Tabasconura gen. nov. (Neanuridae) and type species T. tapijulapana sp. nov., are described and illustrated. The new genus possesses all characters of the tribe Sensillanurini Cassagnau, and is characterised by the presence of slightly elongated tubercles on the body and also elongation and thickening of the sensillum S2 as well as S7 on antennal segment IV. Development of S7 is a character of the tribe.
The new genus Mexicaphorura, and its type species Mexicaphorura guerrerensis
sp. n. are described from marine littoral sand. The new genus is similar to Sensilatullbergia Thibaud & Ndiaye, 2006 in having very big sensilla on sensorial organ of antennal segment III, but of different shape, the kind of postantennal organ, with simple vesicles in Mexicaphorura versus composed vesicles in Sensilatullbergia and formulae of the pseudocelli.
