The genus is not revised so the following characters (in combination) should be considered only as a partial list: left mandible with single tooth; antennomere 1 less than twice as long as antennomere 2; eyes large; pronotum with dense micropunctures (not in all species).	en	Chatzimanolis, Stylianos (2021): Out of Xanthopygus (Coleoptera: Staphylinidae): escape from polyphyly.

57F63C0A54AD5592A856D8C2AC1A5D57.taxon	diagnosis	Diagnosis. This genus can be distinguished from all other genera in Xanthopygina based on the combination of the following characteristics: head shape rectangular; posterior margin of head slightly extended posteriad on each side of the neck (apomorphy; except in Ph. corcovadoensis and Ph. mirabilis); antennomeres 1 - 5 elongate; labial palpomere 3 not securiform; medium size eyes; superior marginal line of pronotal hypomeron not continuing to anterior margin; postcoxal process present; pronotum with sparse micropunctures but no transverse lines visible at 70 x magnification (apomorphy); mesoscutellum without dense micropunctures (apomorphy); mesoventral process narrow and rounded (apomorphy); metatarsi with setose dorsal surface (apomorphy); tergite 3 (at minimum, some species 3 - 4 or 3 - 5) with arch-like carina; and sternite 7 in males with emargination at posterior margin. For a list of characters that distinguish Photinopygus from Xanthopygus, see Table 2.	en	Chatzimanolis, Stylianos (2021): Out of Xanthopygus (Coleoptera: Staphylinidae): escape from polyphyly.

The name is masculine.	en	Chatzimanolis, Stylianos (2021): Out of Xanthopygus (Coleoptera: Staphylinidae): escape from polyphyly.

2D0E21CA99C25FF09D7FF1DBEAD0D93F.taxon	diagnosis	Diagnosis. This genus can be distinguished from all other genera in Xanthopygina based on the combination of the following characteristics: head shape rectangular; head wider than pronotum (apomorphy; however, head size can be variable among specimens of the same species but wider than pronotum); antennomeres 7 - 10 transverse; left mandible with two teeth separated by deep emargination (apomorphy); labial palpomere 3 not securiform; small size eyes (apomorphy); superior marginal line of pronotal hypomeron not continuing to anterior margin; superior and inferior marginal line of hypomeron produce anterolateral angles not parallel to one other (apomorphy); postcoxal process present; elytra coloration black (except with blue metallic overtones in Xa. xanthopygus); dorsal 1 / 3 of metepisterstum without punctures (apomorphy; state also present in Ph. mirabilis); with more than four spines on the posterior surface of metacoxae (apomorphy; less than four in Xa. xanthopygus); tergites 3 - 5 with arch-like carina; and sternite 7 in males with emargination at posterior margin. For a list of characters that distinguish Xanthopygus from Photinopygus, see Table 2.	en	Chatzimanolis, Stylianos (2021): Out of Xanthopygus (Coleoptera: Staphylinidae): escape from polyphyly.
