Odontoceridae Wallengren

Odontoceridae Wallengren, 1891: 12 [listed as a family without description].

Odontoceridae Ulmer, 1907c : 11,122 [first description of the family].

The forewing postanal vein (sensu Schmid 1998) forms a synapomorphy supporting the monophyly of Philorheithridae and Odontoceridae (Weaver et al. [submitted]). Sexual dimorphism is frequent in the wing venation of several species in the family. A sclerotized and microtrichous forewing anal lobe is frequently present on the base. The wing venation is variously reduced compared to the Philorheithridae . In the forewings, the discoidal cell is present and closed, and the median cell is open or absent in both sexes; the thyridial cell is present in females, but lacking in the males of the 2 genera Marilia and Psilotreta , and in Pseudogoera since the M stem is missing. The extinct species Electrocerum pedestre Ulmer from Baltic Amber, and extant members of the genera Barypenthus Burmeister , Namamyia Banks , Perissoneura McLachlan , Barynema Banks , Parthina Denning , Nerophilus Banks , Pseudogoera Carpenter , Lannapsyche Malicky , Phraepsyche Malicky & Chantaramongkol , and Anastomoneura Huamantinco & Nessimian all have closed thyridial cells in the male forewings. Reduction of the median vein occurs otherwise only in the Molannidae and in the Beraeidae . Mesoscutellar setal warts are usually single, large, ovoid and sparsely covered with setae, but in Barypenthus they are paired and small. The apicomesal nodule on the first maxillary palp segments is usually absent, but may be present in some taxa, like in species within Lannapsyche .
