Neoseiulini

Dorsal shield (left) and ventral surface of Paragigagnathus strunkhovae, from Chant & McMurtry (2003).

Belongs within: Phytoseioidea.
Contains: Neoseiulus.

The Neoseiulini are a group of mostly relatively conservative predatory mites, most of which are placed in the large genus Neoseiulus. The basal species Evansoseius macfarlanei differs from other members of the tribe in the presence of setae J1 and J4 and the absence of seta R1 (Chant & McMurtry 2003).

Characters (from Chant & McMurtry 2003): Dorsal shield longer than wide; posterior margin rounded, without marked indentation at level of seta S5; usually but not always sculptured/ reticulated/ imbricated. Lateral dorsal setae other than Z5 and sometimes Z4 approximately subequal, without great disparities in length; setae z2 and z4 never, and dorsocentral setae usually not, minute; dorsal setae usually setiform, at most lightly serrated; setae j5, J2, Z1, S4 and S5 always present; seta r3 and usually R1 inserted on lateral integument of female. Female sternal shield usually longer than wide, with posterior margin usually concave or straight, often reticulated or striated; seta St3 usually inserted on shield, occasionally inserted on separate platelet. Female genital shield relatively narrow, posteriorly truncate, with genital seta, sometimes reticulated; usually about the same width as ventrianal shield. Female ventrianal shield usually longer than wide, sometimes extremely so; usually with three pairs of preanal setae, JV1, JV2 and JV3, arranged in broad triangular pattern, and pair of pores widely or narrowly spaced; never vase-shaped; caudoventral area around shield usually with setae JV4, JV5, ZV1 and ZV3. Extensive sexual dimorphism in caudoventral setation present. Peritreme usually extending to level of setae j1/j3, occasionally shorter; peritremal shield narrow, fused anteriorly with dorsal shield, without ecta strip. Chelicera of normal size; fixed digit of female chelicera usually with five or fewer teeth or, if multidentate, with teeth evenly distributed along distal two-thirds of fixed digit; movable digit with 0-3 teeth, most commonly one. Leg I always and legs II-III usually without significant macrosetae. Leg IV with 0-3 macrosetae, most commonly one (Bt).
