Tityopsis sheylae
Orange Cave Scorpion: Advanced Care Guide
Keeper Snapshot: Humidity is the non-negotiable control. The describing authors report at genus scope that Tityopsis critically dehydrate and die within 36 hours unless ambient air RH stays above 85%. That supports continuously humid air, not saturated substrate or an airtight enclosure. Use evenly damp moisture-retentive substrate with no standing water, minimal but functional cross-ventilation, rock or cork cover, and an escape-proof lid. No numeric temperature optimum exists; this species was more abundant in cooler cave chambers and scarce in the hottest, so normal cool-to-moderate room conditions without direct heat are Big Z house practice. No hand contact: no clinical or toxinology record exists for this genus, so what a sting would do is genuinely unrecorded rather than known to be mild, and Big Z's keeps the boundary on that uncertainty alone. The Advanced lane is set by the humidity window, not by a venom claim. - Big Z
Group: ScorpionsDifficulty: Spice 4: AdvancedSetup: Small high-humidity cave setup: flat limestone or cork cover over evenly damp moisture-retentive substrate, ambient air RH held continuously above 85%, with small functional cross-vents. Never sealed airtight and never waterlogged.Handling: No contact. Not because the sting is known to be dangerous, but because nobody has established what this genus's venom does, and an absence of study is not evidence of a mild sting. Catch cup and long tongs only.
Use This Guide Safely
- Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
- Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
- Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.
Quick Snapshot
| Temperature | No numeric optimum is published. In the type cave 42 T. sheylae were found in the colder chambers and corridors against only 3 in the hottest chamber, but no chamber temperature was ever measured, and that gradient confounds temperature with humidity, light and bat guano - the cool end is also the drier, guano-free end. Treat it as an ecological signal, not a thermal preference curve. Normal cool-to-moderate room conditions without a direct heat source are Big Z house practice. |
|---|---|
| Humidity | Maintain ambient air RH above 85% continuously. This threshold is genus-level primary evidence: published authors report Tityopsis dehydrate and die within 36 hours below it. Use moisture-retentive substrate kept evenly damp, not saturated or standing wet, with enough small cross-ventilation to prevent stagnant air while retaining humidity. |
| Setup Type | Small high-humidity cave setup: flat limestone or cork cover over evenly damp moisture-retentive substrate, ambient air RH held continuously above 85%, with small functional cross-vents. Never sealed airtight and never waterlogged. |
| Substrate | Use evenly damp, moisture-retentive soil/coir or a stable equivalent with flat rock or cork cover. Exact mix and depth are Big Z construction choices. Do not waterlog the substrate or leave standing water. The primary evidence concerns ambient RH above 85%, not saturated substrate or a sealed vessel. |
| Feeding | Offer very small soft-bodied prey or pre-killed portions at a cautious recorded Big Z house cadence. Mealworms, roach nymphs, and other prey are reported for captive congeners, not T. sheylae. No species feeding trial, prey-size rule, or validated cadence was found; remove leftovers and stop live prey around molt. |
| Care Difficulty | Spice 4: Advanced |
| Handling | No contact. Not because the sting is known to be dangerous, but because nobody has established what this genus's venom does, and an absence of study is not evidence of a mild sting. Catch cup and long tongs only. |
Humidity zones: Very Low under 30% - Low 30-60% - Low-Moderate 40-70% - Moderate 60-80% - Moderate-High 70-85% - High 80%+ - Very High 90%+
Enclosure Format / Size Class
- Juvenile (6-13 mm as supplied): exact instar unknown; individual humid micro-enclosure, evenly damp substrate, flat cover, functional micro-ventilation, and escape-proof openings
- Larger juvenile: individual high-humidity enclosure with rock/cork cover, no standing water, and a safely sized open dish only if drowning risk can be controlled
- Adult (published total length 23.6-26.8 mm males and 32.1-34.0 mm females): secure individual high-humidity enclosure with evenly damp substrate, functional ventilation, and multiple rock/cork retreats
Warnings First
- The >85% requirement is ambient-air RH at genus scope. The authors report critical dehydration and death within 36 hours below it; they did not prescribe saturated substrate, standing water, or an airtight vessel.
