Europiellomorpha Duwal n. gen.

Type species: Europiella lividellus ( Kerzhner, 1979) .

Diagnosis. Generally distinguished by small, and oval body, entirely pale antennal segments and legs; ventrally furnished with few large distinct black spots on metafemora, arranged on anterior and posterior margin; long labium reaching apex of metacoxa.

Description. Male. Body small, oval. COLORATION ( Fig. 1 G): Generally greenish; head, pronotum, mesoscutum and scutellum green, tinged with yellow; hemelytron pale. Venter greenish. Antennae pale brown, segment I and base of segment II tinged with green. Labium pale, segment I tinged with green, and apex of segment IV brown. All legs pale; metafemora ventrally with one large dark spot on anterior margin and three large dark spots on posterior margin ( Fig. 3 F); and tarsal segment III dark. SURFACE AND VESTITURE: Dorsum furnished with appressed, flat serious setae, semierect simple dark setae and soft pale setae. STRUCTURE: Head projecting anteriorly, convex; labium reaching apex of metacoxae. GENITALIA ( Fig. 6 A–D): Endosoma: Shape S–like, partly twisted medially, unequal apical processes bind with membrane saw-like projections present at edge of one process (serrated edge) ( Fig. 6 A). Phallotheca: Simple, attenuated towards apex, with blunt end ( Fig. 6 D). Left paramere: Simple, anterior process elongated, somewhat curved, and posterior process short and thumb like ( Fig. 6 C). Right paramere: Simple, leafy with narrow apex ( Fig. 6 B).

Female. Similar in color and texture as males. Genitalia ( Fig. 6 E): Bursa copulatrix trapezoidal and centrally with semi–sclerotized plates, sclerotized rings asymmetrical, somewhat triangular and lateral margins curved.

Etymology. Named after the phyline genus Europiella Reuter , to which this new genus is superficially similar. Discussion. The tiny representative species of Europiellomorpha inhabits various species of Artemisia (Asteraceae) . The external morphology is closely related with those of Europiella ; however, the saw-like serrated edge of the endosoma is regarded as an autapomorphic character for the new genus.
