Diagnosis. Staminodeus inermis is distinguished from the other species of Staminodeus by the small size, the light reddish­brown color (but see section on variation in generic description); the short distance between the eyes, the ventrally inermous prothoracic leg in males; and the fairly short frontal spine in females.

Male. Very small, length 1.2–1.3 mm, width 0.6–0.7 mm, l/ w 1.9 –2.0, light reddishbrown. Rostrum 0.3 mm, r/p 0.9–1.0. Eyes separated by distance similar to breadth of antennal club. Frons glabrate, slightly protruded. Pronotum l/ w 0.8, slightly convex. Prosternum similar in length to mesosternum, slightly convex. Profemur ( Fig. 3a View Fig. 3 ) slightly sinuate, f/p 1.0–1.3, greatest width near apical 2/5, ventrally inermous; protibia ( Fig. 3a View Fig. 3 ) subrectate, t/f 0.8–0.9, anteroventral margin inermous, apically mucronate, promucron nearly 2/3 as long as protarsal claw; mesotibia apically mucronate, mesomucron nearly 1/4 as long as mesotarsal claw. Elytron l/ w 1.3 –1.5 (N 15). Wing/body 1.3–1.5, wing l/ w 2.9 –3.7. Median lobe ( Fig. 4a View Fig. 4 ) l/ w 2.6 –3.0 (N 5), laterobasal sclerites apically broadened, denticulate, median sclerite plicate, apical rami basally diverging, apically fused into triangular projection, basal 1/3 of median lobe denticulate, aedeagal apodemes shorter than median lobe.

Female. Length 1.1–1.4 mm, width 0.6–0.7 mm, l/ w 1.9 –2.0. Rostrum 0.3–0.4 mm, r/p 1.0–1.2. Eyes separated by distance slightly greater than breadth of antennal club. Frontal spine nearly 1/3 as long as diameter of eye. Pronotum l/ w 0.7 –0.8. F/p 0.9– 1.3; t/f 0.7–1.0, protibia apically mucronate, promucron nearly 1/4 as long as protarsal claw. Elytron l/ w 1.3 –1.5 (N 15). Wing/body 1.4–1.5, wing l/ w 3.1 –3.6 (N

5). Spermatheca ( Fig. 5a View Fig. 5 ) deflexed nearly 135, apex acute.

Etymology. Named for the male plesiomorphy of lacking ventral denticulation on the prothoracic leg— inermis signifying ‘‘unarmed’’ ( Nichols 1989).

Distribution. Staminodeus inermis has been collected on the Carribean slope of Panama, Provincia Bocas del Toro, Río Changuinola ( Fig. 6 View Fig. 6 ).
