Diagnosis

Based on the description of Quintero (1983), this species may be separated from other Caribbean and Central American Charinus by means of the following combination of characters: median eyes and median ocular tubercle absent; lateral eyes small, but pigmented; bifid tooth of basal cheliceral segment with ventral cusp longer than dorsal cusp; cheliceral claw with four teeth; small tooth on retrolateral surface of basal cheliceral segment, opposite to bifid tooth; prolateral surface of cheliceral basal segment with transverse row of five setae; pedipalp femur with three dorsal spines and three ventral spines; pedipalp patella with three dorsal spines and two ventral spines; pedipalp tarsus with two dorsal spines; tibia of leg I with 21 articles, tarsus I with 39 articles; first article of tarsus approximately 4.5 times as long as second article; leg IV basitibia, trichobothrium bt situated in proximal third and bc situated equidistant between bf and sbf or slightly closer to bf; leg IV distitibia sc and sf series each with 5 trichobothria.

Etymology

Patronym honoring Dr Vasile Decu ( Quintero 1983) .

Type material

Holotype CUBA • ♂; Isla de la Juventud, Cueva del Abono ; [21°36′23.90″ N, 82°49′15.51″ W]; 11 Jun. 1969; ACC [ACC is now IES; L.F. de Armas, pers. com.; not deposited in collection according to Armas (2004, 2014)].

Paratypes CUBA • 1 ♀, 1 ♂, 2 ex. [dismembered]; Sierra de Casas ; [21°52′12″ N, 82°49′12″ W]; 23 Apr. 1973; MCZ [not examined] .

Measurements

See Table 1 .

Distribution

Known only from Isla de la Juventud, Cuba.

Natural history

This species is known to inhabit disturbed areas (e.g., Sierra Chiquita) and has also been collected inside caves (e.g., Cueva del Lago). It is sympatric with Paraphrynus viridiceps ( Pocock, 1893) and Phrynus pinero Armas & Ávila Calvo, 2001 .

Remarks

In the original description, Quintero (1983), counted four spines on the pedipalp patella, but included the long setiferous tubercle between spine I and the distal margin in the count. Additional differences between C. decu and other Caribbean species are discussed by Miranda et al. (2016b).
