Endogeophilus ichnusae gen. et sp. nov. (Chilopoda: Geophilidae sensu stricto) is described based on three specimens from two localities in south-western Sardinia, examined by light and scanning electron microscopy. The new centipede resembles the rare Ibero-Pyrenean genus Galliophilus Ribaut & Brolemann, 1927 in some features, especially in the forcipular segment, and the temperate European species Geophilus electricus (Linnaeus, 1758) in other features, especially in the ultimate leg-bearing segment. However, the true affinities of E. ichnusae gen. et sp. nov. are uncertain, because the new species departs significantly from the majority of geophilids for the higher number of legs (91–107 pairs in the specimens examined), the slender trunk segments (the sternites being longer than wide), the relatively stout legs (the tarsus being only about twice as long as wide) and the very short setae (≤ 15 mm) scattered on the body surface. All these features are probably derived and suggest adaptation to a more strictly endogeic habit than other geophilids.
The New World Clistopyga chaconi species group is revised. Eleven species are described as new: C. amazonica sp. nov., C. cinnamoptera sp. nov., C. cuscoensis sp. nov., C. hayesiana sp. nov., C. melanoptera sp. nov., C. misionensis sp. nov., C. mocaguae sp. nov., C. orellanae sp. nov., C. porteri sp. nov., C. rondoniae sp. nov. and C. yabuquensis sp. nov. Additional morphological data are provided for the previously known species, C. caramba Castillo & Sääksjärvi and C. chaconi Gauld. An illustrated identification key to all species of the group is provided. The Clistopyga chaconi species group appears to be most diverse at the Andean and Amazonian interface in western South America.
The description of a new species of Kessleria (Lepidoptera: Yponomeutidae) is presented, based on male and female specimens obtained from laboratory rearing of material collected on their host, Maytenus boaria, of the central region of Chile.
Epimelitta postimelina Giesbert, 1996 and Odontocera apicula Bates, 1885 are transferred to the new genus Odontomelitta. Epimelitta postimelina, with closed procoxal cavities, cannot remain in Epimelittta Bates, 1870, a genus characterized by open procoxal cavities. The short elytra and tegmen (with caliper-shaped lateral lobes) of the aedeagus of both species excludes them from the genus Odontocera Audinet-Serville, 1833, with long elytra and tegmen (with strap-shaped lateral lobes). Both species are illustrated, and host plant and host flower records provided for O. apicula.
Epimelitta Bates, 1870 (Coleoptera, Cerambycidae) is redescribed with two species: Epimelitta scoparia (Klug, 1825) and Epimelitta rufiventris Bates, 1870; Epimelitta meliponica Bates, 1870 syn. nov. and Epimelitta acutipennis Fisher, 1947 syn. nov. are considered junior synonyms of E. scoparia. Exepimelitta gen. nov. is described with five species: Exepimelitta mimica (Bates, 1873), Ex. nigerrima (Bates, 1892), Ex. consobrina (Melzer, 1931) (=Epimelitta nigerrima var. flavipubescens Fisher, 1947, syn. nov.), Ex. lestradei (Peñaherrera-Leiva and Tavakilian, 2003) and Ex. windsori sp. nov. Charisia Champion, 1892 is revalidated and redescribed with six species: Charisia euphrosyne (Newman, 1840), C. mneme (Newman, 1841), C. melanaria Gounelle, 1911, C. ornaticollis Zajciw, 1973, C. bleuzeni (Peñaherrera-Leiva and Tavakilian, 2003) and C. durantoni (Peñaherrera-Leiva and Tavakilian, 2003).
Erratamelitta gen. nov. is described with two species: Erratamelitta erato (Newman, 1840) (= Epimelitta bicolor (Bates, 1873), syn. nov.) and Er. eliasi sp. nov.. Adepimelitta gen. nov. is described with two species: Adepimelitta debilis (Gounelle, 1911) and Ad. eupheme (Lameere, 1884). A brief synopsis of the genus Acorethra Bates, 1873 is presented, with two species included: Acorethra chrysaspis Bates, 1873, revalidated, and Ac. aureofasciata Gounelle, 1911. All species are illustrated (including genitalia when available); and keys to the genera, and their species, are provided.
The genus-group taxon Megatrigon Johnson, 1898, stat. nov., is revised and treated as a valid genus within the Merodontini (= Eumerini). Extensive diagnoses are given for the genus and for its three constituent species groups: argenteus group [11 spp.], nivalis group [monotypic], sexfasciatus group [3 spp.]. Five new generic combinations are proposed within Megatrigon: M. argenteus (Walker, 1852) comb. nov., M. flavimarginatus (Hull, 1964) comb. nov., M. jacobi (Hervé-Bazin, 1913) comb. nov., M. nivalis (Hull, 1964) comb. nov. and M. ochreatus (Hull, 1964) comb. nov. All species of the argenteus group are revised and nine new species are described: Megatrigon apiformis sp. nov., M. argentifrons sp. nov., M. argentimaculatus sp. nov., M. cooksoni sp. nov., M. immaculatus sp. nov., M. magnicornis sp. nov., M. natalensis sp. nov., M. sexmaculatus sp. nov., M. tabanoides sp. nov. Within the sexfasciatus group, M. jacobi (Hervé-Bazin, 1913) comb. nov. is treated as a senior synonym of Eumerus connexus Hull, 1964 syn. nov., but no further work is done at the species level due to insufficient material.
We provide the current holdings of Meropeidae in the Florida State Collection of Arthropods (FSCA). To date, FSCA holds a well-curated collection of extant meropeids representing 17 U.S. states and Western Australia (n = 316 Merope tuber Newman, fi ve Austromerope poultoni Killington). Merope tuber records from Vermont, Texas, and South Carolina are published here for the fi rst time. A total of 298 pinned M. tuber and four pinned
A. poultoni; six M. tuber specimens preserved in 95% ethanol; and 12 M. tuber and one A. poultoni sputter-coated with gold-palladium for SEM are available for researchers interested in studying this unique family of insects.
Three new genera of Odontopygidae are described, all based on new species from the Udzungwa mountains, Tanzania, and all monotypic: Casuariverpa gen. nov. (type species: C. scarpa gen. et sp. nov.), Yia gen. nov. (type species: Y. geminispina gen. et sp. nov.), and Utiliverpa gen. nov. (type species: U. decapsulatrix gen. et sp. nov.). Similarities and differences between the new genera and other genera are discussed.
