description: Fuscmacula gen. nov.
Type species: Fuscmacula biprocessa sp. nov.
Description. Body yellowish-brown. Eyes dark brown, ocelli brown. Pronotum with anterior yellowish-brown and posterior brown. Face yellowish-brown, with irregular black stripes. Forewing yellowish. Legs yellowishbrown, with symmetrical black markings or without; dark markings more extensive in male than in female.
Body robust, over 6 mm in length. Head including eyes as wide as pronotum. Crown with a large brown speck, much shorter medially than width between eyes, anterior margin roundly produced. Eyes large, Ocelli on anterior margin, separated from corresponding eye by approximately their own diameter. Face slightly flattened, its width narrower than length. Anteclypeus slightly expanded apically. Pronotum slightly shorter than wide, anterior margin strongly and roundly produced, posterior margin slightly concave. Scutellum triangular, shorter than median length of pronotum, with transverse suture depressed. Forewing with four apical cells and three subapical cells, about 4 times as long as wide, appendix small, one or more extra crossveins present preapically. Hindwing with three apical cells and two anteapical cells. Profemur with 2 dorsoapical setae, row AM with 1 stout seta, intercalary row with 10 setae, and row AV with 1 stout seta and several short setae in basal half. Hind femur broadened distally and slightly bowed, apical setal formula 2+2+1. Hind tibia flattened and nearly straight, row PD with 17 long macrosetae; row AD with approximately 12 long stout setae and 0-5 shorter stout setae between each long seta; metabasitarsomere with four platellae and two setae on apical transverse row.
Male genitalia. Male pygofer side longer than high, with numerous macrosetae on posterior margin. Valve subtriangular. Subgenital plate with wide base, long, triangular, sharply narrowed posteriorly, with 10 macrosetae at outer margin. Aedeagus with preatrium bearing pair of processes and a pair of broadleaf-shaped phragma lobes each with about 5 distinct short, stout setae; shaft curved, slender, U-shaped in lateral view, gonopore apical. Connective Y-shaped, articulated with aedeagus, anterior arms parallel. Style broad at base, abruptly narrowing subapically, preapical lobe prominent.
Female genitalia. Female with seventh sternite basally transversely rectangular. Female pygofer slightly incurved and ovipositor of the female very long. First valvula of ovipositor narrowly blade-like with sculpture strigate. Second valvula narrow with a somewhat elongate rounded lobe basally, without dorsal teeth.
Remarks. The new genus resembles Bambusana Anufriev, 1969 in general appearance, but can be distinguished by the aedeagus with preatrium bearing pair of processes and a pair of phragma lobes with distinct short, stout setae.
Etymology. The generic name is derived from the Latin words “ fusc- ” and “ macula ”, referring to the pronotum with two small symmetrical black spots and forewing with a large number of black spots.
Distribution. Oriental Region (China).
