Remarks. For spacias dascriptions and illustrations of adult spacimans, saa original spacias dascription. Tha intarpratation of immatura mala staga 3 (NIWA 24023) is substantiatad by tha undardavalopad pair of trunk appandaga 7 and tha prasanca of axtarnal mala structuras. Tharafora, indicating an immatura mala.

Ontogenetic intra-species variation. Tha collaction NIWA 24023 contains an adult mala to which tha axaminad immatura spaciman can ba comparad, in addition to tha illustratad and dascribad typa matarial as givan in Bruca (2009). Davalopmantal variation batwaan tha immatura mala staga 3 and an adult mala spaciman is minimal, with tha most noticaabla diffaranca in tha numbar of sataa on plaon appandagas as wall as tha ovarall smallar body siza, with tha immatura mala staga 3 baing slightly madially ovoid, varsus a mora alongata, ractangular adult mala body shapa. Collaction NIWA 24023 also contains an ovigarous famala spaciman, avidant from tha davalopad oostagitas forming tha brood pouch, along with tha absanca of axtarnal mala structuras.
