Sorineuchora viridis sp. n. Figs 8, 10A, 12 E–F

Type material.

Holotype male (IESWU), China, Hainan, Mt. Bawangling. 13 April 2016, light trapping, Jian-Yue Qiu leg. Paratypes (all from Hainan, deposited in MHBU). 1 male, Mt. Bawangling, 11-12 May 2007, Yi-Bin Ba and Jun-Tong Lang leg.; 3 males, Baisha, Nankai, 450m, 25-26 June 2008, Yi-Bin Ba and Jun-Tong Lang leg.

Diagnosis.

The color of the insects is green when they are alive (Fig. 10A), but it will become pale green or pale yellow when dried or kept in alcohol (Fig. 12 E–F); vertex with three dark spots and a dark transverse stripe (Fig. 8A); Tegmina with white dots on the veins (Figs 10A, 12E); appendicular field almost disappearing (Fig. 8D); L1 with black setae on the right apex (Fig. 8F); L2vm rod-like, connected with R3 by sclerite (Fig. 8G). Using these traits, the new species can be distinguished from its congeneric species.

Description.

Measurements (mm). Holotype, body length without cerci: 7.1; overall length including tegmen: 9.8; pronotum length × width: 2.0 × 3.1; tegmen length, 8.5. Paratypes, body length without cerci: 6.7-7.7; overall length including tegmen: 9.4-11.2; pronotum length × width: 2.35 × 3.05; tegmen length, 8.0-9.0.

Male. Body small, light green when alive (Fig. 10A), but it will turn pale yellow or pale green when dried or kept in alcohol (Fig. 12 E–F). The morphological description here is with the specimen dried.

Vertex with three dark spots, on the frons between the ocelli with a narrow dark transverse tripe (Fig. 8A). Maxillary palpi yellowish white, antennae yellow. Pronotum hyaline. Tegmina and wings hyaline. The former’s veins light with scattered white dots (Fig. 12 E–F). Abdomen and legs yellowish white.

Interocular space as wide as or slightly narrower than the space between antennal sockets. Fifth segment of maxillary palpus longer than the fourth. Pronotum subelliptical, anterior and posterior margins nearly truncate. Tegmina and wings fully developed extending beyond end of abdomen, the former with oblique CuA. Hind-wing R with oblique branches, M without branches, CuA with three branches, appendicular field almost disappearing. Front femur Type C2, pulvilli on four proximal tarsomeres, tarsal claws asymmetrical, arolia present. Abdominal terga unspecialized.

Supra-anal plate with hind margin rounded, paraprocts simple. Subgenital plate with subsymmetrical hind margin, a pair of styli with small setae, hind margin medially deflexed forming a short, longitudinal keel-like ridge, interstylar margin almost straight when flattened (Fig. 8E). L1 consisting of several irregular sclerites, the right apex with black setae (Fig. 8F); L2vm rod-like, connected with R3 whose apex has many setae by a sclerite (Fig. 8G); hooked phallomere (R2) on the right side, with a preapical incision.

Female. Unknown

Distribution.

China (Hainan).

Etymology.

Latin word viridis , meaning green, refers to the color of this species when alive.

Remarks.

Sorineuchora viridis sp. n. is similar to S. javanica (Caudell, 1927) in color (when faded) and subobsolete apical triangle. But S. viridis sp. n. differs from S. javanica in details of vertex, dots on the tegmina, and median and left phallomeres.
