[Crustacea • 2017] Pylopaguropsis mollymullerae • A New Species of Hermit Crab of the Genus Pylopaguropsis Alcock, 1905 (Anomura, Paguridae) from the Caribbean: “Den Commensal” or “Cleaner”?

Abstract
A new secretive, yet brightly colored hermit crab species of the family Paguridae, Pylopaguropsis mollymullerae sp. n., is fully described based on specimens from the reefs of Bonaire, Lesser Antilles, southern Caribbean Sea. Populations of this new species were discovered and photographed in the Bonaire National Marine Park under a large coral ledge, at a depth of 13.7 m, living in crevices known by scuba divers to serve as den to a pair of “flaming reef lobsters” Enoplometopus antillensis, or a “broad banded moray” Channomuraena vittata. This new species is only the second species of Pylopaguropsis Alcock, 1905 known from the western Atlantic, the 20th named worldwide, and belongs in the teevana group of species of the genus. It is remarkably similar, and herein considered geminate, to the tropical eastern Pacific congener, P. teevana (Boone, 1932), the two being characterized and uniquely different from all other species of the genus, by the striking and deeply excavated, scoop-like ventral surface of the chela of the right cheliped. Minor differences separate this new species from P. teevana in the relative length of the antennal acicles (exceeding the corneas versus not exceeding the corneas in P. teevana); dorsal armature of the right chela (smooth or with scattered minute tubercles versus with numerous small tubercles in P. teevana); surface shape of the lateral face of the dactyl of right pereopod 3 (evenly convex versus flattened in P. teevana); and coloration (red bright red stripes versus brown stripes in P. teevana). The highly visible color pattern of bright red stripes on white background typical of decapods known to have cleaning symbioses with fish, dense setation on the flagella of the antennae, and preference for a crevicular habitat, combined with brief in situ nocturnal observations, suggests the possibility that P. mollymullerae sp. n. engages in “cleaner” activities or functions as a “den commensal” with moray eels. The morphology and possible meaning of the observed behavior is discussed. A tabular summary of the distribution, habitat, and published information on all species of Pylopaguropsis is presented. Supplemental photographs and a video of live P. mollymullerae sp. n. are included.

Distribution: So far known only from the island of Bonaire, Lesser Antilles, southern Caribbean Sea; depth: 11.6–13.7 m.

Etymology: The name of this new species is given to acknowledge the efforts of the collector, photographer and environmentalist, Ms Ellen Muller, who when informed of the intended honor, preferred that the name of her granddaughter, Ms Molly Muller, be used, in hopes to inspire her to continue the tradition of protecting the amazing and fragile diversity of marine life in Bonaire.

Common name: “Candy Striped Hermit Crab”, in reference to the bright white and red striped color pattern that is similar to that of traditional candy cane.

[Arachnida • 2017] Kryptonesticus deelemanae gen. et sp. nov. (Araneae, Nesticidae), with Notes on the Mediterranean Cave Species


Kryptonesticus deelemanae 
Pavlek & Ribera, 2017 
 DOI:

Abstract

This paper describes and illustrates a new genus and a new species belonging to the family Nesticidae based on morphology and supported by molecular data. The new genusKryptonesticus gen. nov., groups eight species spread from Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. As a result, seven new combinations are proposed: K. eremita (Simon, 1879) comb. nov., K. arenstorffi (Kulczyński, 1914) comb. nov., K. fagei (Kratochvíl, 1933) comb. nov., K. beroni (Deltshev, 1977) comb. nov., K. beshkovi (Deltshev, 1979) comb. nov., K. henderickxi (Bosselaers, 1998) comb. nov. and K. dimensis (López-Pancorbo, Kunt & Ribera, 2013) comb. nov., all ex Nesticus. Kryptonesticus deelemanae gen. et sp. nov. is described on the basis of both sexes and its phylogenetic relationships with closely related species are discussed based on morphological and molecular data (the cox1, rrn and H3 genes). In addition, the species of this new genus (except for K. eremita) are clear candidates for protection: they have highly restricted ranges and some of them show a high degree of adaptation to the subterranean environment.

Kryptonesticus gen. nov.

Type species
Kryptonesticus deelemanae gen. et sp. nov. 

Etymology: The prefix “Krypto”, from Ancient Greek κρυπτός (kruptós “hidden”), alludes to the long time it took to diagnose this evolutionary line.

Distribution: From Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. All these species are known only from the type locality, or have small distribution ranges. K. eremita is an exception; this species is linked to human activities and can be found in hangars, cellars and cottages. It has been cited from France and Italy to Bulgaria and Turkey. It is a potentially invasive species, found in an abandoned air-raid tunnel in Auckland, New Zealand (Vink & Dupérré 2011).

Krypyonesticus deelemanae gen. et sp. nov.

Etymology: The specific name is a patronym in honor of Christa Laetitia Deeleman-Reinhold, an important Dutch arachnologist and a dear friend. Her work has vastly raised the knowledge of the cave spider fauna of Dinarides. The species name is in possessive genitive.

