Revision of the genus Lolliguncula Steenstrup, 1881 (Cephalopoda: Loliginidae) off the Pacific Coast of South America

In the present paper the species from the genus Lolliguncula Steentrup, 1881 (Cephalopoda: Loliginidae) in Southeastern Pacific Ocean are reviewed. The presence of Lolliguncula (Lolliguncula) panamensis Berry, 1911, Lolliguncula (Loliolopsis) diomedeae Hoyle, 1911 and Lolliguncula (Lolliguncula) argus Brakoniecki and Roper, 1985 are confirmed from Mexican waters to Peru and the species Lolliguncula (Lolliguncula) argus collected during a cruise of the R/V Anton Bruun from 1966 off the coast of South America is recorded for the first time in Peruvian waters. A key to identification of Pacific species is given. We report a diagnostic feature with taxonomic remarks of these species. Updated information on the distribution, biology, and fisheries of each species also is discussed.
