描述了在广西发现的苦苣苔科一新属和一新种,即文采苣苔属Wentsaiboea D. Fang & D. H. Qin及文采苣苔W. renifolia D. Fang & D. H. Qin, 并提供墨线图。文采苣苔属的柱头外形略似长檐苣苔属Dolicholoma D. Fang & W. T. Wang, 不同在于前者叶肾形,基部心形,具掌状脉,花冠斜钟状,裂片圆形,雄蕊和退化雄蕊着生于冠筒近基部。新属在体态上还接近小花苣苔属Chiritopsis W. T. Wang, 但前者叶具掌状脉,冠筒钟状,远轴侧膨胀,柱头马蹄形;在后者叶具羽状脉,冠筒筒状,不膨胀,柱头下唇倒梯形至线形。

Austinogebia, a new genus in the Upogebiidae and rediagnosis of its close relative, Gebiacantha Ngoc-Ho, 1989 (Crustacea: Decapoda: Thalassinidea)

New material described recently permits the separation of six upogebiid species into the new genus Austinogebia, for which the diagnostic characters and a key are presented. The new taxon is compared to its close relative, Gebiacantha Ngoc-Ho, 1989, and the opportunity is taken to rediagnose the latter.     

Ramicandelaber, a new genus of the Kickxellales, Zygomycetes

Ramicandelaber, a new genus of Zygomycetes is erected to accommodateRamicandelaber longisporus sp. nov. The fungus has hyphal septa with median plugs and forms homologous structures to sporocladia and pseudophialides. These characteristics suggest that it belongs to the Kickxellales, Zygomycetes.     

New Aradidae from Ecuador (Hemiptera,Heteroptera, Aradidae)

As an addition to the presently poorly known aradid fauna of Ecuador, 3 new genera and 4 new species are described: Osellaptera setifera gen. n., sp. n.; Kormilevia ecuadoriana sp. n. both belonging to Mezirinae; and Carventinae Cotopaxicoris cruciatus gen. n., sp. n. and Onorecoris piceus gen. n., sp. n. An updated key is provided for all species of the Neotropical genus Kormilevia Usinger & Matsuda, 1959.     

Sievoides kocyigiti n. gen., n. sp., Mesoendothyra altineriana n. sp. and Kurnubia feleensis n. sp. from Kimmeridgian shallow water limestones intercalated with alkaline igneous rocks, Western Taurus, Turkey

In the framework of the palaeogeographical reconstruction of the Western Taurus during Jurassic, the study of northern and eastern boundary of the Taurids started. Detailed facies analysis evidenced the position of the Barla Dag ramp between two elevated areas: the southern rimmed shelf extension of the platform system and the northern neritic-beach-land plain. In the basal biostratigraphical and ecological characteristics of the Balcikhisar volcano-sedimentary sequence, correlated with the Fele outcrop, one genus and three new species of foraminifers have been found: Sievoides kocyigiti n. gen., n. sp. and Mesoendothyra altineriana n. sp. from neritic environment, and Kurnubia feleensis n. sp. from rimmed shelf lagoon. Both carbonate sedimentary deposits are intercalated with spilitic-basalt pillow lava flows. The age of the new three species is Kimmeridgian, controlled by some foraminifer golden hooks.     

Tabanidae (Diptera) of Amaz?nia XXI. Descriptions of Elephantotus gen. n. and E. tracuateuensis sp. n. (Diachlorini) from the Brazilian coast

Elephantotus, a new genus of Tabanidae from the Amazon coast, Brazil, is described based on a new species E. tracuateuensis. Five females were collected in Pará State, and a male in Maranhão State. Arguments are presented for separating the new genus from Dasybasis, as well as the possibility of its occurrence being related to the nesting sites of coastal birds. The new species is characterized by its large size (x = 2.15 cm, n = 5 females), glabrous eyes, reddish-brown tegument, light brown frontal callus not touching the edges of the eyes, extending up to the vertex that has traces of ocelli, basal plate of the antennal flagellum with obtuse angle, without a tooth or spine, wings hyaline, with brown basal cells, without appendix in the fork of vein R₄₊₅, and genital furca wide with extended flaps.     

A NEW GENUS AND TWO NEW SPECIES OF CATANTOPIDAE FROM HUNAN PROVINCE, CHINA (ORTHOPTERA: ACRIDOIDEA)

Abstract Two new species of the grasshopper family Catantopidae were discovered from the Mangshan National Natural Reserve at the southern tip of Hunan Province. One of them constitutes a new genus, Yiniu , which is close to Oxya Audinet-Serville. They are described as below.
