Bertawolia Blocker

Bertawolia Blocker, 1979: 63 . Type-species: Bertawolia rhebala Blocker, 1979: 63 .

Diagnosis. (1) Head narrower than pronotum; (2) forewings with vein separating appendix and first apical cell evanescent apically, appendix and first apical cell membranous; (3) pygofer without distinct hooks; (4) pygofer, in ventral view, with numerous short setae at apex; (5) subgenital plates narrowly separated at base, *widely divergent distally, overlapping pygofer laterally; (6) connective U-shaped, bent into right angle at point of articulation with styles; (7) *style with apex foot-shaped (expanded apically); (8) *aedeagus expanded laterally, in posterior view.

Remarks. Features marked with an asterisk (*) were added and are present in all species. The following features were removed from the original diagnosis of Blocker (1979): (1) “pygofer with ventral margin expanded at middle third and apical third with excavation between, with apical margin acute at about mid-length”; in the new species the ventral margin of the pygofer lacks a deep excavation and the apex lacks an apical acute projection as in B. rhebala ; (2) “pygofer with heavily sclerotized area along ventral margin”; absent in the two new species; (3) “subgenital plate widened and triangular apically with inconspicuous “hook-like” area at base”; in the new species the apex of the subgenital plate is rounded, in B. lata sp. nov. the subgenital plate is not as wide as in B. rhelala and B. grazielia sp. nov.; the “inconspicuous hook-like area at base” mentioned by Blocker (1979) (Fig. 168: 65) (which presumably is the apodeme of the subgenital plate), is variable in size, and may be smaller, as in B. grazielia sp. nov. in comparison to B. rhelala , or strongly developed and directed dorsally as in B. lata sp. nov.
