Acarapion nigrosuturatum (Béguin-Billecocq) , new combination

Apion nigrosuturatum Béguin-Billecocq, 1909: 459 . Type locality: Tucumán Province, Argentina. Syntype [? ?], labeled ‘‘ Type , République Argentine, Province de Tucuman, 15 July 1900, C. Bruch’ ’, examined (MNHN).

My determination of this species is based on three photographs of the syntype (probably male) which clearly show deep, coarse, close pronotal punctures; no other Argentinian specimens of this species were available. A provisional determination of A. nigrosuturatum is made for five / from the Atacama Region of Chile which show the same pattern of pronotal punctures. Based on this limited material A. nigrosuturatum has deep pronotal punctures frequently greater then 30 microns in diameter, the / rostrum seldom is longer than 0.40 mm, the distribution range is near 27 8 S latitude and the host plant may be Prosopis spp. ; for Acarapion ferruginosum the shallow pronotal punctures are seldom greater than 30 microns in diameter, the / rostrum usually is 84 THE COLEOPTERISTS BULLETIN 59(1), 2005

longer than 0.45 mm, the range is near 33 8 S latitude and the host plant may be

‘‘ Podanthus mitiqi ’’ or Acacia caven (Molina) Molina.
