ABSTRACT: Mazar Barnett & Buzzetti (2014) described a new species, Cichlocolaptes mazarbarnetti, from the Atlantic forests of northeastern Brazil. The holotype of the new species is a female that shows remarkable similarities with the sympatric Philydor novaesi. Here I analyze eight morphometric variables to assess phenotypic similarities among specimens of Philydor novaesi, Cichlocolaptes mazarbarnetti and other species in these two genera. The holotype of C. mazarbarnetti diﬀers from Philydor novaesi and falls in a region of the morphometric space occupied by specimens of Cichlocolaptes leucophrus. Therefore, morphometric data is consistent with other morphological, behavioral, and vocal data that suggest the existence of a new species Cichlocolaptes in the northern Atlantic forest. KEYWORDS: Cichlocolaptes mazarbarnetti, Philydor novaesi, Furnariidae, measurements, taxonomy. INTRODUCTION originally identiﬁed as P. novaesi is an exemplar of the new foliage-gleaner; diagnostic characters include a larger The avifauna of the northern stretch of the Atlantic body size, a longer beak, absence of buﬀy orbital feathers, Forest is one of the least known, yet most endangered on and rounded tail feather tips. Although Mazar Barnett & Buzzetti (2014) measured and discussed some biometric Earth. Habitat destruction has outpaced ornithological research and conducting research on some species today data, comparisons were limited to single variables is diﬃcult because of their scarcity and vulnerability. The and few species. As part of a large-scale morphometric inventory of the taxonomic composition of this avifauna analysis of the Furnariidae (Claramunt 2010; Claramunt is incomplete, as demonstrated by continuous discoveries et al. 2013), I examined and measured all specimens identiﬁed as P. novaesi at the Museu Nacional, including of new species in the last decades (e.g. Teixeira 1987; Teixeira & Gonzaga 1983, Silva et al. 2002). One such the holotypes of P. novaesi and C. mazarbarnetti.

The species is considered critically endangered (BirdLife International 2013). In a surprising turn of events, Mazar Barnett & Buzzetti (2014) Measurements were taken with a Mitutoyo Digimatic described yet another new foliage-gleaner from Murici, Point Caliper (resolution: 0.01 mm) with an output interface. Variables were the same as in previous Cichlocolaptes mazarbarnetti, based on ﬁeld observations morphometric studies of the Furnariidae (Claramunt and examination of museum specimens. The new species is extremely similar to P. novaesi in plumage pattern and et al. 2010; Claramunt et al. 2013). Here, I analyzed color but its behavior and vocalizations resemble those of only two variables from each body region because some Cichlocolaptes leucophrus. In particular, like C. leucophrus, measurements were highly correlated in foliage-gleaners: 1) wing length; 2) wing length to the ﬁrst secondary the new species shows a preference for foraging on feather; 3) tail length to central rectrices; 4) tail length to bromeliads. Upon examination of specimens identiﬁed as P. novaesi at the Museu Nacional in Rio de Janeiro, Mazar the most external rectrix; 5) bill length from the anterior Barnett & Buzzetti (2014) concluded that one specimen border of the nostril to the tip of the bill; 6) bill width at Morphometric insights into the existence of a new species of Cichlocolaptes in northeastern Brazil Santiago Claramunt the level of the anterior border of the nostrils; 7) tarsus Cichlocolaptes examined.

P. novaesi is larger than other species length axis. Again, female 34530 is closer to Cichlocolaptes of Philydor. Whereas males are relatively uniform (small and Pseudocolaptes rather than to other specimens of P. standard deviations), females previously assigned to P. novaesi and specimens of Philydor in general. novaesi (including the holotype of C. mazarbarnetti) are unusually heterogeneous, particularly in wing, bill, and tarsus length (Table 1). Female 33873 is about DISCUSSION 90% smaller than males’ averages in wing, tail, and feet variables.

Another with Cichlocolaptes are just a coincidence. This hypothesis possibility is that 34531 represents a young male P. novaesi is diﬃcult to test since, in principle, it does not predict and its small testicle was mistaken for a small, smooth a particular pattern of variation or position in the ovary. In any case, because of its young age, it is safer to morphospace in relation to other individuals or species. set this specimen aside for taxonomic considerations.
