A new species of nemacheilid loach, Aborichthys uniobarensis, is described from the Senkhi stream, upper Brahmaputra basin in Arunachal Pradesh, northeastern India. Aborichthys uniobarensis is distinguished from all congeners by the presence of 6–14 fused oblique bars along the dorso-lateral margin of the body, 21–28 oblique bars along the flank, vent closer to the snout tip than to the caudal fin base and caudal fin oval shaped with upper half more extended than lower.

Hemiodus jatuarana, a new species of the Hemiodontidae from Oriximin , rio Trombetas, Amazon Basin, Brazil, is described. The new species can be readily distinguished from its congeners by the presence of a horizontally elongated dark spot on the caudal peduncle, and by the absence of any other dark pigmentation pattern on the body. Hemiodus jatuarana is readily separated from H. immaculatus, another species without dark pigmentation on the body, by having 25 27 epibranchial and 36 37 ceratobranchial gill rakers on the first branchial arch, and caudal-fin lobes without longitudinal stripes, vs. 14 16 and 21 25 gill rakers, and a conspicuous longitudinal stripe on each caudal-fin lobe in H. immaculatus. The new species is only known from its type-locality, where it cooccurs with H. immaculatus.

A new species of the genus Moenkhausia is described from the middle portions of the Rio Tocantins and tentatively from the Rio Apure in Venezuela, Rio Orinoco drainage. It is diagnosed by the presence of a dark spot in the half proximal length of the upper caudal-fin lobe, and by the presence of a large, irregularly shaped humeral spot located above the sixth to ninth perforated lateral line scale which is more posteriorly positioned along the body side in relation to other members of the genus. The distribution pattern of the new species is discussed.

A New Species

Exostoma kottelati, new species, is described from the Ranga River, Brahmaputra basin, in Arunachal Pradesh state, northeastern India. It differs from congeners in the Brahmaputra River basin in having a longer adipose-fin base (33.4–36.0 % SL vs. 23.4–32.9), a greater (except E. mangdechhuensis) pre-pelvic length (45.6–47.3 % SL vs. 39.3–44.6) and a greater pre-anal length (73.9–76.5 % SL vs. 62.2–70.1). It further differs from all known congeners by the following unique combination characters: the adipose fin is distinctly separated from the dorsal procurrent caudal-fin rays, pre-dorsal length 38.9–41.7% SL, adipose-fin base length 33.4–36 % SL, caudal peduncle length 18.7–21.1 % SL, caudal peduncle depth 8.8–9.5 % SL, and body depth at anus 12.5–13.5 % SL. This is the fifth species of Exostoma known from the Brahmaputra River basin.

A New Species

In 2015, during a floristic expedition in northeastern India, a population of an unusual Zingiber Miller (1754: 525) was found near Durga Mandir, between Bomdilla and Balukpong, in West Kameng District, Arunachal Pradesh. At a first glance the species clearly belongs to section Cryptanthium Horaninow (1862: 27) in having a procumbent peduncle. Detailed studies revealed that it does not match any of the known species of Indian Zingiber, hence it is described here as new. Plants of this population are morphologically similar to Z. bipinianum Roy et al. (2015: 298) and Z. mizoramensis Kumar et al. (2015: 81), but detailed studies of the types and protologues confirm the novelty of this species. We also consulted relevant literature discussing Indian Zingiberaceae, which further confirms that this is a new species (e.g. Bai et al. 2015, Baker 1892, Leong-Škorničková et al. 2015, Kishor & Leong-Škorničková 2013, Kumar et al. 2013, 2015, Mood & Theilade 2002, Roscoe 1828, Sabu 2003, 2006, Sabu et al. 2009, 2013b, Talukdar et al. 2015, Thongam & Konsam 2014, Thongam et al. 2013, Triboun et al. 2014, Tripathi & Singh 2006, Wu & Larsen 2000).

A New Species

A new species of green pit vipers of the genus Trimeresurus Lacépède, 1804 is described from the lowlands of western Arunachal Pradesh state of India. The new species, Trimeresurus salazar, is a member of the subgenus Trimeresurus, a relationship deduced contingent on two mitochondrial genes, 16S and ND4, and recovered as sister to Trimeresurus septentrionalis Kramer, 1977. The new species differs from the latter in bearing an orange to reddish stripe running from the lower border of the eye to the posterior part of the head in males, higher number of pterygoid and dentary teeth, and a short, bilobed hemipenis. Description of the new species and T. arunachalensis Captain, Deepak, Pandit, Bhatt & Athreya, 2019 from northeastern India in a span of less than one year highlights the need for dedicated surveys to document biodiversity across northeastern India.
