Parasogata gen. n., a new genus of the tribe Delphacini with descriptions of two new species from China (Hemiptera, Fulgoromorpha, Delphacidae).

A new planthopper genus Parasogata gen. n. (Delphacidae: Delphacinae: Delphacini) was described and illustrated with two new species P.binaria sp. n. and P.furca sp. n. from south China. A key to species of the new genus is also given.

Here, a new genus, Parasogata gen. n., with two new species, P. binaria sp. n. and P. furca sp. n., are described and illustrated from China. The new genus is assigned to the Delphacini because the spinal formula of the hind leg 5-7-4, tibial spur large, thin, flattened and bearing a row of fine, black-tipped teeth on the posterior margin; genital diaphragm developed, suspensorium present. The similarities and affinities of the new genus with similar genera are compared and discussed. A key to the species of the new genus is also provided.

Materials and methods
Terminology of morphological and measurements follow Yang and Yang (1986) and the morphological terminology of female genitalia follows Bourgoin (1993). Measurements of body length equal the distance between the apex of vertex and tip of tegmen. All measurements are in millimeters (mm). Dry specimens were used for the description and illustration. Color pictures for adult habitus were obtained by KEYENCE VHX-1000. External morphology was observed under a stereoscopic microscope Leica Mz 12.5 and characters were measured with an ocular micrometer. The genital segments of the examined specimens were macerated in 10% KOH and drawn from preparations in glycerin jelly using Olympus CX41 and Leica MZ 12.5 stereomicroscope. Illustrations were scanned with Canon CanoScan LiDE 200 and imported into Adobe Photoshop 6.0 for labeling and plate composition.
The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, Guizhou Province, China (GUGC).
Diagnosis. This genus is readily recognized by its large size and vertex, pronotum and mesonotum bearing an uninterrupted white fascia. The genus is most similar to Sogata Distant, 1906 but separately by the phallus being up-curved (down-curved in Sogata (Ding 2006: figs 281-283)), with a row processes at subapically (without process in Sogata).
Etymology. This generic name "Parasogata" refers to its strong similarity to Sogata. The name is to be treated as feminine.
Diagnosis. Big-sized species with general color yellowish white to yellowish brown, anal segment with two pairs of spinose processes; aedeagus with ten processes subapically and with irregular teeth on ventral side of apex, constriction and bluntly rounded at apex (Fig. 26).
Report hosts. None.

Parasogata furca
Diagnosis. Big-sized species with General color yellow, anal segment with a pair of spinose processes, forked apically (Figs 50-51); aedeagus with eight processes and with many irregularity ventral teeth at subapically (Fig. 52).
Report hosts. None. Distribution. China (Guizhou, Yunnan). Etymology. The specific epithet is from the Latin word furca (forked), indicating the anal segment produced lateroapical angles forked.
Remarks. This species is similar to Parasogata binaria sp. n., but can be distinguished by the anal segment with a single pair of processes (two pairs of processes in Parasogata binaria sp. n.), suspensorium with dorsal margin hunch-up (with dorsal margin concave in Parasogata binaria sp. n.).
