Types and biological notes of the eastern North American sawflies of Pontania Costa and Phyllocolpa Benson (Hymenoptera : Tenthredinidae) described by Marlatt, Dyar, and Rohwer
Proceedings of the Entomological Society of Washington 101 (2), 359-371
Abstract: The taxonomic placement of 18 sawfly species assigned to Pontania and Phyllocolpa or described under Pontania from eastern North America by Marlatt, Dyar, and Rohwer are discussed. The authorship of Pteronus carpini, Pontania consors, and P. borealis attributed to Marlatt is changed to Dyar. The following eight species from eastern North America belong to Pontania (Eupontania): P. (E.) s-desmodioides (Walsh) (= Pontania borealis Dyar 1898, n. syn.); P. (E.) s-pisum (Walsh); P. (E.) s-pomum (Walsh); P. (E.) gracilis Marlatt; P. (E.) rugulosa Marlatt; P. (E.) petiolaridis Rohwer; P. (E.) consors Dyar; and P. (E.) lucidae Rohwer. Three species are included in the leaf-rolling crassispina group of the subgenus Pontania: P. (P.) pumila Rohwer; P. (P.) populi Marlatt; and P. (P.) terminalis Marlatt. Five species are included in the genus Phyllocolpa: P. nigrita (Marlatt); P. pectoralis (Marlatt); P. robusta (Marlatt); P. leavitti (Rohwer); and P. crassicornis (Rohwer), n. comb. Pontania acuminata Marlatt is transferred to Nematus, n. comb. Lectotypes are designated for seven species. The Salix and Populus-host plants are given and associated galls are, illustrated.
