RESUMEN En el presente estudio se analizaron y compararon los caracteres morfológicos de una especie de Drosophila, capturada en el bosque nublado de Intillacta, Pichincha, Ecuador. Los análisis de los rasgos morfológicos como manchas de las alas y genitalia sugieren que se trata de una especie nueva perteneciente al grupo Drosophila morelia. Por lo tanto, Drosophila nina sp. nov., descrita en el presente estudio, es la quinta especie de este grupo. Así mismo se redescribe a Drosophila ogradi Vela & Rafael, 2004 para completar la información faltante en la descripción original.

Groll,Elisa von; Moura,Luciano de A..

ABSTRACT Caraguata Bechyné, 1954 (Galerucini, Galerucina) includes 38 species exclusively Neotropical, among them two sympatric species, C. atricornis (Clark, 1865) and C. guaporensis Bechyné, 1958. Given the lack of morphological studies in this group, we aimed to characterize the adult morphology of two species, providing descriptions, illustrations and comparisons of structures of the head, thorax, abdomen and genitalia. The external morphology includes the description of head, thorax, abdomen and its appendices; the internal morphology comprises endosternites, and male and female genitalia. Some similarities were observed, such as pubescence, mouth parts, apparent sexual dimorphism on ventrite V, spermatheca and vaginal palpi. The main differences are...

RESUMEN En el presente trabajo se describen cuatro miembros nuevos del grupoDrosophila repleta capturados en dos bosques nublados del Ecuador. Las nuevas especies fueron agrupadas dentro del subgrupo D. fasciola basados en el patrón de pigmentación del tórax y la morfología de la genitalia masculina. Drosophila inti sp. nov.,D. nigua sp. nov. y D. yambe sp. nov. fueron capturadas con trampas de banano, mientras que D. carvalhoi sp. nov. fue recolectada en inflorescencias deAnthurium sp. La pigmentación del abdomen y la forma del edeago de D. nigua sp. nov., D. yambe sp. nov. y D. carvalhoi sp. nov. indicarían que están relacionadas entre ellas, mientras que D. inti sp. nov. sería más cercana aD. linearepleta Patterson & Wheeler, 1942.

El oso melero (Tamandua tetradactyla) pertenece a la familia Myrmecophagidae del superorden Xenarthra. La fragmentación del hábitat, la caza local y el mascotismo, lo ubican en la categorización "potencialmente vulnerable" en Argentina. Para la aplicación a futuro de protocolos de biotecnología reproductiva en programas de manejo y conservación de gametos se realizaron disecciones anatómicas, estudios histológicos y de morfometría espermática (mediante microscopia óptica y electrónica) en tractos reproductores de 5 hembras y 4 machos. La diferenciación de la genitalia externa entre sexos resulta dificultosa: las hembras presentan una hendidura longitudinal y los machos presentan un orificio terminal en la punta del pene. El pene, contiguo al ano, está...

Antispila oinophylla new species (Lepidoptera, Heliozelidae), a new North American grapevine leafminer invading Italian vineyards: taxonomy, DNA barcodes and life cycle

Nieukerken, E. van; Wagner, D.; Baldessari, M.; Mazzon, L.; Angeli, G.; Girolami, V.; Duso, C.; Doorenweerd, C..

A grapevine leafminer Antispila oinophylla van Nieukerken & Wagner, sp. n., is described both from eastern North America (type locality: Georgia) and as a new important invader in North Italian vineyards (Trentino and Veneto Region) since 2006. The species is closely related to, and previously confused with A. ampelopsifoliella Chambers, 1874, a species feeding on Virginia creeper Parthenocissus quinquefolia (L.) Planchon., and both are placed in an informal A. ampelopsifoliella group. Wing pattern, genitalia, and DNA barcode data all confirm the conspecificity of native North American populations and Italian populations. COI barcodes differ by only 0–1.23%, indicating that the Italian populations are recently established from eastern North America....

A grapevine leafminer found recently in table grape orchards and vineyards in the Paarl region (Western Cape, South Africa) is described as Holocacista capensis sp. n. It has also been found on native Rhoicissus digitata and bred on that species in the laboratory. It is closely related to Holocacista salutans (Meyrick, 1921), comb. n. (from Antispila), described from Durban in KwaZulu-Natal, but widespread in southern Africa and a native leafminer of various Vitaceae: Rhoicissus tomentosa, R. digitata, R. tridentata and Cissus cornifolia. Holocacista capensis has been found on Vitis vinifera both in Gauteng and Western Cape, the earliest record being from 1950 in Pretoria. The initial host shift from native Vitaceae to Vitis must have occurred much...

The occurrence and degree of taxonomie congruence is analyzed between classifications based on the external morphology and male and female genitalia of the genus Rasahus Amyot & Serville, 1843 (Reduviidae) using multivariate analyses. The results demonstrate that a classification based on size differences, and a data set of ratios are incongruent with a classification of a set of characters of the male and the female genitalia. The last two classifications are congruent with each other at a speciesgroup level, e.g., that of the R. scutellaris and R. hamatus group. The classifications are discussed and a generalized phenetic classification is given.

The anatomy of the internal organs of the male reproductive apparatus (MRA) of adults and pupae was compared among 51 species of bees, including representatives of six families. Four different types of MRA were found. The type I is present in males of the less derived families (Colletidae, Andrenidae, and Halictidae) and is characterized by three seminiferous tubules per testis, which are almost completely enveloped by the scrotal membrane. The type II is an intermediary between types III and I and is present in Melittidae and Megachilidae, as well as in some Apidae studied, being characterized by post-vesicular deferent ducts outside the scrotal membrane and by three or four seminiferous tubules per testis, except for Apis mellifera L., which has a...
