Kameruloria trimaculata Desutter-Grandcolas , n. sp.

( Figs 5 C, E, 6G–I, 7B, E–G)

Type locality. Congo, Parc national d'Odzala, Mbomo.

Type material. Holotype. Congo, Parc national d'Odzala, Mbomo, vii.1995, 1 male, savane arbustive, avancées forestières clairsemées à Marantaceae, M. Colyn rec., MNHN-EO-ENSIF3716. Allotype. Same data as the holotype, 1 female, MNHN-EO-ENSIF3717.

Etymology. Species named after the coloration pattern of its face, with three yellow spots.

Diagnosis. Within the genus, species characterized by the following characters: FWs short in both male and female, just going beyond abdomen tip, HWs lacking. Male. FWs narrow, with truncate apical field ( Fig. 5 E); stridulatory file with 195 teeth, widely apart over nearly the whole file length; mirror about as long as wide; subgenital plate well developed, high, with deeply emarginate distal margin and long distal angles long; supra anal plate without strong setae. Male genitalia: Pseudepiphallic distal processes very short, triangular; ectophallic fold entirely sclerotized, short, wide, and truncated apically, its distal margin almost straight; ectophallic apodemes very short and raised dorsally, the arc incomplete ( Fig. 6 G); endophallic sclerite long and thin; endophallic apodeme very long and very wide, supporting the development of long and thin ectophallic dorsal valves ( Fig. 6 G–I). Female. Subgenital plate distal margin bisinuate ( Fig. 7 B). Ovipositor shorter than TIII. Female genitalia: Copulatory papilla having the shape of a large though very thin sclerite, with a basal membranous cylinder ( Fig. 7 E–G).

Description

In addition to the characters of the subfamily and genus. Thin species with narrow and short FWs in males and females; highly setose. HWs not going beyond FWs.

Head. Fastigium narrower than the scapes, the distance between the lateral ocelli less than the distance between one lateral and the median ocelli. Joint 4 of maxillary palpi hardly shorter than joint 3 ( Fig. 5 C). Pronotum very transverse; DD anterior margin concave, posterior margin convex. 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 longer toward TIII apex, outer spurs shorter toward TIII apex; first inner subapical spur the longest, reaching about 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, siw outer spines in male and female; inner spines: one in male, four to five (mean 4,5) in female. Basitarsomeres III serrulation: no inner spine in addition to apical one; outer spines: four to six (mean five) in male and five in female.

Coloration. Head dorsum yellowish with four thin longitudinal brown lines, and a faint wider one behind the eyes; fastigium brown dorsally, ocelli ivory. Cheeks dark brown, except for a yellow triangular area under the eye. Face and clypeus brown with several yellow spots: a short one under the median ocellus, a longer, elongate one running from below the latter spot to the labrum, and a wide, ellipsoid one under each antennal pit. Antennae light brown; scapes with a wide brown spot on their inner margins. Palpi light yellowish. DD brown with anterior and posterior margins light, the posterior margin widely bordered with yellowish; the muscular inscriptions and four round spots posterior to inscriptions yellowish; LL brown, lower margin widely bordered with yellowish except along anterior and posterior margins, brown. Legs light yellowish, annulated with dark brown: FI, FII with two rings in distal half and an outer spot in basal half; TI, TII with four rings; FIII with two distal rings, plus brown striae on outer side, and two transverse bands on inner side. Basitarsomeres brown at base and apex, yellow otherwise. TIII spurs brown on basal half length, yellow distally with dark apex.

Male. Metanotum and tergites without glandular structures. FW very pubescent; venation as on Fig. 5 E: harp with nine oblique, parallel veins; stridulatory file with 195, well separate teeth; apical field with four short cell alignments. Supra anal plate wider than long, without strong setae. Subgenital plate well developped; distal margin deeply indented.

Male genitalia. Upper part of pseudepiphallus transverse and very narrow, with a median, triangular distal process ( Fig. 6 G). Lower part of pseudepiphallic sclerite short, membranous in median part, connected laterally to very long rami; with two short distal processes, triangular in shape ( Fig. 6 G); pseudepiphallic parameres lacking. Ectophallic apodemes thick and short ( Fig. 6 G), raised almost vertically ( Fig. 6 I); arc not fully sclerotized ( Fig. 6 G). Ectophallic fold wide, very short, sclerotized, without extended margins ( Fig. 6 H, I). Endophallic sclerite long and very wide ( Fig. 6 H). Endophallic apodeme with a long longitudinal median crest, and a pair of long, short lamellas laterally to endophallic sclerite ( Fig. 6 G). Ectophallic dorsal valves very long and thin, running along the whole endophallic sclerite and going well beyong pseudepiphallus ( Fig. 6 G–I).

Female. FW venation with few, strong longitudinal veins; CuA very high on more than half ot its length basally, MP very high on the median third of its length. Subgenital plate wider than long; distal margin bisinuate. Ovipositor shorter than FIII and TIII.

Female genitalia. Copulatory papilla very large, but as a long and flat sclerite, convex over its whole length, with a basal membranous cylinder ( Fig. 7 E–G); distal margin bisinuate.
