Eighteen species of cockroaches are reported to occur on the Galápagos Islands. Five species are endemic and in this paper three of these are described as new species: Chorisoneura cristobalensis Roth, C. carpenteri Roth, and Ischnoptera santacruzensis Roth. Endemic Ischnoptera snodgrasii (McNeill) COMB.NOV. is transferred from Anisopygia, and redescribed. Previous reports of the introduced species Periplaneta brunnea, Nauphoeta cinerea, and Phoetalia pallida could not be confirmed. These species may not have become established or may have become extinct. New records of native or introduced species are given for Holocompsa nitidula, Holocompsa sp., Anaplecta lateralis, Blaberus parabolicus, and Rhyparobia maderae. Of the introduced species, only Periplaneta australasiae, Symploce pallens, and Pycnoscelus surinamensis seem to have invaded native (undisturbed) habitats. The endemic species are partially or wholly flightless. This may not be a result of island life per se, but may be a specialization for life in more homogeneous litter or cave habitats at higher elevations on the islands.

Three New Species

Seven species of eukalyptorhynch flatworms from the Galapagos Islands are reported. Six of them belong to the taxon Koinocystididae Meixner, 1924, three of which are new to science. Two of these new species can be attributed to the genus Itaipusa Marcus, 1949 based on the construction of the prostate vesicle and the general structure of the female system. Itaipusa biglandula n. sp. is characterised by a very short, muscular, unarmed penis papilla, whereas I. renei n. sp. is characterised by the presence of a cirrus armed with minute scales, and two large, blunt hooks in the male atrium. The third new species cannot be placed in any existing taxon and therefore a new genus is erected: Galapagetula annikae n. gen. n. sp.. It is characterised by a straight and rather long cirrus, armed with small spines, and a clearly bipartite bursa in the female system. Additional morphological information is given for the three known species of Koinocystididae: I. divae Marcus, 1949; I. variodentata (Karling, Mack-Fira & Dörjes, 1972) Karling, 1978 and Utelga heinckei (Attems, 1897) Karling, 1954. For I. divae a new locality from Curaçao is also mentioned. The seventh species is a species of Gnathorhynchidae: Prognathorhynchus eurytuba Ax & Armonies, 1987, for which new morphological information on the organisation of the genital system is given.

Lack Of Knowledge

Thirteen centiped species and one symphylan are reported from the Galápagos Islands. Hanseniella caldaria (Hansen) is the first symphylan reported from the Galápagos Islands. Among the centipeds, Hemiscolopendra galapagosa Chamberlin is a new synonym of Scolopendra galapagoensis Bollman and should be deleted from the Galápagos list. Cormocephalus andinus Kraepelin, its probable junior synonym C. carolus Chamberlin, and Nannopodellus purpurascens Chamberlin, previously reported from the Galápagos Islands, were not in any collections made from 1974 to the present and may be extinct on the islands. Lamyctes coeculus (Brölemann), Lamyctes fulvicornis Meinert, and Newportia monticola Pocock are new records, and first appear in collections made in 1974. Two new species, Pectiniunguis krausi and Pachymerium perdrai, are described. The former had been misidentified previously as Pectiniunguis albermarlensis Chamberlin. While Pectiniunguis albemarlensis and Scolopendra galapagoensis may be Galápagos endemics, lack of knowledge about the centiped fauna of source areas precludes definitive statements.

Ant Diversity

Survey conducted on the ant diversity in the Kerala University Campus revealed a total 64 species under six subfamilies. Species belonging to the Myrmicinae dominated (51.5%) followed by Formicinae (20.6%), Ponerinae (13.2%), Dolichoderinae (4.4%), Pseudomyrmicinae (4.4%) and Dorylinae (1.5%). Endemic species Camponotus invidus Forel, 1892 , Cardiocondyla parvinoda Forel, 1902, Carebara spinata Bharti & Kumar, 2013 and Tetramorium rossi (Bolton, 1976) were recorded in the campus. Anoplolepis gracilipes (Smith, 1857), Paratrechina longicornis (Latreille, 1802), Monomorium carbonarium Smith 1858, Solenopsis geminate (Fabricius, 1804), Strumigenys membranifera Emery, 1869, Tetramorium bicarinatum (Nylander, 1846) and Hypoponera ragusai (Emery, 1894) (introduced species) were found in the campus. The results showed that the campus is rich in ant diversity. The sites with human interference showed less diversity. A potential new species in the genus Lepisiota was recorded. Trichomyrmex abberans, Carebara spinata, Crematogaster anthracina, Crematogaster biroi and Nylanderia indica are new records.

And Behavior

We recorded 502 introduced plant species during an inventory of all 2 334 private properties in Puerto Ayora, the largest town on Santa Cruz Island and the Galapagos Islands (population > 10,000) which accounts for about half of the Galapagos population. A third of these species were new records for the Galapagos Islands, 73% were found only in cultivation, 18% were naturalized and not cultivated (in Puerto Ayora), and 9% were found in cultivation and naturalized (escaped). Seventeen species previously known to occur only in cultivation in Galapagos are now considered escaped. A number of species known to be naturalized in the humid highlands of Santa Cruz do not appear to be able to reproduce in Puerto Ayora?s drier climate. To determine which introduced species should be a priority for control or eradication, the potential invasiveness of each species was assessed based on their distribution and behavior in Galapagos and elsewhere. At least 13 species were considered potentially serious invaders that could be feasible to eradicate.

