Mussaenda yunnanensis sp. nov. (Rubiaceae), a new functionally dioecious species from Yunnan,China

Mussaenda yunnanensis, a new dioecious species of Rubiaceae from Yunnan Province, China, is described and illustrated. The new species can be recognized by its slender stem, congested‐cymose inflorescences and long corolla tubes. Differences between M. yunnanensis and two morphologically similar species (M. pubescens and M. antiloga) are presented. We also provide a key to all dioecious species of Mussaenda in China. The delimitation of the new species is further supported by molecular phylogenetic analyses based on eight plastid loci.     

Didymocarpus tonghaiensis sp. nov. (Gesneriaceae) from Yunnan,China

Didymocarpus tonghaiensis J. M. Li & F. S. Wang sp. nov. from Yunnan, China, is illustrated and described. It is morphologically similar to D. stenanthos C. B. Clarke, but differs by having a densely glandular peduncle, 5‐lobed calyx with lobes that are free to the base, larger corolla, anther with white woolly hairs and a densely glandular‐hairy capsule.     

A new species of Chirita (Gesneriaceae) from Yunnan,China

A new species of Gesneriaceae, Chirita maguanensis Z.Y.Li, H.Jiang & H.Xu, is described from Southern Yunnan, China. It is similar to C. eburnea Hance in its large, fleshy, white and parallel‐veined bracts, but differs by having broad and oblique leaves with a repand–crenate or crenate margin, suborbicular bracts, membranous, white calyx, purple corolla‐tube, 2‐parted lower lip of stigma and lower disc. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 269–273.     

A new genus of monstrilloid copepods (Crustacea) with anteriorly pointing ovigerous spines and related adaptations for subthoracic brooding

Maemonstrilla gen. nov. , known exclusively from females, is proposed for Monstrilla longipes A. Scott, 1909, M. turgida A. Scott, 1909, and five new species from coral reef plankton in the Ryukyu Islands, Japan: Maemonstrilla hyottoko sp. nov. (type species), M. polka sp. nov. , M. spinicoxa sp. nov. , M. simplex sp. nov. and M. okame sp. nov. A syntype of M. turgida was examined, but the holotype of M. longipes is lost; the latter species, being similar to several of the new species, is regarded as unidentifiable, and the identity of specimens assigned to it by several authors is put in doubt. Until now, all known female monstrilloids have had posteriorly trailing ovigerous spines, but in Maemonstrilla gen. nov. these spines point anteriorly and hold the egg mass between the legs beneath the thorax. This is the first known instance of subthoracic brooding in a planktonic copepod; its functional significance is discussed, and brooding habits of non‐planktonic copepods are briefly reviewed. The intercoxal sclerites of legs 1–4 in Maemonstrilla gen. nov. are very wide, making room for the eggs. In all species except M. turgida comb. nov. , the inner seta of the proximal segment of each leg ramus is either absent or reduced to a nub; this may lessen interference of the egg mass with leg movement. All species have a uniramous leg 5 with two setae, except M. turgida comb. nov. (biramous with setae on both rami); M. turgida comb. nov. is evidently the sister‐group of its congeners, each sister‐group in the genus being defined by additional autapomorphies. Scanning electron micrographs of all the Ryukyuan species except M. simplex sp. nov. are provided; these constitute a preliminary survey of monstrilloid integumental organs and cuticular ornamentation. Among the unusual features are two lobes at the base of the coxa in legs 1–4 of M. polka sp. nov. and M. spinicoxa sp. nov. and two pairs of posterodorsal spine‐like scales on the first and second free pedigers of M. turgida comb. nov. Newly hatched nauplii of M. okame sp. nov. , examined by scanning electron microscopy, are generally similar to those of Monstrilla hamatapex Grygier & Ohtsuka, 1995, but with a different mandibular structure in which the distal hook and seta clearly represent the endopod, not enditic armament of the basis. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 152 , 459–506.     

