New genus and new species of leaf-mimic pygmy grasshoppers from China (Orthoptera: Tetrigidae: Cladonotinae)

Many species of pygmy grasshoppers (Tetrigidae) exhibit leaf-like appearance, leaf-mimic pygmy grasshoppers mainly characterized by having high pronotal crest (= elevated median carina). A new genus of leaf-mimic Cladonotinae, Deltonotusoides gen. nov., and a new species, Deltonotusoides strictivertex sp. nov. are described from Motuo, Xizang, China.

Three new species of the genus Bodotria (Crustacea: Cumacea: Bodotriidae) from the Yellow Sea in Korea

Three new species of Cumacea belonging to the genus Bodotria were collected from the Yellow Sea in Korea. Among them, Bodotria (Bodotria) hwanghaensis sp. nov. and Bodotria (Bodotria) pseudomaculosa sp. nov. share the dorso-lateral carina on the carapace and uniarticulated uropod endopod with other Korean Bodotria species. In contrast, the last one, Bodotria (Atlantobodotria) incarinata sp. nov. lacks the dorso-lateral carina on the carapace and has a biarticulated uropod endopod. The new species B. (A.) incarinata sp. nov. can be distinguished from all other Bodotria species by the combination of carapace without dorso-lateral carina or ridge, dorso-median carina marked over whole length of carapace, antero-lateral corner of carapace rounded, antennal notch shallow, maxilliped 3 merus and carpus dilated, pereopod 1 carpus not dilated, and pereopod 2 basis with plumose seta. The new species B. (B.) hwanghaensis sp. nov. can be distinguished from all other Bodotria species by the combination of carapace almost ovoid in dorsal view, carapace lower edge of mid-lateral depression forming a faint ridge, pereopod 1 carpus not dilated, and pereopod 2 basis without plumose seta. The new species B. (B.) pseudomaculosa sp. nov. can be distinguished from all other Bodotria species by the combination of carapace surface covered with coarse squamosa-reticulate patterning formed by large, shallow pits, carapace lower edge of mid-lateral depression forming an angular ridge, pereopod 1 carpus little dilated, and pereopod 2 basis with plumose seta. We described with full illustrations, including mouthparts for the three new species. Also, a key to the Korean Bodotria species is provided.

A remarkable new species of the rove beetle genus Anthobium Leach, 1819 from Eocene Baltic amber (Coleoptera, Staphylinidae, Omaliinae)

An unusual new omaliine species, Anthobium alekseevisp. nov., is described and illustrated from Eocene Baltic amber, tentatively placed in the megadiverse genus Anthobium Leach, 1819. A new monotypic species-group is established. The new species can easily be distinguished from other species of the genus by the larger body, shape of the subrectangular pronotum, and the presence of a median carina on the prosternum and large, subtriangular tooth on the inner side of each mesotibia, likely exhibiting a peculiar sexual dimorphism in the male. Based on the study of the specimen with support of microtomographic images, a brief comparative analysis of a new species with described extant species of Anthobium is provided.

Comparative analysis of mitogenomes among three species of Haplotropidini grasshoppers and a new species of the genus Sulcotropis (Orthoptera: Acridoidea: Pamphagidae) from China

The complete mitochondrial genomes of three species of Haplotropidini were sequenced, annotated and analyzed. Then, combined with 18 species mitogenomes of Acridoidea and 1 species of Tridactyloidea, the phylogenetic relationships were reconstructed by maximum likelihood (ML) and Bayesian (BI) methods based on PCGs. The phylogenetic relationship tree showing that Sulcotropis Yin et Chou is a valid genus and not a synonym of Haplotropis Saussure, 1888. A new species Sulcotropis xiaowutaiensis sp. nov. is described in this paper from China, it is allied to Sulcotropis cyanipes Yin et Chou, 1979, but differs from latter by median carina of pronotum cut by posterior transverse sulcus slightly, epiphallus with middle part equal both sides in high, cercus of male gradually widened at base, interspace of mesosternum narrowed in the base slightly and subgenital plate of female oblong, hind margin with small acute angle in the middle. Type specimens are deposited in the College of Life Sciences, Hebei University, Baoding, Hebei, China.

Iphinoe indenticulata sp. nov. (Crustacea: Cumacea: Bodotriidae), a new Korean cumacean

A new species of Cumacea belonging to the genus Iphinoe Bate was collected from the Yellow Sea in Korea. The new speices Iphinoe indenticulata sp. nov. resembles I. sagamiensis Gamô, 1962 in the shape of carapace and the type of setae on the uropod peduncle. However, the new species is distinguished from congeners by having only setules on dorso-median carina of carapace. Also, the number of setae of uropodal peduncle and endopod is different from the I. sagamiensis. The new species is described with full illustration including mouthparts. A key to the Korean Iphinoe species is also provided.

