Taxonomy

edit

This species was described by François-Louis Laporte de Castelnau, a french naturalist in 1867. The type specimen is in the Genoa Museum, Italy.[2]

Description

edit

Mecodema crenicolle is a medium-large ground beetle with a length of 22–29 mm. As a member of the ducale group of Mecodema species, the pronotum carina is strongly crenulated and outer striae are coarsely punctured with star-shaped asetose punctures. These punctures are irregularly placed and deeper in the outer striae. A distinguishing character of M. crenicolle from its sister species, M. crenaticolle[3] is that the punctures in elytral stria 7 are larger than stria 8 and cannot be distinguished at the base of the elytra.[2]

Habitat and ecology

edit

M. crenicolle is a burrowing ground beetle that lives in native forests, pine plantations and pastures. Their elevational distribution ranges from lowland to mountainous forests.[4] Like all Mecodema species, M. crenicolle is flightless and a predator of other invertebrates.[4]

Distribution

edit

This species is only found in the in Marlborough, Nelson and the Brunner District in the South Island.[4][2] North Island specimens are all M. crenaticolle as per Seldon & Buckley (2019).
