This species is named in honor of “Instituto Biológico de São Paulo”, a renowned Brazilian institution where the type specimens of this species were collected and which has contributed for many years to the development of agriculture in Brazil. Remarks: This new species could be classified in the peruvianus species group (Chant & McMurtry 2005 b) by having a macroseta on genu I. However, it differs from the species listed by Chant & McMurtry (2005 b) in this group by having an elongate dorsal shield. It resembles several species of the belizensis subgroup of the belizensis species group (Chant & McMurtry 2005 b), mainly Proprioseiopsis asetus (Chant), P. caliensis (Moraes & Mesa), P. mexicanus (Garman), P. miconiae (Moraes & Mesa), P. lineatus (Wu & Lan) and P. weintraubi (Chant & Hansell), by the similar lengths of the dorsal shield setae and macrosetae of leg IV, shape of dorsal and ventral shields, smooth texture of dorsal shield and, except P. asetus and P. mexicanus, shape of the spermatheca. However, the new species differs from the former four species by having seta j 1 about as long as j 3 (j 3 distinctly longer than j 1 in those species). In addition, it differs from P. asetus and P. mexicanus by having calyx of spermatheca sacullar (cup-shaped in those species), from P. caliensis and P. miconiae by having setae s 4, Z 4 and Z 5 about 1.4 times longer and sternal and genital shields distinctly more reticulated, and from P. lineatus and P. weintraubi by having sternal and genital shields reticulated and preanal pores mesad and transversely aligned with the bases of setae JV 2 (sternal and genital shields smooth and pre-anal pores posterior and longitudinally aligned with the bases of setae JV 2 in those species).Published as part of Lofego, Antonio C., Demite, Peterson R., Kishimoto, Raquel G. & De, Gilberto J., 2009, Phytoseiid mites on grasses in Brazil (Acari: Phytoseiidae), pp. 41-59 in Zootaxa 2240 on pages 51-53, DOI: 10.5281/zenodo.19052

Etymology. The name imparisetosus refers to the presence of unpaired setae in the dorsal shield. Remarks. The identification of some dorsal shield setae in this study is provisional, because of their unique position within the phytoseiids. One of the uncertainties refers to the identity of the seta called x in this paper. Is that a podonotal or opisthonotal seta? That seta, observed in the examined deutonymphs and adult females, could actually correspond to J1. Supportive of this interpretation is the absence of this seta in some specimens and the occurrence of two x setae in one of the specimens collected. The very anteriad position of x in relation to what would be expected for the normal position of J1 argues against that interpretation. Also against this interpretation is the fact that in Ascidae sensu Lindquist & Evans (1963), a group taxonomically close to the phytoseiids (see Lindquist et al., 2009 and Famah-Sourassou et al., 2015), J1 normally first appears in the protonymphal stage, whereas in the taxon here described it appeared only in the deutonymphal stage. Thus, we could conclude that the most anterior unpaired seta is podonotal, occupying the same location as the unpaired podonotal setae found in Spadiseius calyptrogynae Lindquist & Moraza (Melicharidae) (Lindquist & Moraza, 2008). The fact that this seta is not found in Spadiseius spathiphyllae Lindquist & Moraza suggests its instability in different species of that genus (and perhaps in the genus here described). Alternatively, if that seta is really J1, it would be necessary to argue that the strong lateral compression of the dorsal shield caused disturbance to the normal chaetotactic pattern, leading to the appearance of J 1 in the deutonymphal rather than in the protonymphal stage. The tendency towards evolutionary loss of J1 could also explain its instability in the deutonymph and adult. It could be argued that the seta interpreted as S 2 in this work is actually S3, because of the position. A point against that interpretation is that S3 has never been reported for phytoseiids. Its first appearance in the deutonymphal stage makes its identification more difficult because in