Type species, Leucacron interruptum Lindner, 1966b, by monotypy. Syn. nov. Acroleuca Lindner, 1966b: 20. Incorrect original spelling. Ptilinoxus interruptum (Lindner). Comb. nov. Leucacron interruptum Lindner, 1966b: 19. HT ♀ [MNHN]: Madagascar: Périnet. The type specimen of L. interruptum was examined and it shows a constriction at the base of the last antennal flagellomere, which Lindner noted in the description and which is an important character for this genus. Lindner compares Leucacron with the Oriental genus Lophoteles Loew but did not make any comments about the new genus following the description of Leucacron in his paper: Ptilinoxus. We consider the antenna of the only specimen of L. interruptum a teratological deformation and regard this genus as a synonym of Ptilinoxus. After examining a large number of Ptilinoxus (which comprises at least two species), we never found a single specimen with the antennal structure as found in the type specimen of L. interruptum. Lindner (1979) listed two males of Lophoteles plumula from the Comoros [MNHN], but these specimens belong to the genus Ptilinoxus. The only records of Lophoteles in the Afrotropical Region are from the Seychelles (Kertész 1914, Woodley 2009).Published as part of Hauser, Martin, Woodley, Norman E. & Fachin, Diego A., 2017, Taxonomic changes in African Stratiomyidae (Diptera) in Zootaxa 4263 (1), DOI: 10.11646/zootaxa.4263.1.3, http://zenodo.org/record/57254

Hypoceromya: Lindner, 1970: 819. Incorrect subsequent spelling. Hypoceromys nigripes (Lindner). Comb. nov. Pachygaster nigripes Lindner, 1938: 28. HT ♂ [IRSNB]: Zaire: Rutshuru. Hypoceromys jamesi (Lindner). Comb. nov. Meristomeringella jamesi Lindner, 1965: 48. HT ♂ [IRSNB]: Sudan: Tori. Hypoxycera simplex Lindner, 1966a: 365. ST 1 ♂ [MRAC]: Zaire: Congo da Lemba; ST 1 ♂ [SMNS]: Zaire: Kinshasa. Syn. nov. Lindner (1935) described the genus Hypoceromys and pointed out the similarity to Psapharomys Grünberg. But because of the more dorsally inserted arista-like last antennal flagellomere, he proposed this new genus. He was not aware of the strong sexual dimorphism in this genus (and in the related Psapharomys, see below). When he described Meristomeringella jamesi (Fig. 5), he compared the new genus with Meristomerinx Enderlein, which is strange because the two genera are not really similar, especially vein R 2+3 arising distinctly distal to crossvein r–m in Meristomerinx and proximal to crossvein r–m in Meristomeringella. Only a year later he described Hypoxycera simplex and mentioned that the last antennal flagellomere was inserted slightly dorsad on the spindle shaped flagellum, which is also the case in Meristomeringella jamesi. We examined the type specimens of both species and concluded that they are conspecific, and that they belong in the genus Hypoceromys. The holotype of Pachygaster nigripes (Fig. 6) has the antennae missing (as mentioned in the original description), but all other characters, such as the wing venation, shape of the head and body shape clearly place this species in the genus Hypoceromys.Published as part of Hauser, Martin, Woodley, Norman E. & Fachin, Diego A., 2017, Taxonomic changes in African Stratiomyidae (Diptera) in Zootaxa 4263 (1), DOI: 10.11646/zootaxa.4263.1.3, http://zenodo.org/record/57254

Microptecticus ambiguus Lindner, 1966b: 13. HT ♀ [MNHN]: Madagascar: Montagne d’Ambre. Microptecticus clarus Lindner, 1968: 2. ST 2 ♀ (stated ♂) [MNHN]: Madagascar: Ranomafana. Syn. nov. Microptecticus magnicornis (Lindner). Comb. nov. Ptecticus magnicornis Lindner, 1936: 39. HT ♀ [SMNS]: Madagascar: Ambositra. Microptecticus nigricoxa (Lindner). Comb. nov. Microchrysa nigricoxa Lindner, 1936: 41. HT ♂ (stated ♀) [SMNS]: Madagascar: Ambositra. Lindner (1936) described the genus Microptecticus with M. dimidiatus as its type species, of which we have examined one of the female syntypes [SMNS]. In the same publication he described Ptecticus magnicornis and Microchrysa nigricoxa. Mason (1997a) stated that M. nigricoxa cannot be kept in the genus