10. Heteroponera pendergrasti sp. n.

( Figs 50–53).

Type locality. AUSTRALIA: QUEENSLAND: NE Lamb Range (11 km SE Mareeba), -17 0 6, 145 34. Type deposition. Holotype ANIC. Paratypes in ANIC, QMBA.

Distribution, material examined. EA7 (Lamb Range): Mt Tiptree, -17 0 3, 145 37, (B. Halliday, 13.vi.1984), worker—900 m (RWT & JDF, 29.vi.1971), worker paratype -17 0 3, 145 38, 730 m (RWT & JDF, 29.vi.1971), worker paratype. Mt Edith, Lamb Range, -17 0 6, 145 37, QMBA berlesate 465, 1140 m (GBM, DKY & GIT, 11.x.1982) holotype, worker paratype. NE Lamb Range (11 km SE of Mareeba), -17 0 6, 145 34, QMBA berlesates 804, 822, rainforest moss, 1200 m 11.xi.1988 (GBM, GIT), holotype, 4 worker paratypes. Upper Isley Creek, -17 0 3, 145 41, trees & logs, pyrethrum, 750 m (GBM & Janetzki, 29.xi.1993).

Worker diagnosis. General features, conformation, color and major sculpturation as illustrated and in appropriate key couplets above. Characterized in the H. ecarinata species complex by heavy sculpturation, dark blackish color, with dark brown legs and antennae, and distinguished from the similar H. ecarinata by differences in sculpturation (particularly of the frons and second gastral tergite), coloration and structure of the petiolar node. Fore-coxae and posterior surface of node superficially microsculptured; propodeal declivity shining, with weak, superficial dorsally-directed radial striae; its sides distinctly sculpturally bordered, the posterolateral edge in profile micro-serrate as a result of minutely extended cuticular points along the sculptural border. Sculpturation of second gastral tergite more distinctly longitudinally deployed than in H. ecarinata (refer Figs). Dimensions: (holotype; smallest available specimen, largest available specimen (both Mt): TL (ca): 5.1, 4.8, 5.1; HW: 1.23, 1.18, 1.23; HL: 1.19, 1.17, 1.18; CI: 103, 100, 104; EL: 0.16, 0.16, 1.18; SL: 0.71, 0.69, 0.70; SI: 57, 58, 57; PW: 0.86, 0.86, 0.90;WL: 1.54, 1.49, 1.58; petH: 0.85, 0.79, 0.90; petW: 0.46, 0.47, 0.47; GW 0.99, 0.96, 1.03.

Related taxa. See above under H. ecarinata .

In-group sympatric associations. Heteroponera relicta and H. pendergrasti are both present in QMBA Berlesate 804.

Biogeography. known only from Lamb Range, the northern rampart of the Atherton Tableland. H. pendergrasti is possibly endemic there. Note the frequency of accessions by various collectors, and the absence of records in the well-known, generally well collected and more frequently visited nearby EA9, Atherton Tableland and EA6 Black Mountain localities.

Remarks. The apically sub-dentate petiolar node is (probably homoplasiously and convergently) similar to those of some Neotropical species (Brown 1958; Feitosa 2011).

Etymology. Named for Professor J.G. (Jim) Pendergrast of Auckland, New Zealand, my first teacher in Zoology at both High School and (in a later position) at The University of Auckland, where he supervised my M.Sc. degree.
