3. - Campodea (?) pagei Silvestri, 1931

Description.

Body 3.5 mm length; epicuticle no describe; antennae 0.4 × shorter than the body length with 19 or 20 antennomeres as long as wide; sensillum of the third antennomere unknown; - pronotum with 2 + 2 (ma, lp 3) short thick macrosetae with tiny distal barbs; short and thick clothing setae with tiny apical barb; marginal setae slightly longer than clothing setae with tiny distal barbs; metathoracic leg 0.3 × as long as body; non macrosetae on urotergites I-VIII plus abdominal IX-X segments except a few strong setae probably macrosetae on posterior margin of abdominal segment X; urosternite I with 5 + 5 short macrosetae bearing few distal barbs; urosternites II-VII with 3 + 3 short macrosetae with few distal barbs; appendages of first urosternite subcylindrical slightly enlarged in males; cerci 0.45 × as long as body with apparently ≤ 25 primary article plus basal one, covered with barbed setae much longer on distal articles.

Habitat.

Deep layers in soil, probably an endogean species.

Note.

At present we considered this species as belonging to the genus Campodea , but unknown subgenus. Campodea pagei lacks macrosetae on the abdominal segments, except for the tenth abdominal segment that supports a row of posterior macrosetae. This feature is completely unknown in other Campodea species. Nevertheless, the study of newly collected material is necessary to make further taxonomic decisions.
