Illiberis (Primilliberis) rotundata Jordan (Lepidoptera: Zygaenidae: Procridinae) male sex attractant: Optimization and use for seasonal monitoring

Illiberis (Primilliberis) rotundata Jordan, 1907 (Lepidoptera: Zygaenidae) is an orchard pest distributed in Honshu, Shikoku and Kyushu in Japan and also in China, Korea, Mongolia and Russia (south‐eastern Siberia and Far East). For optimizing a known sex attractant lure containing sex pheromone components of the species (2R)‐butyl (7Z)‐dodecenoate and (2R)‐butyl (9Z)‐tetradecenoate, field work was organized in three cherry tree plots in Naruto, Tokushima in 2009 and 2010. As a result, the mixture of (2R)‐butyl (7Z)‐dodecenoate and (2R)‐butyl (9Z)‐tetradecenoate in a ratio of 30:100–50:100 (130–150 µg, respectively) was found to be the most attractive for the males of this pest. The seasonal flight of I. rotundata in Naruto, Japan as estimated by pheromone traps started at the end of May and lasted up to the end of June with a mass flight at the very end of May to first week of June.     

Harnischia Kieffer from China,with Emendations to the Diagnosis of the Genus (Diptera: Chironomidae)

The genus Harnischia from China is revised. Harnischia cultriata sp.nov. is described as new to science from the male imago. H. hamata Wang et Zheng is recognized as new synonym of H. angularis Albu et Botnariuc and H. longispuria Wang et Zheng is recognized as a new synonym of H. curtilamellata (Malloch). A key to male imagines is presented. The distribution of the six known Chinese species is mapped. An emended generic diagnosis is given and discussed. Variation in the phallapodeme as an important specific diagnostic character within the genus is furnished.     

A new species of Phymatodes Mulsant (Coleoptera,?Cerambycidae) from China

A new species Phymatodes (Poecilium) latefasciatus sp. n. (Coleoptera, Cerambycidae, Cerambycinae, Callidiini) from China is described and illustrated. Features distinguishing the new species from its congeners are presented.     

Two new species of the orientalis group of Rheocricotopus (Psilocricotopus) from China (Diptera: Chironomidae)

Rheocricotopus (Psilocricotopus) calviculus sp. n. and R. (P.) villiculus sp. n. from China are described as male imagines. The species are closely related to the previously described R. (P.) orientalis Wang forming a new group, the orientalis group, which eventually may deserve the rank of subgenus or even genus. The group is distinguished by lacking a humeral pit, numerous sensilla clavata on third palpomere, cuneiform wings, no or few setae on squama, long legs, banded abdomen, very long inferior volsella, gonocoxite with apical extensions, and gonostylus with a median triangular projection.     

Genetic divergence of Platycerus hongwonpyoi (Coleoptera: Lucanidae) in South Korea

We examined the genetic divergence of Platycerus hongwonpyoi Imura & Choe, 1989 in South Korea using the nuclear wingless (Wg) gene, internal transcribed spacer (ITS) region and mitochondrial cytochrome oxidase subunit I (COI) gene. We found no variation in Wg or ITS. Based on COI, P. hongwonpyoi was split into four well defined and one weakly supported clades, which were inferred to have diverged 2.11–1.33 Ma. The Platycerus hongwonpyoi population size seems to have decreased during the past several tens of thousands of years. The divergence times of major clades of P. hongwonpyoi were comparable with those involved in the speciation of certain Japanese species. Frequent overlapping of different clades at the same sites suggests the occurrence of secondary gene flow following differentiation in South Korea. In conclusion, the genus Platycerus underwent strikingly different divergence patterns in South Korea compared with Japan according to the disparate topographies of these two geographical areas.

Photosynthetic pathway and ontogeny affect water relations and the impact of CO2 on Bouteloua gracilis (C4) and Pascopyrum smithii (C3)

The eastern Colorado shortgrass steppe is dominated by the C₄ grass, Bouteloua gracilis, but contains a mixture of C₃ grasses as well, including Pascopyrum smithii. Although the ecology of this region has been extensively studied, there is little information on how increasing atmospheric CO₂ will affect it. This growth chamber study investigated gas exchange, water relations, growth, and biomass and carbohydrate partitioning in B. gracilis and P. smithii grown under present ambient and elevated CO₂ concentrations of 350 μl l⁻¹and 700 μl l⁻¹, respectively, and two deficit irrigation regimes. The experiment was conducted in soil-packed columns planted to either species over a 2-month period under summer-like conditions and with no fertilizer additions. Our objective was to better understand how these species and the functional groups they represent will respond in future CO₂-enriched environments. Leaf CO₂ assimilation (A _n), transpiration use efficiency (TUE, or A _n/transpiration), plant growth, and whole-plant water use efficiency (WUE, or plant biomass production/water evapotranspired) of both species were greater at elevated CO₂, although responses were more pronounced for P. smithii. Elevated CO₂ enhanced photosynthesis, TUE, and growth in both species through higher soil water content (SWC) and leaf water potentials (Ψ) and stimulation of photosynthesis. Consumptive water use was greater and TUE less for P. smithii than B. gracilis during early growth when soil water was more available. Declining SWC with time was associated with a steadily increased sequestering of total non-structural carbohydrates (TNCs), storage carbohydrates (primarily fructans for P. smithii) and biomass in belowground organs of P. smithii, but not B. gracilis. The root:shoot ratio of P. smithii also increased at elevated CO₂, while the root:shoot ratio of B. gracilis was unresponsive to CO₂. These partitioning responses may be the consequence of different ontogenetic strategies of a cool-season and warm-season grass entering a warm, dry summer period; the cool-season P. smithii responds by sequestering TNCs belowground in preparation for summer dormancy, while resource partitioning of the warm-season B. gracilis remains unaltered. One consequence of greater partitioning of resources into P. smithii belowground organs in the present study was maintenance of higher Ψ and A _n rates. This, along with differences in photosynthetic pathway, may have accounted for the greater responsiveness of P. smithii to CO₂ enrichment compared to B. gracilis.

Taxonomic review of the genus Lymantria (Lepidoptera: Erebidae: Lymantriinae) in Korea

A taxonomic review of the Korean Lymantria Hübner, 1819 was conducted. A total of nine species of five subgenera with two unrecorded species are listed: Lymantria (Porthetria) dispar Linnaeus 1758, L. (P.) xylina Swinhoe 1903, L. (Lymantria) monacha (Linnaeus 1758), L. (L.) minomonis Matsumura 1933 (new to Korea), L. (L.) similis monachoides Schintlimeister 2004 (new to Korea), L. (L.) lucescens (Butler 1881), L. (Nyctria) mathura Moore 1865, L. (Collentria) fumida Butler 1877, and L. (Spinotria) bantaizana Matsumura 1933. Lymantria (Lymantria) minomonis and L. (L.) similis monachoides are newly added to the Korean fauna. Lymantria (L.) minomonis was found only on Bogildo Island of Jeollanam‐do in the southern part of Korea, and L. (L.) similis monachoides was collected in central Korea. Lymantria (Porthetria) xylina and L. (Collentria) fumida were not examined in this study, and it is considered that the previous records were due to misidentification or they are only distributed in the northern part of the Korean Peninsula. We provide diagnoses of two unrecorded species and adult habitus and genitalia photos of the Korean Lymantria species.
