Euseius

Euseius stipulatus, from Instituto Valenciano de Investigaciones Agrarias.

Belongs within: Phytoseioidea.

Euseius is a diverse group of predatory mites with tong-like chelicerae (Walter 1999a). Some species are used in the biological control of the citrus thrips Scirtothrips citri (Grout 2001). Notable representatives include E. papayana, characterised by a dorsum bearing several pairs of enlarged sublateral setae and differing from other species in the genus in lacking setae Z1 (Moraes et al. 2001).

Characters (from Walter 1999a): Adult females with 33 pairs of idiosomal setae (setal pattern 1A:9B/JV-3:ZV). Dorsal shield lightly sclerotised, bearing 19 pairs of mostly simple setae; Z4 simple, similar to most other dorsal shield setae; Z5 usually longest seta, often barbed; seta JV3 absent; J2, S2, S4, S5 and ZV3 present; r3, R1 in soft cuticle. Acuminate or spatulate macrosetae on genu, tibia and basitarsus IV. Calyx of spermathecal apparatus tubular or funnel-shaped. Cheliceral digits short and thick, with characteristic tong-like shape; movable digit with small tooth. Ventrianal shield vase-shaped, seta JV1 usually removed from anterior border of shield, usually more or less aligned with JV2 and/or ZV2. Peritreme relatively short, rarely extending far beyond insertion of seta r3.
