Loxa viridis

(Palisot de Beauvois, 1805)

Loxa viridis is a in the Pentatomidae, characterized by holocentric with a number of 2n = 14 (12A + XY). The species exhibits inverted for and has been studied cytogenetically from specimens collected in Brazil. Its distribution spans the Caribbean, Middle America, North America, South America, and the Galápagos Islands.

Identification

Cytogenetic identification is possible: the has 2n = 14 with holocentric structure, terminal and heterochromatic regions on , and 18S rDNA signals on one autosomal bivalent. The Y chromosome is completely heterochromatic and DAPI+ (AT-rich), while the X chromosome shows homogeneous staining.

Habitat

Has been collected in Iguaçu National Park in Foz do Iguaçu, Paraná, Brazil. Broader preferences are not documented.

Distribution

Recorded from the Galápagos Islands, Caribbean, Middle America, North America, and South America. Specific collection documented from Paraná state, Brazil.

Life Cycle

Chromosomal features include holocentric with inverted for . Sex chromosomes present as univalents in metaphase I and exhibit touch-and-go-pairing in metaphase II. Kinetic activity is localized in terminal regions during meiosis.
