Hainanaella lutea n. sp.

( Figs. 1–15 )

Type material. Holotype, male (macropterous): Jianfengling, Hainan Province, China, 18.v.1983, coll. Yalin Zhang. Paratype, 1 male (macropterous), same data as holotype ( NWAFU).

Description. Color. General color yellowish orange. Eyes black. Ocelli reddish black. Antennae with a blackish brown ring around apex of first segment, base of second segment with blackish brown maculation. Macropterous wings hyaline, light yellowish orange. Dorsum of male abdomen ornamented with irregular brown spots laterally, middorsum brown, venter with light brownish patches sublaterally. Male pygofer tan, paler dorsally. Parameres and median elongate process of anal segment blackish brown.

Structure. Body length of macropterous form in males 4.31–4.41, width at tegula 0.94–0.98. Head including eyes narrower than pronotum (0.95:1), vertex quadrate, longer medially (0.30–0.31) than wide (0.24– 0.25), anteriorly transverse, slightly produced medially, lateral carinae subparallel, in lateral view meeting lateral carinae of frons with obtuse angle at fastigium, basal compartment wider at base than greatest length about 1.8:1. Frons longer (0.63–0.66) than wide (0.28), lateral carinae concave between eyes, nearly parallel below ocelli, widest at level of ocelli. Postclypeus and anteclypeus with distinct median carinae, together approximately 0.8x length of frons, in profile shallowly convex, postclypeus as wide as frons at apex. Rostrum reaching beyond meso-trochanters. Antennae terete, surpassing frontoclypeal suture, segment I longer than wide about 1.8:1, segment II longer (0.31–0.33) than I (0.16–0.18). Pronotum in dorsal view shorter than vertex, lateral carinae of pronotum posterolaterally directed, slightly curved, not reaching posterior margin, pronotum width 0.83–0.85, length 0.15. Mesonotum length 0.63–0.66, lateral carinae not extending to posterior margin, median carina obscure apically. Forewing length 3.53–3.73, rounded at apex. Legs with tibia normal (not expanded), metatibia with two lateral spines, metabasitarsus (0.39–0.41) nearly as long as the tarsomere 2 (0.16–0.18) + 3 (0.19–0.22) combined, calcar (0.35–0.37) slightly shorter than metabasitarsus, thickly foliate, tectiform, with 34–39 small, black-tipped teeth on lateral margin.

Male genitalia. Pygofer with medioventral process single, lobe-like, broad at base and attenuating towards apex. Diaphragm of pygofer with dorsal margin incised medially. Parameres not reaching dorsal margin of diaphragm, apex narrowed and directed laterad, outer margins sinuate. Aedeagus tubular, in profile widening towards apex, with subapical tag reflected cephalad, its apex turned ventrad and pointed, its sub-apex with a short process, basal part with another short and stout process; in dorsal and dorsocaudal view aedeagus greatly compressed laterally, plate-like, with 3 processes, two of them at right and one left, phallotreme dorsad near apex. Opening for parameres with dorsal margin evenly arched upward, ventral margin sinuate. Arms of suspensorium symmetrical, shorter and narrower than stem. Anal segment ring-like, median elongate process bifurcate apically, each bifurcation with a dentate-like process subapically.

Female unknown.

Brachypterous form. Unknown.

Etymology. The name is derived from the Latin word “luteus” (brown) which refers to the general color of the type specimens.

Distribution. Known only from the type locality in southern China (Hainan Province).
