Valeriaaschero nigrita Erwin View in CoL , new species
(Figs. 11, 12, 13)
Holotype. Male. COSTA RICA: Puntarenas, Peninsula de Osa, Rancho Quemado, 200 m, 8° 40' 44" N, 83° 34' 00" W, LS292500,511000, September (F.A. Quesada)( INBio: CRI 001408247).
Derivation of specific name. Members of this species resemble the preceding species except in coloration, hence the Latin adjective, niger, from which nigrita is derived, suggests the color of their dark elytra and infuscated pronotum.
Common name. Valeria’s somber arboreal carabid.
Diagnosis. With the attributes of the genus and top of head bright rufous contrasting markedly with dark genae, testaceous antennae, and elytra shiny piceous.
Description. (Fig. 11). Size medium: ABL = 6.3 mm, SBL = 5.7 mm, TW = 2.4 mm. Color: Pronotum shiny piceous with rufous lateral explanations; elytra shiny piceous; head with entire top bright rufous; appendages and venter partially infuscated, partially dark rufous. Luster: Very shiny throughout. Microsculpture: Effaced from dorsal surfaces. Head: Slightly wider than pronotum across eyes; frontal furrows markedly impressed to posterior margin of eyes; frons with convex callous at middle; eyes large, markedly produced; ultimate labial palpomere securiform; antennae of moderate length, reaching just posterior of humerus. Prothorax: Narrow, quadrate, markedly convex, margins moderately explanate, sinuate before moderately produced acute hind angles. Pterothorax: Normal for Agrina, fully winged. Legs: Normal for Agrina. Abdomen: Normal for Agrina; glaborous, except normal ambulatory setae on sterna 3–5 and males with two pair of ambulatory setae on sternum 6, female unknown. Male genitalia: Aedeagus — phallus tubular, catopic, apex moderately long and narrow, endophallus without armature, parameres small, right more so than left ( Fig. 12 View FIGURE 12 ).
Dispersal potential. These beetles are fully winged and likely are good dispersers, as are most arboreal beetles.
Way of life. These beetles belong in a subtribal level clade in which all the species are arboreal, however the single know specimen’s method of capture was not recorded. Geographic distribution. ( Fig. 13 View FIGURE 13 ). Known only from Costa Rica.
