A new genus of oak gallwasps, Zapatella Pujade-Villar & Melika, gen. n., with a description of two new species from the Neotropics (Hymenoptera, Cynipidae, Cynipini)

A new genus of cynipid oak gallwasp, Zapatella Pujade-Villar & Melika, gen. n. (Hymenoptera: Cynipidae: Cynipini), with two new species, Zapatella grahami Pujade-Villar & Melika, sp. n. and Zapatella nievesaldreyi Melika & Pujade-Villar, sp. n., is described from the Neotropics. Zapatella grahami,known only from the sexual generation,induces galls in acorns of Quercus costaricensis and is currently known only from Costa Rica. Zapatella nievesaldreyi, known only from the asexual generation, induces inconspicuous galls in twigs of Quercus humboldtii, and is known only from Colombia. Diagnostic characters for both new species are given in detail. Five Nearctic species are transferred from Callirhytis to Zapatella: Zapatella cryptica (Weld), comb. n., Zapatella herberti (Weld), comb. n., Zapatella oblata (Weld), comb. n., Zapatella quercusmedullae (Ashmead), comb. n.,Zapatella quercusphellos (Osten Sacken), comb. n.

Taxonomic position of Hormaphis similibetulae Qiao & Zhang, 2004 (Hemiptera, Aphididae): molecular and biological evidences

The taxonomic position of Hormaphis similibetulae Qiao & Zhang, 2004 has been reexamined. The phylogenetic position of Hormaphis similibetulae was inferred by maximum parsimony, maximum likelihood and Bayesian analyses on the basis of partial nuclear elongation factor-1α and mitochondrial tRNA leucine/cytochrome oxidase II sequences. The results showed that this species fell into the clade of Hamamelistes species, occupying a basal position, and was clearly distinct from other Hormaphis species. A closer relationship between Hormaphis similibetulae and Hamamelistes species was also revealed by life cycle analysis. Therefore, we conclude that Hormaphis similibetulae should be transferred to the genus Hamamelistes as Hamamelistes similibetulae (Qiao & Zhang), comb. n.
