Passandrophloeus
Passandrophloeus is a genus of small beetles in the family Laemophloeidae, established by Kessel in 1921. The genus contains five described species, all described by Grouvelle: P. belli, P. ditomoides, P. falcidens, P. glabriculus, and P. spinosus. The genus is currently listed as taxonomically doubtful in some databases, indicating potential issues with its circumscription or validity relative to related genera. Members of Laemophloeidae are generally associated with dead wood and fungal habitats.
Philothermus
Philothermus is a genus of minute bark beetles in the family Cerylonidae, containing approximately 17 described species. Members are small, compact beetles associated with dead wood habitats. The genus has been documented in Europe, with particular attention to rare species such as P. evanescens in France. Available information on biology and distribution remains limited for most species.
Urgleptes
Urgleptes is a genus of longhorn beetles in the subfamily Lamiinae, established by Dillon in 1956. Species in this genus are small to medium-sized cerambycids with relatively generalized morphological features. The genus has been recorded from dead wood of various hardwood trees, with at least one species (Urgleptes querci) documented from pawpaw (Asimina triloba).
Xylitini
Xylitini is a tribe of darkling beetles within the family Melandryidae, established by C.G. Thomson in 1864. Members of this tribe are primarily associated with dead and decaying wood, where they develop as larvae. The tribe includes several genera of small to medium-sized beetles that are part of the broader saproxylic beetle community.
