Staphylinus maxillosus

COMMENTS: Members of this genus may be easily recognised by the following shared character states: (
1
) palpifer with one long subapical seta and three to four shorter apical setae; (
2
) disc of pronotum and most of dorsal face of pronotum virtually impunctate and asetose; (
3
) middle coxae widely separated by broadly rounded apical margin of mesosternum; (
4
) pronotal hypomeron with superior line becoming obsolete near anterior angles of pronotum and not joining the inferior line (
fig. 49
); (
5
) presence, on both dorsal and ventral faces of body, of long, moreorless variegate pubescence varying in color from black to grayishsilver, grayishgolden, yellowishred, or brownishred (such pubescence not present in a few species occurring elsewhere); (
6
) anterior projection of metasternum very broad, with margins obsolete; and (
7
) dorsal apicolateral lobe of hind coxa without distinct spines, or spines very fine.
Further character states include: mandibles each with microsculpture on mediobasal portion; mandibular prostheca copiously ciliate along entire length, with long, dense basal ciliae gradually shortening apicad; postmandibular ridge absent; deflected portion of pronotal disc visible in ventral view from about anterior edge of pronotal epimeron, which is well developed and membranous; metasternum oblique, highly convex between coxae, then horizontal.
This genus is assigned by some authors (e.g., Coiffait, 1974: 557; Moore and Legner, 1979: 32) to the subtribe
Xanthopygina
based on the configuration of the superior and inferior lines of the pronotal hypomeron (see above). Although
Creophilus
(with
Hadrotes
and
Thinopinus
) seems to be intermediate between the two subtribes, characters 1, 6, and 7 above are shared exclusively with members of the
Staphylinina
; together with the absence of the postmandibular ridge, these confirm their closer affinity with the
Staphylinina
.
