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.

Comoro Blue-Pigeon

<em>Alectroenas sganzini</em>, the Comoro blue pigeon, is a medium-sized frugivorous pigeon in the family Columbidae, endemic to the Comoro Islands archipelago in the western Indian Ocean, with occasional records from Aldabra Atoll in the Seychelles. The species inhabits dense evergreen humid forest, forest edges, and heavily wooded areas, typically from sea level to higher elevations on the main islands. Like other members of the genus <em>Alectroenas</em>, it displays striking plumage featuring a bright blue-grey body, a bare red facial patch around the eye, and a short rounded tail. Biological traits such as precise average lifespan, body length, and weight remain poorly documented in consolidated scientific literature, though it is a medium-sized pigeon typical of its genus. The Comoro blue pigeon feeds primarily on fruits, figs, and other forest products, contributing to seed dispersal in native forests. Threats include ongoing habitat loss through forest clearance for agriculture and charcoal production, along with hunting pressure. <em>Alectroenas sganzini</em> is assessed as Near Threatened by the IUCN, reflecting population declines driven by deforestation and exploitation across its restricted island range in the Comoros.
