Subgenus Dicampa Silvestri, 1932

Dicampa Silvestri, 1932a: 116 .

Diagnosis ( Silvestri 1932a; Condé 1956a)

Notal formula with 1+1 ma, 1+1 la, 1+1 lp macrosetae on pronotum; 1+1 ma, 1+1 la on mesonotum and 1+1 ma on metanotum; epicuticle with microdenticles in all species reviewed with exception in one troglobitic species ( C. (D.) melici Sendra, 2015 ); dorsal and lateral tarsal setae smooth; 0+0 or 1+1 lp and 0+0 or 1+1 la macrosetae on V–VII urotergites; 3+3 (2+2) lp macrosetae on VIII urotergite; 5+5 (4+4) lp macrosetae on IX abdominal segment; 0+0 or 1+1 ma macrosetae on urotergites I–IX; first urosternite with 6+6 macrosetae, 4+4 on II–VII urosternites, 1+1 on VIII urosternite; first urosternite of male with glandular g 1 -setae, subtrapezoidal appendages with glandular a 1 and a 2 -setae; female with subcylindrical appendages with glandular a 1 -setae.

Habitat and distribution

The genus Dicampa includes 33 mostly soil-dwelling species ( Condé 1956a), except three caveadapted species: (C. (D.) taurica , C. (D.) neuherzi and C. (D.) melici ). It is well distributed around the Mediterranean Basin, three of its islands and the Black Sea territories included ( Silvestri 1949; Rusek 1965a; Sendra et al. 2006) ( Fig. 59 ). Its presence outside this distribution area should be reviewed. Species of Dicampa have a preference for territories under influence of the Mediterranean climate, mostly dwelling in the B horizon. In general, species of Dicampa show clear adaptations to the endogean habitat: small body size, short appendages, reduction in the number of antennomeres, cercal articles and presence hick and abundant microdenticles and short clothing setae in the epicuticle ( Sendra et al. 2017a).
