Figure 6 - Aedeagal characters (male genitalia) representing the different morphological types found in or sample of Helopini: A evident setae (57: 0) representing the helopiod type (Nabozhenko 2001b, 2002a, 2005), distributed over half of the parameres (58:0), illustrated from Helops caeruleus (Linnaeus), not included in the analysis (lateral view) B evident setae (57:0); representing the catomoid type (Nabozhenko 2006), distributed over two thirds of parameres (58:1) in Nautes fervidus Pascoe C not evident setae over parameres (57:1) representing the nalassoid type (Nabozhenko 2001b, 2002a, 2002b), illustrated from Odocnemis californicus Mannerheim D parameres not convergent (59:1), with blunt apex (62:0) in Helops caeruleus (ventral view) E parameres not convergent (59:1) with weakly constricted apex (61:1) in Nautes fervidus F parameres convergent (59:0), with acute (60:1) not constricted apex (62:1) in O. californicus.
