Phytoseiid mites (Acari: Phytoseiidae) found in soil and litter from Atibaia, State of São Paulo, Brazil, with description of two new species

First Record of <i>Protogamasellus mica</i> (Athias-Henriot) (Acari: Mesostigmata: Ascidae) from Japan, with a Description of the Male

“…However, it is not certain whether this conclusion was based on the observation of type specimens of P. mica or voucher specimens identified as P. mica. Furthermore, Lindquist (1965) examined the holotype of P. mica, and concluded that P. mica is conspecific with and a senior synonym of P. primitivus, as indicated by Evans (1982) (Mineiro et al, 2009). Therefore, in the present study we follow Evans (1982) and describe the present materials as P. mica.…”

“…Distribution. This species has been recorded from North Africa (Athias-Henriot, 1961), Europe (Evans, 1982), Russia (Ghilarov and Bregetova, 1977), the U.S.A. (Walter and Kaplan, 1990), Australia (Halliday et al, 1998), Brazil (Mineiro et al, 2009), and Iran (Kazemi and Rajaei, 2013) as P. mica. Additionally, the species has been recorded from Europe, Asia, and South Africa under the name P. primitivus (Karg, 1962(Karg, , 2007Genis et al, 1967).…”

A new genus of mites of the subfamily Platyseiinae associated with Azteca ant galleries in Cecropia trees in Costa Rica (Acari: Mesostigmata: Blattisociidae)

“…As in the new taxon, a weak or indiscernible sclerotization of the calyx region, along with a diverticular lobe where the minor duct is connected, has been noted or illustrated for species of Platyseius (Lindquist 2003), and also for Cheiroseiulus reniformis (Evans & Baker 1991, Lindquist 2003; although a minor duct wasn't discerned for the latter, one is present in the undescribed form of Cheiroseiulus at hand. Other than the description and illustrations for two species of Cheiroseius from South Africa by Jordaan et al (1987) and one from South America by Mineiro et al (2009), the spermathecal apparatus has been ignored in descriptions of well over 100 other species in other parts of the world. Typically, among females of many species of Cheiroseius we have examined, a sclerotized calyx is present, from which a long, minor duct emanates and extends into a mass of convolutions, as shown to some extent by the figures of Jordaan et al (1987).…”

“…(=H.) americanella (De Leon, 1964) (EEL personal observations), and L. elegans Naeem et al and L. chelaserratus Naeem et al, 1985), or that seta may be whip-like and pd-2, as in L. peterfuldi (Ohmer et al 1991); tarsus II may be the only tarsus with a modified (whip-like) seta, but it is pl-2, as in several other species of Lasioseius (Mineiro et al 2009, Brito et al 2011; or setae (d-2) may be long and attenuated but not strap-like, not distinctly different from adjacent tarsal setae (EEL, unpublished observations). A similar convergence is seen in the monobasic blattisociine genus Arrhenoseius, in which the elongated strap-like setae are ad-2 on tarsi II to IV and pl-2 on tarsus IV (there being only one such seta on tarsus III) (Walter & Lindquist 2001).…”
