status

 

Psallus croceus Van Duzee, 1918: 302   (n.sp.).

DIAGNOSIS: Recognized by the weakly pinkish background coloration with conspicuous orange spots covering the entire dorsum (fig. 2), the relatively large size among Ceratopsallus spp.   , the average length 3.42, the distinct sexual dimorphism (males with larger eyes than females and cylindrical antennal segment 2), and the structure of the male genitalia, the vesica being moderately long (fig. 15), the phallotheca with a slender spine on the ventral surface, the left paramere with the right-hand prong of the anterior process erect and nearly straight, and the right paramere with the apical processes unequally developed, with the left process being distinctly longer than the right (fig. 15). Most similar to C. pantherinus (Van Duzee)   in the large eyes, cylindrical second antennal segment, and the pink-orange spots on the dorsum, but that species with antennal segment 2 much shorter, the vesica much longer, the ventral phallothecal spine flattened, and the right paramere with the apical processes of more or less equal length.

REDESCRIPTION: Male: Moderately large among Ceratopsallus spp.   , elongate, nearly parallel-sided, total length 3.15–3.70, length apex clypeus–cuneal fracture 2.19–2.48, width pronotum 0.98–1.19. COLORATION (fig. 1): Body and forewings pinkish; entire dorsum with a moderately dense covering of orange spots; eyes silvery or pale; coloration of appendages pale or weakly orange; membrane weakly to boldly marmorate, with a conspicuous large dark area posterior to the cuneus; veins of membrane pale. SURFACE AND VESTITURE (figs. 2, 13C): As in generic description. STRUC- TURE: Head: Eyes sexually dimorphic, large, vertex relatively narrow (fig. 2), eyes occupying nearly entire height of head; antennal segment 2 cylindrical, of uniform diameter over entire length, very long, length well more that 1.5 times width of head (ratio 1.06:0.73); labium long, surpassing hind trochanters by a short distance. GENITALIA (figs. 15): Vesica: Moderately long, slender, roughly J-shaped. Phallotheca: When viewed laterally bearing a short keel-like ridge on apicodorsal margin, spine on ventral margin slender, relatively long. Parameres: Left paramere with right-hand prong of anterior process very long, erect, nearly straight over much of length, left-hand prong relatively broad curving toward posterior process, posterior process of moderate length, nearly straight in lateral view, curving in dorsal view; right paramere long and broad, apical processes asymmetrically developed with left process much longer than right.

Female: Elongate ovoid; total length 3.03, length apex clypeus–cuneal fracture 2.11– 2.22, width pronotum 0.96–1.01. COLORA- TION (fig. 2): As in male. SURFACE AND VESTITURE: As in male. STRUCTURE: Hemelytra extending just beyond apex of

abdomen; eyes smaller than in male; antennal segment 2 tapered toward base. GENITA- LIA (fig. 15): See generic description.

HOST: Sycamore ( Platanus sp.   ) ( Platanaceae   ) ( Van Duzee, 1918).

DISTRIBUTION (map 3): Known from Riverside and Alpine Counties, California.

DISCUSSION: Van Duzee (1918) described Psallus croceus   from material ‘‘taken on a sycamore tree in Andreas’ Canyon at Palm Springs, Calif.’’ In his description he indicated that the right paramere was ‘‘long, curved and tapered, transverse, reaching across the genital segment’’. He did not mention the tubercle on the left side of the pygophore, although examination of the holotype indicates that it is present.

Ceratopsallus pantherinus (Van Duzee)   , new combination figures 2, 16; map 3

Psallus pantherinus Van Duzee, 1917: 279   (n.sp.).

DIAGNOSIS: Recognized by the weakly pinkish background with conspicous orange spots covering the entire dorsum (fig. 2), the relatively large size among Ceratopsallus spp.   , the average length 3.48, the distinct sexual dimorphism (males with larger eyes than females and cylindrical antennal segment 2), and the structure of the male genitalia, with the vesica being very long compared to other Ceratopsallus spp.   , the phallotheca with a flattened spine on the ventral surface, the left paramere with the right-hand prong of the anterior process smoothly curving, and the right paramere with the apical processes more or less equally developed (fig. 16). Most similar to C. croceus (Van Duzee)   in the large eyes and the pink-orange spots on the dorsum, but that species with antennal segment 2 much longer, the vesica much shorter, the ventral vesical spine slender, and the right paramere with the apical processes of unequal length.

