Taxonomic and faunistic data for seven species of the genus Amphichroum Kraatz, 1857 (Omaliinae) from the Himalayan Region and Tibet are provided. All species are (re-)described and illustrated, including two new species: A. ahrensi sp. n. from India (West Bengal) and A. telnovi sp. n. from western Nepal. A new combination is proposed for A. nepalicum (Coiffait, 1982) comb. n., originally described in the genus Arpedium Erichson, 1839. The lectotype is designated for A. anthobioides Champion, 1925. Distributional distributional maps for all covered species are provided. Amphichroum monticola Cameron, 1928 is recorded from Nepal for the first time.

A New Species

Two new species groups are established for East Palaearctic species of the genus Anthobium Leach, 1819: the atrocephalum group containing the widespread Palaearctic A. atrocephalum (Gyllenhal, 1827), A. formosanum Shavrin, sp. n. (Taiwan), A. hammondi Watanabe, 1990 (Japan), A. lackneri Shavrin, sp. n. (Japan: Hokkaido), and two Chinese species, A. kabateki Shavrin, sp. n. (Yunnan, Gansu) and A. marci Shavrin, sp. n. (Sichuan); the convexior group containing four new species from China: A. convexior Shavrin, sp. n. (Shaanxi, Sichuan), A. auritum Shavrin, sp. n. (Yunnan), A. kabaki Shavrin, sp. n. (Sichuan), and A. semenovi Shavrin, sp. n. (Sichuan). New species are described and illustrated. The species groups are defined, briefly discussed and a key to the species of each group is given. Additionally, a new species of the morchella group, A. inopinatum Shavrin, sp. n. (China: Yunnan) and the nigrum group, A. bengalicum Shavrin, sp. n. (India: West Bengal), are described and illustrated. New faunistic records of A. reflexum (Reitter, 1891) from Kazakhstan, Kyrgyzstan, and Tajikistan are provided.

Two New Species

AbstractSurveys of acephaline gregarines from Nadia district (23°N, 88.5°E) of West Bengal, India revealed the occurrence of two new species of Nematocystis Hessé, 1909; Nematocystis gardenica sp.n. and Nematocystis kalyaniensis sp. n. in the seminal vesicles of earthworms, Amynthas diffriengens (Bairds, 1809) and Amynthas hawayanus (Rosa, 1891), respectively. Trophozoites of Nematocystis gardenica sp. n. are elongate, nematode-like and have parallel sides with pointed tips. Dimensions of trophozoites ranged from 110 to 1320 (505.0 ± 12.0) μm. Dimensions of gametocysts ranged from 140 to 166 μm and the small biconical sporocysts have varying dimensions of 11.0−12.6 μm × 4.0 μm. Trophozoites of Nematocystis kalyaniensis sp.n. are solitary, elongate, nematode-like but have nearly equal bulb-like swellings at two ends, one of which lodges the nucleus. Dimension of trophozoites ranged from 246 to 1232 (565.0 ± 21.0) μm. Dimensions of gametocysts ranged from 120 to 155 μm. Sporocysts are biconical with dimensions of 8.5−11.4 × 5.0 μm.

Two New Species

Two new species of Floridotarsonemus Attiah, 1970 (Acari: Heterostigmatina: Tarsonemidae), F. kukri Karmakar & Mondal sp. nov. and F. kanthali Karmakar & Mondal sp. nov. are described based on the specimens collected from Rhododendron indicum (Ericaceae), Cinchona officinalis (Rubiaceae) and Artocarpus heterophyllus (Moraceae) in Central Himalayan biogeographic province located in Darjeeling and Kalimpong district and Nadia district in the new alluvial zone of West Bengal, India. This registers the first record of Floridotarsonemus from the Indo-Malyan biogeographic realm. A note on the generic diagnosis of Floridotarsonemus and keys to differentiate the species of world Floridotarsaonemus are provided.
