Wing base structural data support the sister relationship of megaloptera and neuroptera (insecta: neuropterida).

Zhao C, Liu X, Yang D - PLoS ONE (2014)

Bottom Line: The present study attempts to infer phylogenetic relationships among three orders, Megaloptera, Neuroptera, and Raphidioptera, within the superorder Neuropterida, based on wing base structure.Cladistic analyses were carried out based on morphological data from both the fore- and hindwing base.A sister relationship between Megaloptera and Neuroptera was recovered, and the monophyly of Megaloptera was corroborated.

ABSTRACT
The phylogenetic status and the monophyly of the holometabolous insect order Megaloptera has been an often disputed and long unresolved problem. The present study attempts to infer phylogenetic relationships among three orders, Megaloptera, Neuroptera, and Raphidioptera, within the superorder Neuropterida, based on wing base structure. Cladistic analyses were carried out based on morphological data from both the fore- and hindwing base. A sister relationship between Megaloptera and Neuroptera was recovered, and the monophyly of Megaloptera was corroborated. The division of the order Megaloptera, the traditional higher classification, into Corydalidae (Corydalinae + Chauliodinae) and Sialidae, was also supported by our wing base data analyses.

pone-0114695-g002: Wing base of Sialidae (Megaloptera).(A) Sialis sibirica McLachlan, forewing base; (B) same, hindwing base.

Mentions: The humeral plate (HP) is the basal sclerite of the costal vein. The basisubcostale (BSc) represents the proximal end of the subcostal vein, and is strongly sclerotized. The basiradiale (BR) is the basal sclerite of the radial vein, and is also strongly sclerotized. It is proximally close to the anterior margin of 2Ax. The basanale (BA) is the basal sclerites of the anal veins. The tegula (Tg) is a well-defined field of sensilla trichodea and is usually elevated above the other sclerites.
