Four new species of Semia cicadas living in Vietnam were described in 2017: Semia magna, Semia spiritus, Semia pallida, and Semia albusequi.
Here’s the details on the paper:

This paper provides descriptions of four new species of the genus Semia Matsumura, 1917 from Vietnam: Semia magna sp. nov., Semia spiritus sp. nov., Semia pallida sp. nov., and Semia albusequi sp. nov. A key to the 13 species of Semia is provided.
Update: a reminder that the World Cup Cicada will be back in 2018 (as will the World Cup)!
Chremistica ribhoi Hajong and Yaakop 2013 is a cicada that lives in the Ri-Boi district of India. C. ribhoi is known as the World Cup cicada because it emerges every four years in synch with the World Cup association football (soccer) tournament.
C. ribhoi is known locally as Niangtasar. It only lives in a very small area: Saiden village (N 25’51’37.1’’; E 091’51’16.3”) and Lailad (N 25’55’09.7” E 091’46’25.0”) situated on the northern part of the state of Meghalaya. The cicada can be identified by the presence of two white spots on either side of the anterior abdominal segment.
Researcher Sudhanya Hajong is gearing up to study these cicadas, since this is the year they will emerge. Ri-Boi area locals use these cicadas as a food source and fish bait. These cicadas are threatened by deforestation (cutting down forests for agricultural purposes). Sudhanya plans to educate locals about conserving them and protecting their habitat.
Most of the facts in the post come from the following document: Hajong, S.R. 2013.

Cicada researcher Robert L. Sanders has written a paper documenting a 3-Year survey of Oklahoma cicadas. The paper is appropriately titled “A 3-Year Survey of Oklahoma Cicadas (Hemiptera: Cicadoidea: Cicadidae) with New State Records” and was published in Journal of the Kansas Entomological Society, 89(4):315-337. Access it via this link.
The number of cicadas identified living in Oklahoma has been raised to 41. The previous number, as documented in the works of Allen F. Sanborn and Polly K. Phillips, was 341.
Here’s the abstract from Robert’s paper:
ABSTRACT: Between September of 2013 and September of 2016 an intermittent survey of the cicada diversity and distribution in Oklahoma was conducted. The results of this survey are presented here as a current updated annotated checklist. Seven species in four genera are newly recorded as resident in Oklahoma: Diceroprocta texana (Davis, 1916), Megatibicen figuratus (Walker, 1858), Neotibicen davisi harnedi (Davis, 1918), Neotibicen linnei (Smith & Grossbeck, 1907), Neotibicen robinsonianus (Davis, 1922), Okanagana viridis Davis, 1918, and Pacarina shoemakeri Sanborn and Heath, 2012. This brings the total number of species inhabiting the state to 41. Discussed are seven additional species possibly occurring in the state and Oklahoma’s cicada diversity.

There’s a new paper from Sarah E. Banker, Elizabeth J. Wade, and Chris Simon titled “The confounding effects of hybridization on phylogenetic estimation in the New Zealand cicada genus Kikihia”.
Here’s the highlights:
- Tested validity of an unexpected “Westlandica” mitochondrial clade with nuclear loci.
- Phylogenetic signal and pattern differ dramatically among nuclear genes but always weak on South Island.
- No conflict between nuclear concatenation vs species trees from multiple methods.
- Three nuclear species trees support major North Island but not South Island mitochondrial clades.

Comments Off on A new paper about Kikihia hybridization
Temperature plays an important part in much of cicada behavior, such as determining when they emerge from the ground, and when they are active above ground.
There’s a new paper out from Allen F.Sanborn, James E.Heath, Maxine S.Heath and Polly K.Phillips titled “Thermal adaptation in North American cicadas”.
Here’s the highlights:
- Thermal responses are related specific environments of North America cicadas.
- Thermoregulatory strategy can influence thermal responses in sympatric species.
- Emergence time can influence thermal responses in sympatric species.
- Subspecies in general do not differ in their thermal responses.
- Thermal responses within a species do not differ in populations separated by more than 7600 km.
