DISTRIBUTION:

Citheronula armata sonyae (wingspan: males: 75mm; females: larger) flies in
Argentina, and seems limited to Salta Province, but it
might?? also be in Bolivia: Chuquisaca; and Paraguay.

The populations in Bolivia and Paraguay seem somewhat in question, with the Paraguayan specimens from Sapucay, Paraguari, Paraguay, represented by the holotype of nominate armata. Many of the other specimens from Bolivia and other areas in Paraguay seem intermediate between subspecies sonyae and the nominate subspecies, armata.

Ryan Saint Laurent had previously sent me images from Parana, Brazil, that seem a best match for the recently (2014) described Citheronula maranhensis from Maranhao, but they are so far removed geographically, that they might represent an undescribed species or subspecies. The colouration and patterning are very good matches for maranhensis.

This subspecies is larger than the nominate subspecies and is characterized by "narrower and less contrasting dull orange veins."

Ryan Saint Laurent observes, "According to Lemaire, "sonyae" has slate grey fringes while the nominate [species] has uniformly orange fringes. I also note that nearly all the greyer individuals of armata (including the ones on WLSS) have a discal spot on the hindwing fused with the red/orange of the base of the HW.

"In yellow fringed nominate armata the discal spot is nearly always separate from the base. Compare the pair I've sent with the male and pair on WLSS (I'll admit that the red spot of the HW is less so connected to the base than in other sonyae-like individuals) but the overall greyness of the two on WLSS is very clearly different from the individuals I have sent. I also sent a larger image of the female.

"Overall, it seems as though sonyae may not be a subspecies, but rather a form of armata, at least in my opinion. Also, the "sonyae" male in Lemaire has the fused discal spot as well, while the nominate has a free spot."

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths are on the wing in March. Citheronula armata sonyae larval hosts are unknown, but they may feed e feed on Cashew nut (Anacardium occidentale) and Jatropha.

ECLOSION, SCENTING AND MATING:

Female Citheronula armata sonyae moths extend a scent gland from the posterior tip of the abdomen to call in the night flying males which become active around 11:30 pm.

EGGS, LARVAE AND PUPAE:

Mature larvae descend tree trunks to pupate in underground chambers. The following images were sent to me by Kirby Wolfe as Citheronula armata, without a subspecific designation. I now believe they are of Citheronia armata sonyae (originally placed on armata armata file), but note the following regarding the image of the male moth.
A) The forewing fringes are grey as would be expected in sonyae and not armata.
B) The hindwing fringes are yellowish-white with some bleeding of orange as would be expected in armata and not sonyae.
C) Other features such as reduced yellow on forewings, thinner orange wing veins, shape and position of hindwing cell and larger dark post median area of hindwing are all suggestive of sonyae.

I think the moth and larvae are more likely Citheronula armata sonyae and will post same on the sonyae file with these notes. It is also possible there is a third Citheronula species/subspecies that is depicted but not yet officially described. (Bill Oehlke)

If sonyae and armata are found to be sympatric in some areas, then sonyae would have to be elevated to full species status.

Larval Food Plants

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

The source of the genus name "Citheronula" is probably Mount Citheron (Greek mythology), an untamed wilderness, exempt from the laws of civilization. The goddesses go naked there and are free from any of the pressures of society.

The species name "armata" might ?? refer to the 'spiny' appearance of the light areas on the wings or may refer to a structure on the genitalia.

The subspecies name is probably honourific for a woman named Sonya.
