Abstract

Elektroberotha groehni gen. et sp. nov. (Neuroptera: Berothidae) is described from Baltic amber. The genus is assigned to Berothinae based on female terminalia that have the following characteristics: long hypocaudae on gonocoxite 9; sternite 7 that is medially divided into a pair of lateral sclerites; and gonocoxite 8 with a medial process that is very similar to that of some extant berothine genera. The new genus is the first described fossil genus of the subfamily Berothinae. It is noteworthy for the possession of a fully-developed CuP in the hind wing, a vein that is strongly reduced in all other species of the subfamily. The genus Spiroberotha is considered to belong to the Berothinae.

摘要

格氏电贝罗（Elektroberotha groehni）属及种为新属新种（脉翅目：贝罗科），由波罗的海琥珀标本描述而来。基于雌性外生殖器的以下特征，该属被归入贝罗亚科：第9生殖基节上有长的尾下叶；第7腹片在中部被分为一对外侧骨片；第8生殖基节有一个内侧突，与一些现存的贝罗亚科属非常相似。该新属是贝罗亚科中首个被描述的化石属。值得注意的是，其后翅拥有完全发育的CuP脉，而在该亚科的所有其他物种中，这条脉都大幅退化。螺旋贝罗属（Spiroberotha）被认为属于贝罗亚科。
