    Musa x formobisiana (Musaceae), a new interspecific hybrid Banana

    No full text
    Taiwan is near the northern limit of distribution of Musaceae. To understand the genetics and extent of genetic diversity in wild bananas in Taiwan, artificial hybrids between Musa itinerans var. formosana and M. balbisiana Colla, here named Musa x formobisiana H.-L. Chiu, C.-T. Shii & T.-Y.A. Yang hybrid nov., were produced. Photos and a comparison of the characteristics of Musa x formobisiana with the parent species are provided. Voucher specimens are at the Herbarium, National Museum of Natural Science, Taiwan (TNM)

    Enicospilus fusiformis Chiu, 1954 Fig. 31 Enicospilus fusiformis Chiu, 1954: 27; holotype ♀ from Taiwan (TARI). Diagnosis Interocellar area reddish brown; clypeus weakly convex, ventral margin subacute; mandible twisted ca 20°, outer surface without a diagonal setose groove; fore wing fenestra with only distal sclerite present, vein 1m-cu&M centrally angled and broadened; metasoma from T5 onwards black. Material examined VIETNAM • 1 ♀; Vinh Phuc Province, Tam Dao NP; 20 Apr. 1996; Y. Okushima leg.; light trap; OMNH • 1 ♂; same collection data as for preceding; 20 May 1996; light trap; OMNH • 1 ♀; Thai Nguyen Province, Dai Tu, Cat Ne; 15–20 Nov. 2006; Khuat D.L. leg.; Malaise trap; IEBR. Remarks In comparison with the specimens examined by Gauld & Mitchell (1981), Vietnamese specimens have shorter fore wings (12.0– 14.7 mm vs 15.0–17.0 mm), greater ICI (0.62–0.74 vs 0.53–0.58), and smaller AI (0.53–0.64 vs 0.82–1.13). Distribution Previously known from Australia, China (including Taiwan), and India (Yu et al. 2016). These are the first records of this species from Vietnam.Published as part of Pham, Nhi Thi, Pham, Phu Van, Matsumoto, Rikio, Shimizu, So & Broad, Gavin R., 2023, A review of the genus Enicospilus Stephens (Ichneumonidae: Ophioninae) from Vietnam, with descriptions of ten new species, pp. 1-151 in European Journal of Taxonomy 873 (1) on page 61, DOI: 10.5852/ejt.2023.873.2133, http://zenodo.org/record/803802

    Hypercube + Rubik’s Cube + Music = HyperCubeHarmonic

    Musical chords and chord relations can be described through mathematics. Abstract permutations can be visualized through the Rubik’s cube, born as a pedagogical device [7,21]. Permutations of notes can also be heard through the CubeHarmonic, a novel musical instru- ment. Here, we summarize the basic ideas and the state of the art of the physical implementation of CubeHarmonic, discussing its conceptual lift- ing up to the fourth dimension, with the HyperCubeHarmonic (HCH). We present the basics of the hypercube theory and of the 4-dimensional Rubik’s cube, investigating its potential for musical applications. To gain intuition about HCH complexity, we present two practical implementa- tions of HCH based on the three-dimensional development of the hyper- cube. The first requires a laptop and no other devices; the second involves a physical Rubik’s cube enhanced through augmented and virtual reality and a specifically-designed mobile app. HCH, as an augmented musical instrument, opens new scenarios for STEAM teaching and performing, allowing us to hear the “sound of multiple dimensions.
