Type species.

Ortheziola vejdovskyi   Šulc, 1895, 1.

Diagnosis of genus.

Adult female in life with a series of marginal, mediolateral and medial waxy protrusions, corresponding to wax plates on slide-mounted specimens. The distribution of these protrusions and wax plates (Fig. 1) differs between species in the genus ( Kozár 2004).

Slide-mounted adult female with three-segmented antennae; third antennal segment with a slender apical seta, flagellate sensory seta and small subapical seta; second segment with one sensory pore. Eye stalk protruding, thumb-like, fused with sclerotized area at base of each antenna (sometimes called the pseudobasal antennal segment). Legs well developed; leg setae robust, spine-like; trochanter and femur fused, tibia and tarsus fused; tibia with one sensory pore and at least one fleshy sensory seta; tarsus without digitules; claw digitules hair-like, claw without a denticle. Labium one-segmented, with many setae; labium with three long setae near apex, very close together, all situated in a single setal socket . Anal ring situated in a dermal fold on dorsal surface, ring bearing six setae. Sclerotized plate present on dorsum anterior to anal ring, wider than long. Modified pores, each with two, three or four loculi, scattered over surface, appearing like microtubular ducts. Thumb-like pores forming a cluster on each side of anal ring. Abdominal spiracles ventral on anterior segments, with at least one present on each side of segments I, II or III; when present, posterior abdominal spiracles located on dorsum near anal ring, surrounded by a cluster of multilocular pores ( Kozár 2004).


The 13 species of Ortheziola   are found in the Palaearctic and north-eastern part of the Oriental Regions. For detailed distribution data of the twelve previously known species, see ScaleNet ( García et al. 2015). New locality records for several Ortheziola   species were discovered during the study of the HNHM collection, which is listed below. The distribution patterns of the species may imply the existence of several other species in these regions, which would be worth further study.


The genus Ortheziola   resembles the genera Ortheziolacoccus   and Ortheziolamameti   in having three-segmented antennae, with the basal part of the antenna fused to the eye. However, Ortheziola   differs from Ortheziolacoccus   and Ortheziolamameti   in having only a single spine band inside the ovisac band, and these genera have different geographic distribution: Ortheziola   species are distributed in the Palaearctic and north east part of Oriental Regions, Ortheziolacoccus   species occur only in Ethiopian Region, while Ortheziolamameti   species in the Oriental and Ethiopian Regions.
