Kelleria reducta Gómez, 2006

Figures 18–20

Material examined. One adult female undissected, 1 dissected ( UARC 286M).

Remarks. The specimen from Colombia bears the diagnostic features of K. reducta previously reported from the adjacent Guajira department ( Suárez-Morales and Fuentes-Reinés 2015). Body cyclopiform, robust ( Fig. 18 ). Body length, excluding caudal setae: 910–994 μm (mean = 952 μm, n = 2). It can be easily separated from its congeners by its possession of 2 mediobasal teeth of mandibular blade which are remarkably larger than the others ( Fig. 19 ) and by a maxillipedal claw with 1 long and one reduced accompanying seta ( Fig. 20 ). These 2 distinctive characters are present in the specimen from Rodadero Bay, Magdalena.

Distribution. This species appears to have a widespread distribution in the area as it has been found from sieved sediment samples ( Gómez 2006), open water along the water column ( Suárez-Morales and Fuentes-Reinés 2015) and littoral zone (present study). Hitherto, K. reducta has been recorded from northwestern Mexico ( Gómez 2006) and Colombia ( Suárez-Morales and Fuentes-Reinés 2015); this is the first record in the Magdalena depart- ment, Colombia.
