Emended diagnosis.

Males of P. elicioi differ from those of other Paratropis species by the morphology of the palpal bulb with very long and straight embolus (Figure 2E, F). Females can be distinguished by the morphology of spermathecal receptacles with long neck, longitudinal dorsal fold and numerous apical lobes (Figure 2H).

Remarks.

The examination of new material from Colombia and Ecuador allowed us to infer that both the diagnosis and the descriptions of the two sexes of P. elicioi were inaccurate ( Dupérré 2015). Below we present an emended description.

Distribution.

South of Colombia and north of Ecuador, on the Western Andean montane forest, between 500-1700 m altitudes. In Colombia it’s distributed on Nariño Department (Barbacoas, Reserva Natural Río Ñambí) and Ecuador distributed on Cotopaxi Province (Otonga Biological Reserve) and Pichincha Province (Santo Domingo; Nanegalito; Las Tolas) (Figure 10).
