Material examined. 2 Males. COSTA RICA, Puntarenas, District of Golfito, Guaycará, La Gamba Biological Station ; 8°42’2.49”N, 83°12’7.79”W; 80 m; IV. 2018; F. Etl. ( CAUD) (Map 4) GoogleMaps .

Description. Male (hitherto unknown). In addition to the characters of the genus: Tiny-size (5.0– 5.2 mm) ( Figs. 32A, B View FIGURE 32 , 33 View FIGURE 33 ). Body robust, granular, and moderately rugose ( Figs. 32 View FIGURE 32 , 33 View FIGURE 33 ). Coloration. Body dark brown ( Figs. 32A, B View FIGURE 32 ); ocelli white ( Fig. 34A View FIGURE 34 ); median pronotal carina with alternating ocher and dark brown spots along the entire edge of the hump ( Figs. 34 B, C View FIGURE 34 ); fore and middle tibiae ocher, with greyish-brown stripes ( Figs. 34B, D View FIGURE 34 ); hind tibia with basal half brown and an ocher ring near the base, distal half ocher; tarsomeres ocher with posterior edge brown ( Fig. 33A View FIGURE 33 ). Head taller than wide, eyes occupying a quarter of the cephalic capsule ( Figs. 32C View FIGURE 32 , 34A View FIGURE 34 ), medial carina protruding upward in the middle of the eyes, forming a prolongation, widened in lateral view and with a rounded edge ( Fig. 34B View FIGURE 34 ); lateral carinae moderately elevated, slightly protruding beside the eyes in frontal view ( Fig. 34A View FIGURE 34 ), dorsal margin almost straight, connecting with the base of the medial carina ( Fig. 34C View FIGURE 34 ); scutellum wide; fascial carinae diverging and straight in the basal section, then noticeably curving, outlining the scutellum and giving it a rounded shape; lateral ocelli located near the expansion of the frontal costa; medial ocellus situated in the middle of the distal section of the fascial carinae ( Figs. 34A View FIGURE 34 ). Thorax. Anterior margin of the pronotum moderately projected over the head ( Figs.33B View FIGURE 33 , 34C View FIGURE 34 ); prozonal carinae developed ( Fig. 34C View FIGURE 34 ); pronotal apex rounded ( Figs. 32B View FIGURE 32 , 33B View FIGURE 33 ). Hump rising in the anterior half of the pronotum, with the dorsal margin (median carina) slightly curved for most of its length, then curving downwards rapidly, progressively descending until reaching the pronotal apex in lateral view ( Figs. 33A View FIGURE 33 , 34B View FIGURE 34 ). Lateral lobes square-shaped, with a rounded lower margin in dorsal view ( Figs. 32B View FIGURE 32 , 33B View FIGURE 33 , 34C View FIGURE 34 ). Legs. Fore and mid femora with almost straight dorsal margin, ventral margin with three medium-sized prolongations ( Fig. 34B View FIGURE 34 ); fore tibia armed with small spinules on the distal third of the ventral margins; mid tibia unarmed ( Fig. 34D View FIGURE 34 ); hind femur robust ( Fig. 33A View FIGURE 33 ), median external area with two small lappets ( Fig. 33B View FIGURE 33 ), antegenicular and genicular tooth well-developed ( Fig. 33A View FIGURE 33 ); hind tibia armed with six small spines on each dorsal margin.Abdomen unmodified. Cerci conical and short, penultimate sternite conspicuous; subgenital plate triangular shaped in ventral view.

Remarks. Unfortunately, the pallial plates and epiproct of the studied males could not be examined as they are entirely covered, and attempting to observe them could damage the specimens. Additionally, the antennae are missing from the available specimens.

This species was originally described based on a female specimen from Gatun, Canal Zone ( Hebard, 1924a) ( Fig. 31 View FIGURE 31 ), and an additional male from Barro Colorado Island ( Panama) was selected posteriorly as an allotype ( Hebard, 1933) but was not described ( Fig. 32 View FIGURE 32 ). The specimens studied here are the first record of the species for Costa Rica ( Figs. 33 View FIGURE 33 , 34 View FIGURE 34 ). The males exhibit a similar morphology to the females, differing only in ambisexual characters. Furthermore, the males are morphologically similar to the male from Panama recorded by Kasalo et al. (2023b), and another Panamanian male recorded on iNaturalist. (https://www.inaturalist.org/observations/152111747), identified by Kasalo in 2023 ( Fig. 40B View FIGURE 40 ).
