Orconectes deanae Reimer and Jester 1975
Bibliographic record
Abstract
Orconectes deanae Reimer and Jester, 1975: Conchas Crayfish General charateristics. Adults rarely exceed 85 mm in total length. The rostrum has distinct spines, a slight central depression, and the areola is closed. Chelae are long and slender, and the dactyl is nearly twice as long as the palm. In form I males, gonopods terminate in two strongly curved processes. The central projection is bent at a 45° angle to the shaft, and the mesial process bent at a 90° angle to shaft. In females, the annulus ventralis is subelliptical and is wider than long (Reimer & Jester, 1975). Life coloration. The background color is light brown to dark brown (Figure 47). The abdomen is slightly darker than the carapace. Dark speckling on dorsal side of chelae is present. Ventral side is off-white. Similar species. In Oklahoma, O. deanae closely resembles O. palmeri longimanus. It differs from O. palmeri longimanus in the curvature of the gonopods of form I males. In O. deanae, the mesial processes are curved at approximately a 90° angle to the shaft, while it is never curved to that extent in O. palmeri longimanus. Furthermore, the central projection of gonopods in O. deanae represents no more than 1/5 of the total appendage length, while it represents at least 1/4 of the total length in O. palmeri longimanus (Figure in couplet 22). Distribution and habitat. Orconectes deanae was originally described from Conchas Reservoir in New Mexico. Conchas Reservoir is an impoundment in the northern reaches of the Canadian River. In Oklahoma, O. deanae is known form the North Canadian River drainage and the Arkansas River near its confluence with the North Canadian River. Our ecological niche model also indicated that the western portion of the Red River drainage provides suitable environmental conditions (Figure 48). Orconectes deanae is mostly found in lentic habitats along the North Canadian River. It occupies debris piles in turbid, muddy waters. Life history. Details about the life history of O. deanae remain unclear. Most specimens have been collected from man-made ponds and reservoirs and is a tertiary burrower. Form I males and females have been collected in January and juveniles in July (Reimer & Jester, 1975). We have collected females and form II males in October. Syntopic species. Orconectes causeyi, Orconectes nais. Conservation status. AFS: Currently Stable; Heritage Rank: Apparently Secure (G4); IUCN: Least Concern; ODWC: Not Listed. Additional resources. Johnson (2010).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
