ED3E5E1F457BFFBAFF75FF52FD3F6931.taxon	description	Mandible with basal border approximately equal chewing border, with broad and gently deep excision between basal and subbasal tooth. Anterior tooth of clypeus with lateral, almost indistinct, blunt denticle. Frontal carinae diverging posterad, maximum width between their outer edges about one fourth of head width. Compound eye small, with about 6 - 7 facets r. g. d., maximum diameter of compound eye smaller than oculomalar distance: total number of ommatidia less than 25, circa 20. Antennal scape fails to reach vertexal margin by not more than maximum scape width. Funnicular segment I as long as II-IV combined, segments II-VII distinctly broader than long, VIII as long as broad. Head with vertexal margin sligthly convex (f. f. v.). Mesosoma (p. v.) not forming an angle between dorsal and lateral surfaces of pronotum. Metanotal groove shallow to absent (p. v.), perceptible by difference in level of propodeum relative to promesonotal dorsum level. Basal face of propodeum round on side posteriorly with two small, obliquely oriented teeth. Declivous face laterally carinate. Petiole pedunculate, node antero-posteriorly not much compressed, nearly 2 / 3 as broad as postpetiole (d. v.); subpetiolar process mostly straight, anteriorly ending as a blunt and relatively small denticle (p. v.). Subpostpetiolar process subparallel to the ventrally projecting posterior socket. Examined material: ARGENTINA: Rosas, F. C. Sur, Buenos Aires Province, Juan B. Daguerre # 1904 [35 ° 57 ’ S, 58 ° 56 ’ W] (1 S lectotype, originally mounted on same pin with Solenopsis metanotalis var. picturata Santschi). Comments: The exclusive character of O. daguerrei workers in relation to all other species in the genus is the straight costulae on the frontal carinae that prolong caudad, attaining the vertexal margin but failing to laterally reach the compound eye, also the postpetiole (d. v.) is relatively narrower than of others species of the genus (Kempf, 1974: Figs. 05, 16 and 22). Only three specimens of O. daguerrei are known, all collected in the same locality in Argentina (Fig. 6), by Juan B. Daguerre. Sanstchi received them already mounted on the same pin with a worker of Solenopsis metanotalis var. picturata Santschi (# 1904, lectotype) and with a worker of Solenopsis tetracantha Emery (# 666). This association led Sanstchi to infer a close relationship between the mentioned species and Solenopsis. Note: we were not able to ascertain to which collection the code number in the types label refers to.	en	Albuquerque, Nicolas Lavour de, Brandão, Carlos Roberto Ferreira (2009): A revision of the Neotropical Solenopsidini ant genus OXYEPOECUS Santschi, 1926 (Hymenoptera: Formicidae: Myrmicinae). 2.

ED3E5E1F457BFFB9FD3AFA12FDBD6A4E.taxon	description	“ Ouvrière. Brun ferrugineux, membres plus clairs, tête, excepté les mandibules, et segment basal du gastre brun noirâtre. Tête mate, très finement réticulée, sur le front, le réticule se résout en fines stries et, sur les joues, le fond se montre luisant; épistome et mandibules luisants; corselet strié, les promésonotum en long, mais assez irregulièrement, l’épinotum transversalement et régulièrement. Poils longs et fins, pubescence presque nulle. La tête est de peu plus longue que large, si on ne compte pas la saillie que forme l’épistome avec ses dents; mais si on en tient compte, la tête est alors presque une fois et demie aussi longue que large. Les mandibules sont longues et armées de 4 grandes dents dont le basal est épaissé et séparée des autres. L’épistome est bicaréné et armé, comme dans M. vezenyii et M. rastratum. Le scape atteint presque le bord occipital; massue de 3 articles, le dernier plus long que les deux autres, ceux-ci presque égaux. Pas de suture promésonotale, le profil du corselet n’est presque pas impressioné dans la suture mésoépinotale; l’épinotum a la face descendante beaucoup plus courte que la face basale; cette dernière est droite, presque verticale, bordée d’une arrête sur les côtés, qui se termine en haut par une petite saillie mousse. Vu par-dessus, le pétiole paraît claviforme; de profil il est pédonculé et surmonté d’un noeud près de deux fois aussi haut que long; par-dessus, le noeud est un peu plus large que long; postpétiole ovale, à peine de moitié plus large que le noeud du pétiole – L. 3 mill ”. Comments: The characters that better distinguish O. mandibularis from other species in the genus are the workers’ relatively large overall size (3 mm) and the sculpture pattern on the head dorsum, promesonotum, and propodeum. However this species runs with O. rastratus in the identification key, but can be distinguished from it by the longer median tooth and the shorter lateral tooth in O. mandibularis.	en	Albuquerque, Nicolas Lavour de, Brandão, Carlos Roberto Ferreira (2009): A revision of the Neotropical Solenopsidini ant genus OXYEPOECUS Santschi, 1926 (Hymenoptera: Formicidae: Myrmicinae). 2.

