Oxynopterus mucronatus, sometimes known as the giant click beetle, is a species of click beetle from tropical Southeast Asia. Their larvae are specialized predators of termites. ^[1]

Taxonomy

Oxynopterus mucronatus was originally described by the French entomologist Guillaume-Antoine Olivier in 1792 as Elater mucronatus. The type specimen was obtained from the collection of William V, Prince of Orange. ^{[2] [3]} It became the type species of the genus Oxynopterus , established by the English naturalist Frederick William Hope in 1842. O. mucronatus is classified under the tribe Oxynopterini, in the click beetle family Elateridae. ^{[4] [5]}

The generic name Oxynopterus means "sharp-wing" in ancient Greek; while the specific name mucronatus is Latin for "pointed". Both refer to the sharp, pointed tips of the elytra. ^[6]

Description

Oxynopterus mucronatus, like other members of the genus Oxynopterus , are among the largest of the click beetles. ^{[7] [8]} The males have distinctive feather-like antennae, with long flat lamellae extending from the antenna segments. The females in contrast, have thin toothed antennae and are larger than the males. The prothorax is shield-shaped, with sharply pointed posteriolateral tips. The elytra are long and smooth, tapering to a sharp point. The claws are simple, without bristles (setae), pads, or lobes on the tarsal segments. They are predominantly reddish-brown in life. ^{[4] [6]}

Ecology

The larvae of O. mucronatus are specialized predators of termites of the genus Neotermes . ^{[1] [4] [9]}

Uses

Dried O. mucronatus is regarded as a traditional aphrodisiac in Javanese culture. ^[10] They are also popular among insect collectors due to their large sizes. ^[8]
