Aphiochaeta is a genus of flies within the family Phoridae. Historically, it has been treated as a subgenus of the large and diverse genus Megaselia[2]. Members of this group are known for their varied ecological roles, including some species that act as specialized predators or parasitoids of other arthropods. For example, Megaselia (Aphiochaeta) araneivora has been documented as an egg predator of the orb-web spider Argiope aemura in Japan[3].
While specific morphological traits vary across the genus, studies of species such as M. araneivora highlight features common to this group, including markedly enlarged male labella, a swollen basal half of the first costal sector, and abdominal terga with dark markings[3]. Adult specimens are typically small, with features such as minutely haired compound eyes and globose third antennal segments[3]. The wings are often pale yellow to yellow in coloration[3].
