Miltochrista dongi Huang & Volynkin 2021, sp. n.
No full textMiltochrista dongi Huang & Volynkin, sp. n. (Figs 4, 11) Type material. Holotype (Figs 4, 11): male, “ 3.V.2018, altitude 2100 m, Mt. Dawei, Pingbian Miao Autonomous County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, P. R. China, leg. Si-yao Huang & Tian-tian Yu” [in Chinese], prep. in glycerol by Huang (Coll. SCAU). Diagnosis. Miltochrista dongi sp. n. differs externally from its closest relative M. xihe sp. n. by its smaller size, the narrower forewing, the blackish abdomen (it is dark brown in M. xihe sp. n.), the crimson forewing ground color (it is pale red in M. xihe sp. n.), the presence of a wide blackish patch in the medial part of the forewing from the base to the subterminal area, and the blackish brown hindwing (it is dark brown in M. xihe sp. n.). The wing pattern of M. dongi sp. n. is also somewhat reminiscent of that of Ovipennis (Coccinigripennis) miloslavae (Černý, 2016) from southern Vietnam, but can be readily distinguished from the latter by its larger blackish patch which extends to the wing base (whereas it is not reaching the wing base in O. (C.) miloslavae) and the findamentally different male genitalia structure. The male genital capsule of M. dongi sp. n. is similar to that of M. xihe sp. n., but differs by the valva narrower medially and basally, the conspicuously narrower distal lobe of valva, and the slightly weaker distal saccular process. The aedeagus of the new species is slightly narrower and less elongated in comparison to the genital capsule of M. xihe sp. n. The vesica of M. dongi sp. n. differs clearly from that of M. xihe sp. n. by its narrower main chamber, the absence of spines on the ventral diverticulum, the smaller distal diverticulum bearing a smaller number of spines, and the markedly larger distal plate. Description. External morphology of adults. Forewing length 10 mm in holotype male. Male antenna ciliate, blackish. Legs blackish brown. Head and thorax crimson. Abdomen dark brown. Forewing blackish brown, edged with crimson, with blackish suffusion on veins in the subterminal and terminal areas; cilia crimson. Hindwing blackish brown including cilia. Male genitalia. Uncus long, thin, laterally flattened, curved subapically and apically pointed. Tuba analis moderately broad; scaphium thin, weakly sclerotized; subscaphium presented as setose field. Tegumen short, moderately broad and weakly sclerotized. Juxta shield-like with very deep lower triangular concavity. Valva elongated, narrow, its costal margin convex medially. Costa strongly broadened distally, lacks a distal process. Distal lobe of valva large, with apical moderately sclerotized triangular process. Sacculus with weakly setose dorsal margin. Distal saccular process narrow but robust, elongate, slightly S-like curved and apically blunt. Aedeagus elongated, straight. Vesica broad, with more or less globular main chamber; its ventral diverticulum small, heavily granulated; medial diverticulum broad, globular, bears a series of various-sized robust spines; distal diverticulum short, granulated, bears a cluster of several various-sized spines. Distal plate of vesica broadly triangular, moderately sclerotized. Female unknown. Distribution. The species is known from its type locality only, Mount Dawei in Yunnan Province of China. Etymology. The species is dedicated to Mr. Zhi-wei Dong (Kunming, China), a good friend of the second author who helped him during his trip to Mount Dawei.Published as part of Volynkin, Anton V. & Huang, Si-Yao, 2021, Three new peculiar species of the genus Miltochrista Hübner, [1819] from China (Lepidoptera, Erebidae, Arctiinae), pp. 569-576 in Zootaxa 4970 (3) on page 571, DOI: 10.11646/zootaxa.4970.3.8, http://zenodo.org/record/476688
Analyse des signaux multicomposante à modulation de fréquence linéaire par la transformation de Teager-Huang-Hough
No full textA novel detection approach of linear FM (LFM) signals, with single or multiple components, in the time-frequency plane of Teager-Huang (TH) transform is presented. The detection scheme that combines TH transform and Hough transform is referred to as Teager-Huang-Hough (THH) transform. The input signal is mapped into the time-frequency plane by using TH transform followed by the application of Hough transform to recognize time-frequency components. LFM components are detected and their parameters are estimated from peaks and their locations in the Hough space. Advantages of THH transform over Hough transform of Wigner-Ville distribution (WVD) are: 1) cross-terms free detection and estimation, and 2) good time and frequency resolutions. No assumptions are made about the number of components of the LFM signals and their models. THH transform is illustrated on multicomponent LFM signals in free and noisy environments and the results compared with WVD-Hough and pseudo-WVD-Hough transforms

The female holotype was collected from Yulongxueshan whilst the male paratypes were collected from Ludian, thus the association of male and female requires a confirmation from more material. In a recent expedition made by the first author, specimens of both sexes were collected from both localities. An examination of male and female genitalia proved the original association of male and female to be correct. Distribution.

