New data on ptyctimous mites (Acari, Oribatida) from the Oriental Region, with descriptions of two new species
Systematic and Applied Acarology, 2020Co-Authors: Wojciech Niedbała, Sergey G. ErmilovAbstract:The present study is based on ptyctimous oribatid mite material collected from the Oriental Region (Sri Lanka, Thailand, Malaysia, Indonesia, Macau Peninsula, Taiwan). A list of identified taxa, including 33 species from 15 genera and six families, is presented. Two new species, Euphthiracarus (Pocsia) insperatus Niedbala sp. nov. (Euphthiracaridae) from Indonesia and Hoplophthiracarus paraconcinuus Niedbala sp. nov. (Steganacaridae) from Malaysia are described. Morphological additions to Mesoplophora (Parplophora) brevicarinata, Acrotritia ardua, A. paraardua, A. sterigma, Plonaphacarus kugohi, and P. protrusus are presented. Deuto- and tritonymph of Apoplophora phalerata are described. Mesoplophora (Parplophora) flavida and Indotritia (Indotritia) krakatauensis are recorded for the first time in Sri Lanka, Austrotritia robusta, Sabahtritia sarawak and Phthiracarus pygmaeus in Indonesia, Microtritia minima, Atropacarus (Atropacarus) striculus, Plonaphacarus foveolatus, and P. protrusus in Taiwan. Acrotritia mahunkai and A. paraardua are recorded for the first time in the Oriental Region.

New distributional records and redescriptions of Oriental ptyctimous mites (Acari, Oribatida) of the Oriental Region
Systematic and Applied Acarology, 2007Co-Authors: Wojciech NiedbałaAbstract:Abstract In 25 additional localities from Oriental Region 32 of the hitherto known species of ptyctimous mites (Acari, Oribatida) were collected. The new localities permit a more precise determination of the geographical distribution ranges of eleven species, usually extending their ranges, and prompted change in the zoogeographical element of some species. Additional morphological descriptions for three species, Oribotritia corporaali (Oudemans, 1926), Acrotritia divida (Mahunka, 1991), Notophthiracarus lienhardi Mahunka, 1996 are given.

An illustrated key to the Oriental species of the genus is provided. Eridolius guptai is recorded for the first time from Lao and E. niger is recorded for the first time from Arunachal Pradesh (India).

First record of the genus Amauronematus Konow (Hymenoptera: Symphyta: Tenthredinidae: Nematinae) with three new species from the Oriental Region.
Zoos' Print Journal, 2004Co-Authors: M.s. Saini, V. VasuAbstract:With three new species, the genus Amauronematus Konow is reported for the first time from India and thus it has extended its faunistic limits to the Oriental Region. Described and illustrated in this paper as new are A. dilatus, A. kulwantae and A. tesa. A key for separation of the Oriental species is provided. ABBREVIATIONS AWMT - Apical width of metatibia; EL - Eye length; IATS - Inner apical tibial spur; IDMO - Interoocular distance at level of median ocellus; LID - Lower interocular distance; MB - Metabasitarsus; OATS - Outer apical tibial spur; OCL - Ocellooccipital line; POL - Postocellar line; UCL - Oculooccipital line; UOL - Oculoocellar lineAfter being erected by Konow (1890) the genus Amauronematus was so far recorded from the Holarctic Region only. It is based on Nematus fallax Lepeletier as its type species designated by Rohwer (1911). However, with the discovery of three new species from India, this genus has extended its faunistic limits to the Oriental Region. The new species are described and illustrated on a uniform pattern.

(twelve species) is predominantly an arboreal genus that ranges from India to Queensland, with the majority of species in Malaysia and Indonesia. Rotastruma gen.n. (two species) is known from China, Singapore, and East Malaysia and is also arboreal. Tetheamyrma gen.n. is monotypic and known only from a single leaf litter sample from East Malaysia. The three species of Kartidris gen.n. are terrestrial and have been found in mountainous areas in southern China. Thailand and India.
