Type material.

Holotype male, BRAZIL: MG, Santuario do Caraça, Cascatona Trl. 20.071°S, 43.488°W, 1076 m, 16 March 2015, CH Dietrich, sweeping forest understory (2211) [UFRJ].

Diagnosis.

Pygofer with caudodorsal margin moderately produced, apex rounded, with two long and narrow processes subbasally, surpassing caudodorsal processes, apex acute; aedeagus somewhat tubular, shaft with serrated flange from subbase to subapex laterally on right, apex symmetrical, bifurcated, gonopore dorsal at apex between bifurcations; style approx. equal to length of aedeagus, very narrow with apical third enlarged, surface rugulose, apex lanceolate; Subgenital plate with very long hair-like setae densely.

Description.

Measurements. Male. Body length 7.6 mm; crown length 0.75 mm; width between eyes 0.73mm; eye width 0.88 mm; clypeus length 1.84 mm; clypellus length 0.99 mm; pronotum length 0.75 mm; mesonotum + scutellum length 0.76 mm. Female unknown.

External morphology. Medium sized, slender species. General color brown. Crown light brown with dark brown marks; pronotum and mesonotum brown with pale spots; eyes gray; forewing with pale spots along veins (Figure 21); face brown with dense light brown spots on clypeus and clypellus (Figure 23).

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).

Etymology.

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

Remarks.

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.
