Bradysia centidens sp. n.

Figs 2 A–D

Material studied. Holotype male. NEW CALEDONIA, Pindaï, sclerophyllous forest, fogging, 30.vi.1992, Bonnet de Larbogne, Chazeau & Guilbert (in MNHN). Paratype. 1 male, same data as holotype (in MNHN).

Description. Male. Head. Brown, antenna unicolorous brown, apical edge of flagellomeral necks slightly darker than rest, maxillary palpus very pale brown. Eye bridge 3 facets wide. Face with 8 scattered longer and shorter setae. Clypeus non-setose or with 1 seta. Maxillary palpus with 3 palpomeres; palpomere 3 longer than palpomere 1, palpomere 2 shortest; palpomere 1 with 2 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres rough, body of flagellomere 4 ( Fig. 2 A) 2.2x as long as wide, the neck shorter than broad, the longest setae shorter than the width of flagellomere. Thorax. Brown, setae dark. Anterior pronotum with 2–3 setae. Episternum 1 with 6 setae. Scutum with long dorsocentrals, with some longer and shorter laterals, scutellum with 4 longer and some short setae. Wing. Hyalinous. Length 1.4 mm. Width/length 0.40. Veins distinct. R1/R 0.40. c/ w 0.85. r-m and than bM subequal in length. M, CuA, r-m and bM non-setose. Legs. Yellow. Coxal setae dark. Apical part of front tibia ( Fig. 2 B): tibial organ with pale vestiture forming a short row. Front tibial spur slightly longer than the tibial width. Claws without teeth. Abdomen. Setae dark. Hypopygium, Figs (2 C, D). Brown, concolorous with abdomen. Gonocoxa narrow, longer than gonostylus, mesial margin with sparse setosity. Gonostylus rather straight, broadest at middle, without an apical tooth, with a group of 5 apical megasetae and 2 more lateral megasetae, megasetae strong and slightly curved. Tegmen broader than long, weakly sclerotized, with area of numerous small aedeagal teeth.

Discussion. Bradysia centidens can be placed in the Bradysia hilaris group in the sense of Menzel and Mohrig (2000). For further discussion, see under Bradysia seticornis .

Etymology. The name is derived from the Latin words centum, hundred, and dens, tooth, referring to the very high number of aedeagal teeth.
