Species of small size, brownish, larger than Lebinthus villemantae sp. n. ; with a distinctive rounded area on the harp as in L. villemantae n. sp. and L. makilingus Otte, 2007 from which it differs by male genitalia, shorter female FWs and details of colouration. FIGURE 10. Male genitalia of: A–C, Lebinthus truncatipennis ; D–F, Lebinthus villemantae n. sp. ; in dorsal ( A, D ), ventral ( B, E ) and lateral ( C, F ) views. Scale bar: 1 mm. Redescription. In addition to the characters mentioned by Chopard (1929) : Colouration brown with more or less contrasted coloured patterns. Head dorsum yellowish with 4 wide brown longitudinal bands more or less distinct, and with a yellow band posterior to eye prolonging eye colouration and underlined ventrally by a black band. Eyes well protruding, black with a red brown dorsal longitudinal band. Fastigium wider than long, setose, brown with a dark spot behind yellowish median ocellus; apex yellow and slightly carenated posteriorly to median ocellus, at margin between front head and dorsum. Scapes yellowish brown with brown patterns on face; antennae light brown. Face yellowish brown with paired spots between scapes; 2 dark brown horizontal bands, one below scapes; 2 yellow spots dorsal to epistomal suture, and one on mandible bases and labrum; clypeus yellowish brown except ventral margin; cheeks yellowish brown except for a dark brown pattern posterior to eyes ( Fig. 3 F). Palpi yellowish brown, with one dark brown ring per segment. Pronotum: Dorsal disk slightly trapezoidal, slightly sinuate posteriorly; yellowish brown with few dark spots, slightly lighter on lateral margins. Lateral lobes black dorsally, ventral margin yellow with a faint curved brown pattern ( Fig. 3 F). Legs: Fore and median legs light brown, femora with dark brown spots, tibiae with dark rings. Hind femora orange brown, with striated dark patterns on outer faces, 3–5 black spots on each ventral edge, knees dark brown; hind tibiae with dark brown rings, distal half of tarsomeres III-1 and III-3 dark brown. Hind tibiae with 5–8 inner (m = 6.4, n = 7) and 8–12 outer (m = 9.7, n = 7) spines above spurs and 3– 5 inner (m = 4.8, n = 7) and 5–6 outer (m = 5.7, n = 7) spines between spurs. Tarsomeres III-1 with 2–3 spines on dorso-outer edges (m = 2.6, n = 7) and 0–1 (m = 0.7, n = 7) on outer faces. Abdomen homogeneously dark brown, with sometimes a median dark brown band ventrally. Cerci brown basally, yellowish brown with dark brown rings toward apex. Male : FW not reaching abdomen midlength. FW colouration: Cells and veins brown, not translucent; base of CuA and angle of 1A with a yellowish brown sclerotization; intermedian area yellowish brown; lateral field brown, its dorsal margin (MA/R area) dark brown. FW venation ( Fig. 1 F): 1A angle wide (>100°); stridulatory file with 223 teeth (n = 1), located on transverse part of 1A only. CuP visible at FW basis only. Harp wide, including a false mirror, i.e. a distinctive rounded area delimited by the strong harp vein, polyfurcated anteriorly, and fused with both diagonal vein and CuA posteriorly. Distal part of CuA weak and curved inwards, surrounding the median fold. Distal part of diagonal vein very weak. Longitudinal veins very strong at apex, transverse veins very weak. Mirror (d1) not differentiated. Apical field absent, with no bifurcation of CuA posterior to diagonal vein. Lateral field with 5 longitudinal veins including MA, R and 3 more ventral veins; latero-dorsal angle made by MP; R without strong bifurcating veins. Subgenital plate clog-shaped ( Fig. 4 F), less elongate than in L. villemantae ( Fig. 4 G). Male genitalia ( Fig. 10 A–C): Pseudepiphallic sclerite elongate, widened anteriorly, straight dorsally; posterior apex with short triangular lophi curved dorsally, setose, separated by a V-shaped indentation; anterior apex straight, its lateral margins slightly curved dorsally. Pseudepiphallic parameres trilobate, the posterior lobe dorsal, the two other lobes ventral. Ectophallic arc complete and narrow, well separate from basis of pseudepiphallic parameres. Ectophallic fold wide, with paired preapical sclerotization. Ectophallic apodemes wide, parallel and exceeding anterior margin of pseudepiphallus. Endophallic sclerite long, exceeding anterior margin of pseudepiphallus, its posterior apex with a median triangular expansion and with short lateral arms; endophallic apodeme made of a narrow median crest. Female: FW very short ( Fig. 6 C), not reaching posterior margin of second tergite, not overlapping; dorsal field with 6 strong brown longitudinal veins; yellowish brown sclerotization between brown transverse veins. Lateral field darker than dorsal field, with 4 strong dark brown longitudinal veins. Ovipositor shorter than hind femora; apex lanceolate, slightly denticulate on dorsal edge ( Fig. 7 C). Female genitalia: Copulatory papilla ( Fig. 8 G–I) very small, almost completely membranous. Juvenile: unknown. Measurements. see Table 1 . Habitat and life history traits. unknown. Behaviour. unknown.
