The genera and species in six families of the eugregarine suborder Aseptatorina Chakravarty, 1960, are reviewed and the presently accepted ones are listed: Aikinetocystidae Bhatia, 1930 (two genera and two species); Diplocystidae Bhatia, 1930 (one genus and eight species); Allantocystidae tocystidae Bhatia, 1930 (one genus and one species); Schaudinnellidae Poche, 1913 (one genus and one species); Ganymedidae Huxley, 1910 (one genus and one species); and Enterocystidae Codreanu, 1940 (one genus and eight species). A list of 22 synonyms and lapsi calami is also given. Species which might be of value in the biological control of disease vectors are indicated.     

Morphometric study of the genus Panstrongylus Berg, 1879 (Hemiptera, Reduviidae, Triatominae)

The subfamily Triatominae is actually represented by 137 species distributed among 6 tribes and 19 genera. Within this subfamily, the genus Panstrongylus, Berg 1879, is composed by 13 species widespread in sylvatic, peridomestic, and domestic habitats of Neotropical regions. These species are vectors of Chagas disease and consequently are found associated with its main hosts, such as birds and mammals. Interest in species of this genus has been increasing in the last few years. Reports of several authors indicate these Triatominae to invade and colonize houses, increasing their epidemiological significance. Morphometry was used in this study to investigate correlations among possible closely related species. We measured 224 specimens among 13 species through a set of metric variables of the head. The results indicated that the genus Panstrongylus seems to be homogeneous since 10 of the 14 species were shown to be closely related.     

A revision of the genus Eutobrilus Tsalolikhin, 1981 (Nematoda, Triplonchida)

A revision of the genus Eutobrilus Tsalolikhin, 1981 is made on the basis of the author’s and literature data. The diagnosis of the genus has been partially changed. Species diagnostic characteristics have been analyzed, and the species inventory has been made. Fifteen valid species have been included into the genus. A key to the valid species is presented.     

A record of the Plain Tiger,Danaus chrysippus,in Turkey

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.     

A revision of the genus Camptocercus (Anomopoda, Chydoridae, Aloninae)

The genus Camptocercus is revised. Camptocercus streletskayae sp. n. is described from East Siberia. The status of other species is discussed on the basis of a standard set of morphological features, including the structure of the cephalic region, the post-abdomen and post-abdominal claw, the dorsal keel, denticles at the ventro-posterior angle of valve, and setae on the inner distal lobe of limb I. Geographical distribution of species of this genus is discussed. A key to the species of this genus is composed. This revised version was published online in July 2006 with corrections to the Cover Date.

The Oriental and East Palaearctic genus Hartemita Cameron, 1910 (Braconidae: Cardiochilinae) is recorded for the first time from Vietnam. Sixteen species of the genus Hartemita are currently recognized from Oriental and East Palaearctic regions. One species is newly recorded for Vietnam, Hartemita singaporensis (Mao, 1945)and six new species from Vietnam are described and illustrated: Hartemita coffeanasp. n., Hartemita daklakasp. n., Hartemita khuatbaolinhaesp. n., Hartemita similissp. n., Hartemita maculatasp. n. and Hartemita vietnamicasp. n. A key to species of the genus Hartemita Cameron is included.     

Observations on the remarkable disrupted geographical distribution of the genus Microbuthus Kraepelin, 1898 in North Africa, with the description of a new species from Egypt (Scorpiones, Buthidae)

A disrupted Perisaharan pattern of distribution is confirmed for the species of the genus Microbuthus Kraepelin, 1898. A new species, Microbuthus flavorufus sp. n., is described from Egypt, raising the total number of known species of the genus to five.     

Discovery of the genus Meggoleus Townes, 1971 (Hymenoptera, Ichneumonidae, Tersilochinae) in Peru, with the description of two new species

The genus Meggoleus Townes, 1971 (Ichneumonidae, Tersilochinae) currently comprises two species, one from Brazil and one from Gabon. The genus is recorded from Peru for the first time, with a range extension of the type species, Meggoleus spirator Townes, 1971, and the discovery of two new species - Meggoleus fuscatussp. n. and Meggoleus pampahermosensissp. n. A key to the world's species is provided.     

