   DOI:  10.5852/ejt.2018.404 


The vividly coloured Neotropical genus Callipia Guenée (1858) (Lepidoptera Linnaeus, 1758, Geometridae (Leach, 1815), Larentiinae (Leach, 1815), Stamnodini Forbes, 1948) is revised and separated into four species groups, according to a provisional phylogeny based on Cytochrome Oxidase I (COI) gene data and morphology. 

Fourteen new species are described using COI data and morphology:
a) in the balteata group: C. fiedleri sp. nov., C. jakobi sp. nov., C. lamasi sp. nov.;
b) in the vicinaria group: C. hausmanni sp. nov., C. walterfriedlii sp. nov.;
c) in the parrhasiata group: C. augustae sp. nov., C. jonai sp. nov., C. karsholti sp. nov., C. levequei sp. nov., C. milleri sp. nov., C. sihvoneni sp. nov., C. wojtusiaki sp. nov. and
d) in the constantinaria group: C. hiltae sp. nov., C. rougeriei sp. nov.
 One new subspecies is described: C. wojtusiaki septentrionalis subsp. nov. 

Two species are revived from synonymy: C. intermedia Dognin, 1914 stat. rev. and C. occulta Warren, 1904 stat. rev. 

The taxon hamaria Sperry, 1951 is transferred from being a junior synonym of C. constantinaria Oberthür, 1881 to being a junior synonym of C. occulta stat. rev. The taxon admirabilis Warren, 1904 is confirmed as being a junior synonym of C. paradisea Thierry-Mieg, 1904. The taxon languescens Warren, 1904 is confirmed as being a junior synonym of C. rosetta, Thierry-Mieg, 1904 and the taxon confluens Warren, 1905 is confirmed as being a junior synonym of C. balteata Warren, 1905. 

The status of the remaining species is not changed: C. aurata Warren, 1904, C. brenemanae Sperry, 1951, C. parrhasiata Guenée, 1858, C. flagrans Warren, 1904, C. fulvida Warren, 1907 and C. vicinaria Dognin. 

All here recognised 26 species are illustrated and the available molecular genetic information of 25 species, including Barcode Index Numbers (BINs) for most of the taxa is provided. The almost threefold increase from 10 to 26 valid species shows that species richness of tropical moths is strongly underestimated even in relatively conspicuous taxa. Callipia occurs from medium to high elevations in wet parts of the tropical and subtropical Andes from Colombia to northern Argentina. The early stages and host plants are still unknown.

Enneapterygius velatus sp. nov.
(New English name: Sail Triplefin; new Japanese name: Hotate-hebigimpo) 

Distribution. Currently known only from the Ryukyu Islands, southern Japan [Amami-oshima Island (Amami Islands), and Okinawa-jima and Kume-jima islands (Okinawa Islands)], the Okinawa-jima record being based on an underwater photograph taken at a depth between 30–41 m (Fig. 4). The species inhabits relatively deep reefs. The holotype was collected from a rubble bottom in the outer edge of coral reefs at a depth of 55 m.

Etymology. The specific name “velatus” is derived from Latin meaning “sail”, in reference to the high first dorsal-fin of the species.

[Ecology / Invasive Species • 2018] More Invaders Do Not Result in Heavier Impacts: The Effects of Non-native Bullfrogs on Native Anurans are Mitigated by High Densities of Non-native Crayfish

Liu, Wang, Ke, et al., 2018. 

1. With accelerating species introductions in an era of globalization, co-occurring alien species have become increasingly common. Understanding the combined ecological impacts of multiple invaders is not only crucial for wildlife managers attempting to ameliorate biodiversity loss, but also provides key insights into invasion success and species coexistence mechanisms in natural ecosystems. Compared with much attentions given to single-invader impacts, little is known about the impacts of multiple co-occurring invaders.
2. The American bullfrog (Lithobates catesbeianus Rana catesbeiana) and the red swamp crayfish (Procambarus clarkii) are two aquatic invasive species in many different areas of the globe. They coexist with native anurans in a variety of permanent lentic waters, which provide an ideal model system to explore the combined effects of multiple invaders from different trophic levels on native species.
3. Based on a global diet analysis covering 34 native and invasive bullfrog populations, and data from 10-year field surveys across 157 water bodies in the Zhoushan Archipelago, China, we observed a reduced impact of bullfrogs on native anurans at high crayfish densities when the two invaders co-occurred.
4. The global diet analysis showed that crayfish occurrence reduced the number of native anuran prey consumed by bullfrogs in both native and invasive populations. After accounting for pseudoreplication of different observations among water bodies, islands, and survey time, model averaging analyses based on GLMMs showed a negative relationship between bullfrog density and native anuran densities for field observations of invasive bullfrogs alone and co-invaded observations with low crayfish density. However, this negative relationship disappeared when the two invaders co-occurred with high crayfish density. Structural equation modelling (SEM) analyses further validated that the impacts of bullfrogs on native frogs were mitigated by the negative interactions between crayfish and bullfrogs.
5. Our results provide novel evidence of a density-dependent antagonistic effect of two sympatric invaders from different trophic levels on native species. This study highlights the importance of considering complex interactions among co-invaders and native species when prioritizing conservation and management actions and will facilitate the development of a more precise framework to predict invasion impacts.

