A cavernicolous planthopper in the Galápagos Islands (Homoptera: Auchenorrhyncha: Cixiidae)

A new troglobitic cixiid species, Oliarus hernandezi sp. n. is described from three lava tubes on the island of Floreana, Galápagos group. It is the first known obligately cavernicolous planthopper species from Galápagos. Notes on its ecology and distribution are given, and phylogenetic relationships to epigean Oliarus species from Galápagos are discussed.     

New troglobitic species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from caves in northern Italy and Austria,with a key to adult species of the genus

Three new troglobitic species of rhagidiid mites of the genus Troglocheles – two from northern Italy, Troglocheles quinquesolenidiata sp. nov. and T. lanai sp. nov., and T. christiani sp. nov. from Austria – are described. A key to adults of the known species of the genus Troglocheles Zacharda of the world is given. In these vicariant species the different apomorphic morphological traits, troglomorphisms, are discussed in aspects of allopatric speciation, climatic relict hypothesis and evolutionary processes of adaptation to specific niches and time of occupation of the subterranean habitat. All new taxa are authored by M. Zacharda only.     

A redescription of the genus Cyrebion Fairmaire, 1891, with notes on related taxa and distribution (Coleoptera: Cantharidae)

Eight new species and one new record of Elasmopus Costa, 1853 are described from Australian waters including the extended offshore territories of Cocos (Keeling) Islands (Indian Ocean), Christmas Island (Indian Ocean), Ashmore Reef (Timor Sea), Norfolk Island (Tasman Sea) and Lord Howe Island (Tasman Sea). Range extensions are reported for seven described Australian species. Twenty-three species are now known from Australian waters. Elasmopus arafura sp. nov., E. carteri sp. nov., E. hyperopia sp. nov., E. leveque sp. nov., E. mcluerensis sp. nov., E. otus sp. nov., E. shepherdi sp. nov. and E. woodjonesi sp. nov. are described herein.     

A new troglobitic meenoplid from a lava tube in Western Samoa (Homoptera Fulgoroidea Meenoplidae)

Recent investigations in lava tubes on Savai'i, Western Samoa, have revealed the existence of a new cave-dwelling meenoplid species, Suva oloimoa sp. nov., from the deep cave zone. Troglomorphies displayed by S. oloimoa sp. nov. include reduction of ocelli, compound eyes, pigmentation and, to a lesser degree, of tegmina and wings. Due to these features and to its ecology, the species is regarded as an obligate cavernicole (troglobite). This is the first record of a troglobitic meenoplid in the Pacific.     

Species of the genera Bakera and Mangganeura (Homoptera: Auchenorrhyncha: Typhlocybinae) occurring on mango and other crop plants in the Oriental region

The genera Bakera (Bakera), Bakera (Guinobata) and Mangganeura (Homoptera: Auchenorrhyncha: Typhlocybinae) are re-described and compared. Sandalla is considered a synonym of Bakera (Guinobata) (syn. nov.).

Bakera (Bakera) nigrobilineata (Melichar) (=vittata Mahmood) is redescribed and illustrated from mango in the Philippines, on which it is frequently abundant, and found in association with Bakera (Bakera) luzonica sp. nov. which is described. Bakera (Bakera) abaca sp. nov. is described from the Philippines having been collected on abaca (Manila hemp). Bakera (Guinobata) nigroscuta Mahmood is redescribed from the Philippines and its association with coconut confirmed. Mangganeura reticulata Ghauri, described from Malaysia on mango, has been found in Thailand and the hitherto unknown female is described.     

The scolopendromorph centipedes of St John,U.S. Virgin Islands collected by Dr W. B. Muchmore

A collection of scolopendromorph centipedes from the U.S. Virgin Islands is described. It comprises five species Scolopendra alternans, Cormocephalus impulsus sp. nov., Otostigmus (Parotostigmus) caraibicus, Newportia longitarsis virginensis subsp. nov., and Cryptops neocaledonicus muchmorei subsp. nov.     

Three new endogean species of Laparocerus Schönherr, 1834 from the Canary Islands (Coleoptera,Curculionidae)

Three new species of the weevil genus Laparocerus Schönherr (1834) adapted to the edaphic environment of the Canary Islands are described: L. edaphicus n. sp., L. oromii n. sp. and L. lopezi n. sp. They live in the humid laurel forests of Tenerife (Anaga Mountains), La Gomera (Garajonay National Park) and Gran Canaria (Valsendero), respectively. The small size and somewhat tubular body shape is a common character among them, as is the reduction of the eyes, which are totally absent in L. oromii n. sp. Despite these common adaptive traits, the three species seem not to be directly related. A key for the identification of all the known cryptozoic (edaphic and troglobitic) species of Laparocerus is provided.     

Freshwater Ostracoda of the subfamily Cyprinotinae from Punjab,India, with the description of eight new species

Summary

Eleven species belonging to subfamily Cyprinotinae are described and illustrated from Punjab, India.

