EASTER ISLAND - Oncopagurus sp. A. - Zhadan, 1997: 67, fig. 9 (Seamounts Sala y Gòmez and Nazca ridge, r/v Pr. Stockman, 25°05.7'-25°59.8'S, 99°27.7'-100°40.0'W; 330-750 m; "This species closely resembles O. tuamotu (Lemaitre, 1994) and O. cidaris Lemaitre, 1996 and is in fact something intermediate between these species")

Comment(s) on data
Lemaitre (2014: 295, Raffles Bulletin) - Zhadan (1997: 69) stated that differences observed in the few specimens he reported as Oncopagurus sp., did “not allow to describe this form as a new species”. Although Zhadan indicated that his specimens were intermediate between O. tuamotu and O. cidaris, it is not possible to ascertain which taxon the specimens could represent based on his description and figures. Regrettably, Zhadan’s material has not been available for examination, and he did not illustrate several important features, such as shield and cephalic appendages, left cheliped, ambulatory legs, uropods, and telson. Furthermore, a number of Oncopagurus species have been described since Zhadan’s study that could possibly be conspecific with his specimens, in addition to the new species described in the present study
