Description (gyne) Camelomecia sp.: Tong-112

: fully winged (Figs. S3A-E; S 4I)

Specimen preserved within large (2.5 x 2.8 x 1.1cm) piece of light yellow amber.

Description: Total length of ant approximately 6.3; some desiccation apparent in mouthparts, petiole, and gaster. Head shape very similar to C. janovitzi , 1.38 in length; eyes elongate, 0.58 long; ocelli large, bulging. Mandibles more elongate than C. janovitzi specimen, with overall cup-like shape with internal margin of sharp setae. Labrum partially cleared with few setae near posterior margin; lateral margins darkened, possessing sparse setae. Clypeus distinct from C. janovitzi , dorsally flattened with distinct posterior margin spanning width of head. Antennal segments flattened and distorted, preventing reliable measurement; scape approximately 0.75x length of flagellomere I. Pronotum with faint row of short setae along anterior margin, anteriorly pronotum narrowing greatly into neck before meeting head; promesonotal suture highly visible, appearing flexible, mesosoma constricted ventrally at this suture; scutellum bulbous, developed dorsally; propodeum with sheer posterior face, broadly rounded at posterodorsal margin, possessing stout spines; metapleural gland opening present, gaping. Propleuron reduced; mesopleuron developed, rounded laterally. Mid- and hind-legs with visible trochantellus; pretarsal claw with subapical tooth; tibial spurs as in C. janovitzi . Petiole pedunculae and elongate, gradually expanded to meet abdominal segment III, with single ventral spicule near anterior margin. Gaster elongate, distinct constriction between III and IV abdominal segments; third valvulae and sting visible.
