Caneorhinus lineatus (Blanchard)

( Fig. 9 A–B)

Cylydrorhinus lineatus Blanchard 1851: 355 ; Berg 1884: XCIX ( Adioristus ); Bruch 1915: 412 ( Cylindrorrhinus ); Kuschel 1952a: 121 ( Caneorhinus ).

= Cylindrorrhinus confusaneus Berg 1899: 61 ; Enderlein 1912: 79 ( Cylydrorhinus confuseanus , lapsus); Kuschel 1952a: 121 ( Cylindrorhinus ).

= Caneorhinus gravidus ( Burmeister 1879) n. syn. Burmeister, 1879: 208 (Cylyndrorrhinus); Kuschel 1952a: 121 ( Caneorhinus ).

C. gravidus (Burmeister) is here established as a new junior synomym of C. lineatus (Blanchard) . Comparison of two C. gravidus sintypes (male and female) deposited at MACN with C. confusaneus holotype deposited at MLP did not provide morphological differences among specimens. Also, male genitalia of specimens determined as C. lineatus and C. gravidus were compared and did not allow the identification of separate species.

Geographic distribution as in figure 10.
