Genus Paranaphoidea Girault ( Figs. 205–212 )

Paranaphoidea Girault, 1913 [165]: 115. Type species: Paranaphoidea egregia Girault , by original designation. Idiocentrus Gahan, 1927: 35 . Type species: Idiocentrus mirus Gahan , by original designation. Syn. nov. (subgenus of

Paranaphoidea ).

Diagnosis. Paranaphoidea belongs to the Anagrus group of genera. It is distinguished from other genera in the group as follows: clava 2- ( Fig. 205 ) or 3-segmented; back of head with a distinct, curved groove extending from dorsal margin of foramen to ventral margin of eye; subantennal grooves present and extending almost to mouth margin; posterior scutellum much longer than anterior scutellum and divided by a median longitudinal sulcus ( Fig. 212 ); mesophragma narrowly but distinctly notched apically ( Fig. 212 ); hind wing usually extremely wide ( Fig. 206 ); protibial spur with inner margin comblike ( Fig. 209 ), midtiblal spur long and also comblike ( Fig. 210 ). Hind leg as in Fig. 211 . Male antenna as in Fig. 207 and genitalia as in Fig. 208 .

One of us (JH) compared specimens of Idiocentrus mirus Gahan from New Zealand with Paranaphoidea elongata and a species close to or the same as P. egregia . Most features of these three species are the same or very similar. The notable differences are that females of mirus have a 3-segmented clava (2-segmented in described Australian species), the apex of the mesophagma is barely sinuate (distinctly notched in described Australian species), and males have the apical flagellar segment distinctly separated from the penultimate segment, similar to the previous segments (broadly joined in the Australian species). Noyes & Valentine (1989) suggested that the two genera might be synonymous and we agree. However, the differences noted here are considered to be sufficient to retain Idiocentrus as a separate subgenus within Paranaphoidea . The hosts are quite different, apparently Cicadidae for Idiocentrus ( Gahan 1927) and Cicadellidae (Eurymelinae) for the only species of Paranaphoidea with a host record, Eurymeloides punctata (Signoret) . At least one, undescribed species of Paranaphoidea (Idiocentrus) occurs in Australia. All the species listed below belong to the nominate subgenus.
