Tarsonemidae

Habitus of adult female Coreitarsonemus, with leg IV of male, from Lindquist (1986).


Belongs within: Eleutherengonides.
Contains: Tarsoneminae.

The Tarsonemidae are a family of mites of diverse habits, many of which are phoretic on insects as adult females. Some species of tarsonemid are economically significant phytophages. Members of the subfamily Acarapinae are parasitic at all stages of the life cycle on adult insects. The Pseudotarsonemoidinae, characterised by the presence of three or four pairs of setae on the metapodosomal venter, together with the absence of a membranous ambulacrum on the first leg in females which usually bears a single large sessile claw, are commonly found in association with insects except for the plant-feeding genus Polyphagotarsonemus. They are divided between the tribes Pseudotarsonemoidini and Tarsonemellini, the latter of which is characterised by the presence of a small, flange-like apical process on the palp and greatly elongated cheliceral stylets that occupy the entire length of the gnathosomal capsule when retracted. Acarapinae and Tarsoneminae share only two setae on the metapodosomal venter while the female first leg has a membranous ambulacrum with the claw usually much reduced or absent (Lindquist 1986).

Characters (from Walter et al. 2009): Cheliceral stylophore consolidated with subcapitulum to form capsulate gnathosoma; palpi reduced. Female legs IV three-segmented, usually much more slender than legs II-III, with fused femur and genu, without claws and empodium. Male legs IV three- or four-segmented, always inserted ventrally, with single sessile or vestigial claw; male genital capsule caudal in position.
