(Figs. 7, 8, 33)

Holotype. Male, COSTA RICA. PUNTARENAS, Peninsula de Osa  , P.N. Corcovado, Estación Sirena, upper Ollas Trail, 30–150 m, 08° 29 ' 00” N, 083° 34 ' 39 ” W, June (Z.H. Falin)( KUNHM: ADP 106295).

Derivation of specific name. The specific epithet, osa  , is used as a noun in apposition and is based on the Peninsula de Osa  , in Corcovado National Park in reference to the area in which members of this species are found.

Common name. Osa  colorful fungus dweller.

Diagnosis. With the attributes of the genus described above and pronotum with margin broadly explanate, width greater than head across eyes; pronotum with hind angle obtuse, margin markedly constricted anterior to hind angle. Elytron with punctulae of interneurs moderately coarse in basal half, fine posteriorad. Elytra somewhat obscurely pigmented, only humeri and post scutellar area pale; legs and tarsomeres concolorous, testaceous.

Description. (Fig. 7). Size small: ABL = 5.0 to 5.58 mm, SBL = 4.66 to 4.91 mm, TW = 2.32 to 2.5 mm. Color: Dorsum of head and pronotum, and venter rufescent, elytra somewhat obscurely pigmented, only humeri and post scutellar area pale; mouthparts, antennomeres 1–4 and legs testaceous; antennomeres 5–11 infuscated­brown. Metathorasic wings smoky grey. Luster: Ve r y s h in y. Microsculpture: Absent. Head: Slightly broader across eyes than pronotum; frontal furrows shallowly impressed, very short; eyes large, produced; frons slightly convex, vertex moderately convex; ultimate labial palpomere slightly securiform; antennae of moderate length, reaching just posterior of humerus. Prothorax: Pronotum cordiform, moderately convex, side margin narrowly explanate, slightly produced at level of anterior setigerous pore, moderately sinuate anterior to obtuse hind angle. Base slightly lobed posteriorly. Pterothorax: Normal for Agrina, fully winged. Legs: Normal for Agrina. Abdomen: Sterna normal for Agrina, mostly glabrous, except normal paired ambulatory setae on sterna 3–5; males and females with two pairs long setae on sternum 6. Male genitalia: Phallus ( Fig. 8View FIGURE 8) with ostium 1 / 4 its length, catopic, constricted at basal third, basal third arched, apex markedly elongate, rounded; endophallus with long flagellum, flagellum apex not barbed. Parameres asymmetric, left larger that right, right small.

Dispersal potential. These beetles have been fogged from the canopy and are fully winged, thus they are likely good dispersers, as are most arboreal beetles.

Way of life. These beetles have been found by fogging fungus covered logs. The known altitudinal range of this species is between sea level and 150 meters above sea level. They have been collected only west of the Cordillera Central in the lowlands in June and July, the rainy season in Costa Rica.
