Subfamily Plusiocampinae Paclt, 1957

Plusiocampinae Paclt, 1957: 42 .

Diagnosis ( Condé 1955a; Paclt 1957; Sendra et al. 2017a)

Since the only diagnostic character of Plusiocampinae (as suggested by Paclt 1957) is the higher number of macrosetae on the pronotum, this taxon seems to be paraphyletic. The pronotum never has less than 4+4 macrosetae. However, many of the genera can be considered monophyletic within Plusiocampinae . This is the case for Anisuracampa , Cestocampa , Condeicampa , Hystrichocampa , Patrizicampa , Plusiocampa , Plutocampa , Simlacampa and Vandelicampa , characterized by pretarsal lateral crests. Nonetheless, these lateral crests are absent in Silvestricampa and Turkmenocampa , clearly isolating them from the other genera.

5. Pretarsal lateral processes absent ........................................................ Plutocampa Chevrizov, 1978

7. Simple claws; pretarsal lateral processes absent, medial-intermediate and lateral-intermediate macrosetae on mesonotum and metanotum ........................................... Silvestricampa Condé, 1950

– Pretarsal claws with sharp side-shoot; pretarsal lateral processes laminar, without medial posterior macrosetae on mesonotum and metanotum ........................ Turkmenocampa Sendra & Stoev, 2017

This key includes 11 accepted genera plus three species, Plusiocampa (Dydimocampa) sinensis , Plusiocampa (Dydimocampa) lipsae and Plusiocampa kashiensis from China, which remain in an uncertain position ( Sendra et al. 2012a). Three new troglomorphic genera from China, Indochina and the Aegean islands, which are currently under description (Sendra, in prep.), are excluded.
