[Ichthyology • 2014] Gymnotus capitimaculatus • A New Species of Electric Fish (Gymnotiformes: Gymnotidae) from rio Jucuruçu basin, northeastern Brazil

Gymnotus capitimaculatus 
 Rangel-Pereira, 2014 

A new species of Gymnotus, from the G. pantherinus species-group, is herein described from the rio Jucuruçu basin, a coastal river drainage located in the southern part of Bahia state, northeastern Brazil. Gymnotus capitimaculatus sp. n. differs from all congeners by having an pair of round blotches anteriorly positioned or under vertical passing through eye, on ventral portion of the head. Furthermore, Gymnotus capitimaculatus also differs from all members of the G. pantherinus species-group by having the following unique combination of characters states: tail with an unique series of bands or round spots; precaudal portion of trunk without bands but either with rounded and/or vermiculated spots; forty-five precaudal vertebrae; nine scales above lateral line at mid-body; anal-fin base length 75.2–78.6 % of TL; anus-anal fin length 101.4–122.8 % of HL; and branchial opening 38.5–45.0 % of HL.

Key words: Atlantic Forest, Biodiversity, electric eels, Gymnotus pantherinus complex, Knife-fish, taxonomy

Distribution. Known only from rio do Ouro, a tributary of the rio Jucuruçu, Itamaraju municipality, Bahia state, northeastern Brazil.

Etymology. Named capitimaculatus from the Latin subject capitis (head) and adjective maculatus (blotchy), due to the presence of a pair of blotches in the ventral portion of the head. 

Ecology. The specimens were collected in a clear water stream which topical width was about 1.5 m, depth ranged from 0.1 to 1 m and the bottom was composed of sand and small gravel. The matrix through where the stream flowed was composed of a mix of grass pasture and scarce riparian forest. Individuals were found deeply hidden among marginal vegetation and roots, mostly where the water flow was faster. Another species of the genus Gymnotus, belonging to the G. carapo species group, was found sympatrically, but not syntopically, since it was caught where the water flow was slower.

[Herpetology • 2016] How Draco Lizards Fly: A Novel Type of Wing in Animals

 formation of the composite wing during the initial phases of the gliding flight of Draco dussumieri seen from the front (left) and from below (right; corresponding photos of the same phases). The lizard jumps from the tree, reorients the body dorsoventrally and starts to spread the anterior ribs; the extended arms reach behind the back (top). The anterior ribs are further spread by the trunk musculature; the hands grasp the leading edge of the patagium and pull it forward (middle). The patagium is fully extended and controlled by the forelimbs; the glide path becomes more horizontal (bottom). White arrows indicate the positions of the hands.
Dehling, 2016.   DOI: 10.1101/086496 


Flying lizards of the genus Draco are famous for their gliding ability, using an aerofoil formed by winglike patagial membranes and supported by elongated thoracic ribs. It has remained unknown, however, how the lizards manoeuvre during flight. Here, I show that the patagium is deliberately grasped and controlled by the forelimbs while airborne. This type of composite wing is unique inasmuch as the lift-generating and the controlling units are formed independently by different parts of the body and are connected to each other only for the duration of the flight. The major advantage for the lizards is that the forelimbs keep their entire movement range and functionality for climbing and running when they are not used as the controlling unit of the wing. These findings not only shed a new light on the flight of Draco lizards but also have implications for the interpretation of gliding performance in fossil species.

[Ichthyology • 2016] Galeus corriganae • A New Species of Deepwater Catshark (Carcharhiniformes: Pentanchidae) from Papua New Guinea

Galeus corriganae 
White, Mana & Naylor, 2016


A new species of catshark, provisionally placed in the genus Galeus, is described from Papua New Guinea based on 7 specimens collected during recent deepwater surveys of the region. The new species, Galeus corriganae, is closest to G. priapus from New Caledonia and G. gracilis from northwestern Australia but differs in several morphological characters. A reclassification of the catshark groups is required to revise the familial and generic arrangement of the group.

[Botany • 2012] The Enigmatic Ginger Alpinia melichroa Rediscovered in southeast Sulawesi, Indonesia

Alpinia melichroa (K. Schum.) K. Schum.
 Alpinia sect. Botryamomum (K. Schum.) K. Schum.

