No full text5. Adelencyrtus brachycaudae Xu & Shi (Figs 20−25) Adelencyrtus brachycaudae Xu and Shi, 1999: 202, 206. Holotype Ψ (HNAU, examined), China. Adelencyrtus brachycaudae; Zhang & Huang, 2004: 22; Xu & Huang, 2004: 35. Description. Female. Body length 1.1−1.4 mm. Body dark brown with green or blue sheen; antenna (Fig. 20) generally dark or dark brown with F 6 yellowish and sometimes F 5 ventrally yellowish; fore wing (Fig. 21) distinctly infuscate, with two hyaline spots beyond stigmal vein; fore leg dark brown except apices of femur and tibia marked with yellow; mid leg yellow except coxae entirely, femur subapically, and tibia subbasally marked with dark brown (Fig. 23); hind leg yellow except coxa entirely, femur largely, median 1 / 3 of tibia, and apical tarsomere dark brown (Fig. 24). Head. Frontovertex about 1 / 4 head width; ocelli arranged in an angle of about 45 º; posterior ocelli touching inner eye margin, and separated from occipital margin by about 3 × its own diameter; antennal scape about 4 × as long as broad; F 1 −F 4 transverse and subequal in size, F 5 and F 6 subquadrate; clava about as long as funicle; mandible quadridentate. Thorax. Fore wing about 2.5 × as long as broad; marginal vein about 3 × as long as broad; stigmal vein about 2 / 3 as long as marginal vein; postmarginal vein about as long as stigmal vein (Fig. 21). Gaster. Ovipositor sheaths (Fig. 25) slightly exserted, by about 1 / 7 gaster length. Relative measurements. MT 48, OL 66, GL 16. Male. Similar to female except for antennae and genitalia; antenna with scape yellowish, the rest dark yellowish-brown; wings hyaline (Xu & Shi 1999). Host. Unidentified diaspidid on Pittosporum tobira (Thunb.) (Xu & Shi 1999). Distribution. China (Hainan, Hunan, Yunnan). Type material examined. CHINA: Hunan, Changsha, 14.v. 1989, ex. Diaspididae, coll. G. Xu (holotype Ψ, allotype ɗ, and 5 ΨΨ paratypes, HNAU). Non-type material examined. CHINA: Hainan, Danzhou, Nada, 18.iv. 2005 (1 Ψ), 16.v. 2007 (1 Ψ), coll. Y.Z. Zhang; Diaoluo Mt., 6.v. 2007, coll. Y.Z. Zhang (1 Ψ). Yunnan, Xishuangbanna, 13.xi. 2002, coll. W.Q. Zhen (1 Ψ); Xishuangbanna, 6.viii. 2007, coll. G. Zheng (5 ΨΨ). Comments. Adelencyrtus brachycaudae is very similar to A. inglisiae Compere & Annecke from South Africa in general coloration. The latter species is also very close to A. depressus (Risbec) from Madagascar (Noyes & Prinsloo 1998). Additional study is needed to determine whether these three names represent distinct species or are synonyms.Published as part of Zhang, Yan-Zhou & Shi, Zhen-Ya, 2010, The species of Adelencyrtus Ashmead and Epitetracnemus Girault (Hymenoptera: Encyrtidae) from China, pp. 1-26 in Zootaxa 2605 on pages 8-9, DOI: 10.5281/zenodo.19766
Reflection ordering on the group G(m,m,n)
No full textAbstractIn the paper Shi (2008) [13], we introduced a partial ordering, called the reflection ordering, on the elements of G(m,p,n) and described such an ordering on the groups G(m,1,n), m⩾1. In the present paper, we describe the reflection ordering on the group G(m,m,n). As a by-product, we obtain a formula for the enumeration of a certain subset in the symmetric group Sn, which is of independent combinatorial interest

The algorithms are written in a Pascal-like language extended with high level pyramidal control structures. -from Author
Reflection ordering on the group G(m,p,n)
No full textAbstractIn our previous paper [J.Y. Shi, Formula for the reflection length of elements in the group G(m,p,n), J. Algebra 316 (1) (2007) 284–296], we get a closed formula for the reflection length functions on the reflection group G(m,p,n) with p∈[n] and p|m. In the present paper, we introduce a partial ordering, called reflection ordering, on the elements of G(m,p,n). By applying this formula, we give an explicit description for the reflection ordering on the groups Sn and G(m,1,n), m>1
