Note on illustrations. This introduction to classification of Salticidae includes only species defined by diagnostic illustrations in the taxonomic literature, arranged by similarities of embolus and spermophor. Images are displayed as thumbnails to save space and allow for rapid scanning of theoretically closely-related species. Thumbnails are small versions of illustrations in other parts of the monograph, whera are displayed together with particulars of their sources and permissions. .

Gen. Myrmapeni Prószyński, 2016 gen. n. (6 species)
[proposed as partial synonym for the genus Myrmarachne (in part)].

Type species Myrmarachne penicillata Mello-Leitao, 1933 from Brazil.
ETYMOLOGY. Name combines words Myrmarachne and penicillata, grammar gender assumed feminine.

Diagnosis. Spermathecae have typical for MYRMARACHNINES "pipes-like" appearance, but with unusual wide divergence of their proximal parts (that is topographically posterior), in addition their proximal ends are twisted into a small coil. Copulatory ducts are not marked on drawing of epigyne, presumably can be membranous, like in other related genera. External epigyne is unusually broad, with "windows" anterior and set obliquely, pocket small, posterior. These epigyne structures are known in only one species - Myrmapeni chickeringi (Galiano, 1969) comb. n, it is impossible to tell whether are they representative for the whole genus, or unique for this species only.
Male palps are characterized by unusual bunch of long, black setae on palpal tibia, near apophysis. Palpal tibia is short and relatively wide, bulbus circular, with distinct additional thin loop of spermophor. Chelicerae with ventral lobe, dorsally flat, broad. Body shape of male shown on drawing below.
Integral part of the definition are drawings below.
REMARKS. Distributed in Central and South America, however, one species is found in Sarawak, another one in Madagascar.
