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. Myrmatheca Prószyński, 2016 gen. n. (2 species)
[proposed as partial synonym for the genus Myrmarachne ].

Type species Myrmarachne alticephalon Yamasaki & Ahmad, 2013
ETYMOLOGY. Name combines words Myrmarachne and spermatheca, assumed grammar gender - femininae.

Diagnosis (Figures 77-79)."Pipes-like" sclerotized spermathecae are modified in into a pair of huge distal chambers in anterior part of epigyne, resembling two tightly pressed sclerotized hemispheres, followed by minute, thin and short, thread-like proximal parts of pipes, with slightly more distinct, transverse parts, expectedly harboring armatures of junction with copulatory duct, and of a scent gland. These should be examined under higher microscope power. Membranous copulatory ducts seem to coil around distal parts of "pipes", but are not sufficiently visible on enclosed photo. Pocket very small and thin, moved ahead towards center of epigyne, reaching level of spherical chambers of spermathecae. Antero-median rim of "windows", on both sides of posterior pocket, is light sclerotized.
Males have chelicerae long, anteriorly swollen. Bulbus oval, spermophor broad, with indistinct, thin duct anteriorly. Tibial apophysis short, inclined and waving, apically narrowing. Body shape of male and female shown on Figures 74-79, cephalic part much higher than thoracal one.
Remarks. Grace to excellent photograph of stained microscopic slide by T. Yamasaki, we have learned structure of the astonishing spermatecae of his Myrmatheca alticephalon, whose details can be interpreted only by comparison with evolution of other genera of MYRMARACHNINES.
Integral part of the definition are drawings below.

Distribution. Two species in Borneo: Sabah, of which one is pending description. A specimen reported from Indonesia: Sumatra: Padang pending confirmation of conspecificity, the third species is described from Madagascar.
Composition. The following species are transferred from genus Myrmarachne MacLeay, 1839: Myrmatheca alticephalon (Yamasaki, Ahmad, 2013) comb. n., Myrmatheca ransoni (Wanless, 1978) comb. n., undescribed species was photographed by P. Koomen.
