Pronotum (Figs. 301, 302) compressed laterally; lateral carinae practically absent; median carina distinct, slightly raised, strongly and widely intersected by typical transverse sulcus; prozona slightly concex in lateral view, in other male more convex; metazona very short, lower than prozona, almost straight in lateral view; anterior margin of pronotum convex, posterior margin broad and shallow triangularly incised, in the other male posterior margin concave in dorsal view; prozona 3.5 times longer than metazona. Tegmina (Fig. 301, 302) squamipterous, narrow, slightly widening backwards, rounded at apex slightly surpassing end of first tergite, 3.2 times longer than wide. Prosternum swollen, almost cubic, anterior margin carinate and straight, in the other male slightly concave, posterior corners with a distinct tubercle. Mesosternal interspace narrow and long, 1.5 times longer than wide and 1.5 times narrower than mesosternal lobes. Arolium very large and wide, longer than the claws. Hind femur (Fig. 272) very narrow and long, 4.2 times longer than its height, dorsal margin slightly convex, very indistinctly serrated, ventral margin almost straight. Hind tibia with 10 inner, 9–10 outer spines, dorsal side with long hairs. Large tympanum concealed under the apical part of tegmina. Krauss’ organ with transversal fine ridges. Abdominal tergites not raised, with a small posterior projection. Supra-anal plate divided into 2 parts by a distinct transversal suture; with a longitudinal sulcus, wide in anterior part and much narrower in posterior part; sharply pointed hind margin. Aedeagus (Figs. 36 a, d) narrow at apex slightly curved foreward, with a small and acute sharp projection posteriorly; tumida of zygoma distinct (Figs. 36 a, b); tumida of cingulum absent; apodemes very broad, wider than basal valves of penis; epiphallus long and narrow, compressed laterally, with small ancorae, pseudolophi long and narrow with many distinct spines (28–31), posterior margin broadly rounded (Fig. 36 c).
Female: Body (Fig. 303) as in male but larger. Fastigium of vertex (Fig. 304) short, horizontal and depressed. Frontal ridge with a very deep and wide frontal groove. Vertex (Fig. 304) between the eyes 1.5 times narrower than vertical diameter and 1.1 times wider than transversal diameter of eye. Eye (Fig. 305) long oval, 1.6 times longer than wide. Antenna as in male, with 14 segments. Pronotum (Figs. 304, 305) compressed laterally, roof-shaped, without lateral carinae; median carina slightly raised, convex in lateral view, strongly intersected by typical transverse sulcus; metazona very short, 3.8 times shorter than prozona. Tegmina (Fig. 304) narrow, 3.3 times longer than wide, narrowly rounded at apex, not reaching to end of first abdominal tergite, but reaching to end of tympanum. Prosternum distinctly swollen, anterior margin raised as a low collar, concave in the middle, posterior swollen part with irregular small tubercles. Mesosternal interspace narrow, 1.75 times longer than wide and slightly narrower than mesosternal lobes. Metanotum and first abdominal tergite clearly ascending in lateral view (Fig.
305); other tergites almost horizontal. Metanotum and abdominal tergites with slightly raised median carina in posterior parts with a small projection posteriorly. Krauss’ organ as in male. Hind femur 4.4 times longer than its height, dorsal margin slightly convex, ventral margin straight, finelly and bluntly serrated. Hind tibia with 10 inner, 10 outer spines, dorsal side with long hairs which sparser than male. Arolium large and wide, slightly shorter than claws. Supra-anal plate as in male. Subgenital plate slightly longer than wide, almost rectangular, posterior margin with 4 rounded lateral and 1 triangular, shorter median projection. Ovipositor with short, stout and blunt valves.
Coloration. Male: Body greyish-brown with black and creamish spots, and patterns. Gena and ventral half of clypeus creamish. Basal half of antennal segments blackish, apex creamish-brown; apical 4 segments brown. Dorsal surface of head and eyes brown. Supraocellar foveola black. Pronotum brown with short black stripes and spots; ventral part of paranota cream. Outer surface of hind femur creamish with 3 transversal greenish-grey bands, with black spots along the dorsal and ventral carinae; inner and outer sides of genicular lobes blackened. Inner surface of hind tibia pinkish-red; basal parts of inner spines purple, mid parts cream and the tips black; inner half of dorsal surface pinkish-red, outer half body color with small blue or black spots, outer spines as the inner ones but their base bluish or blackish. Inner side of first 2 segments of tarsus pinkish-red, remaining part cream with small black spots. Abdomen greyish-brown with black and cream spots. Female: Body light brown with black spots, lighter than males. The cream parts of head and abdomen as in male, but weaker. Inner surface of hind femur dark milky brown with distinct black spots along dorsal and ventral carinae; genicular lobes creamish-brown. Inner surface of hind tibia weakly pink, inner spines as in male but with blackish or bluish base, outer spines with weakly darkened basal parts. Inner side of the first segment of tarsus weakly pink, remaining part body color.
Diagnosis. This new species is most related to O. yersini (Brunner) s.l. by the external appearance and the coloration of hind lengs in the Anatolian population of O. yersini s.l., but, it is easily distinguished by the structures of phallic complex, especially the shape of aedeagus which is quite narrow and pointed at apex (very distinctly wide and truncated at apex in O. yersini), the hind leg coloration, pinkish-red tibia with darkened base of spines (tibia and spines body color in the Syrian, Lebanese, Israeli specimens, but with the same coloration in Anatolian populations), the less raised prozona of pronotum (variable but more raised prozona in O. yersini yersini including the type, but more similar prozona seen in O. yersini davisi). Actually it is not easy to distinguish and identify the species using only females and also males without the genitalia, but the male phallic complex easily distinguishes the new species.
Measurements (mm). Holotype (male): body length 37.2; pronotum length 5.8 (prozona 4.5, metazona 1.3); pronotum height 5.7; pronotum width anterior 6.1; pronotum width posterior 6.8; tegmina length 6.1; tegmina width 1.9; hind femur length 16; hind femur height 3.8. Paratypes: body length: male 34.8–37.2, female 61.3–67.9; pronotum length: male 5.8–6.2, female 10.8–11; pronotum height: male 5.7–6.2, female 10.4–11.1; pronotum width anterior: male 5.9–6.1, female 9.5–9.9; pronotum width posterior: male 6.2–6.8, female 11.3–11.6; tegmina length: male 6.1–6.4, female 8.9–9.3; tegmina width: male 1.8–1.9, female 2.7–3; hind femur length: male 14.5– 16, female 22.9–23.8; hind femur height: male 3.6–3.8, female 5.2–5.4.
Etymology. This new species is named in honor of Prof. Dr. Bruno Massa (University of Palermo) for his very important contributions to Pamphagidae as well as the genus Orchamus.
Remarks. Karabağ (1963) recorded several specimens from İçel, Gözne in Turkey. These specimens may belong to this new species rather than O. y. davisi or O. y. yersini. Two genitalia published by Massa (2009: 94, 98 Figs 28, 29, 42, 43) from Latakia (Syria) and Guzeluluk [Güzeloluk] (Turkey) belong to this new species. Possibly all specimens of O. davisi in Massa (2009: 93) belong to this new species. On the other hand Massa (2009: 94, Fig. 22) also gave genitalia of O. yersini from Latakia (Syria). It seems that both species O. yersini and O. massai sp. nov. are found in Latakia. It should be stated here that the location “Akbés” given by Massa (2009) is now in Hatay Province of Turkey.
