(Figs. 15, 16, 35)
Pseudometabletus nevermanni Liebke 1930:723. Holotype, male, COSTA RICA. LIMÓN, Rio Reventazon, Ebene, Hamburg Farm, 10 m, 10° 15' 0 N, 083° 28' 0 W, July (NMNH: ADP009555).
Cylindronotum nevermanni van Emden, 1949:891. New homonymy, new synonymy.
Derivation of specific name. The specific epithet, nevermanni, was used by Liebke as a noun in apposition based on the last name of Ferdinand Nevermann, who was superb at collecting carabid beetles in Costa Rica, especially on his own farm (Hamburg Farm) and in its vicinity and who has contributed significantly to our knowledge of the species richness represented in Costa Rica. The NMNH collection, where his collection was ultimately deposited, vouchers his efforts.
Common name. Nevermann's drab­brown carabid beetle.
Diagnosis. With the attributes of the genus as described above and color completely brown, except for testaceous 4 basal antennomeres; dorsal surface shiny.
Description. (Fig. 15). Size small: ABL = 4.66 to 5.08 mm, SBL = 4.33 to 4.66 mm, TW = 1.66 mm. Color: Brown to piceous overall. Luster: Surface shiny. Microsculpture: Effaced from head and pronotum; shallowly engraved isodiametric meshes on elytra. Head: Subequal across eyes to width of pronotum; frontal furrows absent except for small groove at margin of clypeus; frons slightly convex; eyes moderately small, slightly produced; ultimate labial palpomere sub­securiform; antennae of moderate length, reaching just posterior of humerus. Prothorax: Moderately convex, side margin narrowly beaded, evenly rounded at anterior marginal seta, moderately sinuate anterior to hind angle. Pterothorax: Normal for Agrina, fully winged. Legs: Normal for Agrina. Abdomen: Sterna normal for Agrina, setiferous, setae scattered, except normal ambulatory setae on sterna 3– 5 and both males and females with two pairs on sternum 6. Male genitalia: Phallus (Fig. 16) with ostium of 1/3 its length, apex elongate, narrow; phallus narrow, twisted, catopic; internal sac with long flagellum, flagellum apex not barbed. Parameres asymmetric, left larger that right, right very small.
Dispersal potential. Adults are fully winged, thus they are likely good dispersers, as are most arboreal beetles.
Way of life. Beetles in this genus have been fogged from the canopy in South America. Wendy Porras, INBio parataxonomist, collected individuals by sweeping a plant in the family Convolvulaceae. The known altitudinal range of this species is between 10 and 1300 meters above sea level. Adults have been collected only east of the Cordillera Central in March, June, July, and August, hence both dry and rainy seasons at low to middle altitudes.

Geographic distribution. (Fig. 35). Known only from lower Central America from Costa Rica south to Colombia.
Notes. Cylindronotum nevermanni van Emden was described from a female (COSTA RICA. LIMÓN, Rio Reventazon, Ebene, Hamburg Farm, 10 m, 083°28'W, 10°15'N, September) by van Emden (1949), and supposedly deposited in the NMNH (ibid: page 891). However, it is not in the NMNH collection (Erwin & House 1978). Apparently, van Emden was unaware that Liebke (1930) described the same species with the same patronymic and with the same Nevermann specimens, but in Liebke's own new genus placed in the wrong higher taxon, the Colliurinae.
