Predaceous midges of the genus Paryphoconus Enderlein are medium-sized to large (female wing lengths 1.5-7 mm) exclusively inhabiting the Neotropical region. It includes 40 species, of which the pupae of P. mayeri Wirth, P. flavidus (Johannsen) and P. oliveirai Lane, are only known, the first two are incompletely described. The purpose of this presentation is to fully describe the male pupa of Paryphoconus aemulus Macfie from material obtained during a recent survey of immatures in the Amazon river basin near Manaus, Brazil. The pupa of Paryphoconus aemulus was collected with pippete from macrophytes (Salvinia auriculata Aubl. Fam. Salviniaceae) in Ilha da Marchantaria (Município de Iranduba, Amazonas). Observations were made daily, until adult emergence. The pupa of P. aemulus is distinguished from P. oliveirai, a species also occurring in Manaus, by its smaller length (6.00 mm in P. oliveirai), the  ventrolateral setae (vl) represented by a pore (with a thin seta in P. oliveirai), all setae of pupa well visible and weaker than in P. oliveirai, the anterior margin of the operculum slightly curved (pointed in P. oliveirai) and the apicolateral processes with their apical 1/3 not pigmented. The pupa of P. mayeri is slightly larger (4.3 mm) than P. aemulus (3.70 mm), and exhibits 3 dorsolateral setae (dl) (2 in P. aemulus).
