New synonymies and notes in Criodion Audinet-Serville (Coleoptera: Cerambycidae: Cerambycinae)
(2021)
Criodion angustatum Buquet, 1852 a nd C. pilosum Lucas, 1857 (Coleoptera: Cerambycidae: Cerambycinae) are synonymized with C. tomentosum Audinet-Serville, 1834. The holotypes of C. angustatum and C. hirsutum, and syntypes of C. pilosum and of C. tuberculatum Gahan, 1892 are illustrated for the first time. One of the type localities of C. tuberculatum is corrected.
Hamaticherus Dejean, 1821 (Coleoptera: Cerambycidae: Cerambycinae) is considered a junior synonym of Cerambyx Linnaeus, 1758. Hamaticherus sensu Audinet-Serville, 1834 is considered a posterior usage of Hamaticherus Dejean, 1821, and an unavailable name. Plocaederus is considered as a new genus, and not a replacement name, proposed by Dejean (1835) to allocate the species included in Hamaticherus sensu Audinet-Serville, 1834. Therefore, a new genus, Hamaederus Santos-Silva, Garcia and Botero,is herein proposed to include the species currently allocated in Plocaederus Dejean, 1835, creating 15 new combinations, and additionally, a new species from French Guiana, Hamaederus allofasciatus Santos-Silva, Garcia and Botero, is described. Furthermore, Plocaederus barauna Martins and Monné, 2002 and Plocaederus confusus Martins and Monné,2002 are proposed as new junior synonyms of Hamaederus yucatecus (Chemsak and Noguera, 1997), and Hamaticherus bellator Audinet-Serville, 1834 is transferred to Plocaederus Dejean,
1835, new combination. New geographical records are provided for Hamaederus fraterculus (Martins), H. glaberrimus (Martins), H. rusticus (Gounelle), and H. yucatecus (Chemsak and Noguera). Hamaederus fasciatus is formally excluded from the fauna of French Guiana. A key to American genera of Cerambycina (Cerambycini) is provided.
Abstract. Six new species of Coleoxestia Aurivillius, 1912 (Cerambycidae, Cerambycinae, Cerambycini) are described: C. clarkei from Bolivia; C. chemsaki and C. eyai from Peru; C. fragosoi and C. rafaeli from Brazil; and C. hovorei from Ecuador. Coleoxestia rachelae Eya and Chemsak is also newly recorded from Peru (new country record). Dorsal, ventral and lateral illustrations along with illustrations of various other structures are provided for each of the new species. In some cases, existing key couplets by Eya and Chemsak (2005) or Martins and Monné (2005) are modifi ed to help separate a new species from similar existing species. A reproduction of the general descriptive terminology for the head, prothorax and antennomeres of Coleoxestia, from Fragoso (1993), is also included in the illustrations.
A new Mexican species of Ochraethes Chevrolat, 1860 (Coleoptera, Cerambycidae, Cerambycinae, Clytini) is described: Ochraethes skillmani Wappes, Santos-Silva and Botero. Plocaederus mirim Martins and Monné, 2002 (Cerambycini) is redescribed and its female is figured for the first time. New geographical records in Plocaederus Dejean, 1835 are also provided.
