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.

Observations on two new species of Monocystis Stein, 1848 (Protozoa: Apicomplexa: Monocystidae) Monocystis darjeelingensis sp.n. and M. ranaghatensis sp.n. from earthworms (Annelida: Oligochaeta) of West Bengal, India

AbstractSurveys of acephaline gregarines infesting earthworms from Senchal of Darjeeling and Ranaghat of Nadia districts of West Bengal, India revealed the occurrence of two new species of Monocystis Stein, 1848. Monocystis darjeelingensis sp.n. was found in the coelomic fluid of the earthworm Amynthus robusta Perrier, 1892 from Senchal, Darjeeling, and M. ranaghatensis sp.n. in the seminal vesicles of the earthworm Eutyphoeus valtoni (Michaelsen) from Ranaghat. Trophozoites of M. darjeelingensis sp.n. are cylindroid in shape: 210.0-273.0 (231.0 ± 2.0) × 84.0-140.0 (98.0 ± 1.8) μm; spherical gametocyst: 147.0-163.0 (156.0 ± 0.4) μm; navicular oocyst: 15.4-18.0 (17.0 ± 1.0) × 8.0-9.0 (8.2 ± 0.5) μm. Trophozoites of M. ranaghatensis sp.n. are napiform, having a nearly spheroid to ellipsoid or ovoid body, 119.0-167.0 (124.0 ± 11.0) × 57.0-84.0 (62.0 ± 1.9) μm with a prominent tail like structure at the posterior end and ellipsoidal nucleus, 9.022.0 (12.0 ± 0.4) × 9.0-13.0 (10.0 ± 1.5) μm. Gametocysts are egg-shaped, measuring 95.0-124.0 (105.0 ± 0.9) μm. Oocysts are biconical, measuring 7.6-10.1 ( 9.3 ± 1.1) × 4.1-5.6 (4.5 ± 1.3) μm.

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.
