Description. Female ( Figs 125–128 ). Integument mostly dark brown, almost black; antennomere III dark brown dorsally and laterally, dark reddish brown ventrally except dark brown distal area; antennomere IV dark reddish brown on basal 2/3, dark brown on distal third; antennomeres V–XI reddish brown basally, dark brown on remaining surface; mouth parts dark reddish brown except palpomeres dark brown distally.

Head. Frons and vertex moderately coarsely, abundantly punctate except impunctate area between posterior edge of eyes and prothorax; with ochraceous pubescence partially obscuring integument (punctures distinctly exposed), with long, erect, moderately abundant yellowish setae interspersed, longer, darker close to lower eye lobes (erect setae absent on area close to prothorax). Area behind eyes impunctate; with ochraceous pubescence obscuring integument behind upper eye lobes, and close to lower eye lobes; remaining surface behind lower eye lobes glabrous; with a few long, erect yellowish setae behind upper eye lobes, and both short and long, erect yellowish setae behind lower eye lobes. Antennal tubercles with punctures as on frons basally, smooth toward apex; with ochraceous pubescence partially obscuring integument, with a few long, erect brownish setae interspersed. Median groove distinct from middle of frons to prothoracic margin. Genae with ochraceous pubescence not obscuring integument, except smooth distal area, with a few long, erect yellowish setae interspersed. Gulamentum smooth, glabrous except on depressed area close to mentum with ochraceous pubescence not obscuring integument, with long, erect yellowish and brownish setae interspersed. Labrum moderately coarsely, sparsely punctate on distal region of coplanar area with anteclypeus; with ochraceous pubescence not obscuring integument, with long, erect yellow setae interspersed, mostly on distal inclined area. Distance between upper eye lobes 0.47 times length of scape (1.6 times width of one lobe); in frontal view, distance between lower eye lobes 0.92 times length of scape. Antennae 1.44 times elytral length, reaching elytral apex at basal quarter of antennomere XI. Scape distinctly widened internally from base to about middle; with ochraceous pubescence not obscuring integument, with long, erect yellow setae interspersed ventrally on distal half; antennomeres III–IV with ochraceous pubescence interspersed with grayish white setae on basal 2/3; antennomeres V–X with grayish white pubescence on basal light area, ochraceous on remaining surface; pedicel and antennomeres III–XI with long, erect setae ventrally, yellowish on antennomere III and most of IV, brownish on remaining antennomeres, sparser toward XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.91; pedicel = 0.19; IV = 1.28; V = 0.95; VI = 0.87; VII = 0.82; VIII = 0.76; IX = 0.76; X = 0.70; XI = 0.74.

Thorax. Prothorax, maximum width 1.4 times wider than long (including lateral tubercles); lateral tubercles large, placed at middle, with apex acute. Pronotum with 3 slightly distinct gibbosities, one more distinct, subelliptical, placed centrally on basal half, one subcircular, placed on each side of distal half; coarsely, moderately abundantly punctate except smooth central gibbosity; with ochraceous pubescence partially obscuring integument, with moderately long, erect yellowish and brownish setae interspersed. Sides of prothorax coarsely, moderately abundantly punctate centrally close to pronotum, sparsely, shallowly punctate toward prosternum, smooth basally and distally; with ochraceous pubescence partially obscuring integument, especially centrally. Prosternum moderately finely, sparsely punctate on basal half, nearly smooth on distal half; with yellowish white pubescence not obscuring integument, with long, erect yellowish setae interspersed. Prosternal process longitudinally, widely sulcate centrally; rugose-punctate; with yellowish white pubescence, distinctly bristly toward apex. Ventral side of meso- and metathorax with yellowish white pubescence not obscuring integument, sparser on central area of mesoventrite. Scutellum with ochraceous pubescence partially obscuring integument. Elytra. Coarsely, abundantly punctate on basal third, gradually finer, sparser toward apex; with ochraceous pubescence partially obscuring integument, with long, erect setae interspersed, browner on its base, gradually yellowish toward apex; apices slightly obliquely truncate. Legs. Femora with light ochraceous pubescence partially obscuring integument.

Abdomen. Ventrites with yellowish white pubescence not obscuring integument, with long, erect yellowish setae interspersed; distal area of ventrite V depressed; apex of ventrite V truncate.

Male ( Figs 16–18 , 129 ). It differs from the female by having longer antennae (1.6 times elytral length, reaching elytral apex at middle of antennomere IX).

Dimensions (mm), female. Total length, 9.67–8.59; prothoracic length, 1.67–1.57; basal prothoracic width, 1.82–1.67; distal prothoracic width, 1.67–1.50; maximum prothoracic width (between apices of lateral tubercles), 2.34–2.07; humeral width, 2.83–2.56; elytral length, 6.84–6.03.

Material examined. COSTA RICA, Puntarenas: Monteverde ( Campbell’s Woods ; 10º19’N / 84º49’W), 2 females, 29.V.1992, S. Lingafelter col. ( SWLC, MZSP) . PANAMA, Chiriqui: Volcan Baru , 1 male, 11.VII.1981, B. K. Dozier col. ( FSCA) .

Remarks. Estoloides prolongata is similar to E. parva Breuning, 1940 , by the antennomere III slightly longer than scape in female, but differs as follows: pronotal punctures fine ( Fig. 125 ); elytra 4 times prothoracic length; elytral punctures fine and more abundant ( Fig. 125 ). In E. parva ( Figs 130, 132 ), the pronotal punctures are coarse, elytra slightly longer than 3 times prothoracic length, elytral punctures coarse and sparse. The male examined ( Fig.

129) has the prothorax narrower than the syntype male. However, there is no other character allowing separation of these two specimens, collected in the same locality. We are adding Costa Rica as a new country record.
