Notes on Some aspects of unsteady hydraulics of watercourses
Full text linkThese notes are prepared for the support of projects and courses about open channel flows in watercourses at Aalborg University. It is thought as continuation of, “Brorsen, Michael ; Larsen, Torben. / Lærebog i Hydraulik” (Compendium in Hydraulics) which is available in Danish. The intention of the notes is to prepare the reader for the use of the advanced commercial computer models available for solving hydraulic problems in watercourses and open channels. It is definitely not the intention to present the complete hydraulic theory behind those computer models. The specific details can be found in the literature and in the respective reference manuals for the computer models.The notes are under continuous development and any comments are welcome. Please send comments to Torben Larsen, Aalborg University, [email protected]

The genus Hyda (type species H. micacea Mabille, 1889, a junior synonym of Sarangesa tertullianus Fabricius, 1793) is a junior homonym of Hyda Walker, 1854 (a moth genus in Arctiinae). Conventionally placed in Sarangesa: Holland (1896) [subgenus Hyda] Aurivillius [in Seitz] (1925); Evans (1937); Larsen (2005).Published as part of Larsen, Torben B. & Congdon, Colin E., 2011, Triskelionia, a new African genus of the Celaenorrhinini (Lepidoptera: Hesperiidae) and the promotion of T. compacta to species-status., pp. 53-58 in Zootaxa 2931 on page 54, DOI: 10.5281/zenodo.27805

Ceratricula semilutea subsp. indeterminabilis Strand 1912, comb. nov.
No full textCeratricula semilutea indeterminabilis (Strand, 1912) comb. nov., stat. rev. Ceratrichia indeterminabilis Strand, 1912. Archiv für Naturgeschichte 78 (A. 9.): 110 (92–111). Type locality. Cameroun: “Alen”. Type depository: not traced.downgraded to junior synonym of C. semilutea by Evans (1937). This is generally a larger subspecies (13.5–15.0 mm) that differs from the nominate in the stronger white forewing spotting, interposed between the two smaller subspecies. Normally there is an upper cell-spot, three subapical spots that are in line, and spots in 3, 2, and 1 b, usually much larger than in the other subspecies. The hindwing has a broadly black costa and the yellow area is of a more insipid tone than in the nominate. The forewing underside has more subapical ochreous scaling than the nominate, though less than in ssp. congdoni. The hindwing underside shares the tone of yellowish-beige, lighter than on the upperside, and much less yellow than in the nominate. There is a brown patch at the end of the cell, another at the middle of space 1 b, and one at the tornal angle (see figure 4). The hindwing underside is basically similar to ssp. congdoni; these two subspecies appear more closely related to each other than either is to ssp. semilutea. There are records from the forests of Cameroun, Gabon, the Central African Republic, and westernmost parts of the Democratic Republic of Congo (Kinshasa), it must be in the Congo Republic as well. No Angolan material was located. There seems to be some degree of transition to ssp. congdoni between the Central African Republic and Kisangani, but hardly any material is available from that area.Published as part of Larsen, Torben B., 2013, Ceratricula and Flandria — two new genera of Afrotropical Hesperiidae (Hesperiinae (incertae sedis )) for species currently placed in the genus Ceratrichia Butler, pp. 476-488 in Zootaxa 3666 (4) on page 483, DOI: 10.11646/zootaxa.3666.4.4, http://zenodo.org/record/22385