Phylogenetic reconsideration of Myrmekiaphila systematics with a description of the new trapdoor spider species Myrmekiaphila tigris (Araneae, Mygalomorphae, Cyrtaucheniidae, Euctenizinae) from Auburn, Alabama

The trapdoor spider genus Myrmekiaphila currently comprises 11 nominal species. A recent molecular phylogenetic evaluation of the group identified a number of problems with respect to how species and species groups were delineated by Bond and Platnick in their 2007 taxonomic revision of the genus. We report herein the discovery of a new species, Myrmekiaphila tigrissp. n. The phylogenetic position of the species is evaluated using a molecular phylogenetic approach based on a set of mtDNA markers. Our preferred phylogenetic hypothesis supports the recognition of a new species and further highlights the need to more carefully investigate species boundaries within the genus. These results further indicate that palpal bulb morphology is rapidly evolving and has likely been a contributing factor in rendering a number of species paraphyletic with respect to the molecular data.     

Molecular ecology, speciation, and evolution of the reef fish genus Anisotremus

Grunts (family Haemulidae) in the genus Anisotremus comprise 10 described species which occur predominantly on coral reefs and subtropical rocky reefs in the Neotropics of the Tropical Eastern Pacific the Caribbean and adjacent waters. In this study, the phylogenetic relationships for all described species were examined based on one mitochondrial gene (cytochrome b) and one nuclear marker (the first intron of the ribosomal protein S7). Closely related species of the genus Haemulon and the single representative of the genus Genyatremus, G. luteus were also included in the analysis, following the suggestion, based on morphological data, that they may be closely related to, or possibly placed within, Anisotremus. Two sweetlips, genus Plectorhinchus, which belong to the recognized sister subfamily Plectorhynchinae, were used as outgroups. Two species pairs in the ingroup genus Anisotremus are geminate species, which presumably diverged after the rise of the Isthmus of Panama, thus providing an internal molecular clock calibration. This allowed for a comprehensive evolutionary scenario for the genus. Our data were consistent with two independent allopatric speciation events (geminate species), and one likely sympatric speciation event. Our data were also consistent with the placement of Genyatremus and Haemulon within the genus Anisotremus, thus breaking its monophyletic status. As proposed for other coral reef species, Anisotremus seems to have colonized coral reefs from non-coral reef habitats. In addition, ancestral species seem to have been widespread, since species that are currently found in Brazilian and Pacific waters are basal on the phylogenetic tree. Finally, this study adds to the hypothesis of a secondary evolutionary center in the New World.     

A new species of Ocydromia Meigen from China,with a key to species from the Palaearctic and Oriental Regions (Diptera,Empidoidea, Ocydromiinae)

Previously only one species of the genus Ocydromia Meigen was recorded from China. Here a second species of the genus from China, Ocydromia shanxiensis sp. n., is reported. A key to the species of the genus from the Palaearctic and Oriental regions is presented.     

Phylogeny and biogeography of the genus Pseudectinosoma, and description of P. janineae sp. n. (Crustacea, Copepoda, Ectinosomatidae)

Recent stygobiological investigations carried out in the circum-Mediterranean area resulted in the discovery of a new species of the genus Pseudectinosoma Kunz, described herein as P. janineae sp. n. The taxonomic status of the genus is reviewed in a phylogenetic perspective. The origin of the present-day distribution of the genus Pseudectinosoma is reconstructed both from patterns of relationships among the species and from palaeogeographical data.     

Revision of the genus Miridiba Reitter, 1901 (Coleoptera, Scarabaeidae, Melolonthinae)

The genus Miridiba is here reviewed on the basis of external morphological and genital characters. This genus now contains 27 species, eight of which are new transfers from Holotrichia Hope, 1837; Holotrichia (Pledina) ; Melolontha Fabricius, 1775; and Neodontocnema . A type series of thirteen species is designed. Hippotrichia and Neodontocnema are described in detail.     

Biogeographic hypothesis explaining the diversity of the genus Amphimallon Berthold, 1827, in the Mediterranean Basin (Coleoptera,Scarabaeidae, Melolonthinae,Rhizotrogini)

In this paper, the analysis of the current distribution of species, or species-groups, of the Western–Palaearctic genus Amphimallon Berthold, 1827, based on a phylogenetic hypothesis recently provided and relevant paleogeographical events that occurred in the Mediterranean Basin from Late Paleogene (35 Myr BP) to the present, supports a biogeographical scenario to explain species diversity within this genus. The center of origin of this genus is hypothesized to be in the Iberian Peninsula. Microplate fragments drifting from the Iberian Peninsula, successive landmass suture events between the Eastern and Western Mediterranean Basins, separation of Tethys and Paratethys Oceans, re-establishment of marine connections, uplift of the Alps, and drying out of the Mediterranean are hypothesized as the principal events allowing dispersal of populations throughout Mediterranean Basin and biogeographical vicariances within the genus Amphimallon.     