Worker (Holotype and paratypes (N = 30), variation within brackets): t. l. = 2.08 (1.95 - 2,15); h. l. = 0.53 (0.50 - 0.53); h. w. = 0.40 (0.38 - 0.43); s. l. = 0.30 (0.28 - 0.31); m. l. e. = 0.06 (0.05 - 0.08); m. w. pr. = 0.25 (0.23 - 0.28); a. l. = 0.60 (0.58 - 0.60); h. f. l. = 0.33 (0.28 - 0.33); m. w. p. = 0.15 (0.13 - 0.18); m. w. pp. = 0.20 (0.18 - 0.20); c. i. 75 (76 - 81). Color chestnut brown, legs and antennae slightly lighter. Integument with irregularly reticulate sculpture covering almost all head dorsum, except close to clypeus, and around antennal insertions; almost all mesosoma, petiole dorsum and postpetiole with irregulary reticulate sculpture; gaster smooth and shining. Hairs relatively abundant, short, subdecumbent and curved mesad on head dorsum, and anteriorly curved on the head sides; long and suberect on dorsum of mesosoma, petiole and postpetiole; hairs on gaster decumbent and shorter. Mandible with basal border approximately equal chewing border, basal tooth separated from subbasal tooth by shallow diastema. Anterior tooth of clypeus with lateral, blunt denticle. Frontal carinae short, subparallel, with posterior end at level of anterior margin of compound eye, maximum width between their outer edges less than one fourth of head width. Compound eye very small, with 3 - 4 facets r. g. d.; total number of ommatidia not exceeding 7. Antennal scape fails to reach vertexal margin by distance greater than maximum scape width. Funnicular segment I longer than either VIII or IX, as long as II-V combined, segments II-VII distinctly broader than long, VIII and IX as long as broad. Head with vertexal margin straight (f. f. v.). Mesosoma with lateral and dorsal surfaces of pronotum not forming a well marked angle, slightly rounded. Metanotal groove weakly impressed (p. v.). Basal face of propodeum immarginate on sides, posteriorly with a small and obliquely directed tooth (p. v.). Declivous face laterally weakly carinate. Petiole pedunculate, node scarcely compressed antero-posteriorly (d. v.); subpetiolar process with anterior end as a small and obliquely oriented denticle. Postpetiole strongly compressed antero-posteriorly, not as high as petiolar node; subpostpetiolar process shaped as small, transversal crest, parallel to ventrally produced posterior socket of postpetiole. Gyne (variation of three paratype gynes): t. l. = (2.53 - 2.58); h. l. = (0.55 - 0.56); h. w. = (0.45 - 0.48); s. l. = (0.33 - 0.35); m. l. e. = (0.20 - 0.25); m. w. pr. = (0.43 - 0.45); a. l. = (0.70 - 0.73); h. f. l. = (0.38 - 0.40); m. w. p. = (0.18 - 0.20); m. w. pp. = (0.28 - 0.30); c. i. (81 - 86). Characters almost the same as workers, with the differences of the caste: the three ocelli with same diameter, approximately equal to minimum scape width, compound eye with 10 facets r. g. d., about 30 in all, scutellum not marginate.

Comments: The exclusive character of Oxyepoecus myops n. sp. workers in relation to the other species of the Rastratus group is the irregularly reticulate sculpture fully covering the head dorsum and almost all the mesosoma dorsum. Their compound eyes are the smallest in the genus. The distribution of O. myops n. sp. includes several Southern Brazil localities, and in Minas Gerais, São Paulo and Rio de Janeiro States. Workers of this species have been recently extracted from litter samples taken in localities at sea level and up to more than 1000 m high in the Serra do Mar Range. Most localities are covered by dense evergreen tropical forests, but in some cases, samples come from drier forests as well, as in Seara, SC and Teresópolis, RJ. In Serra da Cantareira, SP, workers were attracted to sardine baits set on the forest floor during the day.	en	Albuquerque, Nicolas Lavour de, Brandão, Carlos Roberto Ferreira (2009): A revision of the Neotropical Solenopsidini ant genus OXYEPOECUS Santschi, 1926 (Hymenoptera: Formicidae: Myrmicinae). 2.

Comments: In relation to the Oxyepoecus Rastratus species-group, O. plaumanni workers present exclusively the costulate sculpture between the frontal carinae, which do not reach the vertexal margin or laterally the compound eyes (Kempf, 1974: Figs. 27, 28, 29 and 30). In the original description, Kempf (1974) cited a paratype from Brazil, Rio Grande do Sul state, Tainhas [29 ° 16 ’ S, 50 ° 18 ’ W], collected in April. 1959, by F. Plaumann, (W. W. K. # 3247). However, although the pin and label are preserved in the MZSP collection, the specimen is missing from the triangle. We were not able to locate coordinates for Linha Facão, SC. The distribution of O. plaumanni includes only localities at South and São Paulo State at Southeastern Brazil (Fig. 7), both in dense evergreen and drier forests.	en	Albuquerque, Nicolas Lavour de, Brandão, Carlos Roberto Ferreira (2009): A revision of the Neotropical Solenopsidini ant genus OXYEPOECUS Santschi, 1926 (Hymenoptera: Formicidae: Myrmicinae). 2.

