Holotype. Female. BRAZIL: Guanabara [=?; oceanic bay in southern Brazil with Rio de Janeiro on its western shore or a former Brazilian state that existed from 1960 to 1975, now Rio de Janeiro], Represa Rio Grande, February 1968, M. Alvarenga (AEIC, paratype of L. varius).
Diagnosis. Liosphex guanabara is unique among all Liosphex in the combination of the following characters: Anterior margin of pronotum with median notch (as in Fig. 19); mid- and hindtibia without a group of stout and thick bristles (as in Fig. 22) and scutellum, metanotum and tergite I completely black (Fig. 43).
Description of the female. Head (Fig. 41): Maximum width in frontal view 1.5 mm. UID 1.7× LID. Flagellomeres short (flagellomere II 3.0×, flagellomere VII 1.85× as long as wide). Apical bristles present on flagellomeres I–V, longer bristle on flagellomere I 1.1× its length. OOD 2.0×, IOD 1.1×, MOD 1.0× LOD.
Mesosoma: Length of mesosoma: 2.6 mm. Anterior margin of pronotum with median notch (as in Fig. 19). Streptaulus in lateral view curved.
Wings: Maximum length of forewing: 5.5 mm, 2.1× as long as mesosoma; forewing 1cu-a distad by M by 2.0× its length. M-cu distinctly curved. 1Rs 2.4× as long as high, its basal angle clearly smaller than 90° (Fig. 9).
Legs: Forebasitarsomere short, length of antennal cleaner 0.35× its length. Mid- and hindfemur with a few bristles spread over its distal dorsal area. Hindtibia with two bristles on only one side of insertion of shorter apical spur (as in Fig. 22).
Metasoma: Tergite I 1.8× as long as wide.
Color (as in Figs 42–43): Head and mesosoma basically black except for the following: Mouthparts except mandibular teeth, labrum, clypeus, gena, inner part of eye notch, posterior margin of pronotum, tegula. Forecoxa brown and yellowish, trochanter, femur and tibia yellowish with brown markings on femur, foretarsus brown. Mid- and hindleg brown with basal section of tibia and ventral surface of tarsomeres II–V yellowish. Dorsolateral side of antennae brown, ventrolateral side pale brown. Metasoma dark brown except the following: anterior section of tergites II–III pale yellowish.
Pilosity: Body, including legs, largely covered with dense setae. Setae distinctly shorter on head, mesoscutum and scutellum, and lacking on following structures: occiput, ventrolateral side of pronotum, median area of mesepisternum, ventral part of metepimeron, anteroventral of metepisternum, median part of lateral side of propodeum and posteroventral half of hindfemur.
Life history. Nothing is known.
Etymological note. The specific epithet refers to ‘ Guanabara ’, the oceanic bay with Rio de Janeiro on its western shore, where the holotype was collected; it is a noun in apposition.
Note. This specimen was part of the original type series of L. varius Townes, 1977.
