Diagnosis

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 present, but reduced ( Fig. 24A, C View Fig ); retrolateral surface of cheliceral claw without row of setae; first (dorsal) tooth bifid, dorsal cusp smaller than ventral cusp ( Fig. 10C–D View Fig ); claw with four denticles ( Fig. 10C–D View Fig ); tibia of leg I with 21 articles, tarsus I with 39 articles; leg IV basitibia with three pseudo-articles; trichobothrium bc situated closer to bf than to sbf; sc and sf series each with 5 trichobothria.

Charinus miskito sp. nov. resembles C. bruneti , as both possess median eyes, tibia of leg I consists of 21 or 22 articles, and tarsus I consists of 39 articles. However, the median eyes are reduced in C. miskito sp. nov. and well developed in C. bruneti .

Etymology

A noun in apposition referring to the Miskito, a Native American tribe in Central America.

Description

CARAPACE.Anterior margin rounded, with six anterior setae ( Fig. 24A View Fig ). Small granules densely scattered between ocular triads and among sulci. Median eyes and ocular tubercle present, but reduced ( Fig. 24A, C View Fig ); lateral eyes well developed, pale; small seta posterior to each lateral ocular triad; lateral ocular triad well separated from carapace margin.

STERNUM. Tritosternum projected anteriorly into large blunt tubercle, surpassing base of pedipalp coxae, with typical setation ( Fig. 24B View Fig ); medial platelet (tetrasternum) and third platelet (pentasternum) formed by two convex platelets, each with large setae anteriorly, and several smaller setae posteriorly ( Fig. 24B View Fig ); pentasternum smaller than medial platelet, each platelet with seta anteriorly and some setae posteriorly ( Fig. 24B View Fig ); pentasternum without anterior setae in membranous region and with four setae posteriorly.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Female genital operculum with posterior margin slightly convex, several setae along margin and surface ( Fig. 5E–F View Fig ); gonopods cushion-like with small rounded projection and sclerotized region on projection ( Fig. 5E–F View Fig ); small sclerotized region at base of gonopods (sclerotizations connected to each other) ( Fig. 5E–F View Fig ). Male gonopod with sclerotization at margin of fistula and lateral lobe 1; lateral lobe 2 fimbriate and short ( Fig. 25A–B, D View Fig ); lateral lobe 1 with acute apex ( Fig. 25F View Fig ); processus internus short and with median projection ( Fig. 25E View Fig ); dorsal lobe covered with denticulate projections ( Fig. 25C, F View Fig ).

CHELICERAE. Chelicera with small, flat tooth in retrolateral row of basal segment, opposite to bifid tooth ( Fig. 10D View Fig ); bifid tooth with dorsal cusp smaller than ventral cusp; prolateral surface of cheliceral basal segment with transverse row of around ten small setae, ventrally to dorsally; retrolateral surface of claw without row of setae; claw with four teeth ( Fig. 10C–D View Fig ).

PEDIPALPS. Coxal dorsal carina with two or three setae on anterior border and without seta encircled by round carina. Femur with two distinct setiferous tubercles proximal to spine 1 ( Fig. 24E View Fig ); primary series with three dorsal spines and three ventral spines; femur with one setiferous turbercle between ventral spine 1 and proximal margin. Patella with three dorsal spines and one long setiferous tubercle, about one-third length of spine I, between spine I and distal margin of segment ( Fig. 24E View Fig ); several long setae between ventral spines. Tibia with ventral spine in distal half of article and prominent setiferous tubercle close to base ( Fig. 24F View Fig ); long seta between spine and distal margin. Tarsus with two dorsal spines, distal spine two thirds length of article and proximal spine one-third length of distal spine ( Fig. 24D View Fig ). Ventral row of cleaning organ with 28–32 setae.

LEGS. Tibia of leg I with 21 articles; tarsus I with 39 articles; tarsal organ situated near claw ( Fig. 26A, C–D View Fig ); rod sensilla with four setae in shallow groove ( Fig. 26B, E View Fig ). Leg IV basitibia with three pseudoarticles, without sclerotized, denticulate projection at distal apex of articles; trichobothrium bt situated in proximal third; leg IV distitibia with trichobothrium bc situated closer to bf than to sbf; sc and sf series each with five trichobothria.

Distribution

Known only from the type locality. Providencia is a volcanic island, part of the territory of Colombia, but biogeographically part of the Caribbean and Central America, its fauna more closely related to Central America and the Lesser Antilles than to the Greater Antilles ( Morrone 2006).

Natural history

Epigean, found under stones.
