Onota angulicollis (Reiche)

( Figs. 21 , 22 , 37 )

Lebia ? angulicollis Reiche 1842:312 . Holotype male, found and labeled by H. Reichardt in MNHP (Muséum National d'Histoire Naturelle, Paris). Type area: COLOMBIA.

Common name. Reiche's angle­necked carabid beetle.

Diagnosis. With the attributes of the genus as described above and head, prothorax, venter, and appendages testaceous; elytra metallic blue. Sides of pronotum narrowly explanate, moderately sinuate anterior to hind angle, subangulate at mid­lateral setigerous pore.

Description. ( Fig. 21 ). Size small: ABL = 5.42 to 6.42 mm, SBL = 4.5 to 5.92 mm, TW = 2.16 to 2.5 mm. Color: Head, prothorax, venter and appendages testaceous; elytra metallic blue or blue­green. Metathorasic wings grey. Luster: Dorsal and ventral surfaces very shiny. Microsculpture: Head, pronotum, and elytra with transverse meshes. Head: Slightly broader across eyes than pronotum; frontal furrows absent except for small grooves at margin of clypeus; frons convex; eyes large, hemispheric; ultimate labial palpomere fusiform; antennae of moderate length, reaching just posterior of humerus. Prothorax: Moderately convex, side margin narrowly explanate, subangulate at mid­lateral setiferous pore, moderately sinuate anterior to hind angle. Pterothorax: Normal for Agrina, fully winged. Legs: Normal for Agrina. Abdomen: Sterna normal for Agrina, glabrous, except 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. 22 ) with ostium of 1/5 its length, apex short, rounded; phallus catopic; internal sac with long flagellum, flagellum apex not barbed. Parameres asymmetric, left larger that right, right very small.

Way of life. Member of this genus are arboreal, or at least they are found off the ground. The Florida species runs on the leaves of the common Sabal palmetto. The ALAS project has collected them by fogging the tree Meliosma vernicosa (Liebm.) Griseb. Nevermann found them on rotten logs and by beating dry leaves of the palm Cryosophila warscewiczii (H. Wendl.) Bartlett. In South America, I have collected them commonly with insecticidal fogging techniques from the rain forest canopy, suspended dry leaf clumps, and from dead palm fronds hanging on Astrocaryum murumuru Mart .. The known altitudinal range of this species is between 10 and 650 meters above sea level. Adults have been obtained in all months of the year and they are widespread on both sides of the Cordillera Central and active in both the dry and rainy seasons in the lowlands.
