FIGURE 3 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 3. Distribution of 60 calls of five species of Euparkerella (males) along the first and second axes of a Principal Component Analysis (PCA) generated from six acoustical variables. Note the five distinct clusters corresponding to five recognized species.
FIGURE 2 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 2. Distribution of 84 specimens of five species of Euparkerella (males and females) along the first and second axes of a Principal Component Analysis (PCA) generated from six morphometric variables.
FIGURE 9 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 9. Euparkerella robusta from Mimoso do Sul, ES, Brazil. (A) Oscillogram and (B) audiospectrogram of an advertisement call (ASEC 17693) without frequency modulation. (C) Oscillogram of two pulses of an advertisement call (ASEC 17687) which presents the second amplitude peak and de periodic amplitude modulation at the end of the pulses. (D) Oscillogram, (E) audiospectrogram and (F) power spectrum of an advertisement call (ASEC 17684) which illustrates frequency modulation at the end of the pulses. Note the low number of pulses and their long duration. Audiospectrograms and power spectrums with Window function Hann, amplitude logarithmic, window size 512 samples, overlap 99%.
FIGURE 8 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 8. Distribution of the species of Euparkerella. Euparkerella brasiliensis (circle); E. cryptica sp. nov. (white star); E. cochranae (triangle); E. robusta (pentagon); E. tridactyla (square). White symbols represent type localities; black symbols indicate the provenances of the specimens examined from zoological collections; symbols marked with a cross indicate the provenances of the acoustically recorded specimens. The type locality of E. brasiliensis is not precisely known (Izecksohn 1988) and therefore, not shown.
FIGURE 7 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 7. (A–C) Euparkerella cryptica sp. nov. from Silva Jardim, RJ, Brazil. (A) Oscillogram, (B) audiospectrogram (C) and power spectrum of an advertisement call (ASEC 17678). Note the long duration and the presence of pulse clusters. (D–F) Euparkerella tridactyla from Santa Maria de Jetibá, ES, Brazil. (D) Oscillogram, (E) audiospectrogram (F) and power spectrum of an advertisement call (ASEC 17704). Note the long duration and high number of pulses. Audiospectrograms and power spectrums with window function Hann, amplitude logarithmic, window size 256 (B, C) and 512 (E, F) samples, overlap 99%.
FIGURE 1 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)

FIGURE 6 in A fifth species of the genus Euparkerella (Griffths, 1959), the advertisement calls of E. robusta Izecksohn, 1988 and E. tridactyla Izecksohn, 1988, and a key for the Euparkerella species (Anura: Brachycephaloidea: Craugastoridae)
FIGURE 6. (A–E) Euparkerella cryptica sp. nov. from Silva Jardim, RJ, Brazil. (A) Ventral view of the left hand, holotype (ZUFRJ 13281). The arrow indicates the presence of digital pad and partially overlapped subarticular tubercle. (B) Ventral view of the left hand (MNRJ 85756). The arrow indicates the presence of a single digital pad. (C) Ventral view right hand (ZUFRJ 12851). The arrow indicates the presence of a digital pad and a subarticular tubercle. (D) Ventral view of the left foot (ZUFRJ 12645). The arrow and dashed line indicate the tip of the Toe V reaching near the middle of proximal subarticular tubercle of the Toe IV. (E) Ventral view of the right foot (ZUFRJ 12852). The arrow and dashed line indicate the tip of the Toe V extending beyond the proximal subarticular tubercle of the Toe IV. (F) Euparkerella tridactyla from Santa Teresa, ES, Brazil. Ventral view of the left hand (ZUFRJ 1928).
