Nomenclature of the veins of the fore-wing of Teleogryllus oceanicus

Name of veinAbbreviationDescription
Costa Anterior edge 
Subcosta Sc Strong vein with branches towards anterior edge of wing 
Radius Strong vein between Sc and M 
Media With Sc and R forms the lever that drives wing opening and closing 
Cubitus 1 Cu1 Its ascending and descending branches form the distal edges of the harp 
Cubitus 2 Cu2 Forms the proximal edge or base of the harp and bears the file on its underside 
Anal 1 A1 Runs parallel to and adjacent to Cu2, fusing with Cu2 near the anal node 
Anal 2, 3 A2, A3 Veins traversing the anal area and meeting at or near the anal node

Nomenclature follows the Comstock—Needham system(Comstock, 1918; Snodgrass, 1935) and the description given by Ragge(1955). The veins are named in order from the anterior to the posterior edge; Fig. 1 follows this usage. The C, Sc, R and M veins form the lateral or anterior field of the wing; The anal veins are somewhat ill-defined — that part of the wing is termed the anal area; the region in which Cu1, Cu2 and the anal veins run is the dorsal or posterior field of the wing.
