Medionops blades – Sánchez-Ruiz, Brescovit & Bonaldo 2020: 485 , fig. 19e ( ♂ ). Diagnosis Males resemble those of M. carolinae sp. nov. in having similar copulatory bulb shape, but can be distinguished by the straighter embolus tip and by the size of the tegulum, only ½ as long as the cymbium length ( Figs 1E–F , 7A ) (in M. carolinae sp. nov. , only ⅓ as long, Figs 2E–F , 7B ). Females of M. blades differ from those of M. carolinae sp. nov. by the wide, concave area below the genital opening ( Fig. 1G ) (in M. carolinae sp. nov. , narrower and triangular, Fig. 2G ).

Natural history The holotype was found in the Andean moorland complex of the eastern hills of Colombia ( Fig. 8A–B ) which is predominantly populated by plant species such as Espeletia grandiflora Humb. & Bonpl. and Cupressus sp. Description Male and female described by Sánchez-Ruiz & Brescovit (2017). Variation Males from the Boyacá department population ( Fig. 1A–B ) have the embolus tip somewhat more curved than those from Cundinamarca department (see images from types in Sánchez-Ruiz & Brescovit 2017: figs 2h, 6d). Females from the Boyacá population ( Fig. 1G ) have a narrower and more sclerotized area under the genital opening than those from the Cundinamarca population. Distribution Known from Cundinamarca and Boyacá in Colombia ( Fig. 6 ).
