Aphaenogaster campana

Nothing is known about the biology of .

Identification
A member of the A. testaceopilosa group. Boer (2013) - The workers, gynes, and especially the males are rather easy to distinguish from the other species (see keys), and only because of their shiny parts they could be misidentified as Aphaenogaster semipolita (see worker key).


 * Key to European Aphaenogaster workers

Distribution based on Regional Taxon Lists
Palaearctic Region: Albania, Italy, Malta.

Nomenclature

 *  campana. Aphaenogaster testaceopilosa var. campana Emery, 1878b: 54, fig. (w.q.m.) ITALY. Subspecies of testaceopilosa: Emery, 1908c: 322; Emery, 1916b: 131; Emery, 1921f: 62. Raised to species: Dalla Torre, 1893: 100; Santschi, 1933c: 400; Baroni Urbani, 1971c: 40.

Worker
Boer (2013) - Lateral sides of mesosoma with distinct longitudinal rugulae. Rugulose sculpture on the dorsal side coarse. Most of the workers with longitudinal rugae on posterior part of propodeum. Head in full-face view with longitudinal rugulae with cross-connections. Clypeus of nearly all workers with transverse, U-shaped rugulae. Terminal side of propodeum, beneath the propodeal spines nearly smooth, sometimes transversely costulate. Dorsal half of lateral sides of petiole and postpetiole with or without punctation. Dorsal side of petiolar nodes punctate. Dorsal side of postpetiole with longitudinal costulae that continue into microstriae on first gastral tergite. Posterior half of gaster often smooth. Pronotum nearly glossy. Dorsal side of the gaster glossy satin. Head and mesosoma nearly matt. Dorsal half of lateral sides of petiole and postpetiole wax glossy. Dorsal side of petiolar nodes, terminal side of propodeum, beneath the propodeal spines and lateral sides of gaster glossy to shiny. Petiole equal in height to postpetiole or somewhat higher. Antennal club 4-segmented. Propodeum in lateral view generally slightly bulging. Setosity on propodeum longer than on other parts.

Measurements (n = 29). CI 69–80 (76); CL 1.16–1.57 (1.36) mm; CW 0.84–1.24 (1.03) mm; PHI 27–36 (32); PI 67–96 (81); PPPI 48–58 (51); PSI 144–200 (168); PSLWI 89–136 (114); PWI 20–35 (23); RPH 113–150 (133); RPSI 33–64 (46); SI 136–151 (144); SI/CI 173–230 (191); SL 1.32–1.70 (1.48) mm; SPD 1–3 (2.2); SPL 1–5 (1.7)

Queen
Boer (2013) - Longitudinal rugulae on head, scutellum, anterior side of postpetiole and on some parts of mesoscutum. Transverse rugulae on clypeus, pronotum, propodeum, posterior side of petioles and on some parts of mesoscutum. Punctation distinct on head, weakly pronounced on mesosoma and petioles. Less than ten transverse microstriae near base of first gastral tergite. Anterior side of the petiole smooth. Mesosoma dorsally matt glossy, gaster dorsally satin. Mesosoma and dorsal side of petioles glossy. Antennal club 4-segmented. Scape weakly or not at all rugulose. Scutellum rises slightly above the mesoscutum and bends over the metanotum.

Measurements (n = 3). CI 86–91; CL 1.70–1.77 mm; CW: 1.52–1.55 mm; OCI: 27–30 (28); PHI 129–132; PI 70–79; PPPI 63–69; PSI 213–233; PSLWI: 100–118; PWI 28–33; RPH: 36–37; RPSI 63–93; SI 106–110; SI/CI 116–124; SL 1.64–1.68 mm; SPL 1–4.

Male
Boer (2013) - Rugulae only on lateral parts of the propodeum. Punctation on head, lateral sides of the mesosoma, petioles and on clypeus very weak. Dorsal side of propodeum, petioles and dorsal side of gaster very weakly microreticulated, nearly smooth. Head, clypeus and mesoscutum softly glossy, dorsal side of gaster wax glossy. Dorsal side of propodeum, lateral sides of mesosoma and gaster shiny. Antennal club 5-segmented. Pubescence on hind tibia suberect to erect, their length longer than the diameter of the tibia. Mesoscutum strongly elevated (more than in other species). (Scutellum lower than mesoscutum, bent over metanotum. Head without frontal midline. No groove at posterior side of the propodeum, terminal end rounded. Propodeum wider than metasternum and bulging, saddle-shaped.

Measurements (n = 6). CI 94–102 (97); CL 0.70–0.78 (0.74) mm; CW 0.67–0.75 (0.72) mm; EYI 41–47 (43); OCI 40–45 (42); SL/CL 40–43 (41); SL 0.30–0.31 (0.31) mm.
