Abstract
Ornithuromorph birds (the clade which includes modern avian radiation) first appeared in the Early Cretaceous in Asia and achieved a great diversity during the latest ages of the Late Cretaceous (Campanian and Maastrichtian). The evolutionary history of orithuromorphs during the first 17 MYAs of the Late Cretaceous (Cenomanian to Santonian ages) remains very poorly known, as the fossil record for this time interval is largely restricted to several isolated finds of the classic avian genus Ichthyornis in North America. Here we describe an isolated distal tibiotarsus of an evolutionary advanced bird, morphologically similar to Ichthyornis, from the middle Cenomanian of Saratov Province, European Russia. This is the first documentation of an Ichthyornis-like bird in the Old World. The find further constitutes only the second pre-Campanian record of the Late Cretaceous Ornithuromorpha in Eurasia, the second record of Cenomanian birds in Russia. This discovery shows that Ichthyornis-like birds enjoyed a wide geographical distribution as early as the beginning of the Late Cretaceous. Given that the earliest and the most primitive ornithuromorph birds are known from Asia, the new find supports a Eurasian origin for Ichthyornithidae.

Conclusions
A partial tibiotarsus from the middle Cenomanian of the Nizhnyaya Bannovka locality in Saratov Province (European Russia) belongs to an evolutionary advanced ornithuromorph bird, similar in size and morphology to the North American Ichthyornis. This is the first reliable documentation of Ichthyornis-like birds in the Old World, because previously referred specimens indeed belong to Enantiornithes. This discovery confirms a wide geographic distribution of Ichthyornis-like birds already in the beginning of the Late Cretaceous and supports the Eurasian origin of Ichthyornithidae. The new specimen is further the first pre-Campanian Late Cretaceous ornithuromorph bird in Eurasian known from postcranial material.

[Ichthyology • 2017] Review and Updated Checklist of Freshwater Fishes of Iran: Taxonomy, Distribution and Conservation Status


Fig. 9: Schematic pictures of some freshwater fishes of Iran.


Abstract
This checklist aims to reviews and summarize the results of the systematic and zoogeographical research on the Iranian inland ichthyofauna that has been carried out for more than 200 years. Since the work of J.J. Heckel (1846-1849), the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of freshwater fishes of Iran based on literature and taxon occurrence data obtained from natural history and new fish collections. This article lists 288 species in 107 genera, 28 families, 22 orders and 3 classes reported from different Iranian basins. However, presence of 23 reported species in Iranian waters needs confirmation by specimens. The most diverse order is Cypriniformes (171 species, 59.40%), followed by Gobiiformes (42 species, 14.60%), Cyprinodontiformes (17 species, 5.90%), and Clupeiformes (11 species, 3.82%). Eighty-eight endemic species (30.56%) in 7 families and 26 exotic species (9.03%) in 9 families are listed here. Among 288 reported species, 163 (56.6%) species are Not Evaluated (NE), 93 (32.3%) Least Concern (LC), 11 (3.8%) Vulnerable (VU), 8 (2.8%) Data Deficient (DD), 7 (2.4%) Critically Endangered (CR), 3 (1%) Near Threatened (NT), 1 (0.3%) is Endangered (EN) and 1 (0.3%) Extinct in the Wild (EW) of the red list of IUCN. The only reason for this high number of not listed and least concern species in the IUCN Red List is lack of information about the species at national and global levels. This shows the necessity of reconsideration of global categories and application of the IUCN Red List criteria at the national level. Considering the number of endemic fishes (88, 30.56%) in Iran, the first step should be preparing an endemic national assessment for inclusion on the IUCN Red List. Over the last ten years, some native and exotic fishes have been translocated or introduced into natural water bodies. Aquaculture, sport fishing, control of malaria, ornamental purposes, research activities, demonstration in national fairs and accidental introduction are the main reasons for these introductions. Here, we report presence of the Alligator gar, Atractosteus spatula, as an introduced predatory fish from Marivan Lake which seems to have been released from an aquarium. In this checklist, additional, problematic species are also listed, the English/common name of each species is provided, the etymology of each genus is given, the conservation status of each species is given and the bibliographic list of most of published literature on the systematics of inland fishes is mentioned. The provided information will be necessary for the development of competent and pragmatic management plans and effective conservation policies.

