Blephariceridae: Classification and Distribution
Several investigations (e.g., Wood and Borkent 1989, Courtney 1991, Oosterbroek and Courtney 1995) have provided compelling evidence for monophyly of the superfamily Blephariceroidea (Deuterophlebiidae + Blephariceridae). Synapomorphies that help define this clade include features of the larva, pupa, and adult (details in Courtney 1991, Oosterbroek and Courtney 1995). Monophyly of the Blephariceridae is also well established and based largely on features of the larva and pupa.
The Blephariceridae are currently known from 27 genera and approximately 300 described species, with representatives on most major continents (except Antarctica) and several continental islands (e.g., Madagascar, New Zealand, Sri Lanka). In spite of this wide distribution, regional endemism is high. The subfamily Edwardsininae is restricted to the southern hemisphere -- Australasian Region, southern South America, and Madagascar -- whereas the subfamily Blepharicerinae occurs in both hemispheres. Relationships within the Blepharicerinae remain problematic, especially regarding the widespread Palaearctic / Oriental / Australasian Apistomyiini and their relationship to Neotropical "Paltostomatines." These groups and the Holarctic (North American and Eurasian) Blepharicerini have at various times been ranked as three separate subfamilies (Alexander 1963, Hennig 1973) or as two tribes (Zwick 1977, 1981). Detailed phylogenetic analyses are necessary to resolve the relationships among and within these major subgroups. Relationships within the Apistomyiini sensu stricto are relatively better known than for the Blepharicerini, due largely to the work of Zwick (1977). Deciphering the relationships among Blepharicerine genera remains problematic and contingent upon understanding Eurasian species and their North American congeners. Furthermore, generic boundaries remain especially tentative for some groups (e.g., Agathon). In spite of these difficulties, the world fauna can be classified as follows (known diversity of species in parentheses, primary distributions on right):
Edwardsina (30) southern South America and southeastern Australia
Paulianina (8) Madagascar
Neocurupira (5) New Zealand
Peritheates (2) New Zealand
Nothohoraia (1) New Zealand

Curupirina (3) New Caledonia
Austrocurupira (1) southeastern Australia
Theischingeria (1) northeastern Australia
Parapistomyia (4) southeastern Australia and New Guinea
Apistomyia (16) Australia to southeast Asia, Mediterranean, and Japan
Hammatorhina (2) Sri Lanka
Horaia (3) southern and southeast Asia
Aposonalco (1) Mexico
Elporia (19) southern Africa
Paltostoma (21) Mexico, Caribbean, and South America (Andes)
Limonicola (8) northwestern South America
Kelloggina (34) southeastern Brazil and northeastern Argentina
Hapalothrix (1) Europe
Neohapalothrix (3) eastern Asia
Tianschanella (1) central Asia
Agathon (16) central & eastern Asia, western North America
Asioreas (5) central Asia
Bibiocephala (4) Japan and western North America
Philorus (22) central & eastern Asia, western North America
Blepharicera (44) widespread Eurasia and North America
Dioptopsis (3) Europe
Liponeura (45) Europe