Taxonomic revision of the tribe Hymenodictyeae (Rubiaceae, Cinchonoideae)

The palaeotropical tribe Hymenodictyeae Razafim. & B. Bremer, belonging to the otherwise predominantly Neotropical subfamily Cinchonoideae  s.s. (coffee family or Rubiaceae), is revised here. The tribe as presently circumscribed contains two genera, Hymenodictyon Wall. and Paracorynanthe Capuron ex J.-F. Leroy, and is distinct from the other Cinchonoideae tribes with capsular fruits in having stipules bearing large, deciduous colleters on the margins, valvate corolla aestivation, and lenticellate capsular fruits that contain elongate, bilaterally flattened, and accrescent placentae. We recognize 22 Hymenodictyon species, including four new species ( H. antakaranensis sp. nov. , H. epiphyticum sp. nov. , H. madagascaricum sp. nov. , and H. tsingy sp. nov. ), and the two described species of Paracorynanthe . Hymenodictyon is distinguished from its sister genus, Paracorynanthe , by simple or compound spicate, racemose or thyrsoid inflorescences and corolla lobes without any appendages, rather than compound umbelliform inflorescences and corolla lobes prolonged by ciliate appendages. A full taxonomic treatment, keys, and distribution maps of all recognized Hymenodictyon and Paracorynanthe species are provided. Five lectotypes and one neotype are designated. Finally, six Hymenodictyon species are illustrated for the first time.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 152 , 331–386.     

A new species of Cycas (Cycadaceae) from Karnataka,India

Cycas swamyi Singh & Radha, sp. nov. (Cycadaceae) is described and illustrated from Karnataka, India. This new species has been confused with Cycas circinalis L., which is found in the Western Ghats. However, on the basis of its habit, characteristic isotomous‐type dichotomous branching, pinnae anatomy, mega‐ and microsporophyll morphology and seed anatomy, it has been segregated from C. circinalis and is described here as a new species. The distribution and conservation status are also discussed. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 430–435     

Stromanthe bahiensis sp. nov. (Marantaceae), endemic to southern Bahia State,Brazil

Stromanthe bahiensis Yoshida‐Arns, Mayo & J. M. A. Braga sp. nov. (Marantaceae) is described as an endemic to the Atlantic Forest coast of southern Bahia State in Brazil. It is similar to S. hjalmarssonii (Körn.) Petersen, which is restricted to Central America, but differs from it by the following characteristics: petiole 14–70 cm long, leaf blade oblong‐ovate to ovate‐lanceolate, fertile bracts 18–30×2–4 mm, narrowly lanceolate to ovate‐lanceolate, sepals 4–6 mm long, corolla lobes 3.0–3.5 mm long, outer staminodes 2.0–3.5×1–2 mm, pale bluish or purplish, callose staminode 2–3×1–2 mm, cucullate staminode 2–3 mm long and ovary hirsute. The new species is described and illustrated with diagnostic characters, taxonomic comments and remarks on its conservation status.     

Provannid and provannid‐like gastropods from the Late Cretaceous cold seeps of Hokkaido (Japan) and the fossil record of the Provannidae (Gastropoda: Abyssochrysoidea)

A fauna of provannid and provannid‐like shells is described from Upper Cretaceous seep carbonates in Hokkaido, Japan. We describe two new provannid species, Provanna tappuensis sp. nov. and Desbruyeresia kanajirisawensis sp. nov. , with preserved protoconchs of unquestionable provannid type with decollate apex. This material confirms the occurrence of Provannidae as early as the Middle Cenomanian. We also describe Hokkaidoconcha gen. nov. and a new family Hokkaidoconchidae fam. nov. , with two named species, H. hikidai sp. nov. and H. tanabei sp. nov . Hokkaidoconchidae are possibly related to the Provannidae, judging from a similar, but not decollate larval shell, although the juvenile teleoconch whorls differ in being of a general cerithimorph appearance and the details of the aperture are unknown. Furthermore, we review the published fossil record of Provannidae and Abyssochrysidae, and we consider that in those older than the Eocene, there is no evidence preserved that unequivocally supports a position there. The Jurassic Acanthostrophia acanthica from Italy seems to be the oldest known record of Abyssochrysidae, and the most reliable occurrence of the family, older than from the Miocene. Other fossil, pre‐Miocene species that have been classified in the Abyssochryssidae are provisionally referred to Hokkaidoconchidae. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 421–436.     

