First observations of bioluminescence in Diplocardia caroliniana and juveniles of an Amynthas sp. are compared with that description of the well-known Microscolex phosphoreus. Bioluminescence of a fourth juvenile microdrile is also described. Additionally, new range extensions are identified for the three megadriles collected from Oklahoma and Georgia, USA.

This survey of the earthworms from all 95 counties of Tennessee, USA, documents the presence of 20 species previously unreported from the state, increasing the state list to 62 species. Reported from the state for the first time are: Diplocardia alba, D. alabamana, D. eiseni, D. farmvillensis, D. gatesi, D. hulberti, D. invecta, D. longiseta, D. macdowelli, D. meansi, D. michaelseni, D. nova, D. riparia, D. rugosa, D. smithii, D. sylvicola, D. texensis, D. varivesicula, D. verrucosa and Microscolex phosphoreus. In addition, one as yet undescribed species, referenced herein as Diplocardia n.sp. TN01, was collected. [ABSTRACT FROM AUTHOR]

This second major earthworm survey of the state of Oklahoma, USA, records nine taxa for the first time from the remaining 33 counties that had not previously been surveyed. The species are Acanthodrilidae: Diplocardia glabra, D. texensis, Diplocardia n. sp. OK04, Diplocardia n. sp. OK05, Microscolex dubius, Microscolex phosphoreus; Lumbricidae: Bimastos longicinctus; Megascolecidae: Amynthas carnosus; and Ocnerodrilidae: Eukerria saltensis, the first ocnerodrilid species from the state. Errata for the previous 2010 survey correct D. hulberti to D. caroliniana and D. keyesi to D. texensis in Woodward County and D. conoyeri to D. longiseta in Choctaw and McCurtain Counties; these corrections retract D. hulberti and D. keyesi as new state records. In total, the number of earthworm species has increased from 30 to 39, with 25 being native. [ABSTRACT FROM AUTHOR]

A new species of earthworm in the genus Diplocardia is described from the Invertebrate Collections of the Canadian Museum of Nature, where nearly 50 years have elapsed since they were first collected in several counties of Tennessee, USA. Most of these Diplocardia deborahae n. sp. specimens bear a single mV female pore, a characteristic otherwise rare among the 50 described species of diplocardians; only 3 of 34 adult specimens possess a single pair of ovipores. Species most similar morphologically to Diplocardia deborahae n. sp. are D. caroliniana, D. meansi and D. ornata. The geographic range of this species is discussed. [ABSTRACT FROM AUTHOR]
