Welcome to the new AntWeb!

We here at AntWeb have been busy working on our newest (and most ambitious) version of the site - and there are lots of great new things! Which means there are lots of changes (don't worry, they're all for the best).

And we've put together a handy little guide to show you all the new features and enhancements - why don't you have a quick look to check out all the new features and enhancements?

Taxonomic Treatment (provided by Plazi)

Shattuck, S. O., 2008:
(Figs 6-7, 14-16, 22)
Prionopelta opaca Emery , 1897: 596 (larva described by Wheeler and Wheeler, 1964: 447).
Prionopelta mocsaryi Forel , 1907: 1 (junior synonym of P. opaca by Brown, in Wilson, 1958: 149).
Types. Prionopelta opaca Emery : Worker, queen and male syntypes from Papua New Guinea ( MHNG , MSNG , examined). Prionopelta mocsaryi Forel : Worker syntypes reported from Paraguay but probably in error for a SE Asian locality (see Brown, in Wilson, 1958: 149 for details) ( MHNG , not examined).
Diagnosis. Anterolateral corners of head, near mandibular insertions, rounded. Dorsal mesosomal sculpturing composed of foveae which are only slightly more dense on the pronotum than on the mesonotum and propodeum, and which are uniformly distributed across the width of the propodeum. Body small, head width less than 0.48mm but petiole relatively broad, PetW greater than 0.21mm.
Description. Anterolateral corners of head, near mandibular insertions, rounded and lacking a tooth. Dorsal pronotal sculpturing consisting of foveae which are only slightly more dense than on the mesonotum and propodeum. Foveae on dorsum of propodeum uniformly distributed across its width. Lateral mesosomal sculpturing consisting of small foveae on pronotum and anterior region of mesopleuron, ventral regions of mesopleuron and propodeum weakly striate, posterodorsal region of mesopleuron and majority of propodeum smooth. Fenestra present but weakly developed within subpetiolar process. Colour yellow-red to red-brown.
Measurements. (n=12) CI 76-80; HL 0.47-0.52; HW 0.37-0.41; ML 0.54-0.62; PetL 0.16-0.20; PetW 0.21-0.24; PI 110-136; SI 65-70; SL 0.24-0.27; T 1W 0.31-0.36.

Comments. This species has so far only been found in rainforests with workers being collected from leaf litter on the forest floor. Nests occur in soil under objects and in rotten wood. P. opaca and robynmae have been collected from the same litter sample in PNG.

Wild, A. L., 2007:
Literature record: Central (Forel 1907b).
Forel described Prionopelta mocsaryi from “ Asunción , Paraguay.” Brown (in Wilson 1958) concluded that this was a misplaced locality and synonymized P. mocsaryi with the asian species P. opaca , with which it is nearly identical.
