A New Species

A new species of Trogia (Marasmiaceae, Basidiomycota) is described from West Bengal, India. Analysis of the molecular sequence (nuclear ribosomal internal transcribed spacer region) data suggests that T. benghalesis is phylogenetically distinct from its closely related species.

AbstractA new species of Bipaliid land planarian, Bipalium bengalensis is described from Suri, West Bengal, India. The species is jet black in colour without any band or line but with a thin indistinct mid-dorsal groove. Semilunar head margin is pinkish in live condition with numerous eyes on its margin. Body length (BL) ranged from 19.00 to 45.00mm and width varied from 9.59 to 13.16% BL. Position of mouth and gonopore from anterior end ranged from 51.47 to 60.00% BL and 67.40 to 75.00 % BL respectively. Comparisons were made with its Indian as well as Bengal congeners.Salient features, distribution and biometric data of all the 29 species of Indian Bipaliid land planarians are revised thoroughly. Genus controversy in Bipaliid taxonomy is critically discussed and a proposal of only two genera Bipalium and Humbertium is suggested.

A New Species

Surveys of the endoparasitic acephaline gregarines in West Bengal revealed a new species of the genus Monocystis Stein, 1848, that resides in the seminal vesicle of the earthworm Lampito mauritii. Monocystis clubae sp. nov. is characterized by a club-shaped gamont having a taillike structure at the posterior end and measures 104.0–179.0 (160.0±24.5) µm x 62.5–71.0 (64.0±6.5) µm. Shape of the gametocysts are rounded to ovoid and measures 88.0–107.0 (104.0±1.3) µm x 86.0–102.0 µm (96.0±1.9) µm in diameter. Oocysts are navicular in shape and measures 9.6–11.0 (10.4± 0.3) µm x 7.3–8.0 (7.6±0.2) µm.

A New Species

Lactarius brunneocinnamomeus found in Shorea robusta (‎Dipterocarpaceae) dominated forest, is proposed as a new species. The species belongs to L. subg. Russularia, sect. Russularia. It is easily recognized by a light brown to orange brown pileus with concentric zones, milky white latex and a palisade to trichopalisade as a pileipellis. Its phylogenetic position inside the genus is based on the nuclear internal transcribed spacer (ITS) region. A complete description, drawings and photographs of the new species are provided. The new species is compared with morphologically similar and phylogenetically allied 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.

Surveys of acephaline gregarines infesting earthworms from Kalyani of Nadia districts of West Bengal, India revealed the occurrence of a new species of Monocystis Stein, 1848. Monocystis levinei sp. nov., found in the coelomic fluid of the earthworm. Trophozoites of M. levinei sp. nov. are elongated in shape, 145.0–175.0 (163.0±1.5) µm x 18.0–43.0 (29.0±1.1) µm with a prominent taillike protrusion at the posterior end, measuring 7.0–10.0 (7.9±7.9) µm x 1.5–3.1 (1.8±2.1) µm and rounded nucleus, measuring 14.2–26.3 (22.3±7.3) µm x 18.4–30.5 (26.4±2.6) µm. Gametocysts are ovoid in shape ranging from 130.0–163.0 (152.0± 0.4) µm, whereas oocysts are navicular in shape, ranging in size from 8.9–12.0 (10.4±1.0) µm x 5.2–7.3 (6.9±0.5) µm.

A New Species

Cestrus itatiensis sp. nov., from the Brazilian Atlantic Forest, is described and illustrated. This is the southernmost record for the genus and the first record in Brazil. The new species is characterized by having the body reddish brown; a narrow yellow stripe along eye margin on supra-clypeal area, reaching briefly the supra-antennal area; transverse carina of propodeum complete and stout; postpetiole and T2–8 progressively dark brown towards apical margin in a somewhat triangular pattern; and apex of dorsal valve of ovipositor with nine distinct teeth. Extensive sampling suggest this is a rare species.
