Rogeria lacertosa

Nothing is know about the biology of this species.

Identification
Kugler (1994) - WL 0.93-1.05mm. Clypeal apron with median notch. Metanotal groove weak to strong. Petiolar keel with single lamellate carina. Sting shaft apex has dorsal flange; lancets acute; both weak. Macrosculpture not effaced on side of head below eye. Promesonotal rugae sharp and narrow like those on head. Sides of both nodes distinctly macroareolate. Erect hairs on scapes. No decumbent hair on gaster; little if any on mesosoma dorsum.

Similar to Rogeria germaini but differs in size (lacertosa larger), clypeal shape, sculpture on side of head, and pilosity. Rogeria pellecta, also from southern Brazil, differs in petiole keel, sting and lancets, promesonotal sculpture, and pilosity.

Distribution
Only from the type material collected from 100-200m elevation in southern Brazil.

This taxon was described from Brazil.

Nomenclature

 *  lacertosa. Rogeria lacertosa Kempf, 1963a: 194, fig. 5, 6 (w.) BRAZIL. See also: Kugler, C. 1994: 44.

Worker
Kugler (1994) - TL 3.6-4.0, HL 0.83-0.91, HW 0.72-0.81, SL 0.59-0.61, EL 0.10-0.11 (19-20 facets), PW 0.52-0.60, WL 0.93-1 .05, SpL 0.17-0.20, PetL 0.43-0.45, PpetL 0.23-0.26mm, CI 0.87-0.88, OI 0.13-0.14, SI 0.75-0.79, PSI 0. 18-0.20. N=4

The following supplements Kempf (1963). All specimens at hand with 6 mandibular teeth decreasing in size basad, except for a large basal tooth. Eyes elliptical. Nuchal groove forms a notch in lateral view of head. Anterior edge of propodeum not marked by a transverse carina. Metapleural lobes low and broadly rounded or triangular with more narrowly rounded apex. Postpetiolar node from above like that of pellecta. Sting apparatus as inermis, but sting shaft and lancets are less sclerotized (easily twisted) and the lancets lack the barbule.

Laterodorsa of head predominantly rugose to rugose-areolate. Back of head areolate in a transversely arched pattern. Microsculpture vestigial; intervals with a shiny, effaced granular appearance. Anterior face of pronotum transversely areolate; disc with diverging, longitudinal, vermiculate rugae with variable number of cross-ridges imparting a rugose-areolate appearance in places. Sides of mesosoma predominantly longitudinally rugose, but with occasional cross-ridges making elongate cells. Intervals in mesosoma macrosculpture shiny, nearly smooth, especially on sides. Anterior and sometimes dorsal faces of nodes weakly sculptured. Nodes slightly dulled by vestigial microsculpture.

Head dorsum with erect-suberect hairs in addition to the typical decumbent pilosity.

Color yellowish-brown; gaster slightly darker. Legs and, sometimes, antennae lighter, more yellowish. Mandibles often slightly darker than head capsule.

Type Material
