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. 2View 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 AView Fig). Moreover C. saha  sp. nov. is characterized by the lateral deflection of the dorsal lamina of the phallotheca ( Fig. 13 EView Fig), which is more developed than in C. cebegepi  sp. nov. ( Fig. 3 EView 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. 3CView Fig); distal margin concave and regularly rounded in lateral view ( Fig. 3AView 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. 3DView Fig); phallotremal sclerite present with two lateral, hookshaped elements.
