Some Properties of Hall–Yamada Semigroups
No full textAbstractThe Hall–Yamada structure theorem for orthodox semigroups utilizes the orthodox semigroupH(B,T,ψ) which is built up from a bandB, an inverse semigroupT, and a morphism ψ fromTintoWB/γ, whereWBis the Hall semigroup ofBand γ is its least inverse semigroup congruence. In this paper we cosmetically alterH(B,T,ψ) and then proceed to characterize properties of this altered semigroup in terms of properties of (B,T,ψ)

This new species is most similar in general appearance to L. zhangi, from which it can be distinguished by the larger body size [3.5–3.9 mm in L. zhangi], parameres strongly acute at apex [blunt at apex], and acus straight [curved]. Also, whereas L. ichikawai resembles L. variegatus in the shape of the male genitalia, the following external characters of the former are significantly different from the latter: posterior margin of pronotum narrowly pale yellow [broadly pale yellow in L. variegatus]; clavus blackish brown, with pale yellow markings on basal and median part [almost pale yellow excluding darkened area along claval suture and inner margin]; embolium blackish brown, with pale yellow markings on basal part [mostly pale yellow, with dark brown on median part]; and apex of left paramere not bent inwardly [rather slender and slightly bent inwardly].Published as part of Yamada, Kazutaka, Yasunaga, Tomohide & Ichikawa, Toshihide, 2012, A new species of Lyctocoridae (Hemiptera: Heteroptera: Cimicoidea) feeding on the exuded sap of Sawtooth Oak, Quercus acutissima, in Japan, pp. 65-74 in Zootaxa 3525 on pages 67-71, DOI: 10.5281/zenodo.28272
