Cambarus (Puncticambarus) theepiensis is a stream-dwelling crayfish that appears to be endemic to the junction of the Cumberland Mountains with the Appalachian Plateau in West Virginia and Kentucky. Within this region, it is prevalent in the Guyandotte and Twelvepole basins of West Virginia, the Little Sandy River and Levisa Fork basins of Kentucky, and tributaries of the Big Sandy River shared...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

Three atyid shrimp species of the genus Caridina Milne Edwards, 1837, Caridina boehmei n. sp., C. laroeha and C. butonensis n. sp., are described from the Indonesian islands Sulawesi and Buton. Caridina boehinei n. sp. differs from its apparently next congener C. sulawesi Cai & Ng, 2009 by the shape of the spinulation of the male sexual appendages. Caridina laroeha resembles C. mahalona and C. ...

A new weevil, Pheudepunctatus gen. et sp. n., of the tribe Dryotribini in Cossoninae, is described from Guangdong Province, South China. It differs from the related genera Dryotribus Horn and Microtribodes Morimoto in having antennae with seven articles and a distinct scutellum, and from Ochronanus Pascoe and Stenomimus Wollaston in having long antennae, a rostrum with a medio-longitudinal furr...

Bite force is one of the most utilized performance measures due to its association with feeding and consequently fitness. Due to their large size and the concomitant increase in the adductor muscles it is expected that apex predators may rely on high biting performance allowing for increased dietary breadth. Billfish are apex marine predators characterized by the extreme elongation of the upper...

Scanning (SEM) and transmission (TEM) electron microscopy were used to elucidate the morphology of the rostrum, as well as the mandibular and maxillary stylets of the psyllid Diaphorina citri, vector of phloem-inhabiting bacteria associated with citrus huanglongbing (HLB) disease. D. citri has a cone-shaped rostrum that extends behind the pair of prothoracic coxae. The stylet bundle comprises a...

To understand the effects of anthropogenic disturbance on nutritional health animals, it is important to measure and morphometrics, allometrics, body condition species. We examined shape, allometric relationships, short-finned pilot whales (Globicephala macrorhynchus) in three locations across North Atlantic. Using unmanned aerial vehicles, length (BL) width (along axis) were measured from phot...

Synommatus leleji sp. n. is described and illustrated from the Philippines (Mindanao Island). The new species differs other of genus in suboval elytra with rounded sides, rugose-punctate pronotum, rostrum subequal to pronotum length. A key distribution map for are given. It first record Philippines.

Most caridean decapods have compound eyes of the reflecting superposition kind, and additionally some possess an accessory eye-like organ of unknown function, also referred to as the nebenauge. We examined 308 caridean genera to assess the general morphology of the eye, rostrum length, eye diameter and the presence or absence and, when present, the diameter of the nebenauge. We have attempted t...
