Received this specimen (collected during 2012) from a colleague for my studies... Loc: Kerala; there are two species known from India (both species coming from Kerala) viz., Notomulciber (Micromulciber) travancorensis Breuning, 1958 and Notomulciber (Micromulciber) decemmaculatus Breuning, 1942... obviously it is not the latter species...
I do not know the former species nor have the original description to compare... suggestions are welcome on the identity...
Thank you

How do one separate Micromulciber and Grynex...
Following the description of Pascoe (1867: 453) here Micromulciber is defined to have the elytral apex obliquely emarginate and 'ending externally in a stout point' and Pascoe (1888: 502) defines here Grynex as having elytral apex obliquely incised and 'tapering to an obtuse point at apex'...the description of other characters also seems to fit one another...are there real characters by which these two are differentiated??...Please clarify if I'm mistaken...

According to Breuning's revision (1950), Notomulciber shows a rounded prosternum, while Grynex shows a prosternum vertically truncated posteriorly.

Have you got that revision?

In Breuning, 1950. Revision des Homonoeini. description of Paragrynex ochreosparsus Breuning, 1940 fits quite well with your specimen.

The specimen completely agrees with the genus description but there are some striking features in the specimen posted here compared to the only species known within this genus...as you can see in the lateral aspect of the specimen (image attached) I could enlist following characters not mentioned in the description of the species ochreosparsus...
  • There are distinct tubercles on the humeral prominence
  • there is almost circular greyish yellow spot, a quarter away from the humeral prominence
  • in the same line, there is an oblong short band present just behind the middle, followed by a greyish longitudinal line approaching towards elytral apex
  • lateral margins of elytra provided with interrupted band of greyish yellow pubescence

So, considering the above points, whether it remains the same species?

I'll check my database to find a picture of this sps later. Breuning's key to differentiate the Homonoenini genera you can forget completely is like a lottery .

... and I proposed this name by reading the description, but I haven't seen holotype to prove anything.

Original description from BREUNING S., 1940.Novae species Cerambycidarum. IX. Folia Zoologica et Hydrobiologica, Riga 10 (1): 115-214.

I do not know if the German text is the same as French one.

I think both text (German and French) speak about the same characters (courtesy of google translator)...

from the descriptions ok you can find in many cases a satisfied ID but the keys are almost useless.
