Dolichoderus gordoni

sp. n.

Dolichoderus gordoni  sp. n.

( Fig. 12View FIGURE 12)

Types. Holotype worker from Fletcher, 28 ° 46 'S 151 ° 51 'E, Queensland, E. Sutton (ANIC, ANIC 32 -066637); 18 paratype workers, same data as holotype except ANIC 32 - 061389 (15 in ANIC, 3 in MCZC).

Diagnosis. Pronotum and propodeum with elongate spines; the short pronotal spines are directed anteriorly and approximately parallel to the longitudinal axis of the body, in dorsal view a line drawn between their tips intersects the pronotal collar; the first gastral tergite generally lacking hairs, but with a few scattered, very small appressed hairs.

This species is most similar to D. etus  and D. doriae  . They differ in that D. gordoni  lacks fine pubescence on the first gastral tergite but has a few scattered, very small appressed hairs. In addition, the overall colour of the body is a lighter red-brown, rather than a dark brown-black. Additionally, variation in pronotal spine length is displayed between D. gordoni  and D. etus  . Dolichoderus gordoni  appears to have shorter, straighter pronotal spines, whereas D. etus  has long spines with a distinct curve near the base of the spine. Spine length between D. gordoni  and D. doriae  appear similar.

Worker description. See Fig. 12View FIGURE 12. All available material is similar to the figured individual.

Measurements (n= 5). CI 99–100; EI 17–19; EL 0.27–0.31; HL 1.60–1.66; HW 1.59–1.64; ML 2.46–2.61; MTL – 1.75 – 1.71; PronI 67.30–71.06; PronW 1.07–1.15; SI 103–108; SL 1.64–1.77.
