Two new species, Castanediellabrevis and C.monoseptata, are described, illustrated and compared with other Castanediella taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Castanediellabrevis can be distinguished from other Castanediella species by the short hyaline conidiophores and fusiform ...

\u3ci\u3eMcphersonarcys\u3c/i\u3e, a New Genus for \u3ci\u3ePentatoma Aequalis\u3c/i\u3e Say (Heteroptera: Pentatomidae) [PDF]
A new monotypic genus, Mcphersonarcys is erected to hold Pentatoma aequalis Say, a species formerly placed in the genus Hymenarcys. Based on the distribution of 19 character-states Hymenarcys forms a clade with its sister genus Coenus.

The Lipman-Zariski conjecture in genus one higher [PDF]
We prove the Lipman-Zariski conjecture for complex surface singularities with $p_g - g - b \le 2$. Here $p_g$ is the geometric genus, $g$ is the sum of the genera of the exceptional curves and $b$ is the first Betti number of the dual graph.

South American Melolonthinae (Coleoptera: Scarabaeidae) classification and nomenclature: some problems and solutions [PDF]
Classificatory changes are made for some taxa of New World Melolonthinae based on the examination of specimens (including type specimens) and a reevaluation of some of the characters used to justify previous classification decisions.

Log-concavity of the genus polynomials of Ringel ladders [PDF]
A Ringel ladder can be formed by a self-bar-amalgamation operation on a symmetric ladder, that is, by joining the root vertices on its end-rungs. The present authors have previously derived criteria under which linear chains of copies of one or more ...

Why breed disease-resilient livestock, and how?
Background Fighting and controlling epidemic and endemic diseases represents a considerable cost to livestock production. Much research is dedicated to breeding disease resilient livestock, but this is not yet a common objective in practical breeding ...
