description: <i>Paraphlepsius</i> spp. (Fig. 3 F–I) <b>Description.</b> Coloration brownish, color pattern consists of numerous dark brown specks; two longitudinal pale stripes in anterior part of body; abdomen with pale stripes near sides of tergites. Abdomen with pale longitudinally expanded setal areolae, lateral areolae with darkened margins; dark spots between median and lateral rows of setae near anterior margins of tergites. Head with two dark spots at apex. Face largely dark, with broad pale stripes along sutures. Legs with dark setal areolae. <b>Notes.</b> Nymphs of 3 unidentified species from Illinois (USA) were studied. Nymphs of <i>P. altus</i> (Osborn &amp; Ball) were illustrated by Osborn and Ball (1898f), <i>P. nebulosus</i> (Van Duzee) by Osborn and Ball (1898f) and Osborn (1928), and <i>P. irroratus</i> (Say) by Osborn (1928, 1932). The preliminary key to tribes of immature Nearctic Deltocephalinae includes both native and introduced groups. An interactive key to tribes and subfamilies of Cicadellidae is also available from the web site (see Dmitriev 2003 onward). <b>Preliminary key to Nearctic tribes of Deltocephalinae based on fifth instar nymphs</b> 1.
