MYMAR Curtis, 1829

( Figs 593–622 )

Mymar Curtis, 1829: 112 . Type species: Mymar pulchellus Curtis, 1829 , by designation under the Plenary Powers of the International Commission on Zoological Nomenclature, 1965: 82 (Opinion 729).

Pterolinononyktera Maláč, 1943: 51 . Type species: Pterolinononyktera obenbergeri Maláč, 1943 , by original designation. Synonymy by Annecke & Doutt, 1961c: 26.

Diagnosis. Body length 560–1075 μm. Face with toruli abutting transverse trabecula ( Figs 594 , 605 ); antenna with scape narrower medially than apically and fu 2 longer than following segments combined ( Fig. 598 ); fore wing spatulate, without membrane for basal 0.6 of its length ( Figs 593 , 601 ); hind wing filamentous, without membrane and either extremely short ( Fig. 593 ) or longer and with a long apical seta ( Fig. 601 ).

Discussion. Among the nine other Nearctic genera of the Polynema group ( Acmopolynema , Caraphractus , Cnecomymar , Eustochus , Kalopolynema , Neomymar , Palaeoneura , Polynema , Stephanodes ), Mymar is most similar to Neomymar . Both have the toruli abutting the transverse trabecula, unlike the other genera, which have the toruli well separated from it. The wings are also more similar to each other than to other genera of the group; in both genera the fore wing is narrow for at least half its length before widening suddenly towards the apex.

Nearctic hosts. Unknown. Extralimital hosts are Hemiptera : Cicadellidae and Delphacidae ( Triapitsyn & Berezovskiy 2001) .
