Lamellisphecia champaensis Kallies & Arita, 2004

Figs 3, 4, 10

Material examined. Holotype: ♂, Vietnam, Lam Dong Prov., Bao Loc, Dambri , ca. 850 m, 7.viii.2001, Y. Arita leg. ( Fig. 3, NSMT) . Additional material: 2♂, same locality, 3.v.2003, Y. Arita leg. ( Fig. 4, NSMT) ; 2 ♂, Laos, Houapan Prov. , Xamneua Distr., Ban Saleui, 1350 m, 24.vi.2003, S. Nagai leg. ( NSMT) ( 1 ♂, genitalia examined, prep. AK871, Fig. 10) .

This species was known only from the holotype ( Fig. 3). We can now report two additional specimens from Vietnam, collected at the type locality, and two specimens from Laos. The two additional specimen from Vietnam differ from the holotype by the more extensive yellow-orange marking of the abdomen, with tergite 3 being reddish orange and tergite 4 yellow-orange. The two specimens from Laos differ from the ones from Vietnam by having tergite 5 completely yellow-orange in addition to tergites 3 and 4 ( Fig. 4). Although this gives them a quite different appearance, they do not show additional distinctive features. We therefore believe that these specimens belong to L. champaensis as and suggest that the extent of yellow-orange markings on the abdomen alone is not suitable to separate different species.
