Diagnosis

This species can be recognized by this combination of features: pronotum and mesoscutum black, and metapleuron three-sided with the dorsal margin evenly down-curved. It is quite similar to S. cortesi but it can be differentiated by the ventrally tawny metafemur (vs entirely black) and tergite II tawny (vs black centrally and laterally yellow).

Etymology

The specific epithet ‘muqui’ is in reference to the mythological creature from the central Andes, that is believed to be a miner. It is treated as a noun in apposition.

Remarks

Seticornuta muqui sp. nov. occurs in Puna grasslands. It is the first species of Seticornuta to be found in Peru and is the species found at the highest elevation ( Fig. 11B View Fig ). The individual described here was captured in areas where Las Bambas copper mine has a restoration program for the endemic shrub Nototriche armeriifolia A.W. Hill ( Malvaceae Juss. ); this area was surveyed three times a year (2017– 2021) with a protocol that included pan traps, Malaise traps and pitfall traps. During this time only the one specimen of S. muqui sp. nov. was collected, suggesting that this species occurs at a low density.
