Just an African planthopper tint... (a really weird one)

Most Dichopterinae don't have a cephalic process.
There are no Dichopterinae found in Africa.
And their cephalic processes can't tilt to drink sap.

With the exception of Dorysarthrus alfierii(yes, it's from @psyllidhipster's guide, just I added extra pointers)

And it has an unusual colour for it's subfamily: ochraceous. Most provably, the reason that it helps in camouflage, as it's found in northern Africa, which is mostly a desert.

FAQ on Parancyra, Ancyra and similar sp.

People hove seen these genra may ask 2 questions : "why do they need to look like walking backwards?" and "what are those antennae in the back"? Here are the answers:

#1 - Why do they need to look like walking backwards

Well, it's actually to scare predators as they may look "seriously alien", and may put predators at bay. It actually makes the predators think that it is their predator (Note the large size, Ancyra seems to be bigger). the eye pattern/spot on each wing mimic eyes, and the wings work as antennae, and all of that effect is created by the wings, so when it was forwards, it looks like moving backwards;

#2 - What are those antennae placed on the back

At the apex of the wings, the wings are elongated into a stick like projection that ends with a club, that mic antennae. On top of that, planthopper antennae are small, so they can't easily seen. the antennae of most true hoppers (auchennorhyncha) are of 3 segments: a cone, on top it is a sphere, and finally a short small thread or needle shaped projection (not sharp at all, it's completely safe to touch them), and the total length of a planthopper antenna is generally smaller than 1cm!

Pyrilla of India 101: How to differentiate each species

Pyrilla is an interesting genus of dull, mostly brownish yellow, planthoppers of the family lophopidae. This journal shares everything I know about Indian pyrilla, with a key to the species.

I have been lucky enough to see all species listed here! (Yes, all indian pyrilla species are on my profile, except one mysterious one which I could not take a photo of because it hopped away, I have included it.)

Because of that "mysterious one"'s find, I prefer to divide pyrilla into two groups: p. perpusilla group and p. sp. group

Note:

While I have given length for each species, I don't know if that is correct, as it's only from the specimens which I found, which may be of any age so that is not accurate; Also all species' descriptions except p. sp, which I saw last year, are, based on dead specimens, so descriptions can be inaccurate;

The key

1 ..... A typical, translucent, brownish yellow winged, pyrilla ..... P. perpusilla group
|_ 1.1 ..... Carinae below eyes ..... P. abberans
|_ 1.2 .....No carinae below eyes ..... P. perpusilla "subgroup" (yes, I do consider it like this)
|_ 1.2.1 .... A mostly peach snout, and a peaches mustard thorax with brown eyes ..... P. lycoides
|_ 1.2.2 ..... A brown species, yellow in dead/faded specimens ..... P. perpusilla
2 ..... Hyaline wings (You will understand why I include this in the description I give) ..... P. sp group
|_ 2.1 ..... Snout black above, olivaceous below; the rest of the face is black with chocolate brown (A very dark shade of brown) ..... P. sp

Description of species

Pyrilla abberans



P. abberans:
Picture 1: Epipyropidae (planthopper parasite moth larvae) on abdomen and hyaline hindwings;
Picture 2: Head and carinae;

A species with carinae under the eyes, a typically greyish snout, and one of the most unique species to me after protuberans and sp.; a quite common species, they come flying to my tubelight in monsoon when I keep the windows open.

Length: HT 2cm; Distribution within India: Uttar Pradesh(west, Especially Noida) and nearby(I'm in Noida, Uttar Pradesh!)

Pyrilla lycoides


P. lycoides (sorry, the image is blurry but it did have spots)

A slightly bigger species without carinae under the eyes, a typically peachish snout, and one of the most rare species with the exception of P. sp.; they also come flying to my tubelight in monsoon.

Length: HT 2.1cm; Distribution within India: Uttar Pradesh and nearby(all observations as of now are from Uttar Pradesh).

Pyrilla perpusilla


Pyrilla perpusilla

The type species, it also doesn't sport carinae under the eyes, a typically brownish snout, and one of the most rare species with the exception of P. protuberans and P. sp.; they also come flying to my tubelight in monsoon.

Length: HT 1.9cm; Distribution within India: Ranges from Uttar Pradesh to West Bengal.

Pyrilla sp.

The "mysterious" species, it too doesn't sport carinae under the eyes; I'm giving a longer description here:

Wings, including membrane, almost hyaline, and dotted with black or extremely dark brown; The eyes very dark brown; the head was black, the snout was olivaceous below, and black above, the snout was shaped like pyrilla species' snouts, and the wing's dotted pattern was also similar to pyrilla, so I include it in the genus;
provably this will be transferred to another genus in the future, and would be the closest relative of actual pyrilla, but it is supposed to be within pyrilla.

Length: HT 2.1cm; Distribution within India: Noida, Uttar Pradesh

I hope this will be useful to you
