Dorsal coloration brown to very dark brown ( Fig. 2A). Thoracic and abdominal venter dark brown ( Fig. 2C). Maxillary palps uniformly yellow ( Fig. 3A). Aedeagus ( Fig. 7B–E) with basal piece short, less than one-third the length of the parameres; outer margins of parameres distinctly curved inward. Median lobe broad, gradually tapering from the base to the apex into a blunted point, apex even with to slightly longer than the apex of the parameres; gonopore situated in the middle to apical third.  Variation.The dorsal coloration varies from a medium to very dark brown; we have not observed any nonteneral specimens that are as pale in color as  G. flavus. The aedeagus also exhibits some variation with regard to degree of curvature of the outer margins of the parameres (may be weakly to strongly inwardly curved along their entire length), and the relative extension of the median lobe (may be even with the apex of the parameres or extending beyond them). The opening of the gonopore also varies in position, from being situated in the middle of the median lobe to being located more apically (compare Fig. 7C with 7D and 7E). There was no clear correspondence in these characters with geography or the genetic groups found in Fig. 1.   Distribution. Venezuela( Bolívar), Guyana, Suriname, Brazil( Amazonas, Pará).   Biology.All known collecting events were from lotic habitats, primarily along the margins of small to medium sized streams and small rivers (e.g., Fig. 7B–D). Most of these habitats had at least some sand substrate and decaying organic matter such as leaf litter. It has been collected on the summit of one low-elevation Tepui (Tafelberg) in Suriname.   Remarks.The aedeagus of the holotype( Fig. 4) had been mounted on a slide under a coverslip and stored vertically. When we observed the slide, the genitalia had migrated out from under the coverslip to its margin and had become distorted. We soaked the slide in water and dismounted the aedeagus, but it was in very poor condition. What remains has been placed in glycerin in a microvial and pinned beneath the specimen. The correct original spelling of the specific epithet,  hemisphericus, is an incorrect transliteration of “  hemisphaericus”. This type of spelling error is uncorrectable (ICZN 32.5), thus the correctly transliterated form listed in Short & Hebuaer (2006) is to be considered an incorrect subsequent spelling. 1434655244 1999-10-23 MALUZ Col. & Julio Gonzales & Jesus Berti & Edith Navarro & Holotipo & Dcrip.
