Staphylinus View in CoL Linne´, 1758 (stat. nov.)

TYPE SPECIES: Staphylinus erythropterus Linne´, 1758 .

COMMENTS: All members of this genus share the synapomorphy of the middle coxal cavities not margined posteromedially ( fig. 64 View Figs ). In addition, they share ( 1) superior line of pronotal hypomeron markedly and relatively abruptly deflexed ventrad, before or at most at middle of pronotum, with its anterior portion situated markedly below basal portion in lateral view ( fig. 112 View Figs ); ( 2) bicolored black body with red elytra and legs red excluding coxae; and ( 3) presence of yellow tomentose pubescence on head and usually also on pronotum, and paired yellow tomentose patches on abdominal tergites.

Further character states include: right mandible with one stout, apically truncate, subemarginate or slightly emarginate tooth, left mandible with two dorsal teeth, and with one somewhat smaller tooth in more ventral plane ( fig. 138 View Figs ); mandibular prostheca narrow, elongate, with ciliae present only at apex ( fig. 15 View Figs ); last segment of maxillary palpus fusiform, narrower and markedly shorter than segment three, asetose ( fig. 24 View Figs ); ligula emarginate; last segment of labial palpus fusiform, narrower and markedly longer than segment two, asetose ( fig. 139 View Figs ); anterior margin of submentum inwardly arcuate, without bead; postmandibular ridge rudimentary to very short; base of infraorbital ridge on the neck distinctly recurved toward nuchal ridge dorsally, sometimes reaching it; superior and inferior lines of pronotal hypomeron connected well before anterior angles of pronotum ( fig. 57 View Figs ); epimeron of prothorax absent ( fig. 50 View Figs ); prosternum with middle portion of basisternite broadly rounded or gradually sloping anteriad; serial long setae on mesosternum originating in moderately impressed punctures in subtransverse to broadly arcuate arrangement; spines on dorsal apicolateral lobe of hind coxae small, almost indistinguishable in size from other setae.

This is a new concept of this genus, restricted to the species around S. erythropterus and S. caesareus . Six Palearctic and one Nearctic species are at present included in the genus.
