https://www.selleckchem.com/products/ttk21.html Ithocritus ruber (Hope, 1839), the type species of the genus Ithocritus Lacordaire, 1872 is reinvestigated, and a partially sympatric species, Ithocritus similis Bi Lin, sp. nov. (, Xiāng sì duǎn bǐng tiān niú), is described. The genus Falsimalmus Breuning, 1956 is newly recorded from China, based on the discovery of Falsimalmus niger Breuning, 1956 from Yunnan. New localities, illustrations of habitus, endophallic structure and major diagnostic features for all involved taxa are provided.The morphologies of the three freshwater stentorid ciliates in Korea, Stentor coeruleus (Pallas, 1766); Stentor muelleri Ehrenberg, 1831, and Stentor tartari Murthy Bai, 1974, were investigated based on live observations and protargol impregnation. The Korean population of S. tartari exhibits the following characteristics body size 200-355 × 85-135 µm in vivo, 62-106 somatic kineties, 8-13 peristomial kineties, 110-180 adoral membranelles, mostly two macronuclear nodules and 5-18 micronuclei, reddish and colorless cortical granules and the presence of symbiotic algae. We identified S. tartari based on unique characteristics compared to close congeners. Korean populations of S. coeruleus and S. muelleri are congruent with previously described populations in most aspects of their morphologies. Here, for the first time, we report molecular gene sequence information for S. tartari. Small subunit (SSU) rRNA gene sequence-based phylogeny indicates that S. tartari, which has multiple macronuclei, forms a monophyletic group with other Stentor species having a single macronucleus. Our findings based on morphology and SSU rRNA gene sequence information corroborate the hypothesis that the elongated macronucleus evolved from the compact single or multi macronucleus state.The dobsonfly genus Protohermes van der Weele, 1907 is recorded from Pakistan for the first time. Two species, i.e. Protohermes motuoensis Liu Yang, 2006 and Protohermes walkeri
