Hypoponera opaciceps (Mayr


Hypoponera opaciceps (Mayr  HNS  1887).

Ponera opaciceps Mayr  HNS  1887: 536. [lectotype w examined, NHMW; Santa Catharina, Brazil] 

Hypoponera opaciceps (Mayr)  HNS  . Taylor 1967: 11.

Ponera opaciceps var. postangustata Forel  HNS  1908b: 343. NEW SYNONYMY. [holotype w examined, MHNG; San Bernadino , Cordillera, Paraguay (Fiebrig)]  .

Hypoponera opaciceps postangustata (Forel)  HNS  . Kempf 1972: 123.

Forel (1908h) distinguished the variety postangustata  HNS  from H. opaciceps  HNS  on the basis of having a more convex head shape, but having examined and photographed both Mayr’s and Ford's types, I can find no discernable difference in shape. Both ants are remarkably similar in most respects except for color- the H. opaciceps  HNS  type is piceous while H. postangustata  HNS  is ferruginous. In any case, H. opaciceps  HNS  is variable in many characters even within nest series. Ford's H. postangustata  HNS  type falls well within the bounds of variation of H. opaciceps  HNS  and I synonomize it here.
