Lipkebe holthuisi — Chace, 1969:263, 1972:25; Coelho & Ramos, 1972:146; Abele & Kim, 1986:14; Ramos-Porto & Coelho, 1998:331; Coelho et al., 2006:50.

Diagnosis. Rostrum nearly horizontal, laterally compressed in distal half, unarmed but carinate dorsally and ventrally, somewhat sinuous dorsally, convex ventrally, reaching as far as end of antennular peduncle. Antennular peduncle with acute stylocerite; strong distolateral spine of basal segment reaching second segment, anterior margin of basal segment produced between distolateral spine and lateral margin of second segment; proeminent spinelike process arising from near half of ventromesial surface of basal segment. Scaphocerite two times longer than broad, with distal tooth not overreaching the anterior margin of lamella. Carapace smooth, almost subcylindrical, with branchiostegal and hepatic spines. Mandible without palp. First pereopods overreaching antennal scale by chela, fingers unarmed and longer than palm. Second pereopods very unequal and dissimilar. Major cheliped overreaching scaphocerite by chela and carpus, dactylus with a large basal tooth closing into depression in fixed finger. Third to fifth pereopods with simple dactyli. Abdomen smooth, pleura of three anterior somites rounded and pleura of fourth and fifth somites broadly acuminate posteriorly. Telson with 2 pairs of dorsal spines and 3 pairs of spines on posterior margin.

Distribution. West Atlantic USA (Florida [Gulf of Mexico northeastern of Dry Tortugas]), Colombia (Santa Marta), Brazil (Pará, Rio Grande do Norte and Espírito Santo) ( Figure 5 ) ( Chace, 1969; Criales, 1984; Ramos- Porto, 1998; Coelho et al., 2006).
