Acanthostichus lattkei

Collected in soil below leaf litter in a tropical forest.

Identification
Mackay (1996) - This species is closely related to the others in the complex, but is easily distinguished by the elongate antennal scapes, the absence of carinae on the sides of the petiole, and longitudinal striations on the dorsal surface of petiole. It lacks the strongly excised medial border of the clypeus of Acanthostichus bentoni and often has a tooth in the middle of the anterior border of clypeus.
