Type material.

Holotype, male (EMEC80961), "NEW CALEDONIA, Pic Ningua summit, 1350m, 21°47.8'S, 166°8.3'E 21°47.8'S 166°8.3'E, collected by pitfall trap, in primary montane rainforest, site L, 19 February 1995, G.Hunt collector" deposited MNHN. Paratypes, same data as holotype except dates, as follows: 9 January 1993- 2 males (EMEC80959, EMEC80960); 24 January 1994-1 male (EMEC80958) and 1 female (EMEC80957) [CAS].


Size. Overall length (sbl) 7.5-8.8mm, greatest width over elytra 2.8-3.5mm. Color. Dorsal and ventral surfaces black some individuals with a slight bronze reflex from elytra. Legs, mouthparts, and antennae slightly or noticeably paler than ventral surface of body, piceous to rufopiceous or concolorous with ventral surface and then nearly black. Luster. Dorsally and ventrally moderately shiny to slightly dull, elytra usually slightly duller. Iridescence. Elytra and ventral surface of body with no or only a very slight spectral iridescence, otherwise lacking. Head. Dorsal microsculpture with microlines well impressed, readily visible at 30x magnification, sculpticells isodiametric or slightly irregular, forming mesh, clypeal-ocular sulci deeply impressed, linear, divergent, ended short of anterior supraorbital seta, ocular ratio 1.38-1.45, eyes average size, rounded prominent. Labrum flat. Antennae: Overall length moderately long, reaching base of pronotum, antennomeres 5-11 elongate. Thorax. Pronotum nearly quadrate, sides evenly rounded from apex to near base, marginal bead continuous from apex to base, not extended along basal margin, ended at hind angle which forms a distinct angular jag, anterior margin slightly emarginate with anterior angles moderately produced, inner basal impression linear and well impressed, outer impression shallowly or deeply impressed, area laterad of hind outer impression convex, hind margin between basal impressions with more or less distinctly impressed border, seta at hind angle not more than one pore width forward of basal margin in contact with lateral channel. Dorsal surface moderately shiny, microsculpture readily visible as irregular mesh of microlines at 20x magnification. Elytral striae complete, well impressed and impunctate. Parascutellar stria and angular base of stria 1 present. Elytra moderately shiny, microsculpture readily visible at 20x as mesh of microlines. Metacoxal sulcus straight or slightly arcuate and ended well before lateral end of coxa. Abdomen. Last abdominal ventrite with narrow, light apical bead. Male aedeagus (fig. 13G-H) in dorsal view nearly straight to distal edge of ostium and then curved right, tip rounded.


Latin fortis, treated as an adjective, alludes to the well impressed basal impressions of the pronotum.
