A new species of the genus Orthozona Hampson, 1895, O. parallelilineata sp. nov., is described from China. The new species is illustrated with images of adults and genitalia, and it is compared to similar species, O. quadrilineata and Paracolax curvilineata. A distribution map of this new species is also presented.

The genus Orthozona was erected by
Specimens were collected in Xizang Autonomous Region, China, using a 220 V/450 W mercury lamp and a DC black light. Standard methods for dissection of the genitalia and preparation of the slide mounts were used (

Orthozona Hampson, 1895, 94. Type species: Madopa quadrilineata Moore, 1882.
In morphology, both Orthozona and Paracolax Hübner, [1825] share some charactersas follows: the color of the forewings is ochre to dark ochre, the antemedial and postmedial line are distinct; the distal part of valva are tongue-like, the saccular process are developed; and the ductus bursae have a pair of sclerotized stripes. However, these genera can be distinguished by the following features: the antemedial and postmedial lines in Orthozona are inwardly oblique or slightly curved but always paralleled with each other, whereas the two lines in Paracolax are oblique or wavy and seldom parallel; the reniform spots in Orthozona are not obvious, while these spots in Paracolax are obvious; the saccular process of Orthozona is finger-shaped, slightly separated from the valva, and slightly sclerotized, whereas the saccular process in Paracolax is variously shaped, e.g. digitiform, conical, truncate, etc.; and the corpus bursae of Orthozona is sac-like, with a single signum, while the corpus bursae of Paracolax is very long, more than twice as long as the ductus bursae, and with or without signum (
The proboscis is developed; the labial palpus in males is sickle-shaped, mostly covered with scale tufts ventrally; labial palpus in females with the 2nd segments straight and the 3rd segments upturned; the antenna is filiform. Thorax: quite stout; the forewing is broad, with the outer margin broad and slightly excurved; in many species of this genus, the medial line of the hindwing is indistinct and the subterminal line is slightly arched. Abdomen: slender, slightly lighter than the thorax; the uncus is slender, with a hooked apex; the tegumen is narrow and triangular; the saccus is U-shaped; the valva is simple and weakly sclerotized, with saccular process; the vesica is covered minutely granular and bears a basal cornutus; in females, the analis papili is short, the apophyses posteriores and anteriores are moderate in length, the ductus bursae is short, the corpus bursae have more extensive microspines, and a signum is present.

The species is named for the parallel medial and subterminal lines.
Orthozona quadrilineata and Paracolax curvilineata are very similar in external appearance and genitalia in both sexes. However, they are not discussed further here due to the poor condition of their materials; the relationship between these three species deserves in-depth study when the materials become available. In this paper, one female of O. quadrilineata was collected by Dr M. Owada on 25 September 1983 in Sikkim, India (genitalia slide no. NSMT4373).
