Holotype, no. 17025, M. C. Z. apterous male, San Fidelio, 
Brazil, February, Thayer Expedition. Allotype , apterous 
female, Rio Janeiro, Brazil. Paratype, winged male, taken 
with holotype. 
This species is most closely allied to Limnogonus recurvus 
D. & H., from which it may be separated by the propor- 
tional lengths of the antennal segments and especially the 
structure of the male genitalia. In the former the first 
genital segment bears a large prominent and strongly tumid 
protuberance in front of its apical hook.