Description of a new species of the genus Hungarocypris Vavra, 1906 (Crustacea : Ostracoda) from Sulawesi,Indonesia, with a discussion on the distribution of the genus

A new species of the genus Hungarocypris Varvra, 1906 is described from Sulawesi, Indonesia. This is the third known living species for the genus. At present four extinct and three extant species are known for Hungarocypris and a discussion is given on its global distribution.     

Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

New Fabriciola species (Polychaeta, Sabellidae, Fabriciinae) from the eastern Atlantic, with a description of sperm and spermathecal ultrastructure

New species in the genus Fabriciola Friedrich are described. Fabriciola is defined by a single synapomorphy, the presence of non-vascularized, ventral filamentous appendages. Otherwise the genus is variable, with differences among species in chaetae, eyes, and peristomial organization. The new species, Fabriciola flammula, F. liguronis and F. parvus , reflect this heterogeneity. Fabriciola liguronis has spermathecae in the radiolar crown of females, the first record of these structures in Fabriciola , but F. flammula and F. parvus lack spermathecae. Sperm ultrastructure in all three species share apomorphies with other fabriciins, but vary in other respects. Fabriciola may be paraphyletic, but material of the type species F. spongicola (Southern, 1921) has been unobtainable so far, and detailed study of this species is required to define the genus Fabriciola adequately.     

Extreme gender flexibility: using a phylogenetic framework to infer the evolution of variation in sex allocation, phylogeography, and speciation in a genus of bidirectional sex changing fishes(Lythrypnus, Gobiidae)

The genus Lythrypnus is a group of marine gobies that exhibit extreme gender flexibility as bidirectional sex changers. The genus consists of 20 described species and several undescribed species that are distributed in the Americas. Five species have been characterized with respect to sex allocation and gonad morphology. The hormonal, morphological, and behavioral aspects of sex change have been studied extensively for one species, L. dalli. These data, however, have not been interpreted in an evolutionary context because a phylogenetic hypothesis has not previously been proposed for the genus Lythrypnus. We propose the first phylogenetic hypothesis for the genus based on molecular data from three mitochondrial genes (12s, ND2, and Cytb), one nuclear gene (Rag1) and one nuclear intron (S7). We also include three previously undescribed Lythrypnus species. Our results support the monophyly of the genus with L. heterochroma, an Atlantic species, as the basal taxon. After the divergence of L. heterochroma, there are two main clades, one comprised of species distributed in the Atlantic, the other comprised of species distributed in the Pacific. These data indicate an Atlantic origin for the genus, followed by divergence after the closure of the Isthmus of Panama. Our data also support the monophyly of three previously described species complexes, the L. rhizophora complex and L. dalli complex in the Pacific, and the L. mowbrayi complex in the Atlantic. We mapped patterns of sex allocation within this genus onto the fully resolved and supported topology, and found that sexual plasticity and gender flexibility is likely a synapomorphy for the genus. Overall our results create a well-supported framework to understand the phylogeography of the genus, and to interpret the evolution of sex allocation in Lythrypnus gobies.     

Two new genera, Crassoseta and Brachysternopsis, of the family Diplogyniidae (Acari, Mesostigmata, Trigynaspida)

The genus Crassoseta is erected for three new species of diplogyniid mites taken from passalid beetles collected in Mexico, Brazil and Costa Rica; Brachysternum cornutum Hyatt, 1964 is transferred to this genus and a key to species is given. Brachysternopsk gen.n. is established for B. flechtmanni gen. et sp.n. taken from an ant, Atrica capiguara. in Brazil.     

At the lower size limit for tetrapods, two new species of the miniaturized frog genus Paedophryne (Anura, Microhylidae)

I describe two new species in the miniaturized microhylid frog genus Paedophryne from forests in southeastern Papua New Guinea. The first species is described on the basis of two specimens and exhibits female snout-vent length of 8.5-9.0 mm (no males known), whereas that of the second species, described on the basis of 12 specimens, is 8.8-9.3 mm, with males 8.1-8.9 mm. These frogs are smaller than the other two diminutive species described when the genus was recently erected, and they represent what are currently the smallest known species of tetrapods. The two species replace each other elevationally on the same mountain massif and occur in relative geographic proximity to the other named species of the genus. Females of both species contain only two enlarged ova, suggesting that they also possess clutch sizes at the extreme lower end of variation in frogs. All species of Paedophryne inhabit leaf litter, as seen for most other miniaturized anurans.
