Description

Holotype female: Integument mostly black; apex of palpomeres narrowly yellowish-brown; antennae dark brown, gradually lighter toward apex; tarsomeres V and claws dark reddish brown.

Head: Frons somewhat coarsely, abundantly punctate, with abundant minute punctures interspersed; with abundant yellowish-brown pubescence not obscuring integument, and short, decumbent, thick yellowish-white setae interspersed laterally. Area between antennal tubercles and upper eye lobes slightly depressed; sculpturing and pubescence as on frons, with a few short, decumbent, thick yellowish-white setae interspersed laterally. Remaining surface of vertex distinctly convex and elevated; with yellowish-brown pubescence not obscuring integument, sparser than on area between antennal tubercles and upper eye lobes. Area behind upper eye lobes with sculpturing and pubescence as on posterior region of vertex. Area behind lower eye lobes tumid, coarsely punctate close to eye; finely punctate close to prothorax; tumid area with abundant yellowish-brown pubescence not obscuring integument, and a few short, decumbent yellowish-white setae interspersed; area close to prothorax mostly glabrous. Genae shorter than lower eye lobe; finely punctate, except smooth apex; with yellowish-brown pubescence not obscuring integument, and short, decumbent, thick yellowish-white setae interspersed, except glabrous smooth area. Wide central area of postclypeus somewhat rugose-punctate; with yellowish-brown pubescence not obscuring integument, with a few short, suberect, slender whitish setae interspersed, one long, erect yellowish-brown seta on each side, and tuft of long, erect yellowish-brown setae laterally (shorter than previous setae). Sides of postclypeus smooth, glabrous. Labrum convex, coplanar with anteclypeus at posterior ⅔, inclined at anterior third; finely, sparsely punctate close to anteclypeus, coarsely, sparsely punctate close to inclined area, and coarsely punctate on inclined area, less so centrally; with short, decumbent, sparse whitish setae close to anteclypeus, long, erect yellowish setae close to inclined area, erect setae more abundant laterally, a few long, erect brownish setae on inclined area, and dense fringe of golden setae on anterior margin. Antennal tubercles finely, abundantly punctate; with abundant yellowish-brown pubescence not obscuring integument. Gulamentum smooth glabrous, except intermaxillary process finely punctate, with short, sparse yellowish-white setae. Distance between upper eye lobes 0.33 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.65 times distance between outer margins of eyes. Antennae 1.6 times elytral length, surpassing elytral apex at posterior third of antennomere XI. Scape minutely, abundantly punctate; with abundant yellowish-brown pubescence not obscuring integument, and short, decumbent,thick yellowish-white setae interspersed. Pedicel with yellowish-brown pubescence not obscuring integument, a few short, decumbent, slender whitish setae interspersed, and moderately long, erect yellowish-brown setae on apical ventral surface. Antennomeres III-XI with dense whitish pubescence basally, and abundant dark yellowish-brown pubescence not obscuring integument on remaining surface; with long, erect, sparse yellowish-brown setae ventrally. Antennal formula based on length of antennomere III: scape = 0.72; pedicel = 0.18; IV = 0.81; V = 0.50; VI = 0.44; VII = 0.40;VIII = 0.34; IX = 0.34; X = 0.31; XI = 0.37.

Thorax: Prothorax wider than long, sides uniformly rounded from anterolateral angles to posterior quarter, then subparallel-sided. Pronotum coarsely, somewhat abundantly punctate, punctures more abundant on central region; with eight gibbosities, one carina-shaped, longitudinal, located centrally, from anterior margin to about middle, gradually less elevated toward its posteri- or region, one subcircular, slightly elevated, located near anterior margin on each side of carina-shaped gibbosity, one elevated, subconical, located on each side just before middle, one somewhat irregular, slightly less elevated than previous ones, located centrally after middle, and one slightly distinct, oblique, elongate, located on each side of previous one; with somewhat abundant yellowish-brown pubescence not obscuring integument, slightly denser laterally, and small pale yellow pubescent macula centrally close to anterior and posterior margins; with short, decumbent, thick yellowish setae interspersed. Sides of prothorax coarsely, abundantly punctate; with yellowish-brown pubescence not obscuring integument, and a few short, decumbent, thick whitish setae interspersed. Prosternum abundantly, minutely punctate, with a few coarse punctures interspersed; with yellowish pubescence not obscuring integument. Prosternal process coarsely punctate; with bristly yellowish pubescence not obscuring integument; narrowest area 0.22 times procoxal width. Mesoventrite coarsely, sparsely punctate on wide central area, almost smooth laterally; with sparse yellowish-white pubescence on wide central area, and dense yellowish-brown pubescence laterally, except glabrous apex. Mesanepisternum coarsely, sparsely punctate; with abundant yellowish-brown pubescence not obscuring integument. Mesepimeron very finely, sparsely punctate; with abundant yellowish-brown pubescence not obscuring integument, except yellowish-white pubescence superiorly close to metanepisternum. Mesoventral process coarsely punctate, with yellowish-brown pubescence not obscuring integument; apical width 0.44 times mesocoxal width. Metanepisternum coarsely punctate; with abundant yellowish-brown pubescence not obscuring integument, pubescence more yellowish-white on some areas. Metaventrite with abundant yellowish-white pubescence not obscuring integument, pubescence partially yellowish-brown on some areas and sparser toward glabrous central area. Scutellum with dense yellow pubescence, except sparser pubescence on anterocentral region. Elytra: Coarsely, abundantly punctate on basal third, punctures gradually finer sparser toward apex; humerus bluntly, shortly projected; tubercles distinctly elevated,with blunt apex on anterior ⅔,smaller on posterior third; with abundant dark yellowish-brown pubescence not obscuring integument, and irregular tufts of dense light yellowish-brown pubescence interspersed, more abundant posteriorly;with a few short, decumbent, thick whitish setae interspersed. Legs: Femora with abundant brownish pubescence not obscuring integument, except glabrous posteroventral area of femoral club; with short, somewhat thick, decumbent white setae interspersed. Tibiae with yellowish-brown pubescence not obscuring integument, except bristly, dense yellowish-brown pubescence on posterior third of ventral surface, somewhat long, suberect yellowish-brown setae close to apex of dorsal surface on meso- and metatibiae, dense, erect yellowish-brown setae on dorsal sulcus of mesotibiae, and fringe of thick yellowish-brown setae on apex of all tibiae. Metatarsomere I slightly shorter than II-III together; dorsal surface of tarsomeres with whitish pubescence.

Abdomen: Ventrites with dark yellowish-brown pubescence not obscuring integument, pubescence denser laterally, and both, short and moderately long, decumbent whitish setae interspersed. Ventrite 5 widely, triangularly depressed on posterior half.

Dimensions (mm): Total length, 7.45; prothoracic length, 1.90; anterior prothoracic width, 1.80; posterior prothoracic width, 1.95; maximum prothoracic width, 2.25; humeral width, 2.75; elytral length, 4.75.

Type material: Holotype ♀ from HONDURAS, Lempira: 15 km SW Gracias , 21.III.1997, J. Prena leg. ( CASC, formerly LGBC).

Etymology: The specific epithet “ extensus ” refers to the wide distance between the antennal tubercles, which distinguished the new species from members of the genus Phrynidius .

Remarks: Based on the similar general appearance of Capaciphrynidius gen. nov. with Phrynidius , probably the males are also very similar to females.
