That porosity is 1. the ratio of the aggregate volume of interstices in a rock or soil to its total volume; generally stated as a percentage [10]. 2. the ratio, usually expressed as a percentage, of the total volume of voids of a given porous medium to the total volume of the porous medium [22]. 3. the volume percentage of the total bulk not occupied by solid particles [22]. see also porosity, effective; porosity, primary; porosity, secondary; porosity, tertiary.?

A redescription of Ceratophysella lucifuga (Packard) (Collembola, Hypogastruridae) from North American caves
Abstract:
The problematic species Ceratophysella lucifuga (Packard) is redescribed based on topotypes from Wyandotte Cave and specimens from two other caves of the south-central Indiana karst area. This species is characterized by lack of body pigmentation, slightly reduced ocelli, absence of an eversible sac between antennal segments IIIIV, presence of long lateral sensilla in antennal III-organ, postantennal organ with somewhat subdivided posterior lobes, well developed furca and the absence of setae a92 on abdominal tergum V. C. lucifuga is similar to other cavernicolous species of the ceratophysellan lineage grouped in genera Ceratophysella Bo rner and Typhlogastrura Bonet, especially C. proserpinae (Yosii) and C. troglodites (Yosii) from Japan, C. pecki Christiansen and Bellinger from USA and C. kapoviensis Babenko from Russia.
