Micaria Westring, 1851

Remarks.

Type species. Micaria fulgens (Walckenaer, 1802), originally described as Aranea fulgens .

Diagnosis.

Gnaphosids of the " Micaria -group" ( Murphy 2007), differing from Arboricaria by the more or less ovoid, posteriorly not truncate sternum in both sexes, the ovoid, not bulging bulbus with a mostly present median apophysis, the palpal tibial apophysis, sometimes poorly expressed, not bifid in males, the epigynal groove in females, if present, without distinctly chitinized posterior margins.

Composition.

101 species ( WSC 2015).

Distribution.

Holarctic. Other records require confirmation.

An analysis of the new Micaria species described from the Palaearctic since Bosmans and Blick (2000), all listed in WSC (2015), shows no match with Arboricaria characters. Therefore, despite the previous neglect of Arboricaria , no new species of this genus have been described within Micaria sensu lato since 2000. In addition, all extra-Holarctic records of Micaria are doubtful; these species most likely belonging to other genera or even families ( Murphy 2007).
