Bledius annularis, or ringed borrow rove beetle, [1] is a species of spiny-legged rove beetle in the family Staphylinidae. [2] [3] [4] [5] It is found in North America. [3]

Contents

The lectotype for this taxon from a male specimen, collected from Lake Superior, and is housed within the Museum of Comparative Zoology at Harvard University. [6]

Habitat and distribution

Within New Brunswick, B. annularis is characteristically known to frequent damp clay riverbanks and shaded streams. [7]

A number of closely related species of Bledius are commonly grouped together and referred to as the "annularis complex", then further subdivided into the "annularis group". This 'complex' of difficult to distinguish species is distributed right across northern North America, and consists of B. annularis, B. breretoni, B. honestus, B. languidus, B.mysticus, B. nebulosus, B. sinuatus, B. stabilis, and B. washingtonensis. [8] :93

Description

The beetle is slender and elongate in appearance, measuring between 3.8 mm and 4.5 mm. Its head and thorax, as well as the tip of its abdomen are all black in colour, whilst the base of its abdomen, its elytra and its antennae are reddish-brown. Its legs are dark yellow. Its head is lightly granulate and also finely punctate. The thorax is not as wide as it is long, whilst the base of the abdomen is narrower than the elytra. The abdomen of this beetle sometimes appears slightly banded as a result of the hind margins of the upper (dorsal) segments being slightly darker in colour. [9]

<span class="mw-page-title-main">Rove beetle</span> Family of beetles

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is the largest family in the beetle order, and one of the largest families of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.
