| Etymology | Named after Latin semitaeniatus, a feminine adjective derived from the Latin semi (half) and taenia (ribbon, stripe), hence half-striped, referring to the majority of specimens displaying broken longitudinal paramedian lines or dots in the longitudinal paramedian series as opposed to complete longitudinal paramedian lines. |