REDESCRIPTION: Male: Moderately large among Ceratopsallus spp.   , elongate, nearly parallel-sided, total length 3.42–3.55, length apex clypeus–cuneal fracture 2.23–2.32, width pronotum 1.05–1.09. COLORATION (fig. 2): Body and forewings weakly pinkish; entire dorsum with moderately dense covering of orange spots; eyes silvery to red in available specimens; coloration of appendages pale or weakly orange; membrane weakly to boldly marmorate, with a large dark area posterior to the cuneus; veins of membrane pale.

STRUCTURE: Head: Eyes sexually dimorphic, large, vertex relatively narrow (fig. 2), eyes occupying nearly entire height of head; antennal segment 2 cylindrical, of uniform diameter over entire length, relatively short, length about onethird greater than width of head (0.90:0.70); labial apex obscured in all available specimens. GENITALIA (figs. 16): Vesica: Very long, filamentous, forming 2 complete coils (drawn to 50% of scale of congeners). Phallotheca: When viewed laterally with a broadly flattened apex, spine on ventral margin flattened, relatively long. Parameres: Left paramere with relatively short body, right-hand prong of anterior process smoothly curving and tapered toward apex, left-hand prong relatively short and narrow, posterior process relatively short, straight in lateral view, curving in dorsal view; right paramere moderately long and broad, apical processes symmetrically developed, of more or less equal length.

Female: Elongate ovoid; total length 3.02– 3.10, length apex clypeus–cuneal fracture 2.06–2.10, width pronotum 0.92–0.96. COL- ORATION (fig. 2): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra just covering abdomen; eyes smaller than in those of male, vertex relatively broad (figs. 2); antennal segment 2 tapered toward base. GENITALIA: Not examined.

HOST: Recorded from Quercus chrysolepis Liebm.   and Q. lobata Née   ( Fagaceae   ).

DISTRIBUTION (map 3): Distributed from Josephine County in southern Oregon and south through the northern coastal mountains to the foothills of the southern Sierra Nevada Mountains in California.

DISCUSSION: Van Duzee (1917) indicat- ed that he had described this species on the basis of specimens taken on Quercus agrifolia Née   near Cloverdale, Sonoma County   , California, and other material taken near Hoberg’s Resort, Lake County, California. He also mentioned having a single specimen from Manitou, Colorado. Van Duzee (1917) did not say whether the Hoberg Resort material was also taken on Quercus agrifolia   . I have examined the Manitou, Colorado, specimen; it belongs to Bisulcopsallus polhemorum   , n.sp.

COLORATION (fig. 2): Body and forewings faded green, often pale in preserved specimens; entire dorsum with moderately dense covering of greenish to brownish spots; eyes silvery to weakly reddish; coloration of appendages pale or greenish; membrane boldly marmorate, with a weakly developed continuous dark area posterior to the cuneus; veins of membrane pale. SURFACE AND VESTITURE (figs. 2, 13C): As in generic description. STRUCTURE: Head: Eyes lacking sexual dimorphism, vertex relatively broad (fig. 2), eyes occupying approximately two-thirds height of head; antennal segment 2 weakly tapered proximally (fig. 2); labium long, reaching hind trochanters, or surpassing them by a short distance. GENITALIA (figs. 17): Vesica: Moderately long, forming one complete loop. Phallotheca: When viewed laterally, with a triangular projection on the apicodorsal margin and a single slender spine on ventral margin. Parameres: Left paramere with left-hand prong of anterior process long and sinuously curving, right-hand prong also curving and projecting laterally away from the paramere body, posterior process of moderate length, nearly straight; right paramere with apical processes asymmetrically developed, the left process much longer than right.

