Diagnosis

Chimarra jejyorum  sp. nov. is closely related to C. gattolliati  sp. nov. The two species can be distinguished by the shape of the inferior appendages, as discussed in the diagnosis of C. gattolliati  sp. nov. or, due to the size of the phallic apparatus, by the phallotheca, split shortly after the base in C. jejyorum  sp. nov. ( Fig. 9DView Fig), after mid-length in C. gattolliati  sp. nov. ( Fig. 7DView Fig).

Etymology

From the Malagasy ‘jejy’ (a traditional musical instrument). It is a reference to the name of the Mountain Marojejy, in translation: where there are many guitars.
