Figures 1 , 3 , 6

HOLOTYPE: Male : ‘‘[ USA] CA[alifornia]: Riverside Co., Palm Cyn, ca 5 mi S Palm Springs, VI­8–78, blk lite, John D. Pinto’ ’. Deposited in the American Museum of Natural History.

DIAGNOSIS: Recognized by the characters listed in the generic diagnosis, the strong sexual dimorphism, and the male being much longer and more nearly parallel­sided than the female (fig. 1). Adenostomocoris pintoi showing much less variation in pigmentation than A. semiustus , generally being a uniform greenish yellow. Female without, or with only a few, black setae on abdominal venter. The field of peglike setae on the posterior and ventral surfaces (figs. 5H) of the genital capsule pale, rather than black as in A. semiustus .

DESCRIPTION: Male: Moderately small, elongate; total length 3.35–3.77, length apex clypeus–cuneal fracture 2.12–2.40, width across pronotum 0.87–1.02. COLORATION (fig. 1): Greenish yellow. SURFACE AND VESTITURE (figs. 1, 5G): Peglike setae on ventral and posterior surface of genital capsule (fig. 5H) pale. STRUCTURE: Antennal segment 2 1.48 times as long as width of head. MALE GENITALIA (fig. 3): Vesica as in figure 3, differing from that of A. semiustus by the longer gonopore sclerite; phallotheca as in figure 3; left paramere as in figure 3.

Female: Moderately small; total length 2.73–2.99, length apex clypeus–cuneal fracture 1.96–2.11, width pronotum 0.95–1.03. COLORATION: As in male. SURFACE AND VESTITURE: As in male. STRUC­ TURE: Body form more strongly ovoid than in male; eyes smaller, frons more strongly bulging in dorsal view, head not appearing so strongly transverse (fig. 1).

ETYMOLOGY: Named for John D. Pinto, whose efforts in the field have done so much to broaden our knowledge of diversity, hosts, and distribution of Miridae in southern California and Arizona .

Arctostaphylocoris , new genus

Figures 1 , 3 , 7

TYPE SPECIES: Chlamydatus manzanitae Knight.

DIAGNOSIS: Recognized by the small size, deep brown to castaneous coloration, the hemelytra strongly deflexed at the cuneal incissure (fig. 1), dorsum broadly covered with recumbent, shining, simple setae, the clavus and corium adjacent to claval suture with flattened lanceolate setae (fig. 7C, D), and the sigmoid form of the male genitalia (fig. 3). Similar to some Chlamydatus spp. and to Pruneocoris , new genus, in small size and dark coloration. Distinguished from the former by the sharply carinate posterior margin of the vertex (fig. 7A); distinguished from both by the lanceolate form of the flattened setae on the hemelytra and the strong deflexion of the hemelytra at the cuneal incissure.

DESCRIPTION: Male: Small, broad­bodied, somewhat flattened, total length 2.13–2.39, length apex clypeus–cuneal fracture 1.51– 1.65, width across pronotum 0.83–0.94. COL­ ORATION (fig. 1): Largely deep brown to castaneous. SURFACE AND VESTITURE (figs. 1, 7C): Dorsum smooth, polished, shining, broadly covered with recumbent, shining, simple setae; clavus and corium adjacent to claval suture with flattened lanceolate setae (fig. 7C, D); distal portion of dorsal surface of hind femur lacking row of spinules as found in Atractotomus (fig. 7G, H). STRUC­ TURE: Head transverse, conforming to anterior margin of pronotum (figs. 1, 7A); posterior margin of vertex forming a weak carina (fig. 7A); ventral margin of antennal fossa at level of ventral margin of eye; head projecting below eyes by about one­third the height of an eye (fig. 7B); labium reaching well beyond trochanters, sometimes attaining anterior margin of genital capsule. Distal diameter of antennal segment 2 equal to diameter of segment 1, segment 2 distinctly tapering toward base (fig. 1). Costal margin of hemelytra distinctly rounded, convex, cuneal fracture conspicuously incised, hemelytra strongly deflexed at fracture (fig. 1). Claws of moderate length, claws smoothly curving, pulvilli moderately large and projecting from base of claw, parempodia setiform and attenuated (fig. 7F). Mesepisternal spicale and metathoracic scentgland evaporatory area as in figure 7E. Abdomen broad, tapering toward relatively small genital capsule, the latter occupying about one­half of length of abdomen. MALE GEN­ ITALIA (fig. 3): Vesica formed of a sinuously curving single strap attenuated apically; secondary gonopore well sclerotized, removed from apex by about the length of gonopore, gonopore sclerite lacking (fig. 3); phallotheca (fig. 3); left paramere boat­shaped, apex of anterior process heavily sclerotized; right paramere lanceolate.

Female: Small; total length 2.18–2.42, length apex clypeus–cuneal fracture 1.54– 1.66, width pronotum 0.80–0.94. COLOR­ ATION: As in male. SURFACE AND VES­ TITURE: As in male. STRUCTURE: As in male (fig. 1).

HOSTS: Arctostaphylos spp. (Ericaceae) .

DISTRIBUTION: Oregon to Arizona.

DISCUSSION: Knight (1964) included his new species manzanitae in Chlamydatus Curtis. Although similar in size and general appearance to some Chlamydatus species , manzanitae differs in the following characters: posterior margin of vertex forming a sharp ridge, whereas Chlamydatus spp. have the posterior margin rounded; and secondary gonopore with a projection or attenuation distally, whereas Chlamydatus spp. have the gonopore broadly and smoothly curving distally, with no projections. This species is therefore transferred to Arctostaphylocoris , new genus, and an additional new species is described from Arizona.

A number of features of our new genus are superficially similar to those of the Palearctic genus Salicarus Kerzhner, 1962 (type species Capsus roseri Herrich­Schaeffer, 1843 ). Kerzhner’s (1962) diagnosis of Salicarus mentioned that the body is broad, oval, and black with the hemelytra, head, and pronotum occasionally dark brown; the vestiture of the dorsum and sides of the thorax is a mixture of pale simple, and scalelike, setae; and the vesica is S­shaped with an undivided apex and a large almost terminally situated secondary gonopore. Although the host plants of Salicarus spp. belong to several plant families, most of the hosts are willows, ( Salix spp. ) ( Salicaceae ). The two species of Arctostaphylocoris are predominantly brown, clothed in mixed vestiture including flattened setae, have twisted vesicae with almost terminally located secondary gonopores, and inhabit Arctostaphylos spp. (Ericaceae) .
