Description of male. Coloration (after ca 6 years in alcohol). Body creamy white, with the following exceptions: anterior margin of frons with broad brown band; centripetal margins of ocellidarkbrown;f 1 light brown, f 2 light brown basally merging to dark brown apically, remaining segments dark brown; eyes black; prothorax with brown pleural stripe.

Vertex flattened, elongated. Labrum and lacinia as G. micropterus . Epiproct (fig. 85). Paraproct (fig. 85) with small field of papillae and ovoid dome of 10 trichobothria, one seta not in rosette. Hypandrium (fig. 86) median region lacking setae, membranous; posterolateral margins with few strong setae; pair of strong median preapical setae. Phallosome (fig. 87) relatively narrow.
