TYPE MATERIAL: BRAZIL: Bahía: Centrurus barythenar: 12 ♂ syntypes (NMW 2248), Joazeiro. Centrurus stenochirus: 2 ♂, 1 juv.? ♀ syntypes (NMW 2251), Barra. Ceará: Rhopalurus rochae: Lectotype ♀, paralectotype ♂ [desig. Lourenço, 1982 a: 138] (MIZT Sc 421 ex 645), Fortaleza.
DIAGNOSIS: Jaguajir rochae can be differentiated from J. agamemnon and J. pintoi by its paler coloration and more slender metasoma. Whereas the base coloration is pale to dark yellow, and the metasoma of the male slightly wider posteriorly in J. rochae, the base coloration is brown to black, and the metasoma of the male markedly wider posteriorly in J. agamemnon and J. pintoi. Additionally, 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, whereas 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. Furthermore, the subaculear tubercle of the telson is much reduced, forming a small protuberance in J. rochae, as in J. pintoi, but well developed and spinoid in J. agamemnon.
DISTRIBUTION: Jaguajir rochae is endemic to northeastern Brazil and recorded from the states of Bahía, Ceará, Paraíba, Pernambuco, Piauí, Río Grande do Norte and Sergipe (fig. 8). A record from Costa Rica (Viquez, 1935) is based on a misidentification.
ECOLOGY: This species inhabits open savannah (fig. 2D). Specimens collected by the authors 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: Borelli (1910) named the species after Francisco Diaz da Rocha, but the original spelling was feminine, rochae. Fet and Lowe (2000) noted that the masculine spelling is rochai and changed it accordingly. Although the corrected spelling has been adopted by others (e.g., Teruel, 2006: 52), we consider it an unjustified emendation and continue to use Borelli’s (1910) original spelling. It is noteworthy that, on the page preceding the description of R. rochae, Borelli (1910) described Tityus duckei Borelli, 1910, after Mr. Ducke, implying he was aware of the proper ending for a masculine name and it was not a lapsus. If Rocha is considered a Latin name, the proper ending, even if dedicated to a man, is rochae (ICZN, 1999: Art. 31.1.1. Examples), which may be what Borelli (1910) intended.
