Myrmecium Latreille, 1824 is a relatively large genus of Castianeirinae with 16 species, distributed exclusively in the Neotropics (WSC 2015). Although this genus is rather well known as a good example of ant mimicking spiders, its taxonomy is very poorly studied. Two of its species are described based on unknown sex; one species is described based on a juvenile; eight species are known based on a single sex: for seven, only females are known, and for one, only a male is known (Platnick 2014… 
A Species Richness Hotspot of Ant-Mimicking Sac Spiders (Araneae: Corinnidae: Castianeirinae) at the Bolivian Orocline, With New Country Records for Three Genera and Nine Species
TLDR
A species richness hotspot of ant-mimicking (or myrmecomorphic) spiders of the subfamily Castianeirinae Reiskind, 1969, is reported from the premontane Chiquitano forest at the Bolivian orocline, providing an excellent opportunity to gain further insight into the factors determining the evolutionary ecology and ant mimicry in Castianeirae communities.
On the type species of the genus Aetius O. Pickard-Cambridge, 1896: The first description of male with notes on cymbial notch and mating plug (Araneae: Corinnidae: Castianeirinae).
TLDR
Dankittipakul & Singtripop (2013) described the male of A. nocturnus, thereby revealing the male genitalia of the genus, but the type species was still known only from the female sex.
