Camptotarsopoda annulitarsis Stein: redescription, description of terminalia and new record to South Africa (Diptera: Muscidae).
Camptotarsopoda Strand (Diptera, Muscidae) comprises five species restricted to the Afrotropical region. The genus belongs to the subfamily Coenosiinae and tribe Limnophorini. The type-species, C. annulitarsis (Stein), is redescribed and the male and female terminalia are described and illustrated for the first time. The species is newly recorded from South Africa. The systematic placement of t...
متن کاملNew species and redescriptions of the New Zealand genus Exsul Hutton (Diptera: Muscidae: Coenosiinae).
Exsul Hutton (Diptera, Muscidae) is revised and the genus diagnosis is enlarged. The female of Exsul singularis Hutton is described for the first time. The male and female terminalia of all species are described and illustrated. Exsul alfredoi sp. n. is described and illustrated and compared with the other known species. A key to separate the species is given.
متن کاملStein E
We present a certain geometrical interpretation of the natural numbers, where these numbers appear as joint products of 5and 3-multiples located at specified positions in a revolving chamber. Numbers without factors 2, 3 or 5 appear at eight such positions, and any prime number larger than 7 manifests at one of these eight positions after a specified amount of rotations of the chamber. Our appr...
متن کاملStein Points
An important task in computational statistics and machine learning is to approximate a posterior distribution p(x) with an empirical measure supported on a set of representative points {xi}i=1. This paper focuses on methods where the selection of points is essentially deterministic, with an emphasis on achieving accurate approximation when n is small. To this end, we present Stein Points. The i...
متن کاملHolomorphic fiber bundle with Stein base and Stein fibers
A surjective holomorphic map Π : X → Y between complex spaces is said to be a Stein morphism, if for every point y ∈ Y , there exists an open neighborhood U of y such that Π(U) is Stein. In 1977, Skoda [12] showed that a locally trivial analytic fiber bundle Π : X → Ω with Stein base and Stein fibers is not necessarily a Stein manifold. Thus giving a negative answer to a conjecture proposed in ...
