Genus Quatlocellus Yao, Cai & Ren , gen. nov.

Type species. Quatlocellus insolentis Yao, Cai & R en, sp. nov.

Diagnosis: Body elongate, lateral sides subparallel. Head large, width and length subequal, longer than pronotum, anteocular portion longer than postocular; eyes round, widely separated; antenna 4-segmented, longer than head and pronotum combined, first segment shortest, second longest and slender, fourth segment fusiform, thickest, shorter than third; rostrum slightly stout, arising from apex of head, short, extending to fore coxae, all segments subequal in thickness, first segment concealed between bucculae, subequal to third in length, second longest, fourth shorter than third, acute distally. Pronotum trapezoidal, length shorter than width, without collar; scutellum triangular, longer than pronotum at midline, wider than length; femora distinctly thicker and shorter than tibiae, fore and mid legs subequal in length, hind leg longer than mid leg, tarsus 3-segmented, tarsomeres subequal in thickness, first and second subequal in length, third longest; fore wing macropterous, venation of corium and clavus prominent, main veins form four cells, two large and two small, C present, connected with Sc at basal 1/4 of corium, forming a fused vein, C+Sc, this ending at apex of corium, Sc separating from Sc+R at basal 1/4 of corium, very short, Sc+R and Cu diverging at a single point at base of fore wing, and forming a large cell, a cross vein near corium-membrane boundary joined with C+Sc, R, M, and Cu, forming three cells, outside cell largest; 2A along hind margin of clavus, ending at apex, clavus quite large, forming claval commissure. Abdomen oval, ovipositor very long, not projecting beyond last paratergites, extending through last three abdominal segments.

Distribution. China.

Etymology: The generic name is a combination of the Latin quattuor (“four”) and locellus (cell).

Remarks: The new genus is closely related to Originicorizus gen. & sp. nov., but differs from the latter in the body length over 8 mm (vs. Originicorizus , less than 7 mm), rostrum short, not extending to mesocoxae (vs. extending to third abdominal sternite).
