Your unindentifyed Melyrid from New Mexico
I have never seen this genus and it does fit very well with most of your US Dasytinae.
I have been impressed by the head's shape, nearly rostrate and I suggest that it could be a Mecomycter Horn 1882 or a Scuromanius Majer 1995. Both have representatives in the South-West of the USA.
They have been separated from the Melyrid family stock by Majer in 1995 and belong to a small family Mauroniscidae with 5 genera distributed from Wyoming to Chile.
In a private mail, A. Mayor (author of the Melyrid families's group in American Beetles II: 294-295) told me he had recognized several new taxa of these genera among museums'undetermined material.
If I suppose right, the photographs of the specimen are of a female new species. Check the tarsi ended with claw devoided of appendage or tooth.
Robert Constantin (French taxonomist of this group, World level now)

 
Thank you so much, Robert.
Would Dr. Mayor consent to view these images to see if they are similar to new taxa he has uncovered in museums? If he needs to view this photographed specimen, it might be available on loan from New Mexico State University, Las Cruces. Greg Forbes is my main contact there.

 
Unidentified Melyrid from New Mexico
Jim,
I agree with Robert that this is a species of Scuromanius. The name is a rearrangement of Mauroniscus, another genus in this group. The specimen you have may be Scuromanius facetus (Casey). I have seen a long series of this species from southern Utah, and it is known from Arizona and New Mexico. The taxonomic status of the family Mauroniscidae is still unsettled, and is probably best treated as a subfamily of Dasytidae for the moment. As with your specimen adults are often found on desert flowers in the late summer and fall.

 
Excellent! Thank you, Adriean.
Greg Forbes tells me the specimen *is* available but you seem to think this is a known species so I doubt you will want to examine it.

As for treatment of Mauroniscidae, have the dasytines now been elevated to family status, making the new group Mauroniscinae? Currently we have Dasytinae positioned under Melyridae, which I suppose would make the new group Mauroniscini.
