Elaphropeza E59

Material examined

SINGAPORE: 1 ♀, Pulau Ubin (PU02), 12 May 2009, mangrove, Mal. (reg. 29059, leg. P.G.).

Remarks

This female specimen resembles E. luteoides in having entirely yellow occiput, eyes deeply concave on posterior margin, entirely yellow antennae with very short postpedicel and very long stylus, subequally long anterior and posterior ocellar bristles, hind tibia with 1 anterodorsal bristle, and undifferentiated acrostichal and dorsocentral bristles. However, we would hesitate to associate it with this species. It should be noted that in E. luteoides the abdominal tergite 4 is broadest, undivided, dark brown, with squamiform setae and tergite 5 is very narrow, dark brown, with squamiform setae. In Elaphropeza E59 all abdominal tergites are brownish yellow, tergites 2-6 are divided along the midline, tergite 4 bears a few slightly flattened setae and only tergite 5 bears scattered squamiform setae. We realise that these differences may be a result of sexual dimorphism but the female is unknown for E. luteoides .
