The non-indigenous bryozoan Amathia verticillata (delle Chiaje, 1822) is recorded for the first time from the southern Mexican Pacific. The species was detected between 2014 and 2018 at three locations along the coast of Oaxaca, southwestern Mexico: Puerto Ángel Bay, Santa Cruz Bay, and La Blanca Island. A discussion on the introduction of the species to Oaxaca is also included.

Marine isopods, despite being a very diverse group, have been little studied in the Mexican South Pacific. After a revision of 171 specimens collected from Guerrero and Oaxaca, six new species, belonging to five genera, were discovered: Amakusanthura guerrerensis sp. nov., Cortezura caeca sp. nov., Mesanthura antenniformis sp. nov., M. estacahuitensis sp. nov., Skuphonura oaxaquensis sp. nov., and Tinggianthura mexicana sp. nov. In this work, the genera Amakusanthura Nunomura, 1977 and Tinggianthura Chew, Abdul-Rahim & Haji Ross, 2014, are recorded for the first time in the Tropical Eastern Pacific. Also, the distribution range of the genus Skuphonura Barnard, 1925 is increased from the west coast of South America to the southern Mexican Pacific, this being the first record of this genus in the Mexican Pacific. This study doubles the number of species recorded of Anthuridae from the Mexican Pacific, of six to 12 species.

Abstract It is recorded for the first time in the state of Rio Grande do Sul the occurrence of Scobina melanocephala (Lepeletier, 1823), Scobina thoracica (Jorgensen, 1913) and Scobina poeciloides (Ashmead, 1895), being this last the first record for Brazil. Scobina melanopyga (Klug, 1834) and Scobina torquata (Konow, 1903) were also found in the study. The analyzed material was collected utilizing Malaise traps in tobacco (Nicotiana tabacum L.) fields and is deposited at the Entomological Collection of Santa Cruz do Sul.

A New Species

The association of some species of polyclads of the suborder Acotylea with barnacles has been recorded worldwide. In contrast, no species of the suborder Cotylea has been recorded present in these crustaceans. The aim of this work is to describe the species of polyclads found in the empty barnacle shells on the coasts of Oaxaca, southern Mexican Pacific. Thirty polyclad specimens in the barnacles’ empty shells were collected, corresponding to two species. A new species of acotylean, Stylochus mistus sp. nov., was found in Paraconcavus pacificus; and the cotylean Prosthiostomum cf. parvicelis in Megabalanus peninsularis. Both species of polyclads are considered to use the shells of Megabalanus and Paraconcavus as an occasional shelter site; however, it is not ruled out that these species feed on these barnacles, as polyclads normally prey on the communities they inhabit. This work records for the first time the presence of a cotylean polyclad in barnacles, as well as the first record of the polyclad genera Stylochus and Prosthiostomum from the southern Mexican Pacific.

SummaryThe occurrence of the parasitic marine leech Stibarobdella moorei (Oka, 1910) (Hirudinea: Piscicolidae) along the northwest Mexican Pacific coast is described for the first time. This ectoparasite was collected from the skin of the Octopus bimaculatus (Verril, 1983) (Mollusca: Octopodidae). Stibarobdella loricata (Hardig, 1924) is synonymized with S. moorei as this species resembles other species of the genus based on tubercle patterns and the presence of papillae and a marginal fringe on the oral sucker. The present finding throws new light on the biodiversity and host preference of the ectoparasite and suggests a successful migration to unusual host. The coast of the Pacific Ocean, particularly in the Bay of Los Angeles, Baja California, Mexico is a new geographical distribution area for S. moorei, and O. bimaculatus is a new host reported for this leech. The morphology of this ectoparasite is briefly described.

Nodosilinea epilithica Perkerson et Casamatta is reported for the first time for Russia. The sample was isolated from a typical chestnut soil in the zone of dry steppes (Volgograd Region) and its identity was confirmed by morphological and molecular analyses. The specific feature of the studied strain is its ability to form nodules at normal (60–75 μmol photons ∙ m-2 ∙ sec-1) light. The number of nodules is supposed to be related to the age of a cyanobacterial culture.
