Genus Fulvius Stål

Type species: Fulvius anthocoroides Stål, 1862 . Monotypic.

Diagnosis. Body length 1.4 to 5.5 mm, dark castaneous to brown, with whitish spots in the center of clavus and the base of cuneus. Head elongate and produced beyond the bases of the antennae; eyes ventrally reaching the long gula; frons horizontal or nearly so; labium extending to the posterior coxae or beyond. Pronotum trapeziform with rounded lateral borders and a sinuate posterior margin; collar prominent; calli large and confluent, occupying twothirds of the anterior portion of pronotum. Mesoscutum mostly visible. Macropterous with subparallel hemelytra, a well-developed membrane, and two closed cells. Ostiolar peritreme opening very reduced. Legs long and slender; hind tibiae longer than pro-or mesotibiae; tarsi 2-segmented with slender claws and a subapical tooth ( Ferreira & Henry 2002).

Remarks. Fulvius is a global genus with around 80 species worldwide ( Schuh 2002 –2013). Carvalho (1956) published a key to Micronesian species; Carvalho and Gagné (1968), a key to Galapagos species; Capriles (1969), a description and key to Puerto Rican species; and Kelton (1985), a key to Canadian species and discussion. Carvalho & Costa (1994) reviewed the Fulvius species for North, Central, and South America with illustrations of habitus, male genitalia features, diagnosis, and a species key; Gorczyca (2000), gave synonymies, diagnoses, redescriptions, and key to Afrotropical species; Ferreira & Henry (2002) diagnosed the genus, gave biological notes, and a biogeographic overview; Sadowska-Woda et al. (2006) discussed the structure of female genitalia; and Yasunaga & Miyamoto (2006) diagnosed, discussed, and provided a key to Japanese species ( Schuh 2002 –2013). The first analyses of phylogenetic relationships within the genus Fulvius based on DNA sequence were published by Sadowska-Woda et al. (2008). Phylogenetic interrelationships within the genus Fulvius were investigated using partial DNA sequence data from two mitochondrial genes: the 16S ribosomal large subunit and cytochrome oxidase I (COI). Specimens are easily collected in a light trap. Characters from the male genitalia of Fulvius are essential for species identification.
