( Figure 6 View Figure 6 (a–f))

Aegidinus cornutus Colby, 2009: 18

= Aegidinus unicus Colby, 2009: 37 , syn. nov.

Type locality. Brazil, Mato Grosso, Sinop.

Type material examined

Aegidinus cornutus : Holotype. Male at CMN labelled ‘SINOP 12°31ʹ S, 55°37ʹ W BR 163 km 500 a 600 Mato Grosso, BRASIL 350 m IX.1974 Alvarenga & Roppa col./Coleção M. Alvarenga/H. & A. HOWDEN COLLECTION ex. A. Martinez coll./ Aegidinus cornutus Colby HOLOTYPE ’.

Paratype. Male at CMN labelled ‘Oct. 976 BRASIL Minas Gerais Sinópolis Alvarenga – leg. Coll. Martinez /H. & A. HOWDEN COLLECTION ex. A. Martinez coll./ Aegidinus cornutus Colby PARATYPE ’.

Additional material examined

BRAZIL. Mato Grosso: Sinop, 12°31ʹ S, 55°37ʹ W, BR 163 km 500–600, 350 m, September 1974, Alvarenga, Roppa leg., two males and one female ( CEMT). Pará: Redençao, Pinkaiti – Aik , October 1999, P.Y. Scheffler leg., 18 males and nine females ( CEMT); Redençao, Pinkaiti – Aik , FIT, 2 November 1998, P.Y. Scheffler leg., one male ( CEMT).

Diagnosis

Aegidinus cornutus can be easily distinguished by the parameres not separated into dorsomedial and ventrolateral lobes ( Figure 6 View Figure 6 (c – e)). External female genitalia as in Figure 6 View Figure 6 (f).

Remarks

Aegidinus cornutus and Ae. unicus were both described from Sinop, Mato Grosso, Brazil, from a male and a female, respectively. Additional specimens of both sexes with the same locality labels as the holotype and a rather long series of both sexes from Redençao ( Figure 6 View Figure 6 (a,b)) show that the the two names belong to the same species. Therefore, a new synonymy is here proposed.

The label of the paratype of Ae. cornutus is wrong. There is no locality ‘ Sinópolis ’ in Minas Gerais, and Sinop has been probably misinterpreted as an abbreviation; if in the original data the state was noted as MGr or MG, it could be confused with Minas Gerais (instead of Mato Grosso). M. Alvarenga went to Sinop (Mato Grosso), then a just founded town, more than once in the 1970s and he was proud of his extensive collecting done there (personal comments to FZVM on several occasions, 1992 – 2008).
