13D818D1E9B555E6AB3C39D6C80169DC.taxon	description	Description. Lateral cranial margins converging anteriorly; cranium not bulging towards vertex. Genal angle laterad antennal toruli obtuse. Outline of clypeus campaniform in full-face view, laterally elevated above cranium, posteriorly not elevated above frons; clypeal surface planar; anterior clypeal margin slightly emarginate, posteromedian clypeal margin emarginate; median clypeal ridge present on mesal surface of clypeus, externally visible. Labrum visible in full-face view; anterodorsal apex of labrum armed with three or four dentiform, peg-like chaetae; venter with vestiture of suberect lanose setae. Mandibles elongate relative to head (CI = 79 - 80), linear, apex curved downward distally; vertical dorsal lamella absent; laterodorsal longitudinal groove present; dorsomedial margin of mandible with single row of ~ 12 dentiform, peg-like chaetae; lateral mandibular face glabrous. Labial palp 1 - merous. Anterior tentorial pits faint, situated anterad the toruli, not visible in full-face view. Postgenal ridge complete. Scape long (SL 0.34 - 0.39 mm), reaching slightly beyond occipital margin when antennae retracted. Flagellum submoniliform; apical flagellomere 3 x longer than broad. Pronotum broader than mesonotum in dorsal view, with lateral margins convex. Mesonotum narrow, with lateral margins parallel in dorsal view. Meso-metapleural suture narrow laterally, broader along dorsal surface; scrobiculate, with transverse ridges larger and more widely spaced along dorsal surface of meso-metapleural suture; posteriorly distinct from metapleural trench. Maximum breadth of metapectal-propodeal complex greater than that of mesonotum in dorsal view, slightly narrowed anteriorly, posterior outline convex in profile view. Bulla large, extending anterior to propodeal spiracle. Propodeum rounded in profile view. Tarsomeres longer than broad. Meso- and metatibial spur formula 0,1 p. Petiole sessile. Abdominal segments II and III without tergotergal and sternosternal fusion. Abdominal segment II slightly longer than wide in dorsal view (PI 94 - 99), with distinct dorsal node, in profile view anterior and posterior faces subequal in height; anterior face of petiolar node linear in profile view. Subpetiolar process present, abdominal sternite II with concavity posterior to subpetiolar process so that margin of abdominal sternite II is sinuate in profile view; fenestra present, elliptical, anteroposteriorly compressed. Lengths of abdominal segments II-III subequal. Abdominal sternite II projecting no further than abdominal sternite III towards venter. Abdominal segment III slightly broader than long in dorsal view (PPI = 105 - 113), with distinct dorsal node; in profile view, anterior face of dorsal node abruptly vertical and bulging, posterior face gently sloping. Post-petiole with distinct tergosternal suture. Abdominal segments III-IV separated by pronounced constriction, with presclerites of abdominal segment IV distinct; pretergite IV planar in profile view, shorter than presternite IV; presternite IV slightly convex in profile view; cinctus of abdominal segment IV scrobiculate. Anterior margin of abdominal post-tergite IV shallowly emarginate in dorsal view. Outline of postpetiolar node trapezoidal in dorsal view, corners rounded, slightly narrowed anteriorly. Soma concolorous, color castaneous. Vestiture of suberect to erect setae present; length of setae variable.	en	Griebenow, Zachary (2024): Systematic revision of the ant subfamily Leptanillinae (Hymenoptera, Formicidae).

13D818D1E9B555E6AB3C39D6C80169DC.taxon	etymology	Etymology. Named for Alfred Russel Wallace, commonly thought to be the progenitor of the discipline of biogeography and still well-regarded for his study of the biota of the Malay Archipelago, where this ant is native. The specific epithet is masculine, in genitive case.	en	Griebenow, Zachary (2024): Systematic revision of the ant subfamily Leptanillinae (Hymenoptera, Formicidae).
