Genus Orintia Gorochov, 1986
Orintia Gorochov, 1986a: 698 . — Otte et al. 1987: 412.
TYPE SPECIES. — Orintia incrustata Gorochov, 1986 by original designation.
ILLUSTRATIONS. — Habitus: Fig. 6A View FIG ; Gorochov 1986a: fig. 27. Male genitalia: Fig. 7. View FIG
EMENDED DIAGNOSIS. — Small to medium apterous nemobiines with a very wide head. Coloration pattern distinctive: body variegated orange, dark brown, black and ivory; pronotum often with a wide V-shaped ivory area covering part of DD and LL, with posterior part of LL black; head dorsum lightly coloured; antennae pubescent and annulated dark and white; last three joints of maxillary palpi white; abdomen light brown or orange brown with rows of brown dots and two squared black spots. Head and body with long and thick setae. Head distinctly large, wider than body, and much wider than high in front view ( Fig. 6 View FIG ). Eyes very wide but not protruding; distance between epistemal suture and lower margin of eye shorter than eye mid width. Joint 5 of maxillary palpi long compared to joints 3 and 4, regularly widened toward apex ( Fig. 8A View FIG ). Pronotum transverse; wider anteriorly than posteriorly, which gives the body a particular shape. TI with a small outer tympanum; no inner tympanum; two apical spurs. TII with three long apical spurs (only two in O. cornuta Desutter- Grandcolas, n. sp.). TIII short compared to FIII; with three outer and three inner apical spurs; with three pairs of relatively short and alternate inner and outer subapical spurs, getting slightly longer toward TIII apex. Basitarsomeres very long; hindbasitarsomeres longer than half TIII.
Males. Face plain or slightly concave at level of epistemal suture; with a pair of long horns in Orintia cornuta Desutter-Grandcolas , n. sp. ( Fig. 6 View FIG B-D). Metanotum and tergites without glandular structures. Subgenital plate short and low. Male genitalia ( Fig. 7 View FIG ) short and wide; margins of pseudepiphallic sclerite straight or slightly convex; main part of pseudepiphallic sclerite clearly more sclerotized, broadly squared; a pair of short apical lobes, rounded or rectangular; lateral lobes dejected laterally, distinctly separated from pseudepiphallic sclerite, about as long as median lobes, their distal margin somewhat coiled and with a deep notch.
Females. Face more convex than in males. Apterous. Subgenital plate very short and transverse; distal margin straight in examined material. Ovipositor long, thin and straight; valves very little widened before apex; dorsal valves finely crenulated distally.
DISTRIBUTION. — Endemic to New Caledonia. Up to now, Orintia was mentioned from New Caledonia without precision ( Gorochov 1986a; Otte et al. 1987). It is reported here for the first time from Mont Panié, Aoupinié, Col d’Amieu, Pic du Grand Kaori, Pic d’Amoa, Pic du Pin, Mont Dzumac, Mont Koghis and Parc des Grandes Fougères (material in MNHN collection).
HABITAT. — Orintia specimens have been found in rainforest by day in the leaf litter or under bark. Others were foraging by day on the dense moss covering dead fallen trees (LDG, pers. Obs.).
REMARKS
Gorochov (1986a) described this genus in the Lissotrachelini (Pentacentrinae) . Otte et al. (1987) tentatively transfered it to the Thetellini (Nemobiinae) . Morphological and genitalic characters show that Orintia belongs to Nemobiinae , althouth it is not clear in which tribe.
Orintia has been described on one female only. Male characters are described here for the first time.
Orintia cornuta Desutter-Grandcolas , n. sp. ( Figs 6 View FIG , 7 View FIG , 8A View FIG ; Table 2)
TYPE LOCALITY. — New Caledonia, Grande Terre, Mont Panié, Wewec, 20°35’41.80”S, 164°43’42.37”E.
ETYMOLOGY. — Species named after the pair of long horns present on male face.
TYPE MATERIAL. — Holotype. New Caledonia, Grande Terre, Mont Panié, Wewec, 20°35’41.80”S, 164°43’42.37”E, 410 m, 1♂, 6-11.XI.2010, jour, fn 189, collected with a mouth aspirator, perched on an understorey structure, F. Legendre (MNHN-EO- ENSIF3964). Paratype. 1 ♂: Same locality, date and collector as holotype, 20°35.39’46”S, 164°43’40.40”E, 420m, 1♂, fn 215, collected by beating (MNHN-EO-ENSIF3965).
DIAGNOSIS. — Within the genus, O. cornuta Desutter-Grandcolas , n. sp. is characterized by the pair of long horns present on male face, the highly contrasting coloration of its head and pronotum (see below and Fig. 6B, C View FIG ), and the presence of only two apical spurs on TII. From the type species, Orintia incrustata (known by a female only), it can be recognized by the coloration of its head, with alternatively yellow and dark brown transverse stripes ( Fig. 6B View FIG ) and of its abdomen (tergites III, VIII and IX darker: Fig. 6A View FIG , to be compared with fig. 27 in Gorochov 1986a). Male genitalia with rectangular median distal lobes; lateral lobes only slightly coiled but with a deep lateral notch; ectophallic apodemes thick at base and not projecting beyond pseudepiphallic sclerite.
Female. Unknown.
HABITAT AND LIFE HISTORY TRAITS. — Unknown.
DESCRIPTION
In addition to the characters of the genus: Size medium.
Coloration ( Fig. 6 View FIG A-C)
Face ( Fig. 6D View FIG ) and cheeks ( Fig. 6C View FIG ) black; a light yellow line along the eyes outer margin; dorsally, a yellowish transverse band between eyes, running along distal margin of fastigium and turning around lateral ocelli; area around and behind ocelli black; head dorsum overwise yellowish, with a median brown fleck; scapes yellowish, with two ivory dots, one on dorsal side and one on inner margin; antennae yellowish basally, then black brown with a whitish article every 10 to 12 dark articles ( Fig. 6A View FIG ). Pronotum LL entirely dark brown; DD yellowish, with two pairs of dark brown dots, one along each margin. Legs yellowish, with incomplete black rings: TI, TII with two rings; FI, FII with one ring, plus one basal and one apical black dot on outer side;TIII with three black rings; tibial apex yellowish; FIII ( Fig. 6E View FIG ) with four black spots on dorsal side, more or less extended on inner and outer sides of FIII. Cerci light yellow.
Male
Face slightly concave along median part of epistemal suture. Under each antennal pit, area just above epistemal suture projecting as a long cylindrical and slightly curved horn ( Fig. 6 View FIG A-D); each horn thicker ventrally close to is base; both horns slightly convergent distally. Subgenital plate triangular ( Fig. 8E View FIG ); distal margin bisinuate with acute median part; black.
Male genitalia ( Fig. 7 View FIG )
Slightly convex on mid length, rectangular with a narrow distal part. Pseudepiphallic sclerite more sclerotized dorsally. Median apical lobes well-developed, rectangular with a longer outer angle; lobes only hardly separated with a distal margin making a very wide V. Lateral lobes well-separated from main pseudepiphallic part, dejected laterally; their distal margins somewhat coiled, with a deep median notch. Ectophallic apodemes short, not projecting beyond anterior margin of pseudepiphallic sclerite, and thick at their base.
Female
Unknown.
