Diagnosis. Males of Acanthoctenus remotus ( Fig. 34 A–B; Polotow & Brescovit 2012: fig. 1a–b) resemble those of A. lamarrei sp. nov. ( Figs 42 D–E, 43A–B) by the median apophysis massive, the apex at least five times wider than the base, and the palpal tibia elongated, at least 2.5 times longer than wide. It can be distinguished by the embolus elongated, the base slightly swollen and starting at 9 o’clock, and the apex ending at 2 o’clock, and the RTA reduced, wider than long. A. lamarrei sp. nov. presents a shorter embolus, the apex ending at 12 o’clock, the base swollen at least four times the apex width, and RTA elongated, longer than wide. Females of Acanthoctenus remotus ( Fig. 34 C–D; Polotow & Brescovit 2012: 41, fig. 1d–c) resemble those of A. dumicola stat. res. ( Figs 19 A–B, 20D, 21A–B) by the atrium with two strongly sclerotized anterior borders and the lateral sectors anterior border forming a 30° angle with the median sector longitudinal axis. It can be distinguished by the median sector elongated, more than two times longer than wide, and the atrium broader. A. dumicola stat. res. presents a reduced media sector, 1.5 times longer than wide, and a narrowed atrium.

Description. See Polotow & Brescovit (2012).

Distribution. Jamaica ( Fig. 10A ).
