Head, excluding mandibles, one-seventh longer than broad, rectangular with feebly convex sides rounding into evenly concave occipital margin and feebly convex anterior clypeal margin. Mandibles trigonal with acute apical tooth and finely denticulate cutting margin. Frontal lamina projecting as acute, feebly divergent teeth. Antennal scrobes bordered laterally by strong carinae. Eyes lacking. Antennae 9-jointed; scape strongly clavate, extending slightly more than half-ways to occipital margin; funicular joints 2-7 distinctly broader than long, terminal joint long-elliptical, longer than preceding three joints taken together. Thorax from above sub-rectangular, slightly over twice as long as broad, with convex pronotal margin and sides slightly impressed at meso-epinotal suture; in profile evenly and slightly convex. Epinotal declivity plane, feebly carinate on sides. Petiole from above trapezoidal with feebly convex sides converging anteriorly and convex posterior margin; in profile with rounded dorsum, higher anteriorly, and large ventral lobe produced anteriorly. Postpetiole from above trapezoidal with feebly convex sides converging anteriorly, a little longer than petiole and one-fourth wider; in profile with basal half produced anteriorly as a large lobe and with feebly convex dorsum.</p><p>Gaster from above ovate, 1st gastric segment comprising about nine-tenths of gaster. Legs short, with thickened femora and tibiae; basal tibial joint of prothoracic leg equal in length to distal four taken together. Sub-lucid; with dense and moderately coarse setigerous punctations. Moderately pilose, with fine reclinate to recumbent yellowish white hairs interspersed with much longer, sparser, and more upright hairs. Color uniformly yellowish brown.</p><p>Described from a series of workers taken in small tunnels in red clay in the same banana plot at St. Augustine, Trinidad, B. W. I., but in two different years, May 17, 1935, and May 20, 1936. The first year I found them in small tunnels just above the fungus gardens of a nest of Acromyrmex octospinosus Reich between four mature banana stalks. The ants were at first thought to be dorylines because they beat their antennae upon the ground before them as they crawled along in single file, precisely as do the army ants. This observation further substantiates the removal of this group of ants from the ponerines to a separate subfamily, the Cerapachyinae . They were not strongly negatively phototropic but "felt" their way cautiously in their tenuous tunnels. One worker was carrying beneath it with ease a larva, fully two-thirds its own length, whose long axis was parallel to that of the ant. When the two were put in alcohol the worker maintained its grip for many seconds. Another larva was resting in an L-shaped position but was soon carried off. A single worker was taken nearby August 3, 1935, among leaves at the base of a saman tree ( Pithecolobium saman). When the banana plot was revisited in 1936 workers were found at the base of a mature banana clump in small tunnels from near the surface to a depth of at least 12 cm. Brood was found, not in a single brood chamber, but in small pockets off from the tunnels and of only slightly larger dimensions. Their doryline behaviour was again noted.</p><p>This species differs from cotypes of Syscia silvestrii Wheeler of Hawaii in the Museum of Comparative Zoology in slightly smaller size, shorter antennal scapes, more rounded postpetiole, seen from above, and in paler color. Judging from the description and drawing of Syscia seini Mann of Puerto Rico, ierensis differs in slightly larger size, longer head and antennal scapes, less impressed sides of thorax, proportionately broader and more convex postpetiole, seen from above, and in other ways. The three species are evidently closely related.</p><p>The poetic Indian name for Trinidad is Iere, land of the humming bird.</p></div>	https://treatment.plazi.org/id/8950EC3A381FDA5763639286F6EEE055	Public Domain	No known copyright restrictions apply.

Thorax in profile slightly impressed at pro-mesonotal and meso-epinotal sutures. Epinotal spines from above diverging, slightly longer than the width of the basal surface in front of them, in profile straight, directed backwards and upwards. Petiole with spine distinctly longer than epinotal spines and forming dorsally an obtuse angle, ventrally a concavity. Gaster ovate.

W. I., December 15, 1934. The ants were taken at about 10 p. m. as they crawled over the leaves of bromeliads growing close to the ground in the dripping wet, mossy rain forest. Tree frogs ( Amphodus auratus, Eleutherodactylus urichi, and Gastrotheca fitzgeraldi) were also out on the leaves and snapped up passing ants but the stomachs of those examined did not contain the Acanthoponeras.</p><p>Of the two known species of the subgenus Acanthoponera in the New World with their two varieties and a subspecies, this new species is closest to goeldii ssp. schwarzi Wheeler which is known from the single worker taken in Guatemala. These are the two smallest forms and are closely related. From schwarzi (comparing with the type in the Museum of Comparative Zoology) this new species differs in possessing stouter epinotal spines, less deflected petiolar spine, coarser sculpturing of head and thorax, less pilose head, and in darker color.</p></div>	https://treatment.plazi.org/id/90026B207FB82C0A15643B4EEB48F779	Public Domain	No known copyright restrictions apply.

