Redescription. See Huber (1988). An earlier redescription of G. mexicanus by Ogloblin (1955) was based on the two females from Salta, Argentina. Neotropical specimens of this species are very similar to the Nearctic ones.

Diagnosis. Gonatocerus (Gonatocerus) mexicanus is distinguished by the following combination: female antenna as in Fig. 43 ; forewing ( Fig. 46 ) without brown band; mesosoma as in Fig. 44 ; petiole reduced to a very narrow ring; ovipositor ( Fig. 45 ) exserted almost by 0.4x own length beyond apex of gaster (extent it is exserted varies).

Distribution. NEOTROPICAL: Argentina, Costa Rica *, Cuba ( De Santis 1979), Honduras *, Mexico, and Panama *. NEARCTIC: Canada ( Huber 1988), Mexico, and USA. OCEANIA: Hawaiian Islands ( USA: Hawaii).

Hosts. Draeculacephala mollipes (Say) , D. minerva Ball , D. producta (Walker) [as D. cubana Metcalf & Bruner ], Draeculacephala sp., an unidentified “green rice leafhopper ” ( Cicadellidae ), and Podops sp. ( Hemiptera : Pentatomidae ) ( Huber 1988; Huber & Beardsley 2000). The pentatomid record needs confirmation because true bugs are unlikely hosts for Gonatocerus species.
