Two New Species

Two new species, Laonice costaricensis sp. nov. and L. rasmusseni sp. nov., belonging to the subgenus Norgensia Sikorski et al., 2017 were found in material from the Pacific collected from Coco Island off the coast of Costa Rica and from the Atlantic collected from Sapelo Island off the coast of Georgia (USA), respectively. Laonice cosaricensis is very close morphologically to L. lemniscata but without transdorsal membranes and having as usual capillaries in several anterior parapodia arranged in three vertical rows. Laonice rasmunsseni has genital pouches starting much anteriorly than in all known species from this subgenus. An identification key for the species belonging to this subgenus is given.

Phyletic Line

The milliped genus Amplaria Chamberlin 1941 was synonymized with Striaria Bollman 1888 by Hoffman (1980). Examination of a much wider range of materials of nominal Striaria species both from eastern North America and the Pacific coastal states shows that some species occurring from California to Washington (state) represent a distinct phyletic line, for which Amplaria Chamberlin 1941 is the oldest available generic name. Speostriaria Causey 1960 is a synonym of Amplaria. Amplaria muiri n. sp. and A. adamsi n. sp. are two new, recently discovered species from caves in Sequoia and Kings Canyon National Parks, California. Illustrations are provided of a specimen that may represent the type species, Amplaria eutypa (Chamberlin) 1953.

Based on material from aquatic habitats in the northern Chihuahuan Desert and a literature review, we present an account on the occurrence of genus Rhinoglena in North America. Two new species are described, and the presence of Rhinoglena frontalis in the USA is confirmed. Of the two new species, R. texana n. sp. is a close relative of R. frontalis, whereas R. ovigera n. sp. is unique by being oviparous, in contrast to all other Rhinoglena which are viviparous. This prompts a revision of the generic diagnosis of Rhinoglena to accommodate the new species. An identification key to the known species of the genus is provided.

Two New Species

The genus Lobelia is cosmopolitan and comprises 423 species in 18 sections. Lobelia sect. Stenotium is the most diverse group with 153 species, has a wide distribution in continental North America and is segregated into two subgroups based on the presence of spurred flowers. There are 16 spurred Lobelia species that occur in streamside or seep areas, throughout pine and oak mixed forests from USA to Costa Rica, but they are frequent along the Pacific slopes of the Sierra Madre Occidental (SMO), Mexico, where 10 species grow. In this paper we present a synopsis of the spurred species of Lobelia in the SMO and propose two new taxa. First, Lobelia rzedowskii is morphologically similar to L. ayersiae, L. cordifolia and L. endlichii but differs by its rosulate leaves, blades 0.5–1.5 × 0.4–1 cm, subsessile, racemose to paniculate inflorescences, with (4–)10–35(–191) flowers, flowers 4–6 mm long including hypanthium, spur 0.5–1 × 0.5–0.8 mm, with the lower two calyx lobes positioned at the middle portion of the spur, white corolla with a yellow spot above lobe sinuses on the throat and staminal tube 1.3–2.5 mm long. Second, Lobelia saturnini is morphologically similar to L. knoblochii, L. macrocentron, L. mcvaughii and L. villaregalis, but differs from them by leaves (2–)4–14(–17) mm long, petioles 2–6(–17) mm long, solitary flowers, flowers 12–16 mm long including hypanthium, hypanthium 1.2–2.5 mm long, spur 2–3 mm long, pedicels (1.3–)2–9(–12) cm long and anthers 1–2.2 mm long. We include an identification key for spurred species of Lobelia in the SMO, photographs, distribution notes with a map, and illustrations.

Pacific Species

Two new species of the hexactinellid family Tretodictyidae, both collected by submersible, have been discovered off the coasts of North America. The Pacific species, Tretodictyum montereyensis n. sp., has an unusual skeleton with a fused cortex added over the usual tretodictyid system of ridges and grooves on the dermal surface. The Atlantic species, Hexactinella carolinensis n. sp., is unusual among its congeners in having swollen nodes on the dermal skeleton. Diagnoses of both genera have been modified to accommodate the new findings. The fine diactins of both species are found to have shallow brackets and short barbs, confirming their uncinate nature. Addition of these two species raises the number of known North American tretodictyids from one to three.

Two New Species

Two new species of the actiniid genus Epiactis, Epiactis lisbethae and Epiactis fernaldi, are described from the intertidal zone of the San Juan Islands, Washington, U.S.A. The sea anemone genus Cnidopus is synonymized with Epiactis, and its type species, C. ritteri, is restored to the genus in which it was originally described. Thus, four species of Epiactis are known on the Pacific coast of North America: external brooders E. prolifera (type species of the genus) and E. lisbethae, which differ in sexuality and brooding periodicity; and internal brooders E. ritteri and E. fernaldi, which differ in cnidae, sexuality, and histology. These bring the number of nominal species in the genus Epiactis to 19.

A New Species

Euschistus Dallas is comprised of 66 species in three subgenera. Species of the nominate subgenus occur mainly in Central and North America. Some groups of species have been proposed to Euschistus (Euschistus) based on general external and male genitalic morphologies. Here, we review the sulcacitus group providing illustrations and descriptions of the internal and external genitalia of both sexes, illustrating females for the first time. A new species, Euschistus (Euschistus) tacitus sp. nov. Bianchi & Grazia, from Mexico and Costa Rica is described. We also provide an identification key to species of the group.
