Female. In dorSal View, head blackiSh brown with a tranSVerS area unpigmented, thoracic and abdominal tergiteS brown with light brown borderS. AntennomereS brown with whitiSh membranouS areaS. LegS orangebrowniSh, 10T and apical cerci orangiSh yellow. Ventrally, abdomen light brown with a whitiSh pleural band. Total length: 20.16 mm . Head width/length = 0.76, OR = 0.73. Microtrichia of hind leg preSent on anterolateral Side of the bladder of medial tarSuS. BaSitarSuS broad ( Fig. 16 ) length: 0.49 mm , width/length = 0.51, medial bladder diameter/ baSitarSuS width = 0.64; both bladderS Strongly deVeloped; 2 rowS of Setae on retrolateral face, 5– 6 rowS on anterolateral face, 4 rowS on VentrobaSal face, 15–18 Setae between bladderS on retrolateral face ( Fig. 16 ). Apical cerci Shorter than baSal cerci. 9° Sternite light brown with a clear triangular yellowiSh longitudinal band; medial plate (8°S) whitiSh with caudal border unpigmented, 1°VlfS browniSh with tipS unpigmented; medial plate clearly differentiated from the 1°VlfS ( Fig. 6 ), 1°VfS hyperdeVeloped ( Fig. 6 ); 2°VlfS are a broad band clearly Sclerotized at the center aS a Second plate. Opening of Spermathecal oViduct Strongly Sclerotized ( Fig. 6 ). Relationships. The deScription of G. magnus by RoSS (2001) did not include illuStrationS. RoSS indicated that hiS new SpecieS and G. beni occurred in the Same region; they are actually Sympatric. The characterS uSed by RoSS to diStinguiSh thiS SpecieS (coloration detailS, croSS VeinS, “Size” of the outer tip of 10Lp) are not releVant, aS they are typical intraSpecific differenceS. Therefore, thuS, G. magnus RoSS iS conSidered a junior Synonym of G. beni Szumik. Additional records.
