Phytoscutus lienoulouisi Moraes, Zannou & Oliveira , n. sp.

( Fig. 4 )

Diagnosis. This species is characterized by having seta z2 more than twice as long as z4; seta j4 at about the same level as z2; sternal shield totally reticulate; Zv1, Jv4 and Jv5 on integument.

Female. (2 specimens measured)

Dorsum. Dorsal shield mostly smooth, with few undulating transverse striae between setae Z4, 435 long and 315 wide. Setae j1 36(34–38), j3 65(62–67), j4 8, j6 13, J5 11, z2 79(77–82), z4 30(29–32), z5 8, Z1 29, Z4 186(182–189), Z5 236(235–237), s4 194(173–216), S5 8, r3 8, R1 8.

Venter. Sternal shield reticulate; posterior margin concave; distances between St1-St3 54, St2-St2 72. Genital shield reticulate, distance between St5-St5 91. Ventrianal shield reticulate, anterior margin straight, lateral and posterior margins rounded, 176 long, 177(173–181) wide at widest level and 158 wide at level of anus, with 3 pairs of preanal setae (Jv1, Jv2, Zv2); Jv4 and Zv1 on soft cuticle; Jv5 long (104); preanal pores mesad and slightly posterior to Jv2. With 1 pair of metapodal shields.

Chelicera. Movable digit 27 long, with 2 teeth; fixed digit 18 long, with 7 teeth and a pilus dentilis.

Spermatheca. Calyx funnel-shaped, 14 long.

Legs. Sharp-tipped macrosetae; Sge I 53, Sge III 62, Sti III 61, Sge IV 104(98–110), Sti IV 94(91–96), St IV 77.

Locality and type material. Holotype female from Mangifera indica , 5 km N Muyuka, Cameroon, 09-II- 1991, L. Louis, deposited at ESALQ-USP. One paratype female from unknown plant, 12 km N Obala, Cameroon, 05-II-1991, L. Louis, deposited at ESALQ-USP.

Etymology. This new species is named after Liénou Louis, a Cameroonian acarologist involved in the collections of most of the phytoseiids from Cameroon treated in this paper.

Remarks. This species falls into the gongylus species group. Indeed, its characters fit those of this species group.

Phytoscutus glomus ( Pritchard & Baker, 1962) differs from this new species by having z2 and z4 much shorter and the central area of the sternal shield smooth. Phytoscutus eugenus differs from this new species by having sternal shield smooth, striate genital shield and by lacking Jv4 (or Jv4 is on the ventrianal shield; see redescription of P. eugenus previously presented in this paper). Phytoscutus reunionensis ( Ueckermann & Loots, 1985) differs from this new species, by having z2, Z4, Z5 and s4 at least 35% shorter than in the new species and sternal shield smooth.
