A new species of Liolaemus is described from southwest of the town of Añelo, Neuquén Province, Argentina. Integrative evidence methodology of external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (cyt-b) is used to place the new species to the species group of Liolaemus boulengeri. The new species is phenotypically close to L. mapuche. The new Liolaemus is medium to large in size (males 77.64–83.98 mm, females 72.88–78.58 mm), with evident sexual dichromatism. Genetic distances of the mtDNA (cyt-b) between the new species and its closest relative species are greater than 3% (L. cuyanus 7.48–12.02%; L. josei 7.56–9.60%; L. puelche 8.23–9.93%; L. mapuche 8.51–9.79%). Molecular and morphological phylogenetic results show L. mapuche as the sister species of the new one. The new species is larger than L. mapuche. Dorsal and ventral scales are more numerous in the new species than in L. mapuche, precloacal pores in females are present in L. mapuche and absent in the new species. It has strict psammophilic habits, using sand mounds and sheltering, under Alpataco (Neltuma alpataco) bushes. The L. boulengeri group now contains 75 species distributed in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay.

Aus Nistkästen wurden nach dem Ausfliegen der Vögel etwa
500 Nester entnommen und die darin vorhandenen Insekten
herausgesucht oder mit einem Eklektor abgesammelt. Die gefundenen
Arten lassen sich den in Nestern bekannten Gilden
zuordnen: Parasiten, Saprophage, Räuber oder Parasitoide
(Schlupfwespen i.w.S. und Raupenfliegen). Für die cyclorrhaphen
Dipteren und ihre Parasitoide wird ein Nahrungsnetz als
Bild eines Teils der Choriozönose im Vogelnest dargestellt. Es
konnten 32 Arten in 10 Familien gefunden werden. Nidikol
sind die Vogelblutfliegen (Protocalliphora azurea, Calliphoridae)
mit ihrem Parasitoiden (Nasonia vitripennis, Pteromalidae), der
durchschnittlich 40% der Puparien abtötet und dadurch für die
Vögel eine besondere Bedeutung hat. Eine zweite Vogelblutfliegenart
(P. falcozi) konnte nur in Süddeutschland gefunden
werden. Bei dieser Art ist der größte Teil der Puparien mit einer
Hülle aus Nistmaterial vor der Parasitierung geschützt. Die
wenigen nicht geschützten Puparien werden ähnlich häufig
parasitiert wie die von P. azurea. Zwei weitere Parasitoide (Dibrachys
cavus und D. lignicola, Pteromalidae) konnten in Puparien
von Raupenfliegen (Triarthria setipennis und Ocytata
pallipes, Tachinidae) gefunden werden, die ihrerseits als Parasitoide
in Ohrwürmern (Forficula auricularia, Forficulidae)
leben. Die Arten der Nahrungskette Ohrwurm → Raupenfliege
→ Dibrachys gehören zu einer anderen Choriozönose, die sich
in Verstecken bildet und sich im Nistkasten mit der der Nester
überschneidet. Bei den Flöhen (Ceratophyllus gallinae, Ceratophyllidae)
konnte das Verlassen des Nestes nach dem Ausfliegen
der Jungvögel bis zur folgenden Brutsaison mit einem Eklektor
ermittelt werden. Im Herbst erscheinen zunächst die im Nest
vorhandenen adulten Flöhe, im folgenden Frühjahr die Individuen
der neuen Generation.
Die in Nistkästen gefundenen saprophagen Insekten werden
erstaunlich wenig parasitiert. Sie fressen Mikroorganismen
und sind am Abbau des Nistmaterials beteiligt. In Nistkästen
spielen sie allerdings eine untergeordnete Rolle, weil das Nistmaterial
normalerweise entfernt wird. Es wird diskutiert, dass
sie in natürlichen Höhlen eine Bedeutung beim Abbau des
Nistmaterials haben. Die Wirkung der Keratin fressenden
Arten, die Haare und Federn abbauen, wird an Hand von
Fängen der Kleistermotte (Endrosis sarcitrella, Oecophoridae)
gezeigt.
The nesting biology of the potter wasp Pachymenes ghilianii (Spinola) (Hymenoptera: Vespidae: Eumeninae) is described based on observations made in the Cerro Turega Hydric Reserve, Penonome, Panama. The collection of building material, the architecture of the nest, the process of building a cell and cell provision with geometrid larvae (Lepidoptera: Geometridae), and the emergence time of the adults are recorded.
Paratelenomus saccharalis (Dodd) (Hymenoptera: Scelionidae) parasitizing Brachyplatys subaeneus (Westwood) eggs is reported for the first time for Panama. Brachyplatys subaeneus is an invasive species from Asia and is regarded as an important agricultural pest in the Americas.

