2. Parapelerinus emarginatus sp. nov. (Figs. 6–8, 20–21, 23, 25, 27, 29, 33, 35)

Holotype: male, at light, CHINA: Fujian Province: Wuyishan Mt., Wuyishan Nature Reserve, Sangang Reserve Station, 15.viii.2007, Coll. Ding Liang ( IZAS).

PLATE II, leg. Figs. 12, 14, 16, female of Parapelerinus ensatus sp. nov. (holotype); Figs. 13, 15, 17, female of Conversifastigia gressitti sp. nov. (holotype). Figs. 12, 13, anterior leg (including part of femur and tibia) in lateral view; Fig. 14, median femur in lateral view; Fig. 15, median leg (including part of femur and tibia) in lateral view; Fig. 16, posterior femur in lateral view; Fig. 17, posterior leg (including part of femur and tibia) in lateral view. (scale = 1 mm) Description: Male (holotype). Size slightly smaller than for typical phaneropterines. Pronotal disc with distinctive median transverse groove, V-shaped, and with an elongate middle stripe throughout; posterior margin of disc slightly emarginated; lateral lobe much higher than long, with anterior margin slightly concave, posterior margin widely rounded, and ventral margin obtusely angularly rounded (Figs. 6–8). Legs: Anterior femora armed with 5 spines on ventro-anterior margin; median femora with 4 spines on ventro-anterior margin; posterior femur with 9 anterior and 9 posterior ventral margins. Anterior tibiae without dorso-anterior spines; median tibiae with 2 dorso-internal spines; posterior tibiae with 24 internal and 24 external dorsal spines. Tegmen: radial vein also with one oblique branches after radial sector vein. Wings developed well. Tegmen extending beyond apex of hind femur, apex of tegmen rounded. Hind wing longer than tegmen. Stridulatory file cambered, with about 73 regularly sparsely arranged teeth, which are gradually becoming smaller from center towards both ends (Fig. 23). Right stridulatory area with distinct triangular mirror (Fig. 21). Tenth abdominal tergum with apical margin truncate. Epiproct broadly triangular, with lateral margin straight, apex obtuse. Cerci equably incurved, gradually tapering, apex with interior margin gradually contracted into a long spine (Fig. 25). Male subgenital plate elongate, groove-shaped; gradually constricted to distinctly notched apex (Fig. 35). Inner genitalia strongly sclerotized, split from apical third into two slightly face-to-face systematrical sclerites, which widened in middle, and apical part deflexed with spine-like apex (Figs. 27, 29).

Female unknown.

Color: Overall color deep green. Compound eyes brown. Basal portion of male stridulatory apparatus with a large ochreous spot, this spot present on the other tegmen as well. Sclerites of concealed genitalia and apex of male cerci brown.

PLATE III, stridulatory area of the genus Parapelerinus gen. nov.. Figs. 18, 19, 22, male of Parapelerinus ensatus sp. nov. (paratype from Bawangling Nature in Hainan Island); Figs. 20, 21, 23, male of Parapelerinus emarginatus sp. nov. (holotype); Figs. 18, 20, male stridulatory area on left tegmen; Figs. 19, 21, male stridulatory area on right tegmen; Figs, 22, 23, male stridulatory file on underside of left tegmen. (scale = 1 mm)

PLATE IV, male abdominal apex of the genus Parapelerinus gen. nov.. Figs. 24, 26, 28, male of Parapelerinus ensatus sp. nov. (paratype from Bawangling Nature in Hainan Island); Figs. 25, 27, 29, male of Parapelerinus emarginatus sp. nov. (holotype); Figs. 24, 25, male abdominal apex in dorsal view (as well as including apex of male cerci in enlarged view); Figs. 26, 27, male abdominal apex in lateral view; Figs. 28, 29, male internal genitalia in enlarged lateral view. (scale = 1 mm)

Measurements of male (mm): Length of body: 24.0; length of pronotum: 4.5; basal width of pronotum: 2.8; distal width of pronotum: 3.3; length of tegmen: 33.5; largest width of tegmen: 8.6; length of anterior femur: 5.5; length of anterior tibiae: 6.8; length of mid femur: 6.4; length of mid tibiae: 8.6; length of posterior femur: 18.9; length of posterior tibiae: 21.8.

Etymology: The new species is named for the distinct shape of male subgenital plate.

Discussion: P. emarginatus differs from the type species in the shape of the male cerci, the male concealed genitalia and the male subgenital plate. There are minor differencs in the shape of the lateral lobe of pronotum and the spots on the male stridulatory apparatus.

Distribution: China: Fujian Province.
