Anatomical description and phylogenetic classification of the orbicular velvetfishes (Scorpaenoidea: Caracanthus)

Anatomical characters for two species of the orbicular velvetfishes (Caracanthus) are described, and the phylogenetic position of the genus among the superfamily Scorpaenoidea is estimated cladistically on the basis of morphological characters belonging to 112 transformation series. Caracanthus is nested within the family Scorpaenidae, having close relationships with Taenianotus and Pteroidichthys. Validity of the family Caracanthidae was not supported, Caracanthus being included within the Scorpaenidae.     

<Emphasis Type="Italic">Tubulideres seminoli</Emphasis> gen. et sp. nov. and <Emphasis Type="Italic">Zelinkaderes brightae</Emphasis> sp. nov. (Kinorhyncha,Cyclorhagida) from Florida

One new kinorhynch genus and species and one new species from the genus Zelinkaderes are described from sandy sediment off Fort Pierce, Florida. The new genus and species, Tubulideres seminoli gen. et sp. nov. is characterized by the presence of the first trunk segment consisting of a closed ring, the second segment of a bent tergal plate with a midventral articulation and the following nine segments consisting of a tergal and two sternal plates. Cuspidate spines are not present, but flexible tubules are located on several segments, and in particular concentrated on the ventral side of the second segment. Middorsal spines are present on all trunk segments and are alternatingly offset to a position slightly lateral to the middorsal line. Zelinkaderes brightae nov. sp. is characterized by its spine formula in having middorsal spines on trunk segments 4, 6 and 8–11, lateroventral acicular spines on segment 2, lateral accessory cuspidate spines on segments 2 and 8, ventrolateral cuspidate spines on segments 4–6 and 9, lateroventral acicular spines present on segments 8 and 9, and midterminal, lateral terminal and lateral terminal accessory spines on segment 11. The spine formula of Z. brightae nov. sp. places it in a position in between Z. submersus and a clade consisting of Z. klepali and Z. floridensis. The new findings on Z. brightae nov. sp. have led us to propose an emended diagnosis for the genus.     

New species of the genus <Emphasis Type="Italic">Scolecostigmina</Emphasis> and revision of <Emphasis Type="Italic">Cercospora cryptomeriicola</Emphasis> on conifers

Scolecostigmina chibaensis on Pinus parviflora is described as a new species. Cercospora cryptomeriicola Sawada on Cryptomeria japonica is transferred to the genus Pseudocercospora, based on the morphological characteristics of the type specimen and newly collected specimens.     

Fossil flowers and pollen ofLauraceae from the Upper Cretaceous of New Jersey

A fossil trimerous flower from the Turonian (ca. 90 MYBP, Upper Cretaceous) of New Jersey is described as a new genus in the familyLauraceae. The fossil flower is charcoalified and preserved in exceptional detail. This fossil specimen is particularly remarkable in that several pollen grains have been preserved; pollen grains ofLauraceae generally have very thin exine and are rarely preserved in the fossil record. Although the specimen is incomplete and lacks anthers, there are sufficient structural details preserved to permit an assignment to theLauraceae, as well as comparisons with the tribePerseeae. This new genus provides an important addition to our knowledge of systematic and structural diversity in CretaceousLauraceae.     

中国菌绒孢属的研究

菌绒孢是一个小属,已描述过的种约50个,都是植物寄生菌,有的引致植物病害还较 严重.本文报告了我国产的21个种,其中1个是新种,4个是新组合和2个新记录,对18个种均有英文描述和附图,新种还附有拉丁文简介,各个种的地区分布也予以载述.但文中有分布地区而其后未附HMAS标本号码者多系据《中国真菌总汇》(1979)转录.从前人的描述和我们研究中看出,菌绒孢属的属级特征有:(1)产孢细胞合生,合轴式多点全壁芽茁产孢;(2)分生孢子梗壁上和分生孢子顶端和基脐,或仅基脐的孢痕疤明显而厚;(3)分生孢子梗主要从表生甸甸菌丝上作为侧枝或顶生,但有的种也兼有从子座上 簇生的;(4)菌丝多结集成菌丝绳或攀缘于叶毛上;(5)分生孢子链生,少数种也不链生. 这就清楚表明菌绒孢属与尾孢菌属和色链隔孢属(Phaeoramularia)少不同之处在于,尾孢 菌和色链隔孢属二者的分生孢子梗均成簇发生且无表生匍匐菌丝,与极其近似的假尾孢属(Pseudocercospora)不同之处在于,后者的分生孢子梗也着生于表生匍匐状菌丝和簇 生于子座上,但其分生孢子梗和分生孢子的孢痕疤却薄而不明显,因而易于区别开.虽然1974年von Arx在其《纯培养产孢真菌的属》一书中,曾把菌绒孢属作为枝孢 属(Cladosporium)的异名,但这一观点我们未予接受,其理由已在《中国色链隔孢曲(1982)一文中加以说明,这里未予重述.上述这21个种除3个种,即M. costaricensis, M, pawlownicola和M. vaginae我们未获得研究材料,仅据以前作者的报导转录外,其余18个种均系根据标本进行的.这些标本,含M. merremiae sp. nov.的模式标本在内,均贮藏于中国科学院微生物研究所真菌标本室.

