Pamexis hantam Mansell & Ball, sp. nov.
No full textPamexis hantam Mansell & Ball, sp. nov. Figs 1, 3–5, 9–22, 25, 26, 27 Etymology. Hantam, a noun in apposition, referring to the area in which the new species occurs. The name “ Hantam ” is derived from the Khoisan word!Han=ami, also previously written as ‘heyntams,’ which means “where the red bulbs grow” (TANAP 2016). This refers to a Pelargonium plant with edible roots [probably P. bifolium (Burm.f.) Willd (Germishuizen et al. 2006)]. Description. (Based on holotype male, 12 male, 13 female paratypes) Habitus (Fig. 1). Smallish, robust, broad-winged antlions. Wings pale whitish yellow, with tessellated dark brown markings in forewings and prominent dark brown spots or bands in hind wings, but wing markings in both wings highly variable (Figs 9–10). Head, thorax and abdomen black with yellow markings on thorax. Male ectoprocts short, black, forcipate. Head: black, slightly narrower than prothorax, vertex raised, bi-lobed with long curved black setae dorsally; antennae short, black, strongly clavate, shorter than head width, toruli slightly less than scape-width apart, torular membrane yellow, scape black with long curved setae anteriorly, flagellomeres short, uniformly black, covered with short black setae; eyes characteristically small, less than hemispherical, ocular setae absent but with long curved intermingled black and white setae antero-dorsally, short white setae ventrally and posteriorly; genae shiny black, mandibular articulations yellow, clypeus narrowly black at base, yellow distally, labrum yellowish with two black spots laterally; maxillary and labial palps short, black, terminal labial palpomere spindle-shaped with blunt apex, palpimacula round. Thorax: prothorax almost triangular in dorsal view, with broad black central area and pale spot centrally, lateral margins broadly yellow with two black spots posteriorly, posterior margin black, long black curved setae present along anterior, lateral and posterior margins. Mesoprescutum black with yellow V-shaped mark along posterior margin; mesoscutum black with two large yellow patches anteriorly on either side of midline, two yellow triangular marks at posterior margin and a small yellow spot laterally above each wing base; long black curved setae cover mesonotum, with pale fringe of setae along posterior margin; mesoscutellum black with long white setae along posterior margin. Metaprescutum black, shiny; metascutum black, densely covered with microtrichia, two pale yellow velvety patches present on either side of midline; metascutellum shiny black with row of long white setae along posterior margin. Pleurites and sternites black, covered in long white setae, coxal articular membranes yellow. Wings: short, broad, forewings longer than hind wings, apices rounded, hind margins smooth, membrane pale yellowish-white (greenish in living specimens, fading to pale yellow when preserved); veins pale yellowish-white with variable dark brown markings extending onto membrane (Figs 1, 9, 10) bearing very sparse long white and black setae, hypostigmatic cells long. Forewings: with brown tessellations over most cross-veins, extending onto adjacent membrane; C with short dense black setae, some costal cells biaereolate proximally, pterostigma not discernible, Sc slightly incrassate medially with short setae along distal third, R with row of short curved black setae, slightly longer proximally; Rs arising before Cua fork, 3–7 presectoral crossveins before Rs; Mp2 (oblique vein) arising beyond Cua fork; Cup narrow not fused with A1, A2 and A3 slightly incrassate. Hind wings: pale basally with large spots sometimes coalescing into bands in distal two thirds; origin of Rs proximal to fork of Mp fork; 1 presectoral crossvein, Mp incrassate before fork; incrassate Cua arches forward at junction with posterior branch of Mp, forming the typical palparine recurrent vein; 1A incrassate. Legs: long, black; hind legs extending to abdominal segment 4; tibiae longer than tarsi in all legs, tibial spurs robust, curved, extending to middle of T2; T1 – T4 short, T5 long, approximately equal to combined length of T1– T4; pretarsal claws longer than T1, black, slightly curved. Abdomen: stout, slightly shorter than hind wings, completely black in male (Fig. 25), covered with short black setae, in female usually black with yellow distal margins (Fig. 26). Males with tergite 9 divided (Figs 11–12), sternite IX (Fig. 13) with acute but smooth apex. Ectoprocts (Figs 11–13) curved, cylindrical, with slender spines distally, long slender setae proximally, two stout spines basally; gonarcus and parameres (Figs 14–16) fused into a rigid cone-shaped structure, parameres slerotized, shiny black with medial tuft of sensory setae (Fig. 14), gonarcal bulla (Figs 14–16) translucent; hypandrium internum (Figs 17–19) lightly sclerotized, keel-shaped. Females (Fig. 20) with rounded ectoprocts bearing stout fossorial spines; lateral gonapohyses rounded with stout fossorial spines; anterior gonapophyses rounded with long slender setae; pregenitalae (Fig. 22) triangular, sclerotized; spermathecae (Fig. 21) slender, tapering distally. The small sclerotized triangular pregenitale of the female, which is situated in membranous folds between the anterior gonapophyses serves to accommodate