Microchrysa and Woodley (2001: 232) listed it under the “unplaced species of Sarginae ”. We have seen the holotypes of both species and they fit well in the concept of the genus Microptecticus, since both have the lower calypter without projecting lobe or at most with very small finger-like projection and M vein strong only distally. Microptecticus ambiguus (Fig. 25) was described as the second species in this genus by Lindner. Shortly thereafter Lindner (1968) described the third species, M. clarus, which he surprisingly compared only to M. dimidiatus and did not mention M. ambiguus at all. We examined the two female syntypes of M. clarus [MNHN] (Fig. 26) and the holotype of M. ambiguus [MNHN] (Fig. 25) and concluded that they are conspecific. We have more than 10 undescribed species of this genus from Madagascar on hand.Published as part of Hauser, Martin, Woodley, Norman E. & Fachin, Diego A., 2017, Taxonomic changes in African Stratiomyidae (Diptera) in Zootaxa 4263 (1), DOI: 10.11646/zootaxa.4263.1.3, http://zenodo.org/record/57254
Infinite Probabilistic Databases
Full text linkProbabilistic databases (PDBs) are used to model uncertainty in data in a quantitative way. In the standard formal framework, PDBs are finite probability spaces over relational database instances. It has been argued convincingly that this is not compatible with an open-world semantics (Ceylan et al., KR 2016) and with application scenarios that are modeled by continuous probability distributions (Dalvi et al., CACM 2009).
We recently introduced a model of PDBs as infinite probability spaces that addresses these issues (Grohe and Lindner, PODS 2019). While that work was mainly concerned with countably infinite probability spaces, our focus here is on uncountable spaces. Such an extension is necessary to model typical continuous probability distributions that appear in many applications. However, an extension beyond countable probability spaces raises nontrivial foundational issues concerned with the measurability of events and queries and ultimately with the question whether queries have a well-defined semantics.
It turns out that so-called finite point processes are the appropriate model from probability theory for dealing with probabilistic databases. This model allows us to construct suitable (uncountable) probability spaces of database instances in a systematic way. Our main technical results are measurability statements for relational algebra queries as well as aggregate queries and Datalog queries

No full textClassical Heroes in the 21st Century
No full textThe study of ancient heroes in film provides an eminent contribution to our understanding of the present by identifying the upheavals, conflicts, crises and resolution strategies that manifest themselves in heroic figures. This volume approaches heroizations by examining political leadership in heroic narratives and the influence of ancient heroes on the construction of modern (super-)heroes. Studies on the negations of the heroic reveal ambivalence, fluidity and legitimization difficulties of the examined figures. Contributions on narrativization and aesthetics address didactic potentials, genre influences, intermedial references and the possible future of (de)heroization in cinematic antiquity.

Gongrosargus Lindner
No full textGenus GONGROSARGUS Lindner Gongrosargus Lindner, 1959: 90. Type species, Gongrosargus stuckenbergi Lindner, 1959, by original designation. Dinosargus Lindner, 1968: 9. Type species, Dinosargus lateritius Lindner, 1968, by monotypy. Syn. nov. Gongrosargus glaucus (Bigot). Afrotropical: Madagascar. Sargus ? glaucus Bigot, 1859: 134. HT? [MNHN, lost]: Madagasgar: Nossi-Bé. Gongrosargus distinguendus Lindner, 1966b: 11. ST 1 ♀ [MNHN]: Madagascar: Andranofotsy; ST 1 ♂ [MRAC], 1 ♀ [SMNS]: Madagascar: Maroantsetra. Syn. nov. The type specimen of Bigot’s Sargus glaucus is lost and the species is treated under Ptecticus in the world catalog (Woodley 2001: 212). From the description, we can place this species clearly in the genus