Rhadine specum specum (Barr, 1960)

Agonum specum Barr, 1960b: 58. Type locality: "Cave-Without-A-Name, Kendall Co[unty], Texas" (original citation). Holotype (♂) in CAS [# 8157]. Note. Barr (1960b) did not give the etymology of the specific name but it certainly derives from the Latin noun specus, - us (cave). Barr believed the word could be used as an adjective since he described later (Barr 1974b: 14) a Rhadine speca gentilis . However, the word is a noun (Theil 1883: 297) and the species should have been named Agonum specus (nominative singular and genitive singular) or Agonum specuum (genitive plural). I consider that Barr’s name is not a Latin or latinized word; as such it does not need to agree in gender with the generic name with which it is combined (ICZN 1999: Article 31.2.3). Therefore, Rhadine specum , not Rhadine speca , is the correct spelling for this name.

Distribution.

This subspecies is known from a few caves in Kendall and Comal Counties, southern Texas (Barr 1974b: 13; Reddell and Cokendolpher, 2004: 158).