Ascidae sensu Lindquist & Evans (1965) S2 first appear in the protonymphal stage, whereas S3 first appear in the larval stage. The actual absence of S5 is supported by the fact that the usual position of this seta is posterolaterad of the pore located anterolaterally of Z5 (idm5 of Athias-Henriot, 1969). Wide variation is observed among Amazoniaseius imparisetosus n. sp. specimens in relation to the absence of some opisthonotal setae (all of which inserted behind J2): X in five specimens, one J 5 in two specimens, X and one J 5 in one specimen, one S 4 in two specimens, one Z 4 in three specimens, and one Z4 and one S 4 in one specimen. Intra-specific variations as presence or absence of setae, place of insertion of setae, lengths of setae etc., have been reported for other species (e.g. Kolodochka, 1995; Demite et al., 2008; Toyoshima & Amano, 2013; Tixier et al., 2016). The idiosomal setal pattern of the new taxon here described has never been reported in Phytoseiidae. On the ventral surface of the idiosoma, the absence of all ZV setae has not been previously reported. Thus, our interpretation of the dorsal idiosomal setae in the new taxa here described leads us to propose a new setal pattern for the phytoseiids: 13A+x:8F+X/JV-3,4:ZV-1–3.Published as part of Demite, Peterson R., Cruz, Wilton P. & Moraes, Gilberto J., 2017, Amazoniaseius imparisetosus n. sp., n. g.: an unusual new phytoseiid mite (Acari: Phytoseiidae) from the Amazon forest, pp. 302-310 in Zootaxa 4236 (2) on pages 304-305, DOI: 10.11646/zootaxa.4236.2.5, http://zenodo.org/record/32177

The presence of <i>J4</i> is reported for the first time in Typhlodrominae, whereas the absence of all <i>ZV</i> setae is reported for the first time in Phytoseiidae. Within this subfamily, this genus is placed in Paraseiulini (Wainstein, 1976) by the presence of <i>z6</i> and <i>S4</i>, but it differs from the other genera in this tribe by the presence of the unpaired setae and <i>J4</i>, by the absence of <i>S5</i>, <i>JV4</i> and <i>ZV</i>, by the narrow dorsal shield and the presence of anal shield.</p> <p> A long seta <i>J5</i> is not a common characteristic in this family; <i>J5</i> as long as <i>Z5</i> has been reported for <i>Macrocaudus</i> Moraes, McMurtry & Mineiro (Amblyseiinae), but even in that case, those setae are shorter than the distance between their bases (Moraes <i>et al</i>., 2003). A broadly rounded posterior margin of the genital shield has been reported for <i>Amblyseiella</i> Muma and <i>Phytoseiulus</i> Evans (Amblyseiinae), but apparently for none of the Typhlodrominae genera. Among the phytoseiids, the presence of extra unpaired dorsal setae of the idiosoma has not been reported. However, a single seta anteriad of <i>J2</i> has been reported in some specimens of <i>Australiseiulus angophorae</i> (Schicha) (Typhlodrominae), whereas in other specimens two setae or none have been found (Schicha, 1981); other species of the same genus do not have that seta, interpreted by Beard (1999) as <i>J1</i>. Other phytoseiids reported to have seta <i>J1</i> belong to the Amblyseiinae, namely <i>Chileseius</i> Gonzalez & Schuster, <i>Diaphoroseius</i> Chant & McMurtry, <i>Evansoseius</i> Sheals and <i>Rubuseius</i> Ragusa, as well as a few species of <i>Typhodromalus</i> Muma and <i>Typhlodromips</i> De Leon (Chant & McMurtry, 2007). <i>Australiseiulus poplar</i> Beard has a <i>J</i> seta interpreted by Beard (1999) as <i>J4</i>. In comparison with some specimens of <i>Arrenoseius palustris</i> (Chant) and with <i>Macrocaudus multisetatus</i> Moraes, McMurtry & Mineiro, the only phytoseiid species (Amblyseiinae) reported to have <i>J3</i> (Moraes <i>et al</i>., 2003; Chant & McMurtry, 2007), and with species of the closely related family Blattisociidae (Lindquist & Evans, 1965), it seems that this seta could instead be <i>J3</i>. Seta <i>J4</i> has been reported in several phytoseiid genera (all Amblyseiinae), namely <i>Evansoseius</i>, <i>Pararrenoseius</i> Chant & McMurtry, <i>Rubuseius</i>, as well as in <i>Chileseius camposi</i> Gonzalez & Schuster, <i>M</i>. <i>multisetatus</i>, <i>Typhloseiella perforata</i> (Wainstein) and some specimens of <i>A</i>. <i>palustris</i> (Chant & McMurtry, 2007).