CD57878B4B02CE7EFF5572EB7ED2AE6F.taxon	diagnosis	Diagnosis. On the wing patterns, the genus Jankowskia resembles Phthonosema Warren, 1894 in the postmedial line usually protruded outwards between M 1 and M 2, protruded inwards below M 2, then paralleling to the medial line. But Jankowskia differs from Phthonosema in having a yellowish brown patch outside the postmedial line on forewing; in the male genitalia, Jankowskia has a fairly simple valva, while in Phthonosema the sacculus is separated from the valva.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

Adult are mostly active at night. Most specimens from China have been recorded from 230 m to 2400 m elevation beteween June and October. The pupa was described in Nakamura and Masanao (2004) and Sato (1984). The larva were described and illustrated in Sato (1984). Larval host plants (Sato & Nakajima, 1975; Nakajima, 1975; Sato, 1976; Sato, 1980; Sato, 1984; Scoble, 1999) have been recorded from the families Aquifoliaceae, Fagaceae, Lauraceae, Rosaceae, Salicaceae, Theaceae.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

CD57878B4B02CE7EFF5572EB7ED2AE6F.taxon	discussion	Remarks. Sato (1980) stated in his description of the genus Jankowskia that the tegumen possesses a pair of posterior processes in the male genitalia. Later, Kim et al. (2001) considered Pleogynopteryx as a generic synonym of Jankowskia although J. bituminaria lacks the tegumen posterior processes. Herein, the length of tegumen posterior processes of the four new species is varying from almost absent without long setae apically (in J. obtusangula) to short, triangular with or without a bundle of long setae apically (J. curva, J. acuta and J. improjecta). So, these new species could be a series of transitional forms between J. bituminaria and other species of Jankowskia, and support the synonymization of Pleogynopteryx to Jankowskia.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

CD57878B4B00CE7FFF5573E67868ADD6.taxon	diagnosis	Diagnosis. This species is similar to J. taiwanensis and J. fuscaria in: the forewing outer margin is straight, the postmedial line is strongly protruded outwards between M 1 and M 2; the hindwing basal area is pale greyish brown; the tegumen posterior processes of male genitalia are digitiform, each with a bundle of long setae apically; the valva is broadened terminally, bearing two cluster of long setae near center, extending dorsally and ventrally respectively. But from the wing patterns, J. athleta can be distinguished by the indistinct and narrower medial line on hindwing. In the male genitalia, the tegumen posterior processes are very long, about four-fifths length of the uncus; the gnathos median process is shorter and broader, almost flat apically, about one-half length of the basal width; the juxta is almost symmetrical, with a small slightly sclerotized central process. In the female genitalia (Sato, 1980), the ductus bursae is shorter; the signum is almost hexagon.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

CD57878B4B00CE7FFF5573E67868ADD6.taxon	discussion	Remarks. Boarmia (Jankowskia) athleta geloi was recorded in Jiangsu, Zhejiang and Hunan provinces of China, by the description of Wehrli (1941). Later, Zhu (1981) considered these three provinces as the distribution of J. athleta. However, Boarmia (Jankowskia) athleta geloi was designated as a junior synonym of J. fuscaria fuscaria by Sato (1980). Thus, J. athleta is not reported from Jiangsu, Zhejiang and Hunan provinces of China in our study.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

This species can be distinguished from J. athleta based on the following characters: larger than J. athleta (length of forewing: 25 – 27 mm in male); the forewing postmedial line is broader and is almost merging with the medial line near anal margin; the yellowish brown patch outside the postmedial line is indistinct; the hindwing medial line is distinct, very broad, more than thrice width of the postmedial line. In the male genitalia, the tegumen posterior processes are much shorter, less than half length of uncus; the gnathos median process is pointed apically, the length is about equal to the basal width; the juxta is asymmetrical, the left sclerotized process is digitiform, about one-fourth length of the juxta, the right side with a short sclerotized process. In the female genitalia (Sato, 1980), the signum is oval, with 13 – 15 long and stout spines.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

CD57878B4B06CE79FF5573067908ACFE.taxon	discussion	Remarks. The shape of the signum of the female genitalia is variable among the specimens from different localities. The signum of the specimens from Mokan-shan, Zhejiang and Huangkengdeng, Fujian are more rounded than those from Xingshan, Hubei, but otherwise similar. There may be variation of the shape of signum among J. fuscaria fuscaria in different areas of China. However the number of specimens and collecting sites are too limited to solve this problem presently.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

This new species is similar to J. acuta in the wing patterns, but can be distinguished from that species by the following differences: the forewing outer margin is protruded, but straight in J. acuta; the transverse lines are indistinct; the hindwing postmedial line is almost straight below M 3, but remarkably protruded inwards in J. acuta. In the male genitalia, the tegumen posterior processes are longer, each with a bundle of long setae apically; the ventral margin of valva is not protruded outwards at middle; the juxta is symmetrical with median dorsal process, but asymmetrical, with an apical process at the left side in J. acuta.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).

This subspecies is similar to J. improjecta in: the forewing outer margin is protruded, the yellowish brown patch outside the postmedial line is faint; the hindwing medial line is equal to the postmedial line in width. But it can be distinguished by the following differences: wing colour is paler; the transverse lines are more distinct. In the male genitalia, the tegumen posterior processes are absent; the terminal half of valva is narrower than in J. improjecta; the left sclerotized process of juxta is stick-like, but lacking in J. improjecta.	en	Jiang, Nan, Xue, Dayong, Han, Hongxiang (2010): A review of Jankowskia Oberthür, 1884, with descriptions of four new species (Lepidoptera: Geometridae, Ennominae).
