Megalestes heros Needham 1930
No full textMegalestes heros Needham, 1930 (Fig. 3e; 4e; 5c, p; 6g) Megalestes heros Needham, 1930: 229–230 [Fujian, Sichuan]; Asahina 1985b: 11, 13, figs. 32–33 [Guadun, Fujian]. Megalestes suensoni Asahina, 1956: 213–216, figs. 12–14 [Tien-Mu-Shan, Chekiang]; Chao 1965, proposed a junior synonym. This is a large, endemic Chinese species mainly occurring in Fujian and Zhejiang. Needham (1930) did not provide any figures for this species. Asahina (1956) described M. suensoni on base of a female specimen from Tianmushan, Zhejiang. After carefully studying another female specimen collected from the type locality of M. suensoni Chao (1965) believed it was a junior synonym of M. heros, which was finally accepted by Asahina (1985b). Chao (1965) also doubted one of the type specimen of M. heros (the teneral male from Sichuan) was true of this species. We have explored Sichuan for many years and have never found M. heros, but the similar-sized species M. omeiensis is present. We agree with Chao (1965) to believe that Needham confused these two species in his original study.Published as part of Yu, Xin & Xue, Junli, 2020, A review of the damselfly genus Megalestes Selys, 1862 (Insecta: Odonata Zygoptera: Synlestidae) using integrative taxonomic methods, pp. 245-270 in Zootaxa 4851 (2) on page 260, DOI: 10.11646/zootaxa.4851.2.2, http://zenodo.org/record/440747

Tikuna bilineata Needham & Murphy, comb. n.
No full textTikuna bilineata (Needham & Murphy) comb. n. Choroterpes bilineata Needham & Murphy 1924: 48; Traver 1947: 156. The genus Tikuna was established by Savage et al. (2005) and Choroterpes atramentum Traver, 1947, was designated as the type species. Following this publication, two species from South and Central America remain incorrectly placed in Choroterpes. The first, Choroterpes bilineata Needham & Murphy, 1924, originally described from female imagos and male subimagos from La Chorrera, Putumayo Dist., Peru (now a part of Colombia), also belongs to the genus Tikuna, requiring the new combination Tikuna bilineata. The holotype and paratypes (Cornell University) were studied by one of us (H.M. Savage); additional specimens deposited at the U. S. National Museum of Natural History, Florida A&M University, and the Zoologische Sammlung des Bayerischen Staates were recorded from Brazil, Ecuador, Surinam, and Venezuela. New records for T. bilineata follow: BRAZIL: 1 female imago, Pará State, Rio Cururu, about 100 km above Mission Cururu, at light, 25 –I– 1962, E.J. Fittkau. ECUADOR: Pastaza Prov., coll. J.

Verifying security protocols by knowledge analysis
No full textThis paper describes a new interactive method to analyse knowledge of participants involved in security protocols and further to verify the correctness of the protocols. The method can detect attacks and flaws involving interleaving sessions besides normal attacks. The implementation of the method in a generic theorem proving environment, namely Isabelle, makes the verification of protocols mechanical and efficient; it can verify a medium-sized security protocol in less than ten seconds. As an example, the paper finds the flaw in the Needham-Schroeder public key authentication protocol and proves the secure properties and guarantees of the protocol with Lowe's fix to show the effectiveness of this method

Megalestes micans Needham 1930

Megalestes chengi Chao, 1947: 15–25, figs. 2, 4, 6, 8, 10–11, 14, 16–17, 21; Chao 1965: 190–191; Asahina 1985b: 9–12. Syn. nov. Megalestes discus Wilson, 2004: 424–427, figs. 4–8, [Mangshan, Hunan, China]; Wilson & Xu 2007: 102–103, “Nanling, Guangdong,” key to species. Syn. nov. Megalestes raychoudhurii Lahiri, 1987: 54–56, figs. 131–132, 298–299, 519 [Meghalaya, India]. Syn. nov. Megalestes irma [nec. Fraser, 1926]: Gyeltshen et al., 2017: 588–594, fig. 4e–f [Bhutan]. This is the most widespread species of Megalestes, occurring throughout South China (Fujian, Guangdong, Guangxi, Guizhou, Henan, Hunan, Jiangxi, Sichuan, Yunnan, and Zhejiang) extending to Vietnam, Bhutan, and India. It is also the only species distributed on both sides of the Himalayas. The diagnostic character for this mid-sized species is the base of the basal tooth on the paraproct bulged, covered in dense setae (Fig. 6 i-j). This species is closely related to M. riccii, and this was confirmed by molecular analysis (Fig. 7). In the description of M. chengi, Chao (1947) only compared his material with M. heros, a totally different species. Later, Chao (1965) stated that the differences between M. chengi and M. micans included the middle portion of the middle lobe of the pronotum green, not yellow (feature 2), and the base of the basal tooth of the paraproct slightly, but not greatly, bulged (feature 15). However, all these characters occur in intraspecies variation (Discussion section). Although both Chao (1965) and Asahina (1985b) have emphasized that M. chengi was very similar to M. micans, neither author confirmed that they are really the same species. We examined eight of the type specimens of M. chengi deposited in IZAS and IEAS including the holotype and found no evident morphological differences with M. micans. The molecular analyses also suggested that these two are the same species (Fig. 7). Therefore, based on both morphological and molecular evidence (Fig. 8), we confirm that M. chengi is a junior synonym of M. micans. As we have previously discussed, diagnostic characters of M. discus cannot separate it from M. micans. Wilson & Xu (2007) mentioned that M. discus have “inferior appendages without a basal pair of stout spines or robust teeth,” which is incorrect, and “occipital margin with/without transverse yellow spot” (feature 1) supports our opinion that this character is not stable. We examined the diagnostic character photos of the paratype of discus (1 m #, Mangshan (near Babaoshan), Shikengkong, S Hunan, China, 26-VI-2000, K.D.P. Wilson leg.), which were kindly sent by K. D. P. Wilson, and found that all the characters are consistent with M. micans. No further information on M. raychoudhurii has been published after its original description. According to the features of caudal appendages and genital ligula in the original description and figures, there is no difference between M. raychoudhurii and M. micans. We believe that both discus and M. raychoudhurii are junior synonyms of M. micans.Published as part of Yu, Xin & Xue, Junli, 2020, A review of the damselfly genus Megalestes Selys, 1862 (Insecta: Odonata Zygoptera: Synlestidae) using integrative taxonomic methods, pp. 245-270 in Zootaxa 4851 (2) on page 262, DOI: 10.11646/zootaxa.4851.2.2, http://zenodo.org/record/440747
