Brachiacantha robustihamata Nestor-Arriola & Toledo-Hernandez

Brachiacantha robustihamata Nestor-Arriola & Toledo-Hernández, 2017: 48.

Material examined.

Material listed in Nestor-Arriola and Toledo-Hernández (2017).

Diagnosis.

Length 4.5 mm, width 3.2 mm. Oval body. Three spots on each elytron, including an incomplete transversal band. Third ventrite with a small narrow cusp at each side of middle. Apical hook of the penis guide of the male genitalia large and rounded.

Distribution.

Guatemala and Costa Rica.

Discussion.

This species is very similar to B. bistripustulata and other species of the Brachiacantha dentipes group. The principal difference is the male genitalia with a robust curved hook and male ventral cusps longer than wide. The cusps in the third ventrite are similar to those of B. blaisdelli Nunenmacher, but the male genitalia of B. robustihamata are distinguished by the curved hook.
