Exodrymadusa inornata ( Uvarov, 1936)

( Figs. 1–10 )

Holotype: female in NHM.

Drymadusa inornata: Uvarov 1936: 510 ; Ramme 1939: 57; Uvarov 1949: 2; Georghiou 1977: 225. Exodrymadusa inornata: Karabağ 1961: 13 ; Tumbrinck 2006: 131. Exodrymadusa inorata: Harz 1969: 400 .

Description of male: Fastigium of vertex ( Figs. 1 , 8 ) almost as wide as antennal scape, its surface smooth, with an indistinct dorsal fossa; separated from fastigium of frons with an indistinct sulcus. Pronotum ( Figs. 1, 2 , 7 ) almost 1.3 times longer than wide, 1.8 times longer than its height and 1.2 times shorter than tegmina; almost straight in lateral view, metazona slightly raised; with smooth surface, anterior sulcus distinct, typical sulcus less distinct; median carina more distinct in metazona, indistinct on anterior margin; anterior margin of pronotum slightly concave, posterior margin strongly convex, narrowed to apex; metazona strongly elongated; hind margin of paranota almost straight, shoulder incision indistinct. Tegmina ( Figs. 2 , 7 ) brachypterous, reaching to end of 5th abdominal tergite, its apex narrow. Prosternum with 2 wide, U-shaped spines. Mesosternal lobes narrow triangular, its apex pointed; metasternal lobes wide triangular; inner margin of fore femur and outer margin of middle femur with 3 short spines ventrally; inner and outer margins of hind femur with 4–7 small spines ventrally. Fore tibia with 3 dorsal spines. Hind tibia with 2 dorsal, 4 ventral apical spurs. Distal narrowed part of hind femur longer than proximal broad part. Genicular lobes of hind femur without spines and tooth, of fore and middle femora without or with 1–2 small spines. Thoracic auditory spiracle large, almost twice as long as its width, partly concealed under lateral lobe of pronotum. Last abdominal tergite ( Fig. 3 ) longer than wide, with very long 2 spiniform appendages. Cercus ( Fig. 4 ) long, distinctly incurved, with a rounded projecting at outer side of apical part; strongly incurved apical arm thin; strongly pointed with a large upcurved apical tooth; its basal articulation large, downcurved, strongly widened apical part upcurved forming a hook. Subgenital plate ( Fig. 5 ) longer than wide, posterior margin with a shallow rounded incision, styli distinctly longer than depth of posterior incision. Titillators ( Fig. 6 ) with long and straight apical arms, their inner margins serrated, basal arm broader and strongly upcurved distally.

Color of male: Body pale brown with some indistinct black patterns. Face light brown, with a distinct black band between eyes; clypeus with irregular several black spots. Lateral lobe of pronotum with an irregular-shaped black spot. Fore and middle femora with several irregular dark brown stripes. Costal margin of tegmina blackened at base. Abdomen darkened because of decay.

Female: Fastigium of vertex narrower than the first antennal joint (but in fact its is almost as long as antennal scape), with a fine median sulcus. Pronotum ( Fig. 9 ) relatively long, distinctly convex in profile; anterior margin broadly rounded, posterior portion elongated, with the apex parabolic; median carina slightly perceptible even in the prozona, while in the metazona it is quite distinct; first transverse sulcus distict, typical sulcus roundly curved behind the middle of pronotum; lateral lobes oblique, convex, much longer than deep, hind margin long, distinctly sinuate. Prosternum with a pair of long, slender, straight spines. Mesosternal lobes triangular as long as their base, with attenuate apices. Metasternal lobes shorter than their base, with the apices also attenuate. Tegmina ( Fig. 9 ) reaching slightly beyond the third tergite, with parabolic apices. Appendages of last tergite long and acute. Subgenital plate ( Fig. 10 ) broadly oval, narrowed behind, strongly convex, with a double median sulcus on each side, is formed; posterior margin with a deep acute angular incision; bi-concave ventral plate (basal sclerite of subgenital plate) very large. Ovipositor ( Fig. 9 ) nearly as long as the hind femur, slightly decurved. Coloration uniformly dull brown. Face yellowish, with a narrow black antennal fascia. Pronotum without any pattern. Tegmina uniformly dark brown. Legs greyish brown ( Uvarov 1936; Karabağ 1961).

Measurements (mm): Length of body: male 42, female 33–41.3; pronotum: male 13.1, female 13.1–15; tegmina: male 16.1, female 9.5–14.3; hind femur: male 29.2, female 31.5–34.5; ovipositor 29–32.5:

Material examined: Cyprus: Xyliatos, 500 m, 25.8.1997, 1 male (leg. C. Makris) (AIBUEM); Limassol, June 1919, 1 female (Holotype); Staurovouni Mt., 2400 ft, 25.5.1937, 1 female, 24.5.1937, 1 female nymph; Pera Pedi, 2500 ft, 23.7.1937, 1 female; Mesopotamos, Mt. Troodos, 3000 ft, July 1949, 1 female nymph (leg. G.A. Mavromoustakis) (NHM).

Additional material preserved in the collection of the Agricultural Department at Nicosia: Troodos Mountains, forested area, 700–1500 m, in July–August, 4 males, 1 female. One female was collected and taken photograph at Platania in the Troodos Mts. in October.

The following published specimens were not seen: Stavrovouni, 30.6.1939, 2 specimens (leg. H. Lindberg) ( Uvarov 1949) and the specimens studied by Harz. Harz (1969) did not give the record. But, he added some new measurements and 3 original figures of female. Therefore he probably studied unknown number of females.
