description: Hengchunia hexaproducta sp. nov.
Figs. 22–30
Description. Body stramineous. Head and thorax with two longitudinal brown bands dorsally. Eyes brown. Vertex and pronotum pale-yellow. Scutellum yellownish, transverse impression distinct. Dorsal surface of abdomen yellowish, ventral surface dark brown medially. Apex of forewings brown. Legs dark brown.
Head anteriorly triangularly produced, longer than width between eyes, wider than pronotum (Fig.22). Clypellus similar in width throughout length. Eyes fairly large, ocelli on anterior margin, separated from corresponding eye by approximately their own diameter. Antennae arising near lower corner of eye. Pronotum with sides short, anterior margin strongly and roundly produced, posterior margin slightly concave. Scutellum triangular, its length slightly shorter than length of pronotum, with transverse suture curved and depressed. Forewings with four apical cells and two subapical cells, outer subapical cell absent, appendix very small.
Male genitalia. Pygophore slightly longer than high, posterior pygophore lobe elongate with many large setae medially, without processes (Fig.23). Valve large, subtriangular (Fig.24). Subgenital plate short and broad, distally concave; a heavily sclerotized dentate area dorsoapically, toothed area separated in an apical (Fig.26); a uniseriate row of macrosetae along ventrolateral margin, many fine setae ventrally along posterior margin to anterior margin (Figs.25, 26). Aedeagal shaft elongate, slightly curved dorsad; anterodorsally with three pairs of spiniform processes apically; two short spines medially just basad of midlength on anterior surface; gonopore apical; preatrium elongate with a pair of long and slender processes arising from ventral margin, directed dorsally (Figs.27, 28). Style apical process elongate with a subapical lobe, apical margin serrate; lateral lobe well developed with a group of small setae (Fig.29). Connective loop-shaped, stem absent (Fig.30).
Measurement. Length (including tegmen): 3, 2.9–3.0mm.
Host. Grasses.
Type material. Holotype 3, China: Henan Prov., Luanchuan County, Heyu, 19 August 2008, coll. Jichun Xing (GUGC). Paratypes: 23, same data as holotype.
Diagnosis. This species is similar to Hengchunia truncata Dai & Zhang, but can be distinguished from the latter by the aedeagal shaft medially on the dorsal side with two short spines and with three pairs of spinose processes apically, and the subgenital plate distally concave.
Etymology. The species name is derived from the Latin words “ hexa- ”and “ producta ”, indicating apex of the aedeagus with six spinose processes.
Discussion. The genus Hengchunia contains 12 described species: 8 in the Oriental Region, 2 in the Afrotropical Region, 1 in the southwestern Palearctic Region, and 1 in the southeastern Palearctic. Three species were previously recorded from China (Oriental Region). Here, the distribution of this genus is extended to the southeastern Palaearctic Region.
