Diagnosis

Anaplecta arcuata Deng & Che sp. nov. resembles A. corneola Deng & Che sp. nov., but can be distinguished from it by the following characters: 1) L2vm slender with brush-like bone sheet in the former, simple sheet-like in the latter; 2) L3 with apex of uncinate part sharp in the former, enlarged and blunt in the latter. The right phallomere was not seen when examining the species, we are not sure whether it is degenerated or missing is uncertain and needs to be checked in future examinations.

Etymology

The specific name is derived from the Latin word ‘ arcuatus ’, meaning that the brush-like bone sheet (L2vm) looks like a bent bow-like arcuate structure.

MEASUREMENTS (mm). Male: pronotum length × width: 1.4–1.6× 1.6–2.2, tegmina length: 5.1–5.4, overall length: 6.4–7.4. Female: pronotum length ×width: 1.3 ×1.8, tegmina length: 4.7, overall length: 6.3.

COLORATION. Body yellowish brown, eyes black, antennae dark brown ( Fig. 4 A–B). Head yellowish brown ( Fig. 4C ). Pronotum and tegmina yellowish brown, lateral borders of pronotum nearly hyaline ( Fig. 4D, G ). Wings with costal field and appendicular field infuscated, other part pale yellow, with veins brown ( Fig. 4H ). Abdominal sterna, legs and cerci pale yellow ( Fig. 4B, I ).

HEAD AND THORAX. Interocular space greater than distance between antennal sockets ( Fig. 4C ). Third, fourth and fifth maxillary palpi subequal in length, fifth maxillary palpus thicker than fourth, which is nearly triangular ( Fig. 4E ). Pronotum subparabolic ( Fig. 4D ). Tegminal with veins distinct; wings with radial veins slightly indistinct, CuA ending at CuP ( Fig. 4 G–H). Front femur type B2 ( Fig. 4F ). Pulvilli absent, arolia present.

MALE ABDOMEN AND GENITALIA. Supra-anal plate with paraprocts almost identical, simple sheet-like ( Fig. 4I ). Subgenital plate nearly symmetrical, semi-oval; styli with length about ¼ of interstylar space, interstylar margin arcuate ( Fig. 4J ). Phallomere simple, L1 small triangle with long, slender and curved filamentary structure, L2v broad, L2vm slender with brush-like bone sheet, L2d simple sheet-like, L3 robust, uncinate part with apex sharp; right phallomere degraded or absent ( Fig. 4 K–L).
