Diagnosis. This species is characterized by the absence of S5 and by having seta Z1 minute; calyx of spermatheca trumpet-shaped; macroseta on telotarsus of leg IV at least 20% longer than those on genu, tibia and basitarsus of the same leg.

Dorsal shield 281(272–296) long and 156(155–157) wide; lightly sculptured, with few rounded elements posterior to j6 and to Z1, a pair of incisions at level of s4 and a pair of medium sized pores postero-mesad of z5.

Peritreme ( Fig. 2 F). Extending to level between j3 and z2.

Venter ( Fig. 2 G). Ventrianal shield almost rhombus-shaped, with anterior margin round, and smooth, 97 long, 116 wide at lateral corners; with 3 pairs of preanal setae, 5 pairs of lyrifissures (1 anterior and vertically in line with Jv1, 1 laterad and about in line and 1 laterad and slightly posterior to JV1, 1 laterad and slightly posterior to ZV2, 1 laterad and slightly posterior to JV2), preanal pores not distinguishable.

Spermatodactyl ( Fig. 2 H). L-shaped, shaft 18(17–18) long; foot 13(13–14) long.

Legs. Macrosetae of same shapes as in female; Sge II 13 (12–14), Sge IV 24 (22–25), Sti IV 26 (26–27), Sbt IV 38 (37–40) and Stt IV 49 (45–52). Chaetotaxy of genua II and III as in female.

Locality and type material. Holotype female and 1 paratype female from Chromolaena odorata (Asteraceae) , 28 km S Dunkwa, Western Region, Ghana, 11-XI-1989, J.S. Yaninek, deposited at ESALQ-USP; 2 paratype females from Chromolaena odorata , 28 km S Dunkwa, Western Region, Ghana, 11-XI-1989, J.S. Yaninek, deposited at IITAIM; 3 paratype females and 1 allotype male from Pueraria sp. ( Fabaceae ), 51 km S Dunkwa, Western Region, Ghana, 11-XI-1989, J.S. Yaninek, deposited at ESALQ-USP; 1 paratype female and 1 paratype male from unknown plant, 15 km S Obuasi, Ashanti Region, Ghana, 10-XI-1989, J.S. Yaninek, deposited at IITAIM; 1 paratype female from unknown plant, 25 km S Tarkwa, Western region, Ghana, 11-XI- 1989, J.S. Yaninek, deposited at IITAIM; 1 paratype female, from Solanum melongena (Solanaceae) , 29 km N Tarkwa, Western region, Ghana, 10-III-1990, J.S. Yaninek, deposited at ESALQ-USP.

Etymology. The epithet ghanaensis refers to the country where the types of this species were collected.

Remarks. The absence of S5 characterizes this species as belonging to orientalis species group of Chant & McMurtry (2003b). Paraphytoseius nicobarensis (Gupta) differs from this species by having Z1 as long as j1 and as r3, and ventrianal shield ca. 45% wider at level of ZV2 than at level of anus. The remaining species of the orientalis group [ P. bhadrakaliensis (Gupta) , P. chihpenensis Ho & Lo , P. hilli Beard & Walter , P. horrifer (Pritchard & Baker) , P. orientalis (Narayanan, Kaur & Ghai) , P. santurcensis De Leon , P. seychellensis Schicha & Corpuz-Raros , P. urumanus (Ehara) , P. parabilis (Chaudhri) and P. subtropicus (Tseng) ] differ from the new species by having calyx of spermatheca dish-shaped.
