Eastern gorilla
Grauer's gorillas and mountain gorillas were previously thought to be two of the three subspecies of one single species, the gorilla ("Gorilla gorilla"). However, genetic research has shown that the two eastern subspecies are far more closely related than the western subspecies: the western lowland gorilla ("G. gorilla gorilla"), which justified the separate classification. The two eastern subspecies are now classified as "G. beringei".
Odonata
The largest living odonate is the giant Central American helicopter damselfly "Megaloprepus coerulatus" (Zygoptera: Pseudostigmatidae) with a wing span of 191 mm. The heaviest living odonates are "Tetracanthagyna plagiata" (Anisoptera: Aeshnidae) with a wing span of 165 mm, and "Petalura ingentissima" (Anisoptera: Petaluridae) with a body length of 117 mm (some sources 125 mm) and wing span of 160 mm. The longest extant odonate is the Neotropical helicopter damselfly "Mecistogaster linearis" (Zygoptera: Pseudostigmatidae) with a body length of 135 mm. Sometimes the giant Hawaiian darner "Anax strenuus" (Anisoptera: Aeshnidae) is claimed to be the largest living odonate with an alleged wing span of 190 mm, but this seems to be rather a myth as only 152 mm are scientifically documented.
