NILSSON1 & IGNACIO RIBERA2 1Department of Ecology and Environmental Science, Umea˚ University, Umea˚, Sweden, and 2Departamento de Biodiversidad y Biologı´a Evolutiva, Museo Nacional de Ciencias Naturales, Madrid, Spain Abstract A fourth species of the Holarctic Ilybius angustior complex, Ilybius minakawai n. sp., is described from the Island of Sakhalin in the Russian far east. Male genitalia are diagnostic within this species complex, Downloaded By: [Umea University Library] At: 08:31 23 August 2007 although from body size and shape the new species cannot be separated from I. churchillensis Wallis from north Alaska and the Canadian low arctic. The small and narrow body characteristic of these two species represents an extreme of the cold climate form of the widespread I. angustior (Gyllenhal). Low variation within the studied large ribosomal and cytochrome c oxidase subunit I mitochondrial genes suggest that speciation events within the I. angustior-complex are fairly recent. In combination with known geographical ranges, the low genetic variation within this species complex suggest speciation within Pleistocene refugia including Beringia. Keywords: Diving beetles, Ilybius angustior, new species, Holarctic, mitochondrial DNA, species delimitation, Sakhalin Introduction The I. subaeneus-group of the genus Ilybius Erichson currently includes 32 species of which 18 are Palearctic, nine Nearctic and five Holarctic (Nilsson 2001). The species occurring in North America were revised by Larson (1987), and the West Palearctic species are more or less well-known (e.g. Nilsson & Holmen 1995). In contrast, many East Palearctic species remain poorly known. Nilsson (1994, 1999) revised the so-called I. crassus- and I. poppiusi- complexes, and we will here describe a new species in the Holarctic I. angustior-complex. The I. angustior-complex is very similar to the closely related I. poppiusi-complex (Ribera et al. 2004, represented by I. angustior (Gyllenhal) and I. anjae Nilsson, respectively), sharing the combination of ridged metatarsomeres and a carinate and rugose sternum 6 in males (Nilsson 1999). The two main differences are found in the smaller body size, and in the partly infuscate distal antennomeres of the species in the I. angustior-complex. Correspondence: Anders N.

Ribera The Holarctic distribution of I. angustior has been recognised already by Sharp (1882). A second species of the complex was described from North America by Kirby (1837) as Colymbetes picipes. Kirby’s species was synonymised with I. angustior by Branden (1885), and not until recently restored as a valid species with a Holarctic distribution (Persson 1985). The third species of the complex, the Nearctic I. churchillensis Wallis, was described from the Canadian low arctic (Wallis 1939). Species limits within this complex have been analysed chiefly by Larson (1987) and Larson et al. (2000) based on morphology. The three known species are poorly differentiated and difficult to separate. We will here describe a fourth species of the I. angustior-complex from the Sakhalin Island in the Russian far east, and provide mitochondrial DNA data for four of the six species of the two complexes. A single male of the new species was collected by S.K. Kholin in 1995, and a larger series was included in the material from the 2002 and 2003 expeditions to Sakhalin recently sent to the senior author by N. Minakawa. We also advance some hypotheses concerning the geographical and temporal origin of the species of the complex, based on the DNA sequence data. Material and methods Morphological analyses Body length was measured from the anterior margin of the head capsule to the apex of the elytra. Width of metasternum (WS) was measured inside marginal bead. Penis length was measured as in Nilsson (1999, Figure 15), and penis width was measured as the maximum Downloaded By: [Umea University Library] At: 08:31 23 August 2007 width of the penis shaft in lateral view. All statistical analysis were run using software Statistica 6.0. Longitude and latitude are given for all mapped localities. (CAN) Coll. Anders N. Nilsson, Umea˚ (CDB) Coll.

Morphometric data on Nearctic I. angustior (48 < 45 ,) and I. churchillensis (44 < 51 ,) corresponding to Figure 74 in Larson (1987) were received from Dr. D.J. Larson. Molecular methods Genomic DNA was obtained through a standard phenol-chloroform extraction using abdominal tissue of specimens collected in ethanol. Two fragments of mitochondrial genes were sequenced, the large ribosomal unit (rrnL) (ca. 500 bp) and the 30 end of the cytochrome c oxidase subunit I (cox1) (ca. 800 bp) (see Ribera et al. 2003 for details of the primers and conditions of the amplification). An additional fragment was sequenced for some of the specimens (Table I), spanning the 30 end of the rrnL gene, the tRNA-Leu and the 50 end of the gene NADH dehydrogenase subunit 1 (ND1), with the same forward primer as the small rrnL fragment and the reverse primer M223 (Simon et al. 1994) (30-GGTCCCTTACGAA TTTGAATATATCCT-50), amplifying a total of ca. 800 bp. Both forward and reverse sequences were obtained for each fragment, which were assembled and edited using Sequencher 4.2 (GeneCodes Corporation). New sequences

