March 2006 Website: www.stickinsect.org.uk Newsletter 105.2 Editorial Welcome to the March PSG Newsletter. New Printers. Well, here it is - the newly printed Newsletter. We have been very lucky in getting our printing done in the past by the Open University, and then by Paul Brock's school. Not only did this save the PSG lots of money, but it was only possible with the sterling efforts of David Robinson, and more recently Paul Brock. In particular Paul not only kept all our membership details up to date and sorted out all the PSG finances, he also printed, collated, and sent out all the PSG Newsletters and Phasmid Studies - what a star. Anyway, Matthew runs a commercial printers that also prints other notable Newsletters. He has been very helpful with his advice on the different options, and I look forward to working with him from now on. As the Newsletter is now printed on A3 paper (the most cost-effect option), it means it has to be printed in multiples of 4 (eg 20, 24, or 28 pages); this was a bit of a challenge for me. As was the fact that one A3 sheet will be printed in colour, ie which pages do I choose to put in colour? I thought pages 1 and 2, plus the last two pages. So I gave it my best shot, and I hope you enjoy a good read. Articles and Photographs. I am as always much indebted to all contributors. In particular Paul Brock, Chris Pull, and Cameron; whose regular contributions are very welcome. Please keep the contributions coming in especially articles and photos. I had to use a lot of Stick Talk photos again, as I had few sent to me for use in the Newsletter. Stick Talk photos are plentiful, of a high standard, and most are by PSG members. If you want to know more about Stick Talk, see page 6. Phasmid Studies. This will now be available on the PSG website but, unlike the Newsletter, members will not automatically be sent a free, printed copy by post - unless they specifically ask for it. Full details are on page 17, please ensure you read this page. Competition. There is a competition with a difference on page 15. It is based on the weight of a Jungle Nymph, and there will be a weigh-in at the PSG Summer Meeting on 8th July 2006. The winner could end up in the Guinness Book of Records! If you keep Jungle Nymphs (Heteropteryx dilatata) please take part in the competition and help to make it a success. Cockroaches. I get lots of queries from members asking if there is a Cockroach Culture Group. The simple answer was that I did not know. However, like many PSG members, I do keep a selection of these interesting creatures. Well now you can read all about it in the new Cockroach Studies newsletter. Full details of the newly re-formed Cockroach Culture Group, and how to obtain a free, colour copy of the new Cockroach Studies newsletter, are on page 15. PSG AGM & Winter Meeting. Finally, I believe we all had a great time at the PSG AGM and Wnter Meeting. I know I did. As usual, the day was just not long enough; there was so much to do and see and people to meet. I would recommend that all PSG members attend a PSG meeting at least once in their lifetime; apart from the enjoyment you would have, we would all very much like to meet you. Unfortunately, not everyone can attend; therefore, I have done an article on the day, and included pictures of the day's events - see the front cover and page 22 - which hopefully will give you a flavour of that happy day. Also, Cameron has reported on the day's competition, with pictures, see page 19.

Considering that this is a one volume piece of work, the authors seems to have managed this monumental task rather well, getting the whole lot into 700 large pages. One of the most noticeable features of the book is the large number of pictures. Virtually every page L.VUIUI Kill has at least one, if not two, that really do complement the text. Not only are they high in number but of the also they are also high in quality and vary in format from diagrams and line drawings, to colour photographs and images from a scanning electron microscope. There are many exceptional photographs throughout and are either of existing species or are of superbly preserved fossils, particularly in amber. Although there are many that are worthy of comment, one striking one is of the human louse on page 271.

Multiple ecomorphs are present in the stick insect fauna from Papua New Guinea, including the tree lobster, spiny, and long slender forms. While ecomorphs have long been recognized in phasmids, there has yet to be an attempt to objectively define and study the evolution of these ecomorphs.

    Shifting Ranges of Two Tree Weta Species (Hemideina Spp.)

    Journal of Biogeography (J. Biogeogr.) (2014) 41, 524–535 ORIGINAL Shifting ranges of two tree weta species ARTICLE (Hemideina spp.): competitive exclusion and changing climate Mariana Bulgarella*, Steven A. Trewick, Niki A. Minards, Melissa J. Jacobson and Mary Morgan-Richards Ecology Group, IAE, Massey University, ABSTRACT Palmerston North, 4442, New Zealand Aim Species’ responses to climate change are likely to depend on their ability to overcome abiotic constraints as well as on the suite of species with which they interact. Responses to past climate change leave genetic signatures of range expansions and shifts, allowing inferences to be made about species’ distribu- tions in the past, which can improve our ability to predict the future. We tested a hypothesis of ongoing range shifting associated with climate change and involving interactions of two species inferred to exclude each other via competition. Location New Zealand. Methods The distributions of two tree weta species (Hemideina crassidens and H. thoracica) were mapped using locality records. We inferred the likely mod- ern distribution of each species in the absence of congeneric competitors with the software Maxent. Range interaction between the two species on an eleva- tional gradient was quantified by transect sampling. Patterns of genetic diver- sity were investigated using mitochondrial DNA, and hypotheses of range shifts were tested with population genetic metrics. Results The realized ranges of H. thoracica and H. crassidens were narrower than their potential ranges, probably due to competitive interactions. Upper and lower elevational limits on Mount Taranaki over 15 years revealed expan- sion up the mountain for H. thoracica and a matching contraction of the low elevation limits of the range of H.

Resumen. – Un nuevo fásmido del género Oncotophasma de Costa-Rica (Phasmatodea, Diapheromeridae, Diaphero merinae). Una nueva especie de Phasmatodea de Costa Rica, Oncotophasma laetitiae n. sp., es descrita e ilustrada, incluyendo ambos sexos y el huevo. Keywords. – New species, taxonomy, morphology, host plant. _________________ A new phasmid species was collected by the author in 2011 in Costa Rica, in the Heredia Province at the Research Station of Refugio de Vida Silvestre Cerro Dantas, at about 2000 m above sea level. Three females, one male and two female nymphs were found on the same shrub but only one pair was collected. The specimens were found in copula, which confirms them to be conspecific. The author obtained one egg from the female kept alive an extra night. Examination has shown this species to belong in the genus Oncotophasma Rehn, 1904 (Diapheromerinae, Diapheromerini) and detailed comparison with the types of the known species has proven this to be a still undescribed species.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

In the case of this species (by comparison with other Aschiphasmatinae eggs) it would appear that the dorsal surface has been correetly identified as that bearing the micropyle, since it is typical in eggs of this group that the operculum should be lilted ventrally and the micropylar plate should bear a ventral central stripe. The orientation would be confirmed by examination of the internal plate as indicated below. a a d (0) p p 1 d (c) (d) (e) Figure 1.
