Calyptomyrmex loweryi Shattuck, 2011 View in CoL

Material examined. Bukit Batok East, 29 Sep 2016, G.W. Yong leg., ZRC _HYM_0000991 .

Material not physically examined. Unknown.

Literature. None. New record.

Localities. Bukit Batok East

Habitat/Ecology. A single specimen was found in mature or young secondary forest in Singapore. This species has only been found in one locality to date.

Remarks. Calyptomyrmex loweryi is very similar to the more widespread C. beccarii , but can be distinguished from the latter by its relatively larger size, wider head (HW generally> 1.13 mm, see Shattuck 2011; 1.15 mm in the Singapore specimen) and broader posterior margin of head. However, we noticed

some larger specimens of C. beccarii with maximum head width slightly more than 1.10 mm, unlike what was diagnosed in Shattuck (2011). These larger workers were from the same colony as their smaller nestmates, whose measurements better fulfilled the diagnosis for C. beccarii . Thus, size should be used with caution when differentiating between C. loweryi and beccarii .
