description: Copuetta comorica sp. nov.
Figs 41, 42, 99, 110 –113
Etymology: The species name is taken from the Comoros Islands, to which it is endemic.
Diagnosis: Males of this species are closely related to C. maputa sp. nov., but the embolus base is very short and the embolus tip is directed distally (Fig. 99); in C. maputa sp. nov. the embolus base is quite long and upright, with a short and prolaterally directed embolus tip (Fig. 106). Females have an epigyne with opposing lateral semicircular ridges that meet along the midline (Fig. 112), while clearly separated in C. maputa sp. nov. (Fig. 143).
Male (holotype, Nioumbadjou, MRAC 158454). Measurements: CL 2.73, CW 2.15, AL 3.00, AW 1.65, TL 5.60 (5.60–5.85), FL 0.30, SL 1.25, SW 1.22, AME–AME 0.05, AME–ALE 0.01, ALE–ALE 0.46, PME–PME 0.13, PME–PLE 0.06, PLE–PLE 0.52, PERW 0.78, MOQAW 0.48, MOQPW 0.46, MOQL 0.52.
