A new species of the Aenictus ceylonicus group, dirangensis sp. nov., is described and illustrated based on worker caste. The occurs in North-Eastern Himalayas shows morphological similarities with A. yangi Liu, Hita Garcia, Peng, & Economo (2015) wilaiae Jaitrong Yamane (2013). nov. can be separated from both by shape subpetiolar process body sculpture. also resembles khaoyaiensis (2013) b...

The Moscovian of eastern North Greenland has yielded an assemblage dominated by teeth and dermal denticles of chondrichthyans with rarer teeth of actinopterygians. The rather poor preservation of the material precludes precise identification but the following taxa have been recorded: Adamantina foliacea, Bransonella spp., Denaea sp., “Stemmatias” simplex, Lagarodus specularis, Actinopterygii in...

Complex composite odontoma was described as a distinct entity for the first time by Broca in 1866. This lesion takes place because dental components are laid down in a disorganized manner, due to failure of normal morphodifferentiation. The difference between complex and composite odontomas is arbitrary, being based on the preponderance of well-organized denticles as opposed to a preponderance ...

Macrobrachium prabhakarani new species is described from the Vamanapuram River, Kerala, S. India. The species shares certain characters with M. scabriculum and M. madhusoodani, while it differs remarkably from these two species in distinctive diagnostic characters: rostral formula 12–14/1–2 with 5–7 postorbital teeth; carapace smooth with distal end of rostrum directed forwards; chelae with nin...

Two new species of Palapedia Ng, 1993, are described based on material collected from Abu-Musa Island, Persian Gulf during the present study, from Bahrain by the 1937/38 Danish Expedition, and from the Saudi Arabian coast of the Persian Gulf by Michael Apel in 1992-1995. Palapedia persica n. sp. is distinguishable from its congeners by having distinctly large denticles on the upper margin of th...

A new species of Numbakulla Guţu & Heard, 2002 (Tanaidacea) is described from Heron Island (southern Great Barrier Reef, Queensland) collected during the Census of Coral Reefs Ecosystem (CReefs) program. The new species is the third member of the family and can be recognized by the combination of characters as: length/width ratio of the body, which is 6:7, pereonite 4 longer than the rest, the ...

A new species, Chaeriluspseudoconchiformus sp. n., is described from Xizang, China. The present new species is distinguished from its congeners by a body length of 32-40 mm, carapace with the anterior margin straight, chela with length/width ratio average of 3.3 in males (3.2-3.4, two adults), and 2.5 in females (2.3-2.6, nine adults), eight or nine (eight usually) rows of denticles on fixed an...

PLoS Biology | http://biology.plosjournals.org The Wnt/Wingless (Wg) pathway is an evolutionarily conserved signaling pathway that plays important roles in normal development and cancer, from worms and flies to mice and humans. Two papers, identifying the first components of this pathway, initiated the active research field of Wnt/Wg signal transduction and profoundly influenced my scientific c...

Pterygodermatites (Paucipectines) baiomydis n. sp., an intestinal parasite of the northern pygmy mouse, Baiomys taylori (Cricetidae), collected in La Yerbabuena, Colima, Mexico, is described herein. Specimens were studied using light and scanning electronic microscopy. This is the 19th species of the subgenus Paucipectines described worldwide and the fourth collected in Mexico. It is differenti...
