Figs 6–7 , 39

Diagnosis

The male of Andromma albinovani sp. nov. is characterized by the shape of the VTA and RTA being simpler than in all other species of Andromma except A. aethiopicum , and the female by the epigyne with tubular structures visible in transparency and comma-shaped copulatory openings.

Etymology

The species name is a patronym as a tribute to Benoit Albinovanus, the driving force behind the choral ‘Museicanti’ of the Royal Museum of Central Africa in Tervuren.

LEG I MEASUREMENTS. Fe: 0.89, P: 0.33, T: 0.62: Mt: 0.66; t: 0.53; total: 3.03.

LEG FORMULA. 4123.

MALE PALP ( Fig. 6D–G ). RTA flattened, twisted with innermost prong sharp, outer tip rounded; VTA a transverse curved disk with pointed retrolateral extremity; bulbus fairly large, alveolus about ⅔ of cymbium, which is somewhat curved inward; two curves of sperm duct visible in tegulum retrolaterally; embolus originates on posterior part of tegulum, runs along its prolateral side, ending in curved tip accompanied by small membranous conductor.

Female (paratype, Fig. 7 )

MEASUREMENTS. Total length 2.70. Carapace length 1.14, width 0.92, height 0.43.

COLOUR ( Fig. 6C ). very similar to male.

LEGS. Missing from femur onwards.

EPIGYNE ( Fig. 7A–D ).Copulatory openings inconspicuous, comma-shaped, leading to initially broadening copulatory ducts running in posterior direction, then inward, followed by an anterior running stretch and finally a second stretch in posterior direction, ending in small spermathecae with a short, postero-lateral fertilisation duct and clearly defined, outward directed sickle-shaped sclerites.

Distribution

Known only from the type locality in central Ivory Coast ( Fig. 39 ).