A new species of anglerfish (Lophiidae: <Emphasis Type="Italic">Lophiodes</Emphasis>) from the western Pacific

Lophiodes endoi sp. nov. is described from the western Pacific Ocean. Within the genus Lophiodes, the new species belongs in the L. mutilus group mainly defined by the absence of the fourth dorsal fin spine and differs from other species in the L. mutilus group in having a rounded esca with a paler tip, a third dorsal spine bearing a pair of black tendrils at two-thirds its length, 20–21 pectoral fin rays, a relatively short head, a relatively short illicium, a relatively short third dorsal spine, and a relatively long fifth dorsal spine, reaching the third soft dorsal fin ray when folded back. Comments on a similar species, L. bruchius, newly collected from the Kyushu–Palau Ridge, and notes on the distribution of congeneric species in the northwestern Pacific are provided.     

小柱芥属植物分类及地理分布研究

小柱芥属(Microstigma Trautv.)为十字花科(Brassicaceae)一寡种属,目前由于缺乏系统研究,存在属内物种划分不明确,地理分布不确定等问题。该文通过在甘肃、内蒙古的标本采集,以及GBIF的标本记载和相关文献的查阅,对小柱芥属植物的形态特征和地理分布进行了详细描述,确定了小柱芥属内的物种数目并编制了属内物种检索表,绘制了地理分布图。结果表明:支持尤那托夫小柱芥(Microstigma junatovii)为一个独立的种,同时该种为中国新分布记录种;确定小柱芥属为蒙古高原近特有属,含4个种。该研究不仅丰富了中国小柱芥属的物种多样性,为小柱芥属的植物鉴定提供了理论依据,也为蒙古高原植物区系、植被等相关研究积累了新资料。     

Echinogobius hayashii, A new genus and species of gobiidae

Echinogobius hayashii, a new genus and species of Gobiidae is described, based on 11 specimens from Japan and Australia. This genus is distinguishable from all other gobiid genera in having the following combination of characters: first spine of first dorsal fin hard and straight, about 1.5 times second spine in thickness; first spine of second dorsal fin hard, with similar thickness as first soft ray of second dorsal fin, supported by two normally-sized pterygiophores; snout convex; preopercular spine absent; predorsal scales absent; all scales cycloid. The species occurs between 1–20 m in clear water on clear sandy bottoms influenced by fast tidal currents. Based on our observations, it is not associated with an alpheid shrimp.     

<Emphasis Type="Italic">Vanderhorstia papilio</Emphasis>, a new shrimp-associated goby from the Ryukyu Islands,Japan (Perciformes: Gobiidae: Gobiinae), with comments on the limits of the genus

A new gobiid fish, Vanderhorstia papilio, is described based on a single specimen (40.9mm SL) captured from a sandy-mud bottom at a depth of 45m in a protected bay of Iriomote-jima Island, Ryukyu Islands, Japan. It is distinguished from congeners in having the following combination of characters: 11 segmented dorsal-fin rays; 11 segmented anal-fin rays; 27 longitudinal scales; 11 predorsal scales; third spine of first dorsal fin elongate, filamentous, and longer than preceding spine; fifth and ninth branched caudal-fin rays elongate, filamentous, and forming bifurcated caudal fin; fifth and ninth branched caudal-fin rays with a single branch in each; cephalic sensory-papillae row a comprises three widely-spaced papillae; when live or fresh, numerous small yellow spots scattered on head, body, and dorsal fins; dusky yellowish-brown vertical bar below eye; four dark gray-brown saddles on body, in addition to a similarly colored large blotch at midlateral caudal-fin base. The limits and diagnosis of the genus Vanderhorstia are discussed.

