In the first experiment, males were closely matched for body size (pronotum
length), and in the second, they were matched for body mass.
Mesosoma pale orange with all metapleuron, lower corner of mesopleuron, lower edge of pronotum
and propleuron, upper hind corner of pronotum
and tegula ivory.
Fortunately for the gardener, only a few of these larger, more conspicuous, species are likely to be seen in our gardens, and these can usually be identified by the colour and pattern of spots or other marks on the wing covers, the pattern on the pronotum
(the flattened plate in front of the wing covers), and by their general shape and size (Fig.
The first four components explained 84% of the total variation in the pronotum
finely pitted, projected on each anterolateral side.
rectangular, same width as elytra, with few punctuations laterally, mostly associated with the lateral fossae.

Diagnosis: Recognized within Physoderinae by the combination of the following characters: body small, about 4.5-5.0 mm; apterous; body covered by wide, stiff, curved hairs arising from prominent, wart-like tubercles (Figs 5, 6), markedly affecting outlines of head and pronotum
(Figs 7-10); ocelli absent; antennal segment I not reaching apex of clypeus (Fig.
