Palpal formula 1,1. Mandible triangular; dorsum convex, with mild sculpturing; masticatory margin with 10 teeth in the outer row and 3 on the inner row (see figure 1 of Longino, 2013 for a detailed description of these specialized teeth); teeth 2, 7 and 10 (apical) of the outer row slightly longer and sharper than the remaining; inner teeth originating at the same level of teeth 3–6 of the main row; most or all teeth of the outer row with minute, serial V-shaped grooves along their individual height; dorsal surface covered on ground pilosity similar to that of head, denser basolaterally, apically the ground pilosity is thinner and sparser; inner surface concave, smooth on the blade area and reticulate basally; carina between lateral and inner surfaces long and having a simple long seta basally. Anterior clypeal margin concave medially; dorsum of clypeus with rough and opaque sculpturing; epistomal sulcus a deep groove which makes the clypeus surface and the frontal lobes convex. Anterior third of frontovertex with similar sculpturing to that of clypeus; in the remaining frontovertexal area, sculpturing is punctate with superimposed rugulae; longitudinal medial carina mild. Posteriormost surface of vertex (not seen in full face view, best seen in posterior view of the head) punctate only; occipital carina not entire, marked only dorsomedially, barely visible in full-face view.

Scrobe deep, sharply delimited, its inner surface mostly smooth with a few rugulae. Antenna socket deep, reticulate, interrupting anterior section of dorsal margin of the scrobe. In lateral view, the lateral clypeal margin is seen as a carina that is adjacent to the ventral portion of the antennal socket margin and fades at about the middle of the scrobe surface, anterior to the eye level. Compound eye small, with 6–11 ommatidia. In full-face view, lateral margin of head posterad the eye with two sharp angles, a lateral vertexal angle and a posterior vertexal angle, which form a quadrate vertexal protruded corner; posterior vertexal margin between the vertexal corners concave. Ventral surface of head punctate with superimposed rugulae, covered on ground pilosity of similar size and type to that of scape and having a few long, simple suberect setae posteromedially.

Descending propodeal surface reticulate. Lower mesopleuron obliquely divided by a carina which separates an elevated lower portion from an upper portion which is contiguous with the rest of the pleural surface. Ground pilosity on mesosoma restricted to dorsum of promesonotum, where it is thinner than that of head, and around the anterolateral margin of the pronotal disc, where it as developed as that on head.

Dorsum of petiole node slightly broader than long, dorsum of postpetiole about twice as wide as long. In profile, petiole with a mildly concave sternal region; subpetiolar process anteroventrally inclined, fingerlike, often entirely hidden by propodeal lobe. Petiole flanked laterally by two pairs of carinae, one marking the peduncle dorsolateral corners and the other crossing the entire length of the petiole ventrad the first pair. In lateral view, node taller anteriorly, delimited by carina only posteriorly. In dorsal view, postpetiole crescent-shaped, with a pair of posterior mediolateral tumuli; sternal region with a pair of stiff setae anterolaterally. First gaster segment transversely delimited by carinae anteriorly (anterior margins of tergite IV and sternite IV, respectively). Sternite IV longitudinally mildly keeled medially. Metasoma overall punctate; surface in between punctae on the dorsum of postpetiole and gaster considerably shiny, contrasting with the petiole which is more opaque in overall appearance as punctation is denser, with little space between punctae. Specialized, large, pompon-like setae on body as follows: full complement of 9 pairs on vertex; 4 pairs on the promesonotum (a pair anteromedially and a pair posterolaterally on the assumed pronotal area and a pair anterolaterally and a pair posterolaterally on the assumed mesonotal area); petiole with one pair flanking the posterolateral edges of the node; postpetiole with a pair posterolaterally and another pair mesad to that, on the apex of the postpetiole tumuli; first gaster tergite with a medial row of 4 pairs, flanked laterally by another pair just posterad the third of the medial line and another pair even more laterally positioned, at the level of the fourth medial pair.

