Stenochrus portoricensis
short-tailed whipscorpion, microwhipscorpion
Stenochrus portoricensis is a widely distributed short-tailed whipscorpion (Schizomida: Hubbardiidae) native to the Neotropics and Nearctic regions. The species exhibits exceptional dispersal capability facilitated by parthenogenetic reproduction, enabling establishment in diverse habitats across multiple continents. Molecular studies indicate the species is paraphyletic, with a Mesoamerican origin and multiple independent introductions to Europe and the Caribbean from the Yucatán Peninsula. Sexual populations persist in natural habitats across Cuba, Dominican Republic, Guatemala, Mexico, Nicaragua, and Puerto Rico, while parthenogenetic lineages dominate introduced ranges.
Sympiesis dolichogaster
Sympiesis dolichogaster is a species of parasitic wasp in the family Eulophidae, first described by William H. Ashmead in 1888. The species epithet 'dolichogaster' refers to its elongated abdomen. Like other members of its genus, it is presumed to be a parasitoid of lepidopteran larvae, though specific host records for this species are limited. The species has been documented across a broad geographic range spanning Asia, Australia, and the Caucasus region.
Teminius insularis
Teminius insularis is a spider species in the family Miturgidae, first described by Lucas in 1857. It is widely distributed across the Americas, ranging from the southern United States through the Greater Antilles to Argentina, with records from multiple Brazilian states and French Guiana. The species has accumulated over 1,100 observations on iNaturalist, indicating it is moderately well-documented. As a member of Miturgidae, it belongs to a family of wandering spiders that do not build permanent webs for prey capture.
Thaneroclerus buquet
Thaneroclerus buquet is a species of checkered beetle in the family Thanerocleridae. The species has a notably broad geographic distribution spanning multiple continents including Europe, Northern Asia, North America, Oceania, and Southern Asia. It was originally described as Clerus buquet by Lefebvre in 1835 before being transferred to the genus Thaneroclerus.
Thoracophorus brevicristatus
Thoracophorus brevicristatus is an unmargined rove beetle described by Horn in 1871. The species exhibits a notably broad geographic distribution spanning multiple continents, including North America, Central America, the Caribbean, Africa, and Southern Asia. This wide range suggests either strong dispersal capabilities or cryptic species boundaries requiring further study.
Tramea abdominalis
Vermilion Saddlebags, vermilion saddlebag
Tramea abdominalis, commonly known as the vermilion saddlebags, is a species of skimmer dragonfly in the family Libellulidae. It is widely distributed across the Caribbean, Central America, North America, Oceania, and South America. The species has been assessed as Least Concern by the IUCN with a stable population and no immediate threats to its survival.
Trechus quadristriatus
Four-lined ground beetle
Trechus quadristriatus is a small ground beetle in the family Carabidae, distributed across North America, Europe, temperate Asia, and Africa. It has been studied primarily in agricultural landscapes, where its ecology has been examined alongside similar carabid species. The species is one of many in the large genus Trechus, which comprises numerous small, often difficult-to-distinguish ground beetles.
Trichadenotecnum majus
common barklouse
Trichadenotecnum majus is a species of common barklouse in the family Psocidae. It has been recorded across Europe, Northern Asia (excluding China), and North America. As a member of the barklice, it inhabits environments where it feeds on organic debris such as lichens, algae, and dead plant material on tree bark and rocks.
Xyonysius basalis
Xyonysius basalis is a seed bug species in the family Lygaeidae, first described by Dallas in 1852. The species has a broad distribution across the Americas, ranging from the Caribbean through Central America to North and South America. It belongs to the subfamily Orsillinae and tribe Metrargini. Available information on its biology and ecology remains limited.
Zelotes puritanus
Zelotes puritanus is a species of ground spider in the family Gnaphosidae. It has a broad geographic distribution spanning North America, Europe, Turkey, and a continuous range from Russia to Kazakhstan. As a member of the genus Zelotes, it belongs to a diverse group of active hunting spiders commonly known as ground spiders.
