Neoseiulella elisae (Schicha and McMurtry)

( Figure 1 )

Typhlodromus elisae Schicha and McMurtry 1986: 177 ; Chant and Yoshida-Shaul 1989: 1023-1024; Schicha 1987: 152, 154. Typhlodromus (Anthoseius) elisae Schicha and McMurtry Moraes, 2004: 322 .

Adult female ( Figure 1a – d )

Dorsal shield ( Figure 1a ) — Dorsal shield strongly reticulated, more heavily sclerotized on dorsocentral area of the shield: length 485; width 300 (at level of s4 and at level of Z1). Three pairs of solenostomes: gd5, gd8, and gd9 and 1 pair of poroids clearly visible. Sub-lateral setae (r3 and R1) on the lateral margin. Bearing 19 pairs of setae, all dorsal and sub-lateral setae smooth: j1 22; j3 33; j4 18; j5 28; j6 42; J2 55; J5 18; z2 25; z3 25; z4 30; z5 30; Z1 43; Z4 60; Z5 55; s4 43; s6 50; S2 63; S4 55; S5 50; sub-lateral setae r3 38 and R1 40. Peritreme extending anteriorly to level of j1 .

Ventral shields ( Figure 1b ) — Sternal shield lightly reticulated, 70 long and 50 wide (at level of ST2), with three pairs of setae (ST1, ST2 and ST3) and two pairs of small solenostomes. The fourth pairs, the metasternal setae (ST4) on separate platelets. A pair of small pores accompanying ST4. Genital shield lightly reticulated, 145 long and 70 wide (at level of ST5). Four elongate platelets or genital sigilla separating the genital and ventrianal shields not discernible on the specimen examined. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield subtriangular, distinctly reticulated throughout, 143 long and 133 wide (at level of ZV2), with four pairs of preanal setae (JV1, JV2, JV3 and ZV2), and a pair of small circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 50 long, smooth.

Spermatheca ( Figure 1c ) — Cervix 20 long, coneshaped.

Chelicera — Not visible.

Legs ( Figure 1d ) — Measurements of legs: leg I 356; leg II 270; leg III 288; leg IV 388. Seven setae (2-2/0, 2/0-1) on the genu II. Legs much shorter than the dorsal shield and macrosetae only on leg IV, SgeIV: 13, Sti IV: 40 with tip tapered, St IV: 28.

Material examined — The female holotype deposited in the New South Wales Department of Primary Industries , Agricultural Scientific Collections Unit (Acarology), Orange Agricultural Institute , Forest Road, Orange NSW 2800, Australia .

Adult male — The male of this species is unknown.

Previous reports — N. elisae is only known from Western Australia on Eucalyptus sp. ( Myrtaceae ).

We thus consider 44 valid species in the genus Neoseiulella in the followings parts of this paper.
