Type-species: Hodostatus brevis Thomson. By subsequent monotypy from inclusion 

 by Thomson, 1883.

Trevtatopygus rotundatus Davis, 1897. Amer. Ent. Soc, Trans. 24: 277. 6, 9. 



Gnesia caliroae Rohwer, 1915. U. S. Natl. Mus., Proc. 49: 220. 9. Rohwer erroneously 

 stated that notes under Hopkins' number 11381 pertaining to the holotype record the 

 species as being reared from a species of Caliroa which feeds on Nyssa sylvatica. 

 Actually the notes record the holotype as having emerged on Aug. 10, 1913 from a larva 

 of Caliroa {="Eriocanipoides") collected on July 7. 1913 feeding on Castanea detitata. 

 D. R. Smith has informed me (personal commun., 1976) that Caliroa lorata is the only 

 species of its genus which he knows to feed on Castanea.
