(Lepidoptera: Pyralidae) from Taiwan. From 2009 to 2016, a biology study was conducted on population dynamics and embryonic development. Spring season is the peak of the eclosion of overwintering larvae or pupae. The average longevity of adult was 14.8 ± 6.2 days (N = 174), the average number of eggs laid was 259 ± 3 eggs/moth (N = 2), the hatching rate of eggs was 95.4% (N = 262), and the average hatching time of eggs was 99.6 ± 18.6 hours (N = 68). The average body length of males was 5.64 mm ± 0.91 mm (N = 30), and the average body length of females was 6.28 mm ± 0.84 mm (N = 30). This finding indicates that female snout moths are larger than males (Global R = 0.058, P = 0.012). The snout moth eclosion rate was 16.9 moths/100 pods in the first year (2010/2011, N = 2,224 pods) and 10.9 moths/100 pods in the second year (2014/2015, N = 6,382 pods). The pod borer rate was 31.8% (N = 707) and the seed borer rate was 41.2% (N = 3,628) in the first year, whereas the pod borer rate was 76.2% (N = 6,382) in the second year.展开更多

The new genus is monotypical, with Parathrausta internervalis sp.n. its type species. The adults of the type species, the male genitalia, the female genitalia and the tympanal organs are described and figured. The new genus is recognized as related by characters in the male and female genitalia with genera in the tribes Steniini Guine, 1854 and Nomophilini Kuznetzov & Stekolnikov, 1979, namely with Bradina Lederer, 1863, Perisyntrocha Meyrick, 1894, Diathrausta Lederer, 1863, Diasemiopsis Munroe, 1957, Diasemiodes Munroe, 1957 and with the genera in the Duponchelia Zeller, 1847 group comprising Duponchelia Zeller, 1847, Penestola Mschler, 1890, Tatobotys Butler, 1880 and Hymenoptychis Zeller, 1852. The character states differentiating the new genus from the comparative genera are discussed. Potential autapomorphies of the new genus are listed. The tribal assignment of the new genus to the Nomophilini Kuznetzov & Stekolnikov, 1979 based on morphological characters is discussed. The support of the tribal and cladistic assignment of the new genus as a sister clade to Diathrausta Lederer, 1863 based phylogenetic analyses (NJ, MP and ML) is shown. An unusually strong genetic divergence of the genus in the COI segment of the mt-DNA based on the Tamura-Nei distance measure from the morphologically related genera is recognized and addressed.展开更多

Phylogenetic analyses based on the mitochondrial 12 S, 16 S and CO1 gene sequences suggested that the new taxon was distinctly separated from its congeners and closed to M. mixtura and M. okinavensis. Morphologically, the new species could be identified from its congeners except M. mixtura by several characters:(1) rudimentary webs on toe base;(2) absence of disks and dorsal median longitudinal grooves on finger tips;(3) presence of disks and dorsal median longitudinal grooves on toe tips. As well, the new species could be identified from topotype M. mixtura by the combination of characters:(1) apart from the stripes, bar-shaped and oval-shaped patterns, the rounded spots present on the dorsum of body and legs;(2) the outer metacarpal tubercles prominently larger than the inner one;(3) of males, the ratios of HW, IND, UEW and LAW to SVL of the new species were significantly larger than those of M. mixtura(P 〈 0.01), and the ratios of SL, IOD, LAHL, HLL, TL, TFL and FL to SVL of the new species were significantly less than those of M. mixtura(P 〈 0.05).展开更多

From 2009 to 2016, a biology study was conducted on population dynamics and embryonic development. Spring season is the peak of the eclosion of overwintering larvae or pupae. The average longevity of adult was 14.8 ± 6.2 days (N = 174), the average number of eggs laid was 259 ± 3 eggs/moth (N = 2), the hatching rate of eggs was 95.4% (N = 262), and the average hatching time of eggs was 99.6 ± 18.6 hours (N = 68). The average body length of males was 5.64 mm ± 0.91 mm (N = 30), and the average body length of females was 6.28 mm ± 0.84 mm (N = 30). This finding indicates that female snout moths are larger than males (Global R = 0.058, P = 0.012). The snout moth eclosion rate was 16.9 moths/100 pods in the first year (2010/2011, N = 2,224 pods) and 10.9 moths/100 pods in the second year (2014/2015, N = 6,382 pods).

文摘A new species of the genus Tylototriton is described,from Yuexi county,Anhui province,in the south of the Dabie Mountains.It is based on morphological and molecular analysis.The new species is identified as belonging to the Tylototriton asperrimus group and shares a number of similarities with T.wenxianensis,T.broadoridgus and T.dabienicus.The diagnostic characteristics of the new species are as follows: the head length is greater than the width of the head; bony ridges on the head are prominent and necked-in; the distal digit ends,ventral digits,peripheral area of the cloaca and the tail's lower edge are orange.The result from the molecular analysis of the genus Tylototriton(including the type specimen of the new species) based on three mitochondrial genes(ND1,ND2 and CYTB) indicated that the new species was close to T.wenxianensis,T.dabienicus,and T.broadoridgus,but formed an independent clade.This result was consistent with the morphological analysis above,which supports the theory that the population distributed in the south of the Dabie Mountains,namely in from Yuexi county,Anhui province,represented a distinct species,Tylototriton anhuiensis sp.nov.

文摘We described a new species, Microhyla beilunensis sp. nov., from Zhejiang Province of China. Phylogenetic analyses based on the mitochondrial 12 S, 16 S and CO1 gene sequences suggested that the new taxon was distinctly separated from its congeners and closed to M. mixtura and M. okinavensis. Morphologically, the new species could be identified from its congeners except M. mixtura by several characters:(1) rudimentary webs on toe base;(2) absence of disks and dorsal median longitudinal grooves on finger tips;(3) presence of disks and dorsal median longitudinal grooves on toe tips. As well, the new species could be identified from topotype M. mixtura by the combination of characters:(1) apart from the stripes, bar-shaped and oval-shaped patterns, the rounded spots present on the dorsum of body and legs;(2) the outer metacarpal tubercles prominently larger than the inner one;(3) of males, the ratios of HW, IND, UEW and LAW to SVL of the new species were significantly larger than those of M. mixtura(P 〈 0.01), and the ratios of SL, IOD, LAHL, HLL, TL, TFL and FL to SVL of the new species were significantly less than those of M. mixtura(P 〈 0.05).
