Revision of the Genus Cyphura Warren, 1902. Part I: Introduction of the New Subgenus Xysterophora with Two New Species From Tijdschrift voor Entomologie 159 (2016) 143–163 Revision of the genus Cyphura Warren, 1902. Part I: Introduction of the New Subgenus Xysterophora with Two New Species from New Guinea (Lepidoptera: Uraniidae: Uraniinae) Siep Sinnema & Jannie Sinnema-Bloemen A new subgenus, Xysterophora, is introduced for the albisecta species group of the genus Cyphura Warren, 1902 (Lepidoptera: Uraniidae). Two new species are described: Cyphura (Xysterophora) devosi and C.(X). femkeae. The subspecies Cyphura atramentaria extensa Rothschild, 1915 is raised to species level. New combinations are formed for the species albisecta Warren, 1907, atramentaria Warren, 1907, extensa Rothschild, 1915, semialba Warren, 1907, and urapteroides Joicey & Talbot, 1917. Lectotypes are designated for the species albisecta, atramentaria, semialba, and urapteroides. Xysterophora is restricted to New Guinea.

Abstract: The tropical swallowtail uraniid moth Lyssa zampa is known to exhibit seasonal patterns of mass emergence throughout its range. These cyclical patterns of emergences are thought to correlate closely with oscillating host plant availability, as well as with interactions between herbivory and host plant defences. Because little has been reported concerning the biology of this species, the purpose of this paper is intended to serve as a starting point addressing the natural history of L. zampa in Singapore. Here we report on an instance of mass emergence of L.

The survey came about following a request from Tai Po Environmental Association. Recording, using ultraviolet light sources and live traps in four sub-sites, took place on the evenings of 24 April and 16 October 2009. In total, 825 moths representing 352 species were recorded. Of the species recorded, 3 meet IUCN Red List criteria for threatened species in one of the three main categories “Critically Endangered” (one species), “Endangered” (one species) and “Vulnerable” (one species” and a further 13 species meet “Near Threatened” criteria. Twelve of the species recorded are currently only known from Hong Kong, all are within one of the four IUCN threatened or near threatened categories listed. Seven species are recorded from Hong Kong for the first time. The moth assemblages recorded are typical of human disturbed forest, feng shui woods and orchards, with a relatively low Geometridae component, and includes a small number of species normally associated with agriculture and open habitats that were found in the SSSI site. Comparisons showed that each sub-site had a substantially different assemblage of species, thus the site as a whole should retain the mosaic of micro-habitats in order to maintain the high moth species richness observed.

Entomologie, Plantage Middenlaan 64, NL-1018 DH Amsterdam, The Netherlands Colin G. T readaway, Entomologie II, Forschungsinstitut Senckenberg, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany Abstract: This publication covers all Sphingidae known from the Philippines at this time in the form of an annotated checklist. (A concise checklist of the species can be found in Table 4, page 120.) Distribution maps are included as well as 18 colour plates covering all but one species. Where no specimens of a particular spe­ cies from the Philippines were available to us, illustrations are given of specimens from outside the Philippines. In total we have listed 117 species (with 5 additional subspecies where more than one subspecies of a species exists in the Philippines). Four tables are provided: 1) a breakdown of the number of species and endemic species/subspecies for each subfamily, tribe and genus of Philippine Sphingidae; 2) an evaluation of the number of species as well as endemic species/subspecies per island for the nine largest islands of the Philippines plus one small island group for comparison; 3) an evaluation of the Sphingidae endemicity for each of Vane-Wright’s (1990) faunal regions. From these tables it can be readily deduced that the highest species counts can be encountered on the islands of Palawan (73 species), Luzon (72), Mindanao, Leyte and Negros (62 each).

Toxopeus of Bandung, Java, sent me a specimen of Nyctalemon for identification, but neither with the help of our collection, nor with the current literature did I succeed in ascertaining the correct name of this insect. On the contrary it appeared that, though the described forms of this genus clearly were of different value, viz., partly good species, partly geographical subspecies representing these species in restricted areas, no satisfactory division of the genus into species and subspecies had been given. Thus, Seitz' classification of the known forms into four species of which three are polytypic proved to make no sense. Therefore I resolved to study the genus more closely. In the ensuing correspondence Toxopeus gave me the benefit of his experience by providing references to relevant literature and quotations from his own notes.

    Estonian Journal of Ecology, 2011, 60, 4, 321–327 doi: 10.3176/eco.2011.4.05 Rhopalodes lecorrei, a new moth species from French Guiana (Lepidoptera: Geometridae: Larentiinae: Trichopterygini) Jaan Viidalepp Institute of Agriculture and Environmental Studies, Estonian University of Life Sciences, Riia 181, 51014 Tartu, Estonia; [email protected] Received 12 September 2011, revised 3 November 2011 Abstract. A new species of geometrid moth, Rhopalodes lecorrei sp. nov. is described from French Guiana. The wing pattern, venation, and male and female genitalia of the new species are described, illustrated, and compared to allird species. Key words: Geometridae, Trichopterygini, new species, Rhopalodes lecorrei. INTRODUCTION Guenée (1858: 360, pl. 20, fig. 2) described a new genus and new species, Rhopalodes castniata Gn., basing on a single female specimen from Brazil. He paid much attention to the unique character of antennae, which are cylindrical, thickening from base to apex like in Castniidae and ending in a pointed tip just like in some Hesperiidae (Rhopalocera). In the descriptions of the following genera, Sauris Guenée and Remodes Guenée (Guenée, 1858: 361–364), the author paid attention to very long palpi of moths, to the presence of a ‘lobe appendiculaire’ in the males of the described species, but mentioned also the presence of one pair of spurs in the hind legs of Sauris (like in Rhopalodes) and the absence of spurs in Remodes. Snellen (1874: 77, pl. 6, fig. 2) presented the first description of a male from another species, Rhopalodes patrata Snellen, corrected one error by Guenée (concerning hind legs of Rhopalodes, which bear two pairs of spurs) and paid attention to the analogous shape of the antennae in the oriental species of Remodes.

Identification help was provided by Aaron Hunt, Steve Nanz, John and Jane Balaban, Chris Grinter, Frank Hitchell, Jason Dombroskie, William H. Taft, Jim Wiker,DQGTerry Harrison as well as others contributing to the websites. Attempts were made to obtain expert verifications for all photos to the field identification level, however, there will be errors. Please contact the author with all corrections Additional assistance was provided by longtime Lepidoptera survey partner, Susan Hargrove. The intention of these guides is to provide the means to compare photographs of living specimens of related moths from the Midwest to aid the citizen scientists with identification in the field for Bio Blitz, Moth-ers Day, and other night lighting events. A taxonomic list to all the species featured is provided at the end along with some field identification tips. :(%6,7(63529,',1*,'(17,),&$7,21,1)250$7,21 BugGuide.net LNaturalist.org Mothphotographersgroup.msstate.edu Insectsofiowa.org centralillinoisinsects.org/weblog/resources/ :+,&+027+*8,'(7286( The moths were split into 6 groups for the purposes of creating smaller guides focusing on similar features of 1 or more superfamilies.
