Acylophorus salifi Lott, new species
No full textAcylophorus salifi Lott, new species (Figs 18, 46, 67, 94, 108, 126– 128) Description. Length 6 –7mm. Head black. Pronotum dark brown to black. Scutellum black. Elytra red-brown to black. Abdomen black, iridescent to varying degrees. Sometimes the body is all brown. Legs red. Antennae pale or dark with segment I pale. Maxillary palpi usually all pale. Head much smaller than in A. orientalis (pronotum 2 x wider than head), more or less as long as wide with temples barely suggested (Fig. 18). Antennae inserted right on front margin with no pigmented area in front. No micro-punctures visible at 80 x magnification. Short pubescence behind eyes localised and much sparser than in A. orientalis. Two pairs of interocular setae arising from foveate punctures much closer to eyes than each other and five postocular setae visible from above on each side. No extra seta by hind margin of eye. Underside of head with sparse pubescence, weakly depressed at base (Fig. 108). Gular sutures continued to base of head, converging toward base but well separated throughout their length. Mandibles short with no medial teeth in front of a wide flange (Fig. 46). Maxillary palpi with terminal segment densely pubescent, markedly asymmetric, longer than short, triangular, glabrous penultimate segment (Fig. 67). First segment of antenna as long as next four (Fig. 94). Segments I to V elongate, VIII to XI transverse. Pronotum transverse (1.4x wider than long) with rounded sides and widest in basal half. Shining with no micro-punctures. One pair of dorsal setae. One pair of lateral setae. Marginal setae long. Elytra strongly transverse (1.65x wider than long) with relatively short pubescence arising from fine, asperate punctures. Fringe of bristles on hind margin longer than the hairs on the rest of the elytra. Asperate punctures on abdominal tergites stronger than on elytra, denser toward base. Paramere bilobed, each lobe weakly arched and well separated, pegs confusedly arranged in apical half of each lobe (Figs 126–128). Median lobe longer than paramere, barely expanded at apex which is rounded. There is considerable variation in the form of the aedeagus. The lobes of the paramere can be very slightly curving inward toward apex or slightly diverging. The apex of the median lobe can broadly rounded, sometimes with a central point, or more produced.

ZIMBABWE: Salisbury, GAK Marshall, vii. 1896, 4 (BMNH). Distribution and bionomics. A widespread species ranging from Burkina Faso to Angola, but not yet known from East Africa (Fig. 145). One of the more frequently collected species from the Congo catchment, where it has been found in “humus” in gallery forests as well as “roseaux morts” on a riverbank. Nearly all the specimens from Burkina Faso were collected by dissecting tussocks in well vegetated margins of large reservoirs constructed for irrigation or as waterholes for wildlife in the Nazinga Game Reserve. Discussion. There are variations in both coloration and the form of the aedeagus (Figs 126–128). Most of this variation occurs between specimens taken from localities in the Congo catchment. Outside this area, most specimens are black with reddish elytra, sometimes with black front and side margins. The variations in the aedeagus occur both between different localities and to some extent within series taken from the same locality. Intermediate forms occur between the extremes of each type of variation, but some populations may be referable to distinct taxa once sufficient material from further localities becomes available for study. Etymology. This species is named after Salif Mohammed Ouedraogo of Ouagadougou, driver extraordinaire, who accompanied me on my expeditions in Burkina Faso. The species name is the genitive case of a Latinised version of his name.Published as part of Lott, Derek A., 2010, The species of Acylophorus Nordmann (Coleoptera: Staphylinidae: Staphylininae) in continental sub-Saharan Africa, pp. 1-51 in Zootaxa 2402 on pages 25-26, DOI: 10.5281/zenodo.27590
Limit Theorem for a Modified Leland Hedging Strategy under Constant Transaction Costs rate
No full textWe study the Leland model for hedging portfolios in the presence of a constant proportional transaction costs coefficient. The modified Leland's strategy recently defined by the second author, contrarily to the classical one, ensures the asymptotic replication of a large class of payoff. In this setting, we prove a limit theorem for the deviation between the real portfolio and the payoff. As Pergamenshchikov did in the framework of the usual Leland's strategy, we identify the rate of convergence and the associated limit distribution. This rate turns out to be improved using the modified strategy and non periodic revision dates.Asymptotic hedging ; Leland-Lott strategy ; Transaction costs ; Martingale limit theorem.
Acylophorus makhoreae Lott, new species
No full textAcylophorus makhoreae Lott, new species (Figs 8, 38, 58, 84, 116) Description. Length 7mm. Body colour very variable ranging from pale brown to black. Pronotum yellow to red-brown with a dark, diffuse mark covering the disc and sometimes suffused almost to the edges. Abdomen iridescent when dark. Appendages similarly variable in colour, but the terminal segment of the maxillary palpi is always darker than the penultimate segment. Head of average size (pronotum 1.75x wider than head), more or less as long as wide with rounded temples not very evident (Fig. 8). Pigmented area of head extending well in front of antennal insertion. Micropunctures extending over much of head, but very sparse away from the front of the head and next to the eyes. Dense short pubescence behind eyes. Two pairs of interocular setae arising from foveate punctures much closer to eyes than each other. Only four postocular setae visible from above on each side. Underside of head sparsely pubescent, depressed at base with gular sutures separate, but very proximate toward base. Right mandible with one sharp median tooth; left mandible lacking sharp tooth (Fig. 38). Maxillary palpi with terminal segment densely pubescent, with rounded angle on outer margin, asymmetric and less elongate than A. orientalis, longer than glabrous penultimate segment which is slightly elongate (Fig. 58). First segment of antenna as long as next five. Segments I to IV elongate, VII to XI transverse (Fig. 84). Pronotum only slightly transverse (1.1x wider than long) with rounded sides and widest in basal half. Shining with no micro-punctures. Dorsal, lateral and marginal setae shorter than in A. orientalis. Elytra transverse (1.7x wider than long) with pubescence arising from asperate punctures. Apical fringe of bristles longer than the hairs on the rest of the elytra. Abdominal tergites with evenly spaced, relatively sparse asperate punctures. Paramere bilobed, each lobe fairly flat, at least toward apex, pegs concentrated in dense mass at apex (Fig. 116). Median lobe longer than paramere with truncate apex. Type material.

