New species of Echinoderes (Kinorhyncha: Cyclorhagida) from Spitsbergen,with additional information about known Arctic species

The kinorhynch fauna in two Arctic fjords at Spitsbergen was explored and eight species of Echinoderes were recorded, of which three are new to science and described herein. Echinoderes daenerysae sp. nov. is recognized by middorsal spines on segments 6 and 8 only, lateroventral spines on segments 6–9, laterodorsal and ventrolateral tubes on segment 2, lateroventral tubes on segment 5, lateral accessory tubes on segment 8, laterodorsal tubes on segment 9 and small laterodorsal tubes on segment 10. Echinoderes rhaegali sp. nov. has middorsal spines on segments 4, 6 and 8, lateroventral spines on segments 6–9, sublateral and ventrolateral tubes on segment 2, lateroventral tubes on segment 5, lateral accessory tubes on segment 8 and laterodorsal tubes on segment 10 in males. Echinoderes drogoni sp. nov. has middorsal spines on segments 4–8, lateroventral spines on segments 6–9, lateral accessory tubes on segment 5, glandular cell outlets type 2 in subdorsal, laterodorsal, sublateral and ventromedial positions on segments 2, in midlateral positions on segment 5, in sublateral positions on segment 8 and in subdorsal positions on segment 10; segment 11 has divided tergal plates. Moreover, types of other Arctic Echinoderes, including E. angustus, E. aquilonius, E. eximus, E. peterseni, E. svetlanae and E. tubilak, were re-examined and new information on glandular cell outlets type 2 is provided. Our results suggest that Arctic Echinoderes species have a circum-Artic distribution. Morphological analysis indicates that the occurrence of tubes may show intraspecific variation.

Pollen‐feeding in hover‐flies (Diptera: Syrphidae)

Analyses of the pollen contents of the crop and intestine of 11 species of New Zealand Syrphidae . showed that small, sparsely haired hover‐flies with unbranched hairs, short, simple bristles, and a short proboscis had ingested at least 99% anemophilous pollens, and that larger, more hairy hover‐flies with pollen‐collecting hairs, long, spirally grooved bristles, and elongate mouthparts had ingested pollens almost exclusively from nectar‐bearing flowers. Pollen‐feeding behaviour was studied in one hairy species, the drone‐fly Eristalis tenax, and in one sparsely‐haired species, Melanostoma fasciatum. Using granulated charcoal as a substitute for pollen, it was found that in E. tenax particles trapped among the body hairs are combed off by the front and hind tibiae and transferred to pollen‐retaining bristles on the front and hind tarsi respectively. Particles retained among the front tarsal bristles are ingested directly from the bristles. Those retained by the hind tarsi are transferred in flight by leg‐scraping movements to the front tarsi, from which they are subsequently eaten. E. tenax also eats pollen directly from anthers. In M. fasciatum apparently all the pollen ingested is taken directly from anther lobes or stigmas. The few pollen grains that adhere to the body of this species are combed off by the front and hind tibiae and transferred to the front and hind tarsi, but are not retained there because the bristles are short and simple. The mouthparts, hairs, and bristles of E. tenax and M. fasciatum are illustrated. Drawings of leg movements associated with pollen collection and ingestion, and photographs showing leg scraping in E. tenax are included. Morphological similarities between drone‐flies and honey‐bees, previously regarded as the result of mimicry, can be explained by convergent evolution in response to similar food‐gathering behaviour. Probably the majority of Syrphidae, and also the related Acroceridae, collect pollen by means of branched or curly‐tipped hairs.     

Two New species of the dipteran genus Dolichopus Latreille (Diptera,Dolichopodidae) from Siberia and Mongolia

Two new species of the genus Dolichopus Latreille (Diptera, Dolichopodidae) are described from Mongolia and Siberia. Dolichopus tschernovi Negrobov, Barkalov et Selivanova, sp. n. is similar to Dolichopus bayaticus Negrobov, 1976, but differs in the presence of one seta on the hind metatarsus, the shorter 3rd antennal segment, and in the structure of the hypopygium. Dolichopus lenensis Negrobov, Barkalov et Selivanova, sp. n. resembles Dolichopus setitarsis Negrobov et Barkalov, 1977, but differs in the slightly widened 2nd–4th segments of the middle tarsus, in the presence of one seta on the hind metatarsus, and in the structure of the hypopygium. Drawings of the antennae, tarsi, and hypopygium of the new species are given. The holotypes of the new species are deposited in the Zoological Institute, the Russian Academy of Sciences (St. Petersburg).     

A new species of the genus <Emphasis Type="Italic">Coccophagus</Emphasis> Westwood (Hymenoptera,Chalcidoidea, Aphelinidae) inhabiting ants’ nests (Hymenoptera,Formicidae) in Malaysia

Coccophagus brachypterus sp. n. is described from Malaysia. The new species differs from the closely related C. silvestrii Compere in the black hind femur and blackish largest part of hind tibia. The new species is also characterized by shortened fore wings with the apices not reaching the abdominal apex.     

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.     

Hind foot drumming: Morphofunctional analysis of the hind limb osteology in three species of African mole-rats (Bathyergidae)

Hind foot drumming is a form of seismic signaling that plays a vital role in the communication of several Bathyergidae species. Hind foot drumming is initiated by the rapid movement of the whole hind limb by flexion and extension of the hip and knee. This study aimed to determine if morphological adaptations of the hind limb osteology were measurable using established morphometric analyses in two drumming (Bathyergus suillus and Georychus capensis) and one non-drumming (Cryptomys hottentotus natalensis) African mole-rat species. Forty-three linear measurements of the hind limb were taken in 48 limbs (n = 16 limbs per species) and 32 indices were calculated. Mixed model analysis of variance was used to compare the three species and sexes within a species. Thirteen indices had significant differences between species. Eleven indices had significant differences between sexes within a species. Significant differences between the drumming (B. suillus and G. capensis) and the non-drumming species were observed in three indices. The femoral greater trochanter was relatively shorter in the drumming species compared to the non-drumming species, which is proposed to allow for increased hip joint mobility, thereby permitting drummers to move their limbs at the rapid speed required to generate seismic signals. Furthermore, the small in-lever (shorter greater trochanter) may increase the velocity of limb motion. The robust tibias in the drumming species, as indicated by the tibial robustness index, are likely to counter the additional biomechanical load caused by the muscles involved in hind foot drumming. The relatively small hind feet seen in the drumming species allows for reduced limb weight needed for the rapid extension and flexion motion required during hind foot drumming. The significant differences reflected in the hind limb osteological indices between B. suillus and G. capensis and the non-drumming species are indicative of adaptations for hind foot drumming.
