Body not compressed (unlike Prokelisia). Head, including compound eyes, slightly larger than pronotum, vertex in dorsal view weakly projecting between eyes. Carinae of head strong and conspicuous, except median carina of vertex; median carina of frons forked on fastigium near dorsal margin of compound eye. Frons with lateral margins subparallel, narrowed between eyes. Lateral carinae of pronotum diverging, not reaching posterior margin; median carina reaching hind margin at shallow notch. Lateral carinae of mesonotum diverging, reaching posterior margin, median carina becoming obsolete in scutellum. Forewings of brachypter clear, subtruncate, leaving several tergites exposed. Apex of hind tibiae bearing 7 (3+4) spines, with 5 (2+3) on basitarsus and 4 on second tarsomere. Calcar with 18-31 teeth (x = 24.0, n=26).</p><p>Male terminalia with pygofer rather quadrate in lateral view, dorsocaudal margin of pygofer weakly projecting. Opening of pygofer broad, wider than long, with lateral margins of opening carinae, ventral margin smoothly rounded. Diaphragm strong and conspicuous, dorsal margin broadly U-shaped, bearing median, bilobed armature subtending the aedeagus, much wider than tall. Parameres exerted through broad opening in diaphragm; parameres strongly flattened, sides subparallel, strongly diverging, basal and apical angles weakly developed. Aedeagus widest in basal third, then abruptly narrowed with distal 2/3 strongly downcurved; suspensorium U-shaped, weakly apparent. Segment 10 broad, bearing strongly developed pair of weakly sinuate processes on caudal margins near lateral margins. Segment 11 about 2/3 height of segment 10.</p><p>Macropters darker than brachypters, with abdomen and lateral portion of mesonotum more strongly embrowned. Macropterous wings are clear (no dark marking at apex of clavus), exceeding length of abdomen nearly by length of abdomen.</p><p>Remarks.</p><p>Spartidelphax penedetectus was chosen as the type species since the holotype of Delphax luteivitta is in unsatisfactory condition and the lectotype of Liburnia detecta could not be located (although putatively at the USNM). The holotype of Delphacodes penedetecta Beamer, 1950, is at SEMC.</p><p>Spartidelphax is phylogenetically placed at the base of a strongly supported clade with the genera Prokelisia Osborn, Neomegamelanus McDermott, and Tumidagena McDermott based on the phylogenetic investigation of Delphacidae using DNA nucleotide sequence data from four genetic loci (18S rDNA, 28S rDNA, wingless and cytochrome oxidase I) and 132 coded morphological characters by Urban et al. (2010). These three genera and Spartidelphax are associated with Spartina Schreb. ( Poaceae, cordgrass), and are abundant in salt marshes in eastern North America. Prokelisia, Neomegamelanus, and Tumidagena are more slender forms with their body weakly to strongly compressed, and their vertex more strongly projecting. Members of Prokelisia are most similar, including having the carinae on their frons bordered by dark (except Prokelisia crocea), but they are more slender, usually with the frons broadest ventrally, parameres either distally converging or slender and diverging, and the aedeagus is usually upturned. Superficially more similar to Spartidelphax are species now placed in Muirodelphax Wagner, but North American species in this genus lack processes on segment 10. Also similar are Toya Distant, Metadelphax Wagner, and Syndelphax Fennah, but the dorsocaudal angles of the male pygofer of these genera are greatly expanded (Gonzon and Bartlett 2008).</p><p>In the "Key to genera of Delphacidae North of Mexico" of Bartlett et al. (2014), Spartidelphax keys to couplet 75, where Spartidelphax can be inserted in place of the entry for Delphacodes detecta and Delphacodes penedetecta .</p><p>Etymology.</p><p>The generic name is an arbitrary combination of letters formed by combining a truncation of Spartina (the host grass genus) with -delphax, a common termination used in delphacids. The name is to be treated as masculine ( Delphax was affirmed as masculine by ICZN 1961).</p><p>Key to species of Spartidelphax (males)</p></div>	https://treatment.plazi.org/id/446D8E3848A122CD02B0BFDB01B8DC98	Public Domain	No known copyright restrictions apply.

(smooth cordgrass) (Denno 1977, 1978), with Spartina alterniflora “… an inferior host plant for development" (Denno 1977: 366). Distichlis spicata (L.) Greene (saltgrass, Poaceae) was reported on specimen labels.</p><p>Distribution.</p><p>USA: CT, DE, FL, GA, LA, MA, MD, ME, MS, NC, NJ, NY, RI, SC, TX, VA, VT; CAN: NS, PE, QC; Anguilla, Bahamas (Exuma, Berry, Eleuthera); Bermuda, British Virgin Islands (Guana, St. Thomas), Jamaica, Mexico, Puerto Rico (inc. Vieques Is.), Turks &amp; Caicos (Bartlett et al. 2014).</p><p>Remarks.</p><p>Liburnia detecta Van Duzee, 1897, was described from 2 specimens (1 male, 1 female) from New York City (Van Duzee 1897). The male was designated lectotype by Oman (1947), and at the time both specimens were located in the collection at Iowa State (ISUC). Primary types were subsequently transferred to the National Museum of Natural History (USNM). The lectotype could not be located at either ISUI or USNM, but the female paralectotype was at ISUI.</p><p>Beamer (1950: 70) described Spartidelphax penedetectus as having "...crown about one-third longer than basal width instead of as wide as long and distinctly narrowed toward apex. Length ♂2.5 mm, ♀3 mm" (for brachypters). Beamer (1950) redescribed Spartidelphax detectus did not report body lengths except by quoting Van Duzee (1897: 248), who specified male 3½ mm, female 4 mm for the macropterous syntypes (yielding a length comparison between brachypterous penedetectus and macropterous detectus). Here we clarify that penedetectus is the larger species ( detectus brachypterous males 2.28 mm, macropterous males 3.29 mm, vs. penedetectus brachypterous males 2.33 mm, macropterous males 3.78), although body length does broadly overlap between species. The vertex l:w ratio is approximately 1.25-1.31 for detectus and 1.34-1.48 for penedetectus . For penedetectus Beamer (1950) also noted that crown is narrowed toward the apex. This feature seems valid for the paratypes from Cedar Keys (vertex width near base 0.25, at apex 0.16 versus average measurements of 0.23 near base and 0.22 near apex for detectus), but not for other specimens examined.</p><p>The most definitive feature that distinguishes the two species is the aedeagus (Fig. 4B, D). In Spartidelphax detectus the aedeagus has rows of small teeth on both sides of the apical third, tracing the curve of the aedeagus, with one row extending nearly to the expanded basal portion of the aedeagus. In Spartidelphax penedetectus, the aedeagus bears a pair of rows of ventral aedeagal teeth, reduced to fine serrulations in the type series.</p><p>Raupp and Denno (1979) found that the density of Spartidelphax detectus on Spartina patens exceeded 400 per kg of live grass sampled over a 6-month period, and was described as a dominant herbivore on Spartina patens by Denno (1977). It appears to have 3 non-synchronous generations per year in New Jersey, and overwinters as 4th or 5th instar (Denno 1976, 1977). Populations are wing polymorphic (both brachypters and macropters present within a population), with proportions of wing brachyptery and macroptery varying based on complex interactions of seasonal, environmental and population variables. An overall annual brachyptery rate of 86% (out of 23,868 specimens) was reported by Denno (1980) in New Jersey. Denno (1980) described niche differentiation among sap-feeding taxa on Spartina patens, including Spartidelphax detectus .</p><p>Type material examined.</p><p>Paralectotype.
