巨大的青步甲 Huge Chlaenius

Largest Chlaenius I've ever seen. Body length 19mm. I think it is Chlaenius costiger / Haplochlaenius costiger.
Too many ground beetles recently!

Hi Littlelittle, Wow 19mm - that is a lot bigger than any Carabidae I have seen in Hong Kong.  

This spring on Lantau, hasn't been very good for Carabid beetles I have had seventeen species. Just in case you want to see some of the photographs, the species are:

Scarites sp
Craspedophorus mandarinus (Schaum.)
Stenolophus quinquepustulatus (Wiedermann 1827)
Drypta lineola Chaud  
Oodes sp.
Platymetopus flavilabris (Fabricius 1798)
Chlaenius junceus Andrewes 1923
Chlaenius hamifer  Chaudoir
Plus Lebia sp. x2 spp, Harpinae sp x 4 spp.and Carabidae sp x 3 sp.

Kind regards PAul

回覆 #1 littlelittle 的帖子 : Chlaenius costiger

Probably the same species Chlaenius costiger, this one is about 20mm found in Pat Heung in May 2014



I identified it as Trigonotoma lewisii and got the following comment :

Trig. lew. is similar in ribbed elytra and coulors, but markedly different in:
- wide head;
- legs stouter and black;
- elytra without fine hairs.
and belongs into another subgroup of Ground beetles than Chlaenius.
I assume, your beetle is C. (Haplochlaenius) costiger Chaudoir, 1856.
It is not C.(H.) flavofemoratus, recorded for Hongkong on reference site:
