Abstract: | Two new species of the denticulata-group in the genus Ceratophysella Börner, 1932, C. rogerarlei sp.n. and C. nataliae sp.n., both from Brazil are described and illustrated. Ceratophysella rogerarlei sp.n. is similar to C. engadinensis (Gisin, 1949) in overall chaetotaxy, but it is unique by the combination of Ant. IV with trilobed apical bulb and 5 dorsal sensilla, PAO atypical with antero-lateral lobe clearly shorter than the antero-medial lobe, and the reduction of trunk dorsal chaetotaxy and number of macrosetae. Ceratophysella nataliae sp.n. is similar to C. gibbosa (Bagnall, 1940) and C. tupamara Palacios-Vargas & Bocanegra, 2012 but differs in dorsal abdominal chaetotaxy, Ant. IV with trilobed apical bulb (simple in C. gibbosa) and dorsal manubrium with 18+18 setae (8+8 in C. tupamara). A key to South American species of the genus is provided. With the descriptions presented, there are now nine species of Ceratophysella recorded from South America and six from Brazil. © Koninklijke Brill NV, Leiden, 2017. |
