Negritothripa confluens Mell stat. & comb.
Lamprothripa orbifera confluens Mell, 194, Zool. Jb. Syst., 76: 200.
Diagnosis and taxonomic note. The forewing facies is similar to that of
orbifera but a more uniform violet-grey, lacking distinctly paler elongate
patches on the dorsum; these patches are a slightly greener or browner colour
basally and centrally. The reniform and transverse fasciae are distinct, fine,
darker, and the general colour of the wing is a darker grey distal to the
postmedial and, in the holotype, paler and greenish basal to it in the medial
area around the reniform. In the darker distal area there is a diagnostic paler
ring at the tornus. In Javan material the basal zone of the wing is not so
distinctly paler than the distal one. The male genitalia are distinguished from
orbifera and hampsoni by the broadened, rather bifid apex to the
dorsal arm of the valve and the more distinctly paddle-like shape of the ventral
arm (broader distally).
Geographical range. Borneo, Java.
Habitat preference. Two specimens collected during the Mulu survey are from
lower montane forest at 900m on G. Api and 1000m on G. Mulu. The holotype female
was taken on G. Kinabalu by Waterstradt, but no altitude was recorded. The Javan
series in BMNH (slides 16983, 16987) is from a similar altitude or higher.
