Upper Paleocene

Three new species of the shallow-marine, warm-water bivalve Plicatula are reported from the upper Paleocene Santa Susana Formation of southern California. Plicatula simiensis new species is from the middle part of the formation on the south side of Simi Valley and occurs as a displaced specimen in deep-marine turbidites. Plicatula lapidicina new species and P. trailerensis new species are both from coralline-algal-rich muddy siltstone just beneath a nearshore, coralline-algal limestone interval in the upper part of the formation in the Santa Ynez Canyon area, east-central Santa Monica Mountains. These three new species represent the first late Paleocene records of genus Plicatula on the west coast of North America and the first Paleocene records of this genus in southern California.

Iodine Reaction

AbstractA new species, Placocarpus americanus, is described from the Santa Monica Mountains in Southern California. It is a juvenile parasite on Protoparmeliopsis muralis and differs from Placocarpus schaereri in having smaller non-halonate ascospores, a negative iodine reaction of the medulla, lack of inspersion of the medulla with small crystals, and having a thallus of dispersed areoles.

Three New Species

The Cretaceous and early Cenozoic species of the shallow-marine, warm-water bivalve Plicatula from California (United States) and Baja California (Mexico) are reviewed, and three new species are named. All of these species are representatives of Plicatula and not of the closely related taxon Harpax, which is associated with high-latitude and cool-water regions. The earliestknown Cretaceous species of Plicatula from the study area is P. variata Gabb, 1864, from Lower Cretaceous (Hauterivian Stage) strata in northern California, and our studies show it to be conspecific with Plicatula onoensis Anderson, 1958.Plicatula allisoni new species is from Lower Cretaceous (Albian Stage) strata in Baja California, Mexico. Plicatula modjeskaensis new species is from Upper Cretaceous (Turonian Stage) strata in the Santa Ana Mountains, southern California. A possible new species from the same strata is also mentioned. A poorly preserved specimen of Plicatula? sp. is known from Upper Cretaceous (upper Campanian to lower Maastrichtian) strata in northern California.The only Paleocene species of Plicatula from the study area is P. ostreiformis Stanton, 1896, from lower Paleocene strata of Lake County, northern California, and our studies show it to be conspecific with Ostrea buwaldana Dickerson, 1914. The only previously described Eocene species of Plicatula from the study area is P. juncalensis Squires, 1987, from lower middle Eocene (“Capay Stage”) strata of Los Angeles County, southern California. Plicatula surensis new species is from middle lower Eocene (“Capay Stage”) strata in Baja California Sur, Mexico. In addition, there is a Plicatula? sp. from Eocene strata of Baja California Sur, Mexico.Although Plicatula is of uncommon occurrence north of Baja California, its thermophilic trait makes it useful in recognizing periods of warm climate.

Three New Species

Three new species of the gekkonid genus Cyrtodactylus are described from Peninsular Malaysia; C. jarakensis sp. nov. from Pulau Jarak off the west coast of Perak, C. batucolus sp. nov. from Pulau Besar of the Water Islands Archipelago off the west coast of Melaka, and C. pantiensis sp. nov. from the Gunung Panti Forest Reserve, Johor. All are distinguishable from other Sunda Shelf species of Cyrtodactylus in having unique combinations of morphological and color pattern characteristics. The continued high potential for finding additional new species in unexplored regions of southern Peninsular Malaysia and its associated archipelagos is further supported with these findings.

First Time

A review of the West African “snail-killing flies” or “marsh flies” (Sciomyzidae) shows that the fauna is not as dominated by the generally aquatic, predaceous genus Sepedon as was previously considered. Twenty species in seven genera, including three new species, Colobaea occidentalis, Pteromicra zariae and Sepedonella castanea are recorded. The Holarctic-Oriental genera Colobaea and Pteromicra are documented from Africa south of the Sahara for the first time. Biogeographical analyses based on the discovery of “Palaearctic” genera of Diptera south of the Sahara, faunal connections, and dispersal routes are presented. A key for identification and illustrations of diagnostic characters for some species are included.
