( Figure 28 )

Neoseiulella ferraguti Moraza and Peaea-Estevez 2006: 56-58 .

Adult female ( Figure 28a – e )

Dorsal shield ( Figure 28a ) — Dorsal shield smooth: length 365; width 226 (at level of s4), 264 (at level of Z1), with seven pairs of solenostomes: gd1, gd2, gd4, gd5, gd6, gd8, and gd9. Seven pairs of poroids. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth except Z4 and Z5 which are slightly serrated: j1 28; j3 49; j4 31; j5 32; j6 38; J2 34; J5 19; z2 15; z3 54; z4 47; z5 29; Z1 34; Z4 77; Z5 94; s4 62; s6 64; S2 71; S4 54; S5 33; sub-lateral setae r3 28 and R1 35. Most dorsal setae of opisthosomal area (S2, S4, S5, Z4, Z5, and J5) on tubercles. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 28 b ) — Sternal shield 67 long and 68 wide (at level of ST2), smooth, with two pairs of setae (ST1 and ST2) and two pairs of distinct poroids. ST3 and ST4 on separate platelets. A pair of small poroids accompanies ST4. Genital shield 130 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 3 pairs of poroids around the genital shield. Ventrianal shield subtriangularshaped, 127 long and 112 wide (at level of ZV2), faintly striate, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2), and a pair of large and circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 66 long, lightly serrated. Primary metapodal plate or inguinal sigillum 22 long and 11 wide.

Spermatheca ( Figure 28c ) — Cervix 4 long, Ushaped.

Chelicera ( Figure 28d ) — Seven teeth and a pilus dentilis on the fixed digit. Movable digit 37 long, bidentate.

Legs ( Figure 28e ) — Measurements of legs: leg I 422; leg II 313; leg III 314; leg IV 362. Eight setae (2-2/1, 2/0-1) on the genu II. One macroseta (not reported on the original description), 33 long, on the genu III. Three other pointed macrosetae, 54, 34, 67 long, on genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype deposited in Museum of Zoology of University of Navarra (MZUNAV), Spain.

Adult male ( Figure 28f, g )

Male specimen of this species similar to but smaller than the female. Moraza and Peaea-Estevez (2006) described the male of N. ferraguti . However, these authors did not give a complete setal and body measurements. We thus present a complete description of this male.

Dorsal shield — Dorsal shield chaetotaxy similar to the female, with smooth surface: length 322; width 163 (at level of s4), 200 (at level of Z1), with seven pairs of solenostomes: gd1, gd2, gd4, gd5, gd6, gd8, and gd9. Dorsal shield bearing 21 pairs of setae (sub-lateral setae, r3 and R1 on the dorsal shield). All dorsal setae smooth, except Z5 which is slightly serrated: j1 29; j3 36; j4 22; j5 22; j6 25; J2 25; J5 13; z2 11; z3 43; z4 33; z5 24; Z1 25; Z4 55; Z5 68; s4 49; s6 48; S2 50; S4 39; S5 29; sub-lateral setae r3 23 and R1 32. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 28f ) — Sternogenital shield is smooth. Ventrianal shield 135 long and 170 wide, lightly reticulated, bearing seven pairs of preanal setae with two pairs of poroids. Caudoventral seta JV5 42 long, smooth, on the integument surrounding the ventrianal shield.

Chelicera ( Figure 28g ) — Two teeth and a pilus dentilis on the fixed digit. Movable digit 31 long, unidentate. Spermatodactyl L-shaped.

Legs — Measurements of legs: leg I 375; leg II 306; leg III 283; leg IV 355. Three macrosetae, 35, 35 and 50 long, on genu, tibia, and basitarsus IV, respectively.

The male specimen of this species is different from the female by the position of both sub-lateral setae (r3 and R1) (on dorsal shield on the male; on lateral margin on the female), and the number of solenostomes on the ventrianal shield (two pairs on the male; one pair on the female).

Material examined — A male paratype specimen.

Previous reports — N. ferraguti is only known from Tenerife (Canary Islands). It was reported from lichens on dead log, and from soil and litter of Cheirolophus canariensis var. subexpinnatus (Burch.) A. Hansen and Sunding (Asteraceae) .
