An Earthworm Riddle: Systematics and Phylogeography of the Spanish Lumbricid Postandrilus
While attending a scientific meeting in 1997, Marcel B. Bouché collected earthworms in eight locations in the Island of Majorca (Baleares, western Mediterranean). The study of that material led to the discovery of five new earthworm species that were included in a new genus named Postandrilus [1]. The authors also included Postandrilus bertae, formerly Cernosvitovia bertae – an earthworm species from Galicia (NW Spain) that, hesitantly, Díaz-Cosín et al. [2] had previously assigned to the eastern European genus Cernosvitovia. According to Qiu and Bouché [1], Postandrilus (Oligochaeta, Lumbricidae) can be differentiated from other lumbricids by its male genitalia. Postandrilus has their male pores located at the beginning of the tubercula pubertatis, far from segment 15 (the common position in the family Lumbricidae), and presents a larger and narrower crop and gizzard, supposedly to facilitate sperm transfer throughout the sperm ducts. Postandrilus earthworms are of medium to large size (100–420 mm), sedentary (i.e., expected low dispersal ability) and considered endogeic because all lack pigmentation, live in galleries (sometimes deeper than 20 cm) and their casts are comprised exclusively of mineral soil (pers. obs.).
