Une description amendée pour <i>Rosularia haussknechtii</i> (Boiss. & Reuter) A.Berger (Crassulaceae) du sud-est de l’Anatolie
No full textRosularia haussknechtii s.str. est un taxon énigmatique endémique du sud-est de l’Anatolie. La description de cette espèce n’ayant été établie que sur des spécimens d’herbiers et à partir d’échantillons secs et vivants de R. pseudohaussknechtii Niederle de manière incorrecte, elle comporte malheureusement de nombreuses lacunes et erreurs. Avec cette étude, la seule localité type connue de R. haussknechtii s.str. a été recollectée pour la première fois depuis 1865, et une nouvelle localité distincte a également été reconnue. Sur la base des spécimens vivants de ces différentes populations, la description de l’espèce a été amendée. Compte tenu de ces nouvelles informations, l’habitat et les caractéristiques écologiques de R. haussknechtii s.str. ont été précisés et une carte de répartition en Turquie a été établie.Rosularia haussknechtii s.str. is an enigmatic endemic taxon only spread in Southeastern Anatolia. Since the description of this species has been made only on herbarium specimens and from herbarium and live samples of R. pseudohaussknechtii Niederle incorrectly, unfortunately, it contains many deficiencies and mistakes. With this study, the only known type locality of R. haussknechtii s.str. was collected for the first time since 1865, and a new different locality was also found. Based on the live specimens from these different populations, the description of the species was emended. Considering these new data., habitat and ecological characteristics of R. haussknechtii s.str. were determined and distribution map in Türkiye was given.</p
Révision de l’énigmatique serpent <i>Plesiotortrix edwardsi</i> Rochebrune, 1884 des Phosphorites du Quercy, France
No full textPlesiotortrix edwardsi Rochebrune, 1884 a été l’un des premiers taxons de serpents décrits dans les Phosphorites du Quercy, France. Le taxon a été établi dans la seconde moitié du xixe siècle, à partir de trois vertèbres articulées trouvées dans une localité inconnue du Quercy. À l’origine, seule une brève description était fournie, accompagnée d’une lithographie représentant le spécimen holotype en vues antérieure et dorsale. Néanmoins, Plesiotortrix Rochebrune, 1884 est depuis fréquemment apparu dans la littérature sur les ophidiens au cours des 140 dernières années et même des diagnoses modifiées ont été proposées, mais ses affinités exactes restent obscures. J’ai étudié l’holotype ainsi que le seul spécimen connu et je fournis ici, pour la première fois, des photographies et des comparaisons détaillées avec d’autres serpents. Plusieurs inexactitudes sont identifiées entre la lithographie originale et le spécimen réel, qui ont inévitablement affecté les comparaisons anatomiques et les interprétations taxonomiques passées. Plesiotortrix est probablement attribuable aux Constrictores, mais une détermination plus précise, au niveau familial, n’est pas possible. De plus, le caractère incomplet de l’holotype et du seul spécimen connu, couplé à une variation intracolumnaire totalement inconnue du taxon, m’amène à considérer Plesiotortrix edwardsi comme un nomen dubium.Plesiotortrix edwardsi Rochebrune, 1884 was one of the first snake taxa to be described from the Phosphorites du Quercy, France. The taxon was established in the second half of the 19th century, based on three articulated vertebrae that were found in an unknown locality in the area of Quercy. Originally, only a brief description was provided coupled with a lithograph that depicted the holotype specimen in anterior and dorsal views. Nevertheless, Plesiotortrix Rochebrune, 1884 has since frequently appeared in ophidian literature across the past 140 years and even emended diagnoses have been proposed, but still, its exact affinities have been obscure. I investigated the holotype and only known specimen and I am herein providing, for the first time, photographs and detailed comparisons with other snakes. Several inaccuracies are identified among the original lithograph and the actual specimen, which have inevitably affected past anatomical comparisons and taxonomic interpretations. Plesiotortrix is probably belongs Constrictores but a more precise, family level, determination is not possible. Moreover, the incompleteness of the holotype and only known specimen, coupled with a totally unknown intracolumnar variation of the taxon, lead me to consider Plesiotortrix edwardsi to be a nomen dubium.</p

The species status of Sphecodopsis leonis (Cockerell, 1933) sp. rev. is restored, and the previously unknown males of S. capensis (Friese, 1915) and S. vespericena Eardley, 1997 are described for the first time. Sphecodopsis argyrura (Cockerell, 1933) is treated as a nomen dubium. Within Sphecodopsis seven species groups are recognised and redefined. All available species are imaged and included in a key to facilitate their identification.</p
New insights into <i>Diplogastrellus</i> Paramonov, 1952 (Nematoda: Rhabditida: Diplogastroidea) with three novel and three known species from India
