description: Anticyphon ecuadorensis sp. nov.
(Figs 1 B, 7)
Type material. Holotype, male (CMNH): “ ECUADOR: Azuay. Pass, \ 8 km NE Giron. 2600m \ 8 Nov 1987 J. Rawlins \ C. Young, R. Davidson \ Montane woodland”
Diagnosis. Body shape, size and granulate punctation of pronotal disc make this species similar to A. oyonensis sp. nov. and A. peruvianus sp. nov. Identifiable on the basis of male genitalia morphology: penis with subparallel parameroids, as long as median process of trigonium. Tegmen with apices of parameres curved ventrad.
Description. Male. Body oval, small, slightly flattened, clothed with yellowish procumbent setae. Colouration of dorsum yellowish brown, antennae and legs light brown. Head small, 1.1× wider than interocular space, covered with very granulate punctures; eyes relatively big, protuberant; frons with two shallow depressions. Antennae as in genus description. Mandibles without denticles on inner margins. Pronotum small, transversely rectangular, sides slightly curved, widest at posterior angles, anterolateral angles broadly rounded, not produced; disc moderately convex. Punctation of pronotum strong, granulate, both on lateral and central portions. Pronotum without distinct pits along basal margin. Each elytron with 3 subtly marked longitudinal carinae. Elytral punctation irregular, relatively sparse; punctures shallow, separated by ca. 1.0 diameter. Penis (Fig. 7 A) moderately large (L 1.38 mm, W 0.35 mm), parameroids long, straight, widened in apical portions, rounded at apices; trigonium with long median process and two short lateral lobes, median process almost as long as parameroids, pala much longer than parameroids, narrow; tegmen (Fig. 7 B) moderately large (L 1.13 mm, W 0.50 mm), with narrow, subtriangular parameres, hooked ventrad and pointed at apices; sternite VIII (Fig. 7 C) small (L 0.35 mm, W 0.40 mm), widely Vshaped, with sparse setae in apical portions; sternite IX (Fig. 7 D) relatively small (L 0.32 mm, W 0.35 mm), consisting of two suboval hemisternites, lightly sclerotized, with setose apical portion; tergite VIII (Fig. 7 E) (L 0.70 mm, W 0.58 mm) with transversely rectangular apical plate, apical portion covered with microsetae, apical margin with row of dense, short setae intermixed with sparse, longer ones, basal portion of apical plate darkened, apodemes shorter than apical portion; tergite IX (Fig. 7 F) (L 0.55 mm, W 0.42 mm) distinctly narrower than tergite VIII, central portion membranous.
Female. Unknown.
Measurements and ratios. Male (n = 1): TL 4.75 mm, PL 0.80 mm, PW 1.70 mm, EL 4.10 mm, EW 2.80 mm, TL/EW 1.7, PW/PL 2.1, EL/EW 1.5, EL/PL 5.1.
Distribution. Known only from the type locality in South Ecuador (Fig. 14).
Etymology. After terra typica, Ecuador.
