Primeiro registro de \ue1caros eriofi\ueddeos (Acari, Eriophyidae) em seringueiras (Hevea brasiliensis Muell. Arg., Euphorbiaceae) da Floresta Amaz\uf4nica, Brasil

Calacarus heveae Feres, 1992 was the first eriophyid mite reported from Hevea brasiliensis Muell. Arg. This mite was first found in northwestern São Paulo State, Brazil. Feres (1998) described two additional species, Shevtchenkella petiolula and Phyllocoptruta seringueirae, from the same host and from same region. The commercial monocultural planting of the Amazonian rubber tree in the northwestern region of São Paulo State started about 18 years ago. In the Amazonian region, the native rubber tree grows dispersed between other plant species. Until now these eriophyids have been collected only on monocultural plantings. This paper reports the occurrence of C. heveae, S. petiolula and P. seringueirae on H. brasiliensis in the Amazonian Forest for the first time. The monocultural method in association with prevailing climatic conditions allows periodic outbreaks of these mites is believed. These new records for those three eriophyid species on rubber trees growing in natural conditions corroborate this hypothesis

Tetrabdella Hernandes & Feres

Tetrabdella Hernandes & Feres n. gen. Type species: Tetrabdella neotropica Hernandes & Feres n. sp. This genus shares all characteristics of the subfamily Spinibdellinae, but can be distinguished from other genera by the following set of characteristics: presence of trichobothriae on tarsi III and IV; two ventral setae on hypostome; genital tracheae well developed; chelicera elongated with reduced scissorlike digits; palpal tibiotarsus with two long end setae; lateral propodosomal setae (ve) present; palpal tibiotarsus expanded distally (truncated). Until more species are described, this genus remains monotypic.Published as part of Hernandes, Fabio A. & Feres, Reinaldo J.

Immatures There are 4 immature stages in Tetrabdella neotropica n. sp., which differ mainly on the numbers of genital and aggenital setae (Figs. 11–13, Table 4), number of leg setae (Table 1), and adoral setae on hypostome (Table 4). tritonymph: 4 pairs of genital setae on genital valves, the anterior pair slender; 9 pairs plus 2 unpaired aggenital setae between coxae IV; deutonymph: 1 pair of genital setae on genital valves; 5 pairs plus 1 unpaired aggenital between coxae IV; protonymph: no seta on genital valves; 3 pairs plus 1 unpaired aggenital seta between coxae IV; larva: neither genital valve, genital nor aggenital setae present. Dorsum and gnathosoma are similar to described for adult, except for the smaller size and propodosomal striae that are thinner and continuous in immatures (rather than sparsely broken like in adults). Larva bears only one pair of minute adoral setae at tip of hypostome (2 pairs in subsequent stages). Venter of hypostome bears two ventral pairs in all stages. Additional differences are shown in Table 4. Stage Leg coxa trochanter basifemur Telofemur genu tibia tarsus Diagnosis This new species shares many similarities with Spinibdella mali Jorgensen (1967: 98): longitudinal striae sparsely broken on central region of propodosoma, with irregular small lobes (Fig. 16); 4 setae on palp femur and 5 setae on palp tarsus; central region of hysterosoma with transverse striae; lateral hysterosoma with longitudinal striae; two pair of eyes separated by diagonal striae. It can be distinguished by the latter by having trichobothria present on tarsi III and IV, 8 setae on each genital valve (rather than 6 as in S. mali), and by the chaetotaxy of tarsi. Leg chaetotaxy, body dimensions and length of dorsal setae are shown on Tables 1, 2 and 3, respectivelly. The specimens present asymmetry in leg chaetotaxy (Table I). *without rostrum; ** Palpal segments I–V: trochanter, basifemur, telofemur, genu and tibiotarsus, respectivelly. Remarks The specimens were found mostly at the base of rubber tree leaflets, inside a silken cocoon where they probably moult (Hernandes & Feres 2006). A similar moulting behavior is reported for Spinibdella cronini (Baker & Balock) and Biscirus thori Womersley in woodlands, forests and grasslands of Australia (Wallace & Mahon 1972). According to Hernandes & Feres (2006) T. neotropica occur in large number at the transition from the dry to the rainy season (October to January) in the northwestern region of the State of São Paulo, Brazil. In the laboratory, they were observed feeding on Tetranychus ogmophallos Ferreira & Flechtmann (Acari: Tetranychidae), a pest of Arachis hypogaea L. (peanut) and A. pintoi Krapov & Gregory (ornamental plant). Type material Holotype male (n. 6174), Hevea brasiliensis, 18.XII. 2002, Cedral (20 o 55 ’ 30 ’’S, 49 o 26 ’ 49 ’’W), São Paulo, Brazil.

Etymology The generic designation refers to the four trichobothriae, on tarsi III and IV, unique character of the new genus; and the species neotropica, refers to the Neotropical region, where this species was collected.Published as part of Hernandes, Fabio A. & Feres, Reinaldo J.
