Abstract
A highly distinctive genus of pselaphine tribe Batrisini, Feabatrus gen. nov., is described based on Leonardo Fea’s historical collection housed in the Museo Civico di Storia Naturale “G. Doria” di Genova, Italy. The genus includes two new species from Myanmar, F. myanmarensis sp. nov. and F. leonardoi sp. nov. Feabatrus gen. nov. is characterized and can be separated from related genera by large-sized body with long, suberect setae on the dorsal surface and antennae, pronotum with large marginal, discal and antebasal spines, elytra with a smooth disc and shallow discal striae, inner two basal foveae close, and lacking subhumeral fovea, distinct constriction between the elytra and the abdomen, and the female possessing an asymmetric genital complex as well as a flat, sub-trapezoidal tergite 5 (VIII) that has a small nodule in the middle of the posterior margin. A single female from Yunnan, southwestern China, representing a third species, is briefly described but left unnamed.
这是一种非常独特的凤仙花属Batrisini，名为Feabatrus gen. nov.，它是根据莱昂纳多·菲亚(Leonardo Fea)收藏的历史藏品描述的，这些藏品收藏于巴黎自然故事博物馆(Museo Civico di Storia Naturale)。Doria " di Genova，意大利。该属包括缅甸新种F. myanmarensis sp. 11和F. leonardoi sp. 11 . 11 . Feabatrus gen. 11 .的特征是:体型大，背部表面有长而近直立的刚毛和触角，前额有大的边缘、盘状和前基棘，鞘翅有光滑的圆盘和浅的圆盘纹，内侧两个基部中央窝紧密，没有肱骨下中央窝，鞘翅与腹部之间明显的缩窄。雌性具有不对称的生殖复合体和扁平的、亚梯形的土体5 (VIII)，其后缘中间有一个小结节。来自中国西南部云南的一只雌性，代表着第三个物种，被简要地描述了一下，但没有命名。
