Diagnosis. Body general coloration brown with dark brown marks. Mirror divided in its medium length, vertex and pronotum with abundant setae. Ectoparamere elongated and dorsal-ventrally flattened; epiphallus divided in the distal portion; endoparameron distally dilated, surrounding the virga ( Fig. 21 A).

Description. Male. Body general coloration light brown with dark brown marks; rostrum, mouthparts and genae whitish brown ( Fig. 21 C). Head ovoid and wider than long, vertex dark brown. Rostrum with a brown stripe at each side from the eye margin to the superior edge of the clypeus. Pronotum tumescent with abundant setae, frontal edge of the lateral lobes with a whitish yellow transversal stripe ( Fig. 21 B). Fore-, meso- femora and tibiae laterally flattened, and with several dark brown marks. Foretibiae bears tympanal organs at each side. Hind-tibiae with four dorsal spines on each margin, additionally armed with three spines in the distal portion of both the external and internal margins. Tegmina elongated with the posterior-distal portion enlarged; mirror divided in its middle length, lower margin of the mirror with a brown stripe; mirror surrounding cells with brown marks. Tenth tergite without modification; cerci cylindrical and elongated; subgenital plate ovoid. Phallic complex ( Fig. 21 A): Ectoparamere moderately elongated and scapula shaped; epiphallus moderately elongated, plate shaped and distally forked forming a “U” shaped notch; virga reduced and triangular shaped; endoparamere shaped like parallel rods, more dilated in the epiphallus area; rami arcuate and distally detached.

Female. Unknown.

Etymology: This new species is named after Kwaiker , another name for the same Awa community (indigenous community that inhabits the area of the Ñambí River Natural Reserve).

Comments. This constitutes the first formal record of the genus Antillicharis for South America. Antillicharis is a very specious genus (70 described species) distributed mainly in Caribbean Islands, except for a species described from Guatemala ( Eades et al., 2016). The new species herein described is similar to A. oriobates , but the latest can be recognized because of the lack of marks in the tegmina and the severely tomentose pronotum; although the ectoparamere structure is similar in both species, Antillicharis kwaiker n. sp. can be recognized because of the endoparamere dilated in the epiphallus area and the absence of an accessory fold in the epiphallic apodeme, additionally, the epiphallus covers the ventral-superior portion of the phallic complex; and in A. oriobates the epiphallus is belt shaped and covers ventrally the base of the ectoparamere.
