Three New Species

We describe three new species of Pristimantis from the upper montane forests and high Andean grasslands of the Pui Pui Protected Forest and its close surroundings (Región Junín, central Peru) and compare them morphologically and genetically with other taxonomically and biogeographically relevant species of Pristimantis. All three new species have the skin on dorsum shagreen with scattered tubercles, discontinuous dorsolateral folds, tuberculate flanks, and the skin on venter areolate. Pristimantis bounides sp. nov. is known from two localities outside the Pui Pui Protected Forest in upper montane forests between 3350 and 3463 m a.s.l. and is characterized by a snout–vent length of 18.2–21.0 mm in males (n = 3), and 21.6–24.4 mm in females (n = 4), by having a tympanum, males with vocal slits, and discs of digits slightly expanded with circumferential grooves. In life, dorsal and lateral ground coloration is pale grayish brown, orange brown, yellowish brown or reddish brown with dark grayish-brown marmorations, and a pale gray, pale greenish gray or creamish white venter with or without dark gray mottling. Pristimantis humboldti sp. nov. is known from one locality inside the Pui Pui Protected Forest, in upper montane forest at 3318 m a.s.l., and is characterized by a snout–vent length of 17.2–20.6 mm in males (n = 3), and 19.7–25.7 mm in females (n = 6), by having a tympanum, males with vocal slits, and discs of digits expanded with circumferential grooves. In life, dorsal and lateral ground coloration is orange brown with brownish-olive blotches, orange brown with grayish-brown blotches and flecks, reddish brown with grayish-brown blotches or grayish brown with orange brown blotches; throat, chest, belly, anterior and ventral surfaces of thighs, tibia, and axilla are dark gray and pale gray mottled with white and pale gray spots of different sizes and density. Pristimantis puipui sp. nov. is known from one locality inside the Pui Pui Protected Forest, in the puna at 3890 m a.s.l., and is characterized by a snout–vent length of 16.1–17.1 mm in males (n = 3), and 20.6–22.4 mm in females (n = 4), by lacking a tympanum, lacking males with vocal slits, and tips of digits narrow without circumferential grooves. In life, dorsal and lateral ground coloration is pale orange brown, reddish brown or grayish brown with or without grayish-brown mottling, and the venter is pale cream and pale gray mottled. A molecular phylogenetic analysis based on mitochondrial and nuclear DNA sequences inferred that the three new species belong to the Pristimantis danae species Group distributed in the montane forests and high Andean grasslands of central Peru, including P. albertus, P. aniptopalmatus, P. ornatus, and P. stictogaster. With the three new species, 133 species of Pristimantis are currently known from Peru, eight of which inhabit the puna.

Sequence Similarity Analysis

ABSTRACT Molecular phylogenetic analysis of a naturally occurring microbial community in a deep-subsurface geothermal environment indicated that the phylogenetic diversity of the microbial population in the environment was extremely limited and that only hyperthermophilic archaeal members closely related to Pyrobaculum were present. All archaeal ribosomal DNA sequences contained intron-like sequences, some of which had open reading frames with repeated homing-endonuclease motifs. The sequence similarity analysis and the phylogenetic analysis of these homing endonucleases suggested the possible phylogenetic relationship among archaeal rRNA-encoded homing endonucleases.

A New Species

Ottelia guanyangensis (Hydrocharitaceae), a new species from southwestern China, is described and illustrated. This aquatic plant is a perennial, submersed herb with bisexual flowers and a hexagonal-cylindric fruit. It is related to O. acuminata var. songmingensis and O. balansae but differs from these two taxa by its bisexual flowers, spathe with 2–5 flowers, trinerved leaf with obvious cross veins, and a winged, hexagonal-cylindric fruit. Molecular phylogenetic analysis based on nuclear DNA internal transcribed spacer (ITS) sequences and three chloroplast DNA sequences (rbcL, trnK5’ intron and trnS-trnG) resolves O. guanyangensis as a distinct clade, which further justifies its recognition as a new species.

Boletus peckii, B. pulchriceps and B. roseopurpureus, which were originally described from North America, are characterized by a yellow tube layer that often bruises blue, a yellow reticulated stipe especially at the apex, firm yellow-tinged flesh that often turns blue when exposed, smooth spores and an interwoven trichodermic pileipellis. The phylogenetic positions of the three species are inferred by molecular phylogenetic analysis based on DNA sequences of four gene markers (ITS, nrLSU, tef1-α and rpb1). Both morphological features and molecular phylogenetic evidence indicate that these three boletes belong to Butyriboletus, and thus, should be transferred to the genus.

A New Species

Phyllanthus kaweesakii Pornp., Chantar. & J.Parn. sp. nov. is newly described from the limestone mountain ridges in the northeast of Thailand. Comparison of morphology, anatomy, pollen morphology, and DNA sequences of this species with the most similar existing species P. mirabilis Müll.Arg. was undertaken. The results indicated that the two taxa are different in morphology, especially habit, stem base, and inflorescence, but that their pollen morphology and anatomy are similar. The molecular phylogenetic analysis, based on sequences of the plastid matK and nuclear ribosomal ITS regions, supported separation of the two taxa. This new species is described and illustrated, and its conservation status is discussed.