No full textThree new and three known species of the genus Diplogastrellus Paramonov, 1952 are described and illustrated from India. Diplogastrellus didelphis sp. nov. is characterised by a narrow stoma; a medium-sized dorsal tooth with ventrally directed apex; an oblong median bulb, a small pyriform basal bulb; an amphidelphic reproductive system; a large uterine pouch; ventrally arcuate spicules with a 90º curvature; a stout gubernaculum, proximally notched with a long dorsal arm, distally with a sleeve and nine pairs of genital papillae. Diplogastrellus longipharyngis sp. nov. is characterised by a short tubular stoma; a medium-sized ventrally directed dorsal tooth; an ovoid median bulb and a long isthmus; heavily cuticularized almost straight spicules; a keel-like triangular gubernaculum proximally notched, a caudal margin interrupted and nine pairs of genital papillae. Diplogastrellus robustus sp. nov. is characterised by a medium-sized dorsal tooth with a ventrally directed apex; an ovoid median bulb; a mono-prodelphic or amphidelphic reproductive system; robust spicules, with a blunt distal tip; a boat-shaped gubernaculum with a prominent distal sleeve and nine pairs of genital papillae. Three known species, viz., D. gracilis, D. graciloides and D. monhysteroides are redescribed/illustrated with emended diagnosis and SEM details. The comparative analysis of morphometrics and morphological traits as well as cladogram based on morphological characters are provided besides their biogeographic distribution.</p
Notes sur l’anatomie florale d’<i>Annona haematantha</i> Miq. : une corolle annonacéenne inattendue et spécialisée
No full textL’espèce sud-américaine Annona haematantha Miq. présente une corolle très curieuse, qui était auparavant interprétée comme deux corolles concentriques. Une étude anatomique a été entreprise afin de résoudre cette question. Les pétales externes et internes sont fusionnés à leur base en un large tube non apprimé sur les organes reproducteurs. Les pétales internes sont modifiés adaxialement en glandes proéminentes sur les 3/4 de leur longueur. La vascularisation réceptaculaire, ainsi que les structures androéciale et gynoéciale sont par ailleurs tout à fait conformes à l’architecture florale des autres espèces connues d’Annona L. Une telle adaptation localisée suggère un processus de pollinisation particulier et élargit la gamme des tissus nutritifs observés dans les fleurs d’Annonaceae. Le système de pollinisation implique probablement une anthèse nocturne, la thermogénèse, l’émission d’odeurs et la cantharophilie.The South-American species Annona haematantha Miq. exhibits a very puzzling corolla, which was previously interpreted as two stacked corolla tubes. An anatomical study was undertaken in order to solve this question. The outer and inner petals are fused at their base in a wide tube not appressed to the reproductive organs. The inner petals are adaxially modified into prominent glands on the proximal 3/4 of their length. The receptacular vasculature, as well as androecial and gynoecial structures are otherwise wholly in accordance with the floral anatomy of other known Annona L. species. Such a localized adaptation suggests a peculiar pollination process and widens the range of nutritious tissue patterns recorded in Annonaceae flowers. The pollination system probably involves night-flowering, thermo-genesis, scent emission, and intervention of scarab beetles.</p
Nouvelle espèce du genre cryptique <i>Gloiocladia</i> J.Agardh (Faucheaceae, Rhodophyta) des écosystèmes coralliens mésophotiques hawaïens
No full textLa Crypsis – similitudes morphologiques élevées des thalles adultes d’espèces d’algues distinctes – est un défi courant dans la taxonomie des algues, où plusieurs taxons sont caractérisés comme la même espèce en raison de morphologies identiques. Les genres d’algues comportant des espèces cryptiques et des morphologies similaires peuvent contenir des sous-estimations de la diversité et de l’endémisme. Des études approfondies des écosystèmes coralliens mésophotiques (MCE ; d’environ 30 à >150 m de profondeur) ont révélé des niveaux élevés d’endémisme dans l’archipel hawaïen à l’aide d’analyses basées sur des séquences d’ADN complétées par des analyses morphologiques. Nous caractérisons ici les spécimens collectés à la fois dans le monument national marin de Papahānaumokuākea et dans les principales îles hawaïennes correspondant au genre Gloiocladia J.Agardh, qui était auparavant représenté à Hawai’i par une seule espèce subtidale (G. iyoensis (Okamura) R.E.Norris). Les analyses phylogénétiques utilisant à la fois des marqueurs chloroplastiques (ribulose-1,5-biphosphate carboxylase/oxygénase) et mitochondriaux (sous-unité 1 de la cytochrome oxydase) ont révélé trois clades de spécimens hawaïens présentant de fortes divergences entre les séquences d’ADN. Cependant, la morphologie globale de ces spécimens est presque identique, à l’exception du nombre de couches et de la taille des cellules corticales et médullaires. Cette étude étend la gamme de profondeur de G. iyoensis aux MCE supérieurs (63 m, confirmant une occurence précédente sur un échantillon de drague à 66 m) et a révélé une espèce exclusive aux MCE, G. laukuamoo K.R.Allsopp, F.P.Cabrera & A.R.Sherwood, sp. nov., ainsi qu’une espèce intertidale (description formelle en attente d’analyse de collections ultérieures), présente dans l’archipel hawaïen, notamment