Diagnosis

This species may be separated from other Caribbean and Central American Charinus by means of the following combination of characters: median eyes and ocular tubercle absent; cheliceral claw with four teeth, bifid tooth of basal cheliceral segment with dorsal and ventral cusps of equal size; leg tibia I with 23 articles; tarsus I with 41 articles; first article of tarsus 1.4–1.9 times as long as second article.

Etymology

Patronym honoring Dr James R. Reddel ( Miranda et al. 2016b).

Distribution

Known from the Footprint Cave and the Waterfall Cave (Actun Lubul Ha) in Belize.

Natural history

The species inhabits karst caves located in the valley of the Caves Branch River in central Belize. At the Footprint Cave, the most frequently encountered prey items were nymphs of Mayagryllus apterus Desutter-Grandcolas & Hubbell, 1993 ( Orthoptera : Gryllidae Laicharting, 1781 ) and Belicenochrus peckorum Armas & Víquez, 2010 ( Schizomida : Hubbardiidae Cook, 1899 ). The Waterfall Cave has an abundance of insects ( M. apterus , cockroaches) and other arthropods (isopods, spiders, soft ticks). An egg sac contained 4– 10 eggs measuring 1.5–1.64 mm in diameter and, at 25°C, egg development took ca 150 days. The hatching praenymphae measured 2.2–2.5 mm and spent 14 days on the mother’s back before molting into protonymphae measuring 2.8 mm in length.
