Type species.

Bambusimukaria quinquepunctata sp. n., here designated.

Diagnosis.

Crown with anterior and submarginal carinae; entire second segment of antenna visible from above. Frontoclypeus transversely impressed across base beneath prominent overhanging anterior edge of head. Forewing with four apical cells, venation obscure except near apex, vein M3+4 originating from junction of inner and central anteapical cell. Hind wing with four closed apical cells. Ventral margin of male pygofer without process. Style with short articulating arm and broad outer basal arm. Connective Y-shaped, fused with aedeagus. Aedeagus with paired stout shafts diverging from base, gonopores subapical, large; basal apodeme short.

Description.

Head and thorax. Crown (Figs 4, 7) shorter than pronotum, subconically anteriorly rounded, more than half as long as breadth between eyes, with anterior and submarginal carinae, posterior end of anterior carina strongly incurved before eyes; disk strongly sloping posteriorly, texture smooth; ocelli on crown, distant from eyes and close to anterior margin; entire second segment of antenna visible from above; eyes long, oblique, extending backward over anterior angles of pronotum; face (Fig. 5) including eyes as long as broad, frontoclypeus transversely impressed across base beneath prominent overhanging anterior edge of head, narrowed towards clypeus; clypellus narrowing apically; lorum broad. Pronotum (Figs 4, 7) elevated centrally, arched, anterior margin convexly rounded between eyes, posterior margin slightly concave, lateral margin short. Scutellum (Figs 4, 7) large, broad, basal margin longer than lateral margin, transverse depression slightly curving. Forewing (Figs 1-3, 9) elongate, considerably longer than abdomen, slightly widened posteriorly, with four apical cells, venation obscure except near apex, vein M3+4 originating from junction of inner and central anteapical cell; appendix well developed. Hind wing (Fig. 10) with four closed apical cells. Profemur (Fig. 11) with 2 dorsoapical setae, row AM with 1 stout seta, and row AV with several fine setae. Protibia (Fig. 11) with 4 macrosetae in row AD and with 13 macrosetae approximately equal in length in row AV. Hind femur broadened distally and slightly bowed; apical setal formula 2+2+1. Hind tibia flattened and nearly straight, with PD setae very long, alternating in length and with 1 smaller setae between macrosetae; row AD with 14 macrosetae interspersed by 1 to 2 small stout setae; several supernumeral setae present between AD and AV rows. Metabasitarsomere with 3 platellae and 2 setae on apical transverse row, and one row of 6 stout setae at middle and one row of 4 stout setae at lateral margin.

Male genitalia. Male pygofer (Figs 15, 16) rather dorso-ventrally depressed, with macrosetae caudally; ventral margin without process. Valve (Fig. 19) broad, subtriangular. Subgenital plate (Fig. 19) very short, broad basally, with group of moderately long fine setae laterobasally and few short fine setae apically. Style (Fig. 20) with short articulating arm and broad outer basal arm. Connective (Fig. 21) Y-shaped, fused with aedeagus. Aedeagus (Figs 21-23) with paired stout shafts diverging from base, gonopores subapical, large; basal apodeme short, thumb-like in lateral view.

Female genitalia. Sternite VII (Fig. 12) with hind margin broadly concave. Pygofer with numerous macrosetae. Ovipositor protruding slightly beyond pygofer apex. First valvula (Fig. 13a, b) weakly curved; dorsal sculpturing pattern strigate, reaching dorsal margin; without distinctly delimited ventroapical sculpturing. Second valvula (Fig. 14a, b) broad, widest near mid-length, thereafter gradually tapered to acute apex; with broad dorsal sclerotized area, thereafter dorsal margin with numerous fine regular teeth after dorsal prominences.

Host plant.

Bamboo (Figs 24-27).

Distribution.

Southwest and south China.

Etymology.

The genus name, which is feminine, is a combination of “bambus” (bamboo) and " Mukaria " (name of the type genus of Mukariini ), meaning that members of this genus feeding exclusively on bamboo ( Bambusoideae).

Remarks.

The new genus can be distinguished from other genera of Mukariini by the very large anal tube process (see also above key to genera of Mukariini ). Among other Chinese mukariin genera, the new genus is somewhat similar to Flatfronta Chen & Li, 1997 and Tiaobeinia Chen & Li, 2008 in the shape of head, and also similar to Mukaria Distant, 1908 in the shape of male genitalia. See also Table 1 for further comparisons.
