Neoseiulella arinoi Moraza , Peaea-EstØvez and Ferragut 2005: 109-112; Moraza and Peaea-Estevez 2006: 59; Chant and McMurtry 2007: 147.

Adult female ( Figure 16a – e )

Dorsal shield ( Figure 16a ) — Dorsal shield distinctly reticulated throughout: length 409; width 191 (at level of s4) and 202 (at level of Z1). Seven pairs of solenostomes: gd1, gd2, gd4, gd5, gd6, gd8, and gd9. No poroid visible. Sub-lateral setae (r3 and R1) inserted on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth, except for Z4 and Z5 slightly serrated. Lateral setae on small tubercles: j1 34; j3 37; j4 18; j5 20; j6 36; J2 49; J5 12; z2 18; z3 30; z4 42; z5 24; Z1 46; Z4 75; Z5 80; s4 41; s6 52; S2 63; S4 60; S5 47; sub-lateral setae r3 41 and R1 41. Presence of few visible muscles marks (sigilles) on the dorsal shield. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 16b ) — Sternal shield 75 long and 78 wide (at level of ST2), smooth, with two pairs of setae (ST1 and ST2) and two pairs of poroids. ST3 and ST4 on separate platelets, and a pair of small poroids accompanying ST4. Genital shield 122 long and 74 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating genital and ventrianal shields folded undethe genital shield. One pair of poroids close to the genital shield (ST 5) and 1 pair of poroids around the genital shield. Ventrianal shield longer than wide, 141 long and 110 wide (at level of ZV2), faintly striate, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and a pair of circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 62 long, smooth. Dimensions of the primary metapodal plate or inguinal sigillum 37 long and 5 wide.

Spermatheca ( Figure 16c ) — Cervix 4 long, Ushaped.

Chelicera ( Figure 16d ) — Two teeth and a pilus dentilis on the fixed digit. Movable digit 33 long, unidentate.

Legs ( Figure 16e ) — Measurements of legs: leg I 373; leg II 345; leg III 328; leg IV 416. Seven setae (2- 2/0, 2/0-1) on the genu II. One pointed macroseta, 82 long, on the basitarsus IV. On the specimen examined, two other macrosetae, 30 and 36, on genu and tibia IV, respectively. Even if Moraza et al. (2005) draw three macrosetae on the leg IV, they only mentioned in the text, the presence of one macroseta on this leg (on basitarsus).

Material examined — A female paratype deposited in Museum of Zoology of University of Navarra, Spain.

Adult male

Described by Moraza et al. (2005). We were not able to borrow the male type specimen of this species.

Previous reports — N. arinoi is only known from the Canary Islands. It was collected from lichens on dead log, from soil of "lapilli" and litter of Ficus carica (Moraceae) , Castanea sativa (Fagaceae) and Echium virescens D. C. ( Boraginaceae ) ( Moraza et al. 2005).
