Gondwanoscurus malaysiensis Jezek, 2001: 10 (original description).

Diagnosis. Larva: Unknown. Pupa: Unknown. Adult: Male antennae: flagellomeres with nodes exserted laterally; ascoids with three branches. Male head: eye bridge contiguous over three facet diameters. Male terminalia: gonostyli simple, with apical 1/3 constricted, digitiform, sinuous; distiphallus comprised of paired, acuminate sclerites; cercopodia elongate, about 9 times longer than wide, bearing 13 retinacula dorsoapically; retinacula with apices simple. Female unknown.

Description. Adult Male See Jezek (2001).

Adult Female Unknown.

Type material. Holotype [adult male]: MALAYSIA [ FEDERATION OF MALAYA]. Perak: Hulu, Belum Expedition, Belum Camp, 5°30’N 101°26’E, iv–vi.1994, coll. light trap; deposited in Slovene Natural History Museum, Ljubljana. Specimen dissected, mounted on micro-slide. Paratypes: same data as holotype, light trap [2 adult male (slides)], deposited in Ljubljana and in the Department of Entomology of the National Museum (Museum of Natural History), Prague [Cat. No. 33859].

Other records. THAILAND. Sakon Nakhon Province: Phu Phan National Park, behind forest protection unit at Huay Wien Prai, 17°06.863’N 10400.327’E, 10–17.ii.2007 Malaise trap [1 adult male (slide)], coll. W. Kongnara, [T-1689]; Phu Phan National Park, north of well, 17°03.543’N 103°58.452’E, 20–30.i.2007, Malaise trap [1 adult male (slide), 1 adult male (EtOH)], coll. S. Tongboonchai, [T-1525].

Distribution. Known from the type locality in Malaysia and two localities in Thailand.

Remarks. Adults of G. malaysiensis are similar in appearance to G. cruciferus . A suite of characters including the antennal flagellomeres with laterally exserted nodes and three-branched ascoids, eye bridge contiguous over three facet diameters, and retinacula with simple apices in the male will reliably separate G. malaysiensis from other known species in this group. The shape of the head (particularly the width of the vertex) in G. malaysiensis also appears to differ from that in G. cruciferus . The holotype of G. malaysiensis was not examined, but several Thai specimens examined matched Jezek’s original description.
