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...

I revise the Australian-New Guinean ghost moth genus Elhamma. Two recent synonymies are assessed, and two new species from New Guinea, E. grehani sp. nov. and E. viettei sp. nov. are described. I provide an updated diagnosis for the genus and conclude that the presence of only 2 M-veins in the hind wing in both sexes (when females are known) and a strongly cup-shape juxta in the male genitalia ...

The preimaginal stages including egg, mature larva and pupa of Pseudaspidapion botanicum Alonso-Zarazaga & Wang, 2011 were described and figured, diagnostic characters of larva and pupa were discussed, and corresponding biological information was supplied. The nomenclature of frontal setae in the larva compared with curculionid weevils, the absence of the hypopharyngeal bracon in the larva, and...

Abstract Diagnostic characters from 227 pterosaur species were listed, separated into cranial or post-cranial elements and counted. From 21 23 elements, most diagnostic related to phalanges (15%) rostrum. Post-cranial comprise 44.23%, 55.77% of all used in diagnoses. The highest correlation between features occurs the coracoid scapula. 25.11% 28.63% sampled taxa diagnosed with 3-4 5-6 character...

We describe 5 specimens of Choerodon margaritiferus Fowler and Bean, 1928 (94.5-107.0 mm standard length, 1 male and 4 females) collected near Okinawa Island, southern Japan. This is the northernmost record of this species and the first record of it in Japanese waters; until now, C. margaritiferus was recorded only from the western central Pacific. This species was originally described on the b...

A polytomous identification key for 24 species of Radopholus was constructed using the computer software packages EXCEL 5.0., spreadsheets and BIKEY 7 (©Lobanov & Dianov, 1994). Specimen identification is based on the principle that the initial set of taxa can be investigated interactively and reduced by different filters (i.e. character states) in several steps of identification. Quantitative ...

A new family, genus and species of cubozoan box jellyfish belonging to the order Chirodropida is reported from the eastern Japan. Meteoronakishinouyei gen. et sp. n. possesses the following unique morphological characters with respect to other known species in the Chirodropida: having one tentacle per scalpel-like unbranched pedalium and slightly raised unbranched gastric saccules. A comparativ...
