description: Proprioseiopsis ismailiaensis n. sp.
(Figs 15–19)
Diagnosis. Seta Z5 about 1.4 as long as Z4; z2 and z4 equal in length, slightly longer than the distance between their bases; calyx of spermatheca bell-shaped; the genital shield broad, with posterior margin truncated; ventrianal shield wider than long.
Female (one specimen).
Dorsum (Fig. 15). Dorsal shield mostly smooth, with sparse lateral striae; 469 long and 255 wide, with 16 pairs of setae, six pairs of pores and fourteen pairs of lyrifissures. Setae j1 31, j3 59, j4 4, j5 5, j6 8, J5 10, z2 37, z4 37, z5 6, Z1 8, Z4 129, Z5 178, s4 94, S2 10, S4 11, S5 19, r3 26, R1 17. All setae smooth, except Z5, lightly serrate. Peritreme extending forward to level of j1.
Venter (Fig. 16). Sternal shield mostly smooth, with few lateral striae; with three pairs of setae and two pairs of lyrifissures. Distances between st1–st1 59, st2–st2 79, st3–st3 88, st4–st4 75. Genital shield smooth; distance between st5–st5 92. Ventrianal shield subpentagonal, with transverse striae in the anterior two thirds; 125 long, 131 wide at ZV2 level and 104 wide at level of anus; with three pairs of pre-anal setae and a pair of pre-anal pores posteromesad of JV2. Seta JV5 86. Ventral setae smooth. Two pairs of metapodal plates.
Spermatheca (Fig. 18). Calyx of spermatheca bell-shaped, 19 long; atrium attached directly to calyx.
Gnathosoma. Corniculi parallel to each other; basal width of corniculus 4, distance between bases of corniculi 10. Movable cheliceral digit 31 long, with one tooth; fixed digit 32 long, with three teeth (Fig. 17).
Legs. Macrosetae sharp-tipped: Sge II 36, Sge III 45, Sge IV 84, Sti IV 54, St IV 76 (Fig. 19); chaetotaxy of genu II 2, 2/1, 2/0, 1; genu III 1, 2/1, 2/0, 1.
Type specimens: Holotype female from soil under pomegranate tree, at Ismailia governorate, July 1980 (coll. M.A. Zaher), deposited at the mite collection of the Faculty of Agriculture, Cairo University, Giza, Egypt.
Etymology: The name ismailiaensis refers to Ismailia, the locality where the holotype female was collected.
Remarks. This species is most similar to Proprioseiopsis sharkiensis Basha & Yousef, 2000 and Proprioseiopsis terrestris (Chant, 1959). The former differs from the new species by having Z4 and Z5 much shorter and the calyx of spermatheca trumpet-shaped. The latter differs by having z2 and z4 about half as long as the distance between their bases in addition to the genital shield very broad, with posterior margin rounded and ventrianal shield as wide as long.
This holotype was found among specimens of the mite collection of the Faculty of Agriculture, Cairo University, Giza, Egypt, labelled as Amblyseius lindquisti. The absence of a macroseta on genu I places this species in the belizensis species group of Chant & McMurtry (2005).
