Hecalus changjiaotus , sp. n.

( Figs 44–51 )

Type material. Holotype: ♂, CHINA : Hainan Province: Bawang Mountain , 10. xi. 2007, coll. Yani Duan ; Paratype: 1 ♂, Jiangsu Province: Yixing, Hufu , 30. ix. 1974, coll. Fasheng Li ( CAU) .

Description. Colour. Green or yellowish green. Frontoclypeus pale brown. Ocelli yellow, margined with red brown circle. Eyes red brown or brown with white stripe in the middle. Forewings transparent and veins pale in male. Hindwings hyaline, pale white.

Body. Length, male 5.3 mm to the tip of forewing. Vertex broadly triangular, rounded apically, little upturned anteriorly. Ocellus close to corresponding eye. Measurements of vertex length: interocular width: pronotal length (mm): 0.68: 0.88: 0.68.

Male genitalia: Subgenital plate with 6 setae laterally, sharply concave in the middle laterally. Pygofer side acutely angled apically. Aedeagus with pair of long terminal processes, curving caudodorsally; shaft expanded in the middle, slightly constricted at 2/3; anterior shaft ridged ventrally; gonopore apical; dorsal apodeme well developed.

Female: unknown.

Distribution: China (Hainan, Jiangsu).

Etymology. The species name, an adjective, is derived from the Chinese pronunciation of “long process”.

Remarks. This species resembles H. prasinus , but the latter is shorter in size with the aedeagal process longer, the anterior aedeagal shaft ridged ventrally and slightly constricted at 2/3 length, and the subgenital plate sharply concave in the middle laterally. It also resembles H. erectus but can be distinguished from the latter by the more slender aedeagal shaft, curved style apophysis, and longer and more setose pygofer.