le monument national marin de Papahānaumokuākea (PMNM) et les principales îles hawaïennes.Crypsis – high morphological similarities of adult thalli of distinct species of algae – is a common challenge in algal taxonomy, where multiple taxa are characterized as the same species due to identical morphologies. Algal genera with cryptic species and similar morphologies may contain underestimates of both diversity and endemism. Extensive studies of Mesophotic Coral Ecosystems (MCEs; from c. 30 to >150 m depths) have revealed high levels of endemism in the Hawaiian Archipelago using DNA sequence-based analyses augmented by morphological analyses. Here, we characterize specimens collected from both the Papahānaumokuākea Marine National Monument and the Main Hawaiian Islands corresponding to the genus Gloiocladia J.Agardh; previous reports from Hawai‘i included only a single subtidal species (G. iyoensis (Okamura) R.E.Norris). Phylogenetic analyses using both plastidial (ribulose-1.5-biphosphate carboxylase/oxygenase) and mitochondrial (cytochrome oxidase subunit 1) markers revealed three clades of Hawaiian specimens with strong sequence divergence. However, the gross morphology of these specimens was nearly identical, except for small differences in the number of layers and sizes of cortical and medullary cells, which can easily be overlooked. This study extended the depth record of G. iyoensis to 63 m (aside from a previous report of a dredge sample from 66 m) and revealed one new species exclusive to MCEs (described here as G. laukuamoo K.R.Allsopp, F.P.Cabrera & A.R.Sherwood, sp. nov.), as well as one new intertidal species (formal description awaiting analysis of further collections) present in the Hawaiian Archipelago, including the Papahānaumokuākea Marine National Monument (PMNM) and the Main Hawaiian Islands.</p
Three new species of ischnoceran lice (Psocodea: Phthiraptera) from birds in China, with a key to the <i>Lagopoecus</i>-group of genera
No full textThree new species of chewing lice (Psocoptera: Phthiraptera: Ischnocera) are described from hosts in China based on specimens deposited at the Natural History Museum of China. Galliphilopterus latifrons sp. nov. is described from Arborophila gingica (Gmelin, 1789) as the second known species of this genus. The relationships of the genus Galliphilopterus are discussed, and it is suggested this genus is close to Mulcticola Clay & Meinertzhagen, 1939. Lagopoecus liui sp. nov. is described from Lophura nycthemera (Linnaeus, 1758). Species groups within Lagopoecus Waterston, 1922 are suggested, based on a partial morphological review of the genu. A key to the species groups of Lagopoecus and presumed closely related genera is provided. Turdinirmus calleipus sp. nov. is described from specimens that likely constitute stragglers, and the natural host of this species is here considered unknown.</p
Three new species of Mecoptera (Insecta, Antliophora) from Yunnan, China
No full textThe hangingflies (Bittacidae Handlirsch, 1906) and the scorpionflies (Panorpidae Latreille, 1802) are the two largest groups within the holometabolous order Mecoptera Packard, 1886. In this paper, a new hangingfly and two new scorpionflies are described: 1) Bittacus yunlongensis sp. nov., characterized by the greatly elongated and finger-shaped distal portion of male epandrial lobe, and greatly elongated upper and lower branches of proctiger; 2) Dicerapanorpa dajinhuang sp. nov., recognized mainly by the ventral branch of male parameres bearing small barbs on inner margin; and 3) D. jialiangjiei sp. nov., characterized by the bifurcated middle branch and sinuate distal portion of dorsal branch of male parameres. These new discoveries enrich the known species number of Bittacus Latreille, 1802 from one to two and Dicerapanorpa Zhong & Hua, 2013 from twelve to fourteen in Yunnan Province. </p

Based on the type material and fresh specimens, Rhinocricus fundipudens (Karsh, 1881) is transferred to the new genus Colombocricus gen. nov. and its redescription is presented. In addition, a key to males and a map of distribution of the genus is provided.</p
<i>Epidaus batxatensis</i> and <i>Epidaus konkakinhensis</i>, two new species of the genus <i>Epidaus </i>Stål (Insecta: Hemiptera: Reduviidae: Harpactorinae) from Vietnam
No full textThe genus Epidaus Stål, 1859 includes 26 valid species, distributed widely in the Oriental and Sino-Japanese realms. Among them, four species, Epidaus bachmaensis Truong, Zhao & Cai, 2006, E. famulus (Stål, 1904), E. longispinus Hsiao, 1979, and E. sexspinus Hsiao, 1979, were recorded and described from Vietnam. In this study, we conduct the examination of species of the genus Epidaus collected from Vietnam based on an integrative taxonomy, including morphological examination, morphometric analyses (Principal Component Analyses), molecular phylogenetic analyses (Bayesian Inference Analyses), and species delimitation analyses (Assemble Species by Automatic Partitioning and Bayesian implementation of the Poisson Tree Processes model). As a result, two new species of the genus Epidaus Stål, 1859, i.e., Epidaus batxatensis Truong, Nguyen & Ha sp. nov. and Epidaus konkakinhensis Truong, Nguyen & Ha sp. nov., are herein discovered and described.</p
