Eotetranychus herbicolus n.sp.

( Figs. 2–11 )

Diagnosis — Female palptarsus sensillum thick; peritremes ending in a hook. Male aedeagus bent down, sinuous, distal part tapering.

Palptarsus terminal eupathidium (spinneret) 6.1 long, 3.5 in diameter; two lateral eupathidia 6 and 9 long; solenidion 4.5 long.

Hysterosomal striation transverse. Hysterosomal dorsal setae pubescent, longer than longitudinal distances between bases of consecutive setae: c1 89 (86), 75 (77) apart; c2 89 (84); c3 82 (79); d1 89, 84 (82) apart; d2 89; e1 82, 63 apart; e2 89; f1 79 (82), 61 (63) apart; f2 77 (79); h1 68 (72), 30 (35) apart; h3 23 (26). Paraanal setae h3 located ventrally.

Ventral idiosomal striation transverse; striae on the genital falp and the area immediately anterior transverse.

Leg chaetotaxy, from coxae to tarsi (solenidia in parentheses; in brackets alternate count from paratype):

Leg I 2 – 1 – 9 – 5 – 9 (1) – 13 [14] (1) + 2 duplexes

Leg II 2 – 1 – 7 – 5 – 8 – 13 (1) + 1 duplex

Leg III 1 – 1 – 4 – 4 – 6 [5] – 10 (1) [9 (1)]

Leg IV 1 – 1 – 4 [3] – 4 – 7 – 8 (1) [10 (1)].

Length of body, including gnathosoma, 569, excluding gnathosoma 391; width 275.

Male (n = 1) — Palptarsus terminal eupathidium (spinneret) small, knoblike; two lateral eupathidia 6 and 7 long; solenidion 5 long.

Leg chaetotaxy, from coxae to tarsi (solenidia in parentheses):

Leg I 2 – 1 – 9 – 5 – 9 (3) – 13 (3) + 2 duplexes

Leg II 2 – 1 – 7 – 5 – 8 – 13 (2) + 1 duplex

Leg III 1 – 1 – 4 – 4 – 6 – 10 (1)

Leg IV 1 – 1 – 4 – 4 – 7 – 10 (1)

Aedeagus bent down, sinuous, tapering to a fine end.

Length of body, not including rostrum, 315.

Type material — male holotype and 2 female paratypes, from leaves of a grass, Brachiaria ruziziensis Germain & Evrard (Poaceae) , Ribeirão Bonito, São Paulo, Brazil, 23 April 2004, coll. P.E.B. Paiva, on one microscopic preparation in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo/ ESALQ, Piracicaba, SP, Brazil.

Etymology — The specific designation is made up of the Latin herba, soft usually green vegetation, referring to the host plant, plus the Latin colus, dweller, inhabitant.

Remarks — The aedeagus of the n.sp. resembles that of E. obtusus Meyer, 1965 (however, in E. obtusus ends in a blunt tip) and that of E. roedereri Gutierrez, 1967 . It differs from both in leg chaetotaxy.
