FIGURE 5. A in A new species of manakin (Aves: Pipridae; Machaeropterus) from Peru with a taxonomic reassessment of the Striped Manakin (M. regulus) complex
FIGURE 5. A comparison of the shapes of the outer two primaries of adult male Machaeropterus r. regulus (A, AMNH 493126) and M. r. striolatus (B, LSUMZ uncataloged, GFS 465). The attenuated shape of these remiges in M. r. regulus is unique within the Striped Manakin complex; all other members share the wing shape exhibited here by M. r. striolatus.
FIGURE 4. A in A new species of manakin (Aves: Pipridae; Machaeropterus) from Peru with a taxonomic reassessment of the Striped Manakin (M. regulus) complex
FIGURE 4. A comparison of "advertising songs" of some taxa in the Machaeropterus regulus complex. A) M. eckelberryi (PERU: Loreto dept.; ca 77 km WNW Contamana, ca. 1000m. 12 July 1996. D. F. Lane, XC170145). B) M. eckelberryi (PERU: San Martín dept.; Morro de Calzada, ca. 1000m. 29 July 2005. D. F. Lane, XC170143). C) M. regulus striolatus (PERU: Loreto dept.; Jeberos, ca. 350m. 15 June 2001. D. F. Lane, XC170138). D) M. r. striolatus (PERU: Loreto dept.; Oran, ca 200m. 24 July 2013. D. F. Lane, XC170139). E) M. r. aureopectus (VENEZUELA: Bolivar state; El Pauji. 4 December 2010. A. Renaudier, XC66415). F) M. r. antioquiae (COLOMBIA: Santander dept.; Serranía de la Quinchas, RNA El Paujíl. F. Lambert, XC16781). G) M. r. regulus (BRAZIL: Rio de Janeiro; Reserva Ecológica de Guapiaçu. J. Minns, XC82253). Notice the light flat lines (around 1kHz and 3 kHz) "underscoring" the notes of the songs in figures C-G, but lacking in A and B. Also note that the song of M. r. antioquiae (F) is very similar in structure to those of M. r. striolatus (C, D), but the spacing between the two main notes is longer. The dark band running above the loudest fundamental frequencies of the notes in C and D is insect noise. "XC####" refers to recordings available at www.xeno-canto.org/####.
FIGURE 3 in A new species of manakin (Aves: Pipridae; Machaeropterus) from Peru with a taxonomic reassessment of the Striped Manakin (M. regulus) complex
FIGURE 3. Principal components analysis (PCA) of morphometrics of specimens of the Machaeropterus regulus complex (see also Table 1). See "Specimens examined" for list of specimens measured. Vector loadings show which measurements had the strongest effect on the plot analysis.
FIGURE 2 in A new species of manakin (Aves: Pipridae; Machaeropterus) from Peru with a taxonomic reassessment of the Striped Manakin (M. regulus) complex
FIGURE 2. Comparison of ventral and dorsal plumage of some taxa in the Machaeropterus regulus complex. Males are on left, females on right, except in the case of M. regulus, in which the male is above and the female below. Specimens exhibited (male, female): M. eckelberryi (MUSM 17725 [holotype], LSUMZ 161896); M. regulus aureopectus (FMNH 344155, 344154); M. r. striolatus (LSUMZ 115836, 110617); M. r. regulus (AMNH 43053, 493115).
FIGURE 1 in A new species of manakin (Aves: Pipridae; Machaeropterus) from Peru with a taxonomic reassessment of the Striped Manakin (M. regulus) complex
FIGURE 1. Map of distribution of Machaeropterus eckelberryi (inset map at lower right: black squares, star representing type locality, see "Distribution" for localities) with selected localities of M. r. striolatus from western Amazonia (black circles, LSUMZ specimens and XC170139), and M. r. aureopectus (white squares, from Phelps Collection and FMNH specimens, Hilty 2002, and XC66415) from the tepuis. Single localities are provided for M. r. antioquiae (white circle, XC16781), and M. r. regulus (continental map in lower left: black triangle, XC82253). Localities labeled with a number-letter code coincide with the letters of the recordings featured in Figure 4. Base map adapted from relief layer available at www.maps-for-free.com.
