24. Cryptocanthon escobari Cook View in CoL sp.nov.

( Figs. 130–134)

Material Examined. Two specimens (1 male, 1 female).

Type Material. Holotype: ‘‘ COLOMBIA: Boyacá / Cusiana Comijoque / 58269050N, 728419300W / 2,000 m Bosque ExH / F. Escobar Junio / 970 ( CMNC) male . Paratypes (1): same data as holotype ( CMNC) female .

Etymology. The epithet ‘‘escobari’’ is a patronym in recognition of the collecting of Federico Escobar, Instituto Humboldt, Colombia.

Diagnosis. This species is distinguished by the following combination of characters: vertical surface of clypeus foveate; pronotal hypomeron not carinate; inflexed portion of elytron lacking basal fovea; metathoracic wings greatly reduced; pygidium evenly convex; paramere apices truncate, with fringe of setae ( Fig. 133).

Description. Holotype. Male. Total length 4.2 mm; greatest width 2.7 mm. Head. Clypeus not strongly produced anteriorly ( Fig. 131). Clypeal teeth moderately developed, widely separated, moderately reflexed. Clypeal emargination evenly rounded; vertical surface broadly V-shaped, with small, round, deep fovea. Apical margin of clypeus lateral to teeth convexly arcuate. Disc of clypeus concave, with moderately small punctures separated by about one diameter. Clypeogenal suture faintly indicated. Gena not produced, with slight angle at junction with anterior margin of clypeus; punctation similar to that of clypeus. Vertex with small punctures separated by less than one diameter. Pronotum. Convex medially, laterally explanate, with shallow depressions laterally in posterior half. Anterior angles approximately rightangled. Sides anterior to lateral angles slightly concave; straight posterior to lateral angles. Posterior angles obtuse, not incised. Pronotum densely punctate; punctures small and deep, except posterolaterally where they are shallow and slightly larger; setae inconspicuous, very fine, pale, recumbent. Pronotal hypomeron convex, with small, shallow punctures; longitudinal carina absent. Elytra. Transversely and longitudinally moderately, evenly convex; lateral carinae not elevated. Each elytron dorsally with seven striae, each stria indicated by two wavy lines. Elytral intervals slightly convex; each interval with row of fine setose punctures on each side adjacent to striae; setae pale, strongly arched. Inflexed portion of elytron moderately broad, evenly narrowed apically, with scattered, very fine punctures; irregular transverse wrinkles in apical third; basal fovea absent; one stria (eight or nine) vaguely indicated in basal half, ten complete along margin of epipleuron. Epipleuron with row of punctures along inner margin.

Wings. Metathoracic wings greatly reduced. Venter. Prosternum with medium-sized shallow, annulate punctures. Mesosternum with shallow, annulate punctures; punctures small and scattered medially, medium-sized and more dense laterally. Meso-metasternal suture broadly angulate medially. Metasternum flat medially; disc finely punctate in anterior two-thirds, with medium-sized shallow punctures in posterior third; laterally, punctures large, dense, annulate. Legs. Profemur strongly punctate ventrally. Protibia ( Fig. 130) with medial expansion in apical half before notch; subapical notch present. Mesofemur and metafemur with small, elongate punctures ventrally. Metatrochanter unmodified. Metatibia angulate, inner margin not crenulate and without subapical lobe or tooth. Abdomen. Apical sternite evenly convex, with small punctures medially and medium-sized, shallow punctures laterally. Pygidium evenly convex, with irregularly spaced, shallow punctures; base without median fovea. Male genitalia. Parameres ( Figs. 132–133) with apices truncate, with fringe of pale setae.

Variation. Female: total length 4.3 mm; greatest width 2.7 mm; clypeal teeth more strongly developed; protibia unmodified.

Bionomics. This species has been collected during June in human dung traps in forest, at 2,000 m elevation.

Geographic Distribution ( Fig. 134). This species occurs in the Cordillera Oriental of Colombia, in the division of Boyaca´.
