Cochylimorpha declivana (Kennel, 1901), C. halophilana clavana (Constant, 1888), and C. meridiolana (Ragonot, 1894) are newly re- corded for China. The previously unknown females of C. conankinensis (Ge, 1992), C. maleropa (Meyrick, 1937), and C. razowskiana Kuznetzov, 2005 are described for the first time.

We conducted a multiple-gene phylogenetic analysis of 70 species representing 24 23 genera of Cochylina and eight species representing eight genera of Euliina, and a maximum 24 likelihood analysis based on 293 barcodes representing over 220 species of Cochylina. The 25 results confirm the hypothesis that Cochylina is a monophyletic group embedded within a 26 paraphyletic Euliina. We recognize and define six major monophyletic lineages within 27 Cochylina: a Phtheochroa Group, a Henricus Group, an Aethes Group, a Saphenista Group, a 28 Phalonidia Group, and a Cochylis Group.

Introduction In the winter 2001/2002 the first author studied the Tortricidae collected by Mr. J. Wolschrijn (Twello, Netherlands). J. Wolschrijn has collected moths and butterflies in several European countries. Among the specimens collected in Spain there was one Cochylini, which obviously would belong to an undescribed species. Both the imago and the genitalia are very different from all known species. In 2002 Mr. Wolschrijn collected two more males at the same locality. These two specimens are mentioned here as paratypes.

    Status, Trends and Red Listing – Terrestrial and Fresh Water Insects Sub Group Report – August 2014 1 Appendix 9: Insects Sub-group Report HONG KONG TERRESTRIAL AND FRESHWATER INSECTS STATUS, TRENDS, RED LISTING & RECOMMENDATIONS AUGUST 2014 EXECUTIVE SUMMARY Hong Kong insect biodiversity is at present poorly known, despite the fact that this is the most diverse group of multicellular organisms on the planet. Our knowledge of the status of the local insect fauna is limited to a few insect taxonomic groups (butterflies & moths, dragonflies & damselflies, mayflies, caddisflies, ants, partially beetles, partially aculeate wasp taxa)and in consequence only a few insect taxa have been assessed locally. Knowledge of population trends is minimal. However, over 2400 species of moth, 240 butterflies, 115 dragonflies & damselflies, 180 ants, 70 mosquitoes, 40 termites, and over 150 aculeate Wasps have been recorded locally, as well as hundreds of beetles and smaller numbers of mayflies, caddisflies and stick insects. Some of these insects are endemic to Hong Kong and many species either entirely new to science or to the territory are discovered every year. An assessment conducted by the authors on a fraction of these Hong Kong species has revealed that 29 out of 46 moths , eight out of 10 aculeate wasps and three out of 104 dragonflies assessed qualified for threatened status (Critically Endangered, Endangered and Vulnerable) as defined by IUCN. The ecology of these insects is diverse and understanding this is important to conserving the biota as a whole. A particular need is to study those that perform important known ecological services such as pollination, seed dispersal, nutrient recycling and soil turnover, and to gain a better understanding of their functional role within food webs.

Cochylimorpha arenosana n. sp. from sand dunes of Northern Mongolia is described. Three species, Falseunca­ ria lechriotoma Razowski, 1970,Acleris idonea Razowski, 1972 and Eucosma argentifera Razowski, 1972-all described from Mongolia- are reported as new for Russia. From the total of 145 species 138 can be placed into three main zoogeographical complexes: Holarctic/Palaearctic about 83 %, Mediter­ ranean-Central-Asiatic about 10% and endemic for the mountains of Central­ Asia about 7%. The Holarctic complex can be divided into four chorological groups: Holarctic (22 spp.), Transpalaearctic (65 spp.), Western Palaearctic (12 spp.) and Eastern Palaearctic (13 spp.). Subalpine meadows and grazed steppes of Mongun-Taiga and the Tannu-Ola Mnts. are inhabited by some endemics of the Central-Asian mountains (11 spp.). Vladimir I.

Needless to say, there has been a huge amount of change in the Museum during these past four decades, so a few reminiscences may be in order.
