Zootaxa 5187 (1): 95-120, DOI: 10.11646/zootaxa.5187.1.8AbstractThe morphological ontogeny of Pilogalumna tenuiclava (Berlese, 1908) is redescribed and illustrated. The prodorsal setae of juveniles are of medium size or long and barbed, and bothridial seta is fusiform, with thick, barbed head. Larva has 11 pairs of gastronotal setae, including h 2, most are short and smooth, except for longer and barbed c 2, c 3, dp, h 1 and h 2. The nymphs have 15 pairs of these setae, most are short and smooth, except for longer and barbed c 3. Gastronotal shield of juveniles is poorly developed, with setae of d -, l -series, and h 1 in the larva, and d -, l -, h -series and p 1 in the nymphs, setae of c -series, p 2 and p 3 are inserted on unsclerotized integument. In all juveniles, a humeral organ is present.

title: DNA barcode shows discordant cases among morphological and molecular species identification in Isbrueckerichthys (Siluriformes: Loricariidae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Almeida, Rafael B. de, Azambuja, Matheus, Nogaroto, Viviane, Oliveira, Claudio, Roxo, Fábio F., Zawadzki, Cláudio H., Vicari, Marcelo R.

Despite the validation of the morphological species, molecular data to investigate gene flow and species delimitation have not been completed for all species. For this purpose, we compared sequences of COI region associated with barcoding molecular identification, aiming for a species delimitation analysis and generating population data of I. alipionis, I. epakmos, I. duseni, I. cf. duseni, I. saxicola, and I. calvus. The K2P genetic distance, molecular species delimitation analysis, and well-sustained branches in the phylogenetic tree validate I. alipionis, I. epakmos, and I. duseni, and suggest I. cf. duseni as a valid molecular operational taxonomic unit. However, no differences were detected between I. saxicola and I. calvus. The discordance between molecular and morphological species may be due to the recent dispersal of some Isbrueckerichthys representatives at the border between the Ribeira de Iguape and Tibagi basins. The isolation features of the mountainous region of Ribeira de Iguape basin and headwaters captures to uplands are presented to explain the dispersion and the cases of incipient speciation in Isbrueckerichthys lineages.

Neotropical Biology and Conservation 19 (3): 347-359, DOI: 10.3897/neotropical.19.e126767AbstractThe “ Mexclapique ” Girardinichthys viviparus, is a goodeid endemic to the Valley of Mexico basin. This species is endangered following habitat alterations due to urbanization and pollution in central Mexico over the last 70 years, which has contributed to its population decline. From collections in the aquatic systems of Tlaxcala, 160 juveniles and adults of G. viviparus were captured (17.9–53.4 standard length) in six sites located in the upper basins of the Moctezuma and Atoyac rivers and extended its distribution to the east of the state of Tlaxcala in the Tecolutla River basin. Its presence in these sites may be the result of the processes of expansion, adaptation and establishment that the species has had in central Mexico, as well as the intercommunication through artificial channels in some of these lakes. These new records of G. viviparus are vital as they provide information about the prevailing populations in habitats in a region that has experimented with anthropogenic activities conjointly with the loss of aquatic systems. Besides, the lack of aquatic biodiversity preservation projects in Tlaxcala does not guarantee its long-term conservation.

Phytotaxa 333 (2): 188-198, DOI: 10.11646/phytotaxa.333.2.2, URL: http://dx.doi.org/10.11646/phytotaxa.333.2.2AbstractDuring a bioprospecting of fungi producing antimicrobial volatile organic compounds, two Verticillium -like isolates from coffee branches were obtained by a parallel growth technique using Muscodor albus CZ 620. Micro-morphological characteristics and phylogenetic analyses showed that both isolates belonged to Simplicillium and represented a new species, namely S. coffeanum. In the test for antimicrobial activity, the mixture of volatiles emitted by S. coffeanum COAD 2057 inhibited the growth of Aspergillus ochraceus, A. tubingensis, A. sydowii and A. niger on PDA. Among the compounds of volatile mixture, 1-Propanone, 1-(5-methyl-2-furanyl)-, Cyclopropane, 1-ethoxy-2, 2-dimethyl-3-(2-phenylethynyl)-, and 2-Propenoic acid, 3-(2-formyl-4-methoxyphenyl)-, ethyl ester, (E)- possessed the highest percentage of peak per area. Therefore, S. coffeanum has potentially biocontrol ability through the emission of antimicrobial volatiles.
