TL;DR: This study provides a framework for future use of molecular gut analysis in arthropod conservation ecology and food web research with considerable potential for quantifying threats to endemic species in Hawaii and elsewhere.
Abstract: Alien invertebrate predators have been introduced to Hawaii to control pests, particularly in lowland areas where most crops are grown. We developed techniques for assessing the impact of these predators on native food webs in relatively pristine upland areas where, it was hypothesized, few lowland predators might be found. Predator densities were assessed along transects within the Alakaii Swamp on Kaua’i. The most numerous alien biocontrol agents found were Halmus chalybeus (Coccinellidae), a species known to feed on Lepidoptera eggs. Laboratory experiments were conducted using two genera of endemic Lepidoptera, Scotorythra and Eupithecia (Geometridae), that are of considerable conservation value, the former because of its recent speciation across Hawaii, the latter for its unique predatory larvae. Techniques were developed for detecting Lepidoptera DNA within the guts of alien predators using prey-specific PCR primers. General primers amplified fragments of the mitochondrial cytochrome oxidase I gene from beetles and Lepidoptera. The sequences were aligned and used successfully to design target-specific primers for general detection of the remains of Geometridae and for particular species, including Scotorythra rara and Eupithecia monticolans. DNA fragments amplified were short [140– 170 base pairs (bp)], optimizing detection periods following prey ingestion. Trials using the introduced biocontrol agent Curinus coeruleus (Coccinellidae) demonstrated detection of Lepidoptera DNA fragments = 151 bp in 85–100% of beetles after 24 h digestion of an early instar larva. This study provides a framework for future use of molecular gut analysis in arthropod conservation ecology and food web research with considerable potential for quantifying threats to endemic species in Hawaii and elsewhere.
TL;DR: A new species of the geometrid genus Eupithecia is described from Spain: E upithecia gypsophilata sp.
Abstract: A new species of the geometrid genus Eupithecia is described from Spain: Eupithecia gypsophilata sp n This species belongs to the graphata species group and is somewhat similar externally to Eupithecia gemellata Herrich-Schaffer, 1861

Abstract: A new Eupithecia Curtis (Lepidoptera, Geometridae) species in the fletcherata group; Eupithecia nemrutica sp. n. is described from Turkey. Male and female adults, genitalia and habitats of the species are illustrated. The species is compared with Eupithecia jizlensis muelleri Hausmann, 1991.
TL;DR: The conservation of secondary forest remnants and natural forest appears to be essential for the survival of the very species-rich Andean geometrid moth communities.
Abstract: The diversity and faunal composition of geometrid moths (Lepidoptera: Geometridae) was investigated at two sites within an anthropogenically disturbed habitat mosaic at 1950 m and 2005 m a.s.l., in the vicinity of intact Andean montane rainforest in southern Ecuador. A total of 629 specimens belonging to 197 species were collected. The results were compared with those from ten sites of undisturbed forest habitats within an elevational range of 1800-2212 m. The local diversity of the moths at disturbed sites was surprisingly high (Fisher's alpha: 86.1 and 86.8; rarefied species number at the level of 250 specimens: 117 and 113; extrapolated species number, estimator Chao 1: 220 and 303). Forest successions and remnants probably serve as habitats for many species, but diversity is possibly overestimated due to the presence of 'tourist species' from adjacent forests. Disturbed habitats were characterized by a low diversity in the genera Eois, Bonatea and Herbita, probably due to the absence of their potential host plants (e.g. Piper species). Only three moth species represented by more than three individuals were found exclusively in disturbed habitats (Eupithecia densicauda, Pero obtusaria, 'Sabulodes' muscistrigata). Some 25 species profited from disturbance, among these were six species of the genus Eupithecia. The proportion of species present with only one specimen was high (56 and 62%), and species dominance was low (Berger- Parker index: 7.9 and 5.8%). In two-dimensional scaling based on the CNESS index of dissimilarity, disturbed sites are separated from the forest sites. The conservation of secondary forest remnants and natural forest appears to be essential for the survival of the very species-rich Andean geometrid moth communities.
TL;DR: Constant high values of spatial turnover across 17° of latitudinal gradient may indicate that diversity has been formed by a consistent mechanism of horizontal species level diversification of larentine moths throughout mountains.
Abstract: Biodiversity hotspots have been in the mainstream of studies and debates regarding conservation and biodiversity. Results, however, are skewed towards vertebrates and the tropics, and cannot simply be generalized to invertebrates and temperate biodiversity hotspot regions. In this first study of its kind, we explored the spatial patterns of Larentiinae moth (except genus Eupithecia Curtis, 1825) species richness and beta diversity in two neighbouring temperate biodiversity hotspots, the Caucasus and the Irano-Anatolian biodiversity hotspots, Middle Palearctic. We explored how spatial gradients contribute to the formation of moth species richness in these two biodiversity hotspots by disentangling beta diversity patterns to spatial turnover and nestedness components. Larentiinae moths showed a positive association with latitude and a unimodal relationship with elevation. The latitudinal gradient contributed more than the elevational gradient in formation of biodiversity. Both hotspots showed similar patterns of beta diversity partitioning, demonstrating a large contribution of spatial turnover to biodiversity formation. Constant high values of spatial turnover across 17° of latitudinal gradient may indicate that diversity has been formed by a consistent mechanism of horizontal species level diversification of larentine moths throughout mountains.
