Mecodema chaiup is a large-bodied ground beetle species found in Mohi Bush Scenic Reserve, Hawke's Bay, New Zealand. A single specimen was found beneath a large log in 2008 by D.S. Seldon and C.P. Martin (who it is named after). Since then a number of intensive pitfall trap surveys of Mohi Bush have failed to collect further specimens.
Diagnosis
[edit]Mecodema chaiup is distinguished from other North Island Mecodema by:
- Narrow elytra (narrower than the pronotum at the widest point)
- Distinct asetose punctures in a confused pattern that are irregular in size and shape[1]
Description
[edit]Length 31 mm, pronotal width 8.5 mm, elytral width 6.5 mm. Colour of entire body matte black, except for the femur and tibiae which are dark reddish-brown.[2]
Natural History
[edit]Flightless and presumably a nocturnal predator of a range of ground invertebrates (e.g., spiders, carabids, worms), as are the other members of the genus.
