Neoseiulella neoviniferae Basha, Mahrous and Mostafa

( Figure 33 )

Neoseiulella grapevini Basha et al. , Chant and Mc- Murtry 2007: 147.

Adult female ( Figure 33a – d )

Dorsal shield ( Figure 33a ) — Dorsal shield distinctly reticulated throughout: length 386 (381 – 390), width 175 (171 – 178) (at level of s4) and 191 (187 – 195) (at level of Z1). Seven pairs of large solenostomes on the dorsal shield: gd1, gd2, gd4, gd5, gd6, gd8, and gd9. Five pairs of poroids. Sublateral setae (r3 and R1) on the lateral margin. Like us, Basha et al. (2004) noted the presence of seven pairs of solenostomes. However, on their drawings gd4 is absent (present on the specimens examined). Dorsal shield bearing 19 pairs of setae, all smooth: j1 23 (21 – 25); j3 24 (22 – 26); j4 14 (12 – 15); j5 12 (10 – 13); j6 16 (15 – 17); J2 15 (14 – 15); J5 15 (14 – 15); z2 10 (9 – 11); z3 24 (22 – 25); z4 19 (17 – 20); z5 14 (13 – 15); Z1 17 (16 – 17); Z4 47 (44 – 49); Z5 62 (59 – 64); s4 23 (22 – 24); s6 26 (25 – 27); S2 35 (34 – 36); S4 33 (31 – 35); S5 28 (26 – 30); sub-lateral setae r3 28 (26 – 30) and R1 25 (23 – 27). Presence of few visible muscles marks (sigilles) on the dorsal shield. Peritreme extending anteriorly to the level of j3 .

Ventral shields ( Figure 33b ) — Sternal shield 62 (60 – 63) long and 67 (66 – 67) wide (at level of ST2), is smooth with two pairs of setae (ST1 and ST2) and two pairs of poroids. ST3 and ST4 on separate platelets. A pair of small poroids accompanying ST4. Genital shield 128 (125 – 131) long and 66 (64 – 67) wide (at level of ST5), smooth. Four elongate platelets or genital sigilla between genital and ventrianal shields. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield subtriangularshaped, 130 (125 – 134) long and 98 (95 – 101) wide (at level of ZV2), distinctly reticulated, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and a pair of solenostomes gv3 posterior to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 48 (46 – 50) long, smooth. Primary metapodal plate or inguinal sigillum 39 (38 – 40) long and 5 (4 – 6) wide.

Spermatheca ( Figure 33c ) — Cervix 4 (3 – 4) long, cup-shaped.

Chelicera ( Figure 33d ) — Two large teeth and a pilus dentilis on the fixed digit. Movable digit 38 (36 – 39) long, unidentate. Basha et al. (2004) mentioned that the fixed digit bears three teeth.

Legs ( Figure 33e ) — Measurements of legs: leg I 341 (333 – 349); leg II 286 (285 – 286); leg III 285 (284 – 286); leg IV 381 (369 – 393). Seven setae (2- 2/0, 2/0-1) on the genu II. One macroseta 42 (37 – 47) long, on the basitarsus IV.

Material examined — Four female paratypes deposited in the collection of Plant Protection Department , Faculty of Agriculture, Zagazig University, Egypt .

Adult male

The male of this species is unknown.

Previous reports — N. neoviniferae is only known from Al-Sharkia Governorate, El-Khattara District ( Egypt) on Vitis vinifera L. ( Vitaceae ).

Remarks — N. neoviniferae is similar to N. montforti but differs by the presence/ absence of gd5 (present on N. neoviniferae ; absent on N. montforti ), the shape of the spermatheca (c-shaped on N. neoviniferae ; U-shaped on N. montforti ) and measurements of some dorsal setae (j6, J2, z2, Z1 and R1).
