Notes on two shallow water isopods (Crustacea: Peracarida: Isopoda: Idoteidae) from Kino Bay, Gulf of California, Mexico

Abstract

Two species of isopods of the family Idoteidae were collected in the same sample, among sea grasses, in the northern Gulf of California, Mexico. Th e fi rst species, Synidotea harfordi Benedict, 1897, was more abundant (46 specimens) than the second species, Eusymmerus antennatus Richardson, 1899 (eight specimens). Synidotea harfordi has previously been considered uncommon in the Gulf of California, and more like a component of warmtemperate to colder-water fauna. Th e male of E. antennatus has not been illustrated but SEM photographs are provided and show angular margins of the fi rst three pereonites and a sharply bent lateral margin of the telson. Females also have angular fi rst pereonites. All previous illustrations show rounded pereonites margins. Buccal appendages of E. antennatus are illustrated and compared with previous descriptions.

Checklist and new records of Lophogastrida (Malacostraca, Peracarida) in Chilean waters

“…Some of the most complete works dealing with the eastern Pacific lophogastrids are those by Tattersall (1951) and Banner (1954), who studied the material from the "Americas" included in the collections of the Smithsonian Institution, Washington D.C. Additional records of species, or new material of lophogastrids, were also reported by Austin (1985), Brusca and Hendrickx (2005), Ibarra and Hendrickx (2008), Hendrickx (2019), Hendrickx andLópez (2019), andHuber et al (2019). A complete checklist of lophogastrids occurring in the Mexican Pacific was proposed by Hernández-Payán and Hendrickx (2020) who reported eight species from this area.…”
