2. Alloteratura (Alloteratura) flabellata View in CoL sp. nov.
( Fig. 2 View FIGURE 2 )
Description. Male. Body small. Fastigium verticis conical, apex bluntly rounded. Eyes nearly globular, protruding forward.Apical segment of maxillary palpi shorter, about 1/3 length of subapical one, apex enlarged ( Fig. 2F View FIGURE 2 ). Anterior margin of pronotum nearly straight, posterior margin angularly rounded, lateral lobe longer than high; humeral sinus distinct. Thoracic foramen large, oval, exposed ( Fig. 2D View FIGURE 2 ).
Tegmina long, surpassing apices of postfemora, anterior and posterior margins nearly parallel, apices angularly rounded. Hind wings slightly longer than tegmina.
All femora without spines on ventral surface, apices of genicular lobes of all femora obtusely rounded. Procoxae with one short spine, protibiae with 5 spines on internal margin and 4 spines on external margin of ventral surface while apical spines much shorter than subapical spines; tibial tympana open on both sides and oval. Mesotibiae with 2 long spines on internal margin and 4 long spines on external margin of ventral surface. Posttibiae with 27–33 spines on internal and external margins of dorsal surface separately, bearing 2 pairs of dorsal apical spurs and 1 pair of ventral apical spurs.
Tenth abdominal tergite longer, with a longitudinal sulcus in the midline, the middle area of posterior margin with a concavity ( Fig. 2I View FIGURE 2 ). Basal half of cercus thick, upcurved in the middle, inner margin slightly concave, and then a lamellate lobe expanded directed internally; apical area conical, and apices of cerci obtusely rounded ( Fig. 2 View FIGURE 2 G–I). Epiphallus thick, horsehead-shaped in lateral view, with a longitudinal groove on ventro-apical surface; and a longitudinal groove on dorso-apical surface too, the posterior margin extended backward and slightly bent ventrad, apex spreading outward, approximately fan-shaped ( Fig. 2C View FIGURE 2 ). Subgenital plate nearly triangular, with a longitudinal groove in the midline, posterior area rectangular and slightly produced in the middle; styli long, inserted on subapical areas of lateral margins of subgenital plate, conical, apices bluntly rounded, directing ventrally ( Fig. 2 E View FIGURE 2 ).
Colouration. Body yellowish green (green when alive). Eyes light brown. Disc of pronotum with a pair of longitudinally yellow stripes. Spines of legs black brown, tarsus green. Tegmina and the exposed parts of hind wings green.
Female. Unknown.
Material examined. Holotype: ♂, Mangshan, Yizhang , Hunan, 23 August, 2018, coll. Yarui Xin.
Measurements (mm). Body: ♂ 11.5; pronotum: ♂ 3.5; tegmina: ♂ 13.6; postfemora: ♂ 9.3.
Distribution. China (Hunan).
Discussion. The new species slightly resembles Alloteratura plauta Jin, 1995 , but differs from the latter in: male cerci upcurved in the middle, inner margin with a lamellate lobe expanded; epiphallus thick, horsehead-shaped in lateral view.
Etymology. The name of new species is derived from apical morphology of epiphallus, Latin flagell- means fan-shaped.
