status

sp. nov.

Mimicalges neopelmae   sp. nov.

Type host

Neopelma pallescens (Lafresnaye, 1853)   ( Pipridae   ), the Pale-bellied Tyrant-Manakin.

Type locality

Macaíba, Rio Grande do Norte, Brazil.

Type material

Male holotype ex Neopelma pallescens   , “Mata da Escola Agrícola de Jundiaí-UFRN” (5 ◦ 53 ′ S, 35 ◦ 23 ′ W), Macaíba, Rio Grande do Norte, Brazil, 20April 2012, col. H.M. Silva. Paratypes: 11 males and 11 females from the same locality, 19 June 2012, 1 male 10 June 2012, 1 female 20 June 2012. Holotype male, 9 male and 9 female paratypes at DZUnesp-RC; a pair of male and female paratypes in each of DZSJRP, BMOC and ZISP GoogleMaps   .

Diagnosis

The new species differs from M. pteronyssoides   by the relatively shorter length of aedeagus, not reaching the body terminus; in M. pteronyssoides   the aedeagus extends well beyond the body terminus, almost reaching the level of tarsus IV.