Gongrosargus, because of the description of the thorax, being green with three brown stripes, the scutellum being black at the base and green at the apex, and the hind tarsi having a black basitarsus and the rest being white. This combination of characters is not found in any Ptecticus species from Madagascar, which are all uniformly brown or dull yellow, but fits perfectly with G. distinguendus Lindner 1966, with which we are synonymizing it. We have studied all syntypes of G. distinguendus, the male syntype from MRAC is pictured in Fig. 18. Gongrosargus flavipennis (Macquart). Comb. nov. Sargus flavipennis Macquart, 1838: 200. HT ♂ [MNHN]: Madagascar. Ptecticus flavipes: Loew, 1860: 77. Incorrect subsequent spelling. We have studied the male holotype [MNHN] (Fig. 19), and the species fits well with the concept of Gongrosargus. Gongrosargus lateritius (Lindner). Comb. nov. Dinosargus lateritius Lindner, 1968: 9. HT ♂ [MNHN]: Madagascar: Ivondro. We have studied the male holotype [SMNS] (Fig. 20), and the species fits well with the concept of Gongrosargus. Gongrosargus limbatus (Macquart). Comb. nov. Sargus limbatus Macquart, 1838: 201. HT ♂ [MNHN]: Madagascar. We have studied the male holotype [MNHN] (Fig 21), and the species fits well with the concept of Gongrosargus. This species might be conspecific with G. stuckenbergi, but because of the poor condition of the holotype and we know of several undescribed species close to G. stuckenbergi, we are not formally synonymizing the two species. Gongrosargus pallidus (Macquart). Comb. nov. Sargus pallidus Macquart, 1838: 202. ST 1 ♂ [MNHN], ♀ [MNHN, lost]: Madagascar. Gongrosargus univittatus Lindner, 1966b: 12. ST 1 ♀ [MNHN], 1 ♀ [MRAC]: Madagascar: Famponambo. Syn. nov. Gongrosargus exclamationis Lindner, 1968: 11. ST 1 ♂ [SMNS]: Madagascar: Ivondro, ST 1 ♂ [MNHN]: Madagascar: Fort Dauphin; ST 1 ♂ [MNHN]: Madagascar: Mt. Tsaratanana, Andampy, 750 m. Syn. nov. We have studied the male syntype of Sargus pallidus [MNHN] (Fig. 22), and the species fits well with the concept of Gongrosargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232). Lindner likely never checked Macquart’s types. He considered S. pallidus to belong in “ Chrysochroma ” rather than Gongrosargus, because in Lindner’s collection [SMNS] there are two males of Ptectisargus punctum (Lindner, 1968) misidentified under the name Gongrosargus pallidus. Ptectisargus punctum has the same color pattern (yellow-orange with a black stripe on the thorax) as G. pallidus, but has a clearly different wing venation. When Lindner described G. univittatus (Fig. 23), he did not compare it with G. pallidus, because he did not consider them congeneric. We examined both female syntypes (MNHN, MRAC) [Woodley (2001: 191) stated incorrectly that the “holotype” was in Paris], and they are both conspecific with G. pallidus. Only two years later Lindner (1968) described G. exclamationis (Fig. 24) without comparing it to G. univittatus. We examined two of the three male syntypes of G. exclamationis [MNHN, MRAC] and they are all conspecific with G. pallidus. We have at least three undescribed Gongrosargus on hand, which have a color pattern similar to that of G. pallidus from Madagascar.Published as part of Hauser, Martin, Woodley, Norman E. & Fachin, Diego A., 2017, Taxonomic changes in African Stratiomyidae (Diptera) in Zootaxa 4263 (1), DOI: 10.11646/zootaxa.4263.1.3, http://zenodo.org/record/57254
Ptectisargus Lindner
