We evaluate species, species group, and generic concepts for Ophiderini and Phyllodini (Lepidoptera: Calpinae) with a cladistic analysis of COI 5 mitochondrial DNA sequences. Species recognized by current taxonomy formed monophyletic clades with three exceptions: Eudocima phalonia (L.), E.

A wide range of metals exhibit anomalous electrical and thermodynamic properties when tuned to a quantum critical point (QCP), although the origins of such strange metals have posed a long-standing mystery. The frequent association of strange metals with unconventional superconductivity and antiferromagnetic QCPs has led to the belief that they are highly entangled quantum states. By contrast, ferromagnets are regarded as an unlikely setting for strange metals, because they are weakly entangled and their QCPs are often interrupted by competing phases or first-order phase transitions.

Catocala becheri Borth, Kons & Saldaitis, 2017 was recently described from Central Vietnam. It is a member of a morphologically well-defined group including Catocala intacta Leech, 1889 and Catocala hoferi Ishizuka & Ohshima, 2003 which both differ from C. becheri in wing pattern and male genitalia.

The Asian Catocala naganoi species group is delimited and reviewed, with a diagnosis of the constituent species based on genitalic, wing pattern, and COI 5' mtDNA characters. The included species are Catocala naganoi Sugi, 1982, C. solntsevi Sviridov, 1997, C.

The taxonomy of the Catocala nupta (L.), 1757 complex is analyzed using corresponding characters of the male genitalia, wing pattern, and COI 5' mitochondrial DNA, and is presently found to contain only two additional species: Catocala concubia Walker, [1858], and a new species Catocala benedeki described herein. Three new lectotypes are designated, and 12 status changes for existing names are introduced (10 new synonyms, 2 revised statuses).

Here we describe Catocala didenko sp. n. as new for the noctuid genus Catocala Shrank, differing from Catocala duplicata Butler, 1885 and Catocala gansan Ishizuka & Wang, 2013 on wing pattern, male genitalia, and COI 5' mitochondrial DNA.

Unconventional superconductivity and other previously unknown phases of matter exist in the vicinity of a quantum critical point (QCP): a continuous phase change of matter at absolute zero. Intensive theoretical and experimental investigations on itinerant systems have shown that metallic ferromagnets tend to develop via either a first-order phase transition or through the formation of intermediate superconducting or inhomogeneous magnetic phases. Here, through precision low-temperature measurements, we show that the Grüneisen ratio of the heavy fermion metallic ferromagnet YbNi(4)(P(0.

The faunistic composition of the family Cossidae (Lepidoptera) of the Socotra Archipelago is revised. Five species are recognized, including two new species (Mormogystia brandstetteri and Meharia hackeri), and dubious identifications and records are discussed. Adults and genitalia are illustrated and bionomic details, DNA barcodes and a synonymic checklist for Socotran cossids are provided.
