Eleven Species

There are currently only eleven species of Quasipaa (Anura: Dicroglossidae) distributed in southern and southwestern China to central Vietnam, southeastern Thailand, and southwestern Cambodia and presumably also in Laos (Frost 2020). Eight species of Quasipaa are currently known in China: Q. boulengeri (Günther 1889), Q. courtoisi (Angel 1922), Q. exilispinosa (Liu & Hu 1975), Q. jiulongensis (Huang & Liu 1985), Q. shini (Ahl 1930), Q. spinosa (David 1875), Q. yei (Chen, Qu, and Jiang 2002), and Q. verrucospinosa (Bourret 1937). The first seven species are endemic to China (AmphibiaChina 2020). These species have similar morphological traits and are capable of introgressive hybridization between the closely related species of this genus(Zhang et al. 2018). Despite the detailed acoustic analysis that is available to identify a variety of species and is beneficial to the study of anuran taxonomy (e.g., Microhyla species; Chen et al. 2020), advertisement calls have only been reported in detail for Q. spinosa (Yu & Zheng 2009; Chen et al. 2012; Shen et al. 2015) and Q. shini (Kong et al. 2016), whereas the call for Q. exilispinosa was briefly described from observations in captivity (Voitel 2000).

Abstract The genus Galea Meyen, 1833 includes at least five species of terrestrial, diurnal and herbivorous cavies that occupy grasslands and rocky scrub areas at both high and low elevations in South America. According to the available molecular and morphological data, Galea comes Thomas, 1919 is restricted to highland areas above 2000 m in southern Bolivia and northwestern Argentina. Its distributional range as well as its morphological distinctiveness from other closely related species (Galea leucoblephara and Galea musteloides) is poorly documented. Using both qualitative and quantitative morphological traits, we provided an emended diagnosis for G. comes. In addition, we added six new locality records to its known distribution.

AbstractWe describe a new frog species of the Mantidactylus boulengeri group (Amphibia: Anura: Mantellidae) in the subgenus Gephyromantis from south-eastern Madagascar. It is morphologically similar to M. eiselti and M. thelenae but differs in its advertisement calls with a distinctly shorter note duration, and in its bilobate (not single) subgular vocal sac. Like M. eiselti and M. thelenae the new species Mantidactylus enki is predominantly diurnal and calling males do not aggregate close to water bodies, indicating direct development as it has been demonstrated previously in M. eiselti. The advertisement calls of all three species are described in detail. A comparison with a further pair of cryptic species with bilobate vs. single subgular vocal sac (Mantidactylus tschenki — M. cornutus) did not reveal any consistent pattern of call variation correlated with vocal sac structure. Therefore, sexual selection may also be considered to explain differences in the colour and external structure of vocal sacs among closely related species.

The categories of calls previously described for the closely related species Pithecopus azureus and P. hypochondrialis are reassessed. In addition, the advertisement and aggressive calls of P. azureus from Brazil-Paraguay border in southwestern state of Mato Grosso do Sul in western Brazil are redescribed. Intraspecific comparisons of call traits are made for populations of P. azureus from Argentina and Bolivia, and the vocalization of P. azureus is also compared with that of the closely related species of the P. hypochondrialis Group (subclade of lowland species). Given the similarities among the advertisement calls of P. azureus, P. hypochondrialis, and P. nordestinus, it seems that acoustic traits, at least solely, should not be employed as reliable diagnostic characters among these species

The advantage of using laboratory-reared animals in the elucidation of trematode life histories is now generally recognized (Palombi, 1938; Stunkard, 1938, etc.). Further researches seem to emphasize this point. No matter how carefully controls are examined and no matter how precise is the morphological comparison between cercaria, metacercaria and adult fluke, the fact that the intermediate and final hosts have been exposed to previous infection in the wild—particularly by closely related species of worms—immediately detracts from the value of the experiments.

The Romanian fauna comprises two species of Aquarius Schellenberg, 1800, eight species of Gerris Fabricius, 1794 and one species of Limnoporus Stål, 1868, and we hereby update the distribution and provide insights on the phenology and ecology of all eleven species in this country. We furthermore update the distribution of the two closely related species Gerris gibbifer Schummel, 1832 and G. maculatus Tamanini, 1946 in southeastern Europe. Gerris maculatus is recorded for the first time from Hungary, Montenegro and Slovenia, and the first detailed localities from Romania and Serbia are given. All bibliographic records of G. gibbifer from Romania, Macedonia and Serbia are based on misidentification and this species is thus excluded from the faunal lists of these countries. Both G. gibbifer and G. maculatus occur in Croatia, Hungary, Ukraine, and probably Slovenia.

A New Species

Herein, we describe the new agamid species Acanthosaura phongdienensis sp. nov. from central Vietnam based on morphological and genetic data. Males of the new medium-sized species have a snout-vent length of up to 77.4 mm and females up to 64.7 mm. In both genders, the tail is longer than the snout-vent length. A spine occurs on each side of the neck, the rostral scute is entire, and the nuchal and dorsal crests are continuous. A postorbital spine is about half as long as the diameter of the eye-ball, and small lateral scales intermix with large, keeled scales whose tips point backwards and upwards. The new species differs genetically from the closely related species A. brachypoda, A. coronata, and A. lepidogaster by uncorrected p-distances of 13.6%, 21.7%, and 12.8%, respectively. This is the 13th species of Acanthosaura and the eighth species in the genus from Vietnam.

Technical Description

A new ectomycorrhizal fungus from southwestern China, Craterellus atrobrunneolus, is proposed as supported by morphological and phylogenetic analyses. The basidiocarps are characterized by a dark brown to brownish gray coloration, convex to plano-convex pileus with an umbilicate but not perforate center, smooth to slightly folded gray to cretaceous hymenophore, absence of clamp connections in all tissues, narrow basidia with 2–6 sterigmata, and broadly ellipsoid to subglobose basidiospores. Maximum likelihood and Bayesian sequence analyses of the ITS + nrLSU DNA regions confirm the phylogenetic position of the new species. Illustrations accompany the technical description and comparisons of C. atrobrunneolus and closely related species.

The radula morphology and variability in four European species of the family Viviparidae viz. Viviparus viviparus (Linnaeus, 1758), V. sphaeridius (Bourguignat, 1880), V. ater (Cristofori et Jan, 1832) and Contectiana listeri (Forbes et Hanley, 1853) were examined using scanning electron microscopy (SEM). Statistical methods reveal a certain value of rachidian tooth dimensional parameters as an efficient tool for taxonomy and discrimination of closely related species of the family.

Natural hybridization between species provides an opportunity to study the mechanisms that maintain independent lineages and may help us understand the process of speciation. The New Zealand tree wētā speciesHemideinathoracicaproduces F1hybrids where it lives in sympatry with two closely related species:HemideinacrassidensandHemideinatrewicki. This study looked at the viability and fertility of F1hybrid wētā betweenH.thoracicaandH.crassidensthat were collected from the wild and kept in captivity. The hybrids appeared to have normal viability from the late juvenile stage, with all male wētā maturing at a late instar. Male F1hybrids displayed normal mating behavior and one male produced offspring in captivity. In contrast to Haldane’s rule, female F1hybrids appeared to be infertile; they refused to mate and did not produce eggs. No evidence ofWolbachiainfection was identified in any of the three North IslandHemideinaspecies.