[Entomology • 2018] Comprehensive and Dated Phylogenomic Analysis of Butterflies

in Espeland, Breinholt, Willmott, et al. 2018.

• Phylogenomic data provide a novel view of broad butterfly evolutionary relationships
• Most current diversity originated after the K-Pg mass extinction
• Many accepted higher taxa are para- or polyphyletic
• Ant association originated three times independently in blues and metalmarks

Butterflies (Papilionoidea), with over 18,000 described species, have captivated naturalists and scientists for centuries. They play a central role in the study of speciation, community ecology, biogeography, climate change, and plant-insect interactions and include many model organisms and pest species. However, a robust higher-level phylogenetic framework is lacking. To fill this gap, we inferred a dated phylogeny by analyzing the first phylogenomic dataset, including 352 loci (> 150,000 bp) from 207 species representing 98% of tribes, a 35-fold increase in gene sampling and 3-fold increase in taxon sampling over previous studies. Most data were generated with a new anchored hybrid enrichment (AHE) gene kit (BUTTERFLY1.0) that includes both new and frequently used (e.g., [6]) informative loci, enabling direct comparison and future dataset merging with previous studies. Butterflies originated around 119 million years ago (mya) in the late Cretaceous, but most extant lineages diverged after the Cretaceous-Paleogene (K-Pg) mass-extinction 65 mya. Our analyses support swallowtails (Papilionidae) as sister to all other butterflies, followed by skippers (Hesperiidae) + the nocturnal butterflies (Hedylidae) as sister to the remainder, indicating a secondary reversal from diurnality to nocturnality. The whites (Pieridae) were strongly supported as sister to brush-footed butterflies (Nymphalidae) and blues + metalmarks (Lycaenidae and Riodinidae). Ant association independently evolved once in Lycaenidae and twice in Riodinidae. This study overturns prior notions of the taxon’s evolutionary history, as many long-recognized subfamilies and tribes are para- or polyphyletic. It also provides a much-needed backbone for a revised classification of butterflies and for future comparative studies including genome evolution and ecology.

Our study confirms the power of phylogenomic approaches to resolve challenging arthropod phylogenetic relationships. Adding more than 340 genes to the 10 used previously and tripling the number of taxa included in previous studies confirmed some formerly poorly supported nodes and indicated many novel relationships. A well-supported phylogeny with broad coverage across tribes enables tests of existing hypotheses about higher-level relationships and identification of areas needing further study. Critically, it also serves as a needed scaffold for testing entirely new questions about the tempo and mode of butterfly evolution, such as associations between butterfly and plant clades and the impact of the K-Pg mass-extinction event. Moreover, the phylogeny provides the needed framework for broad comparative studies of the origins of key innovations, such as caterpillar-ant symbioses and other hypothesized drivers of lineage diversification, that have shaped the evolution of this highly studied insect group.

[Paleontology | Ichnotaxa • 2018] Sauripes hadongensis • Lizards ran Bipedally 110 Million Years Ago

Sauripes hadongensis Lee, Lee, Fiorillo & Lü, 2018

A reconstruction of a lizard running bipedally chased by the pterosaur 
Pteraichnus koreanensis, based on the trackway.  
Illustration: Chuang Zhao

Four heteropod lizard trackways discovered in the Hasandong Formation (Aptian-early Albian), South Korea assigned to Sauripes hadongensis, n. ichnogen., n. ichnosp., which represents the oldest lizard tracks in the world. Most tracks are pes tracks (N = 25) that are very small, average 22.29 mm long and 12.46 mm wide. The pes tracks show “typical” lizard morphology as having curved digit imprints that progressively increase in length from digits I to IV, a smaller digit V that is separated from the other digits by a large interdigital angle. The manus track is 19.18 mm long and 19.23 mm wide, and shows a different morphology from the pes. The predominant pes tracks, the long stride length of pes, narrow trackway width, digitigrade manus and pes prints, and anteriorly oriented long axis of the fourth pedal digit indicate that these trackways were made by lizards running bipedally, suggesting that bipedality was possible early in lizard evolution.