记述广东弹尾纲 1 新种广东丽虫兆Callyntrura (Javaphysa) guangdon gensis sp. nov.,该新种与C. (J.) javana Yosii,1992 在上唇和下唇上比较相似,但是它们在体色、齿节刚毛、头部 V0 大毛、胸部第2节毛序有较大的区别。     

Cookeolus spinolacrymatus sp. nov., a Late Pliocene priacanthid fish from Okinawa, Japan

A new fossil priacanthid fish,Cookeolus spinolacrymatus, is described on the basis of a single specimen from the Late Pliocene Shinzato Formation, Shimajiri Group, Miyagi-shima, Okinawa, Japan. This species is distinguished from the Recent speciesC. japonicus (Cuvier, 1828) by having a strong spine on the anterior portion of the lacrymal. The specimen was identified as a small benthic adult, or large juvenile, based on comparison with pelvic fin length development in the Recent species.

描述了采自四川西部山区竹上的柄锈菌一新种,即寄生在箭竹Sinarundinaria nitida(Mitf.) Nakai上的箭竹柄锈菌Puccinia sinarundinariae J-y. Zhuang & S.-x. Wei。模式标本保藏在中国科学院微生物研究所真菌标本室。     

<Emphasis Type="Italic">Adelobotrys atlantica</Emphasis> (<Emphasis Type="Italic">Melastomataceae: Merianieae</Emphasis>): the first species of <Emphasis Type="Italic">Adelobotrys</Emphasis> from Brazil’s Mata Atlântica

Summary  A new species of Adelobotrys DC., A. atlantica Schulman, is described and illustrated. This is the first record of the genus in the Atlantic rainforests of Brazil. The only known specimen of the new species was collected in 1943 close to the sizeable city of Ilhéus in an area that has probably now been converted to managed land. It is therefore possible that A. atlantica is already extinct.     

中国苦苣苔科植物新资料——小花线柱苣苔

该文报道了产自中国西藏自治区墨脱县境内的线柱苣苔属(Rhynchotechum Blume)中国分布新记录——小花线柱苣苔(R. parviflorum Blume)。该新记录种常生长在林中溪流附近的崖壁以及次生林下阴湿生境中,主要辨别特征为叶基本对生,花萼裂片被绢毛,花梗被黄褐色绒毛,花冠筒较小,子房具短柔毛,果无毛至微柔毛。印度学者于2020年记载为印度新分布,而原始文献中记录的凭证标本采集点位于中国西藏自治区墨脱县境内,故对原文记述的产地信息提出质疑。同时,在前人的研究中部分馆藏的线柱苣苔属植物标本被认定为该新记录种,在此一并提出该新记录种在中国的分布地理信息和详细描述。     

On the taxonomic status of the Antarctic amphipod crustacean genera Eclysis (Astyridae) and Bathypanoploea (Stilipedidae), with partial redescription of their type species and description of Bathypanoploea polarsterni n. sp.

The monotypic genus Eclysis K.H. Barnard, 1932 and its type species, E. similis Barnard, are redescribed based upon a newly discovered second specimen. The genus Bathypanoploea Schellenberg, 1939 is reviewed; B. schellenbergi Holman and Watling, 1983 is fixed as the type species. B. polarsterni n. sp. is described; Alexandrella pulchra Ren in Ren and Huang, 1991 is a new junior synonym of B. schellenbergi. The morphology of Eclysis and Bathypanoploea is examined, as well as their relationships to the Astyridae and Stilipedidae.See also Electronic Supplement at: http://www.senckenberg.de/odes/05-03.htm     

Phylogenetic placement of <Emphasis Type="Italic">Marasmiellus juniperinus</Emphasis>

Recent collections and the type specimen of Marasmiellus juniperinus, the type species of the genus, were examined. Phylogenetic placement, based on ribosomal large subunit (LSU) and internally transcribed spacer (ITS) sequences, is within the lentinuloid clade, nested among Gymnopus taxa. This placement dictates genus name usage and phylogenetic position of other putative species of Marasmiellus. The mating system is tetrapolar.     

Achilaophonte maxima gen.n., spec.n., a new taxon of the Laophontidae (Copepoda,harpacticoida) from the high Antartic (Weddell Sea)

Male and female of a new genus and species of the family Laophontidae, Archilaophonte maxima, are described. The specimen was found in the high Antartic (Weddell Sea) and apprears to be the most primitive genus up to now within the superfamily Laophontoidea as defined by Huys (1990). Based on its setation of legs and mouth parts, however, it can be placed unequivocally into the family Laophontidae. Archilaophonte maxima gen. n. shows close affinities to the laophontid genus Esola Edwards 1891. Both genera form a monophyletic group which is interpreted here as the first and most primitive offshot in the evolution of the Laophontidae. The synapomorphies of the former lineage are the shape of the protopodite of the P1 and shape and setation of the female P5.
