Diagnosis of adults

Epistome of species of this genus with three anterior extensions, the anteromedial aciculate, spatulate or lanceolate, smooth or serrate, usually longer than the others (except G. elegantellus , G. elongatellus and G. pilosellus , which have the three extensions of similar lengths). Arthrodial process of chelicera in the form of a short coronet-like fringe. Dorsum of idiosoma totally covered by a large shield, extending lateroventrally, abutting the peritrematic shield and fusing with ventrianal shield posteriorly. Endopodal shield totally fused to sternal shield, composing a single unit that extends to level of posterior margin of coxa IV and which has a deep posterior concavity fitting the tongue-shaped genital shield. Exopodal shield distinctly represented by a subtriangular section between coxae I and II (not always clearly distinct) and an elongated section running from middle of coxa II to middle of coxa IV, the latter separated from the peritrematic shield by a line of unsclerotized cuticle; fused peritrematic shield and section of exopodal shield around posterior half of coxa IV extending posteriorly well beyond stigma, wider immediately behind coxa IV and progressively narrowing posteriorly to a pointed tip; separated from adjacent shields by lines of unsclerotized cuticle.
