NEW SYNONYMY.  DIAGNOSIS: This the only species of  Slaterocoriswith dense, long, erect, brown dorsal vestiture. Distinguished from  S. alpinusand  S. hirtusby the arcuate costal margins of both sexes, particularly in the ovoid female, the erect dorsal vestiture, and the male genitalia with predominantly smooth margins of the endosomal spicule (also see Diagnosis under  hirtusgroup).  REDESCRIPTION: Male:Moderately large, ovate; length 3.80–4.50, width 2.10–2.30 (pl. 2, fig. 50C). COLORATION: Black; antennal segment II dusky brownish yellow; femur with apex pale, tibia dusky yellowish brown, paler distally, sometimes hind tibia mostly black, but median surface always paler, tarsomeres pale, except for terminal segment distally darkened (fig. 12). VESTITURE: Dense, long, erect, brown simple setae; setae somewhat unkempt (pl. 4J, 50C). STRUCTURE: Costal margin slightly arcuate (fig. 50C). GENITALIA: Endosomal spicule: Distal portion of ventral lobe long, narrow, with sparse or absent marginal serration (fig. 55D); dorsal lobe with base bifurcate with larger, flat, marginally smooth lateral ramus and short and marginally smooth medial ramus (fig. 55A, B, D arrow); rami narrow and sometimes of similar length (fig. 55C, arrow). Right paramere: Medial process removed from parallel apical spines, prominent, broad basally, slightly bent distally, with strong serration mostly on distal surface; tubercle basal to parallel spines, clearly separated from parallel spines, prominent, without serration (figs. 54B–E, 55G); sometimes parallel apical spines reduced and attenuate (fig. 54A, F).  Fig. 55.  Slaterocoris mohri, male genitalia. A, H.

Localities for  Slaterocoris alpinus,  S. hirtus, and  S. mohri.  Female:Moderately large, ovate; length 3.90–4.60, width 2.25–2.58 (pl. 2). STRUCTURE: Costal margin convex. GENITALIA: As in species group except: Second gonapophyses: With anterior medial surface strongly convex.  HOSTS: Unknown, although rosinweed,  Silphiumsp. (Asteraceae), is the breeding host of the related species  S. hirtus.  DISTRIBUTION: As currently known not as widely distributed as  S. alpinusand  S. hirtus, extending from southern Wisconsinsouth through Missourito western Arkansasinhabiting transitional prairie (grassland or savanna) and forest habitats (map 11).  COLLECTION SUMMARY: 45 specimensfrom 21 collection events. The phenology ranges from May through July.  DISCUSSION: Knight (1970)described  S. fuscicornisbased on the female holotypeand single male and female paratypesfrom Missouri, suggesting that antennal segment II was longer (exceeding the head width) than in  S. mohriand that the structure of the right paramere was species specific. My examination of the type material, particularly the male paratype( allotype) of  S. fuscicornis, indicates that it is identical to a male  S. mohriexamined by Kelton (1968). Antennal segment II is not longer than head width as claimed by Knight (1970)and although the right paramere is slightly different, it is well within the boundaries of infraspecific variation (cf. figs. 54D to 54A–C, E, F, 55G) of those specimens I consider to be  S. mohri. Based on measurements from across the range of  S. mohriantennal segment II length (1.09–1.20) in the male is usually longer than the head width (1.04–1.12); in the female antennal segment II is variable, either shorter or just longer than the head width (ratio HW/ AII, 0.98–1.07). Variation in the size and serration of the tubercle adjacent to the parallel apical spines of the right paramere accounts for the structure indicated by Knight (1970)as distinctive for  S. fuscicornis. The structure of the endosomal spicule in the nominal species  S. fuscicornisis identical to other specimens of  S. mohri(cf. fig. 55A, B– D). Based on my observations of the length of antennal segment II and the variation of the male genitalia, I consider  S. fuscicornisa junior synonym of  S. mohri. A male from Wisconsin, at the known northern limit of the species, has the most divergent structure examined of the right paramere (fig. 54A) and endosomal spicule (fig. 55C).  HOLOTYPES:  USA: Illinois:  Hancock Co.:Hamilton, 09 Jun 1932, Ross and Mohr, 1♀not examined (USNM) (  S. mohri: senior synonym).  Missouri:  Camden Co.:Camdenton [ 38.008056 N 92.744446 W, 318 m], 29 May 1960, J.C.