[Herpetology • 2017] Brachycephalus darkside • The Dark Side of Pumpkin Toadlet: A New Species of Brachycephalus (Anura: Brachycephalidae) from Serra do Brigadeiro, southeastern Brazil


Brachycephalus darkside
 Guimarães, Luz, Rocha & Feio, 2017 


Abstract

Brachycephalus is a frog genus endemic to the Brazilian Atlantic Forest and characterized by the bright yellow-orange aposematic colors and the high degree of miniaturization. Herein, we describe a new species of Brachycephalus from Serra do Brigadeiro, Municipality of Ervália, Minas Gerais State, southeastern Brazil. Specimens were collected at high altitudes (i.e., 1266–1498 m above sea level) amidst the leaf litter. The new species is characterized by the presence of black connective tissue covering all dorsal muscles, body completely yellow-orange in life, presence of skull and post-cranial plates, large size (SVL of adults: 14.8–18.5 mm), bufoniform body, absence of metacarpal and metatarsal tubercles, and presence of harmonics in its advertisement call.

Keywords: Amphibia, Brachycephalus darkside sp. nov., Atlantic Rainforest, osteology, histology, bioacoustics, natural history

 Brachycephalus darkside sp. nov. female in life.

Etymology. The epithet "darkside" is a noun in apposition, derivative of the English language. It refers to the dark side of the body of Brachycephalus darkside sp. nov., which corresponds to the dark tissue surrounding the dorsal musculature, creating a dark background to the bright yellow-orange dorsum (Fig. 4). It is also a reference to the album "The Dark Side of the Moon" by the British rock band Pink Floyd.

Natural history. Specimens of Brachycephalus sp. nov. were found amidst leaf litter of “Trilha do Cruzeiro”, at the habitat Floresta Estacional Semidecidual Montana, between 1266 and 1498 m a.s.l. We observed active individuals from October to December, between 12h and 19h. Males were found calling exposed over leafs or beneath them, and females walking through the leaf litter. During the dry months (from July until September), individuals of Brachycephalus sp. nov. were found hidden deep into the layers of leaf litter, buried and within roots underground (Fig. 5). The new species is abundant in the area where it occur and reproduce syntopicaly with species of the genus Ischnocnema.

Distribution. Brachycephalus sp. nov. is known from municipalities of Ervália and Miradouro, both at Serra do Brigadeiro, north portion of Mantiqueira mountain range, Minas Gerais State, southeastern Brazil (Fig. 6). Considering the distances between locations, vegetation and altitude range (1266–1498 m a.s.l.), it is likely that this new species can be found in more locations within the Serra do Brigadeiro mountain range.

[Crustacea • 2017] New Records and Description of Two New Species of Carideans Shrimps from Bahía Santa María-La Reforma Lagoon, Gulf of California, Mexico (Caridea, Alpheidae and Processidae)


Alpheus margaritae  
Salgado-Barragán, Ayón-Parente & Zamora-Tavares, 2017 DOI: 10.3897/zookeys.671.9081 

Abstract
Two new species of the family Alpheidae: Alpheus margaritae sp. n. and Leptalpheus melendezensis sp. n. are described from Santa María-La Reforma, coastal lagoon, SE Gulf of California. Alpheus margaritae sp. n. is closely related to A. antepaenultimus and A. mazatlanicus from the Eastern Pacific and to A. chacei from the Western Atlantic, but can be differentiated from these by a combination of characters, especially the morphology of the scaphocerite and the first pereopods. Leptalpheus melendezensis sp. n. resembles L. mexicanus but can be easily differentiated because L. melendezensis sp. n. has the anterior margin of the carapace broadly rounded and has only one spine on the mesial margin of ischium in the major cheliped, versus an acute rostrum and an unarmed major cheliped. Additionally, a phylogenetic analysis was used to explore the relationships of these two new taxa. These results show that Alpheus margaritae sp. n. and Leptalpheus melendezensis sp. n. are indeed related to the species against which we are comparing them, and demonstrate that they can be considered as different species. Additional specimens of Leptalpheus cf. mexicanusAmbidexter panamensis and A. swifti are recorded for the first time in the Santa María-La Reforma coastal lagoon.

Abstract
Prior to 2012, only 158 species of Odonata were known from Angola. Surveys in 2012 and 2013 added 76 species and two further additions in 2016 brought the national total to 236 species. We provide a revised checklist with taxonomic notes and discuss the history of research, the biogeography of the fauna, and the potential for further discoveries. The national total is likely to be above 300 species. This would make Angola one of the richest countries for Odonata in Africa. The endemic species formerly classified in Chlorocypha are transferred to Platycypha.

[Ichthyology • 2017] Oxynoemacheilus hazarensis • A New Species from Lake Hazar in Turkey, with Remarks on O. euphraticus (Teleostei: Nemacheilidae)


Oxynoemacheilus hazarensis 
 Freyhof & Özuluğ, 2017 

 Abstract
Oxynoemacheilus hazarensis, new species, from Lake Hazar in the Turkish Tigris drainage, is distinguished from other Oxynoemacheilus in the Tigris drainage by having the combination of a slightly emarginate caudal fin, no suborbital groove in males, an incomplete lateral line, no scales on the back and flank in front of the anus, the maxillary barbel reaching beyond the middle of the eye, an incision in the middle of the upper lip, and the colour pattern on the flank mottled, not interrupted by an unpigmented zone along the lateral line. Oxynoemacheilus euphraticus from the Euphrates and Tigris drainages is a valid species: it is discussed and re-diagnosed against Oargyrogramma.
   
