Black-tie dress code: two new species of the genus Toxomerus (Diptera, Syrphidae)

Toxomerus hauseri Mengual sp. n. and Toxomerus picudus Mengual sp. n. are described from Peru and Ecuador respectively. Toxomerus circumcintus (Enderlein, 1938) is treated as a valid species and not considered synonym of Toxomerus marginatus, and Toxomerus ovatus (Hull, 1942) is considered junior synonym of Toxomerus nitidus (Schiner, 1868). An identification key for the Toxomerus species with dark abdomens is given along with diagnoses for each studied species.     

An unusual new species of the genus Brachypalpus Macquart (Diptera: Syrphidae) from Eastern Asia

Brachypalpus (Brachypalpus) longifacies sp. nov. is described and illustrated from Eastern Asia (Russian Far East and Japan). It differs from other species of the nominative subgenus by several unusual characters, i.e. face in profile weakly convex dorsally and concave ventrally, antennae very elongated, and abdomen with reddish transversal maculae on 2nd tergum (male) or 2nd and 3rd terga (female). A key is given for known species of the subgenus Brachypalpus.LSID: urn:lsid:zoobank.org:pub:634CB6E2-B2C1-40EC-8811-BF3DD4BDE69A

Two new black fly species of Simulium (Simulium) (Diptera: Simuliidae) from South India

Two new black fly species, Simulium (Simulium) pothigaiense sp. n. and Simulium (Simulium) valparaiense sp. n., are described based on females, males, pupae and larvae. Simulium (Simulium) pothigaiense sp. n. is characterized by a claw simple without subbasal tooth and the base of radial vein with hair tuft in the females, maxillary palp with small sensory vesicle in the males, pupal gill with 10 short slender filaments and very short common basal stalk in the pupae and 5 hypostomal bristles per side lying parallel to lateral margin in the larvae. Simulium (Simulium) valparaiense sp. n. is characterized by hind basitarsus 6.6 times as long as its greatest width and claw with small distinct subbasal tooth in the females, gonostyle in medial view 2.3 times longer than coxite in the males, common basal stalk of pupal gill 0.31 times as long as interspiracular trunk, and larval thoracic and abdominal cuticle with pair of dorsolateral protuberances. Taxonomic notes are given to distinguish these two new species from closely related species. www.zoobank.org/urn:lsid:zoobank.org:pub:7285F6BC-607D-4F76-B6EE-9CAC67CDE651

Saproxylic hoverflies benefit by modern forest management (Diptera: Syrphidae)

Saproxylic organisms are regarded as threatened in many European countries. Nevertheless, there have been some signals indicating a recent increase of saproxylic hoverflies in the Netherlands. This paper examines the change in occurrence of saproxylic hoverflies compared to other ecological groups of the same family. The trend analysis is based on the database of an extensive recording programme carried out in the Netherlands. The results show an increase in occupied grid cells for a majority of saproxylic species in relation to other ecological groups. This positive trend occurs among all five ecological subcategories of saproxylic hoverflies recognized in this paper. It is suggested that this increase could be attributed to the changes in the Dutch forests during the past 50 years. Important aspects of these changes are: the increase in forest area (including an increase in area of forest with large and very large trees), the increase in age of forests and the changes in forest management in favour of a more natural approach towards dead and ill trees. In the discussion the possible influence of climate change and the method of trend calculation are discussed.     

Taxonomy of the genus Scatella Robineau-Desvoidy (Diptera: Ephydridae) in Korea

The genus Scatella Robineau‐Desvoidy, including S. callosicosta Bezzi, S. nipponica Miyagi, S. paludum (Meigen) and S. stagnalis (Fallén), is reported for the first time in Korea. A key to the Korean species, and reports of their domestic localities, are given. Some illustrations of male and female genitalic structures are included.     

Taxonomy of the genus Lispe Latreille (Diptera: Muscidae) in Korea

In this paper, a total of four species of the genus Lispe are treated. Of these, L. assimilis Wiedemann and L. litorea Fallén are reported for the first time in Korea. A key to the Korean species, their domestic localities, and some illustrations are given.     

A new species of the genus Malakichthys (Perciformes: Acropomatidae) from Japan

A new acropomatid, Malakichthys barbatus, is described on the basis of 27 specimens (76.3–180.1 mm SL) collected from Suruga Bay to Tosa Bay, along the southern Pacific coast of Japan. The new species is unique in having numerous pairs of spines on the chin (a pair of spines in other congeners). Although the new species resembles M. elegans in having a slender body (the depth less than 35% SL), the former is further distinguishable from the latter in having a slender first proximal radial of the anal fin with no hollow (broad with a cone-shaped hollow in M. elegans), 43–48 lateral line scales (48–51), modally 21 gill rakers on the lower arm (modally 23), and a dark blotch on the opercle (no remarkable blotch).

A new species of the genus Seticornuta Morley (Hymenoptera,Ichneumonidae, Metopiinae) from South Korea

Old World species of the genus Seticornuta Morley are reviewed. Seven species of this genus were recorded worldwide, but only one species, Seticornuta albopilosa (Cameron), was known from the Old World. Here, we report one new species, Seticornuta koreana sp. n., from South Korea, and redescribe the other known Old World species, Seticornuta albopilosa, with photographs.     

A new black fly species of the subgenus Gomphostilbia (Simulium: Simuliidae: Diptera) from India

Simulium (Gomphostilbia) agasthyamalaiense sp. nov. is described based on adults, pupae and mature larvae from a medium-flowing stream of Southern Western Ghats, India. This new species is placed in the Simulium batoense species-group of the subgenus Gomphostilbia Enderlein. This new species is characterized in the female by a scutum with three brownish-black longitudinal vittae and the hind basitarsus 5.7 times as long as wide; in the female by the large facets of upper eye with 20 vertical columns and 19 horizontal rows; in the pupa the respiratory gill with medium-long common basal stalk; and in the larva arrowhead-shaped postgenal cleft. Taxonomic notes are provided for this new species and it can be distinguished from closely related species of S. (G.) peteri. Keys are constructed to distinguish this species from ten species of the batoense species-group recorded in India.www.zoobank.org/urn:lsid:zoobank.org:pub:1D1CFEE5-A762-4F68-9EAE-9E31133146C0
