Species diversity of freshwater shrimp in Henan Province, China, based on morphological characters and mitochondrial gene.

Freshwater shrimp are a rich species group, with a long and problematic taxonomic history attributed to their wide distribution and similar morphological characteristics. Shrimp diversity and species identification are important cornerstones for fisheries management. However, identification based on morphological characteristics is a difficult task for a nonspecialist.

Taxonomy of the Hirtodrosophila melanderi species group (Diptera: Drosophilidae), with descriptions of four new species from southwestern China.

The Hirtodrosophila melanderi species group contains nine known species recorded from either the Old or the New World. All these species were thought to be strict fungivorous drosophilids. In the present study, we give supplementary descriptions for three of these known species, all recorded from Yunnan, southwestern China, H.
