Organ identity and boundaries Determine whether a reported head structure belongs to this registered organ concept.
Anatomical recognition
Locate the candidate in the head and establish its observed boundaries.
Postantennal candidate
Record head landmarks and bilateral observations before assigning an organ identity.
- Where is the candidate relative to the antennal socket and other identifiable head landmarks? definition
- What corresponding structure is visible on the opposite side, and could damage or orientation explain a mismatch? measurement
Anatomical lookalikes
Separate the organ from nearby eyes, cuticular features and supporting articulations.
Tentorial and ocular exclusion
Require evidence that the candidate is neither an ocellus nor a head-support articulation; the latter has caused published misidentifications in Polydesmida. [Primary anatomical study](https://doi.org/10.3897/zookeys.930.48438)
- Does internal examination connect the apparent pit to the tentorium rather than to sensory tissue? boundary
- Which anatomical observations distinguish this candidate from an adjacent ocellus or ordinary cuticular depression? boundary
Sensory apparatus morphology Describe the external structure and the internal evidence for a sensory apparatus.
External form and scale
Capture calibrated organ shape without conflating orientation or preparation effects with biological differences.
Rim, opening and covering
Document the observed outline, surface covering and dimensions separately for each side.
- What are the organ's length, width and opening dimensions in a specified viewing plane? measurement
- Which rim or covering features remain identifiable across views, and which may result from preparation? measurement
Internal sensory organization
Assess receptor tissue and neural connections using appropriately resolved observations.
Receptors and innervation
Separate directly observed sensory components from anatomical expectations imported from another species.
- What receptor cells or associated tissue are actually resolved, and by which imaging or sectioning method? provenance
- Has a nerve connection been traced from this organ, and where does the direct observation end? boundary
Occurrence and comparative interpretation Relate organ observations to specimens and taxa without assuming universal presence or common ancestry.
Specimen-level occurrence
Record the material examined and the strength of presence or absence evidence.
Presence versus nondetection
Keep an unsuccessful search distinct from anatomically supported absence.
- Which identified specimens, developmental stages and head sides were examined? provenance
- Was resolution and anatomical coverage sufficient to support absence rather than nondetection? measurement
Terminology and homology
Manage cross-taxon comparisons without turning shared names into proof of equivalence.
Comparative character assignment
Track the anatomical meaning of each author's terminology and the evidence supporting comparison.
- Does this source use temporal organ or postantennal organ for the same bounded structure modeled here? definition
- What evidence beyond position and naming supports homology between the compared organs? boundary
Function, condition and investigation Assess organ condition and investigate sensory roles through discriminating observations.
Modality and response
Represent candidate stimuli as testable hypotheses with organ-specific evidence requirements.
Localized sensory evidence
Evaluate proposed responses to humidity, chemical or mechanical stimuli without assigning any modality universally.
- Which stimulus was varied, over what range, and what response was measured directly at the organ or its nerve? measurement
- What controls distinguish the candidate organ's contribution from antennal, ocular or other sensory responses? boundary
Integrity and next observation
Use organ condition and the unresolved identification question to select further examination.
Interpretable organ condition
Record obstruction, injury and preparation effects before treating appearance or response as representative.
- Could damage, contamination, fixation or collapse explain the observed form or missing response? measurement
- Would additional surface imaging, internal reconstruction or physiological recording best resolve the specific uncertainty? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
The organ of Tömösváry is a paired sensory structure on the head near the antennal bases in certain myriapods, whose function remains incompletely resolved and may differ among groups.
In scope
- Identification of candidate organs relative to antennal bases and other head landmarks
- External morphology, internal sensory anatomy and documented innervation
- Presence, absence, bilateral variation and condition in identified specimens
- Evidence supporting proposed sensory modalities
- Taxon-specific terminology and explicit limits on homology claims
Out of scope
- Whole-organism taxonomy, distribution and conservation assessments
- Complete anatomy and physiology of antennae, eyes and other sensory organs
- Head-capsule mechanics and tentorial anatomy beyond differential identification
- Whole-animal habitat preferences and behaviour except as evidence in organ-specific experiments
- Independent models of hexapod postantennal organs or pseudocelli whose equivalence remains disputed
Why it exists Filled
Enable an agent to recognize an organ of Tömösváry, document its anatomical condition, and evaluate sensory-function claims without confusing it with neighbouring head structures.
Distinguishing features Filled
- Check for a discrete structure behind or near the antennal base in the position documented for the examined taxon; head position alone is insufficient for identification.
- Examine corresponding left and right head regions because the organ is described as paired, while recording unilateral damage or incomplete visibility separately.
- Distinguish the candidate from an ocellus using structural evidence rather than its rounded appearance or proximity to eyes.
- Exclude a tentorial articulation: a study of four polydesmidan species identified the supposed organ as part of the head's supporting articulation. [Primary anatomical study](https://doi.org/10.3897/zookeys.930.48438)
- Require anatomical support before equating structures called temporal or postantennal organs across different arthropod groups.
What robots and AI may and may not do Filled
Must not
- Present a proposed function as established fact.
- Harm or kill living myriapods for observation when preserved specimens would serve.
- Collect protected species or from protected habitats without permission.
- Apply findings from one group of myriapods to all groups without evidence.
Only with a human decision
- Collecting live animals for study.
- Experiments on living animals.
May
- Describe the organ of Tomosvary and its place on the heads of certain myriapods, citing sources.
- State clearly that its function is not fully resolved.
Moral aspects Filled
- Invertebrate welfare still matters in collection and experiment.
- Overstating unresolved science misleads students and readers.
Who is affected
- Myriapods
- Researchers and students
- Habitats where they are collected
Owners Filled
Steward