  Distribution: The new species is endemic to Croatia; it is distributed on Biokovo Mt in central Dalmatia, a coastal region in Croatia. So far it has been recorded in 20 caves scattered through the whole mountain, from the south-west sea side to the north-east continental side, from the 310 to 1640 asl (Fig. 6A). Data on all records of K. deelemanae gen. et sp. nov. are given in Appendix 2. The distribution area of K. deelemanae gen. et sp. nov. is more than 80 km away from that of K. fagei and more than 100 km from that of K. arenstorffi (Fig. 6B). 

Natural history: The type locality, Samogorska špilja, is a small cave with two entrances (Fig. 7). On the date of the last collection, 23 Jan. 2016, the air temperature in the cave was 0.5°C with cold air streaming through the cave, mostly near the cave floor. Spiders were found freely walking on the ceiling of the chamber (probably avoiding the cold air flow at the bottom) and on the side walls of the cave. The temperature in other caves where K. deelemanae gen. et sp. nov. is found ranges from 0 to 15°C. Some of those caves are very small and are greatly influenced by outside conditions (like the type locality), while the others are quite big, have a true cave microclimate and harbor diverse types of cave habitats (for example Pretnerova jama, a 254-meter deep pit). No other nesticid species are found in caves on Biokovo Mt.

[Botany • 2017] Habenaria yookuaaensis • A New Species (Orchidaceae: Orchidioideae) from Oaxaca, Mexico


Habenaria yookuaaensis 
Mejía-Marín, Espejo, López-Ferr. & R. Jiménez


Abstract

Habenaria yookuaaensis, a new species from the state of Oaxaca, is described and illustrated. The new taxon is part of the H. brevilabiataH. virensH. odontopetalaH. strictissima, and H. acalcarata complex, species with which the new entity is compared.

Keywords: Jamiltepec, Monocots, San Juan Colorado, terrestrial orchid, Mexico


 

Habenaria yookuaaensis Mejía-Marín, Espejo, López-Ferr. & R. Jiménez, sp. nov. (Figs. 1, 2)

Similar to Habenaria brevilabiata Richard & Galeotti (1845: 29), but habit terrestrial, with flowers white-greenish, petals oblong-falcate, and lip acuminate, with two triangular divaricate basal auricles.


Etymology:— The specific epithet refers to the name of San Juan Colorado, place where was found the new taxon, and derives from the Mixtec word “yo’o kua’a” formed by the terms “yo’o” (bejucos, lianas) and “kuaa’a” (rojo, colorado), and means “lugar de tierra colorada” (place of red soil). 

Distribution and Habitat:— Habenaria yookuaaensis is known until now from two localities in the state of Oaxaca. The plants are very scarce and grow between rocks, on moist soils rich in organic matter, under the shade of the trees on the riverbanks. It flowers in September.

Ankarana or Sheth’s Dwarf Lemur  |  Cheirogaleus shethi 

Frasier, Lei, McLain, Taylor, Bailey, Ginter, Nash,
Randriamampionona, Groves, Mittermeier & Louis, 2016

Abstract

A new species of dwarf lemur, Cheirogaleus shethi sp. nov., of the C. medius group is described from the dry and transitional forests of northern Madagascar. This species can be found along the forest corridor from Ankarana Special Reserve east to the Analamerana Special Reserve down to the Bekaraoka forest in the Loky-Manambato Protected Area. This species is genetically distinct from other members of the C. medius species group and is sister to a poorly known lineage in Sambava. The identification of this new species highlights the importance of northern Madagascar as a reservoir of biodiversity.

Key Words: Dwarf lemurs, primate, Strepsirrhini, taxonomy

  DOI: 10.11646/zootaxa.4221.5.1 
  
Abstract

We studied the variation in genetics, bioacustics, and morphology in Eleutherodactylus glamyrus, a regionally endemic frog species restricted to high elevations in the Sierra Maestra Massif, Western Cuba that was originally described as a cryptic species hidden under the name E. auriculatus. Genetic analysis of mtDNA sequences of the 16S and cob genes identify two allopatric and strongly supported mitochondrial clades (phylogroups) which also showed no haplotype sharing in the nuclear Rag-1 gene. Bioacustic, and morphological comparisons concordantly identify these two phylogroups as independent evolutionary lineages. Therefore, we herein restrict the name Eleutherodactylus glamyrus Estrada and Hedges to populations represented in our analyses as the western phylogroup (Cordillera del Turquino to Pico La Bayamesa) and consider specimens from the eastern phylogroup (Sierra del Cobre) to represent a new species described and named as Eleutherodactylus cattus. Our results add to the growing list of Eleutherodactylus species endemic to Cuba and highlight the importance of combining different sources of evidence for obtaining robust assessments of species limits in amphibians.