and guide the equally inconspicuous keel-shaped hypandrium internum of the male to the spermatheca during sperm transfer. Larvae: unknown. Distribution. Northern Cape Province, South Africa. Systematic position. Pamexis hantam is morphologically similar to P. namaqua (Fig. 2) and they are clearly adelphotaxa. Mansell (1992) stated that P. namaqua was most closely related to P. contaminatus Hagen, but this relationship has now been superseded by discovery of P. hantam, which is clearly closer to P. namaqua than to P. contaminatus. Pamexis hantam is distinguished from P. namaqua by its larger size and wing length and by the markings on the thorax and black abdomen (Figs 25, 26). The wings of P. hantam are longer and less rounded than those of P. namaqua, and also lack the diffuse brown suffusion manifest in P. namaqua (Fig. 2). The males are easily separated by the black ectoprocts of P. hantam compared to the yellow ectoprocts of P. namaqua (Fig. 23) and the extensive yellow markings on the abdomen of the latter (Figs 23, 24). There appears to be no overlap in the currently known distributions of the two taxa and the adults also have disparate phenologies. Habitat and behaviour. This species occurs over a recorded range of about 25 km from the summit of the Hantam Mountain (Hantamberg) (over 1500 m) southwards to Keiskie Pass and beyond (at 1220 m). The vegetation type on the Hantam Mountain is Hantam Plateau Dolerite Renosterveld (FRd2), while the vegetation type near Keiskie Pass is Roggeveld Shale Renosterveld (FRs3) (Mucina & Rutherford 2006). Both are in the Fynbos Biome. This Pamexis species occurs at the highest altitude (1200–1500 m) of the genus, where the frost incidence is 10–40 days per year. Summers are very hot, with a mean daily maximum temperature of 31.1° for February (Mucina & Rutherford 2006). The unifying feature of all the known localities is the presence of white and black crustose lichens on the rocky landscape with low shrubland and rich herblands containing an abundance of geophytes (Mucina & Rutherford 2006). When settled on the crustose lichens on rocks, these alert insects are exceptionally difficult to detect. The thallus of the lichens is a light whitish/green colour, with the discs of the cup-shaped, lecideine apothecia, being black. These colours are consequently very similar to those of P. hantam, with the rounded dark coloration of the fruiting bodies (apothecia) also being very similar in size and shape to many of the ovoid black markings on the fore- and hind-wings (Figs 3–5). The crypsis/camouflage is enhanced by the extensive pale setae on the head and thorax, which minimize an edge shadow from the visible portion of the body when resting on the lichen covered rocks during the day (see Fig. 4). When disturbed, these rapid-flying diurnal antlions take to the air and are carried by the prevailing winds, settling up to 70 meters away. They usually settle on rocks or the ground. They occasionally also settle on vegetation. Many of the low shrubs in the area of occurrence have grey/green leaves, including Eriocephalus sp. (‘kapokbossie’) and the ‘renosterbos’ (Elytropappus rhinocerotis), again enhancing camouflage. In flight they strongly resemble the local and very widespread butterfly Belenois aurota aurota, the brown-veined white (family Pieridae). The long flight episodes possibly lessen the chance of asilid attack. The rapid transition from a settled and camouflaged insect on a rock to a white flash-pattern on flight is probably an effective anti-predation ‘startling’ attribute. No oviposition sites nor early stages of any of the taxa in this genus are currently known. Material examined.

Abdomen dark blueish-black with pale yellow marks as depicted in Fig. 27; sternite 8 bearing distinct sclerotized fossoria (digging appendages).</p> <p> <b>Biology.</b> Larvae inhabit loose dune sand near vegetation. They have been excavated by sieving, usually several centimetres below the surface. It is possible that they either actively hunt on the surface at night or are crepuscular ambush predators just below the surface, with the red dorsum of the head and prothorax blending with that of the surrounding red Kalahari sand. Their black coloration provides a stark contrast to larvae of <i>Golafrus oneili</i> (Péringuey) and <i>Annulares annulatus</i> (Stitz), which occur in the same habitat but are predominantly white (Mansell 1999, Figs 3, 4, 5). This leads to the conclusion that <i>C. kalaharicus</i> larvae are largely crepuscular and nocturnal, whereas the latter two species spend more time near the surface during daylight, with their white coloration being an adaptation to radiate heat thereby enabling them to tolerate the high surface temperatures more effectively (Mansell 1999). The dark coloration of <i>C. kalaharicus</i> probably is an adaptation to heat retention by surfacehunting nocturnal predators. Adult flight period October to early January.</p> <p> <b>Distribution</b> (Fig. 92). <i>Crambomorphus kalaharicus</i> is endemic to the Kalahari ecosystem of the Northern Cape Province of South Africa, Botswana and Namibia. It is centred and protected within the Kgalagadi Transfrontier Park of South Africa and Botswana.</p> <p> <b>Type material examined.</b> SOUTH AFRICA, <i>Northern Cape Province:</i> Holotype ♂.

