light, 29.viii.1932, B.M. Hobby & A.W. Moore, Oxford University Expedition, NHMUK 010591766 ( BMNH) . Paratypes: 2♂, same data as holotype ; 1♂, same data as holotype except 3.ix.1932 ; 2♂, same data as holotype ex- cept 1.ix.1932 and 2.ix.1932 (without old secondary forest label) ( BMNH) .

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

Remarks. This species is similar to H. longipenis and from the same locality. It can be distinguished from this and other similar species by its relatively short aedeagal shaft. A series of females with the same data (various dates) similar to this and H. longipenis have been seen (BMNH), which could be either species; all have the pregenital sternite triangularly produced medially.
