Camponotus striatus

Three minor workers taken by Dr. Skwarra at Camaron, Vera Cruz, in spines of Acacia sphaerocephala (Wheeler 1934). Gillette et al. (2015) in a Chaipas, Mexico field study of twig-nesting ants in coffee plants found C. striatus nesting on plants between 650-900 m in elevation.

Identification
Workers possess a very depressed metanotal suture, a strong, dotted, and opaque sculpture on the sides of the head, and the sides of the pronotum are finely sculptured with smooth sections (Mackay & Mackay 2018).

Distribution based on Regional Taxon Lists
Neotropical Region: Colombia, Costa Rica, Honduras, Mexico, Panama.

Biology
De la Mora et al. (2016) found this species nesting in logs found in forests in the Soconusco region of Chiapas, Mexico.

Vanoye-Eligio et al. (2020) provide the following notes based on collections using Multilure-type traps from northeastern Mexico: Two Camponotus striatus workers and 1 major were recorded in Acacia sphaerocephala Schltdl. & Cham. (Fabaceae) and Coffea arabica L. (Rubiaceae) (Wheeler 1934; Gillette et al. 2015).
