1. Haphsa acutipetala sp. n. ( Fig. 1 )

Material examined. Holotype: ♂ ( NWAFU), China: Mengla County, Yunnan Province, 2.v.2019, coll. Wang Wen- qian . Paratypes: 3♂♂ ( NWAFU), same data as holotype .

Measurements (in mm; n= 4♂♂). Body length: 31.3–32.6; fore wing length: 44.2–45.2; fore wing width: 13.3–13.9; width of head including eyes: 10.8–11.0; pronotum width (including pronotal collar): 12.3–12.8; mesonotum width: 10.3–10.6.

Etymology. The species name is a Latin feminine adjective meaning “oxypetalous”, signifying the shape of the opercula.

Description of male.

Head ( Fig. 1A, B ). Head about as wide as base of mesonotum, fuscous with the following black markings: central hourglass-like marking enclosing ocelli; pair of wide rectangular markings from the antennal substrates to the lateral ocellus; pair of spots extend to the posterior margin of the compound eyes. Compound eyes ochraceous, ocelli yellow. Postclypeus fairly prominent, light yellow, with apical half black. Anteclypeus black, with basal margin and small spot on disc ochraceous. Rostrum reaching to posterior coxae, light ochraceous with apex fuscous.

Thorax ( Fig. 1A, B ). Pronotum longer than head, generally ochraceous, disc with the following black markings: pair of central longitudinal fasciae, extending from anterior margin of pronotum to pronotal collar, curved outward and dilated both anteriorly and posteriorly; pair of obliquely longitudinal fasciae extending from paramedian fissures to lateral fissures and pair of fasciae along lateral fissure. Pronotal collar generally light brown with pair of black markings laterally. Mesonotum fundamentally light brown, with the following black markings: a medial longitudinal fascia dilated posteriorly; pair of fasciae along medial parapsidal suture; pair of small markings anteriorly between parapsidal sutures and lateral sigilla; a broad, interrupted fascia along each lateral sigilla and pair of large spots on scutal depressions. Cruciform elevation olivaceous-tawny with black markings on distal anterior arm. Legs mostly light brown with brown markings, fore femora with spindly primary spine, thick secondary spine and small subapical spine. Opercula tawny, long triangular, their medial edges diverging at the level of the posterior margin of sternite II, pointed apices extending to the posterior margin of sternite VI.

Wings ( Fig. 1A ). Hyaline, fore wing with fuscous spots at bases of second and third apical cells. Hind wing has no markings.

Abdomen ( Fig. 1A, B ). Fairly dark tawny, turbinate, longer than distance from head to cruciform elevation, sparsely covered with silver pile. Tergite 1 with black markings on posterior margin, tergites 2–8 with black markings on anterior margins. Lateral and posterior margin of the last few sections blackened. Timbal covers big, brown with silver pile.

Male genitalia ( Fig. 1C, D ). Pygofer elliptical in ventral view. Basal lobes of pygofer thin and long, curved inward. Median uncal lobes short, membranous and fused. Lateral uncal lobes slightly broad and developed, parallel to each other, slightly curved inward distally.

Distribution. China (Yunnan).

Remarks. This new species is similar to H. lueta in the body size and mesonotum markings, but it can be distinguished from the latter by the shape of the uncal lobes (lateral uncal lobes broad and developed, parallel to each other in H. acutipetala sp. n.; lateral uncal lobes long, gradually narrowed in H. lueta ) and the much longer opercula. This new species is also similar to H. nicomache in the length of opercula, i.e., both extending to the posterior margin of sternite VI, but it can be distinguished from the latter by the shape of opercula and the basal lobes of pygofer in male (basal lobes of pygofer thin, opercula with pointed apices in H. acutipetala sp. n.; basal lobes of pygofer broad, opercula with rounded apices in H. nicomache ).
