Ameroscolopa gen. nov.

Type species. Scoloposcelis flavicornis Reuter, 1871 , here designated.

Description. Male. Elongate, macropterous, glabrous. Head: short, shiny, with long setae;

rostrum nearly reaching mid coxae. Thorax: Pronotum finely rugose; lateral margins carinated; calli not elevated, rounded, shiny, finely wrinkled; pronotal collar narrow; scutellum shiny, finely sculptured. Mesosternum with longitudinal median groove; metasternum apically acute. Fore femora armed with several teeth on inner margin. Fore and hind femora enlarged. Hemelytra shiny, very finely punctured. Ostiolar peritreme apically rounded, short and gently curved forward; without apparent median sulcus. Abdomen: Sternum IV in male with pair of uradenia opening (‘orifice’ sensu CARAYON 1954), a complex reticulated blister,

indicated by clump of setae. Terminal abdominal segments with long setae. Left paramere with short bifid apex.

Female. Similar to male. Ovipositor developed.

Differential diagnosis. The New World species of Scoloposcelis Fieber, 1864 are here arran-

ged in a new genus because of the following characters:

1. Femora: Old World species of Scoloposcelis have the mid and hind femora spinose as well (except for S. koreanus Jung, Yamada & Lee 2011 – see JUNG et al. (2011)). They are smooth in the species of Ameroscolopa gen. nov.

2. Left paramere: In the Old World species, it is nearly straight and ‘weakly projected at apex’ ( YAMADA & HIROWATARI 2005). New World species have a short bifid apex.

3. Ostiolar peritreme: In the Old World species curved and apically acute with a median sulcus extending in basal 3/4 of its length. New World species have the ostiolar peritreme apically rounded and ‘short and gently curved forward’ ( KELTON 1978), and without an apparent median sulcus.

Etymology. The prefix (Amero -) refers to the continent (Americas) where the species occurs,

and the suffix (- scolopa) refers to the tribe Scolopini . The gender is feminine.