Female: Elongate ovoid; total length 2.52– 3.24, length apex clypeus–cuneal fracture 1.79–2.24, width pronotum 0.85–0.98. COL- ORATION (fig. 2): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra extending just beyond apex of abdomen; eyes usually similar in size to those of male (figs. 2); antennal segment 2 tapered toward base. GENITALIA (fig. 17): See generic description.

ETYMOLOGY: Named for John D. Pinto, who during his tenure as a professor of entomology at the University of California, Riverside, collected and documented hosts for this and many other species of Miridae   from California and Arizona.

HOST: Recorded from Amelanchier alnifolia (Nutt.) Nutt.   , Cercocarpus betuloides Nutt.   , C. ledifolius Nutt.   , and Purshia tridentata (Pursh.) DC   ( Rosaceae   ), Ceanothus cordulatus Kellogg   , C. crassifolius Torr.   , C. greggii vestitus (Greene) McMinn   , and C. cuneatus (Hook.) Nutt.   ( Rhamnaceae   ), Eriodictyon angustifolium Nutt.   ( Hydrophyllaceae   ), and Quercus sp.   ( Fagaceae   ).

DISTRIBUTION (map 3): Widely distributed from Jackson and Klamath Counties in southern Oregon, south to Los Angeles and Riverside Counties in California, and east to Gila   and Mohave Counties, Arizona.

DISCUSSION: Based on available records, this is the most widespread species of

Ceratopsallus   , in terms of both geography and host preference. Nonetheless, the male genitalia are remarkably consistent in structure across the entire range of the taxon as here construed.

Ceratopsallus plautus   , new species figures 2, 18; map 3

DIAGNOSIS: Recognized by the cream to pale greenish coloration, the brownish spots on the dorsum restricted to the hemelytra and of more or less uniform size and distribution (fig. 2), the relatively small size among Ceratopsallus spp.   , the average total length 2.74, and the structure of the male genitalia, the vesica being J-shaped and relatively short, the phallotheca (in common with C. schwartzi   and C. vauqueliniae   ) bearing two spines, the one on the ventral surface slender, the other on the anterodorsal surface with a broad spoonlike apex, the left paramere distinctly flattened with the righthand prong of the anterior process erect and weakly curving apically, the posterior process of the left paramere being very long, slender, and smoothly curving downward, and the right paramere with the apical processes being more or less equally developed (fig. 18). Most similar to C. schwartzi   in the small size, lack of sexual dimorphism, and the form of the male genitalia, but easily distinguished by the slender apicodorsal spine on the phallotheca in C. schwartzi   ; distinguished from C. vauqueliniae   by the strong sexual dimorphism in the eyes and antennae of that species.

DESCRIPTION: Male: Relatively small among Ceratopsallus spp.   , elongate ovoid, total length 2.56–2.87, length apex clypeus– cuneal fracture 1.75–1.90, width pronotum 0.77–0.81. COLORATION (fig. 2): Body and forewings faded green or pale; brownish spots on the dorsum restricted to the hemelytra and of more or less uniform size and distribution; coloration of appendages pale or greenish; membrane boldly marmorate, with a conspicuous and continuous dark area posterior to the cuneus; veins of membrane pale. SURFACE AND VESTI- TURE (figs. 2, 13C): As in generic description. STRUCTURE: Head: Eyes lacking sexual dimorphism, vertex relatively broad (fig. 2), eyes occupying approximately twothirds height of head; antennal segment 2 weakly tapered proximally; labium reaching apex of hindtrochanters. GENITALIA (fig. 18): Vesica: Relatively short, J-shaped. Phallotheca: When viewed laterally with

a weak triangular projection on the apicodorsal margin, a slender spine on the ventral margin, and a second spine on the anterodorsal margin with a broad, spoonlike apex. Parameres: Left paramere distinctly flattened with the right-hand prong of the anterior process erect and weakly curving apically, posterior process of left paramere very long, slender, broadly curving downward; right paramere with apical processes of about equal length.