MEASURING INFRASTRUCTURE PROJECTS SUSTAINABLE DEVELOPMENT GOALS IMPACT (MISI)
No full textThe research captured in this thesis has led to the development of a range of models, tools and processes for government and industry that provide a forwardlooking approach to the measurement of impact on infrastructure projects. This approach enables measurement of United Nations’ Sustainable Development Goals (UN SDG) at the project level to ensure investments are made equitably across economic, environment and social objectives. Application of the results from this research are already being actively used by the Environment Agency to manage impact assessment across its £5.2Bn portfolio of projects and by the Thames Tideway Project (£4.9Bn).
Background. Achievement of the United Nations’ Sustainable Development Goals (SDGs) by the year 2030 is of paramount importance and the construction industry has a major role in achieving a measurable impact against the SDG targets. However, linking of ‘local’ infrastructure project success to ‘global’ SDG targets is problematic because the targets were designed at the national level and not at the project or programme level (Mansell, et al., 2020a). Furthermore, while the so called ‘triple bottom line’ (i.e. economy, environment and society) approach to understanding sustainability remains important, there is a need to understand how this can be related to the full project lifecycle as well as a need for improved project governance. This is consistent with the findings of a key UN investigation’s Fourth Report (Global Task Force, 2020) which calls for localization of SDGs as well as the need for cooperative governance to establish shared priorities.
Research description. The research was based on two main stages. The first stage, informed by a systematic literature review, comprised a mixed method that involved a survey of 325 engineers to derive quantitative data (Mansell et al., 2020b) along with interviews with 40 CEOs and corporate Heads of Sustainability to capture qualitative data (Mansell et al., 2020c). The second stage involved the development of a prototype that was tested through two further exploratory investigations at two levels: (1) Test 1: is there a Golden Thread from global SDGs, through the organisational level, down to project level SDG impact measurement?; (2) Test 2: does the prototype model, the Impact Value Chain, have practical coherence when PhD: Measuring Infrastructure Projects’ SDG Impact (MISI) v assessed in a brief case study of a Water Utility Company (Anglian Water) (Mansell et al., 2020d). Subsequently, and not part of this thesis, the research led to a collaborative partnership to test the prototype model and its approach across the Environment Agency’s full portfolio of projects and also, the megaproject of the Thames Tideway Tunnel.
Findings. The survey of 325 engineers (Mansell et al., 2020b) indicated four primary shortfalls for measuring SDGs on infrastructure projects, namely leadership, tools and methods, engineers’ business skills in measuring SDG impact, and how project success is too narrowly defined as outputs (such as time, cost and scope) and not outcomes (longer-term local impacts and stakeholder value). Moreover, the interviews with 40 senior executives (Mansell et al., 2020c) from the UK identified that SDG measurement practices are currently ‘more talk less walk’ and indicated a number of contextual and mechanistic opportunities to increase the outcome success.
Therefore, using empirical evidence the researcher identified a ‘golden thread’ between best practice sustainability-reporting frameworks at the ‘local’ project level and those at the organisational and supra-national-levels (Mansell et al., 2020a). In doing so, the research identified that there is sufficient linkage to embed SDG impact targets into the design stage of an infrastructure project. Furthermore, the innovative process model, called the ‘Infrastructure SDG Impact-Value Chain’ (IVC) to link project delivery with strategic SDG impacts, builds on the concept of creating shared value and creates a practical mechanism to turn theory into meaningful impact in project selection and delivery. The utility of the IVC process model was initially investigated as part of the case study investigation of Anglian Water (Mansell et al., 2020d) and its application has been further demonstrated in the MISI Project (not included in this thesis).
Research Impact. The research produced twelve peer-reviewed papers including being published in seven internationally recognised academic journals, such as: Sustainability (2 articles), Administrative Sciences, and the Proceedings of the Institution of Civil Engineers–Engineering Sustainability. The MISI research outputs have been taken forward by the government and industry partners, specifically the Environment Agency and Thames Tideway Project, working together to establish this new approach for measuring sustainability on infrastructure projects

Age of noise [Thinking Allowed with Laurie Taylor, William Haydock, James Mansell, and Marie Thompson, BBC Radio 4]
No full texthe 'age of noise': How a preoccupation with unwanted sounds came to characterise modernity. The 20th century saw the expansion of cities and technological change. The sounds of motor cars, vacuum cleaners and gramophones filled the air, leading social commentators to forecast the end of civilisation and a breakdown in mental health. Did noise provide people with a way of talking about their social anxieties? Does it still serve this function today? Laurie Taylor talks to James Mansell, Assistant Professor of Cultural Studies at the University of Nottingham and Marie Thompson, Lecturer in the School of Film and Media at the University of Lincoln.</p
