Etymology. This species was named in honor of Edmund Reitter (1845–1920), an Austrian Entomologist specialist in Coleoptera   who collected this species’s type specimens.

Comments. Kempf (1960) described the queen of H. reitteri   and labelled it as a paratype. However, this queen is not part of the type specimens. The first queen description was made by Forel (1912) in the original description of Pogonomyrmex goeldi   . Also, Kempf (1960) indicated that five H. reitteri   syntypes from “an unknown locality in São Paulo State” were housed at Naturhistorisches Museum Wien, Austria. While visiting this collection at the museum, we recognized two workers and one queen with the label data described by Mayr (1887), and later labelled as lectotypes (workers) and paratype (queen) by Kempf. At the same museum there is also one worker labelled “ Brazil ” and “ lectotype ”, and two workers from Santa Catarina, Brazil, labelled “ paratypes ” by Kempf. Nevertheless, as Mayr (1887) described only the worker, providing a range of body measures and stated that the type locality was São Paulo, Brazil, we understand that only the two workers with the label data similar to what was described by Mayr are part of this type series. Possibly the other three “ syntype ” workers seen by Kempf have been misplaced. Kempf did not publish the later type designations he had apparently intended, thus we are designating the lectotype and consequently the paralectotype. Therefore, any other specimen with a type label should not be considered as such.

Hylomyrma reitteri   is similar to H. balzani   , H. lopesi   , H. transversa   , and H. wachiperi   . The first four species show broad distributions ( Figs. 84 View FIGURE 84 , 85 View FIGURE 85 , 89 View FIGURE 89 ), while H. wachiperi   is known only in one locality in Peru ( Fig. 86 View FIGURE 86 ). Hylomyrma reitteri   , H. transversa   , and H. wachiperi   are allopatric, but present the discontinuous dorsal margin of petiole, and a similar pattern of sculpturation on head. However, H. reitteri   can be easily distinguished from H. transversa   (characteristic in parentheses) in the reniform eye (vs. drop-shaped), the longitudinal striae on the mesonotal dorsum (vs. transverse striae), and the smooth ventral surface of petiole (vs. striate). Hylomyrma reitteri   differs from H. wachiperi   in the reniform eye (vs. oval), the smooth ventral surface of petiole (vs. striate), and the tergum of the first gastral segment with short striae (vs. long striae).

Hylomyrma balzani   and H. reitteri   occur in sympatry in Paraguay (Alto Paraná department) and in 19 localities at Brazil (Santa Teresa, ES; Lavras, and Viçosa, MG; Estrada Velha Guaricana, Irati, Laranjeiras, Morretes, Rondon, and Tuneiras do Oeste, PR; Rio de Janeiro, and Teresópolis, RJ; Frederico Westphalen, Nova Petrópolis, and 5km N of Progresso, RS; Chapecó, Nova Teutônia, and Seara, SC; Botucatu, and Jundiaí, SP). Hylomyrma reitteri   can be distinguished from H. balzani   by the regular to irregular striae on the mesosoma (vs. rugose striae), the irregular striae on the petiole (vs. rugose striae), and the smooth ventral surface of petiole (vs. striate surface). The winged queens of both species are very similar, differing only in the laterodorsal sculpture of the propodeum. In Hylomyrma balzani   this region presents rugose striae, whereas H. reitteri   has regular to irregular striae in this region.

Hylomyrma reitteri   differs from H. lopesi   in the smaller body size (vs. larger), the thick striae on the mesosomal dorsum (vs. thin striae), the transverse striae on the ventral surface of petiole (vs. smooth surface), the laterals of the mesosoma covered mainly with regular and thick striae that are directed to the propodeal spine (vs. irregular and thin striae directed to the propodeal dorsum), and the striate subpostpetiolar process (vs. smooth). Both species occur broadlly in Brazil, the distribution of H. reitteri   is more restricted to eastern portions of Brazil from southern and southeast regions, whereas H. lopesi   is distributed mainly in the center of Brazil from northern (state of Pará) to southern (state of São Paulo) regions. Hylomyrma reitteri   and H. lopesi   co-occur in Botucatu (SP), Niquelândia (GO), and São José de Buerarema (BA), Brazil.

