Pachypsaltria cinctomaculata (Stål, 1854)

Pachypsaltria cinctomaculata (Stål, 1854) is found in Columbia, Bolivia, Ecuador, and Venuezela.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Cicadatrini
Genera: Pachypsaltria
Species: Pachypsaltria cinctomaculata (Stål, 1854)

Pachypsaltria cinctomaculata (Stål, 1854)

Pachypsaltria genus description by W. L. Distant:

Characters. — Head including eyes a little more than half the width of base of mesonotum, the front subconically produced, about as long as vertex, head obliquely depressed, eyes oblique, slightly passing the anterior pronotal angles; face moderately globose, not longitudinally sulcate; rostrum passing the posterior coxas; pronotum shorter than mesonotum, its posterior margin nearly twice as broad as anterior margin, the lateral margins dentately sinuate; mesonotum shorter than head and pronotum together, convex; abdomen short, about as long as head and pronotum together; tympanal orifices inwardly exposed; opercula short, broad, scarcely extending beyond base of abdomen: body pilose, marginally longly so; anterior femora not spined beneath; tegmina more than twice longer than broad, apical areas eight; wings with six apical areas.

Pachy (Greek) means thick, and psalt comes from “psalter” (Greek), which means harp player. Pachypsaltria = thick harp player.

Hemisciera maculipennis (de Laporte, 1832)

I’m starting a new series on this blog called “has its name changed?” I’m looking through old documents and papers and using modern documents like Allen Sanborn’s Catalogue of the Cicadoidea (Hemiptera: Auchenorrhyncha) to check. Cicada names change from time to time, based on new discoveries by the modern cicada research/science community, and sometimes to fix grammar (like gender agreement between genus and species).

This cicada is Hemisciera maculipennis (de Laporte, 1832), also known as the “stop and go” or “stop light” cicada because of the red and green color of its wings. If you want to see one in real life, they exist in Central and South America, specifically Panama, Ecuador, Brazil, and adjacent nations. If you’re in New York and you want to see one, they have a few in the collection at the Staten Island Museum — last time I was there, there was a faded one in a display by the door (UV rays fade cicada specimen colors).

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Piccinini
Sub Tribe: Guyana
Genera: Hemisciera
Species: Hemisciera maculipennis (de Laporte, 1832)

And, since 1914 at least, its name has not changed.

Hemisciera Amyot & Serville genus description by W. L. Distant:

Characters. — Head (including eyes) considerably broader than base of mesonotum, eves porrect, more or less stylate, length of head about equal to half its breadth between eyes, and distinctly shorter than pronotum which is about equal in length to mesonotum; abdomen a little shorter than space between apex of head and base of cruciform elevation, tympanal coverings in male with their inner margins strongly concave; metasternal plate well developed, centrally longitudinally impressed and anteriorly produced on each side; rostrum reaching the posterior coxae; anterior femora strongly spined beneath; opercula in male small, transverse, not extending beyond base of abdomen, tegmina about two and a half times as long as broad, with eight apical areas and the basal cell about as long as broad.

Links for further research:

If you’re researching Cicadas in the Neotropic ecozone, which is Central and South America, here are some resources that will help you:

1) Follow Andreas Kay’s Flickr feed. He posts many excellent cicada photos from Ecuador. Many cicadas found in Ecuador are not endemic, so the cicadas you see in Andreas’ Flickr feed should be found in adjacent countries.

2) Visit Cigarras do Brasil – Brazilian Cicadas for photos and information about the cicadas of Brazil.

3) Read Jacobi (1907) “Homoptera Andina”. (Not sure where to find it – maybe eBay).

4) Read: Insecta. Rhynchota. Hemiptera-Homoptera. Volume I (1881-1905) by W. L. Distant and W. W. Fowler. It is available online. Here is a sample from that book:

Insecta. Rhynchota. Hemiptera-Homoptera. Volume I (1881-1905) by W. L. Distant and W. W. Fowler

5) Search for papers written by Allen F. Sanborn. Here is how to search for cicada research papers online.

6) Use ITIS to traverse cicada species names and get listings of papers about the cicada — then search for the cicada names and papers.

5) Many photos and sound files of Paraguayan cicadas.

Thanks again to David Emery!

Zammara with a collar like Dracula!

Just in time for Halloween… the Zammara a genus of cicadas with a collar like Dracula!

Andreas Kay has been posting photos of the insects of Ecuador on Flickr for around a year now. He’s posted many excellent cicada photos, particularly, photos of Zammara. They are among the most visually interesting cicadas.

Cicada, Zammara tympanum?
