New records. Colombia: Sucre: Toluviejo: Bobo Stream, station 6 (09°33′46″ N, 075°24′51″ W), Wendy Molina-J., 28.II.2015 (WMJ 030). Colombia: Sucre: Toluviejo: Camarón Stream (09°32′32″ N, 075°24′33″ W), Claudia Moreno-R., 11.II.2017 (CMR 115).

Identification. Males examined were easily identified as L. aduncus based on the shape of abdominal segment VIII, which has a small, downward curving, apical projection on the ventral surface ( Fig. 9). Females are more difficult to identify but could be recognized by the antennomere I longer than the head width including the eyes, dorsal portion of the mesopleura dark with a transversal light stripe in the middle, last abdominal laterotergite clearly projected posteriorly ( Fig. 10), and posterior margin of abdominal sternite VII sharply projected in the middle ( Nieser 1970).

Distribution in the Colombian Caribbean region. Cesar ( Aristizábal-García 2017), Córdoba (Aristizábal- García 2002), Magdalena ( Molano-Rendón et al. 2008, Aristizábal-García 2017), Sucre ( Aristizábal-García 2017, this work).
