The present identification of nigroguttata is based on the original illustration. 
I have found no specimen eligible to be lectotype. 
Specimens of 7. nigroguttata have been studied from southern Mexico and 
Guatemala. Tlagonalia is similar to Graphogonalia, new genus, in the forewing 
and the second valvula of the ovipositor. Males are similar, in the aedeagus 
and paraphyses, to G. vicina, n. sp. 

FIGURE 842.—Tlagonalia nigroguttata (Signoret) (1-k, m, n, g, from specimens 
from Chiapas, Mexico; remainder from Jalapa, Vera Cruz, Mexico; only 
apex of aedeagus shown in g; arrows indicate extremities of toothed portion 
in k): p, Aedeagus and paraphyses, from lateral view; g, apex of forewing.
