STEPHANODES Enock, 1909 View in CoL View at ENA

( Figs 942–978 View FIGURE 942 View FIGURES 943–946 View FIGURES 947–949 View FIGURES 950–954 View FIGURES 955–960 View FIGURES 961–969 View FIGURES 970–973 View FIGURES 974–978 )

Stephanodes Enock, 1909: 457 View in CoL . Type species: Stephanodes elegans Enock, 1909 , by monotypy.

Eustephanodes Ogloblin, 1967: 194 . Type species: Eustephanodes missionicus Ogloblin, 1967 , by original designation. Synonymy by Yoshimoto, 1990: 72.

Masonana Yoshimoto, 1990: 63 . Type species: Masonana polynemoides Yoshimoto, 1990 , by monotypy. Synonymy by Huber & Fidalgo, 1997: 34.

Diagnosis. Body length 970–1205 μm. Vertex with large shallow depressions outside each ocellus ( Figs 952 View FIGURES 950–954 , 955– 958 View FIGURES 955–960 ); scape with inner surface rasp-like ( Fig. 946 View FIGURES 943–946 ); mesonotal spiracle much closer to anterior apex of notaulus than to dorsal apex of prepectus ( Fig. 962 View FIGURES 961–969 ), mesosoma and metasoma smooth ( Figs 961–966 View FIGURES 961–969 ) and shiny ( Fig. 942 View FIGURE 942 ); fore wing with parastigma slightly elongate ( Fig. 949 View FIGURES 947–949 ).

Discussion. Among the nine other Nearctic genera of this group ( Acmopolynema , Caraphractus , Cnecomymar , Eustochus , Kalopolynema , Mymar , Neomymar , Palaeoneura , Polynema ), Stephanodes is distinguished by the diagnostic features listed above. As is usual among this group of genera, different features taken alone suggest different relationships among the genera. For example, Stephanodes has faint subantennal sulci ( Figs 943 View FIGURES 943–946 , 955 View FIGURES 955–960 ) as, e.g., in Kalopolynema , petiole clearly attached to gs 1 ( Fig. 971 View FIGURES 970–973 ) as, e.g., in Acmopolynema , and propleura closed ( Figs 963, 965 View FIGURES 961–969 ) as, e.g., in Polynema (Doriclytus) .

Nearctic hosts. Unknown. Extralimital hosts are Hemiptera : Cicadellidae , Nabidae .
