Trachysphyrus show different but equally consistent patterns of sea- 
sonal occurrence. 
In this species and the closely related T. viridis (Brulle) the 
second gastric tergite is mat and delicately granular. In all other 
Coastal Desert Imperialis Group Trachysphyrus the gastric terga 
are smooth and polished. Trachysphyrus cleonis differs from T. 
viridis by its sparsely punctate mesopleuron, wholly dark flagellum, 
and gold-stained thoracic pleura and propodeum.

This Trachysphyrus long has been known as T. kinbergi 
(Holmgren). However, recent examination of Brulle’s holotype 
confirms that viridis is the senior available name for the species 
(Porter 1975: 169) 
The only Coastal Desert record for T. viridis is of a single female 
taken at Arequipa, Peru (Porter 1967: 308). Otherwise, T. viridis 
ranges over most of southern South America from Lake Titicaca to 
the Straight of Magellan, but avoids Chile except at a few localities 
in the south where Patagonian Desert habitats intrude westward 
from Argentina. The species prefers semiarid to arid localities 
between sealevel and 3000 m, being especially characteristic of the 
Argentine Prepuna, Subandean Desert, Sierras de Cordoba, Chaco, 
Pampa, and Patagonian Desert. 
In accordance with its wide altitudinal and latitudinal range, T. 
viridis varies strikingly in phaenology from population to popula- 
tion. In the south or at high altitudes (1-3000 m), it generally is 
active during the warmer months of November to April. In the 
scorchingly subtropical Chaco Thorn Scrub (e.g., at Las Termas De 
Rio Hondo in Santiago del Estero, Argentina), adults emerge 
mainly during the mild weather of late May to early August.
