Roepkiella javanus Roepke

Cossus javanus Roepke, 1957: 9.

Cossus chloratus sensu Roepke, 1957: 7.

Diagnosis

See Cossus chloratus Swinhoe. The uniserrate/pectinate antennae of the male have the pectinations tapering away over the apical quarter only rather than over the whole length.

Geographical Range

Java; Peninsular Malaysia, Sumatra, Borneo.

Habitat Preference

The species is found in lowland rainforest.

Taxonomic Notes

The male genitalia of typical Javan material have the valves somewhat narrower and more subapically constricted than elsewhere in the geographical range. The forewing pattern appears to be similar, however.

Yakovlev (2004b: 374) described a new Bornean species, Paracossus microgenitalis Yakovlev (Plate 6, Fig 87). The holotype was from 1450m at Apin Apin on G. Trus Madi in Sabah. Two further specimens from Sabah have been seen, both males: 620m in undisturbed Agathis hill forest at Ginseng Camp, Maliau Basin (in FRC, Sepilok); 900m in stunted hill forest on Bukit Monkobo (in BMNH). The forewings are a satiny white, striated and shaded with dark greyish brown as illustrated. This shading is strongest on the dorsum with a strong extension into the medial zone that then extends more weakly and obliquely to the apex.
