Prószyński, Jerzy, 2016, Delimitation and description of 19 new genera, a subgenus and a species of Salticidae (Araneae) of the world, Ecologica Montenegrina 7, pp. 4-32 : 9

Gen. Myrmapeni Prószyński, 2016 gen. n.

Figures 2E , 3E , 4G–H

Type species. Myrmarachne penicillata Mello-Leitao, 1933 from Brazil .

Documentation studied. Comparative diagnostic drawings of 3 species in Prószyński (2016a) and original literature.

Etymology. Name combines words Myrmarachne and penicillata , grammar gender assumed feminine.

Diagnosis. Female. 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 ( Fig. 2E ). 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. As only one female is known in this genus, 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 ( Fig. 3E ). Palpal tibia is short and relatively wide, bulbus circular, with distinct additional thin loop of spermophor. Body with shallow abdominal, dorsal constriction, chelicerae with ventral lobe, dorsally flat, broad ( Figs. 4G–H ).

Distribution. Central and South America, however, one species is found in Sarawak, another one in Madagascar.

Composition. The following species are transferred from genus Myrmarachne MacLeay, 1839 : Myrmapeni borneensis (Peckham, Peckham, 1907) comb. n., M. chickeringi ( Galiano, 1969) comb. n., M. diegoensis ( Wanless, 1978) comb. n., M. penicillata (Mello-Leitao, 1933) comb. n., M. simplexella Roewer, 1951 comb. n., M. sumana (Galiano, 1974) comb. n.
