ABSTRACT

Two new species of Tydeidae are described, Brachytydeus lorenzatus sp. nov. and Quasitydeus feresi sp. nov. Brachytydeus lorenzatus sp. nov. differs from B. aegyptiaca (Rasmy & El Bagoury, 1979) by having a reticulated area on the region of f1 and f2 , dorsal setae smooth, solenidion (I shorter than or equal to the width of tarsus I, most setae on dorsal shield shorter than the length between their bases and setae d forked distally. The new species is distinguished from B. scutatus Silva, Rocha & Ferla, 2013 by having a slightly reticulate area on the aspidosoma, near setae bo , all dorsal setae slender and club-shaped. Quasitydeus feresi sp. nov. differs from the only other species of the genus, Q. ricensis (Baker, 1970), by having all dorsal setae simple and serrated, similar in shape. Eleven tydeoid species are reported also from several plants native to the state of Rio Grande do Sul, Brazil. This is the second species of Brachytydeus Thor, 1931 described from and the second species described for Quasitydeus Kaźmierski, 1996.

Species of Tydeidae and Triophtydeidae are widely distributed in the world, with the exception of Antarctica. These soft-bodied mites have idiosoma striated and sometimes reticulated or complex, with two prodorsal trichobothria (Kaźmierski 1998Kaźmierski A (1998) Tydeinae of the world: generic relationships, new and redescribed taxa and keys to all species. A revision of the subfamilies Pretydeinae and Tydeinae (Acari: Actinedida: Tydeidae) - part IV. Acta Zoologica Cracoviensia 41: 283-455.). Species of this group present movable cheliceral digit relatively short and needle-like, fixed digit of chelicera reduced and cheliceral bases fused (Kaźmierski 1998Kaźmierski A (1998) Tydeinae of the world: generic relationships, new and redescribed taxa and keys to all species.

They can be associated with plants and inhabit several environments, such as moss, litter, straw, soil or humus, fungi, bird nests, stored food products and arboreal (on plants) (Walter et al. 2009Walter DE, Lindquist EE, Smith IM, Cook DR, Krantz GW (2009) Order Trombidiformes, p. 233-420.

). Quasitydeus Kaźmierski, 1996 has included only the type-species, Quasitydeus ricensis (Baker, 1970), from Costa Rica. Here we describe and illustrate Brachytydeus lorenzatus sp. nov. and Quasitydeus feresi sp. nov. and provide new records of Tydeidae and Triophtydeidae for the State of Rio Grande do Sul, Brazil.

MATERIAL AND METHODS

The study was carried out in Arroio do Meio (29°24'48"S, 51º55'06"W), Colinas (29°24'05"S, 51°53'19"W), Lajeado (29°25'47"S, 51°56'32"W), Muçum (29°07'97"S, 51°50'29"W), Taquari (29°49'04"S, 51°51'34"W), municipalities of the state of Rio Grande do Sul, Brazil.

All mites were collected from leaves of Annona neosalicifolia H.Rainer (Annonaceae); Eupatorium sp. (Asteraceae); Acalypha multicaulis Müll.Arg. (Euphorbiaceae); Byttneria australis St.-Hil., Luehea divaricata Mart., Pavonia sepium A.St.-Hil. (Malvaceae); Trichilia elegans A. Juss., Trichilia claussenii C.DC. (Meliaceae); Morus nigra L. (Moraceae); Myrciaria plinioides D. Legrand (Myrta ceae); Piper aduncum L., Piper amalago L. (Piperaceae); Allophylus edulis (A.St.-Hil., Cambess. & A. Juss.), Cupania vernalis camb. (Sapindaceae); Chrysophyllum gonocarpum (Mart. & Eichler) Engl. (Sapotaceae); Cestrum strigillatum Ruiz & Pav. (Solanaceae).

