Conservation status

Western Australia, WA Threatened and Priority Fauna List: Priority 1.

Seasonal planning

Species-specific seasonal activity, breeding and movement information is not available. Use year-round precautionary planning rather than assuming any period is low risk.

Known seasonality: Not recorded.

Planning implication: Schedule checks and maintain detection procedures throughout the year.

Month-specific phenology is not known.

  • Precautionary survey and works planning: Year-round planning window only; no seasonal activity pattern is known for this species.

Identification: Appearance and size

The Fan-winged Katydid (Champion Bay) is a katydid, but its field identification features have not been documented.

Psacadonotus seriatus is an insect in the family Tettigoniidae. Its colour, shape, wings, distinguishing features and size have not been documented.

  • Do not rely on the common name alone to identify an individual.

Identification: Similar species

Other species are listed in the genus Psacadonotus, but field characters for distinguishing this species from other katydids have not been documented.

Identification: Field signs

Species-specific calls, eggs, nymphs, feeding signs, shelters and other field signs have not been documented.

Distribution: Known range

Known location information is sparse and does not provide a mapped range.

The type specimen is recorded from Derby, Western Australia. The species is endemic to Australia, but no additional locality records are available.

  • Atlas of Living Australia records show no public Western Australian coordinates.

Distribution: WA listing region

The DBCA list flags the Midwest region. The species is Priority 1, is poorly known and is known from few locations, with none on conservation lands.

  • No precise boundaries or other WA occurrence localities are recorded.

Distribution: Listing context

Priority 1 is a DBCA priority category, not a listing under the Biodiversity Conservation Act 2016. The species has no national listing.

Habitat: Recorded habitat

The species' habitat has not been documented.

Vegetation, landform, soil, moisture conditions and other habitat features used by Psacadonotus seriatus have not been recorded.

Habitat: Site assessment

Do not infer suitable habitat from the common name or type locality. Record the vegetation and site conditions during project surveys, and treat potential habitat as uncertain unless supported by local evidence.

Foraging habitat: Diet and feeding

The species' diet, feeding behaviour and foraging habitat have not been documented.

Food plants, prey, feeding signs and foraging behaviour are not recorded for Psacadonotus seriatus.

Foraging habitat: Precaution during site checks

Do not treat plant associations or feeding signs as species-specific without confirmation. If an individual is found, record the immediate site context and seek identification advice.

Breeding habitat: Breeding information

Breeding biology and breeding habitat are poorly known.

Egg-laying sites, development stages, breeding season and number of generations have not been recorded for this species.

Breeding habitat: Works planning

Do not assume any month or site feature is free of breeding activity. If an individual or possible eggs or nymphs are found, pause disturbance in the immediate area and seek advice from a suitably qualified ecologist.

Sheltering habitat: Shelter information

Sheltering behaviour has not been documented.

Shelter types, resting places, seasonal refuges and hiding behaviour are not recorded for Psacadonotus seriatus.

Sheltering habitat: Precaution

During inspections, check vegetation and ground material carefully before moving or clearing them. This is a general precaution for small terrestrial invertebrates, not a known sheltering behaviour of this species.

Threats: Known pressures

Specific threats to this species have not been identified.

Threats, population trends and responses to land disturbance have not been documented for Psacadonotus seriatus.

Threats: Risk management

Given the species' limited known locations, do not assume it is absent from a development site because no records are available. Manage uncertainty through targeted checks, careful clearing and prompt escalation of any possible detection.

Survey methodology: 1. Desktop assessment

No species-specific survey method or detectability information is available. Use a cautious, documented approach and seek expert identification where needed.

Review the development footprint and site records for relevant invertebrate information. The known information includes a Derby type locality and a DBCA Midwest listing-region flag, but no mapped occurrence coordinates or habitat description.

Survey methodology: 2. Field inspection

Have a suitably experienced invertebrate ecologist inspect vegetation and ground material in areas scheduled for disturbance, using careful visual searches and close inspection as appropriate. These are general invertebrate survey precautions, not a validated method for this species.