Microula pentagona sp. nov. and M. galactantha sp. nov. (Boraginaceae) from the eastern Qinghai‐Tibetan Plateau

Microula pentagona W. T. Yu, S. T. Chen & Z. K. Zhou sp. nov. and M. galactantha W. T. Yu, S. T. Chen & Z. K. Zhou sp. nov. (Boraginaceae) from the eastern Qinghai‐Tibetan Plateau are described and illustrated. Microula pentagona is characterized by the pentagonal dark purple pubescent corolla throat, whereas M. galactantha is distinct by its white flowers and a nutlet attachment near the apex. The diagnostic features of the two new species are compared with other species of the genus.

Millettia weizhii (Fabaceae: Millettieae), a new species with four‐winged pods from a limestone area in Yunnan,China

Millettia weizhii sp. nov. (Fabaceae), a tree species bearing pods with 4 wings is described and illustrated from a limestone area in Yunnan, China. Fruiting specimens of the new species were previously identified as Millettia tetraptera Kurz, a species recorded from Myanmar and India (West Bengal), but examination of specimens and data from our field survey show that the new species is easily distinguished by having longer and stipitate pods, much shorter pseudoracemes with 2 flowers at each node, white and longer corolla, triangular calyx lobes and more and narrower leaflets. The new species should be placed in the Merrillii/Xylocarpa‐group of Millettia sect. Fragiliflorae Dunn based on morphological characters.     

Picrorhiza tungnathii sp. nov. from western Himalaya,India

The new species Picrorhiza tungnathii Pusalkar is described and illustrated from the western Himalaya, India. It is distinguished from the allied P. kurrooa Royle ex Benth. by being 10–25 cm tall, having a moderately dense, (10–)15–25‐flowered spike, a zygomorphic, 2‐lipped, glandular‐ciliate corolla that is equaling or slightly exceeding the calyx and partly visible or sub‐exserted between the calyx lobes, a conspicuously long (longer than the corolla lobes), curved corolla tube (1/2–4/5 the length of the calyx), unequal corolla lobes that are ovate‐lanceolate to lanceolate, acute to sub‐acuminate and moderately ciliate, a mid‐lobe of the upper lip that is obliquely erect, galeate with retuse or emarginate apex, lateral corolla lobes that are slightly smaller than the mid‐lobe of the upper lip, a lower corolla lip that is slightly shorter than the lateral lobes, obliquely erect or spreading, didynamous, long‐exserted (2–3 times the corolla) stamens, pollen of the Paederota‐type and a style that is 2–3 times as long as the corolla.     

Two new species of Linaria section Linaria (Scrophulariaceae‐Antirrhineae) from Iran

Linaria azerbaijanensis and Linaria shahroudensis are described as new species from the Azerbaijan and Semnan provinces of Iran, respectively, belong to section Linaria.The new species are compared to their closest relative Linaria lineolata. Linaria azerbaijanensis differs from L. lineolata in having shorter bracts, a shorter corolla, shorter spur and smaller capsules and a different microsculpturing pattern of the testa cells. Linaria shahroudensis differs from L. lineolata in having shorter stems, shorter calyx‐lobes, a longer spur, a smaller capsule and a different microsculpturing pattern of the testa cells. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 734–742.     

