Rogeria stigmatica

Identification
Kugler (1994) - WL 0.72-0.92mm. Mandibles usually subtriangular. EL usually ≥ 0.10mm. Propodeal spiracle ≤ half its diameter from edge of infradental lamella. Propodeal spines short (PSI 0.07-0.13), strongly inclined dorsad. Metapleural lobes much reduced. Inferior petiolar process absent. Abundant decumbent hair on head, mesosoma, waist and gaster; erect hairs rather sparse, not flexuous.

Distribution
This taxon was described from New Guinea. It is also found in New Caledonia.

Worker
Kugler (1994) - TL 3.0-3.7, HL 0.66-0.83, HW 0.58-0.71, SL 0.46-0.61, EL 0.05-0.15 (7-34 facets), PW 0.44-0.52, WL 0.72-0.92, SpL 0.05-0.10, PetL 0.32-0.42, PpetL 0.19-.23mm, CI 0.84-0.92, OI 0.08- 0.22, SI 0.79-0.87, PSI 0.07-0.13. N=28

Mandibles subtriangular (usually) to triangular; with 5 subequal teeth or 3 apical teeth followed by 3-4 (rarely 5) smaller teeth or denticles. Palpal formula 3,3. Little or no clypeal apron; median clypeal margin truncate, weakly convex, or weakly angular. Body of clypeus not projecting over clypeal margin. Eyes oval, large (EL 0.10-0.15mm and 17- 34 facets), except in some of the Papua New Guinea workers (EL 0.05-0.07mm; 7-9 indistinct facets). Nuchal groove distinct from behind, but not clear in side view. Promesonotum with evenly convex profile. Metanotal suture narrow, emphasized by a sharp ridge at anterior edge of propodeum. Node large, wider than long, more or less symmetrical in side view (Fig. 8). Postpetiolar node in side view rounded front to back; usually widest in anterior half, much as in Fig. 66, but sometimes widest midlength. Postpetiolar sternum short. Sting apparatus like that of ciliosa (Fig. 3), except for: 1) spiniform medial and and lateral projections from anterodorsal corner of quadrate plates, 2) smaller valve chamber, and 3) lack of anterolateral processes on sting base (Fig. 9). Gonostylus sometimes with no clear sensillar gap; sometimes lacking a companion seta. The "Rogeria (stigmatica group) spp. 1 and 2" in Kugler (1978b) are both stigmatica. The sting shown here is more accurate than the previous one, which was not in full lateral orientation when drawn.

Middorsum of head longitudinally rugose; rest of head, including venter, coarsely areolate. Dorsum of promesonotum coarsely areolate to rugose (intermediate specimens predominantly areolate, but with elongate cells or short rugae medially; rarely, rugae also occur on shoulders). Anterior and sides of mesosoma areolate, finely so on neck and ventrad on meso- and metapleura. Spaces in sculpture smooth except for piligerous punctures. Dorsal face of propodeum areolate along very anterior margin, followed by either transversely rugulose or densely punctate sculpture, or both in varying degrees of density and definition. Petiolar peduncle finely colliculate or smooth. Anterior and apex of node smooth or areolate; posterior face and sides areolate, sometimes with a few rugae. Postpetiole transversely rugose-areolate behind, becoming more effaced anteriorly, often leaving anterior face smooth and shining.

Decumbent to subdecumbent pilosity covers most of body. Sparser erect to suberect hair also on dorsa of scapes, head, mesosoma, nodes, and gaster. Erect hair moderately abundant on gaster T1 of most specimens (Fig. 8), but sparse on specimens from Papua New Guinea. Body of clypeus with strong median seta.

Color of mandibles, frontoclypeal region, antennae, and legs light brownish-yellow to brown. Rest of body light brown to blackish-brown.

Queen
Kugler (1994) - TL 3.6-4.5, HL 0.73-0.85, HW 0.66-0.75, SL 0.53-0.62, EL 0. 19-0.24, PW 0.60-0.71, WL 1.00-1 .17, SpL 0.10, PetL 0.41-0.48, PpetL 0.21-0.26mm, CI 0.87-0.90, SI 0.80-0.84, PSI 0.09-0.10. N=6

As in worker except for the usual caste differences. Mesosoma habitus as in Fig. 10. Queen from McAdam Park, Papua New Guinea with median bulge on pronotum. Pronotum areolate on sides; finer and transversely rugose-areolate mesad. Mesoscutum longitudinally rugose; mesoscutellum areolate-rugose. Metanotum smooth. Mesosoma sides confused areolate, except for smooth area on mesokatepisterna and costulate metapleural gland bullae. Wing venation as in lirata (Fig. 30), except for Rs vein as in belti (Fig. 37).