The stinkbug Edessa leucogramma (Perty) (Hemiptera: Pentatomidae: Edessinae) is reported as a pest of young yellow guayacán trees (Handroanthus chrysanthus (Jacq.) S.O. Grose, Bignoniaceae) in the metropolitan area of the Aburra Valley in Antioquia, Colombia (AMVA). We provide a short description of the adult and immature stages and report for the first-time protozoa associated with the digestive system of this species of true bug in addition to information regarding a fungus found associated with Edessa leucogramma in the field.

Within Nearctic Cicindelidae, Cicindelini, Eunota togata (LaFerté-Sénectère, 1841) (Coleoptera: Cicindelidae) exists as several distinct phenotypes, some described as subspecies whose taxonomic status has been misinterpreted. Eunota togata togata applies to adults marked with broadly sinuate inner margins on shiny brown elytra common across northern coastal Gulf of Mexico. Eunota togata fascinans (Casey,1914), new synonymy, incorrectly applied to populationsin western Texas and New Mexico, United States, is considered a junior synonym of E. togata globicollis (Casey,1913), the predominant subspecies with broadly sinuate inner margins on coppery elytra found from eastern New Mexico and western Texas into the Southern Great Plains of North America. Eunota togata leucophasma, new subspecies, is comprised of adults with mostly white elytra that are isolated in Hudspeth County, Texas, and Doña Ana, Otero, and Torrance Counties, New Mexico. Intergrades between E. togata globicollis and E. togata leucophasma, new subspecies, are found sporadically in eastern New Mexico and western Texas; however, suggested intergrades between E. togata globicollis and E. togata togata in western Texas are reinterpreted as more typical of intergrades farther north in New Mexico. Adults marked with acutely sinuate inner margins on darker elytra found only in northcentral Kansas to southeast Nebraska should be referred to as E. togata latilabris (Willis,1967), new status. All subspecies are collectively known as the white-cloaked tiger beetle. Geological conditions influencing development of saline habitats and subsequent evolution of divergent white E. togata subspecies in Texas and New Mexico, and darker E. togata subspecies in Kansas and Nebraska, are discussed and compared to more uniformly marked E. togata subspecies found elsewhere in North America.
Es gibt zahlreiche Publikationen, die dokumentieren, dass Wirbeltiere in das Beutespektrum von Spinnen gehören können, wobei offensichtlich insbesondere Amphibien und Reptilien erbeutet werden (z.B. De Armas 2001, Menin et al. 2005, Toledo 2005, Maffei et al. 2010). Solche Berichte stützen sich fast immer auf Beobachtungen aus den Tropen.
The tortoise beetle, Cassida sphaerula Boheman, 1854 (Coleoptera: Chrysomelidae: Cassidinae: Cassidini) is endemic to South Africa. Its endemic host, Arctotheca prostrata (Salisb.) Britten (Asteraceae) has been introduced in other countries where it is becoming invasive. Cassida sphaerula could provide a potential biocontrol of Arctotheca weeds as it spends the entire life cycle on this host. An intensive field study, with rearing, photography, and short films of C. sphaerula was conducted in its native habitat to document the life cycle. A checklist of Cassidinae genera in South Africa, along with 19 new host records for Cassidini species in South Africa are presented. Oothecae are simple, with few laminate membranes enclosing fewer than five eggs. There are five larval instars. Larvae and adults feed by making a series of cuts in the ventral cuticle, forming an arc, and they consume the mesophyll as the cuticle is rolled to one side. This creates many ventral craters, thickened on one margin with the rolled cuticle; these ventral craters correspond to ‘windows’ in the dorsal leaf surface where the dorsal cuticle is left intact. This unusual feeding pattern is known in three Cassida species, all in South Africa. Like many tortoise beetles, instar I initiates a feces-only shield on its paired caudal processes (= urogomophi); this construction is retained, along with exuviae, by subsequent instars. The shield construction was studied by film and dissections. This revealed that the columnar or pyramidal shield in this species has an exterior of dry or moist feces that obscures the central nested stack of exuviae, each exuviae compressed onto the caudal processes. Pupae may retain the entire larval shield of exuviae and feces or only the 5th instar exuviae; this behavioral flexibility in pupal shield retention is novel for tortoise beetles. Behaviors of C. sphaerula are discussed in the context of phylogenetic characters that can give evolutionary insights into the genus, tribe, and subfamily.

We describe a new species of Dravidogecko from the poorly-inventoried Periyar Plateau of Southern Western Ghats, Peninsular India. The new species Dravidogecko beddomei sp. nov. is characterized by: precloacal-femoral pores 46‒52; scales across belly 31‒33; supralabials 9–11; infralabials 8–9; lamellae on digit IV of pes 10–11. Additionally, the new species is divergent (>13%) from its related congeners. Like its congeners, the new species is currently known only from its type locality and its vicinity – the Devar Malai, Kakki Reservoir – and Sivagiri Hills in the Periyar Plateau of Southern Western Ghats. This discovery further increases the list of new reptiles described from this under-studied massif in the Southern Western Ghats.
