Abstract Adult and immature stages of a new species, Brachys cleidecostae sp. nov., are described and illustrated. This species represents the first leaf-mining buprestid with two broad, prominent horn-like apophyses on vertex, resembling broad horns. The material was collected within unusual shaped leaf mines in Alibertia sessilis (Vell.) K. Schum (Rubiaceae), a native species from Brazilian Savanna (Cerrado). This is the first record of Brachys associated with a host plant of family Rubiaceae.

Abstract We present a brief biography of Dr. Cleide Costa, eminent entomologist from Museu de Zoologia da Universidade de São Paulo (MZUSP). She has been dedicating the last six decades to the study of adults and immatures of Coleoptera. Dr. Costa is the pioneer in collecting and rearing immature beetles in Brazil, being responsible for establishing the most extensive Latin American collection of reared immatures Coleoptera. We discuss central aspects of her personal history, as well as career landmarks and achievements. A compilation of taxa introduced to science by her, taxa named in her honor, and a full list of her scientific, educational and cultural production are provided in chronological order. More than a biographical account, this publication is an acknowledgment of Dr. Cleide Costa’s legacy to entomology.

A comparison between the two Brazilian species and a discussion, including intraspecific variations, are presented.

Neste trabalho é apresentada uma análise cladística de Dicrepidiina visando testar o monofiletismo da subtribo e estabelecer as relações entre os gêneros. A subtribo está formada por 36 gêneros e todos, exceto Asebis, Lamononia, Neopsephus, Semiotopsis e Spilomorphus foram incluídos na análise. Foram estudadas 52 espécies, principalmente as espécies-tipo de cada gênero: Achrestus flavocinctus (Candèze, 1859), A. venustus Champion, 1895, Adiaphorus gracilis Schwarz, 1901, A. ponticerianus Candèze, 1859, Anoplischiopsis bivittatus Champion, 1895, Anoplischius bicarinatus Candèze, 1859, A. conicus Candèze, 1900, A. haematopus Candèze, 1859, A. pyronotus Candèze, 1859, Atractosomus flavescens (Germar, 1839), Blauta cribraria (Germar, 1844), Calopsephus apicalis (Schwarz, 1903), Catalamprus angustus (Fleutiaux, 1902), Crepidius flabellifer (Erichson, 1847), C. resectus Candèze, 1859, Cyathodera auripilosus Costa, 1968, C. lanugicollis (Candèze, 1859), C. longicornis Blanchard, 1843, Dayakus angularis Candèze, 1893, Dicrepidius ramicornis (Palisot de Beauvois, 1805), Dipropus brasilianus (Germar, 1824), D. factuellus Candèze, 1859, D. laticollis (Eschscholtz, 1829), D. pinguis (Candèze, 1859), D. schwarzi (Becker, 1961), Elius birmanicus Candèze, 1893, E. dilatatus Candèze, 1878, Heterocrepidius gilvellus Candèze, 1859, H. ventralis Guérin-Méneville, 1838, Lampropsephus cyaneus (Candèze, 1878), Loboederus appendiculatus (Perty, 1830), Olophoeus gibbus Candèze, 1859, Ovipalpus pubescens Solier, 1851, Pantolamprus ligneus Candèze, 1896, P. mirabilis Candèze, 1896, P. perpulcher Westwood, 1842, Paraloboderus glaber Golbach, 1990, Proloboderus crassipes Fleutiaux, 1912, Propsephus beniensis (Candèze, 1859), P. cavifrons (Erichson, 1843), Pseudolophoeus guineensis (Candèze, 1881), Rhinopsephus apicalis (Schwarz, 1903), Sephilus formosanus Schwarz, 1912, S. frontalis Candèze, 1878, Singhalenus gibbus Candèze, 1892, S. taprobanicus Candèze, 1859, Sphenomerus antennalis Candèze, 1859, S. brunneus Candèze, 1865, Spilus atractomorphus Candèze, 1859, S. nitidus Candèze, 1859, Stenocrepidius simonii Fleutiaux, 1891 e Trielasmus varians Blanchard, 1846. Como grupos externos foram usados Chalcolepidius zonatus (Hemirhipini, Agrypninae), Ctenicera silvatica (Prosternini, Prosterninae), e algumas espécies de outras subtribos de Ampedini (Elaterinae): Ampedus sanguineus (Ampedina), Melanotus spernendus (Melanotina) e Anchastus digittatus e Physorhinus xanthocephalus (Physorhinina). Os resultados da análise filogenética demonstraram que Dicrepidiina, como definida anteriormente, não forma um grupo monofilético. Um gênero, representado por Ovipalpus pubescens, foi removido da subtribo. A subtribo está caracterizada pela presença de lamela no 2º e 3º tarsômeros de todas as pernas. Também está evidente que os gêneros Achrestus, Anoplischius, Dipropus e Propsephus não são monofiléticos. Devido à falta de informações sobre o grupo, todas as espécies estudadas são redescritas e ilustradas.

