Types of Rhyparochromidae (Hemiptera: Heteroptera: Lygaeoidea) species described by Carl Peter Thunberg, deposited in the Museum of Evolution (formerly Zoologiska Institut), Uppsala University, Uppsala, Sweden, were reexamined and the taxonomic and nomenclatural problems that existed among those species discussed and resolved as required. Lectotypes are designated for Cimex caffer Thunberg, 178...

In this paper, we present a new methodology for synonym detection based on the combination of global and local distributional similarities of pairs of words. The methodology is evaluated on the noun space of the 50 multiple-choice synonym questions taken from the ESL and reaches 91.30% accuracy using a conditional probabilistic model associated with the cosine similarity measure.

A world catalog of extant and fossil Chaoboridae provides full type information, distribution of each species, references to keys, references to latest descriptions of each species, and summaries of bionomic information.  There are 51 extant species in six genera and 41 fossil species (2 unplaced) in 19 genera, two of which are extant. Chaoborus lanei (Belkin, Heinemann & Page) is a new synonym...
