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).

Two New Species

Two new species of oribatid mites of the subgenus Siculobata (Paraleius), phoretic on Insecta (Coleoptera and Diptera), are described from the U.S.A. and Trinidad, based on adults. Siculobata (Paraleius) americana sp. n. differs from Siculobata (Paraleius) leontonycha (Berlese, 1910) by the presence of monodactylous legs and a slightly modified claw on all pretarsi. Siculobata (Paraleius) trinidadensis sp. n. differs from S. (P.) americana sp. n. by the presence of sublamella, fusiform bothridial seta and a normal claw on pretarsi III, IV, and the absence of pedotectum II. Subgeneric morphological traits and an identification key to known species of Siculobata (Paraleius) are presented.

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

AbstractTwo new species of oribatid mites, Suctobelbella (Ussuribata) phylliformis sp. n. (Suctobelbidae) and Neoribates (Neoribates) paratuberculatus sp. n. (Parakalummidae), are described from ferralitic soil of polydominant forest in Dong Nai Culture and Nature Reserve, southern Vietnam. Suctobelbella (Ussuribata) phylliformis sp. n. is similar morphologically to S. (U.) separata Mahunka, 2001, however, the new species differs from the latter by the number of genital and adanal setae, the morphology of the knob-like tubercle and the number of lateral prodorsal teeth. Neoribates (Neoribates) paratuberculatus sp. n. is similar morphologically to N. (N.) tuberculatus Willmann, 1956, however, the new species differs from the latter by the smaller body size, density of tubercles on pteromorphs and the morphology of bothridial setae. The validity of Suctobelbella (Ussuribata) is discussed; an identification key to all species of this subgenus is given.

Two new species of oribatid mites of the family Lohmanniidae are described from litter in the mixed forest of Zanzibar, Tanzania. Annectacarus tanzanicus sp. nov. differs from Annectacarus vinalesensis Ermilov & Tolstikov, 2015 by body size, the number of neotrichal notogastral setae, porose parts on the notogaster and branches on bothridial setae, and the localization of rostral setae. Strinatacarus zanzibarensis sp. nov. differs from Strinatacarus aelleni Mahunka, 1977 by body surface and length of some notogastral setae. Tritonymphal instar of Annectacarus tanzanicus sp. nov. is also described. An identification key to the known species of the genus Annectacarus from the Ethiopian region is presented.

Key Characters

Two new species of Calocybe (Calocybe erminea sp. nov. and C. badiofloccosa sp. nov.) are described from Liaoning province, China. Calocybe erminea is characterized mainly by its light khaki to dirty white pileus, slightly hygrophanous stipe, small basidiospores and cellular epicutis. The key characters of C. badiofloccosa are its light ocher yellow and rough pileus, villose stipe and large basidiospores. The results of phylogenetic analyses based on the internal transcribed spacer (ITS) and the nuclear large subunit rDNA (nrLSU) region indicated that they belong to Calocybe, but they are distinct from other species in the genus. They are compared morphologically with other species which are phenotypically similar and the phylogenetic relationships between them and allied taxa are discussed. These results confirm the species is new to science.
