Diagnostic characters

(1) disc of hind wings light white-bluish ( Fig. 3A View Figs 1–3. — 1 ); (2) small-sized (less than 22 mm long); (3) tegmina brown with dark red-brown band ( Fig. 3A View Figs 1–3. — 1 ); (4) head, pro- and mesonotum brown ( Fig. 3C–E View Figs 1–3. — 1 ).

Etymology

The species is dedicated to Prof. Thierry Bourgoin (MNHN), in acknowledgement of his permanent help and support from the beginning of the work of the author.

Paratypes

MADAGASCAR: 1 ♂, [Madagascar Est, Massif du Marojejy (rés. nat. intégr. 12) 1300m, 2/ 8-XII- 1972, A. Peyrieras] [Museum Paris] ( RBINS); 1 ♂, [Coll. P. Bleuzen, Lakato, Madagascar, 13.I.1962], 19°11’ S, 48°26’ E ( MHNL).

Description

LT: ♂ (n = 2) 19.2 mm (19.0–19.5).

HEAD. Yellow-brown sometimes suffused with red ( Fig. 3C–E View Figs 1–3. — 1 ); vertex with hind margin and sides strongly carinate ( Fig. 3C View Figs 1–3. — 1 ); sides of vertex bisinuate in lateral view ( Fig. 3D View Figs 1–3. — 1 ); frons with 2 carinae extending on sides of cephalic process ( Fig. 3E View Figs 1–3. — 1 ); cephalic process about 1.5 times as long as diameter of eye, projecting dorsad to posterodorsad ( Fig. 3D View Figs 1–3. — 1 ); apical half carinate anteriorly and strongly emarginate laterally ( Fig. 3E View Figs 1–3. — 1 ); posterior side of process with 2 longitudinal, sinuate carinae; lateral oblique carina between vertex and frons before eye ( Fig. 3D View Figs 1–3. — 1 ); postclypeus with sides strongly carinate and obsolete median carina; anteclypeus with strong median carina ( Fig. 3E View Figs 1–3. — 1 ); labium very elongate, surpassing hind coxae but not reaching apex of abdomen.

THORAX. Yellow-brown varied with irregular paler spots ( Fig. 3C–D View Figs 1–3. — 1 ); pronotum carinate anteriorly; sinuate carinae at anterior margin of disc, reaching anterior margin before median carina ( Fig. 3C View Figs 1–3. — 1 ); median carina strong, sinuate in lateral view; hind margin strongly elevated above level of mesonotum medially ( Fig. 3D View Figs 1–3. — 1 ); impressed point on disc on each side of carina; obsolete tubercles at each side of disc ( Fig. 3C View Figs 1–3. — 1 ); sides of prothorax longitudinally carinate; lateral lobes of pronotum rounded posteriorly ( Fig. 3D–E View Figs 1–3. — 1 ); mesonotum with median carina stopped at scutellum posteriorly; strongly sinuate carina on each side of disc, Y-shaped anteriorly; scutellum transversely wrinkled ( Fig. 3C View Figs 1–3. — 1 ).

TEGMINA ( Fig. 3A View Figs 1–3. — 1 ). Pale yellow-brown with irregular brown-black markings; ground colour red-brown on middle; clavus paler; white marking along sutural margin at level of nodal line; costal margin slightly rounded; apical angles rounded; sutural and apical margins sinuate, the latter oblique; ratio LTg/BTg = 2.6.

HINDWINGS ( Fig. 3A View Figs 1–3. — 1 ). Black-brown with large, light white-buish discal patch of basal half, reaching costal margin and extending posteriorly along vein Cu without reaching sutural margin; black-brown elongate marking basally along vein M; big black spot along vein PCu followed by 1–2 smaller spots; apex rounded, sutural margin sinuate.

LEGS ( Fig. 3A View Figs 1–3. — 1 ). Elongate and slender; femora brown with 3–4 narrow, sinuate and often incomplete pale yellow rings; pro- and mesotibiae brown with 2 pale yellow rings; metatibiae brown with pale yellow markings at spines; pro- and mesotarsi black-brown; first metatarsomere pale yellow-brown on basal ⅔; rest of metatarsi brown; metatibiae with 6–7 lateral and 7 apical spines; first metatarsomere with 9 apicoventral spines.

ABDOMEN ( Fig. 3A View Figs 1–3. — 1 ). Brown, darker ventrally.

Male genitalia

Dark brown ( Figs 17–18 View Figs 13–18 ); pygofer higher than long and with posterior margin nearly straight, slightly sinuate dorsally in lateral view ( Fig. 17 View Figs 13–18 ); anal tube elongate, 1.6 times longer than broad at apex and with lateral margins bisinuate in dorsal view ( Fig. 18 View Figs 13–18 ), slightly curved ventrally and with apex broadly rounded in lateral view ( Fig. 17 View Figs 13–18 ); gonostyli elongate, 1.6 times longer than high (dorsal process included), surpassing apex of anal tube and broadly rounded at apex in lateral view ( Fig. 17 View Figs 13–18 ); ventral margin straight, with strong angle at basal 1/8 ( Fig. 17 View Figs 13–18 ); dorsal margin with basal slender digitiform process projecting laterodorsally, pointed tooth laterally at middle of process projecting anteroventrally, apex of digitiform process narrowing apically ( Fig. 17 View Figs 13–18 ); apical ⅔ of dorsal margin sinuate ( Fig. 17 View Figs 13–18 ).

Remarks

Belbina bourgoini sp. nov. can be separated (1) from all species of the B. falleni + group by the brown colour of the genitalia, the more slender basodorsal digitiform process on the gonostyli and by having the gonostyli rounded at the apex, with the dorsal margin sinuate after the process; (2) from B. bergrothi , B. foliacea , B. madagascariensis and B. nympha by the basodorsal digitiform process on the gonostyli; (3) from B. servillei by having the digitiform basodorsal process of the gonostyli slender and narrow, not laminate.
