Specimens examined.

Holotype: 1 male, 22°28.26'N, 106°57.43'E, Nonggang Village, Longzhou County, Chongzuo City, Guangxi Province, 3 May 2014, coll. Ke-Liang Wu et De-Xing Liu. Allotype: 1 female, paratype: 1 male, 1 female, all speciemens were collected at the same place at the same time.

Diagnosis.

This species is similar to E. taiheizana Asahina, 1979, but can be distinguished as follows: 1) lateromedial margins of subgenital plate without processes, while with processes in E. taiheizana Asahina, 1979; 2) T1 was unspecialized, but T1 was specialized in E. taiheizana Asahina, 1979; 3) ventral margins of T9 without spines, but with 3 spines in E. taiheizana Asahina, 1979.

Description.

Male, pronotum: length × width: 5.2-6.0 × 6.0-6.5 mm; tegmen: 23.5 mm; overall length (including tegmen): 27.8-28.5 mm. Female, pronotum: length × width: 5.5-6.6 × 6.0-6.6 mm; tegmen: 23.4 mm; overall length (including tegmen): 27.8-29.5 mm.

Large size. Body dark brown, head extending beyond the pronotum, vertex tawny, ocellus yellow, face dark brown, interocular space is 3/4 of ocellus space, antenna base dark brown, a pair of symmetrical reddish-brown dots next to the antenna sockets, antenna sockets slightly wider than ocellus width. Pronotum approximate triangular, hind margin wide, dark brown. Tegmina and wings fully developed, tegmina extending beyond the end of abdomen; hind wing with radius vein branched near middle; medial vein simple; cubitus anterior vein with five complete and two incomplete branches, triangular apical area small. Anteroventral margin of front femur Type A3; the first tarsus of the hind leg longer than the sum of the rest tarsi; tarsal claws symmetrical and unspecialized, arolium and pulvillus present. The T1 unspecialized; T7 specialized with numerous hairs in the intermediate region (Fig. 22 ); right and left lateral plates of the T9 are similar, hind margins truncate, posterior corners rounder (Fig. 23 ). Male supra-anal plate symmetrical, middle of the hind margin concave (Fig. 24 ); subgenital plate asymmetrical, two styles on the left side of the hind margin, with some spines in the interstylar margin (Fig. 25 ); left aedeagus hook-shaped (Fig. 26 ); median aedeagus exposed, extending beyond the supra-anal plate, spicular (Fig. 27 ). Female similar to male; supra-anal plate and subgenital plate symmetrical, hind margin round, apex with small concavity (Figs 29 , 30 ).

Etymology.

Species name maxima refers to its large size, currently the largest species in Episymploce .
