Glyptocis

Glyptocis is a genus of weevils in the family Curculionidae, within the order Coleoptera. The genus is referenced in entomological catalogs and regional checklists as containing several described species, though the exact count can vary with taxonomic revisions and new descriptions.

Characters and biology are broadly consistent with many weevils. Members of Glyptocis are typically small to medium in size, with a compact to elongate body and a rostrum (snout) of varying length. The exoskeleton often shows fine sculpture or punctation, which can contribute to a textured appearance. As phytophagous insects, larvae commonly develop inside plant tissues such as seeds, stems, or other immobile plant parts, while adults feed on foliage, seeds, or flowers, depending on the species and host plant.

Taxonomy within Curculionidae has seen revisions affecting many genera, and Glyptocis has been treated as a valid genus in standard classifications. The placement at subfamily or tribal level has varied across sources as systematics of weevils have advanced. The genus comprises several described species, but the boundaries and numbers of species are subject to change with ongoing taxonomic work, and comprehensive species-level information remains incomplete for some lineages.

Distribution is generally described as Neotropical to subtropical, with records reported from parts of Central and South America and nearby regions. Habitat associations are typically linked to plant communities where host plants occur, including forested and semi-forested areas.

Glyptocis represents the diversity of weevils and their relationships with plants, illustrating the ongoing need for broader taxonomic and ecological studies to clarify species limits, host ranges, and distribution. See also: List of weevil genera.
