(Figs 40–42)

Gonatoceus [sic] koebelei Perkins 1912: 22 –23. Lectotype female [BPBM], designated by Huber 1988: 41 (not examined). Type locality: Orizaba, Veracruz, Mexico.

Lymaenon koebelei (Perkins): Burks 1958: 63 (catalog); Peck 1963: 23 (catalog).

Gonatocerus (Gonatocerus) koebelei Perkins: De Santis 1979: 365 –366 (catalog).

Gonatocerus koebelei Perkins: Huber 1988: 40 –42 (assigned to sulphuripes species group, lectotype designation, diagnosis, redescription, records from Florida (USA), host associations).

Material examined. None.

Extralimital record. USA. FLORIDA, Palm Beach Co., Belle Glade, University of Florida Everglades Research and Education Center, 19.viii.2001, S.V. Triapitsyn, sweeping grass infested with Draeculacephala mollipes (Say) [1 ♀, UCRC].

Redescription. See Huber (1988).

Diagnosis. Gonatocerus (Gonatocerus) koebelei is 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) rivalis Girault, G. (Gonatocerus) antillensis Dozier, and G. (Gonatocerus) urocerus Ogloblin may 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 leafhopper on sugar cane (Perkins 1912) ( Cicadellidae).