The most striking intraspecific morphological variation found in H. reitteri   concerns the pilosity and the sculpture of the petiolar dorsum. The striae on the petiolar dorsum, usually longitudinal, can be transverse (Brigadeiro, MG, and Teresópolis, RJ, Brazil) or can be in part longitudinal and in part transverse (Niquelândia, GO; Brigadeiro, MG; Santa Teresa, ES; and Morretes, PR, Brazil). Hylomyrma reitteri   setae are mostly branched, with branches of unequal length. The exception to this setae pattern is observed in some specimens from Florianópolis, SC and Viçosa, MG, Brazil, which present mostly unbranched setae, and the few branched setae have branches of equal size (found in the propodeum, petiole, postpetiole and/or gaster).

It is impressive that out of the 1,037 H. reitteri   female specimens analysed, 730 are intercastes. As in H. balzani   and H. lopesi   , H. reitteri   presents considerable morphological variation among intercastes. We recognized eight morphotypes that essentially have larger body sizes, and mostly are worker-like, just two are queen-like ( Fig. 2A View FIGURE 2 ).

Distribution. This species is widely distributed in eastern Brazil, from southern Bahia to Rio Grande do Sul. It also occurs in Paraguay (Salto Tembey and Ciudad del Este) ( Fig. 85 View FIGURE 85 ).

Natural history. Hylomyrma reitteri   inhabits mainly areas in the Atlantic forest, but there are also records in the “Cerrado” (Brazilian savanna) in Goiás, and in coffee plantations (Minas Gerais), both in Brazil. Specimens are frequently found in leaf-litter samples ( Fig. 68 View FIGURE 68 ), which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers. Most of the intercastes are worker-like and just few have more queen-like traits, those may in the future be understood as ergatoids. One winged queen and one queen-like intercaste were collected together in two different winkler samples (winkler 49 from São Bonifácio, SC, and winkler 31 from Santa Teresa, ES, Brazil).

Large-sized. Color, pilosity, and some sculpture characters shared with conspecific workers, only slightly larger. Larger diameter of eye with 16 ommatidia. Longitudinal, irregular, slightly anastomosed striae on scutum going from an anterior central point towards transcutal suture, interspaces distinguishable. Longitudinal striae with interspaces distinguishable on anepisternum and katepisternum, mostly irregular and anastomosed on anepisternum and regular on katepisternum. Axilla with mostly anastomosed striae, striation inclinated to anteroposterior body axis. Scutoscutellar sulcus inconspicuous. Mostly vermicular striae on scutellum. Transverse striae on propodeum (DV). Lateral of mesosoma and laterally with irregular to vermicular striae directed to propodeal spine, interspaces distinguishable. Wings unknown. MALE Unknown.

Etymology. Sagax (Latin)   = wise, sagacious.

Comments. This species is similar to H. virginiae   and H. mitiae   in the vermicular sculpture on the head dorsum and mesosoma, and the anastomosed striae on the postpetiole and first gastral tergite. Hylomyrma sagax   is distinguished from H. virginiae   (characteristic in parentheses) based on the following characters: a pair of large teeth laterally at the clypeus anterior margin (vs. a pair of medium teeth), the propodeal spine comparatively longer and needle-like (vs. shorter and thicker), and the continuous dorsal margin of petiole (vs. discontinuous). Hylomyrma sagax   is distinguished from H. mitiae   in the pair of large teeth laterally at the clypeus anterior margin (vs. medium teeth), the presence of smooth interspaces between the vermicular striae on the entire mesosoma (vs. smooth interspaces only on the mesosomal dorsum; the lateral of mesosoma is covered with very thin striae with indistinguishable interspaces), and the convex subpostpetiolar process (vs. subtriangular). All three species are allopatric; Hylomyrma sagax   is restricted to southeast Colombia ( Fig. 83 View FIGURE 83 ), whereas H. mitiae   occurs in French Guiana ( Fig. 87 View FIGURE 87 ), and H. virginiae   is recorded in Ecuador (both sides of The Andes) and in western Colombia ( Fig. 89 View FIGURE 89 ).

Distribution. This species is only known from southeast Colombia ( Fig. 83 View FIGURE 83 ).

Natural history. Only one worker is known, apart from the type specimens. All material examined was collected from leaf-litter of tropical rainforest, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers.

Additional material examined (1 worker): COLOMBIA: Caquetá: [Puerto] Solano, PNN [Serranía de] Chiribiquete, R. Sararamano, B. Verde military , 300m, 0°10′48″N, 72°37′24″W, Winkler 14, 9.iv.2000, E. González leg. (1W covered with gold) [ IHVL] GoogleMaps   .
