摘  要：
本文记述跳(虫甲)亚科(Alticinae,Chrysomelidae)的新属Omeisphaera,系以新种O.anticata为模式种,产于四川峨眉山。模式标本保存在中国科学院北京动物研究所。 峨眉球跳(虫甲)Omeisphaera新属 本新属与Sphaeroderma Stephen及Argopus Fischer两属最接近,外形更酷似Argopus属的种类,但唇基正常(图3),不若该属种类之向前叉开而分为两叶。它的主要区别特征在于后胸腹板的前部,即介于中足基节之间的部分显著隆起,向前突出,与前胸腹板相遇,遮盖了中胸腹板(图4);前突的端末钝圆,不具边框。在Sphaeroderma、Argopus等属,后胸腹板前部并不隆起,端末具边框,与中胸腹板嵌合,处于同一水平。

General colour red-brown, the middle and apical portions of each elytron more yellowish; head and anterior half of prothorax shining black; anterior legs with the apical 2/3 of tibia and one or two basal segments of tarsi blackish; antennae black, opaque, except the three basal segments shining piceous, the first partly yellow beneath and the last more or less brownish towards apex.Head impunctate, frontal tubercles slightly oblique, interantennal space narrow, raised. Antennae extending back to the middle of elytra, second and third segments equal in length. Pronotum very finely and moderately closely punctate, the anterior angles slightly produced and lobiform. Elytral punctures fine, but much coarser than those on pronotum, arranged in rather irregular rows.Length : 5-6 mm. Breadth: 3.8-4.3 mm.Szechwan: Omeishan, 1,000-1,800 m, June 23-26, 1955, 2(?).
