DIAGNOSIS: In
A. scutellaris
(Chevrolat)
specimens, the largest specimens in this species group (
8 mm
), the elytra are conspicuously compressed laterally. There is an acute posthumeral lateral deflection that sharpens the humeral angle and gives the dorsal fascies of the elytra a subtrigonal appearance (figs. 41, 42).
DESCRIPTION:
Size
: Length
7.4–8.6 mm
; width
2.4–4.4 mm
.
Integument
: Black, antennal apex testaceous, tarsi piceous.
Vestiture
: Frontal, pronotal, metepisternal tufts well developed, epipleural tuft moderately developed, sutural tuft short but prominent; mesocutellum matted with white setae, elytral apical region in pale setae, remainder of dorsum sparsely vested with erect black setae; anterior fascies and apex of profemur vested with long, black setae, tarsi vested with black setae, pterothorax and abdomen vested with pale setae.
Head
: Gena and epicranium expanded; interocular depression and frontal umbo indistinct; frons, epicranium, and gena finely and sparsely punctate; eye subspherical, moderately convex; width across eyes slightly narrower than width across pronotum (60:63); antenna (fig. 84) elongate, nearly as long as length of pronotum (70:75).
Thorax
: Pronotum elongate (75: 63), disc finely wrinkled transversely in posterior region, finely punctate in remainder, side margins feebly arcuate, anterior transverse depression faintly indicated at sides, considerably narrower than width of elytra across humeri (63:85); elytra boldly convex and conspicuously compressed laterally especially behind the humerus, humeral angle pronounced, with 10 rows of very fine setiferous punctations, rows of punctations seem to coincide in position with faintly indicated longitudinal carinae, depth at humerus 30, greatest depth at posterior half 50; legs very prominently elongate, metafemur extended beyond elytral apex.
Abdomen
: Posterior margin of pygidium evenly arcuate in both sexes, tegmen as in figure 145; inner margins of parameres denticulate.
VARIATION: Elytral coloration varies from black to piceous and the basal half of the pronotal disc varies in the number and structural development of the transverse wrinkles. The antenna apex is less testaceous in some specimens. Also, there is some variation in the prominence of the transverse subapical depression of the pronotum, humerus, posthumeral margin, lateral coompression of the elytra, and longitudinal elevations of the elytral disc.
NATURAL HISTORY: Specimens were captured in June, July, and in September, at altitudes ranging from
914 to 1493 m
.
DISTRIBUTION (map 21): These specimens have been most abundantly collected from the Atlantic slopes of the Sierra Madre Oriental, but it is also known from the isthmus of Tehuamtepec.

REMARKS: In 1910, A. B. Wolcott published the name
Adelphoclerus nitidus
(
Wolcott, 1910: 357
)
which he later rejected as a secondary homonym of
Clerus nitidus
(
Chevrolat, 1843: 25
)
, and replaced it with the
Adelphoclerus fulgidus
(
Wolcott, 1927: 73
)
