Clavaptera ornata n.gen. et sp., a new genus and species of Carventinae (Hemiptera: Heteroptera: Aradidae) from Northland,New Zealand

Abstract

Clavaptera ornata gen. et sp. n. from leaf-litter from North Cape, Northland, New Zealand, is described and figured. This new genus falls within Group 1 of the Carventinae as proposed by Usinger & Matsuda (1959), and shares some characteristics of Carventaptera and Neocarventus, but it is readily distinguished from these genera by the medial fusion of the mesothorax and metathorax and the presence of a large hexagonal median prominence in the region of fusion. The holotype male was collected in leaf-litter near Serpentine access road, 4 miles from Spirits Bay road and the allotype from the Tapotupotu Stream area, at the base of Cape Reinga.     

New Aradidae from Ecuador (Hemiptera,Heteroptera, Aradidae)

As an addition to the presently poorly known aradid fauna of Ecuador, 3 new genera and 4 new species are described: Osellaptera setifera gen. n., sp. n.; Kormilevia ecuadoriana sp. n. both belonging to Mezirinae; and Carventinae Cotopaxicoris cruciatus gen. n., sp. n. and Onorecoris piceus gen. n., sp. n. An updated key is provided for all species of the Neotropical genus Kormilevia Usinger & Matsuda, 1959.     

Distribution of domestic triatominae and stratification of Chagas Disease transmission in Oaxaca, Mexico

Mexico has 18 species of Triatomine bugs (Hemiptera: Reduviidae) reported to be vectors of Trypanosoma cruzi. Chagas Disease is widespread in Mexico, with up to 3.5% seropositivity of human transfusion blood. The State of Oaxaca has the longest history of endemic Chagas Disease, based on acute and chronic case reports, and of entomological surveys in the country. However, the State health care services need more information on current risks of vector transmission. In order to identify and characterize areas of transmission in Oaxaca and to stratify the vector potential, the distribution of domestic Triatominae was surveyed during 1996-98 in collaboration with the primary health care services and local communities. Villages were studied in 11% of 570 municipalities in Oaxaca. Eight triatomine species were found in domestic and peri-domestic habitats: Triatoma barberi Usinger, T. bolivari Carcavallo et al., T. dimidiata (Latreille), T. mazzottii Usinger, T. nitida Usinger, T. pallidipennis (Stal), T. phyllosoma (Burmeister) and Rhodnius prolixus Stal. For each triatomine species in Oaxaca, the range of distribution and habitat characteristics are described. Habitat partitioning, principally based on altitude and mean annual precipitation, limited the overlap of distribution between species. Relatively consistent altitude of human settlements facilitates the dispersion of individual species within microregions. Entomological indices of house infestation were used to estimate that approximately 50% of the human population (1,874,320 inhabitants) would be at risk of vector transmission, with a minimum of 134,320 infected people and 40,280 chronic cases of Chagas Disease currently in Oaxaca.     

Preliminary results of random amplification of polymorphic DNA among Triatominae of the phyllosoma complex (Hemiptera, Reduviidae)

In Mexico, Triatoma longipennis (Usinger), Triatoma picturata (Usinger), and Triatoma pallidipennis (Stal), primary Chagas disease vector species of the phyllosoma complex, were analyzed by randomly amplified polymorphic DNA (RAPD). Sixteen decametric primers resolved individual profiles not identical, but partially discriminative between species. Analysis based on pairwise presence/absence comparisons between the three species was performed using three primers and two outgroup species Triatoma infestans (Klug) and Triatoma barberi (Usinger). Fifty-three bands in total were scored, although only two bands were constant among the three phyllosoma complex species. Two other bands were constant only for T. longipennis and T. picturata together, and not present in T. pallidipennis. Neighbor Joining tree and the multiple correspondence analysis discriminated T. pallidipennis clearly from the other two species, although there was overlap between T. longipennis and T. picturata. The results indicate a close relationship between the studied species and support the hypothesis of their recent evolution. The suitability of RAPD to discern populations within the species is discussed.
