Siamiassus constanti Dai, Dietrich & Zhang, 2015, sp. nov.
No full textSiamiassus constanti sp. nov. (Figs 5 C, D, 20 A–D, 23 A) Male 8.4 mm long, 3.9 mm wide across humeral angles. Color dull olive green; forewing densely marked with small black spots in basal 2 / 3 and along veins near apex; front and middle femur black in distal half, front tibia dark brown (Fig. 5 C, D). Structural features as described for genus (Fig. 20 A–D). Type material. Holotype ♂ THAILAND: Loei, Na-Haeo (edge pond) 17.v. 2003, J. Constant & K. Smets, light trap [RISB]. Notes. This species is named in honor of Dr. Jerome Constant, Auchenorrhyncha expert at the Royal Belgian Institute of Natural Sciences, Brussels, collector of the holotype and host to CHD during a recent visit to Brussels. Siniassus nom. nov. (replacement for Sinojassus Dai, Zhang, Zhang & Dietrich 2010, nec Sinojassus Zhang 1985) Notes. The genus was described by Dai et al. (2010) and given the name Sinojassus, but this name is a junior homonym of an older fossil genus, Sinojassus Zhang (1985) and, therefore, must be given a new replacement name. Siniassus resembles Trocnadella in overall body form and the absence of a separately articulated connective in the male genitalia, but may be distinguished by the presence of numerous dark spots on the dorsum and the elongate style apodeme.

No full text8. Hendecaneura triangulum Zhang & Li, 2005 Hendecaneura triangulum Zhang & Li, 2005, Oriental Insects, 39: 114. TL: China, Guangdong Province, Xinyi; TD: NKUM. Forewing length 8.0 mm. Specimen examined. 1♂, CHINA: Guangdong Province, Xinyi, alt. 1,000 m, 8 August 2003, coll. D. Zhang, genitalia slide no. ZAH04109. Distribution. China (Guangdong). Remarks. The male forewing has a circular pocket at base of 1A+2A vein in H. triangulum. This species resembles H. axiotima (Meyrick) in the male genitalia, but differs by forewing with a white triangular patch above ocelloid patch, tegumen blunt dorsolaterally and uncus triangular. In H. axiotima forewing bears a wide creamwhite streak not touching costal triangular patch apically, tegumen bears a pair of large ear-like lobes and uncus is mound-like.Published as part of Zhang, Aihuan, 2021, Study on the Genus Hendecaneura Walsingham from China (Lepidoptera: Tortricidae), pp. 359-366 in Zootaxa 4966 (3) on page 365, DOI: 10.11646/zootaxa.4966.3.7, http://zenodo.org/record/473679

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