It is presented a cladistic analysis of the Dicrepidiina aiming to test the monophyletism of the subtribe and to establish the relationships among the genera. The subtribe is composed by 36 genera and all of them, except Asebis, Lamononia, Neopsephus, Semiotopsis and Spilomorphus were included in the analysis. Fifty two species, especially the type-species of each genus were studied: Achrestus flavocinctus (Candèze, 1859), A. venustus Champion, 1895, Adiaphorus gracilis Schwarz, 1901, A. ponticerianus Candèze, 1859, Anoplischiopsis bivittatus Champion, 1895, Anoplischius bicarinatus Candèze, 1859, A. conicus Candèze, 1900, A. haematopus Candèze, 1859, A. pyronotus Candèze, 1859, Atractosomus flavescens (Germar, 1839), Blauta cribraria (Germar, 1844), Calopsephus apicalis (Schwarz, 1903), Catalamprus angustus (Fleutiaux, 1902), Crepidius flabellifer (Erichson, 1847), C. resectus Candèze, 1859, Cyathodera auripilosus Costa, 1968, C. lanugicollis (Candèze, 1859), C. longicornis Blanchard, 1843, Dayakus angularis Candèze, 1893, Dicrepidius ramicornis (Palisot de Beauvois, 1805), Dipropus brasilianus (Germar, 1824), D. factuellus Candèze, 1859, D. laticollis (Eschscholtz, 1829), D. pinguis (Candèze, 1859), D. schwarzi (Becker, 1961), Elius birmanicus Candèze, 1893, E. dilatatus Candèze, 1878, Heterocrepidius gilvellus Candèze, 1859, H. ventralis Guérin-Méneville, 1838, Lampropsephus cyaneus (Candèze, 1878), Loboederus appendiculatus (Perty, 1830), Olophoeus gibbus Candèze, 1859, Ovipalpus pubescens Solier, 1851, Pantolamprus ligneus Candèze, 1896, P. mirabilis Candèze, 1896, P. perpulcher Westwood, 1842, Paraloboderus glaber Golbach, 1990, Proloboderus crassipes Fleutiaux, 1912, Propsephus beniensis (Candèze, 1859), P. cavifrons (Erichson, 1843), Pseudolophoeus guineensis (Candèze, 1881), Rhinopsephus apicalis (Schwarz, 1903), Sephilus formosanus Schwarz, 1912, S. frontalis Candèze, 1878, Singhalenus gibbus Candèze, 1892, S. taprobanicus Candèze, 1859, Sphenomerus antennalis Candèze, 1859, S. brunneus Candèze, 1865, Spilus atractomorphus Candèze, 1859, S. nitidus Candèze, 1859, Stenocrepidius simonii Fleutiaux, 1891 and Trielasmus varians Blanchard, 1846. Chalcolepidius zonatus (Hemirhipini, Agrypninae), Ctenicera silvatica (Prosternini, Prosterninae), and species of the other subtribes of Ampedini (Elaterinae): Ampedus sanguineus (Ampedina), Melanotus spernendus (Melanotina) and Anchastus digittatus and Physorhinus xanthocephalus (Physorhinina) were used as outgroups. The results of the phylogenetic analysis demonstrated that Dicrepidiina, as formerly defined, does not form a monophyletic group. One genus, represented by Ovipalpus pubescens, was removed from the subtribe. The subtribe is characterized by presence of lamella under 2nd and 3rd tarsomeres of all legs. Also, it was revealed that the genera Achrestus, Anoplischius, Dipropus and Propsephus are not monophyletic. Due to the scarcity of information, all the studied species are redescribed and illustrated.
