HOLOTYPE: MALE: ‘‘ MEXICO: Oaxaca 9 mi. n. C. Loxicha [15.867636 N 96.468936 W, 1324 m], July 15–16, 1973, Mastro and Schaffner’’ ( AMNH _ PBI 00118408 ) . Holotype Slaterocoris maculatus n. sp. det. M.D. Schwartz, 2010 [red label]. Deposited in the collection of the Instituto de Biologia , Universidad Nacional Autonoma de Mexico, Mexico City, D.F .

DIAGNOSIS: Recognized by the brownishorange coloration on the head (pl. 2) and legs (fig. 13), particularly on the frons, mandibular and maxillary plates, the basolateral half of antennal segment I, coxae, trochanters, femora, except for diffusely delineated darker brown apices, and mostly dark brown tarsomeres I and II; the vestiture of golden brown, moderately long, suberect simple setae; and the male genitalia consisting of right paramere with long basal spine and three large terminal spines (fig. 61E), endosomal spicule with ventral and dorsal lobes bifurcate (fig. 61A), and the large medial tergal process (fig. 61F). Distinguished from S. clavatus , the only other Slaterocoris species with pale markings on the frons, by the diffusely delineated pale coloration of the femora (fig. 13); in S. clavatus , the pale markings on the head are restricted to the medial margin of the eye and base of the maxillary plate, and the femora are whitish yellow and sharply delineated (fig. 13).

DESCRIPTION: Male: Large, elongate, length 5.30, width 2.05; costal margin subparallel (pl. 2). COLORATION: Shining black; brown to brownish orange on head except black on basal carina, vertex, and clypeus; brownish orange on labium and antennal segment I, laterobasally; orange yellow; on coxae, trochanters, most of femora, except for apices, and tarsomeres I and II; dusky yellowish brown on tibiae (fig. 13). VESTITURE: Moderately distributed, moderately long, suberect, golden brown simple setae. DORSAL SCULPTURATION: Frons striate, vertex faintly rugose; calli faintly rugose, pronotal disc deeply rugulopunctate. STRUCTURE: Eye large, interocular distance of vertex narrow; labium reaching posterior margin of mesosternum. GENITALIA: Pygophore: Narrow, medial tergal process, reaching just beyond apex of proctiger (fig. 61F). Phallotheca: Left dorsal notch broadly U-shaped (fig. 61B). Endosomal spicule: Dorsal lobe bifurcate with serrate and smooth margined processes; ventral lobe recurved, bifurcate with serrate margined processes (fig. 61A). Right paramere: With long basal spine, length subequal to length of paramere apical to spine; apical region trifid, with large dorsal and ventral spines (fig. 61E). Left paramere: Shaft short, in apical view approximately one-half length of paramere body in lateral view (fig. 61C, D).

Female: Large, obovate, length 5.18–5.40, width 2.08–2.35 (pl. 2); otherwise similar to male, except for vertex distance shorter and eye small. COLORATION: Sometimes black on head restricted to clypeus and triangular patch on vertex. GENITALIA: First gonapophyses: Left overlapping right, in ventral view, comparative size at overlap with left greater than right. Left first gonapophyses: Dorsal surface concave, apex broadly convoluted. Vestibulum, anteroventral margin of anterior wall: Widely sclerotized medially, with sclerotized reaching lateral margins of bursa copulatrix. Ventral labiate plate: Strongly produced ventrally into vulva, moderately wide and triangular at base. Second gonapophyses: Anterior medial surface sclerotized and convex anteriorly (fig. 62A, B). Interramal sclerite: Dorsomedial region flat, not produced anteriorly, medial sclerite with narrowly tumid process abutting ovipositor bulb, and ventromedial region weakly overlapped by lateral sclerites of interramal sclerite and second gonapophysis basally (fig. 62A, B). Interramal lobe: Broad, with broadly protruding, curved medial margin and with moderately long, narrow, more dorsal lobe; ventral (anterior) margin with moderately long, attenuate, marginal serrate apex; median and ventral apices approximately equal in length (fig. 62A, B).

ETYMOLOGY: From the Latin macula, ‘‘ spot,’’ for the conspicuous pale portions of the head.

HOSTS: Unknown.

DISTRIBUTION: Five specimens are known from a July collection event at the type locality on the west end of the Sierra Madre del Sur in southern Oaxaca, Mexico ( map 12 ).

DISCUSSION: Leg coloration is somewhat similar in S. pallipes (3-3, 4-3, 5-3) and S. maculatus (3-3, 4-2, 5-2), although the tibiae of the latter are more darkened. Within the punctatus group, S. maculatus and S. punctatus are hypothesized to be sister species with homoplasious support contributed by the moderate densely distributed dorsal vestiture (10-1) and the strongly sclerotized and wide anterior wall of the vestibulum (57-5) (also present in S. clavatus ) in the female genitalia; under fast optimization, the brown dorsal vestiture (9-2) also provides ambiguous support.

PARATYPES: MEXICO: Oaxaca: 9 mi N of Candelaria Loxicha, 15.867636 N 96.468936 W, 1324 m, 15 Jul 1973 – 16 Jul 1973, Mastro and Schaffner, 1♀ (00093262) (CNC), 3♀ (00093261, 00093263–00093264) (TAMU).
