Synaptolaemus latofasciatus, a new combination for Leporinus latofasciatus Steindachner, 1910 and its junior synonym Synaptolaemus cingulatus Myers and Fernandez-Yepez, 1950 (Characiformes: Anostomidae)

Leporinus latofasciatus was described by Steindachner (1910) on the basis of a single specimen collected in the rio Orinoco, Venezuela. Since then, no other specimen of the species was mentioned in the literature, and the species was only listed in catalogues, eventually mentioned and treated as a ""poorly known"" species, or even omitted in checklists of fishes from Venezuela. During a visit to the fish collection at the Naturhistorisches Museum at Vienna (NMW) to examine all the type specimens of Leporinus, we were able to study the holotype of Leporinus latofasciatus and recognize that the specimen corresponds to the species described by Myers and Fernandez-Yepez (in Myers, 1950) as Synaptolaemus cingulatus. Thus, the latter is a junior synonym of Leporinus latofasciatus and, based on that, Synaptolaemus latofasciatus (Steindachner, 1910) should be the name applied for this taxon, as a new combination. Herein new data on the holotype of Synaptolaemus latofasciatus are presented and compared with previously data from other authors. In addition, illustrations of live specimens are presented as well as new distribution records for the species.

Podochela meloi Sankarankutty, Ferreira & Cunha, 2001, a junior synonym of the spider crab Inachoides forceps A. Milne-Edwards, 1879 (Crustacea: Brachyura: Inachoididae)

Podochela meloi Sankarankutty, Ferreira & Cunha, 2001, originally described in the Inachidae MacLeay, 1838, was recently transferred to the Inachoididae genus Inachoides H. Milne Edwards & Lucas, 1842, based upon overall similarities. Placement of P. meloi in both Inachoididae and Inachoides is found to be supported by a number of synapomorphies as shown herein. Podochela meloi is shown to be a junior synonym of Inachoides forceps A. Milne-Edwards, 1879.

ERYTHROGRAM PROFILE DURING POSTPARTUM PERIOD IN HOLSTEIN COWS

With the intention to evaluate the erythrogram profile during postpartum period in Holstein cows, 142 blood samples were collected from cows during the first 90 days after parturition. Blood samples were collected from clinically healthy cows that were non-reactive to the antigen of bovine leukosis virus (GP 51). These animals were divided into nine experimental groups based on the time of the postpartum sample collection. The blood samples were collected with EDTA and submitted to the following tests: erythrocyte counts, packed cell volume, hemoglobin concentration and calculated blood indices (MCV, MCH, MCHC). There was influence of the postpartum period on the erythrogram. These alterations were observed during the first 24 h after parturition. The hemoconcentration observed during the parturition disappeared during the first 24h of postpartum. Variation of the values were observed: red blood, 5.08 +/- 0.60 and 6.11 +/- 0.72 cells /mu L; hemoglobin concentration, 9.85 +/- 1.6 and 11.46 +/- 1,40 g/dL; packed cell volume, 27.9 +/- 3.3 and 31.9 +/- 3.6 %; MVC, 50.10 +/- 5.90 and 55.27 +/- 6.88 fL; MHC, 18.19 +/- 1.63 and 19.50 +/- 2.76 pg; MCHC, 34.83 +/- 2.07 and 36.88 +/- 1.67 %. The values of the hematological components obtained in this study did not exceed the limits of the reference values, obtained from cows raised within the state of Sao Paulo.

Lipid and glucose profiles of dairy buffaloes during lactation and dry period

The purpose of this study was to analyze the influence of lactation and dry period in the constituents of lipid and glucose metabolism of buffaloes. One hundred forty-seven samples of serum and plasma were collected between November 2009 and July 2010, from properties raising Murrah, Mediterranean and crossbred buffaloes, located in the State of Sao Paulo, Brazil. Biochemical analysis was obtained by determining the contents of serum cholesterol, triglycerides, beta-hydroxybutyrate (β-HBO), non-esterified fatty acids (NEFA) and plasma glucose. Values for arithmetic mean and standard error mean were calculated using the SAS procedure, version 9.2. Tests for normality of residuals and homogeneity of variances were performed using the SAS Guide Data Analysis. Data were analyzed by ANOVA using the SAS procedure Glimmix. The group information (Lactation), Farm and Age were used in the statistical models. Means of groups were compared using Least Square Means (LSMeans) of SAS, where significant difference was observed at P ≤ 0.05. It was possible to conclude that buffaloes during peak lactation need to metabolize body reserves to supplement the lower amounts of bloodstream lipids, when they remain in negative energy balance. In the dry period, there were significant changes in the lipid profile, characterized by decrease of nutritional requirements, with consequent improvement in the general conditions of the animals.
