Pycnoscelus striatus

Pycnoscelus striatus is a species of burrowing cockroach. It is closely related to the common plant pest Pycnoscelus surinamensis which has spread to tropical and subtropical regions across the world.

Description

Adult females are around in length, and have dark brown to black bodies with shiny paler brown wings which are variable in length. Males are around, i.e. often less than half the size of females, with comparatively longer wings completely covering the abdomen.
In the original description by Kirby, he noted the prosoma had a "front transversely striated", hence the species epithet.

Range

Pycnoscelus striatus originated in the Indomalayan region and is endemic to at least Indonesia, Malaysia, and the Philippines

Habitat

Pycnoscelus striatus is a burrowing cockroach, commonly digging in loose debris such as guano in caves, where they can reach a high density. It is found not to be displaced by the American cockroach.
