Some modular varieties of low dimension II
No full textThe paper extends results obtained by Frieder Hermann and Eberhard Freitag about a six-dimensional modular variety related to the orthogonal group of signature (2.6). The ring of modular forms of this variety turns out to be a weighted polynomial ring in 7 variables. © 2007 Elsevier Inc. All rights reserved

This female was collected at the type locality of Hydraena pseudopalawanensis. Although it is most likely that this female belongs to H. pseudopalawanensis, we refrain from including it in the type series (for explanation, see below). Diagnosis. Body 1.15–1.20 mm long. Colour and habitus as in Hydraena palawanensis (Fig. 10). Aedeagus (Figs. 23 a–c) agrees in several principal characters with that of H. palawanensis, but differs in numerous other conspicuous characters: e.g., apical half of main piece more strongly curved (ventral/dorsal view), right margin of main piece without conspicuous emargination near insertion of paramere; presence of one dorsal seta; left paramere moderately long, slender, apically with five moderately long setae; right paramere ventromedially with a longitudinal row of ca. four moderately long setae. We were not able to distinguish females of H. pseudopalawanensis and H. palawanensis reliably. Since both species occur in the same habitat, we were not able to identify all females from central Palawan (deposited in the NMW) properly: 1 Ψ: “ PHIL.: Palawan, P.

Distribution (Fig. 31). Hydraena pseudopalawanensis is obviously confined to the island of Palawan, where it is not uncommon. Ecology. Hydraena pseudopalawanensis resembles H. palawanensis even in ecological terms. The habitats include rather undisturbed (e.g. CR 1) and to some extent anthropogenically influenced rural areas (e.g. CR 3; Freitag 2005), suggesting a rather high ecological potency. Besides numerous specimens caught in emergence traps, some individuals were manually collected together with H. palawanensis in the same habitat (detritus interstitial). Etymology. The species is named in reference to its close relationships with Hydraena palawanensis.Published as part of Freitag, Hendrik & Jäch, Manfred A., 2007, Revision of the species of Hydraena Kugelann (Coleoptera: Hydraenidae) from Palawan and Busuanga, with descriptions of eleven new species, and redescription of Hydraena (Hydraenopsis) scabra d'Orchymont, 1925, pp. 1-44 in Zootaxa 1431 on pages 29-31, DOI: 10.5281/zenodo.17579

Consistency of bootstrap procedures for the nonparametric assessment of noninferiority with random censorship
No full textIn this paper we consider general Hadamard differentiable functionals φ(ΛR, ΛT )o f the cumulative hazard functions of two samples of randomly right censored data, which can be used for the nonparametric assessment of noninferiority. We prove the consistency of various bootstrap procedures as suggested in Freitag et al. (1) for the practical implementation of tests for this problem

In most characters very similar to Ancyronyx tobada, except for the following: generally dark brown dorsally; paler brown areas limited to lateral portion of head, small areas at anterior and anterolateral margins of pronotum and apex of terminal abdominal segment. Entire ventral side pale. Dorsal tubercles moderately elevated, lateral protuberances distinctly protruding. Head distinctly tapering anteriad, widest at posterior 0.2. Abdominal segments distinctly, protuberantly elevated in posterior portions; posterior abdominal segments I–VIII with four erected setae; segment IX with six of such setae dorsally (Fig. 5 D, these setae are less distinct in the six larval instar); posterolateral protuberances with prominent tubercles and two distinct, moderately long setae (Figs 5 B, C); terminal segment IX (Figs 5 C, D) moderately long, ca. 2.0 times as long as wide; basomedian portion tuberculate; apex distinctly emarginated.Published as part of Freitag, Hendrik & Kodada, Ján, 2017, Larvae of Ancyronyx Erichson, 1847 (Insecta: Coleoptera: Elmidae) from Sulawesi, using DNA sequences for the assignment of the larval stages, pp. 121-130 in Zootaxa 4299 (1) on page 128, DOI: 10.11646/zootaxa.4299.1.6, http://zenodo.org/record/83515