Carapace and ambulatory legs are bluish-white, chelipeds generally white (Fig. 1 B). Ecology. Like N. guangdongense, the new species inhabits mud burrows near the banks of densely vegetated creeks. The burrows can be as deep as one meter and always have some water at the bottom. Crabs reside in their burrows during the day and are relatively inactive, but are particularly active during hot, humid nights. They are omnivorous, eating dead leaves, earthworms, freshwater shrimps, other crabs, etc. Brooding females have been observed in February. Cannibalism has been observed in captive specimens and may also occur in the wild; large specimens are generally more aggressive. Remarks. Nanhaipotamon zhuhaiense n. sp. can most easily be distinguished from N. guandongense by the live coloration of its carapace, the former being bluish-white (Fig. 1 B) with the latter generally brown (Fig. 1 A). Although the colour of N. guandongense varies slightly from yellowish to orangish-brown, it never attains the colours of N. zhuhaiense n. sp.. As with most Nanhaipotamon species, the carapace, chelipeds and ambulatory legs are extremely similar in form and we could discern no major differences between N. guandongense and N. zhuhaiense n. sp.. The male abdomen of N. guandongense is relatively wider, especially somite 6 (Fig. 4 C), with that of N. zhuhaiense, new species, relatively narrower (Fig. 2 C) (Table 1). The male abdomen of N. guandongense (see Dai 1997: Fig. 9 - 2) is not accurate as it shows a relatively narrower structure. The male abdomen of the holotype is actually proportionately wider (Fig. 4 C). The most significant difference is in the structure of the G 1. While they are superficially similar, that of N. guandongense is more curved, with the inner distal margin distinctly concave (Fig. 5 A–C), while that of N. zhuhaiense n. sp., is relatively straight (Fig 5 D). The form of the terminal segment is also different; in N. zhuhaiense n. sp. the distal part is distinctively more elongated and is bent laterally at almost 90 ° to the vertical (Figs. 3 D, E, 5 D). In N. guandongense, the distal part is shorter and bent obliquely outwards at an angle of about 45 ° to the vertical (Fig. 5 A–C). These differences are consistent and are beyond the variation observed or known for Nanhaipotamon species. TABLE I. Morphological differences among Nanhaipotamon zhuhaiense n. sp. and N. guangdongense Nanhaipotamon zhuhaiense n. sp. has been found only in small numbers from just one site in Zhuhai, where they are sympatric with N. guangdongense. Their population does not appear to be large, and considering their very limited range, we had concerns about their conservation status and therefore restricted our collection of samples. Observations of several more adult and juvenile specimens of N. zhuhaiense n. sp. in the field and laboratory nevertheless confirm the validity of the colour differences observed with N. guangdongense. Although there are reports, based on the basis of their distinctive coloration, that it is present in other areas around of Zhuhai, we have not been able to find them. In all the other areas surveyed around Zhuhai, the only species present is N. guangdongense. This is only the second case of sympatric occurrence of two species in the genus, the other being N. hepingense Dai, 1997, and N. pinghense Dai, 1997. Shih et al. (2011: 437) indicated, however, that there is good evidence that these two species (both described on the basis of only one male each from the same location and collected on the same date) are synonymous. In the case of N. guangdongense and N. zhuhaiense n. sp. the most likely explanation is that the two species were originally allopatric and human activities (land development and moving of agricultural plants and animals) causing part of their ranges to overlap. More thorough surveys will need to be done to determine the precise and original distributions of both species. At the one site where both N. guangdongense and N. zhuhaiense n. sp. are present, the former species is the dominant one. The burrows of these two species have even been found adjacent to each other.Published as part of Huang, Chao, Huang, Jian Rong & Ng, Peter K.
