Zoobank: 24BED0D5-7245-4975-A055-0C435A03BD78

Type species — Duoparus hyeresensis n. gen. n. sp.

Description — Adult female. Aspidosoma procurved, with four pairs of setae bo, ro, la and ex ; opisthosoma with 11 pairs of setae, c1, c2, d1, e1, f1, f2, h1, h2, ps1, ps2 and ps3. Poroidotaxy: ia, im, ip, ih. Eye spots absent. Two pairs of subequal aggenital setae, supposedly ag1 and ag3 with ag2 and ag4 absent. Empodium and claws absent on leg I, each of other legs with ciliate empodium and two claws, without empodial hooks. Femur IV divided. Leg chaetotaxy: leg I 9 + ω – 3 + φ + κ – 3 – 3 – 1; leg II 7 + ω – 2 – 3 – 3 – 1; leg III 6 – 2 – 2 – 2 – 1; leg IV 6 – 2 – 1 – 1 + 1 – 0. Epimeral formula 3-1-4-2.

Diagnosis — Adult female of the genus is characterised by the presence of two pairs of ag setae, one seta on trochanters I to III, seven setae on tarsus II and six on each of tarsi III and

IV. The genus is closely related to Pseudopronematulus that differs in having four pairs of ag setae.

Etymology — The genus name refers to the presence of only two pairs of aggenital setae (ag): ‘ duo ’, Latin for two and ‘ par ’, Latin for pair.

Remark — André (1979: 204) considered the description of a new genus based on one specimen to be unadvisable, except when the specimen exhibits very special characteristics. We consider the presence of only two ag setae a special characteristic and therefore describe this new genus. More diagnostic features can be found in the differential diagnosis of the type species, some of which might be generic, but we limit the genus description mostly to chaetotaxy of body and legs ( André 1980).
