Abstract

A new species of fossil cockroach, , is described from mid-Cretaceous Burmese amber. The new species is assigned to the family Corydiidae based on the following combination of characters: pronotum with tubercles, tegmina obovate with smallish anal region and spinules on the antero-ventral margin of the front femur (type C1). The new species is the second reported cockroach with ramified antennae. This finding broadens the diversity of Blattodea in mid-Cretaceous Burmese amber and provides further evidence of convergent evolution for antennal structures among different insect lineages.

摘要

一种新的化石蟑螂物种—— ，是从白垩纪中期的缅甸琥珀中描述出来的。基于以下特征组合，该新物种被归入穴螽科：前胸背板有瘤，翅革质倒卵形，肛区较小，前足股节前腹缘有小刺（C1型）。该新物种是第二个被报道的具分枝触角的蟑螂。这一发现拓宽了白垩纪中期缅甸琥珀中蜚蠊目的多样性，并为不同昆虫类群触角结构的趋同进化提供了进一步的证据。
