Limassolla bicruralis Huang & Zhang sp. nov.

( Figs 1, 6, 11, 16 , 21–28 )

Body and face yellowish, eyes grey ( Figs 1, 11 ). Crown with cream patches at coronal suture and anterior margin ( Fig. 6 ). Pronotum with 5 long oval patches cream, remainder orange. Scutellum yellowish, basal triangles and apex orange. ( Figs 1, 6 ). Forewing with numerous small spots dark brown; 3 patches on clavus orange; claval suture bordered laterally with orange ( Figs 1, 16 ).

Abdominal apodemes extending to posterior margin of 5th sternite ( Fig. 21 ).

Male genitalia: Pygofer side rounded with ventral process extended dorsad, not surpassing dorsal margin of lobe; several rigid microsetae on disc ( Fig. 22 ). Subgenital plate with row of macrosetae gradually shorter from base to subapex ( Figs 23, 26 ). Paramere long and slender with two rows of microsetae on outer margin, portion distad of preapical heel relatively long ( Figs 24, 26 ). Connective with median anterior lobe well developed ( Figs 25, 26 ). Aedeagus elongate, slender with pair of short finger-like processes apically, basal apodeme bifurcate in posterior view. Gonopore apical ( Figs 27, 28 ).

Specimens examined. Holotype: ♂, China, Yunnan Prov., Sanchahe , 7.vi.1991, coll. Rungang Tian. Paratypes: 6♂ & 4♀, same data as holotype .

Measurement. Male, 3.4–3.5mm (including wing).

Etymology. The specific name is derived from the Latin prefix “bi-” and Latin word “cruralis”, referring to aedeagus with a pair of short processes apically.

Notes. This new species belongs to the Limassolla dispunctata group and resembles L. kakii Chou et Ma, 1981 in male genitalia, but differs in the predominantly yellowish coloration (dark brown in L. kakii ), in the forewing with 3 orange patches on clavus (a big yellowish patch in L. kakii ) and in having a rounded pygofer side and straight pygofer ventral process.
