This page represents the following TreeOfLife-200M taxonomic path.[1]
Members of the genus Apallates are small flies, typical of the family Chloropidae. Observations of specimens in the TreeOfLife-200M dataset reveal a characteristic body form with a well-defined head, thorax, and abdomen. The body is generally compact, with a robust thorax and a somewhat flattened or oval-shaped abdomen. The coloration often includes dark, sclerotized areas on the thorax and abdomen, which may contrast with lighter, yellowish or brownish regions on the head and legs. The wings are typically clear and membranous, with a reduced venation pattern characteristic of the family.[1]
The tibial organ in Apallates is a glandular structure located on the hind tibia. Externally, it is characterized by a dense patch of microtrichia, which may be situated within a small depression. This organ is present in both males and females and has not been linked to courtship or mating behaviors. Ultrastructural analysis reveals a class-1 glandular epithelium beneath the external microtrichia, which lacks a reservoir. The glandular cells contain numerous vacuolar spaces and vesicles, some of which appear to contain lipid droplets, suggesting a lipidic secretion. The presence of an associated nerve fiber suggests neurosecretory control.[2]
