Diagnosis

Together with C. lehibemavo   sp. nov. and C. saha   sp. nov., Chimarra cebegepi   sp. nov. forms a subgroup of three closely related species. C. lehibemavo   sp. nov. is characterized by the short internal sclerite of the phallic apparatus ( Fig. 2 View Fig D–E), this latter is long and apically curved in the other two species. C. cebegepi   sp. nov. differs from C. saha   sp. nov. by the distal margin of the inferior appendage slightly concave and regularly rounded in lateral view ( Fig. 3 A View Fig ). Moreover C. saha   sp. nov. is characterized by the lateral deflection of the dorsal lamina of the phallotheca ( Fig. 13 E View Fig ), which is more developed than in C. cebegepi   sp. nov. ( Fig. 3 E View Fig ).

Etymology

The name is designed from the acronym of the Centre de Biologie pour la Gestion des Populations.

Description

SIZE. Forewing 8.5 mm, hind wing 6.8 mm.

TERGUM X. Lateral lobes not as deeply divided as in C. lehibemavo   sp. nov., dorsal branch longer than ventral one (lateral view).

INFERIOR APPENDAGES. Dorsal branch elongate, regularly narrowing; ventral branch short; internal lobe constituted by six small indentations ( Fig. 3C View Fig ); distal margin concave and regularly rounded in lateral view ( Fig. 3A View Fig ).

PHALLIC APPARATUS. Phallotheca split from mid-length in two asymmetrical laminas of equivalent length; internal sclerite long (longer than the laminas of the phallotheca) with curved apex and, before midlength, short and triangular protuberance ( Fig. 3D View Fig ); phallotremal sclerite present with two lateral, hookshaped elements.
