Figures 1 , 2 , 4 , 6–9 , 11

HOLOTYPE: Male: MEXICO: Baja California Norte: 44.5 km E of Rt 1 toward Parque San Pedro Martin, 29.66666 ° N 101.34022 ° W, 720 m, 24 Apr 1985, R. T. Schuh and B. M. Massie, Salvia sp. (Lamiaceae) , 13 ( AMNH _PBI 00095219) ( UNAM).

DIAGNOSIS: Distinguished from Maculamiris insulanus , new species, by the red coloration (fig. 1), the slightly smaller vesica (fig. 4) and the left apical blade of the vesica less strongly bent and thus almost reaching the apex of the right blade, right blade slightly C-shaped.

DESCRIPTION: Male: As in generic description, total length 3.11–3.43, length from apex of clypeus to cuneal fracture 2.19–2.41, width across pronotum 0.92–1.02. COLORATION (fig. 1): General coloration red. Head: As in generic description with mandibular plate white, maxillary plate and gena red, labrum brown, base of antennal insertion suffused with red, and gula sometimes suffused with red; antenna as in generic description; labium as in generic description. Thorax: As in generic description with posterior pronotal lobe reddish, scutellum dark reddish brown, pleura reddish in part suffused with brown with whitish on margin of procoxal cavity and dorsal margin of propleuron, posterior rim of mesepimeron, dorsal margin of mesepimeron, and ventral portion of evaporatory area with exception of peritreme. Legs: As in generic description. Hemelytra: Corium with clavus red with irregular pale marks, anterior rim of corium proximally pale, cuneus with a proximal crescent-shaped transparent area, remaining part red. Abdomen: As in generic description, with venter and pygophore reddish brown and parameres brown. SURFACE AND VESTITURE (fig. 9D): Dorsum and hemelytra as in generic description. STRUCTURE: Head (fig. 2D, 4): Head including eyes, antennae, and labium as in generic description. Thorax: Thorax including hemelytra and legs as in generic description. Abdomen: As in generic description. GENITALIA (fig. 4): As in generic description, with left apical blade less strongly curved than in M. insulanus and thus almost reaching apex of right blade.

FEMALE (fig. 1): As in generic description. Total length 3.12–3.58, length from apex of clypeus to cuneal fracture 2.20–2.48, width across pronotum 0.91–1.09. GENITALIA (fig. 6): Vestibulum slender, S-shaped, bursal copulatrix short and broad, posterior margin with median evagination, sclerotized rings large and slender, medial margins rather close to each other.

ETYMOLOGY: Named for its distribution in Baja California, Mexico.

HOSTS: Recorded on Adenostoma fasciculatum A. & H., Rosa minutifolia Engelm. (Rosaceae) , and Salvia sp. (Labiatae) .

DISTRIBUTION: Recorded from Baja California Norte, Mexico, and Riverside and San Diego counties, California, United States (fig. 11).

DISCUSSION: Maculamiris baja is known from only few localities in Baja California Norte and mainland California. The closely related M. insulanus , new species, is known from four collecting events that account for only eight specimens from two of the Channel Islands, Santa Catalina Island, and San Clemente Island, California. Additional collecting, especially on the Channel Islands and in Baja California Norte, will help to elucidate if M. insulanus is an endemic of the southernmost Channel Islands, and if the closely related M. baja is actually restricted to mainland California and Baja California.

Thorax: As in generic description with posterior lobe light brown, scutellum dark brown, pleura dark brown with whitish on margin of procoxal cavity and dorsal rim of propleuron, posterior rim of mesepimeron, dorsal margin of mesepimeron, and ventral portion of evaporatory area with exception of peritreme. Legs: As in generic description. Hemelytra: Corium including clavus light brown with irregular whitish patches, cuneus with a proximal transparent area, remaining part pale yellow.
