A New Species

In southern Chile two species of Ceratocystis were found to be responsible for most of the initial blue stain in logs and lumber of Auraucaria araucana (Mol.) K. Koch. The more important Ceratocystis auraucariae Butin sp. nov. and its Verticicladiella conidial state are described and illustrated. This species is characterized by a fast-growing brown mat of mycelium, small, long-necked perithecia, and cylindrical, slightly curved ascospores. Ceratocystis moniliformis (Hedge.) C. Moreau, Melanconiopsis elzoi Speg., Epicoccum nigrum Link, and Cladosporium sp. were found as associated fungi.

A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

A New Species

Triangularia backusii n. sp. was isolated from a soil sample collected in Ohio, U.S.A., and was subjected to alcohol treatment. Triangularia backusii is characterized by oval to pyriform perithecia, elongate-clavate asci, and obovoid ascospores with hyaline, gelatinous appendages. The ascospores are two-celled with a transverse septum; the upper cell is obovoid with a truncate base and brownish black to black and the lower cell is triangular and pale brown to brown. The conidial state is assignable to the genus Phialophora. The new species differs from other known Triangularia species in having the largest ascospores.

A New Species

Sternaspis chilensis n. sp. is described based on specimens collected in channels and fjords of southern Chile and previously identified as Sternaspis scutata (Ranzani, 1817), originally described from the Meditarrean Sea. Sternaspis chilensis n. sp. is described based on the features of the shield with anterior margins rounded and anterior depression shallow; marginal shield chaetal fascicles arranged with an inverted C-shaped pattern; and distribution of the integument papillae. Sternaspis chilensis is widely distributed in the Magellan Province from Estero Reloncaví (41°32’54”S, 72°19’48”W) to Strait of Magellan (53°34’S, 70°04’W), between 50 and 515 m depth.

A New Species

A new species of amphipod of the family Ischyroceridae is described. Isaeopsis chiloensis n. sp. was discovered in association with the cancrid species Metacarcinus edwardsii and Romaleon setosum, in the inner sea around Chiloé Island, in Southern Chile. This represents the second species of the genus Isaeopsis, a group formerly known only from South African waters.                The new species is characterized principally by the structure of the gnathopods, the propodus of pereopods 3–7 and the ornamentation of the outer ramus of uropod 3. The male gnathopod 2 has a prominent thumb in the posteroproximal margin of the propodus and the pereopods 3–7 are subchelate with the palm armed by a row of at least five strong setae. In addition, the apex of the outer ramus of uropod 3 bears a comb with more than thirty fine teeth. Isaeopsis chiloensis n. sp. is completely described and a series of illustrations is provided.

A New Species

A new species of Arachniotus is figured and described. This species, A. striatosporus, is characterized by having fusiform ascospores which appear striate in surface view because of the presence of five to nine more or less longitudinal ridges. The ascospores appear stellate in cross section. The species has a conidial state belonging to the form genus Oidiodendron.
