Arnoldi (1968) erected the genus Leonomyrma for a single new 
species, L. spinosa, which he had collected in July, 1949, near 
Peremetriaja, East-Kasachstan (USSR), at the lower course of Ural 
River. Up until present, only the type series of 4 22 and 14 $$ have 
been known; no 2 2 were found. In the course of a study in mor- 
phology and behavior of several species of the ant genus Chale- 
poxenus, I came across the description of Leonomyrma. A direct 
comparison of its holotype (2) and an allotype (3) with material of 
two Chalepoxenus species, C. muellerianus (Finzi) (= C. gribodoi 
Menozzi) and C. kutteri Cagniant, clearly revealed the synonymy of 
the two genera. 
Genus Chalepoxenus 
Chalepoxenus Menozzi, 1922: 257, worker, female. Type species by original designa- 
tion: C. gribodoi. 
Leptothorax (Temnothorax) muellerianus Finzi, 1921: 118, synonymized with 
Chalepoxenus by Muller 1923: 98. 
C. gribodoi Menozzi, 1922: 257, synonymized with C. muellerianus (Finzi) by Kutter 
(1973). 
Leonomyrma Arnoldi, 1968: 1809, female, male. Type species: L. spinosa, mono- 
basic. NEW SYNONYMY. 
Since the original description of Leonomyrma was published in 
Russian, I provide an English translation of its main contents: 
“ Leonomyrma K. Arnoldi gen. n. (Leptothoracini)” 
“Type of the genus: Leonomyrma spinosa K. Arnoldi sp. n. 
Female: Head elongate rectangular. Antennae 12-jointed, 
* Manuscript received by the editor August 14, 1986.
