There are a lot of species of wasp. Thanks to Paul Marsh, Alexander Wild and James Whitfield of the University of Illinois, today we know about 280 more species of wasp than we used to. You may be surprised to hear how the scientists found them and how they named them.
Although all these new species originate in Costa Rica, the researchers didn’t have to travel to South America to collect them. The wasps all came from museum collections around the world, mostly from the University of Wyoming. I should point out that 277 of the wasp species were new to science. Yes, nearly 300 types of wasps previously unknown to science were languishing in museum drawers until someone had the inclination to pull them out and examine them a little more closely. Makes you wonder what else is in those drawers, doesn’t it?
At least these wasps finally got their thorough examination. The scientists used still and video cameras, stereomicroscopes and a scanning electron microscope to examine every part of them. Based on their morphology, they were able to classify the wasps within the genus Heterospilus.
And of course, there's H. wildi:
ZooKeys DOI: 10.3897/zookeys.347.6002.
Named for Alex Wild, whose head is as bald and shining as this species, in recognition of his work on the molecular analyses and imaging of the species in this study.
