New Genus And Species

A new genus and species of the cleroid family Lophocateridae are described and illustrated from the mid-Cretaceous amber of northern Myanmar. Gracilenticrus burmiticus Yu, Kolibáč & Ślipiński gen. et sp. nov. is unique among Lophocateridae in the tiny body size, frontoclypeal suture and antennal grooves absent, symmetrical antennal clubs, protrochantin reduced, tarsal claws small and widened at base. A key to the species of Mesozoic Lophocateridae is also provided. Morphological characters of the newly discovered Gracilenticrus were analyzed together with representatives of 43 extant genera of Cleroidea (broadly defined Trogossitidae) in a matrix of 91 characters. Gracilenticrus burmiticus was resolved as a member of Lophocateridae. The discovery of a diverse fauna of Lophocateridae in the mid-Cretaceous sheds a new light on the early evolution of superfamily Cleroidea.

Claviplatysgen. n. and its type species C.henryisp. n. (Hemiptera: Heteroptera: Plataspidae: Plataspinae) are described from Kerala, India. The new genus is related to the Indomalayan genera Heterocrates Amyot & Serville, 1843, Cratoplatys Montandon, 1894, and Cronion Bergroth, 1891, but differs from them and all other plataspid genera by the peculiarly modified antenna. The morphological characters and systematic relationships of the above genera are discussed.

A new genus and species of goby, Gymnesigobius medits sp. nov., is described from the western Mediterranean slope bottoms at the Balearic Islands. The new goby belongs to the Gobius-lineage (Gobiinae). Examination of the single known specimen exhibits a unique combination of morphological characters which could not be fitted to any known genus. Gymnesigobius gen. nov. is morphologically distinguished from all other genera in the Gobius-lineage by the following combination of characters: chin without fold or barbels; mouth terminal with anterior tip above horizontal level of lower eye edge; predorsal area and first dorsal fin base naked; pelvic fin anterior membrane well developed; head with anterior oculoscapular and preopercular canals, posterior oculoscapular canal absent; pores of head canals enlarged, e.g. pores α and ρ larger or of about the same size as interspaces to pore β; six transverse suborbital rows of sensory papillae, four continuous suborbital rows in front of row b, fifth row divided in three parts but in front of row b, sixth row just as superior part above row b and below pore α; longitudinal suborbital row b barely reaching forward to the vertical from posterior edge of eye. A full description of the new genus and species is provided. The new species, collected at a depth of between 344 and 364 m (mean depth of 354 m), is one of very few gobiid species found at bathyal depths.

Abstract Burmese amber is well known for preserving unique extinct lineages of insects. Here, we describe a new fossil beetle in its larval stage from Burmese amber. Bayesian and parsimony phylogenetic analysis of 50 morphological characters support this fossil as being sister to both the tribes Dineutini and Orectochilini, representing an extinct stem lineage in Gyrininae. It is described here as a new genus and species of whirligig beetle, Chimerogyrus gigagalea gen. & sp. nov., a taxon that preserves remarkable intermediate features between the whirligig beetle tribe Gyrinini and the crown Orectochilini and Dineutini. This new taxon preserves key features for studying the evolution of characters within the larval stage of the Gyrinidae and highlights the importance of Burmese amber for preserving both stem and crown lineages present during the mid-Cretaceous, before the end-Cretaceous mass extinction event.

Madeirasquilla tuerkayi is described as a new genus and species of the nannosquillid mantis shrimps (Stomatopoda) based on a single specimen collected from Madeira, eastern Atlantic. That specimen is remarkable by a combination of the following morphological characters: rostral plate with three sharp anterior projections; antennal protopod with two mesial and one ventral papillae; cornea subglobular; raptorial claw dactylus with 11 or 12 teeth, and with acute proximal tooth on outer margin; pleonite 6 with strong posterolateral spine and two posteriorly directed sternal spines; telson bearing smooth shield-like dorsal prominence with acute median spine posteriorly; four pairs of fixed primary teeth posteriorly on the telson; outer primary spine of uropodal protopod longer than inner primary spine. The separate position of the new genus is supported also by molecular comparison. A key to the genera of the family Nannosquillidae is proposed.

