Genus Plusiocampa Silvestri, 1912

Diagnosis.

Apparently smooth cuticle, usually reticulated at high magnification, rosette-like pores absent. Head with a frontal process with or without tuberculate setae. In non-troglomorphic species, cupuliform organ with four or five spheroidal olfactory chemoreceptors in polygonal net, with pore surface made by at least one cup-shaped fold and a central structure ending in a terminal pore. In troglobiomorphic species, spheroidal olfactory chemoreceptor with more folds in spiral, radial, or other complex shapes and a more visible polygonal net with pore surface. Sensillum of third antennomere in ventral position. Meso- and metathorax with a few macrosetae but frequently with medial anterior, lateral anterior, lateral posterior, and medial posterior (exceptionally medial intermediate and lateral intermediate) macrosetae. Femur with one to five dorsal macrosetae; tibia with one to three ventral macrosetae. Elbow-like claws usually with large lateral crests and setiform smooth lateral processes, rarely with a few barbs on proximal part. Abdomen with lateral anterior and posterior macrosetae and never with medial anterior macrosetae. Sternal macrosetae: sternite I with 6 + 6 up to 60 (in total) macrosetae; sternites II – VII with 4 + 4 to up to 14 + 14 macrosetae; sternite VIII with 2 + 2 up to 4 + 4 macrosetae. Secondary sexual differences in shape of the first urosternite appendages and the number of glandular setae.

Remarks.

A genus with five subgenera and a total of 71 species described ( Condé 1956; Sendra et al. 2021 a).

Distribution.

This genus is primarily distributed in the Western Palearctic, with the exception of Plusiocampa sinensis , which will require further review in the future.
