TL;DR: A genus and species of Myrmicinae certainly very unlike any ants previously described, and that they could not reasonably be included in any living formicid tribe so far known.
Abstract: The two remarkable ant specimens we describe below were sent to us originally by Mr. R. R. Snelling of the Los Angeles County Museum of Natural History in California. After prolonged study, we concluded that they represent a genus and species of Myrmicinae certainly very unlike any ants previously described, and that they could not reasonably be included in any living formicid tribe so far known. True, this new ant shares some striking habitus characters with certain Dacetini (Glamyromyrmex , Gymnomyrmex) ,

TL;DR: The queen’s thickened scape base and the largely smooth and shining alitrunk with overhanging scutal margins, are "protective" characters suggesting social parasitism as a way of nest-founding for this caste.
Abstract: _A_ number of ants have plug-shaped heads, known or assumed to be used to stopper the nest entrance. This phenomenon, called phragmosis, is best understoo.d in certain groups o.f Camponotus and Cephalotini (e.g. Wheeler I9IO: 209-212 Szabd-Patay I928 Creighton and Gregg 954), but Wheeler (I9OI: 534; 1927) also, described species with phragmotic-like heads in Pheidole, Crematogaster and the dacetine genus Colobostr,uma, while Patrizi (I948) published the problematical Solenopsis (Crateropsis) elmenteitae (placed by Ettersha.nk, 1966, in Oligomyrmex). In most of these forms, either the queens or the soldiers, or both, are the phragmotic castes; in Colobostruma leae, the assumed phragrnotics are the queen and the monomorphic workers. In the new species of Pheidole described below, phragmotic behavior at some stage of the life cycle is indicated only or t’he queen caste, and even then is inferred from her aberrant body form. But in this case, the plug is tormed, not by the head, but by the highly mo.dified gaster (Figs. 6 and 7). Two queens showing this plug-like modification of the gaster were taken separately trom rotten wood in rain to.rest in the. general vicinity of Manaus during my collecting trip of I962 in the Brazilian Amazon. In one case, a.nd possibly in both, the queens belonged to definite colonies with workers, soldiers and brood. (Notes on collection M-6o are ambiguous because two Pheidole queens, one of embolopx and one o.f a to.tally different species, were in the vial with this number, but the notes state that \"the\" queen was taken apart from the soldiers, workers and brood. Probably one of the two queens was taken up in the aspirator along with bits of rotten wood without my knowing it.) The queen’s thickened scape base (with a gelatinous sheath) and the largely smooth and shining alitrunk with overhanging scutal margins, are \"protective\" characters suggesting social parasitism as a way of nest-founding for this caste. The strong similarities in color, sculpture and pilosity between the queens and the accompanying

TL;DR: Orectognathus rostratus sp.
Abstract: Orectognathus rostratus sp. n. is described from Eastern Australian rain forest. It is placed confidently in the genus Orectognathus Smith, despite superficial resemblances to the related genera, Arnoldidris and Epopostruma.
TL;DR: Variations of the venation of fore wings, and the genital armature of the male are studied and the female and themale are described.
Abstract: Tetraponera anthracina est une fourmi de la sous-famille desPromyrmicinae, nidifiant dans des branches mortes.Santschi revela cette espece par une description sommaire de l'ouvriere en 1909. Nous precisons cette diagnose et decrivons les sexues. Les variations de la nervation alaire et les genitalia du mâle sont egalement etudies.
