Paracodilia geniculata sp. n.

The generic name refers to the similarity between the new genus and Codilia Nielson, 1982.

General color deep brown. Crown light brown with distal 1/4 orange, pronotum and mesonotum pitchy without spots; eyes piceous; forewing with distinct yellow mark on clavus, veins without spots (Figs 1, 2). Face fuscous (Figure 3).

Anterior margin of head obtusely angled. Crown midlength produced distally beyond eyes, approx. 1⁄3 of entire length; area between eyes as wide as eye width, surface rugulose, elevated above eyes; lateral margins slightly carinate, not surpassing anterior margin of eyes, slightly convergent basally. Medial length of pronotum distinctly longer than crown and quite shorter than mesonotum (Figure 1). Forewings typical of subfamily (Figure 2). Clypeus long and narrow, lateral margins slightly convex; clypellus broad, maximum width approx. equal to midlength, base inflated, lateral margins constricted medially (Figure 3).

Paracodilia geniculata sp. n. Holotype: 1 habitus, dorsal view 2 habitus, lateral view 3 face 4 pygofer and segment X, ventral view 5 pygofer, aedeagus, connective, style and segment X, lateral view 6 aedeagus, connective and style, ventral view 7 aedeagus, lateral view 8 style, lateral view 9 subgenital plate, ventral view. Scale bars: 1 mm (1–3), 0.5 mm (4–9).

Valve triangulate in ventral view. Pygofer narrow in lateral aspect, caudodorsal margin produced and tapered in lateral view, without triangular plates at base (Figure 4), caudoventral processes short, covered with short spines, adjacent to base of caudodorsal processes (Figure 5). Segment X elongate, lateral margins parallel in ventral view (Figure 4). Aedeagus moderately long and narrow, somewhat tubular, bent at midlength in lateral aspect, apex asymmetrically bifurcate; gonopore apical on ventral surface between bifurcations (Figs 6, 7); dorsal connective absent. Connective large, Y-shaped with stem broad, shorter than length of arms (Figure 6). Style very long, much longer than aedeagus, sinuate in lateral view, tapered to acute apex (Figs 6, 8). Subgenital plate narrow, lateral margin abruptly tapered distally with dense setae (Figure 9).

This new genus is similar to genus Codilia Nielson, 1982 externally, but has very different male genitalia. The aedeagus is distinctly curved at midlength in lateral view and apex asymmetrically bifurcate, but in Codilia the aedeagus is slightly curved with a large retrorse spine at the apex. Also in the new genus the subgenital plate is highly setose laterally in its apical half but sparsely setose in Codilia.

Pygofer with caudoventral processes short, covered with short spines, adjacent to base of caudodorsal processes; aedeagus somewhat tubular, bent at midlength in lateral aspect, apex asymmetrically bifurcate, gonopore apical on ventral surface between bifurcations, dorsal connective absent; style much longer than aedeagus, tapered to acute apex; subgenital plate with dense setae.

Body length 7.59 mm; crown length 0.65 mm; width between eyes 0.84 mm; eye width 0.68 mm; clypeus length 1.52 mm; clypellus length 0.83 mm; pronotum length 0.74 mm; mesonotum + scutellum length 1.00 mm. Female unknown. External morphology and male genitalia as described in generic diagnosis.

The species epithet is derived from the Latin word geniculus, referring to the aedeagus being geniculate or bent medially in lateral view.

Boliviela expanda sp. n. Holotype: 10 habitus, dorsal view 11 habitus, lateral view 12 face 13 pygofer and segment X, ventral view 14 pygofer, aedeagus, connective, style, dorsal connective and segment X, lateral view 15 aedeagus and dorsal connective, lateral view 16 aedeagus and dorsal connective, dorsal view 17 style, lateral view 18 apex of style, ventral view 19 connective, caudal view 20 subgenital plate, ventral view. Scale bars: 1 mm (10–12), 0.5 mm (13–20).

