Oribatid Mite Species

Five oribatid mite species (Oribatida), phoretic on beetles, Aceraius grandis (Coleoptera, Passalidae) from Vietnam, are identified: two new species, belonging to the subgenera Graptoppia (Stenoppia) (Oppiidae) and Perscheloribates (Perscheloribates) (Scheloribatidae), are described; and three known species are Mesoplophora (Parplophora) flavida, M. (P.) polita and Ramusella (Sabahoppia) blattarum. Graptoppia (Stenoppia) luisi sp. nov. differs from all species of the subgenus by the presence of tridentate rostrum. Perscheloribates kontumensis sp. nov. differs from Perscheloribates curiosus Ermilov, 2016, Perscheloribates hanoiensis Ermilov & Starý, 2018 and Perscheloribates surigaoensis Corpuz-Raros, 1980 by the presence of body sculpturing, distinct setiform apex in bothridial setae and flexible notogastral setae. Species M. (P.) flavida, M. (P.) polita and R. blattarum, the subgenera Mesoplophora (Parplophora) and Ramusella (Sabahoppia), and the genera Mesoplophora and Graptoppia are recorded in Vietnam for the first time; the subgenus Graptoppia (Stenoppia) is recorded in the Oriental region for the first time. An identification key to known species of Graptoppia (Stenoppia) is given.

Two new species of oribatid mites of the genus Neoribates (Oribatida, Parakalummidae) are described based on adult specimens from leaf litter in the Montagne d'Ambre National Park of North Madagascar. Neoribates africanus sp. nov. and N. madagascarensis sp. nov. clearly differs from all species of the genus by the absence of interlamellar seta (including alveolus). An identification key and data on distribution and ecology of known African species of Parakalummidae are presented.

Based on material from aquatic habitats in the northern Chihuahuan Desert and a literature review, we present an account on the occurrence of genus Rhinoglena in North America. Two new species are described, and the presence of Rhinoglena frontalis in the USA is confirmed. Of the two new species, R. texana n. sp. is a close relative of R. frontalis, whereas R. ovigera n. sp. is unique by being oviparous, in contrast to all other Rhinoglena which are viviparous. This prompts a revision of the generic diagnosis of Rhinoglena to accommodate the new species. An identification key to the known species of the genus is provided.

The present study is based on oribatid mite materials (Acari, Oribatida) collected from Taiwan in 2009–2010. A list of identified taxa, including 34 species from 30 genera and 21 families, is presented; of these, the subspecies Tectocepheus velatus sarekensis, the species Suctobelbella (Flagrosuctobelba) cf. elegantula, Paralamellobates misella, Protoribates paracapucinus, Perscheloribates nodosus and Scheloribates (Bischeloribates) dalawaeus, the subgenera Uracrobates (Parauracrobates) and Scheloribates (Bischeloribates), and the genera Scapheremaeus and Brassiella are recorded in the fauna of Taiwan for the first time. The species Camisia hamulifera and Fissicepheus defectus are recorded in the Oriental region for the first time. Two new species belonging to the genera Galumna (Galumnidae) and Uracrobates (Mochlozetidae) are described. Galumna (Galumna) tsengi sp. nov. differs from G. (G.) makilingensis Ermilov, Corpuz-Raros & Tolstikov, 2014 by the clavate heads of the bothridial setae, slightly dilated  porose areas Aa in posterolateral parts, not boomerang shaped, and by the erect interlamellar setae, which are shorter than the lamellar setae. Uracrobates (Parauracrobates) newtaipeiensis sp. nov. differs from U. (P.) truncatus Ermilov & Martens, 2015 by the absence of well-developed lateral teeth on the lamellar cusps, foveolate notogaster and anogenital region and the medium length of the anal and adanal setae.

A New Species

A new species and three new records of oribatid mites collected from soil/litter samples of Malappuram Dt. of Kerala, South India, are studied. Indoribates (Indoribates) irumbuzhiensis sp. nov. shares some morphological similarities with I. (I.) hauseri (Mahunka, 1997) and I.(I.) crassisetiger (Fukuyama & Aoki, 2000) described from Borneo and China respectively. However, the larger body size, smooth rostral setae, straight interlamellar setae, long and smooth notogastral setae, barbed/ciliate nature of genital setae, g4 and g5, distally pointed anal and adanal setae, and presence of basiventral tooth on tibia I and II keep its identity separate from the above two species. Identification key to all known species of subgenus Indoribates (Indoribates) is provided. The paper also include three new records of oribatid mites from India viz. Gibbicepheus (Gibbicepheus) kanekoi (Aoki 1958), Yoshiobodes (Yoshiobodes) camerunensis Fernández, Theron, Leiva & Tiedt.,2017 and Eupelops intermedius (Hammer, 1979), of which, Y. (Y) camerunensis is new record for the Oriental Region and first record of the genus from India.

Two new species of the genus Eutegaeus (Oribatida, Eutegaeidae) are described based on specimens from moss in the Queulat National Park of Chile. Eutegaeus aysenensis sp. nov. (description based on the adult, larva, deuto- and tritonymph) is morphologically similar to that of Eutegaeus lagrecai in having long, flagellate interlamellar and notogastral setae and rod-like bothridial seta; it differs from the latter by having smaller body size and comparatively long bothridial seta, the lamella having anteromedial process, and by the absence of striate ornamentation on notogaster. Eutegaeus queulatensis sp. nov. (description based on the adult, proto- and tritonymph) is morphologically similar to that of Eutegaeus membraniger in having a triangular anteromedial lamellar process, long, rod-like bothridial seta, foveate lamella, and dorsal notogastral setae of medium length; it differs from the latter by having smaller body length, thickened notogastral setae, flagellate interlamellar setae, setiform lamellar setae, a tubercle on epimere III, and absence of an anterolateral tooth on the lamella. Based on new information, several characters in the generic diagnosis of Eutegaeus adults are modified or expanded, and a preliminary diagnosis for juveniles is presented. The larva of E. aysenensis sp. nov. is the first to be described for the genus. Nymphs of four species of Eutegaeus are compared.
