Need more infos and high quality images to answer this question.

Dear Aamir,

I think, your pictures and also your attached informations are, compared with other questions on RG, very good.

Professor Fürsch, a friend of mine and a profound specialist of Cocinellidae, told me, your specimen is of the genus of Chilocorus.

Best wishes

Rudolf

Sorry- I did not see the pictures...

Thank you, dear Rudolf, for the help. In our region the reported, related chilocorus species are C. nigrita, C. subindicus, C. melas and C. rubidus. The present species differs from them all in having completly black head and metallic bluish black elytral colour.

C. nigrita

Length 3.2-4.0 mm; width 2.9-3.9 mm. Form subrounded, almost hemispherical and strongly convex. Head dull orange yellow. Pronotum dark pitchy brown to black in middle, paler on sides, anterolateral flaps orange yellow. Elytra black, shiny, with fine punctations. Ventral side including legs and inner margins of elytral epipleura orange yellow to yellowish brown, outer margins of epipleura pitchy brown to black.

Chilocorus subindicus

Almost same as C. nigrita

Chilocorus melas Weise

Length 3.1-3.8 mm, width 2.9-3.7. Form round, hemispherical and strongly convex. Head dark brown to blackish (with an anterior yellowish brown area in females), pronotum almost wholly blackish to dark brownish or piceous (only anterior margin lighter brown), parts of ventral side also blackish or piceous; punctations on sides of elytra generally coarser and more strongly impressed than those on disk.

Chilocorus rubidus

Length 5.8-7.2 mm, width 4.5-6.0 mm. Form  medium to large, short oval, narrowed in posterior half, strongly convex. Head, pronotum and scutellum black. Elytra dark burgundy or beet red, with indistinctly defined blackish lateral margins. Ventral side dark reddish brown, except head, pro- and metasterna, elytral epipleura and legs black.

Hello Aamir,

did you include the possibility, that this specimen is not native? Chilocorus species are used in biological pest control and so shipped around the world.

Prof. Fürsch cannot determine your specimen to species level, he is almoust 90 years old and had spent his collection and all his literature to a museum (ZSM), I'm sorry.

Rudolf

The quality of the photographs is not good enough. Genital organs are not visible. Any identification made on base of the photographs is just a kind of speculation.

Dear Rudolf, you're right and it probably seems to be a non-native species (or genus), but thanks for the help.

Dear Lateef, I'm well aware of the 13 species of chilocorus reported from India and the 4 species that I have mentioned previously are the only ones that are closely related to the present species. And as far as Miss Poorani's collection is concerned, it's the largest collection from India and she is the only renowned coccinellid beetle expert from our region. But unfortunately, she has no such specimen matching the current species (confirmed by her). Nevertheless, she has asked for some specimens for the probable identification, which I have already dispatched to her institute. Anyway, thanks.

Dear Aamir,

I wonder if you have already answer from Dr. Poorani? (As I value her knowledge about ladybirds in the worldtop.)

You can always give it a try yourself with this article:

As I think you are close with the genus Orcus.

Please let us know when you have the answer. (And thanks for the good foto.)

Kind regards, Johan

Dear Johan,

Thank you for your inputs. As regards this species, it was identified by Dr. Poorani as Simmondsius pakistanensis (Ahmad & Ghani, 1966).
