Fujimacia cornutiprocera Qi & Li 2019, sp. nov.

Mujie Qi, Xiaofei Yang, genitalia slide No. QMJ17002. Paratypes: 1 ♀, same data as holotype, genitalia slide No. QMJ17006; 1 ³, 2 ♀, Yadong (29.33°N, 95.34°E), Mêdog County, 833 m, 2-VIII-2018, leg. Mujie Qi, genitalia slide Nos. QMJ18016 ³, QMJ18017 ♀, QMJ18021 ♀. Diagnosis. This species is similar to F. bicoloralis in the male and female genitalia, but it can be distinguished in the male genitalia by the uncus slightly concave in middle laterally, the horn-shaped basolateral process of the uncus, the valva setose before apical process and on distal 1/3 of the ventral area; and in the female genitalia by the antrum wider than colliculum and about 2 times its length. In F. bicoloralis, the uncus is convex laterodistally, the rather slim basolateral process of the uncus is finger-shaped, and the valva has sparse setae on distal 1/5–1/6 of the ventral area (Fig. 9); the antrum is slenderer than the colliculum and about 2.5 times as long as the colliculum (Fig. 14). The new species is also similar to F. longispinosa sp. nov. and the differences between them are stated under F. longispinosa sp. nov. Description. Adult (Fig. 2). Wingspan 22.0– 23.5mm. Frons and vertex yellowish-brown. Labial palpus yellowish-brown; first segment about 1/4 length of second; second segment upturned; third segment slightly porrect, as long as first; female with first and third segments each about 1/3 length of second. Maxillary palpus tiny, concolorous with labial palpus. Male antenna with scape ovate, flagellum ciliate ventrally; female antenna simple. Patagium and tegula pale yellowish-brown. Forewing pale yellowish-brown, basal area brown; terminal area fuscous or dark reddish-brown except for apex brown below costa; costal margin fuscous interrupted by brown spots except terminal area brown; antemedial line invisible, outer edge of basal area reddish brown and sinuous strongly, from basal 1/4 of costa to basal 1/3 of dorsum; postmedial line inconspicuous, incurved slightly, inner edge of terminal area from distal 2/5 of costa to distal 1/8 of dorsum sinuous; median area with scattered fuscous scales, distal discoidal stigma fuscous, rather large; cilia fuscous except brown at base in male, fuscous in female. Hindwing concolorous with median area of forewing except basal area, with scattered fuscous and reddish brown scales; antemedial line brown, sinuous, edged with fuscous scales; postmedial line brown, edged with reddish brown and fuscous scales; cilia concolorous with forewing. Foreleg fuscous except brown at tip of femur, on distal half of tibia and at apex of each tarsomere; midleg with femur and basal 1/3 of tibia fuscous, remaining part yellowish-brown; hindleg yellowish-brown, femur with scattered fuscous scales. Male genitalia (Fig. 10). Uncus conical, setose dorsally on distal half, rounded at apex, laterally slightly concave in middle; basolateral process horn-shaped, pointed at apex. Gnathos with lateral arms slightly bulged medially; distal process oblong, with an upturned hook at apex, about 2/3 length of uncus. Valva broad basally, gradually narrowed towards apex, setose before apical process and on distal 1/3 of ventral area, with transverse ridge extending from base of costa to distal 1/3 of ventral margin of valva; sacculus about 2/3 length of valva, basal 2/3 cylindrical, distal 1/3 rod-like; apical process thorn-shaped, gradually sharpening towards apex, about 2 times as long as hook of gnathos. Juxta oval, slightly concave in V shape posteriorly. Saccus rounded, about 2/3 length of juxta. Phallus with basal bulb oval, nearly as long as distal part, distal sclerite curved ventrally; cornutus about 2/3 length of phallus. Female genitalia (Fig. 15). Papillae anales with basal half ovate, narrow and parallel from 1/2 to basal 3/4, distal 1/4 dilated. Apophyses anteriores long, sinuous, about 1.7 times as long as apophyses posteriores. Antrum about twice as long as apophyses posteriores, slightly convex laterally. Colliculum about half as long as antrum. Ductus bursae membranous, anterior 1/4 scobinate on inner surface, posterior 3/4 slightly wrinkled. Corpus bursae rounded, about 1/10 length of ductus bursae; signum rounded, with long thorn medially, with numerous spinules becoming smaller from center to edge. Distribution. China (Tibet). Etymology. The specific name is derived from the Latin cornutus (horn-shaped) and procerus (projecting), in reference to the horn-shaped process at base of uncus.Published as part of Qi, Mujie & Li, Houhun, 2019, Taxonomic study of the genus Fujimacia Marumo, 1939 (Lepidoptera: Pyralidae) in China, with descriptions of four new species, pp. 171-181 in Zootaxa 4661 (1) on pages 173-175, DOI: 10.11646/zootaxa.4661.1.9, http://zenodo.org/record/337863
Newton’s method for computing the nearest correlation matrix with a simple upper bound
No full textThe standard nearest correlation matrix can be efficiently computed by exploiting a recent development of Newton’s method (Qi and Sun in SIAM J. Matrix Anal. Appl. 28:360–385, 2006). Two key mathematical properties, that ensure the efficiency of the method, are the strong semismoothness of the projection operator onto the positive semidefinite cone and constraint nondegeneracy at every feasible point. In the case where a simple upper bound is enforced in the nearest correlation matrix in order to improve its condition number, it is shown, among other things, that constraint nondegeneracy does not always hold, meaning Newton’s method may lose its quadratic convergence. Despite this, the numerical results show that Newton’s method is still extremely efficient even for large scale problems. Through regularization, the developed method is applied to semidefinite programming problems with simple bounds
