Diagnosis.

Hind tarsus is relatively short (less than 1 mm, Fig. 4a); male phallic complex with pseudepiphallic ancorae short and roughly rounded with no dorsal branch. Ventral appendage of pseudepiphallic ancora somewhat predominant with both ends roughly square (Fig. 4b); male tenth abdominal tergite bituberculate, with scarce hair but without long strong spines (Fig. 4c); female ovipositor notably short and spoon-shaped in lateral view. Apical valves on both dorsal and ventral margins rounded, more than in other Myrmecophilus species (both Myrmecophilus americanus and Myrmecophilus albicinctus have rounded valves, with those of latter being more rounded) (Fig. 4d, e).
