Martensopsalis Giribet & Baker & Brouste 2021, gen. nov.
No full textMartensopsalis Giribet & Baker gen. nov. (Figs 1, 3–6) ZooBank registration: urn:lsid:zoobank.org:act: 04C4AC0D-DE0C-46F0-AB6A-F5D2B3D24514 Type species. Martensopsalis dogny spec. nov. Diagnosis. Martensopsalis can be distinguished from all other genera of Neopilionidae by the presence of a pointed basal apophysis on the ventral side of the palpal femur (Figs 3, 4C), although being more conspicuous in some individuals than others; palpal patella with a distal-prolateral apophysis (Figs 3, 4C), also with different degrees of development; palpal patella and tibia of similar size; palpal tarsus longer than other articles; a dense set of thick setae on all palpal articles; palpal claw well developed and smooth. Penis with long sclerotized straight shaft with a short glans, and the stylus being a coiled tube; without bristles, spines or setae. Description. Prosoma weakly sclerotized, smooth; carapace with the metapeltidium 2 well demarcated; opisthosoma unornamented; dorsum color of earth tones or green, with a transverse reflective pale/orange band on first opisthosomal tergite (Figs 3, 4A–B, 6A); ozophores large, raised and visible from above, located immediately behind fixed spine of coxa I. Ocularium large, smooth, positioned behind anterior margin of carapace at a distance equal to length of ocularium (Figs 4A–B, 6A, C). Chelicerae (Figs 4B, D) of normal size, without evident sexual dimorphism; second article setose, except for fixed finger; movable finger without setae. Palp (Fig. 4C) covered with stiff thick setae, giving it a spiny appearance; without plumose setae; femur with a distinct basal-proventral apophysis (Figs 3, 4C); patella with a distinct prodistal apophysis (Fig. 3); patella and tibia of similar size; tarsus longer than femur, slightly bent; tarsal claw without ventral teeth. Coxae of legs I–III with dorsal spines; other leg articles without denticles or spines. Legs long and slender, femur I longer than carapace; pseudoarticulations of tarsi with paired ventral spines; leg II with two pseudoarticulations on femur and eight on tibia; leg IV with two or four pseudosegments on tibia only, not always the same in the corresponding right and left legs. Penis (Figs 4E, 5) simple, with a straight shaft, without spines, groups of bristles or sensory setae; shaft folding towards the tip from which the short glans and the coiled stylus tube protrude. Etymology. Named for our dear colleague Jochen Martens for his contributions and enormous influence on Opiliones systematics. The second part of the generic name is the classical Greek noun “psalis” (= scissors) which has been previously used in the names of other genera of Neopilionidae such as Megalopsalis, Forsteropsalis and Pantopsalis. The gender is feminine. Distribution. Widespread in the southern half of New Caledonia’s Grande Terre. Comments. Martensopsalis is so far the only genus of Neopilionidae in New Caledonia, known only from four specimens collected during our 2018 expedition and from additional records posted on iNaturalist. The simple straight penis without setae or spines and with a short glans with a long stylus distinguishes Martensopsalis from most other neopilionids, including all other Australasian species. The penis of Neopilio Lawrence, 1931 is similar in lacking supination and setae and in having the stylus developed as a tightly coiled tube, but the shaft widens basally (Hunt & Cokendolpher 1991; Lotz 2011).Published as part of Giribet, Gonzalo, Baker, Caitlin M. & Brouste, Damien, 2021, Martensopsalis, a new genus of Neopilionidae from New Caledonia (Opiliones Eupnoi), pp. 98-107 in Zootaxa 4984 (1) on pages 100-101, DOI: 10.11646/zootaxa.4984.1.9, http://zenodo.org/record/492887

