«Material: One articulated complete specimen, one right valve, four left valve, and several fragments.
Description: Delicate, thin small–medium shell (Table 1), nearly equivalve and slightly inequilateral. Irregular rounded-oval outline, larger in height than in length (Table 1). The umbo protrudes slightly on the cardinal margin. Right valve oval in shape, slightly oblique and convex. External surface shows very fine striae (observable with the hand lens) and concentric growth lines. Small auricles with oblique margin and fine growth lines (Table 1). Cardinal margin straight. Inner surface of the valve smooth. Left valve similar to the right one, but with numerous thin, radial ribs. Remarks: The absence of either ornamentation or ribs in the outer surface of the valves is also observed in the species Amusium cristatum and Palliolum excisum. However, K. oblonga differs from A. cristatum since the former shows irregular rounded-oval morphology, is smaller and does not present ribs in the inner part of the valves. P. excisum is inequivalve, while K. oblonga is equivalve. Location and facies: In the studied deposits, Korobkovia oblonga is restricted to the silts and fine-grained calcarenites of the base of the Pliocene. This species occurs in Matagorda, Los Juanorros, Cueva de los Medina, and Los Ranchos sections.» JIMÉNEZ, A. P., J. AGUIRRE & P. RIVAS. 2009.
