Limnocoris hintoni La Rivers (Fig. 1) Limnocoris hintoni La Rivers, 1970: 3–4 (original description). Published records. México: Estado de México, Guerrero, Jalisco, Oaxaca, Puebla (La Rivers 1970, Nieser & López-Ruf 2001, Reynoso-Velasco & Sites 2019b, Rodrigues & Sites 2019). New state records. México: Michoacán, Morelos. Distribution. This species is distributed exclusively in Mexico, in the central-south part of the country (Fig. 1). The range of L. hintoni was considered to be predominantly along the Transmexican Volcanic Belt biogeographic province (Rodrigues & Sites 2019); however, a more detailed examination of all records, previously published and those herein presented, uncovered a different distribution pattern, in which the great majority of records are exclusively within the Balsas Basin biogeographic province. That includes four previously reported (Rodrigues & Sites 2019) records from Oaxaca and Puebla. Records from specimens in the type series (Estado de México, Puebla) are on the border of the Balsas Basin and Transmexican Volcanic Belt biogeographic provinces, but those can be considered to be in the Balsas Basin province since all of them are below 2000 meters, which is a characteristic of this biogeographic province. The westernmost records of the species are on the border between the Balsas Basin and Sierra Madre del Sur (Michoacán district) provinces. The sole record from Jalisco (Nieser & López-Ruf 2001) is on the confluence of three biogeographic provinces (Pacific Lowlands, Transmexican Volcanic Belt, Chihuahuan Desert) and approximately 200 kilometers north of the closest records in western Michoacán. The specimen (or specimens) on which this record was based was not examined during the recent revision of the species of Limnocoris from North America (Rodrigues & Sites 2019) and could represent a misidentification of a related species distributed in western Mexico. Based on this, L. hintoni can be considered a species endemic to the Balsas Basin province. Material examined. MÉXICO: ESTADO DE MÉXICO: Mpio. Amatepec, Río San Felipe, 05-May-2008, R. Novelo coll.
