Borneomyia acanthophora Brake , n. sp.

( Fig. 5 )

Genus nov 1, sp. 2, in Brake 2000.

This species differs from Borneomyia tigra n. sp. in the following characters: Pedicel with 3 strong setae that are longer than the basoflagellomere. Basal scutellar seta 1.1–1.2x as long as apical seta. Male epandrium with a few more setae and setulae; posterior lobe of surstylus with an additional setula on lateral aspect. Female ovipositor: Sternite 8 bent on medial line, covered with short spine­like setulae on ventral half (fig. 5); cercus with a long spine­like seta at tip.

Type material. Holotype female: INDONESIA. North Sulawesi: Dumoga­Bone N.P., 0.34' N, 123.54' E, 232 m, malaise trap sample forest 'Rintice 3', 3.–16.ix.1985, A.H. Kirk­ Spriggs, NMW Indonesia Expedition 1985 (Project Wallace) NMW.Z 1985.078. The holotype is mounted on a cardboard triangle, is in good condition, and is deposited in the National Museum and Galleries of Wales, Cardiff (NMWC). Paratypes: 1 Ψ, same collection data as holotype (BMNH). MALAYSIA. Sabah: mainline West, 56 km West of Silam, 1200 m, seven year old selectively logged forest, malaise trap sample No. 12, 7.– 25.ix.1987, A.H. Kirk­Spriggs. NMW Sabah (Borneo) Expedition NMW.Z. 1987.094 (1 Ψ, USNM). PAPUA NEW GUINEA. Popondetta, 25 m, light trap, vi.1966, Shanahan­Lippert (1 ɗ, 1 Ψ, BPBM).

Etymology: The species name is derived from the Greek acantha = spine and phoreo = carry, denoting the conspicuous seta on the cerci. The epithet is to be treated as an adjective.

Comments: The male paratype from Papua New Guinea is in bad condition (head missing), and the species identity could only be ascertained by the length of the scutellar setae.