Four collecting sites were evaluated: three in the municipality of Tramandaí: sand dunes (Site 1: 29°58'56"S 50°07'46"W), containing the natural features of most sandy beaches, with continuous input of sands carried by prevailing winds; mangrove or swamp area (Site 2 - 30°03'02"S 50°13'28"W) and Northern Coast forest (Site 3: 30°04'50"S, 50°12'29"W), with representative regional ecosystem. In Osório, the area evaluated was Morro da Borrúsia (Site 4: 29°52'58"S, 50°17'37"W), within the Atlantic Forest Domain, representing the rainforest ecosystem (Rocha et al. 2015Rocha MS, Silva GL, Silva JO, Freitas EM, Ferla NJ (2015) Phytoseiid mites (Acari: Phytoseiidae) in the northern coastal region of the Rio Grande do Sul State, Brazil. Neotropical Biodiversity 1: 22-35.).

Mites were collected from plants by hand with a fine-tipped paintbrush and were mounted with Hoyer's medium on microscopic slides (Jeppson et al. 1975Jeppson LR, Keifer HH, Baker EW (1975) Mites injurious to economic plants. Berkeley, University of California Press, 641p.). They were dried on a slide warming plate, ringed with nail polish and their morphological details were studied under a phase contrast microscope. Drawings were made using a camera lucida and the lines were digitized using Corel Draw X5(r). For the descriptions, dorsal setal notations follow Kaźmierski (1989Kaźmierski A (1989) Morphological studies on Tydeidae (Actinedida; Acari). I. Remarks about the segmentation, chaetotaxy and poroidotaxy of idiosoma.

). Measurements are given in micrometers (μm) and measurements of the holotypes or illustrated specimens are shown in bold followed by the mean and range in parentheses. The legs were measured from the base of the trochanter to the end of the apotele.

Voucher specimens of each species were deposited in the mite reference collection of the Museu de Ciências Naturais of Centro Universitário UNIVATES (ZAUMCN), Lajeado, Rio Grande do Sul.

TAXONOMY

Eleven tydeoids were on several native plants. They belong to six genera of Tydeidae within the Tydeinae (eight species), Pretydeinae (two species) and one species of the Triophtydeidae. The most abundant genus was Brachytydeus (four species), followed by Tydeus (three species) and Pretydeus (two species).

Etymology. The new species was named in honor of Dorvalino Lorenzato, an eminent agronomist and acarologist who lived at the end of 20th century.

Remarks. The decision to classify this new species in Brachytydeus was made based on the fact that it has 10 pairs of setae (ps included) on the opisthosoma, palpal femurogenu with two setae, having one seta on trochanter I, tibia III and IV each with two setae, femur III with two setae and setae ft "( present on tarsus I (Kaźmierski 1998Kaźmierski A (1998) Tydeinae of the world: generic relationships, new and redescribed taxa and keys to all species.

Type material. Site 3: Holotype female, Brazil, Rio Grande do Sul, Tramandaí (30º04'50"S, 50º12'29"W), 15 August 2011, on Eupatorium sp. One paratype female, same data as holotype.

Etymology. The new species was named in honor to Reinaldo José Fazzio Feres, an eminent Acarologist of Brazil.

Locality of the examined species: Brazil, Rio Grande do Sul state: Site 3: Eupatorium sp. VIII-2011(2).

Remarks. Based on André (1981aAndré HM (1981a) A generic revision of the family Tydeidae (Acari: Prostigmata). II. Organotaxy of the idiosoma and gnathosoma. Acarologia 22: 31-40., bAndré HM (1981b) A generic revision of the family Tydeidae (Acari: Prostigmata). III. Organotaxy of the legs. Acarologia 22: 165-178.), the chaetotaxy of the legs and genital parts are the most important characters in the identification of genera and species. The classification of the new species in Quasitydeus is consistent with the following characters it displays: absence of setae on trochanter III, femur II with three setae and femur III with one seta (Kaźmierski 1998Kaźmierski A (1998) Tydeinae of the world: generic relationships, new and redescribed taxa and keys to all species.
