Cigarette Beetle

Habitat

Inhabits temperate broadleaf and mixed forests and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Portugal. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Chunky False Brook Salamander

The Chunky False Brook Salamander (Aquiloeurycea cephalica) is a Least Concern plethodontid salamander endemic to Mexico, found in cloud forest and humid montane habitats in the Sierra Madre Oriental and related mountain ranges. The genus Aquiloeurycea is a recently erected Mexican endemic genus segregated from the broader genus Pseudoeurycea, comprising several small, robustly built (hence 'chunky') salamanders associated with high-elevation forests. Like all plethodontids, A. cephalica is a lungless salamander that breathes entirely through its moist, vascularized skin and the lining of its mouth. It is a direct developer, skipping the aquatic larval stage entirely and laying eggs in terrestrial microhabitats such as rotting logs, leaf litter, and soil. A. cephalica inhabits cool, humid forests of pine-oak and cloud forest zones in northern Mexico, where it forages for small invertebrates in the leaf litter and soil. The IUCN assesses it as Least Concern due to its reasonably wide distribution within its montane range. Deforestation, cattle grazing, and the conversion of cloud forest to agriculture represent ongoing threats to populations throughout its range.

Cigarette Beetle

Sphaericus velhocabrali is a beetle in the family Colydiidae (or allied family), endemic to Portugal and classified as Critically Endangered by the IUCN. This species is known from extremely limited localities in the Iberian Peninsula and represents one of the most threatened coleopteran taxa in Europe. The genus Sphaericus comprises small, cylindrical bark beetles associated with decaying wood and fungal substrates in old-growth forests. Sphaericus velhocabrali likely inhabits ancient forest remnants in Portugal, where it is associated with dead and decaying timber of native hardwood trees. Its Critically Endangered status reflects an extremely small known range, very few known populations, and ongoing habitat loss from logging, land conversion, and the replacement of native forest with eucalyptus and pine plantations across much of Portugal. Veteran and ancient trees that provide suitable dead wood habitat have become rare in the intensively managed Portuguese landscape. Little is known about the detailed ecology, biology, or reproductive habits of this species, and population estimates are unavailable. Conservation action for this beetle depends on the protection of old-growth forest remnants and the promotion of veteran tree retention in Portuguese forests. Its discovery and description are relatively recent, highlighting the ongoing documentation of European invertebrate biodiversity.
