Scaphytopius ancorus Arias-Paco & Godoy, sp. nov.

(Figs. 1A–F, 9A, 10A, 11B, 12B, 13B)

Description. Length of male 3.80–3.83 mm. General appearance brown. Crown 1.4 x longer than basal width between eyes, pale white with numerous longitudinal brown spots forming nearly continuous band between eyes and another toward apex (Fig. 1A). Face is pale white with multiple light brown spots on frontoclypeus, lorum, and anteclypeus; darker spots near lateral margins of gena (Fig. 1C). Forewings brown with multiple dark spots widely distributed and numerous round white spots present (around 18–20), with approximately 11 veinlets (Fig. 1B); veins light brown, with third and fourth apical cell with white outer edge. Legs light brown with black spots on tibiae and femora.

Male genitalia. Pygofer in lateral view triangular, with acuminate apex and multiple macrosetae at apex (Fig. 9A). Subgenital plate triangular, wider at base than apex, much longer than wide, with a row of 4–5 macrosetae along outer margin (Fig. 10A), and 4 thin elongated setae at apex. Connective in ventral view W-shaped. Style in ventral view with apophysis thin, truncated at apex; space between preapical lobe and apophysis C-shaped (Fig. 1D). Paraphyses in ventral view short preceding aedeagus, of similar length to shaft, divided by narrow longitudinal space at base, connected by a membrane; apex with two small needlelike distal processes extended very little, without reaching base of shaft (Fig. 1D). Aedeagus in lateral view V-shaped, with dorsal apodeme of similar length to shaft (Fig. 1E); shaft in ventral view thin and tubular, with two lateral anchor-like spines at apex, distinguishable only in ventral view (Fig. 1F) (not visible in lateral view); preatrium absent. Gonopore apical.

Diagnosis. Paraphyses in ventral view of similar length to shaft, divided by small membranous space longitudinally (Fig. 1D). Aedeagus in lateral view V-shaped (Fig. 1E), with two lateral spines at apex, in ventral view resemble an anchor (Fig. 1F). This species is distinguished from S. piperatus, by the following features: Shaft in ventral view with two lateral, anchor-like spines at apex, long and curved upward (Figs. 1D, F); shaft narrows toward apex (Fig. 1D); apex of paraphyses in ventral view with two small needlelike distal processes extended very little, without reaching base of shaft (Fig. 1D).

Distribution. Costa Rica.

Biology. Unknown.

Etymology. From Latin ancora (anchor), referring to the similarity of the aedeagus apex in ventral view to an anchor.
