Laboulbenia exigua and related taxa (Ascomycetes,Laboulbeniales)

TheLaboulbenia exigua group comprises seven species. Three of these species are described as new to science, and two new varieties ofL. exigua and one new variety ofL. balazucii are distinguished and described. New taxa areL. yamadae, L. consobrina, L. gebleri, L. exigua var.yaeyamae, L. exigua var.melanolabiata andL. balazucii var.exilis. This fungus group is characterized by grayish yellow to gray-brown thalli with simple inner and outer appendages, dark-spotted or streaked receptacles, and perithecia containing narrow ascospores 3–4–(–5) µm in width; the species and varieties occur onChlaenius (Carabidae) and closely allied taxa. The bilobed apex of mature perithecium, owing to the rounded apices of the posterior apical cells of the outer wall cell rows, and 3-celled, curved inner appendage in young thalli, and the deciduous antheridium are also characteristic of this group.     

New or interesting Laboulbeniales (Ascomycetes) on Japanese chlaeniine beetles (Coleoptera,Carabidae)

Four species ofLaboulbenia were isolated from Japanese chlaeniines and are reported.Laboulbenia habui is described as a new species; it is possibly related toL. fasciculata. Laboulbenia habui is characterized by the proliferation and division of cell V, resulting in the formation of an obliquely superposed series of cells from which short, cylindrical cells arise in a double row, whereas there is a single row of cubical cells inL. fasciculata. Laboulbenia humilis is new for the Japanese mycoflora; antheridia of this fungus were observed for the first time; shape of the perithecial apex, persistent antheridia and the spore size suggest thatL. humilis is not closely related toL. exigua and its related taxa. ForL. proliferans andL. fasciculata, new chlaeniine hosts are listed and some supplemental notes are given.     

Notes onLaboulbenia stenolophi andLaboulbenia anoplogenii (Ascomycetes, Laboulbeniales)

Laboulbenia stenolophi is reported for the first time from Japan.Stenolophus iridicolor andS. propinquus are added as new hosts. The crowded antheridia and the protruding (bulging) cell IV are characteristic of this fungus, although thalli with an almost normal cell IV sometimes occur.Laboulbenia anoplogenii onAnoplogenius is easily distinguished from what has been calledL. anoplogenii onStenolophus, Astigis, Abacetus andChlaeminus by the following characters: 1) no crowded antheridia can be observed throughout thallus development, but many sterile long branches can be observed instead; 2) cell IV starts to undergo cell division early in thallus development; 3) cell V extends downward to the level of cell VII, rather than extending only as far as the perithecial basal cells; and 4) cell VI is usually longer and extends farther distally than cell III.Anoplogenius is the host genus ofL. anoplogenii and the records from other hosts represent misapplied names.     

Notes onLaboulbenia coneglanensis (Ascomycetes, Laboulbeniales) in Japan

Laboulbenia coneglanensis isolated from Japanese harpaline carabids is described and photographed. It is compared morphologically withL. flagellata from Japan and Europe, which is similar in appearance. The most important difference between the two species is in antheridial character and host range. Other characters such as coloration, perithecial shape, especially the shape of the perithecial apex, and size of ascospores are also useful for distinction.Laboulbenia ophoni var.dilatata described by Maire (1920) is regarded as a synonym ofL. coneglanensis.     

New records of the carabidicolous Laboulbeniales (Ascomycetes) of Japan (II)

Six carabidicolous species of Laboulbeniales are reported as new for the Japanese mycoflora. They areLaboulbenia finitima, L. separata, L. borneensis, L. manubriolata, Dimeromyces caribaeus, andDixomyces ornatus. In Japan, the former three species are parasitic onMochtherus luctuosus and the latter three species onPerigona nigriceps. Laboulbenia finitima occurs on the left legs (tarsi and tibiae);L. separata on the left elytral margin:L. borneensis on the pronotum;L. manubriolata on the pronotum and elytra;Dimeromyces caribaeus on the right inferior posterior surface of the prothorax (pronotal hypomeron); andDixomyces ornatus on the outer margin of the right elytron. Comments and photographs are given for each fungus.     

Three species of the genus Laboulbenia (Laboulbeniales) parasitic on Chydaeus bedeli (Coleoptera, Carabidae) from Asia

Three species of the genus Laboulbenia were recorded on Chydaeus bedeli (Coleoptera, Carabidae, Harpalini) from high-altitude localities in Asia. Laboulbenia obtusa was obtained from tarsi of the midlegs of the male hosts; Laboulbenia acrogeniodontis was on the margins of the elytra of the male and female hosts; and Laboulbenia polyphaga was on the elytra (near the apex) and the pronotum (at the base) of the male and female hosts. Each of the three species is distinct in the shape of the perithecia and the structure of the appendages.     

