Procryptotermes

Soldier: Head reddish, rectangular, with brown-black inner edge; total length 4–5 mm. Head with a protuberance secreting an adhesive substance. Mandibles long, sickle-shaped, distinguishing Procryptotermes from most other Kalotermitidae. Imago: Hind wing with Sc absent (presumably fused to C); M poorly sclerotized, diverging from Rs apical to but near the basal scale, then arcing anteriorly to terminate into Rs beyond wing midlength; R1 simple, comparatively short, extending to slightly more than one-third wing length, terminating into costal margin well before the tangent at which M fuses with Rs; CuA field encompassing at least one half of wing width, with numerous, largely simple branches.
