Furthermore, three species, Deuteraphorura boneti (Gisin, 1953), Deuteraphorura akelaris (Jordana &amp;amp;amp; Beruete, 1983) and Spinonychiurus vandeli (Cassagnau, 1960), are redescribed based on type and new material to furnish the description of some characters, especially concerning the chaetotaxy, not considered in the original description. Keys to the recorded species are also reported.

Anaerobiosis does not change the serosal/mucosal galactose gradients which are developed in oxygen atmosphere. Dinitrophenol (10(-4) M) greatly increased the O2 uptake by the tissue and clearly inhibits the sugar transport. At 5 times 10(-4) M concentration, DNP totally prevents the uphill transport while the O2 uptake is normal. The inhibition produced by DNP does not increase by anaerobiosis. Fluoride inhibits the galactose transport and also the O2 uptake. It is deduced that in snail intestine the energy for the active transport of galactose can be supplied by aerobic as much as by anaerobic metabolism. The inhibition by dinitrophenol seems to be independent of its uncoupling action on the oxidative phosphorylation. The inhibitory effect of NaF may be due both to glycolisis inhibition and to alteration of the digestive epithelium.

The new species is separated from the other Homidia by the presence of macrochaeta p4 on Th. III and the distribution of macrochaetae on A6–A10 areas of Abd. IV. Using the description of this new species, the generalized chaetotaxy for Homidia is described and figured, following Szeptycki (1979) and Jordana and Baquero (2005). Dorsal macrochaetotaxy of all known Homidia species from China are provided. For first time we give the chaetotaxy for H. phjongiangica Szeptycki, 1973 from types, H. sauteri (Börner, 1909) from Japanese material, H. sinensis Denis, 1929 from types, H. socia Denis, 1929 from Japanese material and H. transitoria Denis, 1929 from types. A key to the Chinese species of Homidia with known chaetotaxy are also given.
