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.

Update (11/4/2017): from Facebook, it looks like folks are finding them. Here’s an image.
Update (9/13/2017): the Nanai have begun to emerge! This cicada last emerged in 2009 in Nadroga-Navosa and Serua Provinces, and now again emerge in 2017. People in Fuji will be able to report sightings to nanai-tracker.herokuapp.com.
Notes from Chris Simon:
Early this morning I got the first Reports of the 8-year periodical Nanai emerging in Navosa, Fiji! Some people in that area had them for dinner.
This confirms earlier reports of the eight year periodicity. There was some uncertainty because the original specimens were dated (1906) a year later than they would be if on the current 8-year schedule.
Duffels and Ewart (1988, The Cicadas of the Fiji, Samoa, and Tonga Islands, their taxonomy and Biogeograohy) noted that, “Until recently the present species is only known from three males collected in “Fijii” in 1906 by C. knowles.” Duffels was not able to describe them when he first saw the specimens because they were missing the male genitalia. After obtaining, “a series of females and two males” from Dick Watling and Andrew Laurie in 1986, Duffels was able to assign it to the genus Raiateana. There is one other species of Raiateana in Fiji, R. kuruduadua (two subspecies in Fiji and one in Samoa) but it is not periodical as far as we know.
You might be familiar with American periodical cicadas (Magicicada) and the World-cup synchronized Chremistica ribhoi of India, but Fiji has a periodical cicada too: the 8-year periodical Nanai cicada aka Raiateana knowlesi.

Title: A revision of the Myopsalta crucifera (Ashton) species group (Hemiptera: Cicadidae: Cicadettini) with 14 new species from mainland Australia
Author: LINDSAY W. POPPLE
The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.
Periodical cicadas (Magicicada septendecim, people call them “locusts”) will emerge in the Finger Lakes area of New York state in 2018.
This group of cicadas is called Brood VII (7), and is known as the the Onondaga Brood.
Here’s an old map of the brood from entomologist C. L. Marlatt:
A more up to date map and more comprehensive information can be found on Magicicada.org.
A pair of Magicicada septendecim:
What: Brood VII is the smallest periodical cicada brood in the U.S., and is isolated in the Finger Lakes area of New York State. Only one species of cicada belongs to the brood: Magicicada septendecim (click link for sounds, video). This cicada has a 17-year life cycle. Sadly, Brood VII will likely be the next Brood to go extinct.
Where: the Finger Lakes area of NY State. The following counties have had these cicadas in the past: Cayuga, Livingston, Monroe, Onondaga, Ontario, Seneca, Steuben, Wyoming, York.
There’s a strong possibility that Brood XXIIstragglers will also emerge in parts of Louisiana, Mississippi, southern Ohio & northern Kentucky. So, if you come across periodical cicadas in those areas, they’re Brood XXII, not VII.