Four new species of Mesomyzostoma (Myzostomida: Annelida)

Mesomyzostoma Remscheid, 1918 currently includes three described species that live in the coelom and/or gonads of comatulid crinoids: Mesomyzostoma reichenspergeri Remscheid, 1918, Mesomyzostoma katoi Okada, 1933 and Mesomyzostoma lanterbecqae Summers and Rouse, 2014 in Summers, Al-Hakim et al. 2014. Here we describe four new species of Mesomyzostoma and assess their phylogenetic relationships using 18S rRNA, cytochrome oxidase subunit I and 16S rRNA sequence data. We also designate a neotype for M. katoi as the original types appear to be lost. We record M. reichenspergeri from the Australian Great Barrier Reef and from northern Papua New Guinea, but samples from the type locality (Aru Islands, Indonesia) and previously recorded host are needed for confirmation. The new species of Mesomyzostoma are one Japanese species: Mesomyzostoma okadai sp. nov., and three Australian species: Mesomyzostoma lobus sp. nov., Mesomyzostoma leukos sp. nov. and Mesomyzostoma botulus sp. nov. The first infects the coelom of crinoid arms and pinnules, and the other three are found in crinoid oral discs. We also record M. leukos sp. nov. and M. botulus sp. nov. from Papua New Guinea. Phylogenetic analyses suggest that M. okadai sp. nov. is the sister group to all other Mesomyzostoma.     

Pontoniine shrimps from the Zoological Museum,Copenhagen

The braconid parasitoids (Hymenoptera: Braconidae) associated with seeds of Dipterocarpaceae in Malaysia

Nineteen species of Braconidae have been reared from seeds of Dipterocarpaceae (mainly Shorea species) in West Malaysia. Eleven new species (Brachistinae: Schizoprymnus mesocaudus sp. nov.; Schizoprymnus torreadoroides sp. nov.; Braconinae: Bracon nitidisoma sp. nov.; Bracon rugulifer sp. nov.; Syntomernus shoreatus sp. nov.; Spermatobracon triangulornatus sp. nov.; Cheloninae: Ascogaster cornifera sp. nov.; Ascogaster lamellifera sp. nov.; Phanerotoma divergens sp. nov.; Microgastrinae: Apanteles hemiaurantius sp. nov.; Apanteles striatus sp. nov.) and one new genus (Spermatobracon gen. nov.; type species: Spermatobracon triangulornatus gen. nov. and sp. nov.) are described and illustrated.     

Two new species of protandric pheretimoid earthworms belonging to the genus Metaphire (Megascolecidae: Oligochaeta) from Taiwan

This paper describes two new species, each consisting of two subspecies, of protandric, octothecal pheretimoid earthworms from Taiwan. They are Metaphire paiwanna sp. nov. typica, Metaphire paiwanna var. liliumfordiI subsp. nov., Metaphire bununa sp. nov. typica and Metaphire bununa var. glareosus subsp. nov. The var. typica of both new species occurred on the west side of the Central Mountain Range, whereas the subspecies, liliumfordi and glareosus, occurred on the east side of the range. Apparently, the Central Mountain Range constitutes a geographical barrier for isolation and subspeciation. Metaphire paiwanna has a male disc medial to male pore (opening of copulatory pouch) with a horizontal ridge, the character shared by holandric and sexthecal Amynthas swanus (Tsai) of Taiwan and Metaphire aggera (Kobayashi) of Korea and Manchuria, whereas M. bununa resembles more closely holandric, octothecal Metaphire riukiuensis (Ohfuchi) of the Riukiu Islands than protandric, octothecal Metaphire stephensoni (Michaelsen) of Indochina.     

An unusual new species of Trechona (Araneae: Mygalomorphae: Dipluridae), from quartzitic caves of the Diamantina Plateau,Minas Gerais,Brazil, with a key to the known species

Trechona diamantina sp. nov. is described from quartzite caves in Diamantina, central Minas Gerais State, Brazil. This represents the largest cavernicolous mygalomorph population ever recorded. The new species is the first Trechona recorded from a xeric habitat, namely the Rocky Fields on the Diamantina Plateau. T. diamantina sp. nov. is closely related to T. uniformis, both species possessing elongated male and female copulatory organs and both constructing distinct funnel-webs and sheet-webs in quartzite formations. T. diamantina sp. nov. is distinct in possessing less elongated embolus and receptacula seminis. A key for all valid species of the genus is given.

Two new amphipod crustaceans of the genus Bahadzia from ‘blue holes’ in the Bahamas and some remarks on the origin of the insular stygofaunas of the Atlantic

Bahadzia setimana sp. nov. from South Andros, and B. obliqua sp. nov. from Cat Island, both in the Bahamas, are described. The recently described genus Bahadzia now contains five closely related taxa, each apparently confined to a single island or isolated group of islands, in a restricted area of the West Indies, ranging from Haiti in the south to the northern Bahamas.

The present discoveries show not only that low-salinity groundwaters of the West Indies have a marked degree of insular endemism, but that the high-salinity anchihaline habitats possess endemics in certain groups as well.

Current models which seek to explain the evolution of stygobionts on Atlantic Islands are reviewed critically and the most likely synthesis is provided.

New and little-known genera of cheilostome Bryozoa from the New Zealand region

The diagnostic characters of the cavernicolous genus Spelaeoblatta Bolívar, 1897, previously known only from a female, are given based on the male of S. thamfaranga n. sp. from Thailand. Nocticola adebratti n. sp. from Sabah is described.     

Two new species of the commensal shrimp genus Periclimenaeus Borradaile, 1915, (Decapoda,Palaemonidae) from the Maldive Islands

Two new species of the commensal shrimp genus Periclimenaeus Borradaile, found in the waters of the Maldive Islands, Indian Ocean, are described and illustrated. P. tchesunovi sp. nov. is related to P. rastrifer Bruce. The former may be distinguished by its deeper rostrum, with dentition 6/1, the presence of supraorbital tubercles, and broad, spatulate fingers on the first pereiopods. P. zarenkovi sp. nov. closely resembles P. diplosomatis Bruce in the presence of minute denticulations on the dactylar cutting edge of the major second pereiopod, but differs from it by a deeper rostrum with 5 dorsal teeth, more robust chelae of the second pereiopods, and small dorsal telson spines.
