New species of Dolichopoda Bolívar, 1880 (Orthoptera, Rhaphidophoridae) from the Aegean Islands of Andros, Paros and Kinaros (Greece)
Get PDFIn this paper two new species of Dolichopoda Bolívar, 1880 from the Cyclades islands of Andros and Paros and one from the Dodecanissos island of Kinaros, are described, increasing the total number of Greek species to 32. The new species from Paros (D. kikladica Di Russo & Rampini, n. sp.) and Kinaros (D. margiolis Di Russo & Rampini, n. sp.) show strong similarities with D. naxia Boudou-Saltet, 1972 from Naxos forming an homogenous group limited to the central Aegean islands. On the other hand the species D. christos-nifoni Di Russo & Rampini, n. sp. from Andros shows a combination of morphological characters that partly resemble characters found in Evvian Dolichopoda, and partly in species from the Cyclades. Relationships among these three new taxa and the other adjacent Dolichopoda species are discussed on the basis of the paleogeological and paleoclimatic events that shaped the present geography of the Aegean area
Dolichopoda apollinea Di Russo and Rampini, sp. nov.
No full textDolichopoda apollinea Di Russo and Rampini sp. nov. (Figure 8) Type material Holotype J: Calabria, Pollino Massif, Cassano allo Ionio, Sant ̍ Angelo cave complex, 260 m asl., 14 December 2021, Di Russo and Rampini leg. (MZUR). Other material examined Same locality, date and collector as the holotype: 4J, 3♀, 1 nymph. Calabria, Pollino Massif, Cerchiara Calabra, Serra del Gufo cave, 15.06.2019 F. Larocca leg. 2 nymphs; Pollino Massif, S. Lorenzo Bellizzi, Conoide cave, 04.07.2019 F. Larocca leg. 1J; Pollino Massif, Francavilla Marittima, Caprio cave, 20.10.2019 F. Larocca leg. 1♀, 2 nymphs. Type locality The Sant̍ Angelo cave complex is a group of 16 more or less developed caves located at the base of the karst hill named ′il muraglione̍. Two of these, situated at 260 m asl, are more than 1000 m long (Larocca 2003). Etymology The name of the new taxon refers to the ancient appellation of the Pollino Massif as Apollo Mountain. Diagnosis The new taxon is different from the other Calabrian species in the smaller size of the males, the more squared lobes of the tenth tergum that are strongly haired, and the median process of the epiphallus characterised by a prominent carina extending from the base for more than half its length. On the contrary, the females appear quite similar to D. palpata and D. calabra in the shape of the subgenital plate and the denticulation of the inner valvae of the ovipositor. Description Male. Relatively small in size; not uniform in body colour, thorax and abdomen brownish dorsally while paler ventrally. Legs long, uniformly yellowish, with the posterior edge darker. Femora unarmed. Fore tibia armed with 5–6 spines on sides of the lower edge, 3/5 spines on the upper edge. Mid tibia with 5/7 short spines on both sides of the upper edge and 3/4 spines on the lower edge. The hind tibia is longer, with 19/21 spines of varying length on both sides of the upper edge and 3 homogeneous spines on the lower external edge. Tenth tergum with two almost squared lateral lobes, strongly haired (Figure 9 (a)). The lobes are separated by a large median depression holding two pronounced conical tubercles. The subgenital plate is globular and deeply incised in the middle; lateral lobes are triangular with two prominent cylindrical styli (Figures 9 (b,c)). The median process of the epiphallus is almost slender, with a triangular basis. In the middle, a prominent carina occurs from the basis to almost the second half of the total length. In lateral view it is uniformly curved. Narrow basal process with the anterior lobes more developed than the posterior ones (Figures 9 (d,e)). Plica dorsalis membrane semicircular in shape. Length (mm): body 15.00; pronotum 4.00; fore femur 15.00; mid femur 15.00; hind femur 24.00; fore tibia 17.00; mid tibia 18.00; hind tibia 30.00; hind tarsus 11.00; 1st article of hind tarsus 6.00. Female. Relatively larger than male (16–24 mm). Sternites VII, VIII and IX are well developed, showing a prominent posterior edge. Subgenital plate sclerotised, globular and semicircular (Figure 9 (f)). Ovipositor uniformly curved (12 mm) with the apex of the external valvae strongly acuminated and curved upward. The inferior valvae, with the base almost round, have 17–20 denticles (Figure 9 (g)).Published as part of Di Russo, Claudio, Allegrucci, Giuliana & Rampini, Mauro, 2023, Molecular and morphological analyses disclose the existence of three species of Dolichopoda (Orthoptera: Rhaphidophoridae) in the Calabria region (Italy), pp. 372-394 in Journal of Natural History 57 (5 - 8) on pages 382-387, DOI: 10.1080/00222933.2023.2186277, http://zenodo.org/record/779973
