LOPEZ RUF, Mónica; MORRONE, Juan J.  y  HERNANDEZ, Emilia Paulina. Distributional patterns of Argentinean species of Naucoridae (Hemiptera: Heteroptera). Rev. Soc. Entomol. Argent. [online]. 2006, vol.65, n.1-2, pp.111-121. ISSN 0373-5680.

Distributional patterns of Argentinean species of Naucoridae were analyzed. Based on a track analysis of 23 species, five generalized tracks were found: (1) northwestern-central Argentina (Jujuy, Salta, Tucumán, Catamarca, La Rioja, Córdoba, and San Luis provinces), determined by Ambrysus bergi Montandon , A. fucatus Berg , A. gemignanii De Carlo , A. ochraceus Montandon , Limnocoris borellii Montandon , L. pectoralis Montandon and L. ovatulus Montandon ; (2) northeastern-north Argentina-Mesopotamia (Jujuy, Salta, Formosa, Chaco, Santa Fe, Corrientes, and Entre Ríos provinces), determined by Ambrysus kolla López Ruf , Pelocoris binotulatus binotulatus (Stål) , P. binotulatus nigriculus Berg and P. bipunctulus (Herrich-Shäffer) ; (3) northeastern-north Argentina (Corrientes, Formosa, Chaco y Tucumán provinces) and Paraguay, determined by Ctenipocoris schadei (De Carlo) , Pelocoris politus Montandon , P. procurrens White , and Limnocoris minutus De Carlo ; (4) northeastern Argentina (Corrientes and Misiones provinces), determined by Ambrysus acutangulus Montandon , A. attenuatus Montandon , Cryphocricos barozzii Signoret and C. vianai De Carlo ; and (5) northeastern Argentina (Misiones y Corrientes provinces) and Brazil, determined by Ambrysus truncaticollis De Carlo , Limnocoris pusillus Montandon , Pelocoris magister Montandon , and P. subflavus Montandon. Three nodes were identified, one in northwestern Argentina (Yungas biogeographic province), in the intersection of generalized tracks 1 and 2 (A), and two in northeastern Argentina ( Chaco and Parana Forest biogeographic provinces), in the intersections of generalized tracks 2, 3, and 4 (B) and 4 and 5 (C).
