Scaphytopius ancorus Arias-Paco & Godoy View in CoL , sp. nov.

( Figs. 1A–F View FIGURE 1 , 9A View FIGURE 9 , 10A View FIGURE 10 , 11B View FIGURE 11 , 12B View FIGURE 12 , 13B View FIGURE 13 )

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 View FIGURE 1 ). Face is pale white with multiple light brown spots on frontoclypeus, lorum, and anteclypeus; darker spots near lateral margins of gena ( Fig. 1C View FIGURE 1 ). Forewings brown with multiple dark spots widely distributed and numerous round white spots present (around 18–20), with approximately 11 veinlets ( Fig. 1B View FIGURE 1 ); 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 View FIGURE 9 ). Subgenital plate triangular, wider at base than apex, much longer than wide, with a row of 4–5 macrosetae along outer margin ( Fig. 10A View FIGURE 10 ), 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 View FIGURE 1 ). 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 View FIGURE 1 ). Aedeagus in lateral view V-shaped, with dorsal apodeme of similar length to shaft ( Fig. 1E View FIGURE 1 ); shaft in ventral view thin and tubular, with two lateral anchor-like spines at apex, distinguishable only in ventral view ( Fig. 1F View FIGURE 1 ) (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 View FIGURE 1 ). Aedeagus in lateral view V-shaped ( Fig. 1E View FIGURE 1 ), with two lateral spines at apex, in ventral view resemble an anchor ( Fig. 1F View FIGURE 1 ). 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 View FIGURE 1 ); shaft narrows toward apex ( Fig. 1D View FIGURE 1 ); apex of paraphyses in ventral view with two small needlelike distal processes extended very little, without reaching base of shaft ( Fig. 1D View FIGURE 1 ).

Distribution. Costa Rica.

Biology. Unknown.

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