Figure 4 in Anatomy, histology, and systematic implications of the head ornamentation in the males of four species of Limnonectes (Anura: Dicroglossidae)
Figure 4. Comparative overview of the histological structure of the caruncles in the four species of Limnonectes: A, Limnonectes dabanus; B, Limnonectes gyldenstolpei; C, Limnonectes macrognathus; D, Limnonectes plicatellus. Note that in spite of the fundamentally differing external morphology, the histology is virtually identical: a size-variable pad of connective tissue (ct) lies between the skin (sk) and the parietal bone (pb). Scale bars: 2 mm.
Figure 5 in Anatomy, histology, and systematic implications of the head ornamentation in the males of four species of Limnonectes (Anura: Dicroglossidae)
Figure 5. Details of the histological structure of the caruncle. A, dorsal portion of the caruncle parasagitally sectioned and showing the typically layered skin, with underlying connective tissue (ct). Abbreviations: ct, connective tissue; lc, lamina calcarea; sc, stratum corneum; sco, stratum compactum; sg, stratum germinativum; ss, stratum spongiosum. B, transverse section through the lateral margin showing the overall homogeneity of the caruncle. C, D, irregular osseous projections (op) of the parietal bone at the anterior margin of the caruncle. E, detail of dense connective tissue. F, cleavage within the connective tissue of a flap-like caruncle. G, detail of the connective tissue showing capillaries (arrowheads) of various dimensions and fat cells (fc). Limnonectes macrognathus is shown in (A), (D), and (E); L. gyldenstolpei is shown in (B), (F), and (G); L. dabanus is shown in (C). Scale bars: A, D, E, G, 100 μm; C, 200 μm; B, F, 500 μm.
Figure 3 in Anatomy, histology, and systematic implications of the head ornamentation in the males of four species of Limnonectes (Anura: Dicroglossidae)
Figure 3. Radiographs of the four species of Limnonectes examined in the present study in dorsal (top row), ventral (middle row), and lateral (bottom row) views. Note the translucent caruncle and the underlying osseous bulging of the parietal bone, most pronounced in Limnonectes dabanus (arrowhead). The arrows indicate the concave lateral curvature of the anterior ramus of the pterygoid bone. Only the dorsal images are to scale. Scale bar: 1 cm.

Note the flap-like caudad curve of the posterior margin of the caruncle (ca). Abbreviations: br, brain; ca, caruncle; to, tongue. Scale bar: 1 cm.

Ordination of the first and second (top left) and second and third (top right) principal components for L. acanthi (Palawan) and L. cf. acanthi (Mindoro), with scatterplot of DAPC results (bottom right) with inertia ellipses for emphasis. Yellow shades represent Mindoro clade individuals and blue shades represent Palawan clade individuals, while light tones represent females and dark tones represent males.
FIG. 1 in A New, Morphologically Cryptic Species of Fanged Frog, Genus Limnonectes (Amphibia: Anura: Dicroglossidae), from Mindoro Island, Central Philippines
FIG. 1. Maximum likelihood phylogenetic tree (left) and map of molecular sampling localities (right). Maximum likelihood tree generated in IQ-TREE (Minh et al., 2020). Support values on branches are UFBoot/SH-aLRT and outgroup terminals are L. finchi (1), L. parvus (2), L. palavanensis (3), L. leytensis (4), L. magnus (5), L. diuatus (6), L. visayanus (7), and L. macrocephalus (8). Sampling sites of Limnonectes acanthi on Palawan Island (blue) and samples of L. cf. acanthi from Mindoro and Semirara Islands (yellow) are plotted on islands (gray), surrounded by the 120-meter underwater bathymetric contour (pale yellow), approximating coastlines during the last glacial maximum. Branch length scale bar units ¼ substitutions/site. See Data Accessibility for tree file.
