A revision of the Plateremaeidae (Acari: Oribatei)

Abstract

The family Plateremaeidae is revised, and includes the following taxa: Plateremaeus Berlese, with the only species P. ornatissimus (Berlese), from Brazil; Allodamaeus Banks, with the species ewingi (Banks), from the USA, coralgablensis, sp. n. (type-locality: USA, Flórida, Coral Gables), and ornatos Balogh & Csiszár, from Argentina; Lophoremaeus, gen. n., with two species: mirabilis Csiszár, from Bulgaria, the type-species, and laminipes (Berlese), n. comb., from Italy; Paralopheremaeus, gen. n., with the species legendrei (Balogh), n. comb., from Madagascar; Calipteremaeus, gen. n., with the species yaginumai (Aoki), n. comb., from Japan; the following species are considered incertae sedis: Plateremaeus carinulatus (Berlese), from Brasil, P. complanatus (Berlese), from Chile, P. rotundatus Berlese, from Japan, and P. tunicatus ( Balogh, from Zaire.<br>A família Plateremaeidae é revista, e inclui os seguintes táxons: Plateremaeus Berlese, com a única espécie P. ornatissimus (Berlese), do Brazil; Allodamaeus Banks, com as espécies ewingi (Banks), dos Estados Unidos, coralgablensis, sp. n.

Description of Lyrifissella gen. n. and Lyrifissellidae fam. n. (Acari, Oribatei)

“…ps3 dorso-lateral, anterior to r2; ip long reaching notogastral margin; epimeral formula 3 : 1 : 3 : 3 ; genitoanal chaetotaxy 7 -1 -2 -3 ; anal and genital plates fused together; ag below unifying point of genital and anal plates; genital setae not ali equidistant; three strong claws with serrulate outer ll1argins; tarsi pedicels not too short. It can be sepparate from L. lato clava by the following characteristics: smaller species (500 j13gainst 784 j1); notogaster reticulate with hexagonal foveae presentinglarge, dark microtubercles at central portion, becoming irregular laterally; prodorsum also reticulate , irregular; sensillum with large, flat, almost rounded on the exact nature of the Plateremeidae and related families, which only recently was ordered by Paschoal (1979Paschoal ( , 1987 . The first to question P. vestitus as a true Plateremaeus were 8alogh (i 962) and Cziszár & Jeleva (1962), who also guessed that it could be cogeneric with Pedro cortesia Hammer; they failed, however, to precise its proper taxonomic position.…”

Description of Nooliodes gen. n. and Nooliodidae fam. n. (Acari, Oribatei) from Madagascar

“…Discussion -[n Balogh, 1962 original description of N. glaber, very peculiar features were noticed namely: the absence of epimeral neotrichy; eight pairs of genital setae; three pairs of anal setae; sensillum not flagellate ; and the genitoanal cuticular ornaments, which were enough characteres to exclude it from Plateremaeus. Due to the lack of a better understanding of this genus, which only very recently was reviewed by Paschoal 1979Paschoal , 1987b,N. glaber was described as a Plateremaeus by Balogh.…”

Recharacterization of Gymnodamaeoidea and erection of Plateremaeoidea (Acari, Oribatei), with key to families and genera

“…Leg articulations on proximal -sockets, i. e., sockets on proximal ends of tarsi, tibiae and genua; Tr and Fe -Tr articulations of legs I, II outside acetabula; femofemora proximal portion after trochantera articu lation almost, straight; femoral and trochanteral tracheae present; with tree small, median or large claws, the middle claw generally larger than the laterais tarsi pedicels present, narrow; Ts I famulus enclosed or free; p Ts I an euphatidium; omega 1 Ts I paraxial, larger than omega 2, both set on a distal apophysis; tibial apophysis I short , median or large , bearing two solenidia; fil Tb I long, antixial; fi2 short, paraxial, femora not bulbous; Ts II with two close solenidia; pl'Ts III absent or present; pI' Ts IV absent; (it) Ts IV absent or present. Leg chaetotaxy: Recognised families -Plateremaeidae Tragardh, (PASCHOAL 1979(PASCHOAL , 1987a; Pheroliodidae Paschoal, (PASCHOAL 1987b); Noo!iodidae Paschoal, (PASCHOAL, 1989d); Hammeriellidae Paschoal, (PASCHOAL, 1989a); Lyrifissellidae Paschoal,(PASCHOAL,198ge) …”
