Myrmica ademonia

In the Russian Far East M. ademonia is a forest species, living in mixed and deciduous forests and nesting mainly in decayed wood, rarely in soil. In Korea it lives in mixed and deciduous forests (oak, maple, elm, pine, fir) mainly at altitudes between 600 and 1500 m, although it also has been found living in relatively wet places at lower altitudes (ca.0200 m). As in Russia, it usually nests in decayed wood and very rarely in soil under stones. The preference for decaying wood appears to be one of the main ecological differences from Myrmica sulcinodis that usually nests directly in coarse, sandy soil or under stones. (Radchenko and Elmes 2010)

Identification
Myrmica ademonia is most similar to Myrmica sulcinodis and is a member of the sulcinodis species complex of the lobicornis-group. It differs from M. sulcinodis by its longer propodeal spines, less coarsely sculptured petiole, and well-developed petiolar peduncle.(Radencko and Elmes, 2010)

 *  ademonia. Myrmica ademonia Bolton, 1995b: 277. Replacement name for aspersa Kupyanskaya, 1990: 105. [Junior primary homonym of aspersa Smith, F. 1865: 72.] See also: Radchenko & Elmes, 2010: 79.

Description
The propodeal spines are very long and sharp and are directed upwards at an acute angle.

Type Material
Myrmica aspersa - One worker syntype in, one worker syntype in. Both labelled “M” (= Morotai I.). syntype has a Donisthorpe type-label.

Etymology
Radchenko and Elmes (2010) - apparently Bolton made-up this replacement name, loosely basing it on the word ademptio meaning "to take away" (Barry Bolton, pers. comm.). Interestingly, in medicine the name means sad, weary or depressed which may have described Bolton's mood at having to find another replacement name, but more appropriately, the Ademonia family have red and black among their heraldic colours.
