Steganinae
Guides
Amiota
Amiota is a genus of small flies in the family Drosophilidae, established by Loew in 1862. The genus contains over 100 described species with a cosmopolitan distribution, though it exhibits particularly high diversity in East Asia. Southwestern China has been hypothesized as a possible center of origin and diversification. Some species serve as intermediate hosts and vectors for parasites, including Amiota okadai which transmits the zoonotic nematode Thelazia callipaeda.
Hyalistata
Hyalistata is a genus of small flies in the family Drosophilidae, described by Wheeler in 1960. It belongs to the subfamily Steganinae and tribe Gitonini, placing it within a group of drosophilids often associated with decomposing plant matter and fungal substrates. The genus is characterized by distinctive morphological features of the head and wing venation. Species within Hyalistata are poorly known and rarely encountered in general collections.
Leucophenga
Leucophenga is a large genus of fruit flies in the family Drosophilidae, comprising at least 240 described species. The genus was established by Mik in 1886 and is classified within the subfamily Steganinae. Species occur across multiple continents with documented diversity in India, northern Europe, and other regions. The genus has received taxonomic attention, including recent species descriptions from northern India.
Leucophenga maculosa
Leucophenga maculosa is a small fruit fly in the family Drosophilidae, originally described as Drosophila maculosa by Coquillett in 1895. The species belongs to the subfamily Steganinae and is part of a genus characterized by distinctive spotted or patterned body markings. It has been documented in multiple regions including the eastern United States, Hawaii, and parts of Brazil.
Phortica
Phortica is a genus of small flies in the family Drosophilidae, subfamily Steganinae. Several species are medically significant as biological vectors of the zoonotic eyeworm Thelazia callipaeda, which causes ocular infections in humans, domestic animals, and wildlife. The genus includes at least five species in Europe and the Middle East, with P. variegata and P. okadai being the best-documented vectors. These flies exhibit unusual zoophilic feeding behaviors, including lachryphagy (tear-feeding) in adult males of some species. The genus has gained increasing attention due to climate-driven range shifts and expanding transmission of thelaziosis.
Phortica picta
Phortica picta is a species of vinegar fly in the family Drosophilidae, described by Coquillett in 1904. It belongs to the subfamily Steganinae, a group characterized by distinctive morphological features including elongated mouthparts. The genus Phortica is known for species associated with specific ecological niches, though detailed biological information for P. picta specifically remains limited in published literature.
Phortica variegata
variegated fruit fly
Phortica variegata is a small vinegar fly in the family Drosophilidae, distinguished by its unusual zoophilic behavior. Unlike most drosophilids, adult males feed on the lacrimal secretions (tears) of mammals, including humans, dogs, foxes, and other carnivores. This lachryphagous behavior makes it the primary European vector of Thelazia callipaeda, a zoonotic eyeworm that causes ocular infections in mammals. The species is native to Europe and has been introduced to the United States, where it has demonstrated vector competence for the parasite. Climate change is projected to alter its distribution significantly, with suitable habitats shifting toward Mediterranean coastal regions while declining in central-southern-eastern European transitional areas.
Pseudiastata
Pseudiastata is a genus of vinegar flies in the family Drosophilidae, containing approximately 11 described species. The genus was established by Coquillett in 1908 and belongs to the subfamily Steganinae. At least one species has been documented as a predator of mealybugs in agricultural settings.
Pseudiastata nebulosa
Pseudiastata nebulosa is a small fruit fly species in the family Drosophilidae, first described by Coquillett in 1908. It belongs to the subfamily Steganinae, a group of drosophilid flies often associated with decaying organic matter and fungal substrates. The species is part of a genus whose members are poorly known biologically, with limited published information on their ecology or behavior.
Rhinoleucophenga americana
A species of fruit fly in the family Drosophilidae, originally described as Gitona americana by Patterson in 1943. The genus Rhinoleucophenga includes species associated with ant-plant mutualisms, though specific ecological details for R. americana remain undocumented. The species is rarely recorded, with minimal observational data available.
Rhinoleucophenga obesa
Rhinoleucophenga obesa is a species of fruit fly in the family Drosophilidae. Long misidentified in the Neotropics, it is now confirmed as endemic to the Nearctic region with type locality in Texas, USA. Brazilian specimens previously attributed to this species have been reassigned to sibling species R. cantareira and R. gigantea based on morphological and molecular evidence.
Stegana
vinegar flies
Stegana is a genus of vinegar flies (Drosophilidae) comprising at least 140 described species. The genus is characterized by high morphological conservatism, particularly in the subgenus Orthostegana, where evolutionary stasis has produced numerous cryptic species that are difficult to distinguish by external morphology alone. Species delimitation often requires integrative approaches combining molecular data (mitochondrial COI and ND2 genes) with detailed morphological analysis.
Stegana antigua
Stegana antigua is a species of small fly in the family Drosophilidae, subfamily Steganinae. It was described by Wheeler in 1960. The genus Stegana is part of the tribe Steganini within the subfamily Steganinae, a group of flies commonly known as vinegar flies or fruit flies, though distinct from the more widely known Drosophila melanogaster species group. Members of this subfamily are typically associated with decaying plant material and fungal substrates.
Stegana vittata
Stegana vittata is a species of fruit fly in the family Drosophilidae, placed in the subfamily Steganinae. The genus Stegana comprises small flies typically associated with decaying organic matter and fungal substrates. Beyond its taxonomic placement, specific biological details for this species remain poorly documented in accessible literature.
