Figs. 1Q , 8A–D

Description. Body length (including tegmina), male: 5.2–5.5mm; female: 5.5mm.

Colour as in H. brunnifacialis .

Male genitalia similar to H. brunnifacialis but style lateral lobe more produced ( Fig. 8C ).

Female pregenital sternite with posterior margin conically rounded ( Fig. 8D ).

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 ( BMNH) . Paratypes: 1♂, same data as holotype except 29.viii.1932 , NHMUK 010591760; 1♀, same data as holotype except old secondary forest ; 1♀, same data as holotype except 2.ix.1932 ( BMNH) .

Etymology. This species is named after the four spots on the mesonotum.

Remarks. This species is very similar to H. brunnifacialis but is considered distinct as it has a more produced style lateral lobe and the female pregenital sternite is conical rather than with the posterior margin produced medially.