[Ichthyology • 2017] Gobiesox lanceolatus • A New Species of Clingfish (Teleostei: Gobiesocidae) from Los Frailes Submarine Canyon, Gulf of California, Mexico


Gobiesox lanceolatus 
 Hastings & Conway, 2017 

  
Abstract

Gobiesox lanceolatus is described from a single specimen collected from 300 meters depth in the Los Frailes submarine canyon in the southwestern Gulf of California. The "Canyon Clingfish" is unique within Gobiesox in having a lanceolate caudal fin, with the central rays longer than those above and below them. It is also distinguished by 14 dorsal-fin rays (first tiny and unsegmented), 11 anal-fin rays, 28 pectoral-fin rays, anus slightly closer to anal-fin origin than to posterior margin of pelvic disc, and dorsal-fin origin in front of vertical from anus. It is most similar to Gobiesox eugrammus, known from Isla Guadelupe, the coast of outer Baja California and southern California. This is the deepest record for a species of Gobiesox and only four other species of clingfishes are known from greater depths.

Keywords: Pisces, deep water, depth records, Soucoupe diving saucer


Etymology. lanceolatus, spearlike, from lancea, a short spear, in reference to the lanceolate caudal fin - the single most distinctive (and unique) feature of the species. We suggest the common name of "Canyon Clingfish" in reference to the type locality of this species.

[Botany • 2017] Athyrium haleakalae • A New Rheophytic Fern Species (Athyriaceae) from East Maui, Hawaiian Islands: with Notes on Its Distribution, Ecology, and Conservation Status


Athyrium haleakalae K.R. Wood & W.L. Wagner   


Abstract
Athyrium haleakalae K.R. Wood & W.L. Wagner (Athyriaceae), a small lithophytic fern from East Maui, Hawaiian Islands, is described and illustrated. Notes on its distribution, ecology, and conservation status are also presented. The new species appears to be an obligate rheophyte, preferring sites of fast moving water along concave walls of streams and waterfalls. Athyrium haleakalae differs from the only other known Hawaiian Athyrium, A. microphyllum (Sm.)

Abstract 
We present the first taxonomic review of the genus Phrynomedusa since its description with diagnoses of the genus and species. We present a broad literature review of the genus and provide updates and remarks about the type series, tadpoles, calls, geographic distribution, and natural history of the species of Phrynomedusa. Additionally we describe a new species from município de São Luiz do Paraitinga, state of São Paulo, Brazil. Phrynomedusa dryade was initially identified as Phrynomedusa marginata; however, an integrated analysis of morphological and molecular characters enabled its recognition as a separate new species. For the first time, the advertisement call for one species of Phrynomedusa is described in detail. We describe the tadpole and present some field notes about the activity and biology of this new species.

Phrynomedusa dryade sp. nov. 



 Etymology.— The specific epithet ‘‘dryade’’ is in the genitive case and is derived from the Ancient Greek ‘‘dryas’’ (tree) and the suffix ‘‘ades’’ (from trees). The new name is a noun in apposition. In Greek mythology, dryads were the rare guardian deities of forests and woods. The German naturalist K.F.P. Martius (Martius et al. 1840) used the term ‘Dryads’ in the first phytogeographic division of Brazilian territory into five floristic regions, in which Dryads was the term used to refer to Atlantic Coastal Forest. The name of this new species refers to the occurrence of this beautiful Monkey Frog in the Atlantic Forest Domain. 

Distribution.— Phrynomedusa dryade is known only from five localities in southeastern Brazil: four localities in state of São Paulo (municípios de Cananéia, Salesópolis, Itanhaém, and São Luiz do Paraitinga) and one locality in state of Rio de Janeiro (município de Paraty; Fig. 1).

Abstract

Bats belongs to Pteropodidae Family that spreaded evenly in Indonesia. Genus Rousettus have their morphological variances among its own species based on characteristics on each species. Among them there is fruit-feeding bats of from genus Rousettus (Chiroptera: Pteropodidae) that have many variances of morphology among its own species. This study was aimed to identify the morphological variations and its sex type influence of genus Rousettus bats from Gunung Duasudara Sanctuary, North Sulawesi. The locations were consisted 7 types of major vegetations at altitude range from 0 to 1351 m above sea level (asl). All habitat types were observed using Mist-net method at 1 and 3 m above the ground. There were found 452 individuals, including R. amplexicaudatus (224), R. celebensis (219) and R. tangkokoensis n. sp. (9). Nine individuals of Rousettus tangkokoensis n. sp. were newly found in lowland forest and coastal forest. These newly-found species were different from other Rousettus. There was discovered that sex type had influenced the skull and external body characters on R. amplexicaudatusRtangkokoensis n. sp. R. celebensis. However, most of other characters were statistically not-significant that indicated there was not any sexual dimorphism. According to the Discriminant Function Analysis (DFA), these morphological groups possess different specification. Therefore, the three species of genus Rousettus have statistically variation of skull and external body characters one to another.
