Reuteria serratis sp. n.

( Fig. 2 )

Type Material: HOLOTYPE: Siirt: 13. VII. 2009, 1 male, I. Özgen coll. & B. Çerçi det. ( LEMT).

Differential diagnosis: Combination of following characters differentiates this species from its congeners; background coloration green with white maculation, membranal cells white with green maculation, left paramere with a long lateral process which is straight, perpendicular to the body and bears a small dent directing downwards apically, right paramere V-shaped and bearing small denticules on both processes, vesica with two sclerotized processes as in Fig. 2 D–E.

Description of male:

Coloration: Background green, with white staining. Head pale green with four yellowish dots, antennae missing. Pronotum green, posterior lobe with three diffuse longitudinal pale stripes. Scutellum whitish with green lateral borders and green median stripe. Hemelytra green with white staining, membranal cells white with green staining. Legs missing.

Vestiture: Setae are missing due to poor condition of the specimen.

Structure: Length 3.6 mm, body oblong-ovate, 3.6 × as long as width posterior margin of pronotum. Head transverse, ocular index 1.4. Antennae missing. Pronotum transverse, posterior margin 1.7 × as wide as anterior margin, 2.3 × as wide as long. Hemelytra parallel sided. Genital opening with sclerotized spine along left margin. Left paramere Y-shaped, lateral process forming almost 90 degrees angle with body of paramere, apically provided with small dent directed downwards ( Fig. 2B ). Right paramere V-shaped, lateral process closer to base, directed obliquely and bearing several denticules, apical process straight and bearing small denticules as well ( Fig. 2C ). Vesica with two processes as in Fig. 2 D–E.

Female: Unknown.

Etymology: The new species is named after the serrated (serratus in Latin) edges of its characteristically shaped vesical processes.

Comments: The description of this new species is based on a single male specimen in bad condition (legs, antennae and most of membrane missing). Unfortunately, it was not possible to collect further specimens from the type locality. But still, the very characteristic shapes of parameres and vesical processes allow us to describe this specimen as a novel species. General coloration and structure of the species is very similar to R. riegeri torosensis ssp. n. and R. jordanica except for the dominant green coloration of dorsum which is less dominant in R. jordanica . But the V-shaped right paramere, unique left paramere and two uniquely shaped vesical processes easily distinguish this new species from both R. riegeri and R. jordanica , as well as the rest of the Reuteria species. R. jordanica , R. riegeri and R. serratis sp. n. differ from all other species of Reuteria by the more or less dominant green coloration and white maculation of dorsum, white membranal cells with green staining, immaculate antennal segments except a black dot on the ventral surface of first antennal segment (not known in R. serratis sp. n) and simpler paramere structure.
