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

Colour as in H. borneoensis .

Male genitalia with subgenital plate strongly constricted sub-basally with long digitate apex; with short fine dorsolateral setae. Connective with arms long, appressed; stem shorter than arms, broad in lateral view, produced distally into a long caudal process, curved dorsally, bifurcate apically. Aedeagus with basal area broad in lateral and dorsal view, shaft with two pairs of elongate dorsally directed processes the more apical pair bifurcate apically, gonopore arising near apex on ventral surface.

Material examined. Holotype: ♂, Malaysia, Sarawak, Gunung Mulu National Park , P.M. Hammond & J.E. Marshall, v-viii.1978, NHMUK 010591759 ( BMNH).

Etymology. This species is named for the four apical processes on the aedeagus.

Remarks. This species can be distinguished from all other Hecaloidella species by the shape of the connective in lateral view and aedeagus (see description).
