(nē-ot'ĕ-nē),
Prolongation of the larval state, as in the Mexican tiger salamander or axolotl, or in certain termite castes held in the larval stage as future replacements of the queen. Compare: pedogenesis.

neoteny

(nē-ŏt′n-ē)
n.
1. The retention of juvenile characteristics in the adults of a species, as among certain amphibians. Also called pedomorphism, pedomorphosis.
2. The attainment of sexual maturity and subsequent reproduction by an organism still in its larval stage. Also called pedogenesis2.

The non-functional neotenic females in incipient Coptotermes colonies may represent a vestigial trait wherein the pathway still exists but has lost its function, whereas it was conserved in termites such as Reticulitermes (Pawson & Gold 1996; Myles 1999).

Neotenic formation in field colonies of Coptotermes lacteus (Froggatt) in Australia, with comments on the roles of neotenics in the genus Coptotermes (Isoptera: Rhinotermitidae).
Glow-worm fireflies, which are characterized by flightless, neotenic females that emit continuous light to attract flying males, are unusual in North America (Lloyd 1997b; Branham & Wenzel 2003).
This is in contrast to the monogamy displayed by the flightless, neotenic females of another North American firefly, Photinus collustrans (Wing 1984, 1988).
Snyder (1920) speculated that these neotenic individuals may leave the main nesting area with a small group of workers in order to establish distinct bud nests.
In 4 "queenless" colonies, the founding queen had been replaced by at least 1 neotenic female 2-6 years prior to this experiment (Long et al.
However, locus Rf 24-2 in Colony 5, which contained 14 neotenic females, contained 3 alleles in 5 genotypic classes; 4 homozygous genotypes were scored at Rs 33.
In Colony 5, the resource in which workers harbored 2 unique alleles also contained the king, all 14 neotenic sisters, and all of colony's eggs and instars 1-3.
COLONY 1 WAS QUEENRIGHT; THE OTHERS WERE HEADED BY AT LEAST 1 NEOTENIC FEMALE.
The genotypes sampled from the fourth queenless colony, which contained 14 female neotenics, indicate that genetic differentiation had begun to develop among the resources.
This will depend on the potential of secondary reproductives or neotenics trapped in the crates.