Head widens posteriorly from lateral clypeus to compound eyes. Compound eye strongly bulging. Vertexal corners, although round, considerably distinct; middle section of vertexal margin evenly convex. Mandible triangular, its dorsal surface shallowly reticulate basolaterally; masticatory margin with 3–4 teeth. Labrum distal margin with small lobes separated by a medial concavity; apical margin with simple setae. Palpal formula 1,1. Frontal carina bifurcated posteriorly. Frontal lobe dorsally protruded, separated from posterior clypeal margin by a minor oblique carina. In posterior view, scape axis bent; its anterior edge convex; pedicel slightly shorter than scape; antennomeres 3–13 with abundant semierect small, simple setae, antennomeres clearly getting shorter from 3–12; apical the longest in antenna. Dorsum of head reticulate with a few scattered small rugulae, mainly around the eye. Mesosoma. Notauli anteriorly deep, with a few transversal carinae along its axis, posteriorly much shallower and without carinae. Mesoscutum strongly reticulate with sparse rugulae; parapsidal lines and transcutal line well-marked; deep and scutoscutellar suture, with small transversal carinae along its axis. Scutellum reticulate trapezoidal, with superimposed rugulae, a posteromedial longitudinal carina meets the posterior edge. Pleural sculpturing reticulate all through, except for upper portion of lower mesopleuron and lower portion of upper mesopleuron, which are smooth. Mesopleuron separated from metapleuron by thin suture; upper metapleuron separated from lateral propodeum by deep sulcus; lower metapleuron merged into lower lateral propodeum. Propodeal spiracle strongly raised from cuticle. Propodeal spine triangular, subtended by thin lamella. Wings slightly infuscated. Metasoma. Petiole node dome-shaped, poorly defined, without carinated edges; dorsum of node almost smooth medially; subpetiolar process finger-like, anteroventrally directed. Postpetiole tergite mostly smooth, except for reticulate borders; sternite with a pair of lateral simple, small setae, as in workers. Gaster almost entirely smooth, except for shallow and inconspicuous sculpturing on the borders of the sclerites; tergite IV and sternite IV (first gastral segment) transversely carinated on their anterior and edges, stronger carina on the tergite. Sternite IX subtriangular; paramere finger-like; volsellar digitus L-shaped with peg-like setae on the apex, cuspis a short lobe with simple, thin setae; penisvalve serrated margin slightly sinuous. Setation. stand setae on body of simple, flexuous or some slightly thicker to spatulate with frayed apex. These thicker setae form defined pairs close to end of the frontal carina (2 pairs), the vertexal margin (3 pairs), anterolateral pronotum (1 pair, the “humeral pair”), some on the mesoscutum and mesoscutellum, a pair posterolaterally on the petiole and a pair, the thickest, laterally on the postpetiole. Coloration. Black, except for dark brown antennae and light brown legs.</p> <p>Comments. Characters justifying the separation of E. gravis from E. reichenspergeri were provided above and are illustrated (Table 1, Figs. 1 and 2, E. xibalba also included for comparison). The lectotype of E. reichenspergeri (Fig. 9) from the state of Santa Catarina, Brazil, is not in optimal preservation, but the diagnostic characters are evident and it could be matched satisfactorily with the workers from Minas Gerais.</p> <p>An uncommon state for E. gravis was observed in one specimen (Fig. 1, D, red circle). It has an additional mesosomal standing seta that was considered an exception and not representing the common state for the species. The seta is too close to the posterolateral promesonotal seta; usually when Eurhopalothrix species have two pairs of setae on the posterior half of promesonotum (the corresponding mesonotal area), the anterior pair is located more anteriorly than what was observed in that specimen. The presence of this anomalous seta shows the importance of determining not only the number of pairs, but their exact position of origin on the sclerite surface.</p> <p>Geographic range.

