Rem.: For Wi & al. (2010, p.679) this species shows all typical morphological features of the conifera-subgroup (Böttger-Schnack, 1999): a dorso-posterior projection on the 2nd pedigerous somite and a conical process on the distal endopodal segment of P2 to P4. Species of the conifera-subgroup are very close in morphology, and thus might easily be misidentified. However, due to the unique character of a hirsute surface ornamentation on the female genital double-somite, T. hirsuta can easily be identified without dissection.
