Oxythyrea abigail Reiche & Saulcy, 1856

( Figs. 3 A ; 4 A, J ; 5 A, J ; 6 A, J ; 7 A, G ; 8D, J ; 10 A, J ; 11 A ; 12 A, J )

Material studied. 18 L3 reared ex adults collected at: Cyprus, Karpasia Peninsula , Rizokarpaso , Pachyammos (Golden beach), N°35.641, E°34.549, 19.iii.2016, M. Hadjiconstantis lgt.

Body length 15–21 mm. Cranium: width 2.55–2.7 mm, height 1.47–1.76 mm. Cranium light brown with faint sculpture; elongate with its dorsal margin more or less convex at its entire length (length of dorsal straight portion of cranial margin less than one third of maximum width of cranium). Chaetotaxy as in Table 1. Epipharynx: Zygum with 14–15 stout conical setae and 13–14 similarly shaped setae at its proximal base. Chaetoparia with 60–90 and 61–68 setae on right and left side respectively. Acanthoparia with 6–8 falcate setae. Stridulatory area of mandibles with 9–13 transverse ridges, ridges in the apical third about ½ of the width of proximal ridges. Apical scissorial tooth of left mandible broad. Transverse proximal row of setae and sensilla on ligula composed of 6–8 stout lanceolate setae and 0–4 campaniform sensilla. Setae of thoracic legs slender hair-like. Respiratory plate of spiracle with 11–17 holes across diameter. Raster monostichous (with numerous irregular pali scattered around) composed of two semi-arcuate rows of 25–36 pali, septula elliptic more than three times longer than wide. Tegillar setae about size of pali or twice as long, only few longer setae present. Tegilla fused and densely setose (average distance between two setae about twice length of palus), campus absent. Dorsal parts of last abdominal segment densely setose, covered with equal short setae, without ring of prominent long setae or bald circular field.