Keywords: Pisces, Freshwater biodiversity, exploration, Southeastern Anatolia


FIGURE 5. Oxynoemacheilus hazarensis, not preserved, about 65 mm SL; Turkey: North-eastern shore of Lake Hazar. 


Distribution. Oxynoemacheilus hazarensis was found in Lake Hazar, a large tectonic lake in eastern Turkey, and one of the sources of the Tigris. It may be endemic to Lake Hazar.

Etymology. The species is named for its type locality, Lake Hazar. An adjective. 

Remarks. If this is confirmed by intensive field-work in the region, O. hazarensis would be the third fish species endemic to Lake Hazar after Aphanius asquamatus (Cyprinodontidae) and Alburnus heckeli (Cyprinidae).

[Mollusca • 2017] Minaselates paradoxa • A New Genus and New Species of Epiphragmophoridae from Brazil (Gastropoda: Stylommatophora: Helicoidea)


Minaselates paradoxa
Cuezzo & Pena, 2017 


Abstract
We describe a new genus and a new species in the family Epiphragmophoridae, Minaselates paradoxa sp. n. The new species was found at the National Park Cavernas do Peruaçu, in northern portion of the state of Minas Gerais, Brazil. Minaselates paradoxa sp. n. is classified in Epiphragmophoridae based on the fact that it shares the following diagnostic features of the family: a dart apparatus with a single dart sac, and two unequal mucous glands at the terminal genitalia. Minaselates gen. n. differs from Epiphragmophora Doering, 1874 by having a granulose protoconch, shell spire with blunt apex, complex microsculpture on the teleoconch and closed umbilicus fused with the shell wall. Also, significant differences between the two genera are the presence of a long and thin kidney that extends more than half the length of the pulmonary cavity, the presence of a flagellar caecum, and a smooth jaw in Minaselates gen. n. The finding of this new species and genus is particularly significant to refine the definition of the family, since Epiphragmophoridae has been traditionally diagnosed using the same characters of Epiphragmophora. Dinotropis Pilsbry & Cockerell, 1937, the other valid genus in the family, is monospecific and is only known by the morphology of the shell. In many ways it is similar to Epiphragmophora. A cladistics analysis was made in the present study which supports Minaselates gen. n. as a different entity and as sister group of the Epiphragmophora within Epiphragmophoridae.

Clade Stylommatophora Schmidt, 1855

Superfamily Helicoidea Rafinesque, 1815
Epiphragmophoridae Hoffmann, 1928

Minaselates gen. n.

 Diagnosis: Minaselates gen. n. is distinguished by the following characters: 1) shell globose with blunt apex; 2) protoconch sculptured with granules; 3) teleoconch sculptured with complex microstructures; 4) umbilicus imperforate, parietal wall fused with columellar zone of peristome; 5) wavy spiral lines below the periphery and over ventral teleoconch surface; 6) genitalia with a dart apparatus composed by a single dart sac and two unequal mucous glands, one globose and the other oval; 7) presence of a flagellar caecum; 8) bursa copulatrix duct short, no longer than the sac.

Type species: Minaselates paradoxa sp. n. by original designation.

Description: Shell globose, with 4 to 5 convex whorls. Spire conic with blunt apex. Protoconch granulose. Teleoconch sculptured. Wavy spiral grooves at the ventral teleoconch surface. Aperture subcircular with thin peristome. Umbilicus closed. Presence of spiral brownish bands more pronounced in the body whorl. Kidney long and thin, more than half the lung roof length. Genitalia with a dart apparatus and two unequal mucous glands.

Etymology: Minaselates is a compound name formed by Minas in honor to the Brazilian state where the species was found, and selates, a noun in the genitive singular, that derives from the Greek meaning “snail” (Brown 1979).

Remarks: Minaselates gen. n. is classified in Epiphragmophoridae because it has a dart apparatus and two unequal mucous glands at the terminal genitalia. These structures are diagnostic of Epiphragmophoridae (Helicoidea) and their morphology serve to differentiate this family from the remaining helicoidean groups. Dinotropis differs from Minaselates in its depressed shell with an acute peripheral keel and open umbilicus. Minaselates differs from Epiphragmophora in its general shell shape with blunt apex, granulose protoconch and complex sculpture of the teleoconch surface. The wavy spiral grooves at the ventral teleoconch surface in Minaselates are lacking in both, Epiphragmophora and Dinotropis. The presence of a long and thin kidney in Minaselates is very different to the kidney shape in Epiphragmophora, which is triangular and shorter.


