Species Guides

Thysanoes is a of bark beetles in the Curculionidae, Scolytinae, containing approximately seven described . Species in this genus are phloeophagous, feeding on the inner bark of trees, and construct gallery systems for breeding. The genus has been documented with a monogynous mating system, where a single female initiates and maintains a gallery system.

Habitat

Inner bark (phloem) of trees; associated with woody plants in forested environments.

Distribution

Documented from Mexico; additional distribution records likely exist in North America given the presence of such as T. texanus and T. fimbricornis described by LeConte and Blackman.

Diet

Phloeophagous; feeds on inner bark (phloem tissue) of trees.

Life Cycle

Gallery-based breeding system; females initiate monogynous galleries (single female per gallery system) in bark. Larval development occurs within these galleries.

Behavior

Constructs breeding galleries in bark of trees; exhibits monogynous breeding system where one female establishes and maintains a gallery system.

Ecological Role

Primary colonizer of tree bark; contributes to decomposition of phloem tissue and nutrient cycling in forest . Associated with other scolytid and platypodid beetles in contexts.

Mating System

Thysanoes has been explicitly categorized as monogynous in comparative studies, contrasting with bigynous such as Scolytus propinquus where males maintain two females per gallery system.
