Isocondylus elongatus ( Lepeletier & Serville, 1825)

( Fig. 28 )

Isocondylus Amyot & Serville, 1843 and its only included species, I. elongatus , were both redescribed by Coscarón et al. (2008). Because Isocondylus is monotypic, I. elongatus is identified by the diagnostic characteristics of the genus such as the presence of short postantennal tubercles, the disc of hind lobe of pronotum unarmed ( Stål 1872) and a flat scutellum (Coscarón et al. 2008).Additionally, the elongated body and the general coloration and structure of I. elongatus allow an easy recognition of the species ( Fig. 28 ). Isocondylus elongatus was recorded from Argentina, Brazil and Bolivia ( Maldonado 1990), Colombia ( Forero 2006) and Venezuela (Coscarón et al. 2008). It is noteworthy that the latter authors did not mention the previous record of I. elongatus from Colombia and considered their record of it to Argentina as new. Gil-Santana & Zeraik (2003), in field observations, noticed that adults of I. elongatus , when disturbed, presented a behavior of vibrating wings and abdomen similar to wasps occurring in the same region (e.g. Apoica pallens (Fabricius, 1804) ; Hymenoptera : Vespidae ). They considered that similarities of the coloration seemed to reinforce the apparent mimicry.
