Plant associations are from Hendrickson (1930), Wilson (1982), Denno et al. (1987), Wilson (2012: 167), Seljak (2004), Badmin & Witts (2009: 213),  Wilson and Wheeler (2010), Ouvrard & Soulier-Perkins (2012: 441).

Economic Importance:

Potentially useful as a biocontrol agent (viz. Prokelisia marginata) of Spartina anglica (English cordgrass), in Washington where this grass has been introduced (Wu et al. 1999) (see Daehler and Strong 1996).

Prokelisia marginata has been inadvertently introduced to England and has become adventive in several countries in Europe.

Used extensively as a ecological model over nearly 30 years by Denno and colleagues (see Eubanks et al. 2011), particularly as a model for tritrophic ecological interactions and regarding between habitat and life history parameters.

Recognition

Wilson (1982) most recently revised the genus and Heady and Wilson (1990) provide features of female gentaila.  See also Denno et al. (1987).

Prokelisia is frequently abundant where in the vicinity of its host plant, although individuals can be collected at lights some distance from their expected habitat.

Except for Prokelisia crocea, members of this genus are very slightly dorsoventrally flattened, pale colored, with dark infuscations along the carinae of the frons.

Prokelisia crocea is distinctive in being larger than most members of the genus and having orangish markings on the face and thorax.  Prokelisia salina tends to be western and is more likely than some of the other species to be found inland; it can be separated from its congeners be the parallel-sided frons and diverging parameres.  Prokelisia carolae is a local species that is infrequently encountered.  Prokelisia marginata and P. dolus are quite similar and are found in broadly sympatric ranges.  Prokelisia dolus tends to have a much broader frons near the frontoclypeal suture than does P. marginata, but this difference is not always satisfactory.  More definitive is to view the male pygofer from lateral view (see figs. 7 and 10 in Wilson 1982), in Prokelisia dolus the parameres are inflected caudally near the apex, whereas in P. marginata the apices are dorsally directed.

Key to the Species of Prokelisia (lightly edited from Wilson 1992).
1. Lateral margins of frons markedly convex and widest at or below basally, with brown longitudinal markings (Figs. 2, 3); anal tube of male lacking spine-like processes (Figs. 7, 10) (coastal in eastern U.S. and California) … 2
1′.- Lateral margins of frons subparallel, if slightly convex then widest above basal 113, markings variable (Figs. 4-6); anal tube of male bearing elongate spine-like processes (Figs. 13, 16, 19, 22) … 3

2. Frons usually 2X or more longer than wide (Fig. 2); styles caliper-shaped, outer margins broadly rounded (Fig. 9); aedeagus lacking teeth on dorsal and ventral margins (Fig. 8) … P. marginata
2′.- Frons usually less than 2X longer than wide (Fig. 3); styles with outer margins angulate in distal 1/3 (Fig. 12); aedeagus with teeth near dorsal margin and often on ventral margin (Fig. 11) … P. dolus

3. Frons usually with brown longitudinal markings (Fig. 4); styles with apices directed laterally (Figs. 15, 18) … P. salina
3′.- Frons orange to yellow laterally and pale medially (Fig. 5) or entirely pale (Fig. 6); styles with apices directed medially (Figs. 21, 24) . . . 4

4. Frons orange to yellow laterally and pale medially, median carina weakly to well developed (Fig. 5); anal tube of male with dorsally and ventrally directed spine-like processes (Fig. 19); shaft of aedeagus widest basally (Fig. 20) (widespread in eastern and midwestern U.S.)
P. crocea

4′.- Frons pale, median carina strongly developed (Fig. 6); anal tube of male lacking dorsally directed spine-like processes (Fig. 22); shaft of aedeagus widest apically (Fig. 23) (California) … P. carolae
