Anahita
Anahita is a genus of wandering spiders in the family Ctenidae, established by Karsch in 1879. The genus name derives from an Iranian goddess associated with waters and fertility. These spiders are part of the diverse tropical and subtropical spider fauna, with species distributed across parts of Asia and Africa. As ctenids, they possess characteristic eye arrangements and are active hunters rather than web-builders.
Pherhimius
Pherhimius is a genus of click beetles (Elateridae) established by Fleutiaux in 1942. The genus is part of the diverse elaterid fauna and is recognized as valid in current taxonomic databases. As a genus-level taxon, it contains multiple species distributed primarily in tropical and subtropical regions. The genus is documented in GBIF, NCBI, and iNaturalist with over 500 observations, indicating moderate field recognition.
Psychodidae
Moth flies, Drain flies, Sink flies, Filter flies, Sewer gnats, Sand flies
Psychodidae is a large family of true flies comprising over 2,600 described species worldwide, with highest diversity in humid tropical regions. Members exhibit distinctive short, hairy bodies and wings that create a moth-like appearance. The family encompasses two ecologically divergent groups: non-biting moth flies that inhabit moist, decaying organic matter and plumbing systems, and blood-feeding sand flies (subfamily Phlebotominae) that serve as disease vectors.
Sparassidae
Huntsman spiders, Giant crab spiders, Wood spiders
Sparassidae, commonly known as huntsman spiders or giant crab spiders, comprises a family of large, fast-moving araneomorph spiders distributed primarily in tropical and subtropical regions worldwide. Members are characterized by laterigrade legs—oriented horizontally to the body—that enable them to navigate narrow crevices and vertical surfaces with ease. The family includes both solitary and social species, with some genera exhibiting prolonged subsociality where females share retreats with multiple generations of offspring for extended periods. Several species are known to occasionally appear in temperate regions through human commerce, particularly in banana shipments.
