Hypoaspis muellerae Halliday 2005
No full textHypoaspis muellerae Halliday, 2005 (Figs 38–45) Hypoaspis muellerae Halliday, 2005: 32. Specimens examined. Five paratypes (ANIC 51-002833 – 51-002837) were examined by the first author from Australian National Insect Collection, Canberra (Australia), and each microslide containing one female labelled as: Hypoaspis muellerae Halliday, South Africa, Plettenberg Bay, 18 August 1994, Roadside picnic area, TK. Qin coll., Clover, cape weed, site 30–13. Halliday (2005) described Hypoaspis muellerae from Plettenberg Bay, South Africa. We have re-examined the paratypes of this species, and now take the opportunity to make some additions to the original description. In the description of this species (Halliday, 2005, Fig. 17) setae st4 are obviously present but that was an error, and in all the specimens we examined setae st4 were absent (Figs 39 & 41). The description did not mention the location of iv3, but they are located on the posterolateral angles of the sternal shield in all the specimens we examined (Fig. 41). This species shows some significant morphological character states typical of Laelaspisella: (1) dorsal shield hypertrichous and with at least 11–13 non-secretory slit-like lyrifissures (Figs 38 & 40); (2) metasternal setae st4 absent (Figs 39 & 41); (3) genitiventral shield large, broad and rounded posteriorly (Fig. 39); (4) iv3 located on posterolateral angles of sternal shield (Fig. 41); (5) internal malae densely fringed and with elongate threads (Fig. 42); (6) lateral margin of epistome smooth and anteriorly mucronated (Fig. 43); (7) palp tarsal claw with two tines (Fig. 44). However, it differs from the original concept of Laelaspisella as described by Marais & Loots (1969), because the dorsal cheliceral seta is present (Fig. 45).Published as part of Joharchi, Omid, Ramroodi, Sara & Halliday, Bruce, 2020, Review of the genus Pogonolaelaps Nemati & Gwiazdowicz (Acari: Laelapidae) with description of a new species from Iran, pp. 465-484 in Zootaxa 4820 (3) on pages 477-481, DOI: 10.11646/zootaxa.4820.3.3, http://zenodo.org/record/439805

Idiosoma elliptical, with wide vertex. Dorsal shield weakly arched, surrounded by narrow marginal shield. Ventral opisthosoma with distinctive ornamentation and chaetotaxy, with 9–14 pairs of long, wide, flattened setae. Epigynial shield of female large, with straight lateral edges, its posterior margin behind level of coxae IV. Sternal region with four pairs of sternal setae, of which st 4 are the longest, 3–4 times as long as st 1 –st 3. Anus surrounded by two pairs of adanal setae (Ad), of which the anterior pair is very short, the posterior pair much longer. The unpaired postanal seta is absent. Peritreme relatively short, hookshaped, reaching the lateral edge of the idiosoma, without a poststigmatal extension. Gnathosoma with short hornlike corniculi. Hypostomal setae simple; h 1, h 3 very long, h 2 and h 4 short. Tarsi I have short claws and a very long terminal seta. The tarsi of legs IV are very long. The pedofossae of legs IV are directed transversely, displaced towards the podosoma.Published as part of Dylewska, M., Błoszyk, J. & Halliday, R.

Interview with M.A.K. Halliday
No full text[About the book]
This volume gathers together 14 interviews with M A K Halliday, the founder of systemic functional linguistics (SFL), recorded over four decades – the most recent of which was conducted in 2011 and published here for the first time. In these engaging conversations with colleagues Halliday explores his own development as a student of language in Britain and China, the evolution of SFL theory around the world, its place in the field of general linguistics and its many sites of application.
The dialogic mode enacted here allows Halliday to touch on many points of personal history and intellectual challenge that have not been addressed in formal publications (in his books or collected papers), including answers to the many thought-provoking questions his colleagues had waited sometimes years to ask. Accordingly each chapter offers a fresh illuminating window on the innovative thinking and assured convictions of this towering figure in linguistics
