Adelomyrmex striatus Fernandez HNS NEW SPECIES (Figs. 37, 74)
Worker measurements (Paratype). HL 0.58 HW 0.51 SL 0.38 EL 0.08 WL 0.53 GL 0.66 TL 2.13 CI 88 SI 75.
Worker diagnosis: Mandibles with slightly oblique masticatory borders, with 5 teeth decreasing in size from the apical teeth, the last two poorly defined. Clypeus short. Dorsum of clypeal plate with two curved ridges prolongued into frontal carinae. Clypeal tooth of the anterior clypeal margin not ready visible in full face view. Eyes small, with approximately14 facets. [Hypostomal tooth not observed]. Promesonotum strongly convex; metanotal groove feebly impressed. Propodeum sloping with two very short spines, reduced to small triangles. Propodeal lobe subtriangular, evenly rounded. Petiole and postpetiole stout, massive. Node of petiole subquadrate, with anterior and posterior faces slightly sloping to apex which is slightly convex. Venter of postpetiole with two transverse ridges, the anterior one more developed, in profile looking as teethlike projections; dorsal surface as in petiolar node. Head, pronotum and mesonotum longitudinally striate. Sides of mesosoma and petiole longitudinally striate. Dorsal face of propodeum, petiole and postpetiole transversely striate. Postpetiole obliquely striate. Anterior side of petiole and posterior side of postpetiole transversely striate. Mandibles smooth to with longitudinal rugae feebly marked in the outer half. Mandibles, legs and gaster smooth and shining. Hairs yellowish, long and flexuous on the body, some very long, more short and apressed on antennae and legs. Few long hairs on hind femora. Head and thorax brown, gaster light brown, antennae and legs yellowish.
Material examined: 1 w, paratype, BRASIL: Amazonas, Igarape , Marianil, R. Branco, Rov. Km 25 NE Manaus , 22.viii. 62, W.L. Brown Jr. leg. M-13 ( MZSP). Holotype worker, same locality, seen but not measured. Both deposited in MZSP. In the MZSP there are also a teneral worker of this species.
Comments. I have followed the name and designation of type material as labeled by the late W. W. Kempf, who discovered this new species, even though I didn’t find the manuscript notes of A. striatus HNS in the archives of MZSP. This species is readily separated from congeners by the conspicuous longitudinal striation, very short propodeal spines, and subquadrate petiole and postpetiole.
