小蛾科的单一性是由大量的突触性幼虫特征所支持的。尽管小蝌蚪具有独特性，但很少有研究关注其幼虫的发育。小蝌蚪幼虫的形态通常是根据标准表格描述的，这意味着蝌蚪整体发育的等效阶段的发育事件独立于物种特定的发育时间模式。在此，我们提供了基于外部形态学和野外数据的额外发育数据，以胃胃碱微水螅皮蝇幼虫生长。我们描述了幼虫发育过程中的内部形态变化（例如骨骼和软系统）。结果表明，某些变质作用的发生时间要早于目前的铀矿发育表。本研究提供了小水螅物种的基线信息，可以比较个体发育轨迹、影响幼虫体形的异时模式，以及幼虫形态对成年小水螅体形的作用。
The monophyly of Microhylidae is supported by an overwhelming accumulation of synapomorphic larval features. Despite the distinctiveness of the microhylid tadpole, few studies have focused on larval development. Microhylid larval morphology is usually described and based on standard tables that imply that developmental events at equivalent stages of overall tadpole development are independent from species-specific patterns of developmental timing. Herein, we present additional developmental data based on external morphology and field data on larval growth for the gastrophrynine microhylid Dermatonotus muelleri. We describe internal morphological variation (e.g., skeletal and soft systems) during larval development. The results indicate that the onset of some metamorphic changes occur earlier than those implied in current anuran developmental tables. This study provides baseline information for microhylid species that will allow comparisons of ontogenetic trajectories, heterochronic patterns influencing larval body plan, and the role of larval morphology on the adult microhylid body plan.
