Amblyseius djenaeli Kreiter n. sp.

Zoobank: F3A10C4E-9A70-457F-A76D-939A73A17CFF

Diagnosis — Amblyseius djenaeli Kreiter n. sp. belongs to the subfamily Amblyseiinae (absence of dorsolateral setae z3 and s6 and the caudoventral setae JV3), to the tribe Amblyseiini (setae j3, s4, Z4 and Z5 longer than other setae, ratio s4 / Z1> 3.1, many teeth on the fixed cheliceral digits and macrosetae on legs I, II and/or III[?] in addition of macrosetae on leg IV), to the subtribe Amblyseiina (sternal shield as long as wide, ventrianal shield longer than wide, seta J2 present, genital shield almost as wide as ventrianal shield, ventral shields generally smooth, macrosetae on all legs, setae j5, J2, S2, S4, S5 and Z1 present), to the genus Amblyseius (ratio s4 / S2> 3.0, chelicerae of normal size with fixed digit of the same size as movable digit, seta JV2 present, without incision in lateral margin of dorsal shield at the level of seta s4, ventrianal shield not reduced to a simple anal shield, Ge III and Ti III each generally with a macroseta) ( Chant and McMurtry 2007).

Setae J2 and Z1 are present, dorsocentral setae and setae z2, z4, Z1, S2, S4, and S5 are minute, setae s4, Z4 and Z5 are prominent, elongate and whip-like, female ventrianal shield usually pentagonal, as wide at level of anus than at level of setae ZV2 or wider at this later level, which allows to classify this new species in the species group obtusus (Chant and McMurtry 2004a).

Like A. tamatavensis , A. djenaeli n. sp. belongs to the species subgroup aerialis with spermatheca tubular. This subgroup contains 46 species (Chant and McMurtry 2004a). Many of those species are very different from the new species ( Table 18 ).

The type material of the more similar species, A. solani , was requested in Cuba for comparison with A. djenaeli n. sp. without any success.