A new species of echinoderid kinorhynchs, Echinoderes xiphophorus sp. nov. collected from oxidized brown silt at the deepest depression in the Sea of Japan, North-West Pacific, is described and illustrated using light and electron microscopy. This new representative of the most speciose kinorhynch genus is characterized by the unique set of spines and tubes and can easily be distinguished from most of its congeners. The second trunk segment bears three pairs of tubes in subdorsal, midlateral and ventrolateral position in both sexes; one pair of tubes on trunk segment 5 in lateroventral position and on trunk segment 8 in sublateral position; aciculate lateroventral spines on trunk segments 6–9; aciculate middorsal spines on trunk segments 4, 6, 8. This species is well recognized by very long tergal extensions of the posteriormost segment, some of the longest within the family Echinoderidae. Males of Echinoderes xiphophorus sp. nov. are well distinguished from all the congeners by extremely long sword-like appendages dorsally to three pairs of penile spines. The species constitutes the first deep-sea representative of the Echinoderidae in the Sea of Japan and the deepest representative of the Kinorhyncha in this sea.
We report here the results from two field trips to collect Odonata in the Crocker Range National Park in western Sabah, Borneo, Malaysia. Thirtysix species were collected. Telosticta fugispinosa had not been described at the time of collection, nor had the two Devadatta species. There was no published record of Protosticta species cf kinabaluensis before the 2012 expedition, nor of Drepanosticta species cf crenitis.
During a survey of the fishes in the region of the Wonga-Wongué Presidential Reserve, 14 new populations of the subgenus Chromaphyosemion Myers, 1924 were found. These observations extend the previously known distribution range of the subgenus 120 kilometres southward. None of these populations could be related to any described species. Based on the colouration of the males and females, together with a genetic marker (mitochondrial DNA cytochrome b sequences), the populations studied are grouped into six new species which are described in this article, all close to Aphyosemion alpha Huber, 1998 with which they share the presence of a black alpha-shaped mark on the pre- and post-opercular region. The group composed of A. alpha and the six new species is referred to here as the A. alpha species group. All the new species, A. aurantiacum Chirio, Legros & Agnèse sp. nov., A. barakoniense Chirio, Legros & Agnèse sp. nov., A. flammulatum Chirio, Legros & Agnèse sp. nov., A. flavocyaneum Chirio, Legros & Agnèse sp. nov., A. pusillum Chirio, Legros & Agnèse sp. nov. and A. rubrogaster Chirio, Legros & Agnèse sp. nov., are further unambiguously diagnosed by unique combinations of colour patterns, making it possible to generate an identification key for the A. alpha species group. It is likely that the coastal dunes of Wonga-Wongué that form a sandy relief, could have led to the fragmentation and then isolation of the hydrographical networks that flow into the Atlantic Ocean, making possible a significant number of allopatric speciations.
The hoverfly genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) comprises 250+ described species, of which 36 are reported from the Iberian Peninsula. The high species diversity linked to the low degree of morphological differentiation between some species, which is even lower in females, leads to a high taxonomic complexity in this genus. The aim of this work is to confirm the morphological and molecular validity of an undescribed species of Eumerus, which is widespread in the Iberian Peninsula. The new species is described and compared with similar species. The genitalia of the new species are similar to those of Eumerus clavatus Becker, 1923 and Eumerus uncipes Rondani, 1850, but also share some features with Eumerus nudus Loew, 1848. The COI-5’ barcode is provided for the new taxon and analysed together with those of other named Eumerus sequences/species publicly available online. In the light of the morphology and barcoding data, the systematic position of the new species is discussed.
Elusive flaws are identified in techniques widely adopted to organize the Material Examined sections in taxonomic publications, mostly regarding the usage of the term ibidem and the nesting of information such as country and states. Logical errors are identified that prevent objective retrieval of the original information and can hinder or block its interpretation, even in case-by-case analyses. It is demonstrated that the free usage of ibidem in the sense of “same as previous except as follows” compromises the interpretation of data, characterizing bad practice. Solutions are proposed for the precise usage of both the term ibidem and the nesting technique. A new technique for organizing, compressing, and presenting information, called grid-setting, is described and evaluated. Its most notable practical effect is that the Material Examined section becomes literally a coded data sheet, which can be accurately converted back to spreadsheet format. In addition, the grid-setting technique was able to generate texts up to 30% shorter than those edited with the best-known traditional techniques. The new ideas and fixes are incorporated into a new software, flexible enough to process varied and unlimited data into largely user-defined texts, which remain nevertheless universal in their format and logical interpretation.
