If you look up any of the lost species featured in the pages of our October-December 2007 feature Presumed Extinct, you’re likely to find just that—the words presumed extinct followed by a brief natural history account, if you’re lucky. In the hope that these lost species might someday become Lazarus species—plants and wildlife that rise up from the dead—we’ve put together a field guide to help Bay Area naturalists in their search for the next Holy Grail.
While the likelihood of finding a lotis blue butterfly or Pitkin Marsh Indian paintbrush in your backyard or on a weekend hike are slim-to-none (both are restricted to private property), there’s no reason why a mail carrier might not stumble across a Palo Alto lost thistle on her way to the post office, or an itinerant hiker might not hit upon a Strohbeen’s Parnassian butterfly in the Santa Cruz Mountains. Or, realistically, why it’s worthwhile to reach for your field guide the next time your housecat leaves a present on the doorstep—it could be a Berkeley kangaroo rat! And then there’s Rich Mooi’s offer to those interested in visiting the California Academy of Sciences to learn about the Bay’s benthic creatures, a free ticket to paw through jars of mud in search of the San Francisco horseshoe shrimp. So read up; we’re counting on you to keep your eyes peeled!
SPECIES: Strohbeen’s Parnassian butterfly (Parnassius clodius strohbeeni)
LISTING STATUS: none
FIRST/LAST RECORDED: 1923/~1956
RANGE: known only from the Santa Cruz Mountains in Santa Cruz County
HABITAT: host plant is western bleeding heart (Dicentra formosa); redwood forests, well-lit canyon bottoms, stream zones
FIELD NOTES: of the Parnassian butterflies (P. clodius), Strohbeen’s Parnassian is a lighter sub-species restricted to the Santa Cruz Mountains; its closest cousins are found in the high inner North Coast Range, the Klamath Mountains, and the west slope of the Sierra Nevada; the Strohbeen’s Parnassian’s flight period is late May to early July

- Lotis blue butterfly (Lycaeides idas lotis). Illustration by DevinCecil-Wishing.”
SPECIES: lotis blue butterfly (Lycaeides idas lotis)
LISTING STATUS: federally endangered
FIRST/LAST RECORDED: 1879/1983
RANGE: scattered locations throughout Mendocino and Sonoma County; last known from a single location on PG&E land in Mendocino County’s Pygmy Forest
HABITAT: suspected host plant is seaside bird’s-foot trefoil (Lotus formosissimus); wet meadows, spagnum-willow bogs
FIELD NOTES: the lotis blue is often described as a larger version of its fellow blue, the Melissa blue butterfly (Lycaeides melissa); the lotis blue’s flight period is mid-April to June

- Clear Lake splittail (Pogonichthys ciscoides) illustration byDevin Cecil-Wishing.
SPECIES: Clear Lake splittail (Pogonichthys ciscoides)
LISTING STATUS: none
FIRST/LAST RECORDED: ~1930/~1970
RANGE: known only from Clear Lake in Lake County
HABITAT: Clear Lake and its tributary waters, plus an outlying record from Cache Creek (downstream of Clear Lake)
FIELD NOTES: a lake-bound cousin of the Sacramento splittail (P. macrolepidotus), Clear Lake’s shoreline splittail wasn’t officially described until 1973, approximately the time it went extinct; aside from geographic isolation, the differences between the species are morphological; compared to the Sacramento splittail, the Clear Lake splittail has more gill rakers, more lateral line scales, smaller fins, a terminal mouth with absent or reduced barbels, and a relatively symmetrical tail fin

SPECIES: thicktail chub (Gila crassicauda)
LISTING STATUS: none
FIRST/LAST RECORDED: present in Native American middens/1957
RANGE: reported specifically in Sacramento River, Putah Creek, Pajaro-Salinas drainage, Clear Lake, San Francisco Bay, Coyote Creek, Central Valley lowlands, and Bay tributary streams
HABITAT: lowland lakes, sloughs, slow-moving river stretches, and surface waters of the San Francisco Bay
FIELD NOTES: thicktail chub remains are reportedly common in Native American middens along the Sacramento River, and have been recovered from 19th-century Chinese privies in San Francisco’s Mission District; in the 19th century the fish was commonly sold in San Francisco fish markets and was served in Sacramento saloons; compared to other chub, the thicktail chub is a heavy-bodied fish with a small, cone-shaped head, greenish brown to purplish black back, and yellowish sides and belly

