Kameruloria gabonensis Desutter-Grandcolas , n. sp.

( Figs 5 B, H, J, 6D–F)

Type locality. Gabon, Makandé, affluent Offoué, Bees forest, 11°55'E 0°41'S, 220m.

Type material. Holotype. Gabon, Makandé, affluent Offoué, forêt des abeilles, 11°55'E 0°41'S, 220m, 1 male, 28.vi.1994, nuit, fn84, molecular sample LDG 455, sur plante (L. Desutter-Grandcolas), MNHN-EO-ENSIF3718.

Etymology. Species named after its place of origin.

Diagnosis. Among the Phaloriinae , species fitting the emended diagnosis of Kameruloria for the following characters: tympana shape and development; TI almost not inflated at tympana level; TIII with relatively short subapical spurs, the inner ones slightly longer toward TIII apex and well shorter than dorsal inner apical spur; male FW venation (mirror and harp veins); male subgenital plate (apical margin faintly sinuate); male genitalia (pseudepiphallus membranous with a pair of sclerotized, disto lateral processes, pseudepiphallic parameres spinelike, ectophallic fold wide and short, ectophallic dorsal valves not developed, endophallic apodeme made of a high median longitudinal crest and a pair of lateral lamellae along endophallic sclerite). K. gabonensis Desutter- Grandcolas, n. sp. is most similar to K. nigricornis Desutter-Grandcolas , n. sp. by the length of male FWs, with a well-developed apical field, the relative size of maxillary palpi joints (joint 3 longer than joint 4), and male genitalia, including the widely extended ventral margins of ectophallic fold. It differs from that species by its coloration (antennae black in K. nigricornis Desutter-Grandcolas , n. sp.), number of stridulatory teeth in males, and details of male genitalia. Female unknown.

Description

In addition to the characters of the subfamily and genus. Species with longer FWs than K. primitiva , at least in males; HWs going slightly beyond FWs. Many very short setae.

Head. Fastigium as wide as the scapes, the distance between the lateral ocelli only slightly less than the distance between one lateral and the median ocelli. Joint 4 of maxillary palpi little shorter than joint 3; joint 5 much longer than joint 3, more than in K. trimaculata Desutter-Grandcolas , n. sp. (compare Fig. 5 B and 5C). Pronotum very transverse; DD anterior margin concave, posterior margin bisinuate. TI hardly inflated at the level of the tympana; outer tympana bigger than the inner one, located in a shallow groove. TIII subapical spurs short, the inner ones longer than the outer ones; inner spurs regularly longer toward TIII apex, outer spurs about equal in size; first inner subapical spur the longest, more than half the length of inner dorsal apical spur; this last spur longer than basitarsomeres III. TIII serrulation lacking between first subapical spurs and apical spurs, and between subapical spurs; above subapical spurs, outer spines: seven to eight (mean 7.5) in male; inner spines: six to seven (mean 6.5) in male. Basitarsomeres III serrulation: no inner spine in addition to apical one; 3 outer spines in male.

Coloration. Head dorsum yellowish with four thin longitudinal brown lines, and a faint wider one behind the eyes; fastigium brown dorsally, ocelli ivory. Cheeks brown with a rounded yellow spot connected to a yellow line between the eye and subgenal suture. Face and clypeus brown with several yellow spots. Antennae yellowish brown, scapes with a slightly darker spot on their inner margins. Palpi light yellowish. DD brown with anterior and posterior margins light; muscular inscriptions and part of DD posterior half yellowish; LL brown, lower margin widely bordered with yellowish even along anterior and posterior margins, the distal margin black brown. Legs light yellowish, spotted and annulated with dark brown: FI, FII with a brown distal ring, several dark spots on outer side and a wider one on inner side; TI, TII with four rings, darker dorsally; FIII outer side with a distal ring, plus brown striae less regular than in K. trimaculata Desutter-Grandcolas , n. sp.; FIII inner side with two transverse bands and additional spots toward the base. Basitarsomeres brown at base and apex, yellow otherwise. TIII spurs yellowish on basal half length, brown on median length, and distally yellow with dark apex.

Male. Metanotum and tergites without glandular structures. FW with many small setae; venation as in K. nigricornis Desutter-Grandcolas , n. sp.; harp with nine oblique, parallel veins, mirror wider than long, diagonal forked relative to the file only; apical field with six cell alignments. Stridulatory file with about 185 teeth. Apical field with five long cell alignments. Supra anal plate not elongate, with long, but without strong setae. Subgenital plate not very high, inflated laterally, distal margin hardly sinuate ( Fig. 5 H).

Male genitalia. Upper part of pseudepiphallus transverse and very narrow, with a short median, triangular distal process ( Fig. 6 D). Lower part of pseudepiphallic sclerite short, connected laterally to the rami; with two long distal processes ( Fig. 6 D) bifurcated posteriorly to midlength, with blunt apex with two small spines ( Fig. 5 J); pseudepiphallic parameres spine-like ( Fig. 6 D, F). Ectophallic apodemes thick, regularly curved, not raised dorsally, as long as the rami; arc sclerotized ( Fig. 6 D). Ectophallic fold wide, very short, sclerotized; ventral margins greatly extended ( Fig. 6 E, F). Endophallic sclerite long and very wide ( Fig. 6 E). Endophallic apodeme with a long longitudinal median crest, and a pair of long, short lamellas laterally to endophallic sclerite ( Fig. 6 D). Ectophallic dorsal valves lacking or very short.

Female. Unknown.
