Description. Body parallel-sided, moderately convex dorsally (Fig. 1A). Length 3.3 mm (2.9–3.4) (n = 7), width 1.4 mm (1.2–1.5) (n = 7). Color black to dark brown, occasionally light brown, elytral humeri often lighter (Fig. 1A). Ventral body surface black to dark brown. Surface sculpturing on dorsal body surfaces moderately dull; fine pubescence golden brown to lighter yellow.
Head broad, narrowing behind eyes, coarsely punctured. Punctures uniform in size. Frontoclypeal region truncate and about a third the total width of the head. Mandible large, unidentate, darkening toward apex and internal margin. Maxillary palps simple, reaching just beyond mandibles. Eyes small, finely faceted, inter-ocular distance about 4 times the largest diameter of the eye in dorsal view. Antenna longer than head; antennomere 1 curved, as long as antennomeres 2 and 3 combined, antennomeres 2–8 expanded apically, with each apical expansion conspicuously lighter in color, antennomeres 2 and 3 about equal in length, 4–8 each about 0.5 times length of antennomere 2, antennomeres 9–11 forming strong, compact club, slightly longer than wide (Fig. 1B).
Pronotum 1.3 times as wide as long, sides nearly parallel, slightly wider at base, anterior angles obtuse and broadly rounded, posterior angles right. Posterior margin with weak marginal line, particularly weak at middle. Disc convex, moderately dull, evenly punctured. Scutellar shield feebly pentagonal, broadly rounded; anteriorly finely granulate, gradually becoming glabrous posteriorly.
Elytra about as wide as pronotum, also slightly wider than long at longest point when measured together. Humeri well-developed, lighter in color. Elytral anterior angles almost right, sides mildly arcuate, posterior angles more or less right, elytra obliquely truncate, forming a shallow V-shaped emargination. Two visible abdominal tergites with golden-brown setation denser than that on rest of dorsum.
Venter generally lighter in color. Submentum transverse and antennal grooves well-developed. Prosternum coarsely punctured; prosternal process slightly convex in lateral view, apically subtruncate, slightly rounded. Mesoventrite coarsely punctured with larger distance between each puncture than on prosternum. Metaventrite setose, finely punctate throughout.Abdominal ventrites 1–2 finely, sparsely punctate, ventrites 3–5 granulate, more densely pubescent and lighter brown. Pygidium rounded with distinct, evenly spaced punctures.
Legs relatively short, femora robust, covered with fine golden pubescence. Tibiae, especially metatibiae, expanded apically. Each tibial apex with two spurs and 2–4 articulated spines (Fig. 1C).
Male genitalia (Fig. 2A), well sclerotized; external and internal edges of the parameres strongly curved to sharp point, patch of long setae at apex.
Variation. In addition to the size variation summarized above, coloration varies from dark brown to almost black.
Distribution. The type series is known only from Victoria, Australia.
Biology. All specimens studied were captured in association with almond trees.
Etymology. The specific epithet is in reference to the aboriginal people that inhabited much of present-day Victoria. Jarijari is also the name for the language and in that language means “no”.
Diagnosis. This species is externally very similar to several species in the Carpophilus “ dimidiatus -group”; it differs, however, from C. australis Murray, C. davidsoni Dobson, C. dimidiatus (Fabricius), C. gaveni Dobson, C. maculatus Murray, C. mutilatus Erichson, and C. pilipennis MacLeay in the more exaggerated expansion of the hind tibia and the shape of the male genitalia; the apices of the parameres are more acute, and the lobes also lack the medial projection on the internal margins (Fig. 2C). Carpophilus jarjari differs from C. truncatus Murray in the shape of the parameres (Fig. 2C) and overall finer surface sculpturing.