Recent collections from Sulawesi allow an investigation of Amomum subgenus Botryamomum K. Schum. and its three species, Amomum chrysogynia K. Schum., Aechinosphaera K. Schum., and A. melichroum K. Schum. It is concluded that this subgenus contains a single species, Amomum melichroum K. Schum. Amomum subgenus Botryamomum and Amomum melichroum are lectotypified and Schumann's classification of them as Alpinia melichroa (K. Schum.) K. Schum. in Alpinia sect. Botryamomum (K. Schum.) K. Schum. is accepted. An amplified description including flowers and fruits is provided. Alpinia melichroa is narrowly distributed in southeastern Sulawesi; a conservation assessment is given. Sulawesi is the world's eleventh largest island with a land area greater than 180 000 km 2 . It lies in Wallacea which is the biogeographical region between Borneo and New Guinea, bounded by Wallace's line to the west and Lydekker's line to the east. Botanical exploration of Sulawesi is very far from com-plete. At the beginning of the 'Flora Malesiana' project, van Steenis (1950) estimated that only 18 herbarium specimens per 100 km 2 had been collected, a far lower number than in Peninsular Malaysia, Java, the Philippines and the Moluccas. Botanical collecting has been limited for most of the 60 years since van Steenis made his calculation and it is unlikely that the collecting density index is much higher today. This general lack of collecting effort is compounded in Zingiberaceae by other historical factors. The first significant collections from Sulawesi are those of Beccari, who visited the island in 1872–1874, leaving many valuable collections at FI. In the 1880s, Warburg made numerous collections in Sulawesi and was followed by the Sarasin cousins who made two long expeditions to Sulawesi in 1893–1896 and 1902–1903. At this period, K. M. Schumann was working on a revision of the Zingiberaceae for Engler's 'Das Pflanzenreich' (1904). Schumann worked at the Botanical Museum Berlin-Dahlem, where fire bombing in 1943 destroyed the wing of the herbarium which housed the monocotyledons. It seems that most of Warburg's and all of the Sarasins' collections were destroyed in this fire because stringent efforts by a number of experts in Zingiberaceae have located almost no surviving material.

[Fungi • 2016] Amanita castanea • A New Species and Four New Records of Amanita (Amanitaceae; Basidiomycota) from Northern Thailand

Amanita castanea  
Thongbai, Tulloss, Raspé & K.D. Hyde  

Mushrooms belonging to the genus Amanita were collected during a fungal biodiversity study in northern Thailand in 2012–2014. Morphological characteristics and molecular phylogenetic analyses were used to identify the mushrooms to species. Amanita castanea is described as new to science and compared with phenetically and phylogenetically similar species. It is assignable to Amanita stirps Citrina within Amanita series Mappae. Four other species, A. concentrica, A. rimosa, A. cf. rubromarginata and A. zangii are first reports for Thailand; detailed morphological and molecular data are provided for the Thai material.

Key words: Amanitaceae, ectomycorrhizal fungi, morphology, phylogeny

Amanita zangii Zhu L. Yang, T.H. Li & X.L. Wu, Fungal Diversity. 6: 160, 2001 (Figure 6)  

In the present study, we document a novel species and four first records of Amanita species in northern Thailand. Species circumscriptions and identification are supported by both phylogenic and morphological evidence. One interesting exception might be Amanita cf. rubromarginata. The characteristics of the Thai collections, especially the colors of the pileus, agree well with the type description. However, additional collections made in southwestern Japan indicate that the colors of aging A. rubromarginata might be more different from the Thai collections than originally thought. According to illustrations in the recent book of SE Japanese fungi (Terashima et al. 2016), the center of the cap can be nearly black and the margin, olive. These colors were never observed in the Thai material. Therefore, more collections should be made from Thailand to assess the color variation.

 Further molecular studies with multiple genes that avoid loci of the nuclear ribosomal DNA cistron and expanded taxon sampling are needed to resolve the tree topology for some Amanita sections, e.g. Amanita sect. Caesareae (Sánchez-Ramírez et al. 2014, 2015), A. sect. Validae series Mappae (Drehmel et al. 1999, Hughes et al. 2013, Tulloss & Yang 2016d), A. sect. Lepidella sensu Bas (Tulloss et al. 2016) and A. sect. Phalloideae (Cai et al. 2014, Tulloss et al. 2016). A possible set of four protein-coding loci was proposed by Sánchez-Ramírez et al. (2014) and utilized in (Sánchez-Ramírez et al. 2015).

Freyhof,  Kärst & Geiger, 2014 

Valencia robertae, new species, from the lower Pinios in northern Peloponnese and Mornos Rivers in southern mainland of Greece is distinguished from V. letourneuxi and V. hispanica by having short lateral bars or vertically elongated small blotches along the midlateral body and an almost triangular anal fin in females, prominent lateral bars between the axial blotch and the caudal-fin base and a long anal fin reaching almost or to the first caudal-fin rays in males larger than 27 mm SL. It is also distinguished by 32 fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region.

[Botany • 2016] Fordiophyton zhuangiae • A New Species (Melastomataceae) from Guangdong, China based on Morphological and Molecular Evidence

(A, B, D, E) Fordiophyton zhuangiae S. Jin Zeng & G. D. Tang  (F, I) Fordiophyton brevicaule  C. Chen 

Historically, the taxonomic study of the Asian genus Fordiophyton has had some gaps. Several specimens from Guangdong (China) have been misidentified as Fordiophyton brevicaule C. Chen. The new species proposed here shares with F. brevicaule the densely hirsute stem, rosetted leaves and glabrous hypanthia, but it is distinguished by its glabrous leaves, winged petioles, oblong petals lacking a single trichome at the apex, and purplish anthers in the longer set of stamens. The phylogenetic analyses indicate that it is a member of Fordiophyton and sister to F. brevicaule. Based on morphological and molecular data, we here recognize it as a new speciesFordiophyton zhuangiae S. Jin Zeng & G. D. Tang, which is described and illustrated.