Calleida desenderi, new species from Ecuador (Coleoptera, Carabidae, Lebiinae)

Calleida desenderi Casale, sp. n., is described from Ecuador, Napo Province, surroundings of San Rafael. The new taxon is mostly characterized by the head and appendages rufous, the disc of elytra with marked metallic green reflection, the median lobe of aedeagus ring-like, and the endophallus with a long, twisted flagellum. A key for identification of the closer Neotropical species described so far is also provided.     

A new species of the genus Laboulbenia (Laboulbeniales) on Ophionea indica (Coleoptera, Carabidae, Odacanthini) from Taiwan

Laboulbenia ophioneae is described as a new species with illustrations. It is closely related to Laboulbenia celestialis and Laboulbenia asiatica because of some similarities in the morphology of appendages and perithecia. The present species from the latter two species can be distinguished by the shorter, inflated perithecia, the shorter receptacles, and the appendages consisting of more or less darkly colored, broader branches. This new species was found on elytra of Ophionea indica from Taiwan, which has been also known as a host of Laboulbenia polymorpha. A mature thallus noticed by Terada (2004) on the slide 673b (M. Ishikawa collection) and a young thallus illustrated by Sugiyama (1978, fig. 1-G as L. polymorpha) on 673d (M. Ishikawa collection) are both identified as L. ophioneae.     

New records of the carabidicolous laboulbeniales (Ascomycetes) of Japan

Six carabidicolous species of Laboulbeniales are reported as new for the Japanese mycoflora. They areDixomyces stomonaxi, Laboulbenia picardii, L. tenera, L. slackensis, L. aristata andL. kwangjuensis. Two forms ofD. stomonaxi are distinguished, one form of which resemblesD. nigromarginatus. A remarkable ornamentation consisting of a coillike pattern occurs on the receptacle ofL. picardii. InL. tenera andL. slackensis, the outer appendage has somewhat constricted, blackened septa near the base.Laboulbenia aristata andL. kwangjuensis have spirally arranged outer wall cells. Antheridia were observed inL. tenera, L. slackensis, L. aristata andL. kwangjuensis.     

Eucamaragnathus desenderi, a new ground beetle species from Africa (Coleoptera, Carabidae)

Eucamaragnathus desenderisp. n., a new ground beetle species of the tribe Hiletini, is described from eastern and southern Africa and dedicated to the recently deceased Belgian carabidologist Konjev Desender. The new taxon is known so far from localities in Zambia (Mukuku, southeast of Mansa) and in South Africa (Bothaville, south of Klerksdorp). The new species belongs to the Eucamaragnathus castelnaui group and is characterized by shape of pronotum, smooth or sparsely punctate pronotal transverse impression, characters of male genitalia and elytral striae continued to the apex. Illustrations of the habitus, the median lobe and its internal sac and several other morphological features are presented. An updated identification key to the African Eucamaragnathus species is given.     

Two new endemic species of the genus <Emphasis Type="Italic">Omphreus</Emphasis> (Carabidae: Coleoptera) from Montenegro

Two new species, viz. Omphreus (Omphreus) prekornicensis sp. n. (from Medjedje Peak, Mt. Prekornica, C Montenegro) and Omphreus (Omphreus) bjelasicensis sp. n. (from Biogradska Gora National Park, Mt. Bjelasica, E Montenegro), are described and diagnosed. Male and female genitalia and other taxonomically important characteristics are illustrated. The new species are clearly distinct from their closest congeners and represent endemic relicts inhabiting limited regions of the Dinaric mountain system in Montenegro.     

A new species of Ochridacyclops (Kiefer, 1937) (Copepoda, Cyclopoida) from Japan

A new species of cyclopoid copepod, Ochridacyclops nipponensis is described from Japan. This is the third species of the genus. The type material was collected from small streams in the mountainous regions in Shikoku. The new species can easily be distinguished from other members of genus by its 12-segmented antennule, by the proportional length of genital double-somite relative to the length of 3 free abdominal somites, and by the shape of caudal rami. The male is unknown.

Description of a new species of Platynus Bonelli from the Appalachian Mountains of eastern North America (Coleoptera, Carabidae)

A new species of the genus Platynus Bonelli, Platynus daviesi, is described from specimens collected in the Appalachian Mountains. The species is structurally most similar to Platynus parmarginatus Hamilton but differs in having the coloration of the body dorsally darker on average, the elytra proportionally longer and wider, the vertex and disc of pronotum with well impressed microsculpture, the elytral interval 3 with four or five discal setae in most specimens, and the median lobe of aedeagus less curved overall. DNA barcoding was performed on several species of eastern North American Platynus species and Platynus daviesi was found to be genetically distinct from Platynus parmarginatus. A key to the 12 species of Platynus found east of the Mississippi River is provided.
