Medionops luiscarlosi View in CoL sp. nov.

Figs 4 View Fig , 6 View Fig , 7D View Fig


Males resemble those of M. santarosa sp. nov. in having a similar copulatory bulb shape, but can be distinguished by the embolus length more than 3 × the maximum tegular width, with pointed tip ( Figs 4E–F View Fig , 7D View Fig ) (shorter, with truncated tip in M. santarosa sp. nov., Figs 5C–D View Fig , 7E View Fig ). Females are distinguished from those of all other species by the flat median concavity on the receptaculum ( Fig. 4H View Fig ).


The specific name is a patronym in honor of Luis Carlos Gutierrez, an unforgettable professor from the Universidad del Atlántico in Colombia who passed away in 2021.
