Zachobiella hainanensis Banks View in CoL Figs 4, 11-14
Zachobiella hainanensis Banks, 1939: 467.
Diagnosis.
Forewing pale yellow and hyaline, brown stripes present along the gradate series and from the middle of MA to the lateral margin, triangular dark spots absent at the forks of longitudinal veins and 3ir1 present after the fork of orb2. Male: dorsal surface of 8th tergite protruding upwards as a short rod; dorsal of 9th tergite slightly depressed and posteroventral edge extending upwards as a strong spine; dorsal of ectoproct obviously protruding upwards, posteroventral edge extending upwards into a thickened process. Female: 9th tergite very small, triangular from lateral view; ectoproct large, slightly depressed in the middle of the hind margin.
Measurements.
Forewing length 3.2-4.9 mm, width 1.2-1.4 mm. Hind wing length 3.5-4.2 mm, width 1.1-1.3 mm. Body length 2.8-4.3 mm.
Description.
Head. Yellowish-brown, without any dark areas. Antenna amber, more than fifty-five segments, more than a dozen of segments of distal flagellum obviously paler than the others. Eyes black with a metallic luster.
Thorax. Yellowish-brown. Brown longitudinal stripes present along both sides of the pronotum; scutum of mesonotum and metanotum obviously brown. Legs yellowish-brown with no spots.
Wings (Fig. 4). Forewing narrow, apex slightly tapered. Pale yellow and hyaline, thin brown strips present along the gradate series and from the middle of MA to the lateral margin; veins pale yellow and transparent with crossveins of gradate series brown. Anterior radial trace bearing two ORB’s, with two secondary branches respectively; 3ir1 present after the fork of orb2; 3ir2 present after the forks of orb1 and orb2. M forked into two branches, MA simple, MP forked into 4-5 branches. Cu with two branches. Three gradate series, inner gradate series with 2-3 crossveins; middle with two and the outer with four. Hind wing narrow, apex slightly tapered. Pale yellow, hyaline and immaculate; veins pale yellow and transparent. Rs forked in the middle with four branches. M forked into two branches, with 2-3 secondary branches respectively after the gradate series. Cu simple. One gradate series, with the only one crossvein r-m.
Abdomen. Yellowish-brown, tergites and sternites brown, darker than the arthropleuron, pilose. Male terminalia (Fig. 11). 8th tergite fused with the 8th sternite, dorsal of both 8th tergite protruding upwards as a short rod; posteroventral edge extending backwards as a stout spine, densely covered with long setae. Dorsal of 9th tergite slightly depressed and posteroventral edge extending upwards as a strong spine. Dorsal surface of ectoproct obviously protruding upwards and densely covered with long setae; posteroventral edge extending upwards into a thickened process, densely covered with setae on the inner surface. Mediuncus of gonarcus (Fig. 12-13) consisting of a pair of long curved hooks, three to four stout spines present on the surface with small spines around; extrahemigonarcus small and slightly tapered. Female terminalia (Fig. 14). 9th tergite very small, triangular from lateral view. Ectoproct large, slightly depressed in the middle of the hind margin. Subgenitale absent.
Distribution.
China (Hainan, Yunnan)
Material examined.
CHINA: 2♂2♀, Yunnan province, Dehong Autonomous Prefecture, Longchuan county. 28.iv.1981, Chikun Yang (CAU); 1♂, Yunnan province, Dehong Autonomous Prefecture, Ruili county. 1.v.1981, Fasheng Li (CAU); 1♂1♀, Hainan province, Wuzhishan city, Wuzhi hills. 16.v.2007, Yongjie Wang (CAU); 1♂, Hainan province, Baisha county, Yuanmen country, Hongxing village. 10.ix.2008, Xiushuai Yang (CAU).
Remarks.
This species was described by Banks (1939) based on one specimen from Hainan province. In this paper both male and female are described, including the genitalia, and the distribution records for this species in China are updated. This species is similar to Zachobiella striata but it can be easily distinguished by the different positions of 3ir1 in forewing.
