Summary
Description of the last larval instar (based on exuvia) of Anthrenus delicatus delicatus Kiesenwetter 1851, A. picturatus makolskii Mroczkowski 1950 and A. sophonisba Beal 1998 (Coleoptera: Dermestidae) is presented. Notes about the biology of A. picturatus makolskii and A. sophonisba are provided. Several morphological characters of Anthrenus larvae are documented: antenna, epipharynx, mandibula, maxilla, ligula with labial palpi, hastisetae, legs, terga, and condition of antecostal suture are documented, and discussed. Structural differences among mature larvae of the following Anthrenus species are compared and summarized: A. coloratus Reitter 1881, A. delicatus delicatus Kiesenwetter 1851, A. flavipes flavipes LeConte 1854, A. fuscus Olivier 1789, A. museorum (Linnaeus 1761), A. latefasciatus Reitter 1892, A. oceanicus Fauvel 1903, A. olgae Kalík 1946, A. picturatus makolskii Mroczkowski 1950, A. pimpinellae pimpinellae (Fabricius 1775), A. sarnicus Mroczkowski 1963, A. scrophulariae scrophulariae (Linnaeus 1758), A. sophonisba Beal 1998 and A. verbasci (Linnaeus 1767).
Résumé
Nous décrivons d'après les exuvies les derniers stades larvaires des sous-espèces Anthrenus delicatus delicatus Kiesenwetter Citation1851, A. picturatus makolskii Mroczkowski Citation1950 et de l'espèce A. sophonisba Beal Citation1998, ainsi que des détails sur la biologie d’Anthrenus picturatus makolskii Mroczkowski Citation1950 et d’A. sophonisba Beal Citation1998. Les caractères morphologiques suivants sont aussi présentés et discutés : antennes, epipharynx, mandibules, maxilles, ligules avec palpes labiaux, hastisètes, pattes, tergites, suture précostale. Les différences de structure entre les larves matures des espèces suivantes sont discutées: A. coloratus Reitter Citation1881, A. delicatus delicatus Kiesenwetter Citation1851, A. flavipes flavipes LeConte Citation1854, A. fuscus Olivier Citation1789, A. museorum (Linnaeus Citation1761), A. latefasciatus Reitter Citation1892, A. oceanicus Fauvel Citation1903, A. olgae Kalík Citation1946, A. picturatus makolskii Mroczkowski Citation1950, A. pimpinellae pimpinellae (Fabricius Citation1775), A. sarnicus Mroczkowski Citation1963, A. scrophulariae scrophulariae (Linnaeus Citation1758), A. sophonisba Beal Citation1998 et A. verbasci (Linnaeus Citation1767).