McLachlan Dorothy Jean Jackson FRES FLS (1892-1973) should be familiar to anyone interested in water beetles. She published prolifically on the ecology, distribution, flight capacity, and parasites of water beetles, and made especially important contributions to our knowledge of dytiscids. Lees (1974) provided a very brief and somewhat accurate obituary. I am currently preparing a more comprehensive biography of her and would be grateful to receive any notes or anecdotes from those that knew or met her. Foster (1991), at the request of the late Hans Schaeflein, was the first effort in putting together a publication list. Here I provide a more extensive bibliography of her work that is almost certainly incomplete, but I think includes most of her scientific output between 1907 and 1973.

An Analysis of Soviet Competitive Potentialities Skogsekonomi i Sovjet~rnionen rned en unalys av landets potentiella konkurrenskraft by KARL VIICTOR ALGTTERE SICOGSH~GSICOLAN ROYAL COLLEGE OF FORESTRY STOCKHOLM Lord Keynes on the role of the economist: "He must study the present in the light of the past for the purpose of the future." Printed in Sweden by ESSELTE AB STOCKHOLM Foreword Forest Economy in the U.S.S.R. is a special study of the forestry sector of the Soviet economy. As such it makes a further contribution to the studies undertaken in recent years to elucidate the means and ends in Soviet planning; also it attempts to assess the competitive potentialities of the U.S.S.R. in international trade. Soviet studies now command a very great interest and are being undertaken at some twenty universities and research institutes mainly in the United States, the United Kingdoin and the German Federal Republic. However, it would seem that the study of the development of the forestry sector has riot received the detailed attention given to other fields. In any case, there have not been any analytical studies published to date elucidating fully the connection between forestry and the forest industries and the integration of both in the economy as a whole. Studies of specific sections have appeared from time to time, but I have no knowledge of any previous study which gives a complete picture of the Soviet forest economy and which could faci- litate the marketing policies of the western world, being undertaken at any university or college.

E-mail: [email protected] Abstract The larvae of four species of Platambus Thomson, 1859 from Japan, P. pictipennis (Sharp, 1873), P. convexus Okada, 2011, P. fimbriatus (Sharp, 1884) and P. sawadai (Kamiya, 1932) are described for the first time including a detailed chaetotaxy analysis of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. A provisional parsimony analysis based on 39 informative larval characteristics of 15 species in seven genera of the subfamily Agabinae was conducted using the program TNT. Larvae of the Platambus species studied stand out from those of other genera of Agabinae by the unique presence of a subquadrate last abdominal segment not protruding posteriorly into siphon and the much shorter length of the primary urogomphal seta UR5 compared to seta UR7 in first instar larva. Key words: Coleoptera, Dytiscidae, Agabinae, Platambus, chaetotaxy, larvae, Palearctic Introduction The dytiscid genus Platambus Thomson, 1859 contains 67 species distributed in the Nearctic, Neotropical, Orien- tal and Palearctic regions (Bian & Ji 2008; Hendrich & Przewoźny 2015; Hájek & Zhang 2019; Nilsson & Hájek 2019).

This article also reveals that some of the medium-sized species of interest, such as those of the genus Rhantus have been included, as have species from other groups, including the raft spider, Dolomedes plantarius (Clerck) and a rare wasp, Chalcis sispes (L.), parasitic on soldierflies (Stratiomyidae), which collectively highlight the conservation importance of some of the very special habitats in which they may be found. Figure 1 Rhantus frontalis (Marsham), brackish pool, Canvey Island, South Essex February 2020 LATISSIMUS 45 2 The prospective book, therefore, covers a good number of medium-sized water beetles (7- 13 mm), from the Piles Beetle Liopterus haemorrhoidalis (Fab.) (6.3-7.9 mm) to the comparatively large Ilybius ater (12.5 -14.5 mm), known by some in Britain as the Mud Dweller.

Cover photograph: Low Weald Pond, Lee Brady Report production: February 2009 Consultation: March 2009 SUMMARY Ponds are an important freshwater habitat and play a key role in maintaining biodiversity at the landscape level. However, they are vulnerable to environmental degradation and there is evidence that, at a national level, pond quality is declining.