Clark B.M. 1973 - 450 / PARATYPE Acylophorus makhoreae sp. n. det. DA Lott, 2009 ” (BMNH). Distribution and bionomics. All material seen so far comes from the south-west of Ethiopia (Fig. 142). I have also seen a female specimen collected at “ 8,000 ” feet from the Djem-Djem Forest to the west of Addis Ababa that may belong to this species. Most of the specimens were collected along streams. Comparative notes. Fairly distinct within the A. orientalis species group by virtue of the position of the antennal insertion, the broader, more asymmetric terminal segment of the maxillary palpi and the more transverse medial antennal segments. The form of the aedeagus and the arrangement of medial teeth on the mandibles are also useful characters. Etymology. Makhore was a legendary queen, who founded the kingdom of Jimma in the area where many of the type specimens were collected. The species name is the genitive case of a Latinised version of her name. Discussion. A. makhoreae has been placed in the A. orientalis group, because it lacks dense micropunctures on the head and pronotum. However, the form of the maxillary palpi, the mandibles and the aedeagus and the position of the antennal insertion point all suggest that it may be more closely related to some of the species in the A. densipennis group.Published as part of Lott, Derek A., 2010, The species of Acylophorus Nordmann (Coleoptera: Staphylinidae: Staphylininae) in continental sub-Saharan Africa, pp. 1-51 in Zootaxa 2402 on page 15, DOI: 10.5281/zenodo.27590

No full textAcylophorus tshuapensis Lott, new species (Figs 7, 57, 83, 115) Description. Length 8mm. Head black. Pronotum chestnut brown. Elytra brown. Abdomen dark and iridescent. Legs pale. Antennae pale with segments II to VIII slightly infuscated. The maxillary palpi are uniformly pale. Head somewhat small (pronotum 1.8x wider than head), as long as wide with rounded, not very pronounced temples and antennal insertion close to front margin, but separated by narrow pigmented strip (Fig. 7). Eyes relatively small. Micro-punctures very sparse. Dense short pubescence behind eyes. Two pairs of interocular setae arising from foveate punctures much closer to eyes than each other. A line of five postocular setae plus an additional short seta on hind margin of eye. Maxillary palpi with terminal segment very elongate, densely pubescent, and symmetric, longer than glabrous penultimate segment which is also elongate (Fig. 57). First segment of antenna as long as next three. Segments I to IX elongate, X transverse (Fig. 83). Pronotum only slightly transverse (1.1x wider than long) with rounded sides and widest in basal half, front margins somewhat produced at sides. Shining with no micro-punctures. One pair of dorsal setae. One pair of lateral setae. Marginal setae long. Elytra transverse (1.6x wider than long) with pubescence arising from relatively fine asperate punctures. Apical fringe of thick bristles longer than the hairs on the rest of the elytra. Abdominal tergites with long semi-erect pubescence arising from asperate punctures that are denser at the base of each tergite. Hairs longer than marginal fringe of bristles. Paramere entire with wide central groove at apex, suggesting two parallel lobes that have become fused together (Fig. 115). Median lobe much longer than paramere and strongly expanded at apex. Type material. Holotype 3: “ COLL. MUS. CONGO Tshuapa: Flandria 18 -x- 1946 Rév. P. Hulstaert / R. DET. UU 5694 / Acylophorus sp. n / HOLOTYPE Acylophorus tshuapensis sp. n. 3 det. DA Lott, 2009 ” (IRSNB). Distribution and bionomics. Known only from the holotype taken in the Democratic Republic of Congo (Fig. 142). Comparative notes. Fairly distinct within the A. orientalis species group by virtue of its small eyes, more sinuate front margin to the pronotum and the fused lobes of the paramere. The medial segments of the antennae and the terminal segment of the maxillary palpi are also more elongate than in the other species of the group. Etymology. The specific name is the masculine form of an adjective meaning “from Tshuapa”.Published as part of Lott, Derek A., 2010, The species of Acylophorus Nordmann (Coleoptera: Staphylinidae: Staphylininae) in continental sub-Saharan Africa, pp. 1-51 in Zootaxa 2402 on pages 14-15, DOI: 10.5281/zenodo.27590
The non-commutative standard model
No full textIn this work aspects of the classical Connes-Lott non-commutative standard model are examined. In particular the relationship between the chiral structure of the standard model and the condition of Poincaré Duality is investigated. Then the natural prediction of an additional force in the non-commutative standard model is explained and the consequences calculated. Finally the attempts at grand unification within the non-commutative framework are reviewed and extended
