Genus Cotylana Fennah, 1954

Cotylana Fennah, 1954: 463 . Type species: Lollius acutipennis Kirkaldy, 1906 (by original designation).

The genus Tylana Stål, 1861 was erected for species from the Mascarenes ( Mauritius) ( STÅL 1861, WILLIAMS 1982). The genus needs revision as already mentioned by WILLIAMS (1982). It is probably monotypical as its type species, Tylana cristata (Fabricius, 1803) , is very peculiar and differs from other species assigned to Tylana by the metope narrow between eyes, with no intermediate carinae and the coryphe with leaf-shaped lateral margins ( WILLIAMS 1982: Figs 1–3 ). Based on this feature of the coryphe Tylana may be closely related to Epitonga .

Our study of Issus lineolatus Walker, 1862 from Queensland in Australia, placed by DISTANT (1909) to the genus Tylana , shows that this species actually belongs to the genus Cotylana which was erected by FENNAH (1954) for another Australian species, Lollius acutipennis Kirkaldy, 1906 , and to which some species from New Caledonia were later added ( FENNAH 1969). Cotylana is distinguished within the tribe Tongini by a tricarinate metope ( Fig. 15 ) and wide fore wings with reticulate venation ( Fig. 14 ).
