038239583353FF814592FD416F65FB10.taxon	diagnosis	Diagnosis. Species of Ancylosis are characterized mostly by the porrect, weakly or strongly up-curved labial palpus; the narrowly elongate forewing with ground color yellow to dark yellowish-brown in general, M 2 and M 3 veins merged, stalked or separated; in the male genitalia by the sub-triangular uncus, the conical or distally hooked gnathos, the narrowly elongate valva and the slender aedeagus without cornuti; in the female genitalia by the corpus bursae, or sometimes ductus bursae full of numerous thorns with a rounded base. Detailed morphological characters were described and discussed by Roesler (1970, 1973), Sinev (1986), Leraut (2014) and Bidzilya et al. (2019).	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

038239583352FF804592FF596F9CFC8E.taxon	diagnosis	Diagnosis. Ancylosis albicosta can be distinguished by the forewing with a wide white costal band (Han et al. 2025). The male genitalia are similar to those of A. oblitella (Zeller, 1848), but can be distinguished by the narrow, lingulate gnathos, which is about 1 / 3 the length of the uncus, and the elongate slender aedeagus. The female genitalia are similar to those of A. roscidella (Eversmann, 1844), but differ in the distinctly rounded anterior portion of the corpus bursae, and the forewing pattern of A. albicosta differs from those aforementioned species.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

038239583354FF854592FA556B17FBB1.taxon	diagnosis	Diagnosis. The new species is similar to A. plumbatella (Ragonot, 1888), but differs from the latter externally by the long (3 times as long as an eye diameter) porrect, weakly up-turned labial palpus and the forewing without costal band. In A. plumbatella, the labial palpus is short (equal to an eye diameter), porrect or up-turned, and the forewing has a white costal band mixed with some brown. The male genitalia of the new species are characterized by the uncus obtusely rounded at apex, the valva narrowed at the apical 1 / 4 and the aedeagus narrowed medially. In A. plumbatella, the uncus is pointed at apex, the valva is parallel sided at apical 1 / 4 and the aedeagus is narrowed distally. The female genitalia of the new species can be recognized by the subovate corpus bursae with several cone-shaped spines gathered in the posterior portion. The female genitalia of A. plumbatella differ in the elliptical corpus bursae with cone-shaped spines gathered in the medial portion.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

038239583356FF844592FD406C95FACE.taxon	diagnosis	Diagnosis. Ancylosis gozmanyella is similar to A. morbosella Staudinger, 1879. It can be distinguished by the forewing with a white costal band, the postmedial line with an inward acute angle near the posterior margin, and the two black discocellular spots connected. In A. morbosella, the forewing lacks a costal band, the postmedial line has two inward angles, and the two black discocellular spots are separated. The male genitalia of A. gozmanyella are characterized by the uncus pointed at apex, the gnathos about 1 / 2 the length of the uncus, the triangular sacculus, and the vinculum straight on the anterior margin. Ancylosis morbosella differs in the uncus rounded at apex, the gnathos about 1 / 4 the length of the uncus, the sacculus banded, and the vinculum medially concave on the anterior margin. The female genitalia of A. gozmanyella can be recognized by the small triangular papillae anales twice as wide as long, and the anterior margin of the eighth tergum straight. Ancylosis morbosella differs in the triangular papillae anales with length equal to width, and the anterior margin of the eighth tergum convex.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

03823958335DFF8F4592FF596B18F95A.taxon	diagnosis	Diagnosis. Ancylosis plumbatella is similar to A. gracilella (Ragonot, 1887). It can be distinguished by the more distinct broad arch-shaped antemedial line and the thin straight postmedial line of the forewing. The male genitalia of A. plumbatella are characterized by the cylindrical gnathos about 1 / 2 length of the uncus, the valva parallel-sided after the sacculus and the U-shaped vinculum rounded on the anterior margin. In A. gracilella, the beak-shaped gnathos is about 1 / 3 length of the uncus, the valva is broadened after the sacculus and the V-shaped vinculum is pointed on the anterior margin. The female genitalia of A. plumbatella are characterized by the triangular papillae anales rounded at apex, and the thin elliptical corpus bursae with numerous small cone-shaped spines. In A. gracilella, the triangular papillae anales are pointed at apex, and the corpus bursae is thin at posterior 1 / 3, broadened in anterior 2 / 3, and has larger cone-shaped spines. We have also discussed the differences between this species and A. byuni sp. nov. above.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

03823958335FFF8C4592FDEC6CB2FCD1.taxon	diagnosis	Diagnosis. Ancylosis roscidella is similar to A. oblitella (Zeller, 1848) externally, but it is pale in color and antemedial and postmedial lines are indistinct in contrast to A. oblitella. Additional differences between these two species are discussed above. The genitalia of A. roscidella are similar to those of A. bartelella, but the male genitalia are distinguished by the uncus rounded at apex, the gnathos pointed and curved at apex, the valva 6 times as long as wide and the vinculum narrowed anteriorly; in A. bartelella, the uncus is pointed at apex, the gnathos is inflated at apex, the valva is 7 times as long as wide and the vinculum is uniformly wide. In female genitalia, the corpus bursae is longer than the ductus bursae in A. roscidella, but it is shorter than the ductus bursae in A. bartelella.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

03823958335EFF8C4592FC446B06F9CA.taxon	diagnosis	Diagnosis. Ancylosis sabulosella is similar to A. umbrilimbella (Ragonot & Hampson, 1901), but the forewing of A. sabulosella with the antemedial line from the posterior margin reaching 2 / 3 width of the forewing, and A. umbrilimbella forewing with the antemedial line from the posterior margin to the costal margin. The male genitalia are characterized by the uncus with rounded apex, the long gnathos reaching 3 / 4 the length of the uncus, the valva broadened after the sacculus and the vinculum 1.5 times as long as wide with rounded anterior margin. A. umbrilimbella differs in the uncus with pointed apex, the shorter gnathos reaching 1 / 2 the length of the uncus, the valva narrowed after the sacculus and the vinculum equal in length and width with straight anterior margin. The female genitalia are characterized by the cylindrical antrum twice as long as wide, and the corpus bursae rounded anteriorly. In A. umbrilimbella, the funnel-shaped antrum is 1.2 times as long as wide and the corpus bursae is not rounded anteriorly.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.

03823958335EFF934592F9BD6E93FD89.taxon	diagnosis	Diagnosis. Ancylosis xylinella is a large species distinguishable by the forewing having a broad pale yellow costal band (about 1 / 4 width of the forewing) with a downward angle at distal 1 / 3. Antemedial line is same to forewing ground color, indistinct, edged with dark brown on outer side, postmedial line is pale yellow, edged with dark brown on inner side, discal cell is pale yellow mixed with brown and dark brown. The male genitalia of A. xylinella can be distinguished by the uncus with rounded apex, the gnathos with inflated apex and the valva gradually narrowing after the sacculus. The female genitalia of A. xylinella can be distinguished by the short ductus bursae (about 1 / 6 length of corpus bursae) and the elongate large corpus bursae with cone-shaped spines arranged in several longitudinal rows along the length of corpus bursae.	en	Gulzar, Abdukirim, You, Wanxue, Ren, Yingdang, Li, Houhun (2025): The genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ningxia Shapotou Nature Reserves of China.