Review of Lophotettix, the sole member of the subfamily Lophotettiginae Hancock, 1909 (Insecta: Orthoptera: Caelifera: Tetrigidae)

Lophotettiginae is a small, peculiar taxon of the Neotropical region, characterized mainly by median carina compresso-cristated or leaf-like crest, antennae flattened laterally and expanding from the base to the apex (incrassate shape). This subfamily has only one genus known as Lophotettix Hancock, 1909 that comprises five species. Here, we reviewed the types of the five known species, highlighting morphological aspects that distinguish the species from each other and from other tetrigids. Additionally, we also provide a pictorial identification key to Lophotettix species. Our results indicated that Lophotettiginae is a well-defined taxon and there are no synonyms among its species.

New genus of the family Delphacidae (Homoptera: Cicadina) from North America

A new genus, Euryburnia gen. nov. (type species: Megamelus magnifrons Crawford, 1914) is erected to accommodate the group of Nearctic species of the family Delphacidae erroneously placed by Hamilton (2002) in the genus Eurybregma Scott, 1875. The new genus differs from Eurybregma by narrower metope without intermediate carinae on eumetope (only median carina is developed). According to male genitalia structure the new genus is close to the genera Unkanodes Fennah, 1956 and Chilodelphax Vilbaste, 1968, but distinguished by angular (not rounded) latero-ventral lobes of pygofer and by pygofer phragme without teeth and processes. From the genus Eurybregma the new genus differs by the presence of latero-ventral lobes of male pygofer. According to presence of unique, well developed beak-shaped basal lobes of dorso-lateral plates of ovipositor (first valvifers) the new genus is distinguished within all Delphacidae. New combinations proposed: Euryburnia magnifrons (Crawford, 1914), comb. nov. (=Megamelus magnifrons Crowford, 1914), Euryburnia montana (Beamer, 1952), comb. nov., (=Eurysa montana Beamer, 1952), Euryburnia obesa (Beamer, 1952), comb. nov. (=Eurysaobesa Beamer, 1952), Euryburnia eurytion (Hamilton, 2002), comb. nov. (=Eurybregma eurytion Hamilton, 2002).

New genus and new species of the family Issidae (Hemiptera: Auchenorrhyncha: Fulgoroidea) from Southern Spain

A new genus, Dozierana gen. nov., is erected for Thionia gibbicollis Dozier, 1931 which is transferred from the family Issidae Spinola, 1839 to the family Nogodinidae Melichar 1898, subfamily Colpopterinae Gnezdilov, 2003. This new combination increases the fauna of Colpopterinae of Haiti Island up to 3 genera with 5 species. Accordingly, the family Issidae is no longer formally known from the island. Dozierana gen. nov. is characterized by wide metope, with distinct median carina and very weak sublateral carinae, upper margin of metope concave; coryphe 3 times as wide as long medially; large ocelli present; pronotum short, with 4 lateral carinae, its anterior margin strongly convex and posterior margin strongly concave; mesonotum 7 times as long as pronotum along midline, greatly elevated along median carina, with two lateral carinae joined with median one in shape of inverted “V”; fore wings wide, with wide hypocostal plate and rich cross-venation through whole wing, except subcostal area; basal cell large oblong-oval; costal vein with distinct upper keel appearing as a separate vein; clavus as long as whole wing, open; hind tibiae with single lateral spine subapically.

The water striders (Hemiptera: Heteroptera: Gerridae) of Costa Rica: new species, checklist, and new records

Brachymetra bernaldi Cordeiro, sp. nov. (Hemiptera: Heteroptera: Gerridae) from Heredia, Costa Rica, is herein described, illustrated, and compared with congeners. The new species resembles B. albinervus (Amyot & Serville, 1843), but can be separated from it by the weak median carina of the pronotum, male abdominal mediotergite I with weak lateral notches, male abdominal mediotergite VII quadrate, male abdominal segment VIII in natural position almost entirely inserted into the abdominal cavity, and paramere narrow, with acute apex. We also provide the first checklist of the Gerridae of Costa Rica and new records, based on collection material and field sampling. All totaled, 31 species representing 13 genera and six subfamilies are recorded from the country. Five species and the genera Brachymetra Mayr, 1865 and Neogerris Matsumura, 1913 are registered for the first time from Costa Rica, and new provincial records are presented for 15 other species.
