Scinax hayii (10.3897-zoologia.34.e20176) Figures 22–26

Description:

Figures 22–26; Light micrograph of the integument of S. hayii: (22) Dorsal region (Mallory´s trichrome staining); (23) Dorsal region (AB-method); (24) Ventrolateral region (HE-staining) (25) Ventral region (AB-method); (26) Ventral region (HE-staining). In the dorsal integument, exocrine glands are more frequent, mainly the serous glands (Ø). Melanophores (_) occur in the spongious dermis, even around the secretory portion of glands. Note clusters of apocrine glands with heterogeneous content (¬)in the spongious dermis of the ventrolateral integument. The EK-layer (Æ) is continuous in the dorsal integument, but absent in the ventral region. Slight cutaneous elevations (á) in the ventral integument are formed by the epidermis and the dermis, mainly the spongious dermis. They are separated by groves (). CD = compact dermis.
