Rubmacula gen. nov.

Type species: Rubmacula lvchunensis sp. nov.

Description. Body yellowish-white with orange-red and brownish markings.Vertex yellowish with one red transverse arcuate band. Eyes yellowish-brown, ocelli yellowish white. Pronotum brownish-gray with one red transverse arcuate band. Face yellowish-brown, with one black-brown transverse band on anterior margin. Forewings are yellowish-brown and with red stripes. Hindwings macropterous. Legs brown.

Body robust. Head including eyes wider than pronotum. Vertex with fore margin produced roundly, median length shorter than width between eyes. Eyes large. Ocelli on anterior margin. Frontoclypeus distinctly longer than wide, anteclypeus expanded apically. Clypellus flat, slightly widened apically. Lorum broad, semicircular, width equal to that of clypellus, lower margin extended close to lower genal margin. Antennae at midhight of eye. Pronotum with anterior margin roundly produced and posterior margin concave, lateral margin carinate and slightly shorter than eye. Scutellum triangular, slightly shorter than pronotum, with transverse suture depressed. Forewing with four apical cells and three subapical cells, about 4 times as long as wide, the outer anteapical cell extended to costal margin and tapered to a point apically, claval veins fused, appendix small. Hindwing with three apical cells and two anteapical cells. Profemur with 2 dorsoapical setae, row AM with 1 stout seta, row IC with 13 setae, and row AV with several short setae in basal half. Fore tibia with 3 macrosetae in row AD and numerous macrosetae in row AV. Hind femur broadened distally and slightly bowed, apical setal formula 2+2+1. Hind tibia flattened and nearly straight, row PD with 21 macrosetae decreasing in length toward base; row AD with approximately 10 long stout setae and 1–4 shorter stout setae between each long seta; metabasitarsomere with four platellae and two setae on apical transverse row.

Male genitalia. Pygofer side longer than height, with numerous macrosetae. Valve subtriangular. Subgenital plate with wide base, sharply narrowed posteriorly; apex long, narrow, and digitate; lateral margin with a few macrosetae. Aedeagal shaft curved, slender, aedeagus with a pair of long processes fused to base, gonopore apical. Connective Y-shaped, articulated with aedeagus. Style with basal half wider and narrowing to the middle, apical half narrow.

Female genitalia. Female pygofer with ventroposterior margin slightly incurved. First valvulae with obscure reticulate sculpture dorsally and scale-like sculpture ventrally. Second valvulae with some distal teeth.

Remarks. The new genus can be distinguished from other genera of the Scaphoideini by the crown with orange-reddish band, forewings with reddish transverse bands, and aedeagus with pair of long basal processes.

Etymology. The generic name is derived from the Latin prefix “ rub- ” (red) with “ macula ”, referring to the body and forewings with reddish transverse bands.

Distribution. Oriental Region ( China).
