Heteropeza
Heteropeza is a genus of gall midges and wood midges (family Cecidomyiidae) comprising approximately six described species. The genus is notable for its unusual paedogenetic life cycle, in which immature larvae reproduce parthenogenetically without metamorphosis to the adult stage. Heteropeza pygmaea, the best-studied species, has been observed in association with shiitake mushrooms (Lentinula edodes) and exhibits unique chromosomal biology including chromosome elimination during early embryonic development.
Tegenaria pagana
Rural Funnel-web Spider, House Funnel-web Spider
Tegenaria pagana is a small funnel-web spider in the family Agelenidae, first described from Greece in 1840. It is a synanthropic species strongly associated with human habitations, earning it the common name 'house funnel-web spider.' The species is native to the Palearctic region from Europe through North Africa to Central Asia, but has been introduced globally and is now established on multiple continents. A 2013 taxonomic revision substantially reduced its synonymy, consolidating several previously recognized species. It has been studied as a comparative model for eye development and troglomorphic evolution in cave-dwelling spiders.
