New fossil rhopalids (Heteroptera: Coreoidea) from the Middle Jurassic of Inner Mongolia, China Author Yao, Yunzhi Author Cai, Wanzhi Author Ren, Dong Author Shih, Chungkun text Zootaxa 2006 1384 41 58 journal article 10.5281/zenodo.175076 e7401681-2883-43bc-a922-497842c67a97 1175-5326 175076 Genus Grandicaputus Yao, Cai & Ren , gen. nov. Type species: Grandicaputus bipunctatus Yao, Cai & Ren , sp. nov. Diagnosis: Body moderately sized, elongate, general body plan resembling lygaeids’, dorsal surface densely punctate. Head large, wider than long, slightly shorter than pronotum, apex surpassing first antennal segment, clypeus distinctly surpassing mandibular plates; antenna 4-segmented, longer than half of body, first segment short and thick, second and third segments slender, second longest, fourth fusiform, shorter than third; eyes moderately large, round and prominent, interocular space distinctly wider than eye diameter. Pronotum trapezoidal, slightly transverse, without collar; femora distinctly thicker than tibiae, fore and mid legs subequal in length, hind leg longer than mid leg, tibia longer than femur, with densely setae, tarsus 3-segmented, subequal in thickness, first tarsomere feebly shorter than second, third longest; hemelytron macropterous, long and narrow, apical margin rounded, reaching tip of abdomen, with distinct embolium, corium slightly elongated on costal margin; with claval commissure; membrane with nearly 20 longitudinal veins distally.

Scale bar = 1 mm. Distribution. China . Etymology: The name is a combination of the Latin grandis (“large”) and caput (“head”’), referreing to the remarkably large head. Remarks: This new genus can be placed next to Miracorizus Yao, Cai & Ren, 2006 , as both are similar in the following characters: dorsum densely punctate; antenna long and slender, the first segment shortest, not extending beyond head apex, fourth segment fusiform; tibia longer than femur, with dense setae; hemelytron macropterous, with thick embolium. But Grandicaputus gen. nov. can be easily distinguished from Miracorizus by its head wider than its length (vs. width and length subequal), clypeus distinctly surpassing mandibular plates (vs. mandibular plates not surpassing clypeus), pronotum without collar (vs. with distinct collar), and with claval commissure (vs. without claval commissure).

Scale bar = 1 mm. The new genus is also similar to Longiclavula Yao, Cai & Ren, 2006 in antenna long and slender, same ratio of antennal segments; hemelytron macropterous, with thick embolium, membrane with nearly 20 longitudinal veins. But the new genus can be distinguished from the latter by dorsum densely punctate (vs. dorsal surface smooth), pronotum without collar (vs. with distinctly collar), with claval commissure (vs. without claval commissure).
