Genus Ishiharella Dworakowska, 1970

Ishiharella Dworakowska, 1970 , Bulletin de l’ Academie Polonaise des Sciences. Serie des Sciences Biologique, 18 (11): 716.

Type species. Ishiharella polyphemus ( Matsumura, 1931)

Description. Body robust ( Figs 44, 46, 48, 50, 52 ). Crown broad, coronal suture absent, anterior margin rounded, with median black spot, posterior margin concave, midline shorter than interocular width ( Figs 44, 46, 48, 50, 52 ). Face broad, width across eyes nearly equal to length, frontoclypeus swollen ( Figs 45, 47, 49, 51, 53 ). Pronotum large, much longer and slightly wider than crown, with pair of sublateral curved markings; scutoscutellar sulcus distinct, not reaching lateral margin ( Figs 44, 46, 48, 50, 52 ). Forewing with RP and MP’ stalked, RP, MP’ and MP’’+CuA’ arise from m cell; hindwing with CuA unbranched.

Abdominal apodemes not greatly enlarged ( Figs 1 , 10 , 19 , 28 , 36 ). Pygofer lobe with outer margin infolded and forming slight process distally ( Figs 3, 4 , 12, 13 , 21, 22 , 30 , 38 , 39). Subgenital plate partly to completely fused, with row of sublateral macrosetae ( Figs 2 , 11 , 20 , 29 , 37 ). Paramere elongate, apex highly modified and variable interspecifically ( Figs 5, 6 , 14 , 23 , 31 , 40 ). Aedeagus shaft broad, structure complex, basally with long paired processes ( Figs 7, 8 , 15, 16 , 24, 25 , 32, 33 , 41, 42 ). Anal tube process well developed ( Figs 9 , 18 , 27 , 35 , 43 ).

Discussion. The genus Ishiharella Dworakowska resembles Dialecticopteryx Kirkaldy and Velu Ghauri in having the latero-posterior margin of the crown with a shallow concavity, the posterior margin of the pronotum with a black triangular-shaped mark, RP and MP’ of the forewing stalked, RP, MP’ and MP’’+CuA’ arising from m cell, and CuA of the hind wing unbranched ( Figs 44, 46, 48, 50, 52 ) and in the male genitalia by the aedeagal shaft with a very long process ( Figs 7, 8 , 15, 16 , 24, 25 , 32, 33 , 41, 42 ). It differs from both genera by the presence of a lateral black spot on the vertex and from Dialecticopteryx by the absence of a coronal suture ( Figs 44, 46, 48, 50, 52 ), the elongate, apically specialized paramere ( Figs 5, 6 , 14 , 23 , 31 , 40 ), and the aedeagus separated from the connective ( Figs 7, 8 , 15, 16 , 24, 25 , 32, 33 , 41, 42 ).

Distribution. China (Anhui, Hunan, Hubei, Guangdong, Guizhou, Shaanxi, Zejiang, Yunnan); Japan; Russia; Thailand.
