A new species of Haploberotha (Neuroptera: Berothidae) from mid-Cretaceous Burmese amber

Haploberotha carsteni sp. nov. (Neuroptera: Berothidae) is described from mid-Cretaceous Burmese amber. It has a very similar venation to H. persephone Engel and Grimaldi, 2008, but clearly differs by the male genitalia. The simplification of the venation (as found in H. carsteni sp. nov.) likely occurred independently many times in berothids during the Mesozoic. There are at least two character states in the male genitalia of some Cretaceous berothids, which are not found in extant taxa, i.e., the presence of extremely long gonocoxites 9, which extend far beyond the ectoprocts, and the long slender ventral process of T9+ectoproct.
