Key to the New World species of Coiba Marsh (Hymenoptera: Braconidae: Doryctinae), including descriptions of two new species, new distribution records and a key to species. Proceedings of the Entomological Society of Washington. 111(1):183-198. Interpretive Summary: Parasitic wasps attack forest pests that cause billions of dollars of damage to forests annually. The parasitic wasps treated in this paper likely attack wood-boring beetle larvae, as one species was reared from wood-infesting insects and all belong to a group with species known to attack wood-boring beetle larvae. Increased knowledge of these wasps can help determine their impact as beneficial insects. This paper provides information on the identification, distribution, and biology of five species in the Western Hemisphere. Two species new to science are described, and new distribution records are given for two species. Host utilization is discussed for one species, and an identification key is provided for all species. This information will be useful to regulatory officials at ports, biocontrol workers, and pest managers contending with pest beetle larvae in wood. Technical Abstract: Coiba jeffersoni Kula, new species from the Nearctic Region and Coiba marshi Kula, new species from the Neotropical Region are described. A diagnosis is provided for both species, as is a key to the New World species of Coiba. Coiba jeffersoni likely attacks wood-boring beetle larvae, as label data indicate that specimens were reared from Carya ovata (Mill.) K. Koch (shagbark hickory), Juglans nigra L. (black walnut), and an undetermined species of Quercus L. (oak). The first record of Coiba dentatus Marsh in Brazil and Coiba woldai Marsh in Venezuela is reported. |
