Chagria camptoprocessa sp. nov.

(Figs. 1–3, 12–30)

Description. Ground color brownish. Eyes blackish, coronal suture darkened basally, vertex with two large black patches on the anterior margin, and their surrounding areas sordid whitish (Fig. 1). Face with frontoclypeal area and anteclypeus ochre-yellow, lorae light brown, genae sordid whitish (Fig. 3). Pronotum brown, somewhat ochrered medially and along posterior margin. Basal triangles black; scutoscutellar sulcus dark, deeply incised. Fore wing whitish-brown, semitransparent, brochosome field ochre-yellow (Fig. 1).

Abdominal apodemes reaching posterior margin of 4th sternite (Fig. 14).

Pygofer side well sclerotized at basal half and lower basal angle, caudal part of lobe with spiny sculpture (Fig. 15); pygofer dorsal appendage small (Fig. 17), connected with semi-ring and ligments (Fig. 16). Subgenital plate with apical part twisted laterad, with several rigid microsetae distally, subbasal part with fewer and smaller peg-like setae than those of the C. sikkimensis (Figs. 19, 20); style broadened subapically, with some sensory pits subapically (Figs. 21–23). Connective as in C. sikkimensis, but with longer manubrium (Figs. 24, 25). Aedeagal shaft as in C. sikkimensis, but basal processes a little longer and apical part curved laterad (Figs. 27–29).

Measurement. Male length 3.3–3.4mm (including wing).

Material examined. Holotype: 3, CHINA, Yunnan Prov., Jinghong, Bubeng, at light, 4 September 2010, coll. Zhang Meng; Paratypes: 23, same data as holotype.

Diagnosis. This new species is extremely similar to C. sikkimensis, but lacks the two blackish spots mesad of basal triangles (Fig. 1); apex of subgenital plate twisted not cephalad but laterad (Fig. 19); subgenital plate with fewer and smaller peg-like microsetae subbasally (Fig. 20); style with distinctly broader subapical part and central part (Figs. 21, 22); connective with obviously longer manubrium (Figs. 24, 25); aedeagal basal processes with broader base when viewed in profile (Fig. 26), curved laterad apically, total length slightly greater (Figs. 27–29).

Discussion. Differences between C. camptoprocessa and C. sikkimensis are slight, but stable. Usually the setosity of the subgenital plate, shape of the style and connective, and shape and length of the aedeagal processes are stable at specific level in Erythroneurini, and may therefore be used for species discrimination. Specimens from Bubeng are nearly invariant in the characters listed above, and these distinguish C. camptoprocessa from the type species. The differences in the connective and aedeagal processes are particularly distinctive.

Etymology. The specific epithet is derived from Latin prefix “campto-” and Latin noun “processa” which refers to the bent basal processes of aedeagus.
