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

(Figs. 5A–F, 9I, 10I, 11T, 12T, 13T)

Description. Length of male 4.18 mm. General appearance brown with multiple dark longitudinal spots and round white spots. Crown 1.8 x longer than basal width between eyes, pale brown, with thin black longitudinal line in center extending from base to 2/3 of crown length; faint pale V-shaped spot toward apex (Fig. 5A). Face mostly dark brown; gena margins orange-brown; apex of frontoclypeus black; apex of frontoclypeus with pale white transverse band in inverted V-shape, with small triangular spot below it (Fig. 5C). Forewings light brown, with dark spots in anteapical cells and dark brown elongated spot in discal cell; about 12 widely distributed, round white spots (Figs. 5A, B), 10 veinlets; veins dark brown. Legs with black femora, light brown tibiae and tarsi; posterior tibiae with black spots.

Male genitalia. In lateral view, the pygofer is triangular with rounded apex, with multiple macrosetae at apex (Fig. 9I). Subgenital plate triangular, wider at base than apex, much longer than wide, with row of 3–5 long macrosetae on external margin; with multiple punctures extending toward apex (Fig. 10I). Connective in ventral view U-shaped. Style in ventral view with apophysis very short, robust, and pointed at apex; space between preapical lobe and apophysis C-shaped (Fig. 5E). Paraphyses absent. Aedeagus in lateral view strongly curved, giving the appearance of wide U-shape (Fig. 5D); preatrium length similar to shaft; dorsal apodeme shorter than shaft; straight toward apex; shaft tubular, curved dorsally; in ventral view, shaft is compact up to half its length, where it divides into three projections (Fig. 5E): central projection where the gonoduct and gonopore are located, and two lateral projections in form of spines that project beyond central projection; in apical view two lateral projections are directed opposite to gonopore (Fig. 5F). Gonopore in subapical position, located between two lateral spines (Fig. 5F).

Diagnosis. Aedeagus with shaft that, at half its length, divides into three projections, with central projection containing gonoduct and gonopore, and lateral projections positioned to either side of it (Fig. 5E.). Lateral projections are longer than central projection and acquire opposite directions toward apex (Fig. 5F).
