Paratype (): Costa Rica , Puntarenas, San Luis de Monteverde, 1100 m , 10°17'N 84°49'W , 4 June 2002 , L. M. LaPierre// leaf­miner in an unidentified Visaceae ( INBio ). Derivation of name . From uni (Latin= one) plus costa (Latin= rib) for the one costa on each elytron. Diagnosis . This species is in group 6 ( Uhmann 1937 ). It can be distinguished from all other species in group 6 by the sulcus on the inner margin of each eye, by antennomere II that is transverse, by the twelve rows of elytral punctures, and the single elytral costa. Description . Antennae, eyes, and elytra (except lateral and apical margins) black; head and pronotum (except base) rosaceous; femora yellow with black markings; tibiae black with yellow apices; tarsi yellow with black apices. Head: medial sulcus and sulcus on inner margin of each eye; vertex alutaceous; frons not angulate. Antenna: antennomere I subglobose; II transverse; III­V cylindrical, slightly sulcate; VI­X transverse; XI acutely pointed at apex; VIII­XI setose with golden setae. Pronotum: convex; lateral margin straight and divergent for basal 1/2, then sinuate and convergent to apex; each anterior angle with blunt tooth; surface coarsely, densely punctate except in area behind head along apical margin; strong transverse basal impression present; pronotal length 1.1 mm ; pronotal width 1.7 mm . Scutellum: quadrate; coarsely, densely punctate. Elytron: expanding to apex; lateral margin smooth; apical margin smooth; exterior apical angle with thin sharp tooth; sutural angle with acute tooth; humerus prominent, rounded; with 12 rows of punctures plus short scutellar row; interspace 4 strongly carinate for entire length; elytral length 6.4 mm ; elytral width 2.7 mm . Venter: prosternum slightly rugose medially, sparsely punctate laterally. Total length: 7.9 mm . Variation. Specimens vary in pronotal length from 1.1­1.4 mm , in pronotal width from 1.7­2.1 mm , in elytral length from 6.4­7.3 mm , in elytral width from 2.7­3.0 mm, and in total length from 7.9­9.3 mm . The color and sculpture is very similar to that of the holotype . Notes. This species is a leaf­miner in an unidentified species of Visaceae.
