Orthotylus fuscescens sensu Önder (1976: 281) View in CoL .
Diagnosis
The new species is characterized by the combination of following features: unicolorous brown with orange tinge, ocular index 2.5/2.6 (♂ / ♀), shape of parameres, and vesica with a single sclerotized process resembling a diapason.
DIfferentIal dIagnosIs
We placed the new species in the subgenus Pinocapsus of the genus Orthotylus due to the close resemblence of its parameres to those of species of this subgenus, especially O. (P.) fuscescens (Kirschbaum, 1856) and O. (P.) olympicus Matocq, Pagola-Carte & Pluot-Sigwalt, 2018 . The subgenus consists of nine species in the Palearctic region, seven of which are distributed in the western Palearctic ( Aukema 2023). Çerçi et al. (2021a) provided illustrations of male genitalia of all these species. Regarding the male genital structures, the new species is distinguished from all the west Palearctic species, except O. (P.) thaleia Linnavuori, 1999 , by the presence of only one sclerotized vesical process. The single vesical process of O. (P.) thaleia has two falcate processes coming out from a common origin and diverging distally. This differs distinctly from the sclerotized vesical process of O. (P.) girayi sp. nov., provided with two flattened processes that do not diverge but run parallel to each other. The new species can be easily distinguished from all other species of this subgenus by the unique shape of its vesical sclerotized process, the remarkably small eyes, and the large ocular index of 2.5–2.6.
Etymology
The new species is named after Hasan Giray (1926–1987), a valuable scientist, who made important contributions to Turkish entomology through his faunistic research and field works. He was also the major contributor to the Diptera collection of LEMT.
Type material
Holotype TURKEY – Isparta Province • ♂; Eğirdir ; 11 Jun. 1973; F. Önder leg.; on Pinus sp. ; LEMT.
Paratype TURKEY – Isparta Province • 1 ♀; same data as for holotype; LEMT .
Description
Male
COLORATION. Brown with orange tinge, unicolorous without any patterns in head, pronotum, scutellum hemelytra, body, and legs. Membrane dark brown.
VESTITURE. Short adpressed pale setae on antennae, pronotum, scutellum, hemelytra, and legs. Head with pale semi-erect setae, denser than on pronotum and hemelytra.
STRUCTURE. Body length 4.2 mm, elongated, 3.8× as long as width of pronotum, ocular index 2.5, head remarkably short, 0.63× as long as wide, 0.75× as high as long in lateral aspect. First antennal segment surpassing clypeus by half of its length, second antennal segment 1.5× as long as diatone, 0.9× as long as width of posterior margin of pronotum, ratios of antennal segments 5:18:?:?. Pronotum strongly trapezoid, 2.2× as long as wide, posterior margin 2.8× as wide as anterior one. Hemelytra parallel-sided, surpassing apex of abdomen.
GENITALIA. Right paramere with a basal process sharply pointed, and an apical wide and flat triangular process with one of its margins serrated along its entire length, the other margin serrated only in its distal half and a small but distinct preapical tooth ( Fig. 16A–F View Fig ). Body of left paramere subrectangular, slender, with basal process small and curved almost at right angle in the middle and apically pointed, and two apical processes, one is a long tube apically blunt, the other flat and almost rectangular but slightly bent outwards, apical edge with several minute teeth ( Fig. 16G–H View Fig ). Vesica with single sclerotized vesical process, reminding a diapasone, with two flattened, parallel processes coming out from a broad stem ( Fig. 16I–J View Fig ).
Female Similar to male but differing in the following features: head 0.5× as long as wide, ocular index 2.6, first antennal segment surpassing apex of clypeus as much as ⅔ of its length, second antennal segment 1.3× as long as diatone, ratios of antennal segments 8:26:17:8, hemelytra widest in the middle, narrowing distal.