NEW CALEDONIA: Province Sud: Holotype male (MNHN; ex. MCZ IZ- 1524013; 1 leg used for DNA extraction; DNA kept in MCZ cryogenic collection; GenBank accessions MW 849412 [18S rRNA], MW 843230 [28S rRNA], MW 837103 [COI]) from Sarrameìa, Plateau de Dogny, 21°37’1.06”S, 165°53’2.15”E, 914 m elevation, C.M. Baker & G. Giribet leg. 15.11.2018, collected by sifting leaf litter. Paratypes: 1 female (MCZ IZ-152402; 1 leg used for DNA extraction; DNA kept in MCZ cryogenic collection; GenBank accessions MW 849413 [18S rRNA], MW 843231 [28S rRNA], MW 837104 [COI]), 1 unsexed specimen (MCZ IZ-151592; 1 leg used for DNA extraction; DNA kept in MCZ cryogenic collection; GenBank accessions MW 849411 [18S rRNA], MW 843229 [28S rRNA], MW 837102 [COI]), with same collecting data as for holotype. Etymology. The specific epithet, a noun in apposition, refers to the type locality, an emblematic mountain of New Caledonia that served as a place for exchange between the tribes from the east and the west of Grande Terre. Diagnosis. As for genus. 3. This specimen was accessioned in the MCZ before becoming the holotype of a new species, which, for permit requirements, had to be deposited in the MNHN. Because the species was originally catalogued in MCZbase, its collecting data and images were available online before a new taxon was described, and because one leg and its DNA remain stored in the MCZ cryo - genic collection, we kept this record with the MCZ accession number. Description. Male (holotype; Figs 4–5): As for genus. Body length 1.38, maximum width 1.14; carapace length 0.60, width 1.14; ocularium width 0.42, length 0.26, located 0.28 from anterior margin of carapace. Dorsum color a combination of earth colors (brown to orange-color) with a reflective band on first opisthosomal tergite when preserved in ethanol (Figs 4A–B). Cheliceral articles 0.52, 0.95 and 0.31 long from basal to distal. Palpal trochanter 0.27 long, femur 1.00, patella 0.65, tibia 0.55, tarsus 1.16 (Fig. 4C). Penis shaft 0.69, glans short, 0.15 long and twisted clockwise (Figs 4E, 5). Female (paratype MCZ IZ-152402; Fig. 6): body length 1.66, maximum width 1.12, height without ocularium 1.22; carapace length 0.64, width 1.08; ocularium width 0.44, length 0.36, height 0.18, located 0.24 from anterior margin of carapace. Color as in male holotype. Ovipositor not studied. Distribution. Only known from its type locality, the Plateau de Dogny, at an elevation above 900 m. Comments. Martensopsalis dogny spec. nov. is the only species in this new genus that we were able to study in detail. Another specimen from high elevations at Mé Maoya (Province Nord; Fig. 1C) was included in a phylogenetic analysis (see Fig. 7) which showed that it is not conspecific with the species described here. Genetic and morphological studies of additional specimens from the localities reported in Table 1 will probably reveal the presence of additional species of Martensopsalis gen. nov.Published as part of Giribet, Gonzalo, Baker, Caitlin M. & Brouste, Damien, 2021, Martensopsalis, a new genus of Neopilionidae from New Caledonia (Opiliones Eupnoi), pp. 98-107 in Zootaxa 4984 (1) on pages 102-103, DOI: 10.11646/zootaxa.4984.1.9, http://zenodo.org/record/492887

Parameter estimation for the discretely observed fractional Ornstein-Uhlenbeck process and the Yuima R package
No full textThis paper proposes consistent and asymptotically Gaussian estimators for the parameters λ, σ and H of the discretely observed fractional Ornstein-Uhlenbeck process solution of the stochastic differential equation dYt = −λYtdt+σdWtH, where (WtH,t ≥ 0) is the fractional Brownian motion.
For the estimation of the drift λ, the results are obtained only in the case when 1 < H < 3. This paper also provides ready-to-use software for the R statistical environment based on the YUIMA package