Scutellum reticulate with superimposed rugulae, roughly trapezoidal, but with bilobed posterior margin.

Propodeal spiracle raised from cuticle. Propodeal spine triangular, subtended by thin lamella, both somewhat spongious and translucid. Wings hyaline. Metasoma. Petiole node in profile with poorly defined anterior and dorsal margins and well-defined, carinated, dorsal and posterior margins; dorsal surface of node smooth. Subpetiolar process small, finger-like, anteroventrally directed. Postpetiole tergite mostly smooth, except for reticulation posterolaterally; sternite with a pair of lateral simple, flexuous setae (longer than the pair present in workers). Gaster first tergite and sternite anteriorly carinated, gaster entirely smooth and shiny.</p> <p>Pilosity. Body covered mostly on simple and flexuous setae, some only slightly thicker with frayed apex, never developed as spatulated or remiform. The thicker setae form defined pairs in between eye and frontal carina (1 pair), medially on vertex (at least 2 pairs), laterally on occipital carina (1 pair), some on the mesoscutum and mesoscutellum, and laterally on the postpetiole (1 pair).</p> <p>Color. Overall dark brown to black, except for dark brown mandibles and antennae (mostly) and light brown legs (except for coxae which are darker) and apex of antennae.</p> <p>Comments. This male morphospecies occurs in Viçosa, Minas Gerais, Brazil, where three Eurhopalothrix species are known by the females: E. bruchi, E. reichenspergeri and E. spectabilis. Eurhopalothrix ufv-01 is likely the male of E. spectabilis for sharing with the females the following traits (although not manifested in the male in the exact same way as in the females): labral apical margin without prominent lobes; scape lobe relatively large; propodeal lamella translucid; and posterior margin of petiole node with a marked carina.</p> <p>Eurhopalothrix ufv-01 differs from the male of E. reichenspergeri by the concave masticatory margin of the mandible, as opposed to a marked toothed margin; a translucid, very thin border of the clypeus, as opposed to a thicker (still translucid) band along the clypeal margin; a more strongly lobate anterior scape margin; the compound eyes not bulging conspicuously; the vertexal corners slightly less pronounced; a smooth rather than reticulate lower metapleuron; a more developed and whitish/spongious propodeal lamella rather than a thinner and darker one; the ventral petiole margin more straight as opposed to having a wavy margin; the petiolar node posteriorly transversely carinated; the postpetiole pair of posterolateral stand setae thinner than in E. reichenspergeri, which is strongly spatulate (Fig. 15).</p> <p>There are no images of the male of E. gravis, which was described by Mann (1922). Through the description alone, a trait which can be highlighted as an important difference between E. gravis and E. reichenspergeri males is the mandible having a concave masticatory margin (“blades strongly concave” in Mann, 1922) in the former as opposed to dentate in the latter.</p> <p>The male of E. floridana Brown &amp; Kempf, 1960 has been described (Deyrup et al.,1997) and images of one specimen are available on Antweb (CASENT0103905, images by April Nobile). It has a concave masticatory margin, barely forming an apical tooth (similar to Eurhopalothrix ufv-01); the vertexal margin is without marked vertexal corners (similar to Eurhopalothrix ufv-01); it lacks thickened setae on most of the body, but it does have a pair of spatulate setae laterally on postpetiole. The only smooth pleural regions are the lower and upper mesopleura (similar to E. reichenspergeri). It lacks a propodeal spine (differing from E. gravis, E. reichenspergeri and Eurhopalothrix ufv-01 in that respect), but has a thin propodeal lamella. It apparently has a poorly developed subpetiolar process and the petiole node does not have a posterior transversal carina (similar to E. reichenspergeri). The wings are slightly infuscated (similar to E. gravis and E. reichenspergeri). It seems to be overall smaller than E. reichenspergeri and similar in size to Eurhopalothrix ufv-01, as the size of forewing indicates (2.32–2.45 mm in E. floridana).</p> <p>Examined material.
