Remarks. Mesamphiagrion laterale seems to be the most abundant species of the genus in the Cordillera Oriental; “wetland populations are so numerous that grass seems to flower in blue” (Realpe pers. comm.). There are two records of this species from the Cordillera Central, which are doubtful as explained below.
Navás (1934) described Argia ternaria based on material collected by Brother Apollinar María, who lived in Bogotá, from the municipalities of Pensilvania, Caldas department, in the Cordillera Central, Quetama [sic.] (probably Quetame), and Coachí, Cundinamarca department, in the Cordillera Oriental. This name was synonymized under M. laterale by Donnelly & Alayo (1966) based on the specimen collected in Quetame. This species has not been recorded again from Caldas Department, and during a recent trip to Pensilvania CAB searched unsuccessfully for specimens of the genus Mesamphiagrion.
The type series deposited in the British Museum of Natural History (1♂ lectotype) and Brussels Museum of Natural Sciences (2♂ paralectotypes) are labeled Cauca Dept.: Nueva Granada, M. Mac Lachlan leg. Cauca department changed its jurisdiction over time; it once covered all the land between northern Chocó and the Amazon lowlands, including the three cordilleras: Occidental, Central, and Oriental (Acosta 1856). Current political boundaries of Cauca only cover the Occidental and Central cordilleras. von Ellenrieder & Garrison (2008), and Pérez-Gutiérrez & Palacino-Rodríguez (2011) following them, recorded M. laterale from the current Cauca department at the Central Cordillera; however there are no further records to support this distribution, and a recent expedition to the department made by CAB was negative.
The color pattern of mature males (Figs. 11 a, 12 l) is quite similar to that of M. gaudiimontanum and M. nataliae. Juveniles have red coloration on S1–3 (Fig. 11 b–d). Females show plasticity in the color of S8, with two light blue spots present or absent (Fig. 13 o–q). Also, plasticity has been observed in some diagnostic traits, with ventrobasal process of male cercus elongated and with sharp apex pointing proximally or quite undeveloped, and the posterior lobe of pronotum presenting subtle variations in its concavity.
Habitat and biology. Males and females were observed near lentic water bodies such as reservoirs, small lakes, and marshes. Apparently this species prefers places with riparian vegetation such as grasses and shrubs, which it uses as shelter from the wind.
Distribution. This species encompasses the widest altitudinal range observed for the genus, from 750 to 2,850 m.a.s.l., extending from the Cordillera de Mérida in Venezuela to the Llanos foothills in the Cordillera Oriental (Fig. 15).
