Membranacea hubeiensis Yu & Yang sp. n. Figs 1-16

Description.

Length, male 4.1-4.3mm.

General color reddish to yellowish orange. Eyes dark. Ocellus on anterior margin of crown, light brownish. Coronal suture brown margined with cream and with a yellowish brown spot on each side (Fig. 1). Face orange, paler on gena; some specimens with brownish stripe on anteclypeus (Figs 2, 3). Pronotum reddish orange centrally and posteriorly, with a median yellowish patch at anterior margin (Fig. 1). Scutellum yellow with basolateral triangles black margined with reddish orange; apex and sometimes a stripe medially, black (Fig. 1). Forewing reddish orange, semi-transparent in basal 2/3 and yellowish, hyaline in apical 1/3. Abdomen brownish. Legs yellow except midlength of hind tibia, brownish.

Ventral male abdominal apodemes broad, reaching segment IV or V, margins parallel or slightly divergent (Fig. 7). Pygofer with dorsal margin strongly concave, apex finger-like with few microsetae; dorsal bridge less than one-third of total length of pygofer (Figs 8, 9). Subgenital plate broad, with an oblique line of ca. 14 macrosetae and ca. 40 microsetae in 4 irregular rows; outer margin slightly expanded at midlength and bearing five moderately long and stout setae forming the basal group (Fig. 10). Paramere narrowed from near midlength to apex, curved laterally with ca. 9 fine setae, apex with teeth and sensory pits (Fig. 14). Aedeagal shaft elongated, curved posteriorly, subapically with a flange on each side and a narrower flange each side of a single central spine on ventral surface (Figs 11, 12, 13); preatrium nearly half length of shaft (Figs 11, 13). Connective with base broad, apex narrow, apical margin deeply emarginate (Fig. 16).

Type material.

Holotype, male, Houhe Natural Reserve, Wufeng City, Hubei Province, 27 July 2010, coll. Xiaofei Yu. Paratypes: 22 males, same data as holotype.

Etymology.

The new species is named after its type locality: Hubei.

Remarks.

The new species is similar to Membranacea spinata Qin & Zhang, 2011, but can be distinguished from the latter by the different configuration of the aedeagal processes (compare Figs 11-13 with 17, 18) and by the more pointed apex of the male pygofer (Fig. 9).
