DOI: 10.15560/16.2.265

Authors: Natsumi Hookabe, Hiroshi Kajihara

Abstract: A single specimen of a monostiliferous hoplonemertean, collected from a depth of 25 m in Akkeshi Bay, northern Japan, represents the first record of Gurjanovella littoralis Uschakov, 1926 from the Northwest Pacific. The species has been known only from the type locality, White Sea, Russia, although some planktonic larvae from Oregon, USA, and a juvenile from the Sea of Okhotsk have been identified as a member of the genus by molecular sequence data. Our specimen differs from a topotype from the White Sea by 2.9% of uncorrected p-distance and 3.0% of K2P in terms of partial 658-bp sequence of the mitochondrial cytochrome c oxidase subunit I (COI) gene. Our COI phylogenetic tree indicates that each of the larvae from Oregon and the Sea of Okhotsk belongs in Gurjanovella but represents a different species from G. littoralis.

First record of Carcinonemertes conanobrieni Simpson, Ambrosio & Baeza, 2017 (Nemertea, Carcinonemertidae), an egg predator of the Caribbean spiny lobster Panulirus argus (Latreille, 1804), on the Caribbean Coast of Colombia https://checklist.pensoft.net/article/21287/ Check List 14(2): 425-429

DOI: 10.15560/14.2.425

Authors: Jaime A. Gonzalez-Cueto, Sigmer Quiroga

Abstract: Carcinonemertes conanobrieni Simpson, Ambrosio & Baeza, 2017, an egg predator of the spiny lobster Panulirus argus (Latreille, 1804), is recorded for the first time in Colombian waters and the Caribbean. Worms were isolated from an egg mass of a lobster caught at the Gulf of Salamanca, Magdalena. Little is known about the distribution of this species and currently this record from the Caribbean Coast of Colombia is the only one outside of the Florida Keys, USA. The new record suggests that this parasite might be present in the entire Caribbean Sea.

First records of Hubrechtella ijimai (Nemertea, Hubrechtiiformes) from Korea and China https://checklist.pensoft.net/article/15044/ Check List 13(4): 107-111

DOI: 10.15560/13.4.107

Authors: Alexei V Chernyshev, Shi-Chun Sun, Neonila E Polyakova, Chun-Yang Shen

Abstract: Hubrechtella ijimai is reported for the first time from South Korea (East China Sea) and China (Yellow Sea), about 260 and 930 km from the nearest locality in Japan. Additional morphological data, confocal laser scanning microphotographs, and DNA data (COI sequences) are provided. This species possesses high intraspecific genetic COI p-distances for nemerteans (1.6–6.3%).