Survey methodology: 3. Records and identification

Photograph possible detections in place where practical, record the date and precise location, and document the surrounding site conditions. Do not identify the species from the common name alone; seek specialist confirmation and report findings through the project's agreed fauna procedures.

Vegetation associations

Source-checked associations and automatically indexed candidates are separated below. An association does not establish site presence, preference or dependence.

No species-specific vegetation association has been indexed or source-checked in this evidence library. This is an evidence gap, not evidence of no association.

Ecosystem associations

Source-checked associations and automatically indexed candidates are separated below. An association does not establish site presence, preference or dependence.

No species-specific ecosystem association has been indexed or source-checked in this evidence library. This is an evidence gap, not evidence of no association.

Fauna records and mapped habitat: Not yet analysed

Record locations can be overlaid with mapping, but record frequency alone does not measure habitat preference. No species is excluded from desktop assessments by this analysis.

No quality-controlled record-to-map analysis has been completed for this species. The existing generalised distribution dots and indicative range polygons have not been treated as precise occurrence coordinates.

A defensible run needs dated, independently attributable records, coordinate uncertainty, duplicate and captive-record checks, layer versions and regional scope. Preference and absence require additional survey-effort and detection evidence.

Habitat limitations and contrary evidence: No supported exclusion recorded

Not recorded is not the same as cannot occur. Low suitability, resident habitat, breeding habitat and occasional movement are different conclusions.

This library has not established a vegetation, ecosystem or soil-type exclusion for this species. This does not mean all habitat is suitable; the evidence needed to justify an exclusion has not been assembled.

Habitat limitations and contrary evidence: Before using a negative association

  • Confirm the taxon, geographic region, life stage and habitat function covered by the evidence.
  • Check survey methods, season, repeated effort and detectability before interpreting non-detection.
  • Investigate credible contradictory records and microhabitats absent from broad mapping.
  • Do not convert a missing map class, low record count or failed data request into species absence.

Before habitat disturbance: 1. Plan and brief

The species' habitat and seasonality are unknown, so project planning should allow for uncertainty before clearing starts.

Confirm the disturbance footprint, timing, fauna responsibilities and escalation process with the project ecologist. Brief crews that the species is assigned DBCA Priority 1 and that its ecology and identification are poorly documented.

Before habitat disturbance: 2. Check and mark

Arrange a pre-clearance inspection of the proposed work area and mark any areas to be avoided or checked further. Do not use assumed habitat or a particular season to rule out the species.

During habitat disturbance: 1. Clear carefully

Proceed cautiously and keep a clear response process in place because the species' behaviour during disturbance is not known.

Keep clearing within the approved footprint and use staged, controlled methods where practicable. Inspect vegetation and ground material before moving it, as a general precaution for small terrestrial invertebrates.

During habitat disturbance: 2. Respond to detections

If a possible individual is found, pause work in the immediate area, protect it from further disturbance and contact the project ecologist for identification and direction. Record the location and circumstances, and do not handle or relocate it unless authorised and appropriately qualified.

After habitat disturbance: 1. Record outcomes

Document outcomes and review any detections or unexpected site conditions after clearing.

Keep survey and clearing records, including locations inspected, dates, methods, possible detections and identification outcomes. Submit confirmed records through the project's agreed reporting pathway.

After habitat disturbance: 2. Review controls

If the species is detected, or identification remains uncertain, review the work controls with the project ecologist before disturbance resumes in the affected area. Do not assume that a single non-detection establishes absence.

Rehabilitation actions: 1. Restore the site

The species' habitat requirements and response to rehabilitation are unknown, so restoration targets cannot be specified for it.

Where rehabilitation is required, use the project's approved local restoration objectives and avoid unsupported species-specific habitat assumptions. Retain site information and records that may help guide future assessment.

Rehabilitation actions: 2. Monitor and adapt

Document rehabilitation actions and follow-up checks. If the species was detected at the site, consult the project ecologist about whether additional monitoring or changes to site management are warranted.
