The Staphylinini are a cosmopolitan group of relatively large staphylinid beetles, including the rove beetles that are the most familiar members of the family. Representatives of the Staphylinini have antennae inserted closer to the eyes than to each other, a well developed apical maxillary palpomere, a relatively wide neck (if any), and no separate sclerotised plate anterior to the prosternum (Newton et al. 2001). A major clade within the group has been referred to as the 'Staphylinini propria', members of which are often distinguished by a dorsal basal ridge on the head capsule, a complete fusion of the pronotum and prosternum inside the procoxal cavity, and a transverse ridge on the hind coxa (Brunke et al. 2016).

Paederus

Paederus riparius, from here.

Belongs within: Paederini.

Paederus is a diverse genus of staphylinid beetles, generally coloured in contrasting patterns of red and black. Many species are found in damp habitats alongside rivers or in marshy fields. A number of species produce pederin and other haemolymph compounds that can cause severe dermatitis upon contacting human skin (Newton et al. 2001).

Characters (from Fagel 1961): Pronotum and prosternum not separate; weak prosternal extension; abdomen thick; pleurites well marked; sternite 1 with strong longitudinal carina; median lobe of aedeagus with ventral and dorsal lamella, median opening, parameres generally symmetrical, fused to median lobe over large part of their length and carrying numerous rows of bristles which do not reach the apex.
