Material studied. Holotype male. NEW CALEDONIA, Rivière Bleue N.P., (parc 7), rainforest, 21.vii.1992, Bonnet de Larbogne, Chazeau & Guilbert (in MNHN).

Description. Male. Head. Brown, antenna unicolorous, slightly paler brown, maxillary palpus very pale brown. Eye bridge 3 facets wide. Face with about 15 scattered longer and shorter setae. Clypeus with 1 seta. Maxillary palpus with 3 palpomeres; palpomere 1 longer than palpomere 3, palpomere 2 shortest; palpomere 1 with 1–2 setae, with a dorsal patch of sensilla in a depression; surface of antennal flagellomeres smooth, body of flagellomere 4 ( Fig. 3 A) 1.7x as long as wide, the neck shorter than broad, the longest setae longer than the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 2 setae. Episternum 1 with 7 setae. Scutum with long dorsocentrals, with some longer and shorter laterals. Wing. Hyalinous. Length 1.3 mm. Width/length 0.45. Veins distinct. R1/R 0.50. c/ w 0.55. r-m/bM 0.60. M, CuA, bM and r-m non-setose. Legs. Yellow. Coxal setae pale. Apical part of front tibia, Fig. 3 B: tibial organ with pale vestiture forming an indistinct row. Front tibial spur slightly longer than the tibial width. Middle and hind tibiae with a normal and a shortened spur. Claws without teeth. Abdomen. Setae dark. Hypopygium, Figs 3 C, D. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, with sparse setosity. Gonostylus narrow, slightly curved, narrowed towards apex, with the mesial side distinctly impressed; with sparse apical vestiture, with a strong apical tooth, with one subapical and one mesial megaseta, the latter with a distinct basal body. Tegmen subquadrangular, weakly sclerotized, with a small area of aedeagal teeth, aedeagal apodeme long.

Discussion. See under Scatopsciara spiculata .

Etymology. The name is derived from the Latin word tenuistylata , thin, referring to the narrow gonostylus of the species.
