description: Agnotecous humboldti Robillard n. sp.
(Figs 1 A, C–E)
Type material. Holotype male: New Caledonia. Grande Terre, upper Ngoe riv. [Ngoye river] nr [near] Mts Nikando [Nekando] & Humboldt, 21–29.V.1914, P.D. Montague (BMNH-BM-1946-210).
Type locality. New Caledonia, Grande Terre, upper Ngoe river.
Etymology. Named after the type locality.
Distribution. New Caledonia, Grande Terre, Province Sud, rivière Ngoye.
Diagnosis. Species small, close to A. nekando n. sp. and A. chopardi Desutter-Grandcolas, 2006 from which it differs by the shape of the pseudepiphallus in male genitalia.
Description. Size small for the genus, slender in shape. Colouration little contrasted, mostly dark brown. Head dorsum with 6 dark brown longitudinal bands separated by yellow lines. Fastigium brown. Scapes light brown with dark brown patterns anteriorly. Cheeks black, with 2 yellow spots ventrally. Face brown, with 4 yellowish spots and a median yellow stripe on front head. Mouthparts: mandibles black basally, then whitish; labrum whitish mottled with brown; palpi light brown with yellowish rings. Pronotum: Dorsal disk almost homogeneously dark brown. Lateral lobes black. Legs: FI, FII yellow brown with dark brown spots; TII brown with a yellow ring; tarsomeres brown. Legs III almost homogeneously yellow brown. TIII serrulation: 6 inner and 10 outer spines above spurs; 5 inner and 7 outer spines between spurs. Tarsomeres III-1: 1 spine on dorsal inner edges; 3 spines on dorsal outer edges; 1 outer lateral spine at one fourth of tarsomere length. Abdomen and cerci almost homogeneously brown.
Male: FW not reaching abdomen mid length. Dorsal field clearly shorter than lateral field. FW colouration homogeneously brown. FW venation (Fig. 1 A): CuP absent; diagonal faint, barely visible anteriorly; harp triangular, raised posteriorly, with one complete transverse vein; c1 cell wide, crossed by a transverse vein; D alignment little differentiated, limited to mirror (d1) and d2. Apical field restricted to one cell in E alignment (e1). Lateral field: Latero-dorsal angle made by MP; distal part of MP weak, fusion with MA not visible; R bifurcated once before mid length; ventral part of lateral field with 5 longitudinal veins.
Male genitalia (Figs 1 C–E): Very similar to that of A. chopardi and A. nekando n. sp. Dorsal face of pseudepiphallic sclerite with lateral crests more separated than in A. nekando n. sp.; median process shorter than in A. nekando n. sp., with unclear apical teeth, maybe broken in the holotype. Pseudepiphallic apex with ventral crest oriented posteriorly and conspicuous on dorsal view.
Female: unkwown.
Juvenile: unkwown.
