A new sawfly (Hymenoptera: Pergidae: Acordulecerinae) feeding on guava, Psidium guajava l. (Myrtaceae), in Costa Rica. Proceedings of the Entomological Society of Washington. 107:214-217 Interpretive Summary: The caterpillar-like larvae of sawflies are economically important pests in agricultural crops, forests, and ornamental plantings. An undescribed species was discovered in Costa Rica feeding on leaves of guava, an important agricultural commodity in that country. The new species is described, illustrated, and distinguished from related species. Documentation of this pest will be useful to scientists involved in control of plant-feeding insects, producers of guava, and U. S. action agencies such as APHIS, whose goal is the detection and exclusion of invasive species from the United States. Technical Abstract: Sutwanus guajavae, n. sp., from Costa Rica is described and illustrated. Adults were reared from larvae feeding on Psidium guajava L. (Myrtaceae). A diagnosis is provided for distinguishing the new species from S. nigriceps (Cameron), the only other species in the genus. |
