Fleck, Günther & Neiss, Ulisses G., 2019, The larva of the genus Misagria Kirby, 1889 (Odonata: Libellulidae), Zootaxa 4706 (3), pp. 461-468 : 465

Preliminary larval diagnosis of the genus Misagria

The diagnosis is based on Misagria parana described in this paper, on F-0 Misagria divergens De Marmels, 1981 , from Roraima State, Brazil (Neiss, in litt.; Neiss and Fleck, pers. obs.), and on F-0 Misagria cf. calverti from Amazonas State, Brazil (Fleck, pers. obs.). It may change after the discovery of new larvae belonging to the genus (ie M. bimacula Kimmins, 1943 ) or to closely related genera: (1) rather small (<20mm) and pilose larvae, covered by long and hair-like setae; (2) functional parts of eyes small and moderately projecting above dorsal part of epicranium; (3) occiput well developed, with short parallel lateral margins behind eyes; (4) incisors 1 and 2 almost completely fused on right mandible, with two and three molar teeth respectively on left and right mandible; (5) mask broad with prementum about as long as wide, and short, its posterior margin just reaching the anterior part of mesocoxae; (6) disposition of premental setae “S” shaped, and separated into three groups: (7) three long external setae well separated from each other by at least two times the diameter of setal basal insertion, one setae of medium size, and, close to the seta of medium size, several [6−10] shorter setae “U” or “V” disposed; (8) seven palpal setae, the distal one distinctly shorter than others; (9) crenulations on distal margin of palp smooth and squarish, numbering nine (rarely eight), each tooth with a small ventral indentation, and median teeth bearing generally three or four raptorial setae; (11) costal margins of wing pads parallel; (12) metatarsus and claws rather long and thin, with length of tarsus+claws slightly shorter than metatibia (ca 0.80 to 0.85 the length of tibia); (13) pro- and metatarsi with one row of trifid setae; (14) abdomen elongated, without dorsal hooks and with moderately developed lateral spines on S8 and S9 (length <middorsal length of their respective segment); (15) S3−S9 with middorsal rather diffuse but distinct clump of setae; (16) anal pyramid elongated with all elements acutely pointed, and with epiproct about 1.5 to 2 times as long as broad, paraprocts about as long as epiproct, and male cerci ca 0.4–0.6 of the epiproct (female cerci shorter). None of these characters is unique to the genus Misagria .
