The genus Berchmansus Navás, which was previously assigned to the tribe Leucochrysini, consists of three very rare species, all described from the Neotropics and all poorly known. Our report (1) provides the first description of a Berchmansus larva, the first instar of Berchmansus elegans (Guérin Méneville), (2) illustrates and redescribes the B. elegans adult, with emphasis on male and female genitalia, and (3) examines the larval and adult characters vis-à-vis the tribal affiliation of the genus. Given that the B. elegans adult and first instar share many apomorphies with other belonopterygine genera, this species belongs in the cosmopolitan tribe Belonopterygini, rather than the New World tribe Leucochrysini. Although Berchmansus larvae have not been collected in the field, we suspect that, like other belonopterygines, they are associated with ant nests. B. elegans exhibits a number of highly modified and unusual structures, some of which (#1 to #5) are not reported for any other chrysopids. Specifically: Males have (1) a unique, quadrate, dome-like hood above the gonarcus and (2) large, coiled parameres on the gonosaccus. First instars have (3) a greatly enlarged subapical seta on the flagellum, (4) a transverse row of long, hooked setae along the dorso-anterior margin of the pronotum, and (5) setose laterodorsal tubercles on the meso- and metathorax, with (6) multi-pronged, hooked setae.
