a recently described species of dysdercus, named dysdercus stehliki schaefer, 2013 (hemiptera: heteroptera: pyrrhocoridae), found in viçosa, minas gerais state, brazil, feeds upon the seeds of fallen fruits of sterculia chicha a. st. hil. (malvales: sterculiaceae). the biology and immature stages’ descriptions of d. stehliki were assessed in two environments: laboratory and field. individuals o...

We describe 27 new species of parasitoid wasps of the genus Orthocentrus (Ichneumonidae: Orthocentrinae) from the Neotropical region, where previously only one species of the genus (O. insularis Ashmead) was known, and provide a key to all described Orthocentrus species of the region. Based on previous studies and additional material that we have seen from the region, describing these species i...

The genus Macrostemum Kolenati contains 105. described species, with 15 valid species in the Neotropical region. The Adults are recognized principally by wing membranes strongly marked with dark and light colors. The Neotropical species Of Macrostemum were described based on the wing colors patterns and body morphology. In this paper we present a taxonomic study of the Neotropical species, desc...

Biodiversity in the neotropical region is of enormous importance, specially related to the future exploitation of this natural resource for food production, medical applications and restoration ecology and technology. Knowledge of this biodiversity and its conservation represents an important step from the scientific and applied point of view. Neotropical biodiversity is endangered by human int...

Rhynostelis Moure & Urban is a monotypic cleptoparasitic neotropical anthidiine genus currently known from two females. Herein, we describe and illustrate for the first time the male and its genitalia and it is confirmed that Rhynostelis parasitizes nests of Eufriesea. An identification key to the genera of cleptoparasitic anthidiine from the Neotropical region is also presented.

The bombyliid genus Lepidophora has a distribution restricted to the New World. The genus is composed by eight species, which are revised and redescribed herein: five restricted to the Neotropical region (L. acroleuca Painter, 1930, L. culiciformis Walker, 1850, L. cuneata Painter, 1939, L. secutor Walker, 1857 and L. trypoxylona Hall, 1981), two restricted to the Nearctic region (L. lepidocera...

Aim Although vascular epiphytes are important components of species richness and complexity of Neotropical forests, vascular epiphytes are under-represented in large scale biogeographical analyses. We studied the diversity, biogeography and floristic relationships of the epiphytic flora of the Yasunı́ region (Western Amazonia) in a Neotropical context, with special emphasis on the influence of t...

The Aleiodes melanopterus (Erichson, 1848) species-group includes 21 species, of which seven are known from the Neotropical region: Aleiodes flavistigma Shaw, 1993, Aleiodes lucidus (Szépligeti, 1906), Aleiodes melanopterus, Aleiodes mexicanus Cresson, 1869, Aleiodes politiceps (Gahan, 1917), and the new species Aleiodes shaworumsp. n. and Aleiodes vassunungasp. n. Distribution ranges of Aleiod...