[Herpetology • 2018] Liolaemus absconditus • A New Species of the Liolaemus alticolor-bibronii Group (Iguania: Liolaemidae) from East-central Argentina

Liolaemus absconditus 
Vega, Quinteros, Stellatelli, Bellagamba, Block & Madrid, 2018

We describe a new species of Liolaemus of the L. alticolor-bibronii group of the subgenus Liolaemus sensu stricto. We studied meristic, morphometric and qualitative pattern characters. Statistical tests were performed in order to evaluate morphological differences among the candidate species and the most closely geographically distributed species. Molecular analyses of Cyt-b mitochondrial gene were performed in order to estimate the position of the new species in relation to other taxa. We also recorded natural history data such as habitat, behavior, reproductive state, diet, and body temperature. Liolaemus absconditus sp. nov. differs from other species of Liolaemus in presenting a distinct combination of morphological character states of lepidosis and color pattern, being phylogenetically close to Liolaemus tandiliensis, Liolaemus gracilis and Liolaemus saxatilis. The new species is a saxicolous and endemic lizard of the Tandilia Mountain Range System of Buenos Aires Province.

Hyperolius stictus 
Conradie, Verburgt, Portik, Ohler, Bwong & Lawson, 2018


A new species of African reed frog (genus Hyperolius Rapp, 1842) is described from the Coastal Forests of the Eastern Africa Biodiversity Hotspot in northeastern Mozambique. It is currently only known from less than ten localities associated with the Mozambican coastal pans system, but may also occur in the southeastern corner of Tanzania. Phylogenetic reconstructions using the mitochondrial 16S marker revealed that it is the sister taxon of Hyperolius mitchelli (>5.6% 16S mtDNA sequence divergence) and forms part of a larger H. mitchelli complex with H. mitchelli and H. rubrovermiculatus. The new species is distinguished from other closely related Hyperolius species by genetic divergence, morphology, vocalisation, and dorsal colouration.

[Ichthyology • 2018] A Euryhaline Fish, Lost in the Desert: The Unexpected Metapopulation Structure of Coptodon guineensis (Günther, 1862) in the Sebkha of Imlili, Morocco

Coptodon guineensis (Günther, 1862)

in Agnèse, Louizi, Gilles, et al., 2018. 

Euryhaline Cichlid fish of the species Coptodon guineensis are present in different water holes situated in a dried depression in the desert in the extreme South of Morocco, the Sebkha of Imlili. A genetic survey of this population, using complete sequences of the ND2 gene (mtDNA) and sixteen microsatellite loci, revealed that the fish in the sebkha did not form a single population, but rather a metapopulation. This metapopulational structure may be regarded as good news from the point of view of the conservation of fish in the sebkha. Although small individual populations may have short, finite life spans, the metapopulation as a whole is more stable, because immigrants from one population are likely to re-colonize the habitat, left open by the extinction of another.

[Crustacea • 2018] Rodriguezia adani • A New Species of Stygobitic Freshwater Crab of the Genus Rodriguezia Bott, 1969 (Decapoda: Trichodactylidae) from Tabasco, Mexico

Rodriguezia adani
Alvarez & Villalobos, 2018


A new species of freshwater crab of the family Trichodactylidae, genus Rodriguezia Bott, 1969 is described from Grutas de Agua Blanca in southern Tabasco, Mexico. Rodriguezia is a genus endemic to northern Chiapas and southern Tabasco, distributed over a small area of 70 km. Rodriguezia adani n. sp., the third species of the genus, occurs north of its two congeners, being stygobitic with obvious adaptations to cave life. It can be distinguished from R. villalobosi, an epigean species, by the absence of eyes, lack of pigmentation and elongation of the pereiopods; and from R. mensabak by having less elongated pereiopods relative to carapace breadth, an extremely reduced ocular peduncle, and a smaller adult size.
