Rogeria sicaria

Only known from the holotype.

Identification
Kugler (1994) - Most similar to but not quite like other species in the germaini species group. WL 0.75mm. Eye very small. Clypeal apron convex. Metanotal groove strong. Propodeal spines very long, strongly inclined dorsad and divergent. Petiole long (PetL/PW 0.95), with prominent keel. Sting apex strong, with dorsal flange. Sides of head below eye, mesosoma, and petiolar node areolate; coarsely so on mesosoma. No erect hair on scapes. Head, mesosoma dorsum, nodes, and gaster T1 with stiff, erect-suberect hairs and shorter, more abundant, appressed-decumbent hair.

It seems related to Rogeria germaini, Rogeria pellecta, and Rogeria lacertosa, also from southern Brazil.

Nomenclature

 *  sicaria. Rogeria sicaria Kempf, 1962b: 22, figs. 20, 21 (w.) BRAZIL. See also: Kugler, C. 1994: 45.

Worker
Kugler (1994) - Holotype. TL 2.8, HL 0.67, HW 0.56, SL 0.48, EL 0.03 (8 facets), PW 0.37, WL 0.75, SpL 0.22, PetL 0.35, PpetL 0.17mm, CI 0.83, OI 0.05, SI 0.86, PSI 0.29.

The following supplements Kempf (1962b). Mandible triangular, with 5 teeth decreasing in size to base. Clypeal apron evenly convex; body of clypeus projecting over mandibles. Frontal lobes narrow (FL W /HW 0.29). Eyes small, circular, somewhat sunken in head. Petiolar peduncle long (PetL /PW 0.95), with strong keel and dentate inferior process. Postpetiole highest in caudal half; dorsal view subtrapezoidal as in Fig. 49.

Posterior head areolate and more coarse than elsewhere on head. Intervals shiny, but dulled somewhat by vestigial microsculpture. Areolate sculpture on petiolar node not as well defined as on head and mesosoma and even more effaced on postpetiolar node. Nodes roughened by vague microsculpture.

Color uniformly golden-brown.
