A new species of Leptoconops Skuse from Argentina, description of the male of L. casali Cavalieri & Chiossone and a key to the Neotropical species (Diptera: Ceratopogonidae)

A new species, Leptoconops (Proleptoconops) chacoensis, is described and photographed from a female collected in a forest area of the Chaco province, Argentina. This is the first record of the subgenus L. (Proleptoconops) Clastrier from the Neotropical region south of Mexico, and the new species is compared with L. (P.) werneri Wirth & Atchley from southern USA and Mexico and L. (P.) aviarum from Tajikistan. Besides, the first description of the male of L. (Leptoconops) casali Cavalieri & Chiossone is provided, from males collected associated with females in La Rioja and La Pampa provinces, Argentina, and this species is newly recorded from several areas of the country, significantly enlarging its geographical distribution. In addition, a key to Neotropical species of the genus is provided.

Macrolichens from Chaco National Park (Chaco Province, Argentina)

A study of the macrolichens diversity from Chaco National Park was conducted. Thirty-six species were identified, three of which are recorded for the first time from Argentina (Dirinaria melanocapa, Pyxine petricola var. convexula, and P. pungens). Moreover, the distribution of 27 species in the country is extended, including new records for Chaco province and, additionally, for other provinces of the region. An identification key for species is here provided and the geographic distribution of each one in Argentina was revised.

FAMILY MEDIATION IN COMPARATIVE KEY: ARGENTINA AND MEXICO

The following article, entitled: “Family Mediation in comparative key: Argentina and Mexico”, analyzed the juridical norms related to family mediation in the Chaco Province, Argentina and Nuevo Leon State, Mexico. It was used the qualitative approach, based on the study, analysis, critical view, and comparison between the legislations of both States and theoretical scientific investigations indexed in vLex, Dialnet and Scopus to ensure the accuracy of the information. It was found that the juridical design established for family mediation not only obstructs its conception as a method to access to daily justice, but also the lack of specific regulations makes difficult to work with. From the comparative study, it was concluded the necessity of introducing juridical proceedings and good practice in the familiar mediation professional activity in the Mexican juridical system, especially the conception of the mandatory prejudicial mediation in family conflicts with children involved.

Production, Development, and Environmental Policies: Paradoxical Landscapes in Colonia Aborigen Chaco (Ex-Aboriginal Reserve of Napalpí, Argentina)

This article examines the experience of an Indigenous development plan carried out between 2005 and 2010 in Colonia Aborigen Chaco, an Indigenous settlement located in Chaco province, Argentina, originally established in 1911 as the Aboriginal Reserve of Napalpí. On the reserve, inhabitants were forced to settle down as the State appropriated their traditional territories. Here, I propose a critical analysis of this experience with ethnographic description pertaining to the long historical processes that inhabitants of Colonia Aborigen endured, which systematically subjected them to alimentary, educational, productive, and religious routines aimed at transforming them culturally. I intend to demonstrate that it is necessary to review a series of assumptions, which are quite prevalent in Indigenous policies, about what an Indigenous person, an Indigenous territory, and an Indigenous development are supposed to be. I emphatically assert that it is necessary to have a critical approach towards these historical processes of constitution in order to better understand the expectations Indigenous people have about their realities and development.

First records of the minor pest termite Eucryptotermes hagenii (Müller, 1873) (Blattodea, Termitoidae, Kalotermitidae) from the Chaco Dominion in Argentina

Eucryptotermes Holmgren, 1911, comprises 2 species of Neotropical drywood termites with phragmotic head soldiers. We report the presence of Eucryptotermes hagenii (Müller, 1873) in native forests of the Chaco Dominion and Chaco Province, enlarging its distribution and recording the genus and species for the first time in Argentina. Eucryptotermes hagenii abundance was estimated as intermediate by standardized sampling. Eighteen morphometric characters were measured in soldiers and alates, and 9 of them provided new data. The colonies, located inside living trees trunks and dead wood, were composed of reproductives, soldiers, pseudergates, and immatures.

First report of Schulzia travassosi (Nematoda, Trichostrongylina, Molineoidea) for amphibians of the Chaco region in Argentina and proposal of Oswaldocruzia melanostictusi nov. comb.

This is the first record of the nematode parasite Schulzia travassosi (Trichostrongylina, Molineidae) in two Argentinean amphibians, Leptodactylus bufonius and Rhinella major, collected in two localities of the Chaco region, Las Lomitas (Formosa Province) and Taco Pozo (Chaco Province). The species was observed using light and scanning electron microscopy (SEM) and compared with previous studies of Paraguayan specimens. Regarding metric characters, the measurements found in Argentinean specimens generally did not differ from those of Paraguayan specimens; some differences were observed in the total length of males and females (some longer and some shorter than Paraguayan specimens), length of the oesophagus (in almost all specimens shorter than in Paraguayan ones) and position of the vulva (nearer to posterior end in Argentinean specimens). The branches and sphincter of ovejector are slightly longer than in Paraguayan female specimens. In males, ray 4 is almost the same length as rays 2, 3 and 5, 6. Cephalic end, cephalic vesicle, synlophe and vulvar depression were viewed under SEM. Schulzia melanostictusi Chopra, Shing and Kumar, 1986 is reassigned as Oswaldocruzia melanostictusi (Chopra, Shing and Kumar, 1986) nov. comb.