Dolichopoda muceddai Rampini & Di Russo, nuova specie di una famiglia di Ortotteri nuova per la Sardegna (Orthoptera Rhaphidophoridae)
No full textNew species of the genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) from Western and Southern Anatolian caves, Turkey
No full textIn this paper four new species of Troglophilus Krauss, 1879 cave crickets from Southern and Western Anatolia are described (T. alanyaensis, T. fethiyensis, T. ozeli and T. ferzenensis). Considering the other five species already documented from the area, there is now a total of 9 recorded species of Troglophilus that currently inhabit the caves and epigean habitats of Turkey. The occurrence of two new species in the western Aegean region of the Anatolia (Troglophilus fethiyensis sp. nov. and T. ozeli sp. nov. from Mugla and Havran provinces respectively) allowed us to improve considerevely the knowledgements on their geographic ditribution in Turkey, until now limited to the Southern Anatolia and a to a little enclave of Pontic region. The new species are all morphologically homogeneous, showing a clear affinity with the other Anatolian species T. adamovici Us, 1974; T. gajaci Us, 1974; T. escalerai Bolivar, 1899 and T. bicakcii Rampini & Di Russo, 2003 from Southern Taurus caves. The best character that permits to distinguish these groups is the ovipositor shape. Of particular interest is the finding of the new species T. ferzenensis sp. nov. in the Ferzene cave. This species, synoptic with T. adamovici, although morphologically similar to T. escalerai, differs from all the known Turkish species in the different spinulation of the legs, resulting close to the Aegean species T. spinulosus Chopard, 1921 from Crete and T. marinae Rampini & Di Russo, 2003 from Santorini

Time Course of Reactive Brain Activities during a Stroop Color-Word Task: Evidence of Specific Facilitation and Interference Effects
No full text: The Stroop test represents a widely used task in basic and clinical research for approaching the cognitive system functioning in humans. However, a clear overview of the neurophysiological signatures associated with the different sub-domains of this task remains controversial. In the present study, we leveraged the EEG technique to explore the modulation of specific post-stimulus ERPs components during the Stroop test. Critically, to better disentangle the contribution of facilitation (i.e., faster color identification times for color-congruent Stroop words) and interference (i.e., longer color identification times for color-incongruent Stroop words) processes prompted by the Stroop test, we delivered congruent and incongruent trials in two separate experimental blocks, each including the respective neutral condition. Thanks to this methodological manipulation, we were able to clearly dissociate the two sub-processes. Electrophysiological results suggest specific markers of brain activity for the facilitation and the interference effects. Indeed, distinctive Stroop-related ERPs (i.e., the P3, the N450, and the LPC) were differently modulated in the two sub-processes. Collectively, we provide evidence of selected brain activities involved in the reactive stage of processing associated with the Stroop effect
Turning black-holes and D-branes inside out their photon-spheres
No full textVery much as extremal Reissner-Nordst\"om BHs, D3-branes and their
intersecting bound-states in lower dimensions enjoy a remarkable symmetry under
conformal inversions that exchange the horizon with infinity and keep the
photon-sphere fixed. We explore the implications of this symmetry for the
dynamics of massless and massive BPS particles. In particular we find a
remarkable identity between the scattering angle of a probe impinging from
infinity and the in-spiraling angle of a probe with the very same energy and
angular momentum falling into the horizon from inside the photon-sphere. We
argue for the identity of the radial actions and Shapiro time-delays for the
two processes, when a cutoff regulator or an AdS ambient is adopted. We spell
out the detailed conditions for the inversion symmetry to hold in the case of
large BPS BHs in four dimensions. We address conformal inversions for other BHs
and Dp-branes with photon-spheres in various dimensions with flat or AdS
asymptotics. We briefly discuss the fate of the symmetry at the quantum level
as well as for non spherically symmetric BHs and branes and sketch potential
implications for the holographic correspondence.Comment: 26 pages, 6 figures Corrected some misprints, improved discussion on
BHs in Ad
