The life cycle of water mites is complex and includes the egg, larva, protonymph
, deutonymph, tritonymph, and adult.
The deutonymph or hypopus is a developmental instar of mites, and in H propus it is one of 5 juvenile stages including the prelarva, larva, protonymph
, deutonymph, and tritonymph.
the first, second and third quiescent is between the larva and protonymph
and deutonymp, deutonymph and adult respectively.
Similar scales were reported by Judson & Hardy (2001) on a protonymph
from Tobago, and from only near the posterior margin of the carapace in C.
The newly emerged protonymph
was slightly larger in size, pale yellowish green in colour and octapod in nature.
Stages in the life cycle of Dermatophagoides include egg, larva, protonymph
, tritonymph, and adult.
Nesochernes gracilis norfolkensis Beier 1976: 2 males, 2 females, 1 tritonymph, 1 deutonymph, 1 protonymph
from Filmy Fern Walk, 29'01'S, 167[degrees]57'E, Norfolk Island National Park, Norfolk Island, Australia, 30 November 1984, litter under Araucaria heterophylla, TA.
Paratypes: 1 male (CNANT0186), 1 female (CNANT0187) deposited in CNAN, 1 female (CAAMS-PS001), 7 tritonymph, 2 deutonymph, and 1 protonymph
, with same data as holotype (CNAN).
Nymphs: Much like adults, but trichobothrial patterns as follows: tritonymph with 14 on fixed finger and 8 on movable finger; deutonymph with 9 on fixed finger and 6 on movable finger; and protonymph
with 3 on fixed finger and 1 on movable finger.
Koch 1879) included all sensory structures of the protonymph
and showed that the arrangement of sensory organs such as setae, trichobothria and slit organs was constant in all examined specimens and may have the potential to serve in the identification of spiders at the generic and species level (Rybak & Pomorski 2003).
