: Stink bugs (Hemiptera: Pentatomidae) are a group of about 5,000 species distributed worldwide, many of them phytophagous with economic implications as crop pests. Rice ( Oryza sativa L.) is one of the leading agricultural products for human consumption. In neotropical rice fields, hemipterans are the primary pests, with stink bugs being the worst affecting crop productivity, standing out the genus Tibraca Stål in terms of economic damage. In addition, rice crops may represent important feeding and mating sites for other stink bug species taxonomically related to Tibraca , which could play the role of potential pests, making it necessary to study the pentatomids associated with this crop in the Neotropics. This work aimed to report the presence of Glyphepomis adroguensis Berg, Hypatropis inermis (Stål) and Paratibraca spinosa (Campos & Grazia) associated with rice in the main rice-growing areas of Argentina. Material collected during 2017-2018 from commercial fields in north-eastern Argentina, the central rice-producing region, was identified. The rice variety on which the specimens were collected, crop status (growing season - post-harvest) and crop phenology were considered. As a result, the association of the mentioned species with rice in the provinces of Chaco and Corrientes, Argentina, is reported. Moreover, the genus Paratibraca Campos & Grazia and the species P. spinosa are reported for the first time in the country.

: Dental microwear analysis is the study of enamel marks produced by ingested elements, allowing dietary inference in fossil groups. To generate these extrapolations, it is necessary to study reference specimens from biological collections. Observations on teeth of specimens treated with hydrogen peroxide (H 2 O 2 ) and/or sodium hypoclorite (naClO), a preparation technique used in some institutions, reveal patterns on the enamel surface inconsistent with dietary scars. To understand how these chemicals could be affecting teeth enamel and microwear patterns we ran controlled experiments using a Hydrochoerus hydrochaeris tooth. Distal portion was treated with naClO 1.25% for 1 minute and then with H 2 O 2 10% from intervals of 30 to 120 minutes. mesial portion was submerged in naClO 1.25% during the same intervals. Casts were made for control and treatment stages and examined in scanning electron microscope (sem) at 400x magnification. H 2 O 2 progressively softens shallow traces and at longer exposure erodes deep scars. naClO deepens the scars, changing its shape. Both chemicals homogenize enamel surface at longer exposure. Based on these results we highly recommend avoiding these chemicals and emphasize the importance of reporting their use in vertebrate collections as the inclusion of treated teeth in microwear analysis could result in erroneous dietary inferences.

: The subgenus Crewella Cockerell of Ceratina Latreille is found only in the Neotropical region, with maximal diversity in South America. A morphological study of the species in the subgenus led to the recognition of five species groups, based on several characteristics of the head, the first metasomal tergum, and the female sixth metasomal tergum. A key to the species-groups is presented. The following new species are described: C. dalyana from Colombia, C. amazonica , C. crassipunctata , and C. foveinasis from Peru, C. duplocarinata , C. guaranitica , and C. lobata from Argentina, C. acuminata from Brazil and Paraguay, and C. carbonaria from Argentina and Brazil. Lectotypes are designated for C. brunneipes Friese, C. diligens Smith, and C. vernoniae Schrottky. The following are new synonyms: C. brunneipes Friese, 1910 of C. maculifrons Smith, 1854, and C. gossypii var. asuncionis Strand, 1910 of C. gossypii Schrottky, 1907.

: Argentinean fossil woods have been studied since the end of the XIX century and numerous publica- tions have dealt with this type of fossil. A database of 324 records including fossil woods from the Carboniferous to the Pleistocene found in Argentina (including Malvinas/Falkland Islands) was built. The publications about fossil wood records through 134 years (1884–2021) can be divided into three periods, i) publications by non-Argentine researchers (1884–1940), ii) sporadic publications by researchers from Argentina (1941–1999), and iii) frequent publications by researchers from Argentina (2000–2021).

: There is an extensive lack of information on the parasitic fauna accompanying cartilaginous fish in Peru. The objective of this work was to identify the community of parasite metazoans of the cockfish Callorhinchus callorynchus (Linnaeus, 1758) (Chimaeriformes: Callorhinchidae) from artisanal fishing in San Andrés, Pisco, Ica, Peru. Thirty-one specimens of C. callorynchus were collected between June 2018 and October 2019. Following nec-ropsy, six species of parasites were obtained: Gyrocotyle rugosa Diesing, 1850 (Cestoda), Callorhynchocotyle callo- rhynchi (Manter, 1955) (Monogenea), Callorhynchicola branchialis Brinkmann, 1952 (Monogenea), Branchellion lobata Moore, 1952 (Hirudinea), Prokroyeria meridionalis (Ramírez, 1975) (Copepoda) and an unidentified spe- cies of the Anisakidae family (Nematoda). The G. rugosa tapeworm was the most prevalent parasite (77.42%), followed by the monogenean Cle. callorhynchi (54.84%) and finally the copepod P. meridionalis (16.13%). The total body length and sex of Ca. callorynchus showed no association with respect to the parasitological indices of prevalence, intensity, and mean abundance. Cle. callorhynchi and Cla. branchialis were registered for the second time in the same host, but for the first time in the department of Ica. However, the present study constitutes the first geographic record of G. rugosa , B. lobata , and P. meridionalis , and a new host for an unidentified species of the Anisakidae family in cockfish in Peru.
