Hysteronotal shield 48–53 long and 80–90 wide at level of anterior margin, 30–34 wide at level of posterior margin. This shield bearing setae d1 and devoid of ornamentation. Setae e1 situated at level of posterior margin of hysteronotal shield, flanking this shield, or situated directly on its posterior margin. Opening of bursa copulatrix situated near to level of setal bases e2. Idiosomal venter. Epigynum about 70 wide. Projection on posterior margin of coxal fields II almost indistinct.

Legs. Legs III and IV about 140 long. Tarsi III and IV about 40 long, subequal to pretarsi in length. Lengths of leg solenidia: ω 3 I and ω 1 II about 25, ω 1 I about 12, φ I and φ II about 45, σ 1 I and σ II about 17.

Type material. Male holotype, 5 male, 6 female, 2 male and 2 female tritonymph, 4 protonymph, and 3 larva paratypes ( IRSNB) from Miopithecus talapoin (Schreber) ( Primates : Cercopithecidae ) died in “Avicentra” ( Belgium), host originated from the Democratic Republic of the Congo,, 19 October 1965, coll. A. Fain.

Type deposition. The whole type series is deposited in IRSNB.

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.

Differential diagnosis. The new species is very close to Paracoroptes gordoni Lavoipierre, 1955 and differs from it by the following. In both sexes of P. miopithecus sp. n., the idiosoma dorsally is covered by numerous scales or verrucosities and the subcapitulum is without ventral projections; in males, the posterior projections of coxal fields II are weakly developed, widely rounded; in females, the posterior projections of coxal fields II are almost indistinct, setae e1 are flanking the posterior margin of the hysteronotal shield or situated at its margin. In both sexes of P. gordoni , the idiosoma dorsally lacks scales or verrucosities and the subcapitulum bears a pair of widely rounded ventral projections; in males, the posterior projections of coxal fields II are hook-like; in females, the posterior projections of coxal fields II are distinct, setae e1 are posterior to the hysteronotal shield.

Hosts and distribution. This species is known only from the type host Miopithecus talapoin from the Democratic Republic of the Congo.