</p> <p> Extra setae are quite commonly found in other mesostigmatid mites, including species of Ascidae, Blattisociidae and Melicharidae (Moraes <i>et al</i>., 2016) and Laelapidae (Evans & Till, 1966). Most often, extra setae are found in only some of the species of each genus. Thus, other species of this new genus may lack the setae here referred to as <i>x</i> and <i>X</i>.</p>Published as part of <i>Demite, Peterson R., Cruz, Wilton P. & Moraes, Gilberto J., 2017, Amazoniaseius imparisetosus n. sp., n. g.: an unusual new phytoseiid mite (Acari: Phytoseiidae) from the Amazon forest, pp. 302-310 in Zootaxa 4236 (2)</i> on pages 303-304, DOI: 10.11646/zootaxa.4236.2.5, <a href="http://zenodo.org/record/321772">http://zenodo.org/record/321772</a>

Type deposition — Holotype female and three paratypes female: Natividade da Serra (21°21’28"S; 45°17’33"W), Sªo Paulo State, Brazil, on Cecropia sp. (Cecropiaceae), July 26, 2008, P.R. Demite and A.C. Lofego collectors, deposited at Departamento de Zoologia e Botânica, UNESP – Universidade Estadual Paulista, Sªo JosØ do Rio Preto, SP, Brazil; One paratype female, same locality, host, data and collectors as holotype, deposited at Departamento de Entomologia e Acarologia, Universidade de Sªo Paulo, Escola Superior de Agricultura "Luiz de Queiroz" (ESALQ/USP), Piracicaba, SP, Brazil. Etymology — The specific name refers to character "Jeca Tatu" created by the Brazilian writer Monteiro Lobato (1882-1948). This character, one of the most important of this writer, lived in rural areas of the region where this species was found. Remarks — This new species belongs to peruanus species group (Chant and McMurtry, 2003) which is characterized mainly by having almost all dorsal setae approximately subequal; the fixed digit of chelicerae with more than seven small teeth and movable digit bidentate; ventrianal shield much longer than wide with a slight waist, with three pairs of preanal setae arranged in a triangular pattern, and with a pair of minute pores posterior and mesad of setae JV2. This group was previously represented by two species, Neoseiulus peruanus (El-Banhawy, 1979) and Neoseiulus irungus (El-Banhawy and Knapp, 2011), with register in South America and Africa, respectively. The new species differs from both by having ventrianal shield smooth and calyx of spermatheca cupshaped. N. peruanus and N. irungus has a striated ventrianal shield and a trumpet-shaped and bellshaped calyx, respectively. Nothing is known about biology or ecology of this new species.Published as part of Lofego, A. C., Demite, P. R. & Calvalcante, A. C.

Paratypes: 2 ♀ (specimen numbers T-MZLQ 3013, T-MZLQ 3014): Ilha do Cardoso, Cananéia (25 °04S; 47 ° 55 W), São Paulo State, Brazil, on Blepharocalix salicifolius (Kunt) O. Berg (Myrtaceae), 16 July 2012, deposited at Departamento de Entomologia e Acarologia, Escola Superior de Agricultura “Luiz de Queiroz”(ESALQ), Universidade de São Paulo (USP), Piracicaba, São Paulo State, Brazil. All specimens collected by P. R. Demite. Etymology. This species is named after the eminent acarologist Ronald Ochoa, USDA, USA. Remarks. Nothing is known about the feeding behavior of this species. Tarsonemini species are known as egg parasitoids, algivores, fungivores or phytophages (Lindquist 1969, 1986; Lofego et al. 2005). The feeding habits of species of the genera morphologically most similar to Kaliszewskia are also inadequately known. Fungitarsonemus species have been speculated to feed on fungi, which could also be the case of the species here described, given that the habitats where the types were found are humid, allowing easy development of fungi on leaves. Species of Ceratotarsonemus, Daidalotarsonemus and Rynchotarsonemus are also thought to feed on algae, lichens or on plant leaves.Published as part of Lofego, Antonio C., Demite, Peterson R. & Moraes, Gilberto J., 2015, A new genus and species of Tarsonemidae (Acari: Heterostigmata) from the Atlantic Forest, Brazil, pp. 561-568 in Zootaxa 3986 (5) on pages 563-567, DOI: 10.11646/zootaxa.3986.5.3, http://zenodo.org/record/24296
