Polyrhachis Queenslandica
''Polyrhachis'' is a genus of formicine ants found in the Old World with over 600 species. The genus is yet to be comprehensively resolved and contains many varied species including nest-weavers (e.g. ''Polyrhachis dives''), swimming workers (e.g. ''Polyrhachis sokolova''), soil (e.g. ''Polyrhachis proxima'') and tree-dwellers (e.g. ''Polyrhachis bicolor''). General morphology Size: Workers range in size approx 5-10mm in length. Eyes developed, no ocelli. Antennae have 12-segments. Antennal insertions situated far from posterior margin of clypeus. Mesosoma of most species have spines on one or more of its pronotal, mesonotal or propodeal components. Petiole armed with spines or teeth. First gastral tergite well developed, longer in dorsal view than exposed parts of the following terga together. Opening at gastral apex for release of venom lacking a radial fringe of hairs. Ecology ''Polyrhachis'' species include an array of nesting types ranging from terrestrial, soil based n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyrhachis Gracilior
''Polyrhachis gracilior'' is a species of ant found in the southwest and northeast India. It is one of the few ants that build arboreal nests made of leaves stitched together using silk produced by their larvae. Originally described as a "race" of ''Polyrhachis furcata'', it was elevated to a full species by Charles Thomas Bingham, C T Bingham who noted differences in the shape of the spines. A species described from Travancore as ''weberi'' by Horace Donisthorpe in 1943, was identified as being identical to ''gracilior'' by Barry Bolton.