Brazil: São Paulo: Salesópolis [23 ° 39 ’ S, 45 ° 53 ’ W], 20 - 26. x. 1997, C. Klingenberg & C. I. Yamamoto col., attracted to sardine baits; deposited in MZSP. Paratypes (all from Brazil): São Paulo: forty one workers and two gynes from Salesópolis (Same locality of the Holotype, but collected in different dates and by different collectors); 33 workers and 2 gynes deposited in MZSP, one worker deposited in AMNH, one worker deposited in CASC, one worker deposited in CECL, one worker deposited in CPDC, one worker deposited in ICNC, one worker deposited in LACM, one worker deposited in MIZA, one worker deposited in USNM. Etymology: we are pleased to dedicate this species to our friend and colleague, Rogério Rosa da Silva, the most efficient collector in our team. Worker (Holotype and paratypes (N = 33) variation within brackets): t. l. = 2.33 (2.30 - 2,40); h. l. = 0.60 (0.60 - 0.63); h. w. = 0.45 (0.43 - 0.48); s. l. = 0.35 (0.35 - 0.38); m. l. e. = 0.10 (0.10 - 0.13); m. w. pr. = 0.33 (0.30 - 0.35); a. l. = 0.65 (0.65 - 0.68); h. f. l. = 0.35 (0.35 - 0.38); m. w. p. = 0.20 (0.20 - 0.23); m. w. pp. = 0.25 (0.25 - 0.28); c. i. 75 (72 - 76). Color chestnut brown, gaster fuscous. Irregularly costulae and rugulate sculpture covering almost all head dorsum integument, except by clypeus, around antennal insertions and vertex; almost all mesosoma irregularly reticulate, except antero-lateral portion of pronotum, area around propodeal spiracle, petiolar peduncle dorsum, node of petiole and postpetiole smooth and shining. Hairs moderately abundant, short and subdecumbent, on head dorsum mesad oriented, anteriorly curved on head sides; dorsum of mesosoma with suberect hairs, backwards oriented on petiolar and postpetiole nodes; gaster without interspersed shorter and decumbent hairs. Head as in Fig. 5 a (f. f. v.): Mandible with basal border slightly shorter than chewing border, basal tooth separated from subbasal tooth by shallow diastema. Anterior tooth of clypeus mesially directed with smaller lateral denticle. Frontal carinae gently convex and subparallel over antennal sockets, maximum width between outer edges always less than one fourth head width. Compound eye with 4 - 5 facets r. g. d., height less than oculomalar; total number of ommatidia not exceeding 13. Antennal scape fails to reach vertexal corner by distance approximately equal to maximum scape width. Funnicular segment I longer than II-V combined, segments II-VII distinctly broader than long, VIII and IX as long as broad. Vertexal margin straight. Mesosoma with promesonotum gently rounded on shoulders. Metanotal groove almost indistinct (p. v.). Basal face of propodeum immarginate on sides, posteriorly with a small tooth. Declivous face laterally weakly carinate. Petiole pedunculate, node scarcely compressed antero-posteriorly (d. v.) club shaped; subpetiolar process with a small, blunt and obliquely oriented denticle anteriorly. Postpetiole very broad, not as high as petiolar node; subpostpetiolar process shaped as small, transversal crest. Gyne (variation of gynes paratypes, N = 2): t. l. = (2.80 - 2.93); h. l. = (0.60 - 0.63); h. w. = (0.50 - 0.53); s. l. = (0.40 - 0.43); m. l. e. = (0.25 - 0.30); m. w. pr. = (0.43 - 0.45); a. l. = (0.70 - 0.73); h. f. l. = (0.38 - 0.40); m. w. p. = (0.18 - 0.20); m. w. pp. = (0.33 - 0.35); c. i. (83 - 85). Almost same workers character states, with caste differences of: three ocelli very small, with same diameter, approximately half minimum thickness of antennal scape, compound eye with 8 facets r. g. d., and circa 40 in whole eye. Male: Unknown. Comments: In the Rastratus species-group, O. rosai workers present the integument of mesopleuron and lateral pronotum irregularly sculptured, as in O. myops, but differs from the later by the larger compound eyes, and by the smooth integument on the head vertex and lateral portions of the pronotum, petiolar node, and postpetiole. The distribution of O. rosai includes only localities at South and Southeastern Brazil, between São Paulo and Santa Catarina States (Fig. 8). The specimens were attracted to sardine baits or recovered from the leaf-litter using Winkler extractors. Examined material: BRAZIL: Paraná: Tunas, Parque das Lauráceas, 21 - 29. ii. 2001, [R.