- The same paper argues against chasing saturation: in the type cave's hottest, water-saturated, guano-covered corridors only 3 T. sheylae have ever been found, while 42 came from the colder chambers the authors expressly describe as 'less humid' (Euscorpius 304, p. 37). Above 85% RH is a floor to clear, not a target of 100%.
- The 85% / 36-hour figure is the describing authors' husbandry assertion, not a controlled trial: Euscorpius 304 reports no RH instrument, method, sample size, or tested gradient. In the same paper a congener's cage kept 'under drier conditions for several days' produced only gradual paling that reversed once humidity was raised, with no deaths reported. Treat a scorpion going paler as an early drying warning and correct the air humidity before it becomes an emergency.
- No numeric temperature optimum, ventilation rate, substrate depth, or T. sheylae feeding trial was found. Cooler-chamber abundance is an ecological signal, not a tested preference curve.
- The 6-13 mm supplied length does not establish first-to-third instar. These are juveniles, exact instar unknown.
- No toxinological, clinical, or sting-severity record exists for any Tityopsis species. UniProtKB returns zero entries and PubMed zero results, checked 2026-08-15, and the 40-page 2020 revision makes no venom statement. That is an absence of study, not a finding that the sting is mild, and Big Z's infers nothing in either direction from it. The genus was erected inside Tityus and still sits in subfamily Tityinae alongside it. No hand contact, and the Spice 4 lane is set by the humidity window rather than by any venom claim.
- A suspected sting is an emergency: seek professional emergency care immediately and contact the appropriate poison service. This guide gives no treatment protocol.
- Known occurrence is one cave. A Mohamed bin Zayed Species Conservation Fund project found fewer than ten target individuals, including two adults. The project leader, Tomas Michel Rodriguez Cabrera, writes that the species 'most certainly fulfill the IUCN criteria in the category of Critically Endangered' - his stated view on the project page, not a formal assessment. No IUCN Red List assessment was located in Version 2026-1.
Simple Care
- House one animal per enclosure.
- Keep ambient air RH above 85% continuously; this is genus-level primary evidence.
- Keep moisture-retentive substrate evenly damp, never saturated or standing wet.
- Use minimal but functional cross-ventilation and monitor RH at the animal's level.
- Use cool-to-moderate room conditions without direct heat; no numeric optimum was published.
- Provide flat rock or cork cover and an escape-proof lid.
- Offer tiny soft-bodied or pre-killed prey at a recorded house cadence; no species schedule exists.
- No hand contact. Catch cup and long tongs only.
Advanced Keeper Notes
Enclosure & Microclimate
- Most T. sheylae were found hidden under rocks in the cooler chambers (42 animals); only the few in the deepest hot, saturated corridors (3 animals) sat exposed on walls and floor. The genus account also states all Tityopsis need shady, humid places with plenty of refuges - rocks, leaf litter, rotten logs. Flat rock or cork cover is therefore directly supported by the primary source, not a conservative guess. Exact enclosure geometry and substrate recipe remain Big Z house choices.
- The >85% RH observation covers all Tityopsis maintained by the authors, wild-caught and captive-born. It is strong genus-level evidence but not a controlled T. sheylae threshold experiment.
- High air humidity is not the same as saturation. Keep substrate evenly damp without free water and retain minimal functional cross-ventilation to prevent stagnant air.
- The species was most abundant in cooler chambers and scarce in the hottest, but no chamber temperatures were reported. Avoid direct heat and record actual conditions.
- Escape-proof openings matter because the species occupies vertical cave surfaces; no size-specific climbing experiment was performed.
Feeding, Growth & Maintenance
- Published captive prey observations concern other Tityopsis species. Small soft-bodied prey is therefore a congeneric starting point, not T. sheylae evidence.
- No species cadence or prey-size rule was found. Use a cautious recorded house schedule, remove leftovers promptly, and adjust from intake and body condition.
- Genus-level development summaries and congeneric neonatal timing do not stage this shipment. Supplier length alone does not establish instar.
