Triapitsyn, sweeping grass infested with  Draeculacephala mollipes(Say)[ 1 ♀, UCRC].   Redescription. See Huber (1988).   Diagnosis.  Gonatocerus( Gonatocerus) koebeleiis distinguished by the following combination: female antenna ( Fig. 40) with F6 bearing 1 or 2 mps; forewing ( Fig. 42) with a brown apical spot; ovipositor exserted beyond apex of gaster ( Fig. 41) by 0.20–0.25x own length. The boundaries among four similar species,  G. koebelei,  G.( Gonatocerus) rivalisGirault,  G.( Gonatocerus) antillensisDozier, and  G.( Gonatocerus) urocerusOgloblinmay need to be re-assessed because currently they can be separated only based on variable characters, such as presence or absence and number of mps on F6 of the female antenna, presence or absence of an apical brown spot on the forewing, and degree to which the ovipositor is exserted.   Distribution.NEOTROPICAL:  Mexico( Veracruz). NEARCTIC: USA( Florida).   Hosts.  Draeculacephala mollipes(Say),  D. producta( Walker) ( Huber 1988), and an unidentified leafhopperon sugar cane ( Perkins 1912) ( Cicadellidae).
