Neoseiulella elongata Ferragut and Peaea-Estevez 2003: 164 ; Moraes et al. 2004: 293; Moraza and Peaea- Estevez 2006: 58; Chant and McMurtry 2007: 147.

Adult female ( Figure 27a – e )

Dorsal shield ( Figure 27a ) — Dorsal shield heavily reticulated: length 394; width 175 (at level of s4), 178 (at level of Z1), with four pairs of solenostomes: gd2, gd6, gd8, and gd9. Four pairs of poroids. Sublateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth: j1 20; j3 16; j4 12; j5 11; j6 14; J2 16; J5 11; z2 14; z3 16; z4 16; z5 11; Z1 20; Z4 23; Z5 29; s4 17; s6 19; S2 20; S4 21; S5 19; sub-lateral setae r3 23 and R1 24. Presence of few visible muscles marks (sigilles) on the dorsal shield. Peritreme extending anteriorly to the level of z2. It is noteworthy that the peritreme differs from the ones of the other species of the genus Neoseiulella as its anterior surface is striate.

Ventral shields ( Figure 27b ) — Sternal shield 83 long and 73 wide (at level of ST2), smooth, with two pairs of setae (ST1 and ST2) and two pairs of small poroids. Two other pairs of sternal setae (ST3, ST4) on separate platelets. A pair of small poroids accompanies ST4. Genital shield 140 long and 66 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating genital and ventrianal shields folded under genital shield. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield subtriangular-shaped, 134 long and 93 wide (at level of ZV2), lightly reticulated, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2), and without solenostome gv3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 20 long, smooth. Primary metapodal plate or inguinal sigillum 42 long and 4 wide.

Spermatheca ( Figure 27c ) — Cervix 5 long, shallowly cup-shaped.

Chelicera ( Figure 27d ) — One tooth and a pilus dentilis on the fixed digit. Movable digit 44 long, unidentate.

Legs ( Figure 27e ) — Measurements of legs: leg I 335; leg II 281; leg III 275; leg IV 356. Seven setae (2- 2/0, 2/0-1) on the genu II. One macroseta, 61 long, on the basitarsus IV.

Material examined — A female paratype deposited in the Department of Agroforestal Ecosystems , Universidad PolitØcnica of Valencia, Spain .

Adult male

The adult of this species is unknown.

Previous reports — N. elongata is only known from the Canary Islands on Pinus canariensis C. Sm. (Pinaceae) .
