Diagnosis
Males of C. alejandroi sp. nov. resembles those of C. bochalema sp. nov. (Fig. 3E–G) by a short and pointed cymbium that does not reach over twice the tibia length, but can be distinguished by a smaller tegulum, pear-shaped in lateral view (its size is less than the cymbium length), by a thicker embolus with rhomboidal tip (Fig. 2A–C), and by having a more pronounced dorsal tubercle on the palpal femur (Fig. 1E–G). Females can be distinguished from other known species of Caponina by having long, boomerang-shaped internal pair of sclerotized bars (psb) with elongated and thin boomerang-shaped anterolateral extensions (ae) fused from the base to the middle of the pair of sclerotized bars (Figs 1H–I, 2D–E).
Etymology
The specific name is a patronym in honor of Alejandro Sánchez Barreda, the youngest son of the first author.
