Comparative diagnostic drawings of 8 species in

and original literature, especially
Yamasaki & Ahmad (2013: 538
, Figs. 30A-G, 31A-E, 42A-F).
Diagnosis
. Female.
"Pipes-like"
sclerotized spermathecae, stretching parallel along the median axis of epigyne, without transverse detour, usually pressed to each other along part of their course, are either thin, gradually slightly dilating along their course in their distal half (located in the anterior part of epigyne), with internal spines as in
T. cuneatus
(Badcock, 1918)
, or making asymmetrical terminal chamber with long internal spines (
Fig. 1I
). They differ from spermathecae in
Myrmage gedongensis
Badcock, 1918
), comb. n. which retain the same diameter along their whole length, devoid of swellings, and covered internally by similar minute spines. Posterior (proximal) ends of "pipes" are diverging, making room for the pocket, located between them. Membranous copulatory ducts, visible after staining, make irregular, large coils, running from almost indiscernible slit-like copulatory openings at the median septum of epigyne, towards the beginning of spermathecae, near the posterior rim of epigyne.
Male. Palps have almost circular bulbus, resembling
Emertonius
by the lack of additional thin loop of spermophor, encircled with the coils of embolus inside semi translucent sheath. Spermophor broad, runs along the margin of bulbus. Tibial apophysis indistinctly double bent, but not twisted screw like (
Fig. 3F
). Chelicerae in both sexes have developed ventral lobe, extending their height, none the less, male chelicerae are long, but shorter than in
Myrmarachne
, with two rows of tiny teeth, fang is long. The size of specimens medium, some species have total length
7-8 mm
. Body compact, constrictions variable, in some species indistinct, with thoracal part depressed, abdomen in some species almost round, in other elongate with two sclerites.

Nomenclatorical note
. Genus name
"
Toxeus
"
was introduced by Koch C.L. in
1846 in
combination with specific name
"
maxillosus
", subsequently used as synonymic combinations with five other specific names, by Thorell, Pickard-Cambridge F., and one Smith (1907). The names of two taxa of the family level, derived from
Toxeus
- Toxeae and Toxeinae were proposed by Pickard-Cambridge F. in 1900 but none were used after
1907 in
primary literature (
Bonnet 1957
, 1959: 2997-3014, 4663). As a name for that genus is accepted reinstated name
Toxeus
, still available according to Edwards (2013, Peckhamia 110.1: 7).
