Andreas Floren, I.G. : 31.494] ( RBINS ) . Description. LT: ♂ : 9.6 mm . Head : vertex ( Fig. 1G ) elongate with apex rounded in dorsal view, lateral areas depressed between median carina and laterodiscal, obsolete carinae; median carina broader and medially excavated on basal half; vertex yellow-brown with lateral depressed areas black except small basal patch; apex black-brown; frons concave in lateral view ( Fig. 1H ); median carina extending to apex of clypeus ( Fig. 1I ); frons pale yellow-brown with 6 incomplete transeverse red bands; gena pale yellow-brown with black line at antero-dorsal angle; clypeus pale yellow-brown; labium reaching hind coxae; ratio LV/BV = 1.24; LF/BF = 1.75. Thorax : ( Fig. 1G ) pronotum with anterior and posterior margins emarginate; median carina grooved longitudinally; deeply impressed point on side of median carina; discal carinae curved; pale yellow-brown, darker, getting nearly black medio-anteriorly; mesonotum with median and discal carinae joining anteriorly; tegulae pale yellow-brown.

F. phallic complex, right lateral view. An : anal tube; Ae : aedeagus; G : gonostyli; Pe : periandrium; Py : pygofer. Scale 1 mm. Tegmina : ( Figs 1F,J ) elongate, subhyaline, pale yellow-brown with darker apical area and infuscate patches near base along costal margin, and at apex of clavus; veins slightly infuscate; veins at apical cells darker; 14–15 apical cells; 5 subapial cells; ratio LTg/BTg = 3.36. Hind wings : ( Fig. 1K ) hyaline with veins black; infuscate patches basally and at middle of sutural margin, at emargination; sutural margin strongly emarginate. Legs : piceous; femora III with longitudinal black line; tibiae III with 3 lateral and 6 apical spines; first hind tarsomere with 6 apical spines. Male genitalia : pygofer narrow with dorsal half broader; posterior margin strongly sinuate in lateral view ( Fig. 2A ); anal tube elongate and narrow, slightly curved postero-ventrad; in dorsal view, right half of apex projecting postero-ventrad ( Fig. 2C ); gonostyli elongate with ventral margin concave and apex roundly pointed in lateral view ( Fig. 2A ); dorsal margin with one digitiform process and two hooks at middle ( Figs 2A, B ); aedeagus with 3 strong processes: one on left side, projecting anteriorly, strongly curved, with hook dorsally near its base and teeth on dorsal margin and at apex of ventral margin ( Fig. 2D ); distal one on right side furcate, with dorsal part more developed and showing teeth on dorsal margin ( Fig. 2E ); proximal one on right side large, with ventral margin showing teeth and dorsal margin strongly sinuate, apex projecting dorsad ( Fig. 2E ); periandrium with ante-apical dorsal hook on left side and apical margin emarginate ventrally, pointed on left side and digitiform on right side ( Figs. 2D–F ). Biology. All twelve known specimens have been collected by canopy fogging, including eight collected during the night by that technique. This could indicate nocturnal habits for the species. Specimens were collected from the following species of tree: Barringtonia scortechinii King (Barringtoniaceae) ( 5 specimens ), Aporosa lagenocarpa Airy Shaw (Euphorbiaceae) (1), Aporosa maingayi Hook. f.( Euphorbiaceae ) (1), Aglaia cf. macrophyllum (Meliaceae) (3), Ficus leptogramma Corner (Moraceae) (1). According to those data the species seems polyphagous but only direct observations could confirm that it does not live on some species of epiphytes or vines. Note. the species is very close to S. robustocarina Liang & Wang, 2008 . The two species can be reliably separated by the shape of the male genitalia, especially the processes of the aedeagus as in the key couplet above.
