H. ocampoi Bai et Zhang sp. nov. ( Fig. 1 )

Holotype: female, a nearly complete specimen (No. BU-001785); the piece of amber containing the specimen was ground and polished to a 19.5×9.8× 9.1 mm cube (0.85 g in weight). The type specimen, currently housed in the Institute of Zoology, Chinese Academy of Sciences ( IZAS), will be eventually deposited in the Three Gorges Entomological Museum , Chongqing (specimen available for study by contacting MB or WWZ).

Diagnosis: This species could be classified into Hybosorinae by a combination of the following characters: antennae with lamellate club, mandible produced beyond apex of labrum, outer margin of protibia with three teeth, preapical surfaces of mesotibia without transverse or oblique ridges or combs, mesocoxal cavities at middle narrowly separated, and abdomen five-segmented.

Etymology: This species is named in honor of Dr. Federico C. Ocampo in recognition of his extraordinary contribution to the research of Hybosoridae .
