Another Stratiomyidae, that I belive to be a Raphiocera sp., and would be great if someone could confirm its ID, as also, identify the fly of my thread "Brazilian Stratiomyidae #1", that until now was not replied. Photo #1  Coordinates of the place where I took this photo: Latitude: -22.538442719452, Longitude: -43.228293657303 Date and time: December 1, 2011 at 9.41.04am GMT+3 Photo #2  Coordinates of the place where I took this photo: Latitude: -22.538442719452, Longitude: -43.228293657303 Date and time: December 1, 2011 at 9.41.44am GMT+3 Thanks for help!

This beautiful fly is Heptozus sp. It is on the cover of this book: http://www.amazon.com/Manual-Central-American-Diptera-v/dp/0660198339 . |

The antennae are different. Are they highly variable within Heptozus? See thread 45072. http://www.dipter...d_id=45072 |

Ah, I didn't see that thread...thanks John. I need to follow ChrisR's advice and leave the strats alone! I notice the coloration of the thorax is a bit different too. Since Steve Marshall's photo is ID'd as Heptozus sp., I assume there is some variation among the two presently known species of this genus (MCAD: 543). But this same source does mention Lysozus as a better alternative antenna-wise. |

I found an article with nice pictures of this fly, where Diego Aguilar Fachin, from USP - Ribeirão Preto (SP) and João Paulo Morselli, from Department of Zoology, Insect Sistematic Laboratory, UNESP/Botucatu (SP), identified this fly as Raphiocera sp.. You can check the article here: http://www.ra-bug...php?id=967 And the gallery with pictures here: http://www.ra-bug...php?id=967 I would like to know what all of you have to say about this ID. Thanks you all. AC |

I can see several minor differences in the fly in the article (different pale markings, C extended past tip of R5, indentation in dark patch at tip of R1 is triangular). I assume these make it a closely related species, but they could be sexual dimorphism, intraspecific variation, or even generic characters. |

I'm inclined to consider this fly (as well as a similar Brazilian one elsewhere in the Forum) Raphiocera armata (Wiedemann). Fits imho the description in James, 1943 (Ann.Ent.Soc.Am. XXXVI: 376 as Basentidema coerulescens, sp.n.; synonymy in Pimentel&Pujol-Luz, 2001). Scape is not elongate so not a Heptozus (extralimital as well). As far as I know Lysozus Enderlein, 1914 mentioned here is a rather enigmatic genus.
