Aphaenogaster striativentris

Identification
A member of the Aphaenogaster gibbosa-group.

Distribution based on Regional Taxon Lists
Palaearctic Region: Iberian Peninsula, Spain, Spain.

Morphology
Castro et al. (2016) described a stridulatory structure in this species. They used SEM photographs to discern the details they reported.

The pars stridens is oval, but in this case it is wider than long, with a length of 0.09 mm and a width of 0.14 mm. The striation is thinner than the values obtained for Aphaenogaster senilis by Álvarez (2009), with a ridge average width of 0.90 μm. Pillars are more prominent than in A. senilis but, as in other species of Aphaenogaster, they are scarcely conspicuous and have a more diffuse sculpture.
