Figs. 3 , 6 , 7 , 8 , 9, 10, 11, 13 and 14.

Neoneura bilinearis: Calvert 1909: 212 (male listed, see remark below); Williamson 1917: 213 (male key), 215 (female key), 219 (description), plate XIV (male appendages), plate XVII (hind lobes of pronotum Fig. 77 male, Fig. 78 female), plate XVIII (Fig. 100, male wings); Kennedy 1917: 294, Figs. 43–44 (genital ligula illustrated); Garrison 1999: 346 (male key), 349 (female key), 352 (male illustrations appendages), 353 (notes), 366 (female illustration); Lencioni 2005: 197 (notes and reproduction illustrations from Williamson 1917 & Garrison 1999; Figs. 125 F–H: illustrations thoracic color pattern and head color pattern, male original drawings); Heckman 2008: 590 (key and reproduction of Williamson 1917 illustrations); Garrison, von Ellenrieder & Louton 2010: 369 (list) and 371–372 (figure reproduction of Garrison 1999).

Remarks. The record in Calvert (1909) (Espiritu [sic] Santo State, 1 3 Muniz Freire (20°27′50″S 41°24′46″W), 18 ix1908, leg. J.D. Haseman (CMP)) might be a first misidentification of N. bilinearis Selys , as the collection location in eastern Brazil is 2000 km south of the now known distribution area of N. bilinearis Selys ( Fig. 5 ). Curator J. E. Rawlins could not find this specimen in an initial look in the vast CMP collection of Odonata (mail 27 June 2011). Williamson (1917) based his erroneous redescription of N. bilinearis Selys on several individuals from Wismar ( Guyana) and on 1 3 from Poco Grand, Brazil, 28 xii 1897 (CUIC) (likely São Paulo State, Poço Grande Stream, Juquiá (24°19'17.16"S 47°38'14.43"W )). According to the male appendages both must be regarded as N. confundens .

Etymology. From confundens (Lat.) meaning confusing: this species has been confused for nearly 100 years with N. bilinearis . Its color forms and variability make it also a confusing species.