Female: Elongate ovoid; total length 2.68– 2.92, length apex clypeus–cuneal fracture 1.87–1.98, width pronotum 0.79–0.84. COL- ORATION (fig. 2): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra just covering abdomen; eyes usually similar in size to those of male (fig. 2); antennal segment 2 tapered toward base. GENITALIA (fig. 18): See generic description.

ETYMOLOGY: Named for the shape of the anterodorsal spine on the phallotheca. From the Latin, plautus   , broad.

HOST: Recorded from Arctostaphylos viscida Parry   and Arctostaphylos sp.   ( Ericaceae   ).

DISTRIBUTION (map 3): Known only from Wofford Heights, in the foothills of the Sierra Nevada Mountains, Kern County, California.

Ceratopsallus quercicola   , new species figures 2, 19; map 4

DIAGNOSIS: Recognized by the cream to weakly orange coloration of the dorsum, the more or less uniform covering of orangebrown spots on the dorsum being restricted to the hemelytra (fig. 2), the small to moderate size among Ceratopsallus spp.   , average total length 2.89, and the structure of the male genitalia, the vesica being Jshaped and short (similar in form to C. aquilonius   and C. schwartzi   ), the phallotheca when viewed laterally with a triangular projection on the apicodorsal margin and a single slender spine ventrally, the left paramere with the branches of the anterior process moderately long, smoothly curving, and forming a crescent, the posterior process relatively short, nearly straight in lateral view, and the right paramere with the apical processes asymmetrically developed, the left process distinctly longer than right (fig. 19). Similar in size and general appearance to C. plautus   and C. schwartzi   , although coloration in most specimens of C. quercicola   with a stronger suggestion of orange (rather than green), and by the structure of the male genitalia, including the left paramere and the phallotheca, with one phallothecal spine in C. quercicola   , rather than two as in the other two species.

DESCRIPTION: Male: Size moderate among Ceratopsallus spp.   , elongate ovoid, total length 2.83–2.97, length apex clypeus– cuneal fracture 1.88–2.02, width pronotum 0.86–0.93. COLORATION (fig. 2): Body and forewings faded green or pale; brownish spots on the dorsum of more or less uniform size and evenly distributed, either restricted to the hemelytra or covering entire dorsum; coloration of appendages pale or greenish; membrane boldly marmorate, with a weakly developed continuous dark area posterior to the cuneus; veins of membrane pale. SUR- FACE AND VESTITURE (figs. 2, 13C): As in generic description. STRUCTURE: Head: Eyes lacking sexual dimorphism, vertex relatively broad (fig. 2), eyes occupying approximately two-thirds height of head; antennal segment 2 weakly tapered proximally (fig. 2); labium reaching apex of hind trochanters. GENITALIA (fig. 19): Vesica: Relatively short, J-shaped. Phallotheca: When viewed laterally with a triangular projection on apicodorsal margin, apex flattened, a short, slender spine on ventral margin. Parameres: Left paramere with branches of anterior process smoothly curving, more or less lying in a single plane, posterior process relatively short, nearly straight in lateral view; right paramere with the apical processes unequally developed, the left process being distinctly longer than the right.

Female: Elongate ovoid; total length 2.64– 2.87, length apex clypeus–cuneal fracture 1.79–1.98, width pronotum 0.87–1.08. COL- ORATION (fig. 2): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra extending just beyond apex of abdomen; eyes usually similar in size to those of male (fig. 2); antennal segment 2 tapered toward base. GENITALIA: Not examined.

ETYMOLOGY: Named for its habit of feeding on at least one species in the genus Quercus Linnaeus   ( Fagaceae   ), among other plant groups.

HOSTS: Recorded from Arctostaphylos pungens Kunth   , Arctostaphylos sp.   ( Ericaceae   ), and Quercus oblongifolia Torr.   ( Fagaceae   ).

DISTRIBUTION (map 4): Known from moderate elevations in Riverside County, California, and from Cochise   and Pima Counties   in southern Arizona.
