Abstract

A new genus and species of soft-winged flower beetles (Coleoptera, Malachiidae), Aliattalus intercalaris gen. et sp. nov., are described in the Late Eocene Baltic amber. The new genus is assigned to the tribe Palpattalini because the male possesses specific structures: an elongated, ventrally curved, domed pygidium with an elongated and bilaciniate apical sternite is combined with large palps, in which the second and third segments are closely adjacent to each other and enlarged. This species in appearance is similar to the genus Palpattalusinus Tshernyshev, 2020, also known in amber: both have similarly fused and enlarged palps with a small cup-shaped first segment, but the apical palpomere in the new species is curved inward and rounded at the apex, rather than elongated to form a tube.

波罗的海琥珀Soft的一种新属和种（甲翅目，蠕形科）

摘要

柔翅花甲虫的一个新属和种（拟翅目，Malachiidae），Aliattalus intercalaris属。等 11月，在始新世波罗的海琥珀中有所描述。新属被分配给Palpattalini部落，是因为其雄性具有特定的结构：一个细长的，腹侧弯曲的，圆顶状的gi虫，带有一个细长的和具回纹状的顶端的tern节，与大的鳞茎结合在一起，其中第二和第三部分彼此紧密相邻并扩大。该物种的外观类似于Palpattalusinus属 切尔尼雪夫（Tshernyshev），2020年，也以琥珀色闻名：两者都具有类似的融合和扩大的手掌，并带有小杯状的第一节，但新物种的顶手掌向内弯曲并在先端变圆，而不是拉长而形成管子。
