Treatment

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

( Figs. 7G–L View FIGURE 7 , 9N View FIGURE 9 , 10M View FIGURE 10 , 11 View FIGURE 11 AA, 12AA, 13AA)

Description. Length of male 4.51 mm. General appearance light brown with irregular transparent spots. Crown 1.4 x longer than basal width between eyes, light brown, with two longitudinal pale white bands in center, separated by black line that extends to two-thirds of crown’s length; after this point, bands merge to form single band at apex ( Fig. 7G View FIGURE 7 ). Face entirely black, with two white transverse bands in shape of inverted V at apex of frontoclypeus, and faint white band on external margin of gena that extends to eye ( Fig. 7I View FIGURE 7 ). Forewings light brown; clavus cells with irregular white spots, discal and anteapical cells with irregular white spots, with 9 veinlets ( Fig. 7H View FIGURE 7 ); veins dark and light brown. Legs with black femora; light brown anterior and middle tibiae, black posterior tibiae, and light brown tarsi.

Male genitalia. Pygofer in lateral view rectangular, with rounded apex, multiple macrosetae at apex ( Fig. 9N View FIGURE 9 ). Subgenital plate triangular, much wider at base than apex, longer than wide, with row of long thin setae at apex ( Fig. 10M View FIGURE 10 ). Connective in ventral view in shape of wide U. Style in ventral view with apophysis short and rounded, without spines and with rounded internal margin; space between preapical lobe and apophysis C-shaped ( Fig. 7J View FIGURE 7 ). Paraphyses fused at base, diverging slightly and gradually beyond midlength in ventral view, giving appearance of inverted V ( Fig. 7J View FIGURE 7 ). Aedeagus in lateral view very short, L-shaped ( Fig. 7K View FIGURE 7 ); preatrium absent; dorsal apodeme longer than shaft, straight toward apex; shaft straight and tubular, in apical view with two small lateral spines and third, larger dorsal spine in gonopore area ( Fig. 7L View FIGURE 7 ). Gonopore in subapical position, at base of dorsal spine.

Diagnosis. Style apophysis in dorsal view without spine on internal margin and rounded in shape ( Fig. 7J View FIGURE 7 ). Connective in shape of open U. Paraphyses fused at base, diverging slightly beyond midlength in dorsal view, forming inverted V ( Fig. 7J View FIGURE 7 ). Dorsal apodeme longer than shaft and straight toward apex (in contrast to S. hansoni , which is curved) ( Fig. 7K View FIGURE 7 ).

Distribution. Costa Rica.

Biology. Unknown.

Etymology. From the Latin vulcanus , because it was collected on the Cacao Volcano in Costa Rica.
