Diagnosis. Carpophilus taylori resembles C. brachypterus but differs in its overall coarser punctation, genitalia differences, and disjunct distribution ( C. brachypterus is an eastern species, whereas C. taylori is currently only known from Arizona).

Description. Body weakly ovate, moderately dorso-ventrally flattened. Length 2.02 mm (1.96–2.14) (n = 4), width 0.88 mm (0.79–0.94) (n = 4). Color dark brown to black, pronotal margins and elytral humeri paler ( Fig. 1C ). Ventral surface dark brown. Dorsal sculpturing moderately shiny; dorsum with fine, golden pubescence. Head: Narrower than pronotum, finely punctured. Punctures uniform in size, becoming sparser at midline. Frontoclypeal region truncate, labrum emarginate, mandibles toothed, dark brown. Palpi fusiform, reaching about 2/3 length of mandibles. Eyes small, finely faceted, interocular distance 0.38 mm (n = 2). Antenna 1.5× longer than head; antennomere 1 robust and curved, antennomere 2 almost as long as basal antennomere, antennomere 3 smaller but longer than remaining antennomeres, antennomeres 2–8 expanding apically, antennomeres 3–8 each about half length of antennomere 2, antennomeres 9–11 forming strong, compact club that is slightly longer than wide. Pronotum: 1.67 times as wide as long, sides weakly rounded, anterior angles seemingly obtuse, posterior angles clearly broadly obtuse. Posterior margin with well-developed marginal line, particularly at middle, weakly sinuate. Disc flattened, moderately shiny, evenly and coarsely punctured. Scutellar shield: Feebly pentagonal, sides almost sinuate, reaching acute point posteriorly. Anteriorly finely granulated, gradually becoming glabrous. Elytra: Slightly wider than pronotum, width subequal to length. Humeri weakly pronounced. Anterior angles almost at right angles, sides mildly arcuate, posterior angles slightly acute, elytral apices gradually receding anteriorly towards midline. Abdomen: Two tergites dorsally visible, with fine, golden brown setae. Pygidium rounded with distinct, evenly spaced punctures. Venter: Overall paler, submentum narrow and transverse, antennal grooves well-developed. Prosternum coarsely punctate, punctures with a fine, golden seta, process slightly convex in lateral profile, apically rounded. Mesothoracic ventrite finely punctured. Metathoracic ventrite setose, finely punctate throughout. Abdominal ventrite 1 almost as long as metathoracic ventrite, abdominal ventrites 2–3 small, about 1/3 length of abdominal ventrite 1, finely, sparsely punctate, ventrites 4 and 5 large, granulated, more densely pubescent. Legs: Somewhat short, femora robust, covered with fine, golden pubescence.Tibiae expanded apically, with 5–7 apical spines. Male genitalia: Well-sclerotized; lateral lobes curved in dorsal view, forming narrow opening; in lateral view, lobes mildly curved to point ( Fig. 2C ), long sparse setae at apex. Ventrite 8 with acute anterior angles of outer margins that protrude past median lobe of ventrite.

Variation. Some variation occurs in overall coloration that can be slightly lighter, especially ventrally.

Geographic Distribution. The type series is known from the Huachuca and Chiricahua Mountains in southeastern Arizona, USA.

Biology. All specimens studied were captured using a flight intercept trap.

Etymology. The specific epithet honors the author’ s late grandfather, Roy Taylor. Not only was he a loving granddad, he also helped inspire the author’ s early love of the outdoors with his infamous “walks across the fields” in South Derbyshire, England.
