Question about an Arthropod Anatomy Ontology and NTR: Haller's organ

Hello Uberon Team,

Ticks (Acari) are quite interesting, and recent publications are providing increasingly detailed transcriptomic data, for example see
This also made me wonder whether there is, or is planned to be, an Arthropod Anatomy Ontology.

For example, I noticed the following editor note in UBERON:0002536:

name: arthropod sensillum
property_value: editor_note "this term should be ceded to the arthropod anatomy ontology" xsd:string

Similarly, UBERON:0000916 (abdomen) contains this note:

"Vertebrate specific. In arthropods 'abdomen' is the most distal section of the body which lies behind the thorax or cephalothorax. If need be we can introduce some grouping class"

In OLS, I can find OArCS, an ontology describing the arthropod circulatory system, but I could not find a broader ontology covering arthropod anatomy.

Do you know whether a general Arthropod Anatomy Ontology is currently being developed or planned? If so, which group or team is working on it?

More specifically, I am interested in representing structures such as Haller's organ in ticks. For example, I was considering something along the following lines:

id: UBERON:xxxxxxx
name: Haller's organ
def: "A group of chemosensitive cells concentrated on the tarsus of the forelegs, which ticks wave in front of them as with insect antennae in an alternating up and down fashion, rather than using them for walking." [Wikipedia:Haller%27s_organ]
is_a: UBERON:0000020 ! sense organ
relationship: in_taxon NCBITaxon:6933 ! Acari
relationship: part_of UBERON:6000002 ! arthropod tagma

I would appreciate any guidance on whether such tick/arthropod-specific anatomical structures should be represented directly in UBERON, or whether there is an appropriate arthropod anatomy ontology that should be used instead.

Many thanks for your help!

Anne

Review the editor notes for UBERON:0002536 and UBERON:0000916, then compare the proposed Haller's organ representation with OArCS and the cited PubMed publication. This is done when the appropriate ontology placement and responsible group are established, or the required next step is clearly identified.
