This species stands nearest to A. quadrilineata (Clap. & Lachm.) 
Jørgensen, but is easily distinguished by its acute end.

In most of the specimens observed the curvature of the apical 
end is not so pronounced as in the quoted figure by Daday, and 
often the apex is nearly straight. For such forms I propose the name: 
T. curvicauda Daday f. subrecta. This form is the predominant 
in our area, but I have also met with a few specimens not diffe- 
ring from the type.
