(Figs. 19, 20, 36)

Hyboptera dilutior Ball and Bousquet 2001:113 (not Oberthür 1884).

Holotype. Male. USA. TEXAS, Hidalgo County, Mission; Bentsen State Park, 26º 10' 22" N, 098º 22' 56" W, July (W.E. Steiner)( NMNH: ADP007623).

Derivation of specific name. The specific epithet, auxiliadora , is used as a noun in apposition based on the middle name of Mariá Auxiliadora Sanchez, who for many years was responsible for the welfare of participating visiting taxonomists at INBio and its facilities and who made life easy therein while we undertook our studies of the rich Costa Rican fauna and flora .

Common name. Auxiliadora's humped­wing carabid beetle.

Diagnosis. With the attributes of the genus as described above and elytral ground color black, surface with scattered metallic or brassy reflections; interval 5 with 6 tubercles.

Description. (Fig. 19). Size medium: ABL = 5.58 to 5.83 mm, SBL = 5.50 to 5.66 mm, TW = 2.92 to 3.16 mm. Color: Head and pronotal disc infuscated, elytra flavous with testaceous and piceous patches; mouthparts, appendages, margin of prothorax testaceous, venter infuscated. Metathorasic wings clear. Luster: Ve ry s hi n y. Microsculpture: Dorsal surface with isodiametric meshes, less impressed on elytra. Head: Markedly broad, not as broad as pronotum; clypeus bi­carinate, carinae joining a midpoint; frons and occiput markedly and irregularly rugose; eyes very large, hemispheric, markedly produced; ultimate maxillary palpomere securiform, ultimate labial palpomere securiform and concave with margin of setae; antennae short, barely reaching humerus. Prothorax: Convex, disc transversely and irregularly rugose, side margin markedly explanate, straight to anterior hind angle, base medially lobed posteriorly. Pterothorax: Normal for Agrina, fully winged. Legs: Normal for Agrina. Abdomen: Setiferous; normal ambulatory setae on sterna 3–5 and males with one pair of ambulatory setae on sternum 6, females with two pairs on sternum 6. Male genitalia: Phallus ( Fig. 20 ) with ostium 1/4 length, catopic, and apex short and evenly rounded, endophallus with flagellum, flagellum not barbed. Parameres asymmetric, right very small, left very large.

Dispersal potential. The wings are fully developed and adults of other species of this genus are known to occur in the canopy of tropical forests, thus it is likely that this species is a moderate to strong flyer.

Way of life. See under genus and the known altitudinal range of this species is between 10 and 240 meters above sea level. The holotype was collected by W. Steiner from under bark of the tree Celtis levigata Willd. Vogt collected another individual from under the web tent of a psocid colony. Adults have been obtained in March, April, May, July, August, and September, hence they are active in both the dry and rainy seasons in the lowlands on both sides of the Cordillera Central.
