Description of the last larval instar (based on larvae or exuviae) of Anthrenus (Helocerus) minutus (Erichson, 1848), Anthrenus (Nathrenus) biskrensis (Reitter, 1886), and Anthrenus (Nathrenus) signatus (Erichson, 1848; Coleoptera: Dermestidae) is presented. Morphological characters of Anthrenus larvae such as general morphology of antenna, epipharynx, mandible, maxilla, ligula with labial palpi, hastisetae, legs, and terga, and condition of antecostal suture, are documented and discussed. Structural differences among mature larvae of the following Anthrenus species are compared and summarized: Anthrenus coloratus (Reitter, 1881), Anthrenus delicatus delicatus (Kiesenwetter, 1851), Anthrenus flavipes flavipes (LeConte, 1854), Anthrenus fuscus (Olivier, 1789), Anthrenus museorum (L., 1761), Anthrenus latefasciatus (Reitter, 1892), Anthrenus oceanicus (Fauvel, 1903), Anthrenus olgae (Kalõ´k, 1946), Anthrenus picturatus makolskii (Mroczkowski, 1950), Anthrenus pimpinellae pimpinellae (F., 1775), Anthrenus sarnicus (Mroczkowski, 1963), Anthrenus scrophulariae scrophulariae (L., 1758), Anthrenus sophonisba (Beal, 1998), and Anthrenus verbasci (L., 1767). |