Anterior margin of head obtusely angular. Crown midlength produced distally approx. 1⁄3 of entire length; area between eyes approx. as wide as eye width, surface without wrinkles, elevated above level of eyes; lateral margins parallel, slightly carinate, surpassing anterior margin of eyes distally. Medial length of pronotum longer than crown but shorter than mesonotum (Figure 10). Clypeus long, narrow, lateral margins convex basally; clypellus broad, maximum width approx. equal to midlength, base inflated, lateral margins constricted medially, tapered apically (Figure 12).

Male genitalia. Pygofer short, caudodorsal margin produced as a curved, tapered process (Figure 14), basally with a triangular plate on each side, caudoventral processes subbasally, very long, apex slightly enlarged in lateral aspect, extended beyond caudodorsal processes; segment X broad and long with lateral margins parallel in ventral view (Figure 13). Aedeagus large and broad, lateral edge rolled ventrally, tapered to compressed apical 1/4 in lateral view, apex curved dorsally; gonopore subapical on lateral surface; dorsal connective bifurcate at base, enclosing aedeagus subbasally (Figs 15, 16). Connective very small, Y-shaped, anterior stem very short (Figure 19). Style long, reaching to apex of aedeagus, needle-like with apical third enlarged, corrugated, a small process at subapex (Figs 17, 18). Subgenital plate narrow, outer lateral margin convex at apical third, tapered to apex, dense hair-like setae at apical half (Figure 20).

The specific epithet is descriptive of the expanded aedeagus in dorsal and lateral views.

The new species keys to Collasuyusana Nielson in Nielson (2011), but its aedeagal shaft is atypical of this genus. We therefore provisionally assign the species to Boliviela based on the inflated aedeagal shaft, despite the dorsal connective being atypical of this genus. According to Prof. Nielson, retired faculty of Brigham Young University (pers. com.) the aedeagus holds historically a higher diagnostic value than the dorsal connective.

Armaturolidia symmetrica sp. n. Holotype: 21 habitus, dorsal view 22 habitus, lateral view 23 face 24 pygofer and segment X, ventral view 25 pygofer, aedeagus, connective, style, dorsal connective and segment X, lateral view 26 aedeagus and dorsal connective, lateral view 27 aedeagus, dorsal view 28 style, lateral view 29 dorsal connective, dorsal view 30 connective, caudal view 31 subgenital plate, ventral view. Scale bars: 1 mm (21–23), 0.5 mm (24–31).

Anterior margin of head angular. Crown in middle produced distally approx. 1⁄3 of entire length; area between eyes apparently narrower than width of eyes, surface without wrinkles, elevated above level of eyes; lateral margin slightly carinate, surpassing anterior margin of eyes distally, slightly convergent basally. Median length of pronotum about equal to length of crown and mesonotum (Figure 21). Clypeus elongate, lateral margins convex; clypellus narrow, basal width less than 2/3 midlength, base flattened and narrow, apex slightly expanded (Figure 23).

Male genitalia. Pygofer with caudodorsal margin moderately produced, apex rounded; triangular plates at base of pygofer, two long and narrow processes subbasally, surpassing caudodorsal processes, apex acute; segment X elongate, slightly constricted medially in ventral view (Figs 24, 25). Aedeagus elongate, somewhat tubular, apical half recurved dorsally, shaft with serrated flange from subbase to subapex laterally on right, apex symmetrical, bifurcated; gonopore dorsal at apex between bifurcations (Figs 26, 27); dorsal connective very short, narrow, slightly bifurcate at base (Figure 29). Connective very small, Y-shaped, stem shorter than length of arms (Figure 30). Style very long, approx. equal to length of aedeagus, very narrow with apical third enlarged, surface rugulose, apex lanceolate (Figure 28). Subgenital plate narrow, outer margin convex medially and tapered to apex, with very long hair-like setae densely (Figure 31).

The species epithet is named for the aedeagus apex being symmetrically bifurcate.

The new species keys to genus Armaturolidia Nielson in Nielson (2011), but the general color of brown with pale marks is different from the original diagnosis of that genus (unicolorous or with black band). This species is close to A. denticulata Nielson, 1986 in some male genitalia characters but can be separated by the lateral margin of crown extending beyond eyes, caudodorsal processes of pygofer not bilobed, style equal to aedeagus in length and apex enlarged, and aedeagus apex symmetrically bifurcate.
