Abstract
Simple SummaryAs the largest group of organisms, Coleoptera includes more than 200 families worldwide; only 148 families have been recorded in China. Teredidae is a small family within Coccinelloidea, which has a cosmopolitan distribution, but has never been recorded in China. Until now, Teredus Dejean was endemic to Europe and North Africa. Here, we describe Teredus chinensis sp. nov. from central China, representing the first record of Teredidae in China and the first Teredus outside Europe and North Africa. This discovery not only enhances the Coleopteran diversity of China, but also largely extends the distribution of Teredus.Teredus Dejean is a genus of the poorly known family Teredidae, which, historically, includes only two species, restricted to Europe and North Africa. Teredus chinensis sp. nov. is here described, representing the first member of Teredidae found in China, which significantly extends the distribution of Teredus to East Asia. The diagnostic characters and information about the wood boring beetles associated with the new species are provided.
Highlights
Teredidae is a small and poorly studied family of Coccinelloidea, consisting of 10 genera and about 160 extant species distributed worldwide—except for South America and Antarctica [1,2], with Anommatus duodecimstriatus (Müller) having been recently introduced to South America [3]
The adults and larvae of this family are commonly found under bark and in the galleries of wood boring beetles and were proposed to be mycophagous [4,5,6]; the members of Anommatinnae are usually collected from leaf litter or soil and their biology is unknown [1]
The loose antennal club and externally closed procoxal cavities can assign the new species to the genus Teredus, while the paired long setae on the elytra have never
Summary
Teredidae is a small and poorly studied family of Coccinelloidea, consisting of 10 genera and about 160 extant species distributed worldwide—except for South America and Antarctica [1,2], with Anommatus duodecimstriatus (Müller) having been recently introduced to South America [3]. Teredus Dejean is a small genus of Teredidae which only includes two species, T. cylindricus (Olivier, 1790) and T. opacus Habelmann, 1854, restricted to Europe and North Africa. It can be distinguished from other genera within the family by the externally closed procoxal cavities. Though Bothrideridae was recognized as an independent family based on larval and adult characters [10,11], it was not widely accepted by other researchers. Lawrence [12] discussed the family status of Bothrideridae and later formally proposed it [5], a proposition accepted by many researchers [1,6,13,14].
