Despite this recent phylogenetic progress, the Neotropical fauna of potter wasps remains little explored, a fact that is particularly noticeable by the poor representation of the group in most Latin American entomological collections. In fact, the group is not as abundant as the social vespids, and few experts are carrying out research within the group. Nevertheless, the number of described species has been increasing constantly for the Neotropics (e.g.

Type specimens of species potentially closely related to the new species were examined from the cited institutions (details in the taxonomic catalog). All examined specimens were dry pinned preserved ones. Examination was undertaken with a Leica S8 APO stereomicroscope. Photographs of structures of interest were obtained with a Canon EOS Rebel T6 digital camera attached to the stereomicroscope. The same camera with a Canon Macro 100 mm lens and a Yongnuo 2x Extensor were used for photographing specimen habitus. All images were captured using Canon EOS Utility software and using a light dome modified from
Body length is taken from the frons to the hind border of T2 and expressed as an approximate measurement, as body position can modify it more or less substantially. Wing length is taken from the humeral angle of the wing at the border of the tegula to the wing tip and expressed as an approximate measurement, as wing position can affect the total measurement.
This is the only species of
Body length (from head to apex of T1): 5.5 mm; Forewing length (from mid tegula to apex): 6.07 mm.
Body with predominantly brown-yellowish tegument. Yellow head, with a wide oval black mark on the frons, connected to a narrow black band extending to the occiput; brownish mark in the center of the clypeus. Mesosoma and metasoma with predominantly brown-yellowish tegument. Antennae with brownish scape and pedicel; progressively darker flagellum from the base to the apex. Mesoscutum totally blackened. Scutellum with a central black-brown spot. Brownish propodeum. Black mark in the basal portion of T1. Yellow marks more prominent in the regions that follow: parategulae; apical margin of T1; lateral and apical margins of T2; apical margin of S1. Brown wings.
Labrum truncated. Clypeus broader than long, with short and emarginated apex; small and not carinate apical teeth present. Interantennal region without cariniform elevation. Pronotal carina well developed in all its extension, in the shape of an inverted “V” in frontal view, with a well-developed lateral lamella. Lateral surface of pronotum narrow, with the distance between pronotal fovea and the mesepisternum smaller than the size of the fovea itself; pronotal fovea slit-shaped. Pretegular carina absent. Parategulae triangular. Sulcus between the scutellum and metanotum obsolete. T1 elongated, with basal portion longer than the apical portion; two lateral longitudinal carinae present, not reaching half of the segment; preapical fossa absent. T2 oval, longer than wide, with lamella well developed. S2 without abrupt basal elevation.
Clypeus without evident punctation. Frons and vertex with deep, coarse and abundant punctures, with space between them smaller than the size of a puncture. Pronotum with granular punctation, with shallow, abundant and slightly thickened punctures, distance between them smaller than the size of a puncture. Mesespisternum with deep punctures, denser in its upper portion; shallow and slightly evident punctures in its lower portion. Mesoscutum, scutellum and propodeum with deep and coarse punctures. Apex of T1 with evident shallow punctation. T2 with well-marked deep punctation, distance between them smaller than the size of a puncture.
Golden pubescence covering the entire surface of the body. Bristles shorter, thick and abundant on clypeus, frons, vertex, and mesosoma. Elongated, delicate and thin bristles in the metasoma.
Unknown.

This species is named after the Panamanian Biologist Jean Carlos Ábrego.
Representatives of
Body length (from head to apex of T1): 5.10 mm; Forewing length (from mid tegula to apex): 6.50 mm.
Body with predominantly blackish tegument. Yellow marks as follows: stripes on inner margin of compound eyes; upper surface of the gena; narrow range in the antero-dorsal region of pronotum; narrow bands in the distal portions of the T1–T6 and S2–S6. S1 brownish. Antennae brownish. Yellow-brownish legs. Brownish wings.
Labrum rounded, narrow. Clypeus broader than long, apically curved backwards and with short, concave and emarginated apex; small and ecarinate apical teeth present, with small distance between each other. Interantennal region without cariniform elevation. Pronotal carina well developed dorsally, gently and roundly recurved in the humeral region. Lateral surface of pronotum narrow, with the distance between pronotal fovea and the mesepisternum smaller than the size of the fovea itself. Pretegular carina absent. Parategulae pointed. Sulcus between scutellum and metanotum obsolete. T1 distinctly filiform with basal region of greater length than the apical portion; two lateral longitudinal carina present; preapical fossa present. T2 wider than long, outlined as a half oval in dorsal view; well-developed apical lamella. S2 without basal slope followed by an elevation.
Clypeus without evident punctation. Frons and vertex with evident and abundant punctures, with distance between them approximately smaller than the size of a puncture; micro-punctation evident. Pronotum, upper portion of the mesepisternum, mesoscutum, scutelum, metanotum and propodeum with deep and abundant punctures, with distance between punctures smaller than the size of a puncture. Lower portion of the mesepisternum with shallow and sparse punctures, distance between them approximately greater than the size of a puncture. T1 unpunctate. T2 with micro-punctation evident.
Fine whitish pubescence covering the entire body. Whitish bristles covering the head, concentrated in the clypeus. Brownish, short and thin bristles on mesosoma. Brownish and long bristles on T1–T6 and S2–S6.
Unknown.

Here we have the opportunity to correct the date of Bertoni’s paper “Hymenópteros nuevos o poco conocidos”. Though considered as published in December of 1925, as suggested in the heading of its cover, issue 2(1) of the “Revista de la Sociedad Científica del Paraguay”, was actually printed in 1926, as indicated in the foot of the very same cover.
