QUICHUANA RIESELI SHANNON, 1927a: 5

We were unable to examine any material of this species. According to Shannon (1927a), the holotype is a female from a larva collected in a bromeliad with spiny leaves. The type locality was ‘Cerro de Aconquija, Tucumán, Argentina’ and was collected on 12.vii.1926 by M.A. Riesel, whose name is given to the species. Hull (1946) provided a translation of the original description, but omitted some key data. Shannon (1927a) stated that the holotype was in his collection, now at USNM, but Thompson et al. (1976) reported that the holotype was deposited in MACN, which we were unable to confirm, and no other material is known. Hull (1946) also did not study the holotype or key Q. rieseli .

Range

Argentina.

Taxonomic notes

According to the original description, Q. rieseli is a small to medium size species with an extensively pollinose face (presumably with a central shiny black stripe), tarsi darkened (more heavily towards the apex), groups of yellow hairs on tergum I, and with a large opaque triangular spot on tergum II centrally. The original description does not provide sufficient information to distinguish this species from similar species, and it is not further evaluated here, nor is there sufficient information to include it in the key.
