Remarks.

Up to now, there are eight known species in the genus Linnavuoriana . In Xinjiang and Yunnan provinces, we collected two known species that are the first records of the genus from China. A key to the Chinese species is given.

Diagnosis.

Body cream, light yellow (Figs 21 , 22 ). Crown and pronotum with symmetrical black round patches, and basal triangle black (Figs 25 , 26 ). Forewing semitransparent with light smoky brown or brown patches (Figs 21 , 22 , 29 , 30 ).

Head bluntly produced, little narrower than width of pronotum, and 1/3 times middle length of pronotum (Figs 25 , 26 ). Forewing slender and obtuse apically with both sides parallel; RP+ MP’ petiolate at base; 1st apical cell usually smallest; 2nd apical cell biggest. Hind wing with two cross veins far away from each other.

Abdominal apodemes well developed, often extending to 5th abdominal sternite.

Male genitalia. Hind margin of pygofer with inner ridge, several rigid microsetae near posterior-dorsal margin and numerous minute tubercles posteroventrally. Subgenital plate parallel-sided and lack macrosetae at base, narrowing from apical 1/3-1/2 of outer margin, rounded terminally, usually with row of rigid microsetae and some fine microsetae scattered on apex. Paramere rarely curved with subapical tooth; distally with row of microsetae on outer margin and row of sensorial pits on inner margin. Connective small with central ridge underdeveloped. Aedeagal shaft with a pair of triangular protrusions on dorsal surface laterally; gonopore apical.
