Type species. Panachraesta paludosa Simon, 1900 .

Documentation studied. 1) Syntype specimen from Sri Lanka, revised by Prószyński (1987: 74) and described again by Benjamin (2015: 21-26, Figs 13A-B, 14A-G, 15A-H, 16A-D).

2) Specimens illustrated and described by Benjamin (2015: 21-26, Figs 14A-G, 15A-H, 16A-D), considered by him as Myrmarachne paludosa (not seen).

Remarks. This genus does resemble MYRMARACHNINES by epigyne with two white "windows" and the translucent, long "pipes" of spermathecae. The photograph of dorsal habitus and the epigyne of female syntype provided by Benjamin (2015, Fig. 13A–B) agree with drawings by Prószyński (1987: 71, unnumbered) with minor differences due presumably to the individual variation of specimens studied. However, his excellent documentation (Figs. 14a-16d) seem to indicate mixing up several species of the genus, in particular females show different shape of abdomen, broadest at 2/3rd of its length and the triangular posterior tip of abdomen, also his newly photographed alive and preserved specimens show the slight constriction of abdomen, increased by fine white band – these should not disappear without trace, even from long time preserved syntype. Therefore I hypothesize that these specimens represent different, although related species. The internal structure of epigyne and palps presented in the same paper by Benjamin indicate resemblance to some Toxeus ( T. cuneatus (Badcock, 1918) , comb. n. or T. jajpurensis (Prószynski, 1992) , comb. n.). While placement in Toxeus require confirmation, the transfer of Panachraesta paludosa to the genus Myrmarachne is not accepted and the original combination is hereby reinstated, pending further research. With the uncertain matching of female, the placement of male is also suspended, pending further research.

Composition. Single species described from Sri Lanka.
