Two New Cyphoderus Nicolet (Collembola: Paronellidae) of the “bidenticulati-group” with Dental Plurichaetosis from Brazil

Cryptic subterranean diversity in Collembola indicates that Hot Spot in ferruginous rock may have serious implications in Brazilian conservation policy.

“…Homology. The terminology used in the diagnoses for the hypotheses of homology followed: labial chaetotaxy after Gisin [29] with additions of Zhang & Pan [30]; Fjellberg [31] for labial palp papillae and maxillary palp; postlabial chaetotaxy after Chen & Christiansen [32], with adaptations of Cipola et al [33] for J series; clypeal chaetotaxy after Yoshii & Suhardjono [34]; labral chaetotaxy after Cipola et al [35]; unguiculus lamellae after Hüther [36]; Anterior dens chaetotaxy after Oliveira et al [37]; Mari-Mutt [38] for dorsal head chaetotaxy, with additions of Soto-Adames [39]; Szeptycki [40] and Zhang & Deharveng [41] for S-chaetotaxy; and Szeptycki [42] for dorsal chaetotaxy, with additions and modifications provided by Soto-Adames [39] and Zhang et al [43]. Symbols used to depict the chaetotaxy are presented in Fig.…”

A Highly Troglomorphic New Genus of Sminthuridae (Collembola, Symphypleona) from the Brazilian Semiarid Region

“…The cave fauna of Brazilian springtails is mainly represented by species of Acherontides Bonet, 1945 [ 6 ] (Poduromorpha); Cyphoderus Nicolet, 1842 [ 7 ], Troglobius Palacios-Vargas and Wilson, 1990 [ 8 ], Trogolaphysa Mills, 1938 [ 9 ], Pseudosinella Schäffer, 1897 [ 10 ], Coecobrya Yosii, 1956 [ 11 ] (Entomobryomorpha); Arrhopalites Börner, 1906 [ 12 ], Pararrhopalites Bonet and Tellez, 1947 [ 13 ] and Keratosminthurus (Symphypleona), summing up more than 40 species [ 2 , 4 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Although many recent efforts aimed to describe the Brazilian cave fauna of Collembola, as in [ 4 , 15 , 16 , 18 , 19 , 21 ], it is noteworthy that most subterranean ecosystems in the country are undersampled for invertebrates in general (including the springtails fauna), especially in the semiarid landscapes. On the other hand, preliminary data supports that the Caatinga, a unique semiarid domain only found in Brazil, can host complex cave systems which shelter a high number of troglomorphic endemic invertebrates, many of them potentially troglobitic [ 22 , 23 ].…”
