Male genitalia, dorsal. 8. Bursa copulatrix sclerite. Description : Head: Dark brown, fine punctures with scattered larger round punctures, covered with decumbent pale hair; frons convex becoming flat toward anterior margin with well-developed apical carina; antennae just reaching the hind angles in males, not reaching the hind angles by about one antennomere in females; antennomere 2 subconical, slightly shorter than antennomere 3; antennomeres 3–10 feebly dilated at apex, longer than wide; antennomere 11 subellipsoidal, narrowed at apex. Pronotum: As long as wide, convex, widest at middle, dark brown to black, densely and finely round punctures with scattered larger round punctures, lateral margins arcuate; hind angles sharply truncate, carinate dorsally. Scutellum: Dark brown medially, more blackish along suture, slightly wider than long, heart- shaped, emarginate at base. Elytra: Yellowish-brown, medially shaded with black ( Fig. 6 ), covered with dense erect yellow setae, striae densely and finely punctate with scattered large rounded punctures, interstriae deeply punctate. Male genitalia : Parameres without a distinctly produced subapical rounded lobe, apicolateral expansion reduced, teardrop-like, two setae below expansion, distal setae long; median lobe simple, subparallel margins beyond middle apically narrowly rounded ( Fig. 7 ). Female genitalia : Proximal sclerite of the bursa copulatrix with 9–11 large marginal teeth, terminal teeth largest, and 11–13 smaller internal discal teeth including one just below large marginal terminal tooth ( Fig. 8 ). Etymology. The patronym honors Latifa A. Almutlaq. Diagnosis. Dicronychus latifae is most similar to D. brancuccii , but can be distinguished in the female by fewer teeth of the proximal sclerite of the bursa copulatrix ( Fig. 8 ). The parameres of the male genitalia lack the distinctly produced subapical rounded lateral lobe with the triangular expansions ( Fig. 7 ), as present in D. brancuccii ( Fig. 4 ). Additionally the apex of the median lobe is more narrowly rounded than either D. brancuccii ( Fig. 4 ) or D. bushrae n. sp. ( Fig. 10 ).
