DIAGNOSIS: Jaguajir agamemnon is most closely related to J. pintoi. The two species resemble one another, and differ from J. rochae, in their darker coloration and broader metasoma. Whereas the base coloration is brown to black, and the metasoma of the male markedly wider posteriorly in J. agamemnon and J. pintoi, the base coloration is pale to dark yellow, and the metasoma of the male slightly wider posteriorly in J. rochae. Additionally, the fixed and movable fingers of the pedipalp chela of the male are markedly curved, creating a large proximal gap between them, and the proximal lobe on the fixed finger of the male is reduced or absent in J. agamemnon and J. pintoi, whereas the fixed and movable fingers of the pedipalp chela of the male are slightly curved, creating a small proximal gap between them, and the proximal lobe on the fixed finger of the male exhibits a prominent proximal lobe, in J. rochae. Furthermore, the subaculear tubercle of the telson is well developed and spinoid in J. agamemnon, but very reduced, forming a small protuberance, in J. pintoi and J. rochae.
Jaguajir agamemnon can be further differentiated from J. pintoi as follows. Jaguajir agamemnon is bicolored and generally paler, with the prosoma and tergites I–VI brown and tergite VII, metasoma, telson, pedipalps, and legs lighter, somewhat orange, whereas J. pintoi, is almost uniformly dark, with the prosoma, tergites, metasoma, telson, and pedipalps dark brown to black, and the sternites, legs, and telson somewhat lighter, reddish brown. Additionally, the metasoma of J. agamemnon is proportionally more slender, with metasomal segment V approximately 1.5× longer than wide, than that of J. pintoi, with metasomal segment V almost as wide as long. The dorsolateral carinae of the metasomal segments comprise small, acuminate granules in J. agamemnon, whereas the carinae comprise blunt spiniform granules, increasing in size posteriorly, especially prominent on segments III and IV, in J. pintoi.
DISTRIBUTION: Jaguajir agamemnon is endemic to northeastern Brazil and recorded from the states of Bahía, Ceará, Goiás, Maranhão, Mato Grosso, Pernambuco, Piauí, and Tocantins (fig. 7).
ECOLOGY: This species inhabits open savannah. Personally collected specimens were found under stones during the day and with UV light detection at night. The habitat and habitus are consistent with the lapidicolous ecomorphotype (Prendini, 2001 b).
REMARKS: The evidence and analyses presented by Esposito et al. (in review) demonstrated that R. acromelas is conspecific with J. agamemnon, justifying its synonymy, and that of its former synonyms, with the latter, resulting in the following new synonyms: Rhopalurus acromelas Lutz and Mello, 1922 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.; Rhopalurus melleipalpus Lutz and Mello, 1922 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.; Rhopalurus iglesiasi Werner, 1927 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.; Rhopalurus lambdophorus Mello-Leitão, 1932 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.; Rhopalurus dorsomaculatus Prado, 1938 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.; Rhopalurus goiasensis Prado, 1940 = Jaguajir agamemnon (C.L. Koch, 1839), syn. nov.