A new genus and species, Stachyops sebparri, is described from the eulittoral of Cook Strait, New Zealand and is the firstrecord of a nototanaid from one of the main islands. A very small species, it has several morphological characters that areshared with some species of the Tanaissuidae, such as a narrow mandibular molar and fewer pereopods 4–6 carpal spines,yet retains some apparent plesiomorphic features more typical of the Nototanaidae or other ‘basal’ paratanaoideans. Aphylogenetic analysis does group it with the Nototanaidae sensu Bird & Larsen, but more phylogenetic studies of these two families are needed to clarify their composition, relationships, and validity.

Megadrypta mirabilis n. gen. n. sp. from Guangdong (China) is described. The new genus is distinguished from all known genera by a combination of large body size, pronotal bead well marked, sloping shoulders, reduced hind wings, smooth claws and stylomeres, and a large number (7–8) of periscutellar pores. Some remarks are made upon the relationships with the other genera of Dryptini, raising to the genus rank the taxa Nesiodrypta Jeannel, 1949 and Prionodrypta Jeannel, 1949, formerly regarded as subgenera of Drypta Latreille, 1796. A new key to all the genera of this tribe is proposed.

Jehol Biota

Mathesius liaoningensis, a new genus and species of Cleroidea, probably relative of clerid or thaneroclerid branches of the superfamily, is described from the Lower Cretaceous; it belongs among the oldest and the best preserved cleroid fossils that have been known so far. The unique specimen was found in Yixian Formation (ca. 125 Ma) near Huangbanjigou Village, Beipiao City, Liaoning Province, NE China and belongs to the famous Chinese Jehol Biota. A classification of Mathesius liaoningensis gen. et sp. nov. within Cleroidea is based on cucujiform aedeagus with distinct medial apodeme (strut) and probably paired struts of the phallobase, pentamerous mesoand metatarsi, narrowly separated proand mesocoxae, metacoxae extending laterally to meet elytra. A possible relationship with the clerid or thaneroclerid branches is based on predacious mandibles, absence of large spines in tibiae, lobes at least in mesoand metatarsomeres 2–3 (probably 1–4), probably six visible abdominal ventrites, and shape of body. With the exception of the aforementioned features, the well-preserved fossil shows interesting morphological characters which are figured in detail and discussed in the context of morphology of some recent cucujiform families.

A new genus and species of endogen cholevid beetles (Kosaniniella javorensis n. gen., n. sp) has been diagnosed and described from under stones in the valley of Suvodol, village of Debelja, near Nova Varos, Mt. Javor southwestern Serbia. This new genus clearly differs from all other closely related genera in the following correlative traits: Body size presence/absence of eye spots; length of distalmost antennomere; form of antennomere VIII; punctuation of elytra; presence/absence of sutural striae shape of elytra; form of aedeagus; shape of aedeagal sides; shape of parameral apex; form of paramerae; distribution of parameral setae; shape of anterior inner parameral seta; form of median part of copulatory piece length of basal bulbus; and form of spermatheca. Kosaniniella n. gen. belongs to a separate phyletic lineage which includes two other phenetically close genera, Magdelainella Jeannel and Knirschiella Gu?orguiev. The new genus is present in southwestern Serbia only, while Magdelainella inhabits Serbia and Bosnia and Herzegovina. Knirschiella is given full generic status in the present paper; its members are known from Albania. The Kosaniniella-Magdelainella-Knirschiella complex is probably of early Tertiary age, its species having originated during the Alpine Orogeny, which affected vast areas of the Balkan Peninsula, including the Dinarids otherwise their terra typica.
