No full textReticulaphis septica Yeh & Hsu sp. nov. (Figs. 14, 15) Apterous adult female. A small species, body ovate, black with purplish-blue burnish, marginal setae short and stout, with fan-shaped apices, body margin without waxy powder. Body 0.47–0.53 mm long, about 1.33 (1.27–1.41) times as long as wide, widest part at position corresponding to front legs, 2 shrunken furrows from prosomal margin to submargin at positions corresponding to front and middle legs. Antennae much shorter than space between them, L-shaped bend without segmentation, long arm about 25–37.5 μm with 1 minute rhinaria and 1 terminal seta near apex. Eyes submarginal, with 2 facets (some individuals with 3 facets). Prosoma distinctly reticulated with pale thin lines, dorsum with 3 deep transverse ridges on median area and several rounded areas surrounding it; 5 pairs of minute setae on central axis of prosoma, 1 st pair between eyes; prosoma with 10 pairs of marginal setae, all marginal setae short and stout, almost as long as long arm of antennae, with fan-shaped or serrated apices. Legs short, hind legs somewhat exposed; front and middle tibiae shorter than femora, hind tibiae equal to or shorter than femora; tarsi narrower than tibia, longer than wide; 1 long fine capitate seta on dorsal front tarsi, 2 such setae on middle and hind tarsi. Abdominal tergites II–VII about 140–157.5 μm wide and 57.5–67.5 μm long, also reticulated, without siphunculi and with 6 pairs minute setae along converging sides of tergites, only base tubercles visible. Abdominal tergite VIII an equilateral triangle, about 75–85 μm wide and 30–40 μm long, with 2 blunt, stout apical setae, nearly as long as marginal setae. Cauda knobbed, constricted basally. Subanal plate deeply bilobed, each lobe with 4–6 setae. Material examined. Holotype, Taiwan: Dashe Township, Kaohsiung Co., on Ficus septica, 9 -iv- 2006, H.T. Yeh (# 476). Paratypes, Taiwan: Luodong Township, Ilan Co., 28 -iii-2006, 22 apterous adults from F. septica (on 2 microscope slides) (Y.F. Chen # 469); Baihe Township, Tainan Co., 8 -iv-2007, 12 apterous adults from F. septica (C.C. Ko # 596); Da-an District, Taipei City, 21 -iv-2007, 14 apterous adults from F. septica (T.C. Hsu # 600); Dashe Township, Kaohsiung Co., 27 -v-2007, 48 apterous adults from F. septica (on 7 microscope slides) (H.T. Yeh # 608) (ANIC, BMNH, CDFA, NMNS, TARIIC, USNM). Etymology. The specific name ‘ septica ’ is derived from the associated host plant, F. s e p t i c a. Remarks. This species can be found in suburbs or hills, and feeds year round on new to mature leaves. The population density can be very high on mature leaves, and often causes serious sooty molds. This species differs from R. mirabilis in the pair of tiny setae between the eyes on the dorsal prosoma, and the comparatively stout marginal setae with distinctly fan-shaped apices of the prosoma; and differs from R. asymmetrica by the ovate body shape, and the pleural regions of prosoma not being expanded.Published as part of Yeh, Hsin-Ting, Ko, Chiun-Cheng & Hsu, Tung-Ching, 2008, Review of the East-Asian genus Reticulaphis (Aphididae: Hormaphidinae), with two new species, pp. 34-48 in Zootaxa 1782 on pages 45-46, DOI: 10.5281/zenodo.27431

Body 0.51–0.66 mm long, about 1.45 (1.40–1.54) times as long as wide. Antennae beneath head, shorter than space between them, L-shaped bend without segmentation, long arm about 37.5–45 μm with 2 minute rhinaria and 1 terminal seta near apex. Eyes submarginal, with 3 facets, one located more laterally and ventrally. Prosoma distinctly reticulated with pale thin lines, dorsum with 4 well-defined swellings, largest one semi-oval, corresponding to position of head+prothorax, following two rectangular, corresponding to positions of meso- and metathorax, smallest at position of abdominal tergite I, but sometimes indistinct; 5 pairs of minute setae on central axis of prosoma, but not obvious, 1st pair between eyes; prosoma with 10 pairs of marginal or submarginal setae, some setae curved to rear, all setae long, with acute, blunt, or frayed apices. Legs well developed, front and middle legs concealed under body, hind legs somewhat exposed; front and middle tibiae shorter than or equal to femora, but hind tibiae longer than or equal to femora; tarsi narrower than tibiae, longer than wide; 1 long fine capitate seta on dorsal front tarsi, 2 such setae on middle and hind tarsi. Abdominal tergites II–VII about 170–200 μm wide and 57.5–75 μm long, also reticulated, without siphunculi and with 6 pairs minute setae along converging sides of tergites. Abdominal tergite VIII an equilateral triangle, about 90–100 μm wide and 40–50 μm long, with 4 setae, central two much longer than outer two. Cauda knobbed, constricted basally.

Linking motion-induced blindness to perceptual filling-in
Full text link"Motion-induced blindness" and "perceptual filing-in" are two phenomena in which perceptually salient stimuli repeatedly disappear and reappear after prolonged viewing. Despite the many similarities between MIB and PFI, two differences suggest that they could be unrelated phenomena: (1) An area surrounded by background stimuli can be perceived to disappear completely in PFI but not in MIB and (2) high contrast stimuli are perceived to disappear less easily in PFI but, remarkably enough, more easily in MIB. In this article we show that the apparent differences between MIB and PFI disappear when eccentricity, contrast, and perceptual grouping are taken into account and that both are most likely caused by the same underlying mechanism
