A revision of the southern South American stag beetles of the genus Sclerostomus Burmeister (Coleoptera: Scarabaeoidea: Lucanidae)

Abstract

Four species of stag beetles in the genus Sclerostomus Burmeister from southern South America (composing the subgenera Chileistomus Weinreich and Sclerostomulus Weinreich) are redescribed: S. cucullatus (Blanchard), S. nitidus Benesh, S. tuberculatus (Solier), and S. varasi Nagel. A key to the southern South American genera of Lucanidae and species of Sclerostomus are provided to facilitate identification. The classification of the genus within the Lucanidae is discussed. Nomenclatural problems within Sclerostomus are resolved, and the generic concept is fixed through a lectotype designation for the type species, S. costatus [Westwood]. Lectotypes are also designated for S. cucullatus (Blanchard) and S. tuberculatus (Solier). A neotype is designated for S. varasi, a validly described but heretofore misidentified species. ResumenCuatro especies de los ciervos volantes del sur de Sudamérica en el género Sclerostomus (componiendo los subgéneros Chileistomus Weinreich y Sclerostomulus Weinreich Burmeister) son redescritas: S. cucullatus (Blanchard), S. nitidus Benesh, S. tuberculatus (Solier) y S. varasi Nagel. Se proporcionan claves para los géneros de Lucanidae del sur de Sudamérica y para el género Sclerostomus para facilitar su identificación. Se discute la posición del género dentro de Lucanidae. Se resuelven los problemas nomenclaturales en Sclerostomus y el concepto del género con la designación del lectotipo para la especie tipo, S. costatus [Westwood]. Se designan tambien lectotipos para S. cucullatus (Blanchard) y S. tuberculatus (Solier). Un neotipo se señala para S. varasi, una especie válida pero hasta ahora incorrectamente identificada.

Revision of the genus Lamprima Latreille, 1804 (Coleoptera: Lucanidae)

“…Arrow's casual remark "Westwood, in his anonymously published 'Catalogue of the Lucanoid Coleoptera' (generally attributed to Hope)" (Arrow 1936) may have been due to Boilieu or to his own observations of the annotated catalogues. However, since Arrow's comment, the catalogue has generally been cited as "Hope & Westwood" (Benesh 1960;Moore & Cassis 1992;Mizunuma & Nagai 2004;Holloway 2007;Hangay & de Keyzer 2017), or Hope only (Bouchard et al 2011). Paulsen (2005 Description.…”

A preliminary phylogenetic analysis of the New World Helopini (Coleoptera, Tenebrionidae, Tenebrioninae) indicates the need for profound rearrangements of the classification

“…Morphological characters were measured as follows: width of the head was measured across the vertex, length of the last antennomere in the female was measured along its longest edge; width was measured across its widest point; length of pronotum was measured along the midline from its anterior edge to its posterior edge; width was measured across its widest point. Puncture density follows modified conventions used by Paulsen (2005) and Smith et al (2011) : either confluent (separated by one or less than a puncture diameter), moderate (separated by 2–3 puncture diameters), or sparse (separated by 4 or more puncture diameters). Nomenclature and interpretation of female genital tract follows Tschinkel and Doyen (1980) and Doyen (1994) .…”

A revision of the Chilean tribe Lichniini Burmeister, 1844 (Coleoptera: Scarabaeidae: Melolonthinae)

“…12), especially abundant at Fundo Malcho, which used to be forested at the time when the specimens examined were collected. However, this area is now almost entirely deforested and has been developed into pine plantations (Paulsen 2005).…”
