Discoveries of the week #37

A new species, Cherax (Astaconephrops) pulcher sp. n., from Hoa Creek, close to the village Teminabuan in the southern-central part of the Kepala Burung (Vogelkop) Peninsula, West Papua, Indonesia, is described, figured and compared with the morphologically closest species, Cherax boesemani Lukhaup & Pekny, 2008.

New species of crayfish with a species named derived from the Latin word “pulcher” meaning beautiful, alluding to the colorful appearance of the species.

Previous research of Bornean Micronectidae Jaczewski, 1924 (pygmy water boatmen) is summarized based on the data from the literature and recent work. All the Bornean micronectids belong to the genus Micronecta Kirkaldy, 1897. Descriptions or redescriptions and a key to the eight species, which have so far been found in Borneo are presented, namely M. decorata Lundblad, 1933, M. ludibunda Breddin, 1905, M. liewi sp. n., M. lakimi sp. n., M. lumutensis Chen, Nieser & Lansbury, 2008, M. skutalis Nieser & Chen, 1999, M. kymatista Nieser & Chen, 1999) and M. quadristrigata Breddin, 1905. The synonyms are indicated under each species. To facilitate identification, illustrations and habitus photos are provided. The faunistic components of Micronectidae in Borneo are discussed from a zoogeographic point of view.

Two new pygmy water boatmen species from Borneo. One species was named in honor of Dr. Thor Seng Liew (NBC Naturalis and Sabah University, Malaysia) and the second after Dr. Maklarin Lakim who help service organizing the expedition in which the new species were discovered.

The Russet Bush Warbler Locustella (previously Bradypterus) mandelli complex occurs in mountains in the eastern Himalayas, southern China, Vietnam, the Philippines, and Indonesia. The taxonomy has been debated, with one (L. seebohmi) to four (L. seebohmi, L. mandelli, L. montis and L. timorensis) species having been recognised. We used an integrative approach, incorporating analyses of morphology, vocalizations and a molecular marker, to re-evaluate species limits in the L. mandelli complex. We found that central Chinese L. mandelli differed from those from India through northern Southeast Asia to southeast China in plumage, morphometrics and song. All were easily classified by song, and (wing + culmen)/tail ratio overlapped only marginally. Both groups were reciprocally monophyletic in a mitochondrial cytochrome b (cytb) gene tree, with a mean divergence of 1.0 ± 0.2%. They were sympatric and mostly altitudinally segregated in the breeding season in southern Sichuan province. We found that the Mt Victoria (western Myanmar) population differed vocally from other L. mandelli, but no specimens are available. Taiwan Bush Warbler L. alishanensis was sister to the L. mandelli complex, with the most divergent song. Plumage, vocal and cytb evidence supported the distinctness of the south Vietnamese L. mandelli idonea. The Timor Bush Warbler L. timorensis, Javan Bush Warbler L. montis and Benguet Bush Warbler L. seebohmi differed distinctly in plumage, but among-population song variation in L. montis exceeded the differences between some populations of these taxa, and mean pairwise cytb divergences were only 0.5–0.9%. We also found that some L. montis populations differed morphologically.

This new bird, the Sichuan bush warbler, resides in five mountainous provinces in central China.It was named in honor of the late Cheng Tso-hsin, China's greatest ornithologist. Cheng, founder of the Peking Natural History Museum.

The taxonomy of Chamaedrilus glandulosus (Michaelsen, 1888) s. l., most commonly known previously as Cognettia glandulosa, is revised. A recent molecular systematic study has shown that this taxon harbours two cryptic, but genetically well separated lineages, each warranting species status. In this study these two lineages are scrutinized morphologically, on the basis of Michaelsen’s type material as well as newly collected specimens from Central and Northern Europe. Chamaedrilus glandulosus s. s. is redescribed and Ch. varisetosus sp. n. is recognized as new to science. The two species are morphologically very similar, differing mainly in size, but seem to prefer different habitats, with Ch. glandulosus being a larger aquatic species, and Ch. varisetosus being smaller and mainly found in moist to wet soil.

A new enchytraeid species named after the variation in numbers of chaetae in the lateral preclitellar bundles. 

Three new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) are described from Colombia; namely R. diegoi sp. n. (Forceps Group) and R. guacharoensis sp. n. (Marginipennis Group) from Parque Nacional Natural Cueva de los Guacharos in Huila, and R. gorgonaensis sp. n. (Crassicornis Group) from Parque Nacional Natural Gorgona in Cauca. Ripipteryx diegoi sp. n. is characterized by the antennae black with white spots on flagellomeres 3–7, male subgenital plate with median ridge forming a bilobed setose process, epiproct produced laterally near its base and phallic complex with virga thickened distally and not reaching beyond the membrane. Ripipteryx guacharoensis sp. n. is characterized by the antennae thick with white spots present dorsally on flagellomeres 1–4 and 8, epiproct narrow and triangular, uncus reduced and lacking a distal hook, phallic complex with a concave ventral plate and a dorsal elevation in the middle extended to the virga, and the virga itself with two small projections basally. Ripipteryx gorgonaensis sp. n. is characterized by the epiproct with a lateral notch, antennae with a white dorsal spot on flagellomere 1 and flagellomeres 4–7 entirely white. The antennal color pattern of R. gorgonaensis sp. n. strongly resembles that of R. atra but differs from the latter in the absence of any significant morphological modification of the flagellomeres.

Three new mudcricket species, one named after the father of the first author, and the two after their respective type localities.