Primulina petrocosmeoides sp. nov. (Gesneriaceae) from Guangxi,China

Primulina petrocosmeoides Bo Pan & Fang Wen sp. nov. (Gesneriaceae) from Guangxi, China, is described and illustrated. This new species is similar to P. weii Mich. Möller & A. Weber, but differs from it in leaf blade ovate to elliptical, 1.0 × 0.8 to 2.5 × 2.0 cm, leaf base broadly cuneate, cymes 5–16, 2–6‐flowered, bracts narrowly lanceolate, calyx lobes lanceolate, 4.0–6.5 mm long, corolla bluish purple, 1.2–1.5 cm long, pubescent outside but glabrous inside, filaments purple, pubescent, staminodes 3, stigma trapezoid with its apex lobed to the middle and with dense short papillae.     

A new family of lithophoran Proseriata (Platyhelminthes), with the description of seven new species from the Indo‐Pacific and South America,and the proposal of three new genera

In this contribution a new representative of the taxon Meidiama Marcus, 1946, Meidiama uruguayensis sp. nov. , from Uruguay, is described, as are six more new species, for which three new genera are proposed: Dreuxiola philippi gen. nov. sp. nov. , from the French subantarctic archipelago Kerguelen; Yorknia aprostatica gen. nov. sp. nov. ; Serrula byronensis gen. nov. sp. nov. ; Serrula maxillaria sp. nov. ; Serrula concharum sp. nov. ; and Serrula acuta sp. nov. , from eastern Australia and Tasmania. Arguments are presented to propose a new taxon to contain these new species, rather than include them in the Archimonocelididae Meixner, 1938 (of which Meidiama has been considered a member so far), as well as to remove the Calviriinae Martens & Curini‐Galletti from the Archimonocelididae to become a separate taxon Calviriidae. Possible autapomorphies for the three families are discussed. It is also concluded that, with the present state of our knowledge, no sound indications can be given about close relationships. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155 , 759–773.     

Deep-sea Bodotriidae (Crustacea: Cumacea) from New Caledonia, Fiji and Indonesia

Cumaceans (Crustacea: Peracarida) belonging to the family Bodotriidae collected between 206 and 3680 m depth, during the French campaigns BIOCAL and BIOGEOCAL in waters of New Caledonia, KARUBAR in Indonesia and BORDAU 1 around Fiji were studied. The 93 specimens belonging to this family were assigned to 11 species, ten of them new to science, namely Cyclaspis variosculpta sp. nov., Cyclaspis richeri sp. nov., Cyclaspis dictyota sp. nov., Cyclaspis decora sp. nov., Cyclaspis magna sp. nov., Cyclaspoides erugatus sp. nov., Alticuma? ectyphum sp. nov., Apocuma pacificum sp. nov., Hypocuma fragosum sp. nov. and Bathycuma coremium sp. nov. The genera Cyclaspoides and Hypocuma are recorded for the first time from the Pacific Ocean. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 152 , 227–254.     

A revision of the Cossulinae of Costa Rica and cladistic analysis of the world species (Lepidoptera: Cossidae)

The Cossidae are an economically important family of moths consisting of six subfamilies and more than 700 species globally. Their larvae are often of serious concern to forestry and horticulture in that they are known to bore in the branches and trunks of a wide range of trees and shrubs. Cossulinae is one of the six subfamilies of Cossidae and is restricted to the New World. As a result of this revision, the Costa Rican Cossulinae has been found to consist of five genera and 18 species. The phylogenetic relationships of all Cossulinae genera were analysed using the computer programs WinClada and NONA. Glandular organs new to Cossidae and the Lepidoptera have also been discovered. Four genera, Biocellata gen. nov. , Magulacra gen. nov. , Simplicivalva gen. nov. and Spinulata gen. nov. , and the following nine species are described as new: Biocellata bifida sp. nov. , Biocellata davisorum sp. nov. , Cossula buspina sp. nov. , Cossula duplexata sp. nov. , Cossula longirostrum sp. nov. , Cossula minutiloba sp. nov. , Simplicivalva ampliophilobia sp. nov. , Spinulata oblongata sp. nov. and Spinulata quasivinnea sp. nov. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 222–277.