Three New Species

AbstractThree new species ofDiploiciaare described from the Galapagos Islands and a fourth,D. glebosa, is transferred fromPyxine; all four are considered endemic to the archipelago. In order to accommodate these species, the generic concept ofDiploiciahas been emended. Two of the species are sterile;D. leproidicais placodioid-leproid, where the thalli derive from pseudocorticate granules aggregating into small, placodioid rosettes with distinctly lobate margins. The second sterile species,D. squamulosa, forms scattered squamules that eventually aggregate into small, placodioid rosettes. The two fertile species,D. glebosa, with an olivaceous to beige, smooth, epruinose upper surface, andD. neotropica, with a white to grey-white, roughened, pruinose upper surface, form larger thalli typical ofDiploicia, have apothecia that are initially lecideine, but are soon engulfed and hidden by a thick thalline margin. Anatomically the proper exciple remains visible for a considerable part of the ontogeny, although it eventually becomes almost completely reduced to a few pigmented or almost hyaline hyphae. This transition from lecideine to lecanorine apothecia is similar to thephysciaeformis-type ontogeny observed in somePyxinespecies. Several species currently accommodated inBuellias. lat. with diploicin and effigurate thalli that lack distinctly lobate margins are discussed and the Socotran endemicPhyscia endopyxineais transferred intoDiploicia.

We studied a variety of chthoniid pseudoscorpions collected from the semiarid zone of Western Australia. Five new species of Tyrannochthonius Chamberlin, 1929 and three new species of Lagynochthonius Beier, 1951 are named and described from the Pilbara and Gasgoyne regions, and surrounding areas such as Barrow Island. Tyrannochthonius basme, sp. nov. and Lagynochthonius asema, sp. nov. from pisolitic mesas near Pannawonica, T. garthhumphreysi, sp. nov. from limestone karst on Barrow Island, T. souchomalus, sp. nov. from calcrete deposits near Cue, T. billhumphreysi, sp. nov. and L. polydentatus, sp. nov. from a calcrete deposit on Sturt Meadows Station and L. leemouldi, sp. nov. from calcrete near Marble Bar are all considered to represent hypogean species as all exhibit typical troglomorphic adaptations including total loss of eyes and attenuated appendages. New records are provided for T. brooksi Harvey and T. butleri Harvey from Cape Range peninsula. A new epigean species, T. aridus, sp. nov., was found on Barrow Island and the Pilbara mainland. Two further putative new species based upon nymphal specimens from subterranean environments are described but not named owing to the lack of adult specimens. Although the epigean species T. aridus, sp. nov. is relatively widespread, all of the subterranean species are thought to represent short-range endemic species as they have been found at very few locations, all of which occur in localised habitats such as limestone or within mesa formations. Tyrannochthonius chamorro Chamberlin, 1947 from Guam is transferred to the genus Lagynochthonius, creating the new combination Lagynochthonius chamorro (Chamberlin 1947).

First Time

AbstractThirteen species of Chloropidae are recorded from the Galápagos Islands, Ecuador. Seven new species are described: Diplotoxa loma sp. n. (subfamily Chloropinae); Conioscinella empheria sp. n.; Gaurax gethosyne sp. n.; Hippelates alyscus sp. n.; Liohippelates baptipalpis sp. n.; Olcella anaclasta sp. n.; Olcella lupina sp. n. (subfamily Oscinellinae). Another species in the genus Apallates is apparently undescribed, but there is insufficient information to justify a formal description. Monochaetoscinella anonyma is recorded for the first time from the archipelago. Four species previously recorded from the archipelago were also identified: Cadrema pallida; Conioscinella galapagensis; Elachiptera cultrata; Liohippelates galapagensis. Previously published Galápagos records of Liohippelates pusio apparently refer to L. galapagensis. A key to the Galápagos species of Chloropidae is given. Geographic affinities of the Galápagos chloropid fauna are similar to those of other Diptera from the archipelago, with few pantropical species, some species also found in the northern Neotropical and southern Nearctic regions, and endemic species apparently with Neotropical sister groups.

Gulf Of Tehuantepec

In the Tropical Eastern Pacific region, the gammaridean amphipods of the families Maeridae and Melitidae are represented by 28 species and 11 genera; the genus Elasmopus is the richest, with 13 species. The examination of approximately 3,250 specimens resulted in 12 new records from the Gulf of Tehuantepec, belonging to four genera, Elasmopus, Maera, Quadrimaera and Melita. All species are illustrated and described. Seven new species are described as: Elasmopus bastidai n. sp., Elasmopus karlae n. sp., Elasmopus lecroyae n. sp., Elasmopus marcelae n. sp., Elasmopus oaxaquensis n. sp., Maera umarae n. sp., and Melita bousfieldi n. sp. With these new species the genus Elasmopus from the Tropical Eastern Pacific is increased to 18 species that corroborates the hypothesis of Barnard (1979) “on the Pacific there are (sic) a mark of speciation of genus Elasmopus”. In addition, there are five new records from the Gulf of Tehuantepec: three species of Elasmopus and two of Quadrimaera. Also, the range distribution of Elasmopus temori Barnard and E. zoanthidea Barnard, is increased to the north from the Galapagos Islands to the Gulf of Tehuantepec; for E. tubar Barnard, Quadrimaera chinarra Barnard, and Q. reishi Barnard, there are new intermediate records between the Gulf of California and the Galapagos Islands. With the exception of the species of Quadrimaera, all known species represent the second record in the region after their first descriptions.