W. I., July 29, 1935. Intensive collecting in both localities failed to reveal other workers and testifies to the extreme rarity of these archaic ants. Both specimens were among leaves and, as there were no land snails in either place, a snail-eating habit could not be inferred (cf. Creighton, 1928). It is more probable that the bizarre mandibles are used for capturing other Arthropods (cf. the myriapod-eating habit of Emeryella schmitti discovered by Dr. Mann (Wheeler and Mann, 1914). Similar bizarre mandibles are common in Strumigenys and I have found a Strumigenys worker carrying a collembolan ( Entomobrya sp.), controvening a theory that the ants of this genus fed on fungi.</p><p>Of the previously known three species this new species is closest to T. ferox discovered by Dr. W. M. Mann in Honduras. It is larger than cochlearis or mutilatus and smaller than ferox . From cochlearis it differs further in lacking punctate sculpturing on body and fine ridges radiating back from clypeus, in proportions of thorax and petiole, in more anteriorly diverging head, and in mandibular teeth proportions. A cotype of ferox differs from this new species in having the pronotum more convex laterally, in having an even convexity between the pro- and mesonotum, in having the petiole more bi-convex and less plano-convex when viewed laterally, in having distinctly thicker petiole apex, in having a shorter head and in mandibular teeth proportions. Sculpturing and pilosity are similar.</p><p>Dr. W. M. Mann kindly allows me to describe a fifth species which he took at Huachi Beni, Bolivia:</p></div>	https://treatment.plazi.org/id/9E2F3563490FC003A33A02D30A001A06	Public Domain	No known copyright restrictions apply.

From the female of D. neotropica Bruch of the Argentine this species differs in proportions of antennal joints and in having the plate between the antennal scape bases toothed. Of neotropica (known only from the type female) Dr. Bruch writes (Bruch, 1919) "Respecto al número reducido de los artejos antenales en D. neotropica (9 en el genotipo), he creído bien consultar al Dr. Santschi de Kairouan. Mi distinguido colega me aconsejó conservar el nombre generico, y opina que la contracción de estos artejos es tal vez instable, habiéndola observado con Discothyrea Traegaordhi Sants., y en una preparación en bálsamo de Canadá, donde no constan sino 6 artejos, los otros todos más o menos soldados e indefinibles." I am therefore leaving this species in the genus Discothyrea . The possibility that the genotype, testacea, described in 1863 presumably from "North America" and not recorded since, may also show variability in antennal joint number must be entertained. That it cannot be this species is indicated by the size of testacea (1.5 mm. for worker, 2 mm. for female), among other differences.</p></div>	https://treatment.plazi.org/id/9015BCE6CB2568578682CFACCD546180	Public Domain	No known copyright restrictions apply.

Head quadrangular, with rounded occipital corners and impressed occipital margin; eyes absent; clypeus convex in middle; antennae 12-jointed, slender, scapes not reaching occipital margin; mandibles long and narrow with sinuate outer margin, slender, acute apical tooth, and two distinct pre-apical teeth with smaller tooth between the latter. Thorax with higher, convex pro-mesonotal region and lower, more plane epinotum, the latter laterally compressed and without carinae or teeth. Petiole rounded-cuneate, ventrum convex, not dentate. Gaster of moderate proportions with distinct impressions at sutures, sting projecting. Legs moderately short; middle and hind tibiae with two spurs, the outer being simple and small, the inner large and pectinate.</p><p>Sculpturing fine, without coarse punctations or rugae.</p><p>Pilosity of fine, dense pubescence and sparse, fine, upright hairs.</p><p>Color light brown.</p><p>Female.-Slightly larger than worker. Winged.</p><p>Genotype: Wadeura guianensis, sp. nov.</p><p>Wadeura is close to Pseudoponera of the Indomalayan and Ethiopian regions, to which it runs in the late Dr. Wheeler's key. It is separated by the absence of eyes and nature of mandibular teeth. Of the two subgenotypes of Pseudoponera, P. amblyops Emery and Promyopias silvestrii Santschi, Wadeura guianensis comes closer to amblyops in mandibular structure but lacks the well-formed eyes; it comes closer to silvestrii in reduction of eyes. P. silvestrii was originally described as a subgenus of Myopias but may deserve to rank as a distinct genus. The three could then be grouped as follows: Pseudoponera (Indomalayan)- Wadeura (Neotropical)- Promyopias (Ethiopian) (Fig. 7a-c).</p></div>	https://treatment.plazi.org/id/6FAC7954FD7809A801B5F77546B0E748	Public Domain	No known copyright restrictions apply.

A small colony consisting of a half dozen workers, a queen and larvae was found a few centimeters down in sandy loam in high rain forest with many Brazil-nut trees ( Bertholletia excelsa or nobilis). The nest was in the form of irregular chambers. The queen had a larger thorax than the workers and had evidently borne wings. The entire colony was gathered and the worker here described was preserved. The remainder of the colony with queen and brood was taken by airplane and steamer to New York safely alive. Here they were turned over to Dr. Caryl P. Haskins for study but during his unavoidable absence at one time the entire colony died and was lost.</p></div>	https://treatment.plazi.org/id/492BA432F5A1BB7DB0001674E6DBBDED	Public Domain	No known copyright restrictions apply.
