Saccadic eye movements in the dark while performing an automatized sequential high-speed sensorimotor task
Foerster RM, Carbone E, Koesling H, Schneider WX. Saccadic eye movements in the dark while performing an automatized sequential high-speed sensorimotor task. Journal of Vision. 2012;12(2)(8):1-15.Saccades during object-related everyday tasks select visual information to guide hand movements. Nevertheless, humans can perform such a task in the dark provided it was automatized beforehand. It is largely unknown whether and how saccades are executed in this case. Recently, a long-term memory (LTM)-based direct control mode of attention during the execution of well-learned sensorimotor tasks, which predicts task-relevant saccades in the dark, was proposed (R. M. Foerster, E. Carbone, H. Koesling, & W. X. Schneider, 2011). In the present study, participants performed an automatized speed-stacking task in the dark and in the light while their eye movements were recorded. Speed stacking is a sequential high-speed sensorimotor object manipulation task. Results demonstrated that participants indeed made systematic eye movements in the dark. Saccadic scan paths and the number of fixations were highly similar across illumination conditions, while fixation rates were lower and fixation durations were longer in the dark. Importantly, the eye reached a location ahead of the hands even in the dark. Finally, neither eye–hand dynamics nor saccade accuracy correlated with hand movement durations in the dark. Results support the hypothesis of an LTM-based mode of attention selection during the execution of automatized sequential high-speed sensorimotor tasks
Asobara Foerster 1863
Genus Asobara Foerster, 1863 Diagnosis Mandibles large, simple, tridentate. Upper tooth normally wide; median tooth usually rather narrow and long (sometimes wide and short); lower tooth wide and with small angle ventrodistally. Anterior tentorial pits short, remaining far from edge of eyes. First flagellar segment distinctly shorter than 2 nd segment or of similar length. Mesoscutum with mesoscutal pit usually present; notauli usually present only in anterior part of mesoscutum (sometimes reaching mesoscutal pit); precoxal sulcus always present; propodeum with different types of sculpture and sometimes with areola. In fore wing, vein 3-SR longer than 2-SR; m-cu antefurcal or (sometimes) interstitial; first subdiscal cell open, 2CU subinterstitial, hind wing with m-cu absent, r-m and M+CU much shorter than 1M or cu-a absent. Ovipositor sheath sparsely setose but glabrous basally. Hosts Larvae of Drosophilidae and Tephritidae. Excluded species According to the key by Fischer (1963) Phaenocarpa cristata Szépligeti, 1915 from the Democratic Republic of the Congo should have an open first subdiscal cell of the fore wing and, therefore, should be included in Asobara Foerster, 1863. The type series was deposited in the former Naturhistorisches Museum Hamburg (now Biozentrum Grindel und Zoologisches Museum), but could not be found and was most likely lost during the 2 nd World War. The too short description (ovipositor sheath about as long as body and body length 5 mm) makes it likely that it concerns a species of Phaenocarpa Foerster, 1862, which is excluded from this revision.Published as part of Peris-Felipo, Francisco Javier, Achterberg, Cornelis Van & Belokobylskij, Sergey A., 2019, Revision of the Afrotropical Asobara Foerster, 1863 (Hymenoptera: Braconidae: Alysiinae), with the descriptions of twenty five new species, pp. 1-146 in European Journal of Taxonomy 557 on pages 2-3, DOI: 10.5852/ejt.2019.557, http://zenodo.org/record/346782

Orthocentrinae Foerster 1869
Subfamily Orthocentrinae Foerster, 1869 Orthocentrinae is a world-wide subfamily that includes small and moderate-sized ichneumonids. They are parasitoids of primitive Diptera, mainly of the superfamily Sciaroidea. There are 29 extant genera and over 500 species (Humala, 2019). Fossil Orthocentrinae are found in Green River (Cockerell, 1919, 1920, 1921, 1941), Bembridge marls (Khalaim, 2014), Florissant (Brues, 1906, 1910) and other Cenozoic deposits. In Baltic amber, two species are known from the fossil genus Scutellator Kasparyan & Humala, 1995: S. macrommatu Kasparyan & Humala, 1995 and S. spinatorius Kasparyan & Humala, 1995. One species, Plectiscidea vetusta Kasparyan & Humala, 1995, was described in the Recent genus Plectiscidea Viereck, 1914. One specimen on Orthocentrinae with unclear taxonomic position was found in the KAM collection.Published as part of Manukyan, Andranik R. & Zhindarev, Leonid A., 2021, Fossil Darwin wasps (Hymenoptera: Ichneumonidae) from Baltic amber, pp. 637-647 in Palaeoentomology 4 (6) on page 639, DOI: 10.11646/palaeoentomology.4.6.13, http://zenodo.org/record/577851
Epimicta Foerster 1862
Epimicta Foerster, 1862 Epimicta Foerster, 1862: 225 –288 (Type species: Alysia (Dacnusa) marginalis Haliday, 1839); Wharton, 1994: 633–635; Tobias, 1998: 312; Kula, 2005: 78–83. Type species: Alysia (Dacnusa) marginalis Haliday, 1839. Diagnosis. Head short and transverse; antenna thick, third antennal segment longer than fourth segment; frons short; face punctuate; mandible broad, with four teeth, first tooth wide and obtuse, second tooth nearly equilateral triangle and pointed, third tooth lobe-shaped and round, fourth tooth small and located along ventral margin; pronotum with small pronope; notauli deep and crenulate; antescutellar depression deep, long and with several strongly longitudinally short carinae; precoxal sulcus complete, running along entire length of mesopleuron and crenulate-rugulose; metanotum with an well-developed dorsal flange; propodeum areolate rugose; metapleuron rugose to crenulate- rugose, setiferous (Fig. 5); vein r of fore wing arising basally midpoint of pterostigma, vein 1 - SR+M more or less weakly S-shaped, vein m-cu antefurcal; vein m-cu of hind wing absent; hind coxa relatively small; hind femur slender; claw simple; metasomal tergites mainly setose, second and usually part of third tergites sculptured (Fig. 6). Remarks: As noted by Nixon (1943), Griffiths (1964), Riegel (1982) and Wharton (1994 ) Epimicta Foerster is close to Trachionus Haliday. The most distinct difference between these two genera is that Trachionus has a more complete carapace-like metasoma. Distribution.