No full textGenus PTECTISARGUS Lindner Ptectisargus Lindner, 1968: 3. Type species, Ptectisargus lucidus Lindner, 1968, by monotypy. Ptectisargus abditus (Lindner). Comb. nov. Ptecticus abditus Lindner, 1936: 37. HT ♀ [SMNS]: Madagascar: Bekily. Chrysochroma laetum Lindner. 1966b: 7. HT ♂ [MNHN]: Madagascar: Sakaraha. Syn. nov. Ptectisargus lucidus Lindner, 1968: 3. ST 4 ♂, 1 ♀ [MNHN]; 1 ♂, 1 ♀ [SMNS]: Madagascar: Bekily. Syn. nov. We examined the female holotype of Ptecticus abditus [SMNS] (Fig. 27), the male holotype of Chrysochroma laetum [MNHN], and two male syntypes of Ptectisargus lucidus [SMNS, MNHN] (Fig. 28), and we consider all of them conspecific. Ptectisargus brunneus (Lindner). Comb. nov. Ptecticus brunneus Lindner, 1936: 38. HT ♀ [SMNS]: Madagascar: Andreba. We have studied the female holotype [SMNS], and the species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230). Ptectisargus cingulatum (Lindner). Comb. nov. Chrysochroma cingulatum Lindner, 1968: 5. HT ♀ [MNHN]: Madagascar: Mt. Tsaratapana, 1400 m. We have studied the female holotype [MNHN], and the species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230). Ptectisargus flavifrons (Lindner). Comb. nov. Chrysochroma flavifrons Lindner, 1968: 6. HT ♀ [MNHN]: Madagascar: Ranomafana. We examined the female holotype of Chrysochroma flavifrons [MNHN] and this species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231). Ptectisargus flavomarginatus (Loew). Comb. nov. Chrysonotus flavomarginatus Loew, 1857: 263. ST ♀ [NHRS]: Mauritius. We did not examine the type of this species, but the description by Loew fits specimens collected in Madagascar very well. The narrow elongated abdomen, lower calypter with a very elongated projection and the color pattern place this species in the genus Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231). Ptectisargus gracilipes (Lindner). Comb. nov. Ptecticus gracilipes Lindner, 1936: 40. HT ♀ [SMNS]: Madagascar: Andreba. We examined the female holotype of Ptecticus gracilipes [SMNS] and this species fits well with the concept of Ptectisargus. Ptectisargus keiseri (Lindner). Comb. nov. Chrysochroma keiseri Lindner, 1966b: 6. HT ♂ [MNHN]: Madagascar: Montagne d’Ambre. We examined the male holotype of C. keiseri [MNHN] and this species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231). The type series of Ptectisargus lindneri James is mixed and the male “ Allotype ” [BMNH] is conspecific with P. keiseri, while the female holotype [BMNH] is a different species. The female holotype is from the dry SW of Madagascar, while the male is from nearly the opposite corner of Madagascar, from the NE, which has a very different climate, and therefore it is not a surprise that the two specimens belong to different species. The holotype of P. lindneri has dark brown wing veins, a brown scutellum and the hind tibia being dark brown on the basal third and white on the apical 2/3 and the hind tarsi are dark brown, while P. keiseri has orange brown wing veins, a green metallic scutellum and the hind legs all light brown. Ptectisargus longestylum (Lindner). Comb. nov. Chrysochroma longestylum Lindner, 1966b: 8. ST 1 ♂ [MNHN], 1 ♂ [MRAC]: Madagascar: Ahitsitondrona. We examined both male syntypes of C. longestylum [MNHN, MRAC] and this species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231). Ptectisargus punctum (Lindner). Comb. nov. Chrysochroma punctum Lindner, 1968: 6. HT ♂ (stated ♀) [MNHN]: Madagascar: Rogez, Forêt Côte Est. We examined the male holotype of C. punctum [MNHN] and this species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232). Ptectisargus ranohira (Woodley). Comb. nov. Chrysochroma ptecticoides Lindner, 1966b: 5. ST 2 ♂, 1 ♀ [MNHN, NMB, SMNS]: Madagascar: Ambato-Boeni and Ranohira. Preoccupied, primary homonym of Chrysochroma ptecticoides Lindner, 1935. Chrysochroma ranohira Woodley 2001: 232. New name for Chrysochroma ptecticoides Lindner, 1966b. We examined a male syntype of C. ptecticoides [MNHN] and a female syntype [SMNS] and this species fits well into the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232). Ptectisargus unicolor (Lindner). Comb. nov. Chrysochroma unicolor Lindner, 1968: 7. HT ♀ [MNHN]: Madagascar: Ivondro. We examined the female holotype of C. unicolor [MNHN] (Fig. 32) and this species fits well with the concept of Ptectisargus. The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232).Published as part of Hauser, Martin, Woodley, Norman E. & Fachin, Diego A., 2017, Taxonomic changes in African Stratiomyidae (Diptera) in Zootaxa 4263 (1), DOI: 10.11646/zootaxa.4263.1.3, http://zenodo.org/record/57254
