Hishimonus Ishihara
No full textHishimonus Ishihara Hishimonus Ishihara 1953: 10. Type species: Thamnotettix sellata Uhler, by original designation. Description. (Modified from Knight 1970 a and Dai et al. 2013) Small leafhoppers, 3.0–4.0 mm long, yellow in colour, sometimes marked with brown, legs and venter stramineous, forewings silvery white with dark brown mottling and large brown semicircular spot against midlength of commissural margin forming, when wings at rest, conspicuous circular or diamond shaped spot with that of opposite wing (henceforth called median spot). Head as broad as pronotum or broader, slightly longer medially than next to eye with anterior margin broadly rounded; narrowly rounded to face; frontoclypeus longer than wide; clypeal sulcus distinct; clypellus elongate with sides parallel over basal 0.66, slightly expanded at apex; genal margins concave beneath eyes; ocelli on anterior margin, contiguous with eyes or separated by a distance less than own diameter; a shallow transverse furrow on vertex between ocelli; vertex posterior to furrow glabrous, face and vertex anterior to furrow shagreened. Pronotum approximately twice length of vertex, sides short, posterior margin transverse or shallowly concave; surface glabrous, transversely and feebly striate. Scutum and scutellum together shorter than pronotum. Forewings with claval veins joined by cross vein at midlength; inner subapical cell open basally, outer subapical cell elongate with ends transverse; appendix small. Fore femur with setal arrangement as follows: 2 AD at apex, well developed AM1, 9– 13 IC, 6–8 PV and 12–13 short AV. Fore tibia with 1 + 4 (AD+PD) setae. Hind femoral apical setal formula 2 + 2 + 1. Male pygofer acutely rounded posteriorly, with stout setae over posterior half, without processes; dorsal surface approximately 0.33 of total length. Subgenital plate tapering posteriorly to membranous fingerlike process (except H. indicus and H. viraktamathi), uniseriate row of stout setae laterally, becoming multiseriate basally, with a more lateral row of long filamentous setae over apical half. Connective Y-shaped with stem long or short. Styles terminating in posteriorly directed fingerlike process, subapical lobe present. Aedeagus with two dorsally directed shafts each with gonopore near apex, with or without basal processes. Female with gonocoxa I usually broader than width of first pair of valvulae at base. Sculpturing of first pair of valvulae imbricate and reaching dorsal margin. Teeth on second pair of valvulae in apical 0.33 length, without dorsal median tooth. Remarks. Hishimonus differs from Hishimonoides, Litura and Naevus Knight with which it is closely related in possessing neither preatrial processes of the aedeagus (sometimes referred to as paraphyses) nor with a ventrally extended preatriumwithout process. Some species of Hishimonus, such as H. indicus (Sohi) and H. viraktamathi Knight, have basal processes to the aedeagus, which resemble the preatrial process of Litura and their assignment to this genus is only provisional. The following key will separate the four genera under discussion.Published as part of Viraktamath, C. A. & Anantha Murthy, H.

`Kronecker's density theorem and irrational numbers in constructive reverse mathematics'
No full textTo prove Kronecker’s density theorem in Bishop-style constructive analysis one needs to define an irrational number as a real number that is bounded away from each rational number. In fact, once one understands “irrational” merely as “not rational”, then the theorem becomes equivalent to Markov’s principle. To see this we undertake a systematic classification, in the vein of constructive reverse mathematics, of logical combinations of “rational” and “irrational” as predicates of real numbers
On the contrapositive of countable choice
Get PDFWe show that in elementary analysis (EL) the contrapositive of countable choice (CCC) is equivalent to double negation elimination for Σ^0_2-formulas. By also proving a recursive adaptation of this equivalence in Heyting arithmetic (HA), we give an instance of the conservativity of EL over HA with respect to recursive functions and predicates. As a complement, we prove in HA enriched with the (extended) Church thesis that every decidable predicate is recursive

The weak König lemma, Brouwer's fan theorem, de Morgan's law, and dependent choice
No full textThe standard omniscience principles are interpreted in a systematic waywithin the context of binary trees. With this dictionary at hand we revisit the weakKönig lemma (WKL) and Brouwer's fan theorem (FAN). We first study how one canarrive from FAN at WKL, and then give a direct decomposition, without coding, ofWKL into the lesser limited principle of omniscience and an instance of the principleof dependent choices. As a complement we provide, among other equivalents of thestandard omniscience principles, a uniform method to formulate most of them

Lu Lin; 1 male, Yingjiang County, Zhanxi Town, 1009m, 02.VI. 2011, coll. Lu Lin, at light. Remarks. An adequate description of this species was given by Ghauri (1971). But some variation occurs as follows. Crown and forewing with or without black markings (Plate II: A–F). Pygofer side usually distodorsal corner round, distoventral corner pointed, spine 1 long, spine 2 and others absent (Fig. 8 B), but much variation is found (Figs. 6–9); style usually as in Fig. 10 C, apophysis of style is always shorter, but its shape varies (Figs. 10– 11); aedeagal shaft usually as in Figs. 12 B, 13 B, but much variation is found (Figs. 12 A–F, 13 A–I), the paired median lateral processes of aedeagal shaft short (Figs. 12 A–F, 13 A–I), but the relative length of the shaft and the shape of median lateral process varies, and the number of aedeagal spines also varies usually from 3–5 (Figs. 12 A– F, 13 A–I). The nearly round crown of both males and females make this species very distinct (Plate II: A–F). PLATE II. Nephotettix malayanus Ishihara & Kawase.
