New Species of (Myristicaceae) from South America.

With about 70 species , is the largest genus of Myristicaceae in the Neotropics, the genus ranked in the top ten genera of abundance across Amazonia. Ten new species are proposed in this striking genus, which are described based on morphology, and are illustrated. The new species were discovered thanks to herbarium specimens collected mainly in the 1980s and 1990s when field documentations were more active.

Cryptic diversity in Cope, 1869 and description of a new species from New Mexico (Diplopoda, Platydesmida, Andrognathidae).

is a genus of small, thin-bodied millipedes found in deciduous forests of North America. Poorly understood, these organisms inhabit decaying wood and have morphologically conserved and difficult-to-identify sexual characters that have limited study historically. Recent use of scanning electron microscopy has uncovered variation in male genitalia that was previously unknown in the genus.
