Anticyphon santanderensis sp. nov.

( Figs 1 H, 13)

Type material. Holotype, male (NHMB): “Bucaramanga Nord \ Santandar 3200 m \ Columbien \ XI.1960 G. Frey”

Diagnosis. The second largest species of the genus, pronotal disc with normal, not granulate punctures. Resembling A. davidsoni sp. nov. in size and pronotal punctation. It can be identified on the basis of male genitalia: trigonium is distinctly shorter than parameroids (almost as long as parameroids in A. davidsoni sp. nov.).

Description. Male. Body oval, moderately large, slightly flattened, clothed with brownish procumbent setae. Colouration of dorsum dark brown, antennae and legs dark brown. Head small, 1.7× wider than interocular space, covered with subtle granulate punctures; eyes relatively big, protuberant; frons with two shallow depressions. Mandibles without denticles on inner margins. Antennae as in genus description. Pronotum small, transversely rectangular, sides slightly curved, widest at posterior angles, anterolateral angles broadly rounded, not produced; disc moderately convex. Punctation of pronotum subtly granulate on lateral portions, very subtle and sparse in central portion. Pronotum without distinct pits along basal margin. Each elytron with 3 well marked longitudinal carinae. Elytral punctation irregular, relatively sparse; punctures shallow, separated by ca. 1.0 diameter. Penis ( Fig. 13 A) large (L 1.93 mm, W 0.41 mm), parameroids long, diverging apically, pointed at apices; trigonium subtriangular, without lateral processes, 2× shorter than parameroids, pala slightly longer than parameroids, narrow, with membranous dorsal processes of penis; tegmen ( Fig. 13 B) large (L 1.32 mm, W 0.52 mm), with narrow, subtriangular parameres, pointed at apices; sternite VIII ( Fig. 13 C) small (L 0.27 mm, W 0.52 mm), widely V-shaped, with sparse setae in apical portions; sternite IX ( Fig. 13 D) relatively small (L 0.47 mm, W 0.53 mm), consisting of two subtriangular hemisternites, lightly sclerotized, with setose apical portion; tergite VIII ( Fig. 13 E) (L 0.97 mm, W 0.87 mm) with transversely rectangular apical plate, apical portion darker, covered with microsetae, apical margin with row of dense, short setae intermixed with sparse, longer ones, basal portion of apical plate with transverse rod, apodemes shorter than apical portion; tergite IX ( Fig. 13 F) (L 0.92 mm, W 0.53 mm) distinctly narrower than tergite VIII, central portion lightly sclerotized.

Female. Unknown.

Measurements and ratios. Male (n=1): TL 6.5 mm, PL 0.95 mm, PW 2.10 mm, EL 5.70 mm, EW 3.80 mm, TL/EW 1.7, PW/PL 2.2, EL/EW 1.5, EL/PL 6.0.

Distribution. Colombia, known only from the type locality ( Fig. 14 ).

Etymology. After Santander department in Colombia.
