Genus Amblyseius Berlese

Amblyseius acalyphus Denmark & Muma

Amblyseius acalyphus Denmark & Muma, 1973: 243; 1989: 75; Moraes et al., 1986: 6; 2004b: 12; Feres & Moraes, 1998: 125; Ferla & Moraes, 2002a: 880; Chant & McMurtry, 2004a: 203; 2007: 74; Lofego et al., 2004: 2; 2009: 42. Amblyseius (Amblyseius) acalyphus . — Denmark & Muma, 1989: 75.

Specimens examined. Pirassununga, April 2001, 2 females on unidentified Asteraceae . Pirassununga, August 2002, 2 females on Myrcia sp.; São Carlos, September 2001, 2 females on Byrsonima intermedia A. Juss. , 2 females on Didymopanax vinosum March. and 1 female on Duguetia furfuracea (A. St. Hal.) Benth. & Hook. f

Previous records. Brazil [States of São Paulo (Moraes et al., 2004b); Mato Grosso (Ferla & Moraes, 2002a) and Minas Gerais (Silva et al., 2010)] and French Antilles (Kreiter et al., 2006).

Remarks. The measurements of six adult females collected fit the original description, except for the shorter Z5 [158 (160–172) for these specimens and 220 in the original description]. This difference was also reported in previous papers (Feres & Moraes, 1998, 2002; Lofego et al., 2004, 2009). The specimens examined in this work have seven and two teeth on the fixed and movable cheliceral digits respectively (these parameters were not previously reported in the literature). In the original description of this species, the illustration of the calyx suggests the existence of a transverse plate-like structure near the mid length of the spermathecal calyx, which was mentioned by Denmark & Muma (1989) and Ferla & Moraes (2002). Observations of specimens collected in this work indicate that the structure corresponds to the end of the calyx next to the vesicle. Thus, what was implied as being a distal continuation of the calyx beyond that structure in the original description corresponds the constricted section of a spermatophore inside the vesicle. Figures 1–3 show spermathecae with apparently containing zero, one and three spermatophores.