- Illustration based on Shasta crayfish photo by B. Moose Peterson/WRP
SPECIES: sooty crayfish (Pacifastacus nigrescens)
LISTING STATUS: none
FIRST/LAST RECORDED: 1857/late 1800S
RANGE: reported specifically in Alameda Creek, Coyote Creek, Steamboat Slough, and other Bay tributary streams
HABITAT: freshwater Bay tributary streams
FIELD NOTES: the sooty crayfish hasn’t been seen in over 100 years; the sooty crayfish closely resembles its cousin the Shasta crayfish (Pacifastacus fortis) but is blackish, smaller in size (4 inches long), and has more slender, hairless hands (claws)

SPECIES: San Francisco horseshoe shrimp (Lightiella serendipita)
LISTING STATUS: none
FIRST/LAST RECORDED: 1961/1988
RANGE: known only from San Francisco Bay at Point Richmond, Brooks Island, Coyote Point
HABITAT: muddy sand bottom
FIELD NOTES: although extensive sampling has been done to rediscover this shrimp at its type locality and other collection locations, “searching” for this species amounts to sorting through Bay mud; mud-raker Richard Mooi of the California Academy of Sciences has generously offered would-be shrimp seekers the opportunity to pick through jars of mud—with the proper training, of course—to make sure no horseshoe shrimp have been overlooked— Reach Mooi at (415)321-8270.

SPECIES: Palo Alto lost thistle (Cirsium praeteriens)
LISTING STATUS: CNPS List 1A (presumed extinct in California)
FIRST/LAST RECORDED: 1897/1901
RANGE: known only from Palo Alto in Santa Clara County
HABITAT: unknown
FIELD NOTES: with nothing but “Palo Alto” recorded for the type specimen’s collection location, botanists know nothing about this thistle’s preferred habitat; notes to the effect that the species represents an introduction from the Old World are unsubstantiated and the species is still recognized today as a native California thistle

SPECIES: Pitkin Marsh Indian paintbrush (Castilleja uliginosa)
LISTING STATUS: state Endangered; CNPS List 1A (presumed extinct in California)
FIRST/LAST RECORDED: 1937/1986
RANGE: Pitkin Marsh, Trembley’s Marsh in Sonoma County
HABITAT: marshy meadows
FIELD NOTES: the Pitkin Marsh Indian paintbrush grows solely in association with rhododendron plants in a type of hemiparasitic relationship; all known plants were reported on private land, which has prevented further surveys to determine if any unrecorded plants have persisted

SPECIES: Berkeley kangaroo rat (Dipodomys heermanni berkeleyensis)
LISTING STATUS: Species of special concern
FIRST/LAST RECORDED: 1918/1940
RANGE: Berkeley (Strawberry Canyon), Mt. Diablo, and the East Bay Hills (Orinda Park Pool, Siesta Valley, Calaveras Reservoir)
HABITAT: bare ridge tops, rocky outcrops, thin soils, scattered chaparral, and small annual grasses
FIELD NOTES: the Berkeley kangaroo rat closely resembles the Tulare kangaroo rat (D. h. tularensis), but can be distinguished by generally darker hairs, especially along the back, as well as darker broad stripes along the sides and tail, and smaller patches of lighter hairs on the ears and face; look for k-rat hunter Gary Beeman’s “Wanted!” posters in kiosks surrounding Mount Diablo State Park; if you want to tip off Beeman about a potential k-rat in your neighborhood, you can reach him at (925)284-2602

THE BAY AREA’S HOLY GRAIL—MOUNT DIABLO BUCKWHEAT
The inspiration behind “Presumed Extinct: Lost Species of the Bay Area” was the rediscovery of the Bay Area”s own ivory-billed woodpecker, the Mount Diablo buckwheat. You can learn more about Mount Diablo and its phantom buckwheat through the following features and press releases:

REDISCOVERED “LAZARUS SPECIES” AROUND THE WORLD, AND MORE
When so-called “extinct” species rise from the dead—as we hope our lost Bay Area species are fated to do—they become what are appropriately referred to as “Lazarus species.” You can learn more about such species and how they become extinct, as well as test your knowledge on global extinction—through the links below:
