Diagnosis. Males of C. bibranchiatus comb. nov. are distinguished from those of the other species of the genus by the vRTA2 transversally bifid with one branch rounded and the other laminar and slightly concave and by the embolus with large, roughly rectangular base, abruptly narrowed and filiform to tip ( Rheims 2010c: 531, figs 1−2). Females resemble those of C. annulatus comb. nov., C. peninsulanus comb. nov. and C. tortugero sp. nov. by the epigyne with median septum with lateral protrusions (Figs 19, 93: lp, Rheims 2010c: 531, figs 3, 7). They are distinguished from these species by the lateral protrusions short, not reaching one-sixth of the median septum width on each side, and by the anterior margins of the lateral lobes curved into the median septum ( Rheims 2010c: 531, fig. 3).
