Diagnosis — Females with dorsal shield reticulate, except for a area next to Z4, setae Z4 and Z5 serrate; length of almost all dorsal setae subequal; peritreme extending anteriorly to j1; ventral shields smooth; ventrianal shield much longer than wide with a slight waist; calyx of spermatheca cup-shaped and atrium inconspicuous.
Description. Female (n= 5). Dorsum — Idiosomal setal pattern (Chant and Yoshida-Shaul, 1991): 10A:9B/JV-3:ZV. Dorsal shield reticulate, except for a area next to Z4, 283 291 (283 – 300) long, 170 172 (170 – 175) wide at level of s4; with nine pairs of lyrifissures and six pairs of pores; setae: j1 19 20 (19 – 21), j3 34 34 (31 – 35), j4 24 26 (24 – 28), j5 26 26 (23 – 29), j6 41 41 (38 – 42), J2 45 48 (45 – 50), J5 8 9 (8 – 10), z2 29 32 (29 – 34), z4 36 40 (36 – 42), z5 39 37 (34 – 39), Z1 39 42 (39 – 45), Z4 47 46 (44 – 47), Z5 55 56 (53 – 58), s4 50 51 (50 – 55), S2 45 44 (41 – 46), S4 38 38 (37 – 40), S5 27 28 (26 – 30), r3 30 31 (30 – 32), R1 23 24 (23 – 25). All setae smooth, except Z4 and Z5 slightly serrate.
Venter — Sternal shield with three pairs of setae and two pairs of lyrifissures; distances between st1-st3 60 60 (60 – 61), st2-st2 67 67 (65 – 67); st4 on metasternal plate; Genital shield smooth; distance between st5-st5 65 62 (61 – 65). Ventrianal shield constricted at level of JV2; smooth; 102 106 (102 – 113) long, 68 70 (68 – 71) wide at level of ZV2 and 55 57 (55 – 58) wide at level of anus; with three pairs of pre-anal setae (JV1, JV2 and ZV2) and a pair of minute pores postero-mesad of JV2. Four pairs of opisthogastric setae on unsclerotized cuticle (JV4, JV5, ZV1 and ZV3). Seta JV5 37 38 (36 – 40). All ventral setae smooth. Two metapodal plates visible.
Peritreme — Extending anteriorly to j1.
Spermatheca — Calyx cup-shaped 10 10 (9 – 10) long, atrium inconspicuous.
Chelicera — Movable digit 27 28 (27 – 29) long, with two teeth in addition to apical tooth; fixed digit 29 29 (28 – 30), with 11 10 – 11 teeth in addition to apical tooth. Pilus dentilis not visible.
Legs — Macrosetae present only on leg IV: SgeIV 32 33 (32 – 35), StiIV 26 26 (24 – 28), StIV 58 63 (58 – 67). SgeIV and StIV with knobbed tip. Chaetotatic formula of genu II: 2-2/0-2/0-1 and of genu III: 1- 2/1-2/0-1.
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.
