Abstract

No studies have yet been conducted on the morphology and characteristics of the oropharyngeal cavity roof in various reptiles, particularly lizards and Gecko. This study aimed to provide a comprehensive analysis of the oropharyngeal cavity roof morphology and characteristics of T. annularis and H. vittatus. Both species have a palate of two parts: the rostral choanal vomeral part and the caudal part. The rostral palatine part is slightly longer due to a diastema. The palate is more triangular in H. vittatus than in T. annularis. The palatine papilla in H. vittatus is slightly elevated and separated from the incisive teeth by a transverse ridge, while in T. annularis; it is caudal to the incisive teeth. Both species have two cleft-like choana between the premaxillary and the maxillary bones. The caudal palatine part of T. annularis has two elevated tubercles, while H. vittatus carries 2–4 longitudinal ridges. T. annularis has three ridges: one median (which extends into the caudal part) and two transverse ridges, while H. vittatus had one transverse dental ridge and two mucosal folds. The rostral palatine part of T. annularis had glandular openings and taste pores with a taste process, while H. vittatus had numerous glandular openings only.

Tarentola annularis 和 Heremites vittatus 口咽腔顶的超微结构比较研究：特别是上颚与摄食习性的适应性

关于各种爬行动物，尤其是蜥蜴和壁虎的口咽腔顶的形态和特征，目前还没有相关的研究。本研究旨在全面分析环纹蜥和壁虎的口咽腔顶形态和特征。这两种蜥蜴的上腭均由两部分组成：喙腭部和尾腭部。喙腭部由于间隙而稍长。H. vittatus 的上腭比 T. annularis 的上腭更具三角形。H. vittatus 的腭乳头略微隆起，并通过一条横脊与门齿分开，而 T. annularis 的腭乳头则位于门齿的尾部。这两个物种的前下颌骨和上颌骨之间都有两个类似裂隙的choana。T. annularis 的腭尾部有两个隆起的小瘤，而 H. vittatus 则有 2-4 个纵脊。T. annularis 有三条脊：一条中脊（延伸到尾部）和两条横脊，而 H. vittatus 有一条横齿脊和两条粘膜皱褶。T.annularis的喙腭部有腺体开口和带味蕾突起的味孔，而H. vittatus只有许多腺体开口。

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