Possible Origin / Range
- Likely native range: Known only from the type locality: Cueva del Indio, Mogote La Jaula, Escaleras de Jaruco, Tapaste, on the border of San Jose de Las Lajas and Jaruco Municipalities, Mayabeque Province, Cuba, at 190 m. The cave sits in the southern mogotes of Escaleras de Jaruco, a 15 x 5 km karstic limestone plateau isolated in the Habana-Matanzas Plain. The genus Tityopsis is endemic to western Cuba (Pinar del Rio, Artemisa, La Habana, Mayabeque and Matanzas Provinces) and is not known from Isla de la Juventud, from adjacent islets, or from outside Cuba; the one apparent exception, T. aliciae from Oaxaca, Mexico, was removed from the genus when Chaneke was described in 2014, so any Mexican record found while re-researching this species is obsolete. Repeated intensive searches in the forest outside the cave and in other mogotes of the same plateau produced no live animals, carcasses or exuviae, but those searches targeted epigean (surface) occurrence and no systematic survey of other caves is reported. The authors call it a true troglobite in the text and 'apparently a troglobite' in the Distribution section, so this guide calls it a presumed obligate cave-dweller. This is a known-occurrence statement, not a population estimate.
- Habitat translation: A single-cave, rock-surface scorpion requiring continuously humid air at genus scope. Translate that into an escape-proof micro-enclosure with evenly damp moisture-retentive substrate, flat rock or cork cover, no standing water, minimal functional cross-ventilation, and RH monitoring above 85%. Use cool-to-moderate room conditions without direct heat. Exact mix, depth, airflow, and feeding cadence are Big Z house choices, not measured species optima.
Advanced Keeper Details
- The species authority is Tityopsis sheylae Teruel & Rodriguez-Cabrera, 2020 (Euscorpius 304). The genus authority is Tityopsis Armas, 1974, erected as the subgenus Tityus (Tityopsis) and raised to genus rank by Armas, 1984.
- Prendini 2026 (Megataxa 19(2):270-378) records Tityopsis with 7 extant species and places it in subfamily Tityinae Kraepelin, 1905, stat. rev., the same subfamily as Tityus, Centruroides and Alayotityus. The Scorpion Files (updated 14.08.2026) lists the same seven. GBIF's backbone still shows only six because T. rolandoi (2024) has not been ingested; seven is current and six is a lag, not a correction.
- The 2020 revision identified 'not less than eight new taxa, which raise the diversity of this genus to at least 10 species'. Four of those eight were described in Part 1 (mulata, pumila, canizaresorum, sheylae); the other four are still undescribed, and the authors flagged further populations under study that may add more. Part 2 was never published and Rolando Teruel died in 2023.
- Adult total length is 23.62-26.76 mm in males and 32.11-34.00 mm in females, measured from four type specimens (Table 3); the diagnosis rounds these to 24-27 mm and 32-34 mm. Big Z's stock at 6-13 mm is far below the smallest measured adult and is juvenile, exact instar unknown.
- The description gives a light yellowish-brown, essentially immaculate adult and a pale yellowish-brown juvenile. The one Tityopsis described with an orange base colour is T. pumila. 'Orange Cave Scorpion' is a trade-search name only, not a diagnostic colour statement for this species.
- VENOM: no toxinological data exist for any Tityopsis species. Verified 2026-08-15 - UniProtKB returns zero entries for 'Tityopsis' and PubMed returns zero results, and the 40-page 2020 revision reports natural history at length while making no venom, toxicity or medical statement. Tityopsis was erected inside Tityus and still sits in Tityinae with Tityus, a genus containing medically significant species. Big Z's treats it as no-contact because the venom is unstudied, not because it is known to be dangerous. Nothing published supports calling it harmless or mild, in either direction.
- Known occurrence is one cave. A Mohamed bin Zayed Species Conservation Fund project found fewer than ten target individuals including two adults. The project leader, Tomas Michel Rodriguez Cabrera, states the species 'most certainly fulfill the IUCN criteria in the category of Critically Endangered' - his stated view on the project page, not a formal assessment. No IUCN Red List assessment was located in Version 2026-1.
- GBIF returns zero occurrence records for T. sheylae, by name and by taxonKey 10802148, and 13 for the whole genus. That is a database-coverage result, not evidence of abundance, rarity, decline or conservation status.
