Penthimia fulviventris Walker 1851: 841 .

Balala fulviventris (Walker) : Distant 1908: 251; Jacobi 1914: 380; Schmidt 1920a: 118; Jacobi 1944: 35; Evans 1946: 46, 59; Metcalf 1962: 14.

Wania membracioidea Liu 1939: 297 .

Balala membracioidea (Liu) : China 1941: 255; Synonymised by Liang, 1995: 210.

Length (including forewing): ♂ 12.35 mm.

External morphology. Body dark brownish-red. Crown ( Fig. 1A ) anterior margin round, length moderately shorter than 1/2 width between eyes. Exposed part of mesonotum and scutellum ( Figs. 1A, B ) reaching apex of clavus, exposed part of mesonotum about 1/7 scutellum long, scutellum moderately swollen and gradually declining toward apex, median longitudinal ridge very strong and extended through entire scutellum. Forewing with one transparent band present between apical cells and appendix. Hind femur with 5 macrosetae at apex, tibia with ca. 10, 10 setae in rows AD, PD, respectively.

Male genitalia. Pygofer ( Figs. 1 D–F) with dorsal inner margin nearly straight, pair of strong acute teeth present on subapex of ventral margin, pointing to each other; ventral appendage with base not very broad, reaching apex of pygofer, terminal slightly curved backward. Subgenital plate nearly as long as pygofer side. Apical margin ( Figs. 1 G, H ) of connective slightly wavy; style about 1.5x connective long; aedeagus shaft tubular without any accessory, preatrium about as long as shaft, gonopore subapical on shaft ventral surface.

Material examined. 1♂ (Holotype): ‘ Penthimia fulviventris .’ ‘Type’ ‘360’ ‘NHMUK 010592183’ ( BMNH) .

Distribution. Borneo, China, India (Assam, Madras), Indonesia (Sumatra), Myanmar.

Remarks. We checked the male specimen (MIZPAS) from Tonkin identified as B. fulviventris by Schmidt ( Schmidt, 1920a) but it should be B. lui according to the genitalia. So we delete the distributional record in Tonkin from B. fulviventris and add Tonkin to B. lui .
