This new species is similar to B. wolffi Karsholt & Sinev, 2004 in the male genitalia, but it can be separated from B. wolffi by the membrane above the proximal flange bearing dense spines, and the phallus produced into a small hooked process apically. In B. wolffi, the membrane above the proximal flange bears dense microtrichiae instead of spines, and the phallus produced to a short finger-shaped process distally (Karsholt & Sinev 2004: Fig. 64). Description.Adult (Fig. 13) forewing length 5.5–6.5 mm. Head: Frons yellowish brown intermixed with brown, vertex brown, scales tipped with grayish white. Antenna with scape brown on dorsal surface, tipped with yellowish white partially, yellowish white on ventral surface; pecten brown; flagellum dark brown, ciliated on ventral surface in male, first flagellomere dilated and notched in male. Labial palpus dark brown except some scales tipped with grayish white on outer surface, grayish yellow and flattened on inner surface; second segment grayish white apically, inner surface with a narrow crescent yellowish white spot along dorsal margin; third segment slightly shorter than second, gradually narrowed to pointed apex. Haustellum dark brown. Thorax: Nota and tegula dark brown, part scales tipped with pale gray. Forewing brown, with grayish white tipped pale brown and grayish white scales from near base becoming denser to basal 1/3, forming a grayish white fascia extending from basal 1/3 below costa to dorsum, with dense grayish brown tipped dark brown scales intermixed with grayish white tipped scales on distal 2/3; discocellular and tornal spots ill-defined; fringe brown, intermixed with dark brown scales tipped with grayish white. Hindwing and fringe grayish brown at base, becoming darker to apex. Legs with dorsal surface grayish white; ventral surface dark brown, part scales tipped with grayish white; tibiae grayish white at middle and apex, all tarsomeres grayish white apically. Abdomen: Male genitalia (Fig. 23) with basal 1/4 of uncus broad and subrectangular, distal 3/4 narrower, clavate, nearly parallel-sided, rounded apically, slightly curved ventrad, sparsely setose. Gnathos with posterior margin sub-triangularly produced and with two small denticles medially. Dorsal part of valva with costal process slightly widened from costa upward to middle, then almost uniformly wide to rounded apex, uniformly extending ventrad from costa and sclerotized along outer edge to proximal flange; proximal flange bearing long setae along ventral margin, membrane above proximal flange with dense spines, intermixed with sparse setae. Ventral part of valva with basal half broad, nearly parallel-sided, then narrowed to basal 2/3; distal 1/3 produced to a spine-like process, curving inward, setose; sacculus with basal half sub-oval, then almost uniformly wide to terminal, setose on distal half. Juxta a transverse band. Vinculum a wide band. Phallus slightly longer than valva, curved ventrad, basal 1/3 almost uniformly wide, gradually narrowed medially, distal 1/3 almost uniform, produced to a hooked apical process curving inward toward base; internal sclerite curved near base; anellus bearing cone-like setae before middle. Female unknown. Distribution. China (Chongqing, Guizhou, Sichuan, Yunnan). Etymology. The specific epithet is derived from the Latin hamatus (hooked), and refers to the hooked apical process of the phallus.Published as part of Teng, Kaijian & Wang, Shuxia, 2019, Taxonomic study of the genus Blastobasis Zeller, 1855 (Lepidoptera: Blastobasidae) from China, with descriptions of six new species, pp. 25-46 in Zootaxa 4679 (1) on pages 42-45, DOI: 10.11646/zootaxa.4679.1.2, http://zenodo.org/record/346626

Novel fuzzy logic controllers with self-tuning capability
No full textTwo controllers which extend the PD+I fuzzy logic controller to deal with the plant having time varying nonlinear dynamics are proposed. The adaptation ability of the first self tuning PD+I fuzzy logic controller (STPD+I_31) is achieved by adjusting the output scaling factor automatically thereby contributing to significant improvement in performance. Second controller (STPD+I_9) is the simplified version of STPD+I_31 which is designed under the imposed constraint that allows only minimum number of rules in the rule bases. The proposed controllers are compared with two classical nonlinear controllers: the pole placement self tuning PID controller and sliding mode controller. All the controllers are applied to the two-links revolute robot for the tracking control. The tracking performance of STPD+I_31 and STPD+I_9 are much better than the pole placement self tuning PID controller during high speed motions while the performance are comparable at low and medium speed. In addition, STPD+I_31 and STPD+I_9 outperform sliding mode controller using same method of comparison study
