Key to Turneria species

AntWiki: The Ants --- Online

The following key to Turneria species has been modified from Shattuck (1990[1], 2011[2]).

1

  • Propodeum low and lacking rounded protuberances; abundant long erect hairs present on the dorsal surfaces of the head and mesosoma => Turneria rosschinga
  • Propodeum high and with rounded protuberances; erect hairs on the dorsal surfaces of the head and mesosoma limited or absent => 2

2

  • One or two erect hairs present on frontal lobes => 3
  • Erect hairs absent from frontal lobes => 5

3

  • Body uniformly colored: yellowish brown to reddish brown (eastern islands of Papua New Guinea, Solomon Islands, Vanuatu) => Turneria dahlii
  • Body strongly bicolored with head and gaster of contrasting color: head yellow, gaster reddish brown => 4

4

  • Propodeum in dorsal view with the lateral protuberances extending posteriorly (giving a concave appearance) so that a line drawn between them would not contact the medial areas; eyes placed relatively high on head (fig. 15) (ROOD < 0.26); head and mesonotum short (HL < 0.70, ML < 0.27) (Papua New Guinea) => Turneria postomma
  • Propodeum in dorsal view without lateral protuberances extending posteriorly and with the posterior margin even or convex across entire width; eyes placed relatively low on head (fig. 19) (ROOD > 0.29); head and mesonotum long (HL > 0.71, ML > 0.29) (Solomon Islands, Vanuatu) => Turneria pacifica

5

  • Lateral areas of head with weak imbricate sculpturing and with the integument shiny; eye spread large (ES > 0.35) (Papua New Guinea) => Turneria collina
  • Lateral areas of head with moderate imbricate sculpturing and with the integument opaque; eye spread small (ES < 0.35) => 6

6

  • Propodeum in dorsal view with the lateral protuberances extending posteriorly (giving a concave appearance) so that a line drawn between them would not contact the medial areas (Australia) => Turneria bidentata
  • Propodeum in dorsal view without lateral protuberances extending posteriorly and with the posterior margin even or convex across entire width (Papua New Guinea) => Turneria arbusta
