Holotype. Male, COSTA RICA. PUNTARENAS, Peninsula de Osa  , P.N. Corcovado, Estación Sirena, 0–100 m, 08° 28 ' 0 N, 083° 35 ' 0 W, LS 270500View Materials, 508300, June (G. Fonseca)( INBIO: CRIAbout CRI 001834190).

Derivation of specific name. The specific epithet, bonita  , is used as a noun in apposition and is based on the Estación Quebrada Bonita  in Carara National Park in reference to one of the places near which members of this species are found and secondarily to the beautiful colors of the adult.

Common name. Beautiful fungus dweller.

Diagnosis. With the attributes of the genus as described above and legs and tarsomeres concolorous, testaceous; distal antennomeres (5–11) brown. Eyes appearing slightly stalked from posterior aspect, markedly produced. Pronotum with hind angle acute, margin markedly constricted anterior to hind angle. Elytron with punctulae of interneurs moderately coarse in basal half, finer posteriorad.

Description. ( Fig. 1View FIGURE 1). Size small: ABL = 5.25 to 5.66 mm, SBL = 4.91 to 5.0 mm, TW = 2.66 mm. Color: Dorsum and venter rufescent; mouthparts, antennomeres 1–4 and legs testaceous; antennomeres 5–11 infuscated­brown. Metathorasic wings smoky grey. Luster: Ve r y s h i n 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, 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. 2View FIGURE 2) with ostium 1 / 5 its length, catopic, slightly constricted at basal third, basal third arched, apex markedly elongate, evenly rounded; endophallus with long flagellum, flagellum apex not barbed. Parameres asymmetric, left larger that right, right small.

Way of life. See above, Notes, under genus description. The known altitudinal range of this species is between sea level and 200 meters above sea level. They have been collected only west of the Cordillera Central in the lowlands in May, June and July, the lowland rainy season in Costa Rica, thus the adults are perhaps restricted to this season.