Minaselates paradoxa sp. n.

Diagnosis: Shell globular, with three spiral continuous pigmented bands, the middle, equatorial band thinner. Protoconch granulose. Dorsal side of teleoconch with axial lines bearing triangular lamellae, ventral teleoconch with wavy, concentric, spiral grooves. Imperforate umbilicus. Jaw smooth. Kidney triangular, long and thin, of about 60 to 70% the length of the lung roof. Vas deferens insertion in lower portion of flagellar caecum. Strong, short muscular penial retractor inserting at proximal epiphallus.

Etymology: The species name derives from the Greek paradoxos meaning “strangecontrary to expectation” (Brown 1979) as this is a species of Epiphragmophoridae that was not expected to occur in the state of Minas Gerais, Brazil.

Type locality: Brazil, Minas Gerais: Itacarambi, National Park Cavernas do Peruaçu, Vale dos Sonhos (523m, X = 0599645, Y = 8343426), M.S. Pena, A. Suhett, D.C. Souza leg., December 2010, (MNRJ 34.580), Holotype (ethanol preserved specimen).

Distribution: Thus far known only from National Park Cavernas do Peruaçu, northern region of Minas Gerais, Brazil.

[Botany • 2017] More New Rattans (Calamus, Arecaceae) from New Guinea and the Solomon Islands


Calamus pintaudii W.J.Baker & J.Dransf.


Abstract

As part of current research on the taxonomy of the palms (Arecaceae or Palmae) of New Guinea, ten new species of the rattan genus Calamus are described and illustrated here: Calamus baiyerensis, Calamus capillosus, Calamus erythrocarpus, Calamus heatubunii, Calamus jacobsii, Calamus katikii, Calamus kostermansii, Calamus papyraceus, Calamus pintaudii and Calamus superciliatus. An eleventh species, Calamus novae-georgii, from the neighbouring Solomon Islands is also included here. The palm flora of New Guinea now includes 62 species of Calamus, 34 of which have been described since 2002, demonstrating the remarkable scale of botanical discovery on the island. 

Key words: Calamoideae, Indonesia, lianas, Palmae, palms, Papua New Guinea, Papuasia, South-East Asia

Taxonomic treatment 

1. Calamus baiyerensis W.J.Baker & J.Dransf., sp. nov. 
Type:—PAPUA NEW GUINEA. Western Highlands Province: Baiyer River Subdistrict, Rouna River (Baiyer River valley) near Kambukom village, 1160 m, 23 July 1971, Zieck NGF 36252 (holotype CANB!, isotypes BH, LAE). 

Diagnosis:— Distinguished by the very robust, clustering habit, the sparsely armed sheath with patchy dark indumentum, the ocrea encircling the stem that disintegrates into fibres and the very robust inflorescence with robust rachillae with funnel-shaped bracts.

Etymology:— The species epithet reflects the type locality in the Baiyer River valley.  
Distribution:— Known only from the type locality in the Baiyer River valley, Western Highlands Province, Papua New Guinea.


2. Calamus capillosus W.J.Baker & J.Dransf., sp. nov. 
Type:— INDONESIA. West Papua Province: surroundings of Ayawasi, ca. 450 m, 28 July 1995, Ave 4048 (holotype L!, isotype BO). 

Diagnosis:— Distinguished by the sheaths densely armed with very fine, hair-like spines, the regularly pinnate leaves with numerous bristles on veins and margins, the very long flagelliform inflorescences, the long, unbranched peduncle, the lax primary branches, and the staminate inflorescence branched to only two orders. 

Etymology:— The species epithet refers to the very hairy appearance of the leaf sheaths, due to the abundance of fine, hair-like spines, and the numerous hair-like bristles on the leaflets.
Distribution:—Known only from the type locality near Ayawasi in the Bird’s Head Peninsula.


3. Calamus erythrocarpus W.J.Baker & J.Dransf., sp. nov.

[Fungi • 2017] Melansporella juglandiumMelansporellaceae: A Novel Family of Diaporthales (Ascomycota)


Melansporella juglandium  C.M. Tian & Z. Du


Abstract

Melansporellaceae fam. nov. is introduced to accommodate a genus of diaporthalean fungi that is a phytopathogen causing walnut canker disease in China. The family is typified by Melansporella gen. nov. It can be distinguished from other diaporthalean families based on its irregularly uniseriate ascospores, and ovoid, brown conidia with a hyaline sheath and surface structures. Phylogenetic analysis shows that Melansporella juglandium sp. nov. forms a monophyletic group within Diaporthales (MP/ML/BI=100/96/1) and is a new diaporthalean clade, based on molecular data of ITS and LSU gene regions. Thus, a new family is proposed to accommodate this taxon.
