Brachypsectridae in SYNOPSIS OF THE DESCRIBED COLEOPTERA OF THE WORLD

Vernacular names
English: Texas beetles
русский: Брахипсектриды

The Brachypsectridae are a family of beetles commonly known as the Texas beetles.[1] There are only two extant genera, Brachypsectra and Asiopsectra. The type species, Brachypsectra fulva (LeConte, 1874), occurs in North America. Other species in the genus have a cosmopolitan distribution. Two other extant and fossil species have been described from the Dominican Republic.[2] While formerly considered monogeneric, in 2016 Asiopsectra was described from specimens found in Iran and Tajikistan.[3] Two extinct genera, Vetubrachypsectra and Hongipsectra, known from adults, and a larval genus, Cretopsectra are known from Cenomanian aged Burmese amber.[4][5][6]

Taxonomy

The family is somewhat enigmatic since the discovery and description of the first species, Brachypsectra fulva. This was originally included in the family Dascillidae, but was later placed in the new family Brachypsectridae by Horn (1881).[7]
Description

Members of this family are small (4–8 mm), flattened, relatively soft-bodied, brown or yellow beetles with large eyes. The elytra are indistinctly striated and the antennae form a club.[8]

The larvae are distinctive being described by Gordon Floyd Ferris in 1927 and Blair in 1930 as being "entomological enigmas". They were not associated with the adult beetles until 25 years after their discovery by Barber in 1905. They are ovate and flattened and have moderately long, lateral lobes lined with elongated feathery lobules on all the thoracic segments and the first eight abdominal segments. The head and the posterior abdominal segments are relatively small and dark-coloured.[8]
