Camponotus dalmasi Forel, 1899 ( Fig. 4 )

Identification: Belongs to theMyrmocladoecus subgenus, recognizable by its small propodeal spines. It can be confused with C. bidens and C. bispinosus , but both lack the conspicuous, hump-like elevation on the dorsopropodeum exhibited by C. dalmasi . Additionally, the pilosity on the dorsum of the gaster in C. dalmasi is less abundant than the other two species ( MacKay and MacKay, 2019).

Comments: The type series was collected in Colombia ( Kempf, 1972) and the species has also previously been reported from Venezuela ( MacKay and MacKay, 2019). This study presents the first report of this species in Ecuador and the western coast of South America, extending its distribution more than 1000 km of the southernmost known record. Previously, this species has been collected within termite nests alongside Crematogaster workers, in forested areas, urban areas, and among leaf litter ( MacKay and MacKay, 2019).
