Revision of the ant genus Calyptomyrmex (Hymenoptera: Formicidae) in South-east Asia and Oceania Author Shattuck, Steven O. text Zootaxa 2011 2743 1 26 journal article 10.5281/zenodo.276598 db749b2d-e601-4558-beb0-4d7414b7350a 1175-5326 276598 Calyptomyrmex taylori sp. n. ( Figs 17 , 18 ) Types . Holotype worker and 1 worker paratype from 3.0km W Cape Tribulation (Site 6), Queensland, 20 September 1982 , rainforest, sieved litter, Monteith, Yeates & Thompson ( holotype ANIC32- 051625 , paraytype ANIC32- 053403). Paratypes : 2 workers , same data as holotype except 19 September 1982 (ANIC32- 051626 ( 1 in ANIC, 1 in MCZC)); 1 worker , same data as holotype except 2 October 1982 (ANIC32- 051627 ). Diagnosis. Hairs on head and body spatulate (noticeably narrower near the body and expanded distally and with a rounded tip), gaster indistinctly punctate, propodeum unarmed, in dorsal view node of petiole rectangular, body smaller (HW < 0.85mm ). Within Australia , taylori is most similar to beccarii but differs in having narrower spatulate hairs on the head, a more rectangular petiolar node (in dorsal view) and in being smaller (HW < 0.85mm rather than> 0.90mm ). FIGURE 17. Calyptomyrmex taylori (holotype, ANIC32-051625): A. Front of head; B. Side of body; C. Top of body; D. Distribution of material examined. Worker description. Mandibles striate. Eyes with 4–5 ommatidia in greatest diameter. Propodeum in lateral view lacking angles or spines. Propodeal lobes thin anteriorly, thickened posteriorly. Node of petiole in profile slightly higher and larger than that of postpetiole. In dorsal view the petiolar node much broader than long and slightly narrower than postpetiolar node. Head weakly rugose, the rugae enclosing foveolate spaces, the underlying surface indistinctly punctate. Promesonotum, sides of mesosoma and dorsum of petiole and postpetiole with illdefined longitudinal rugae which are slightly stronger laterally than dorsally. The underlying surface of the mesosoma, petiole, postpetiole and gaster indistinctly punctate. Hairs on head and body narrowly spatulate and raised above the surface of the body. Clypeal fork with enlarged, short and thin, elongate hairs. Colour dull red-brown, antennae and legs slightly lighter. Measurements. Worker (n = 10) - CFW 0.09–0.11; CI 92–97; HL 0.76–0.83; HW 0.72–0.80; ML 0.70–0.81; MTL 0.31–0.38; PetI 174–201; PetL 0.17–0.20; PetW 0.33–0.36; PronW 0.49–0.55; SI 58–64; SL 0.44–0.51. Additional material examined ( ANIC ). Australia : Queensland : 1.5km EbyN Mt. Sorrow (Calder,A. & Weir,T.), 1.5km W Cape Tribulation (Site3) (Monteith, Yeates & Thompson), 2.0km WNW Cape Tribulation (Site 2) (Monteith, Yeates & Thompson; Monteith,G.B.; Monteith,G.B. & Yeates,D.K.), 3.5km W Cape Tribulation (Site 7) (Monteith, Yeates & Thompson; Monteith,G.B.), Mt. Sorrow summit, Cape Tribulation (Monteith,G.B.), Noah Creek (Taylor & Feehan), nr. Cape Tribulation (Taylor,R.W. & Feehan,J.). Comments. Calyptomyrmex taylori is known from numerous collections made within a tiny area near Cape Tribulation, Cape York Peninsula, Queensland. All collections have been from rainforest leaf litter.
