A new genus of Australian Tetrastichinae (Hymenoptera: Eulophidae): an introduced pest of Chamelaucium uncinatum (Myrtaceae) in California

A new genus of tetrastichine eulophid, Oncastichus LaSalle, is described to contain a single new species, Oncastichus goughi Headrick and LaSalle. This species is native to Australia, and is a gall former on the Geraldton waxflower, Chamelaucium uncinatum. Oncastichus goughi was accidentally introduced into California where it causes economic damage to the Californian horticultural industry. This is the first example of a tetrastichine Eulophidae becoming an economically important introduced pest species.     

The genus Lilloiconcha in Colombia (Gastropoda: Charopidae)

The name Lilloiconcha Weyrauch, 1965 Weyrauch, W. K. 1965. Neue und verkannte Endodontiden aus Südamerika.. Archiv für Molluskenkunde, 94: 121–134.  [Google Scholar] is used tentatively for South American charopids with a reduced penis, a barely differentiated epiphallus and multicuspid marginal radular teeth. Trochogyra Weyrauch, 1965 Weyrauch, W. K. 1965. Neue und verkannte Endodontiden aus Südamerika.. Archiv für Molluskenkunde, 94: 121–134.  [Google Scholar] is considered to be a synonym of Lilloiconcha. In addition to the widespread Lilloiconcha gordurasensis (Thiele, 1927 Thiele, J. 1927. Über einige brasilianische Landschnecken.. Abhandlungen der Senckenbergischen Naturforschenden Gesellschaft, 40: 307–329. Plate 26 [Google Scholar]), Lilloiconcha costulata new species and Lilloiconcha laevigata new species are described from the Cordillera Oriental in Colombia. The distribution of Lilloiconcha gordurasensis in South America is summarized.     

Sasquaperla Hoopa , a new stonefly genus and species from northern California (Plecoptera: Chloroperlidae)

Sasquaperla hoopa , a new genus and species of Chloroperlidae, is described from adults and preemergent nymphs collected in the Coast Range of northern California. Males are characterized by the epiproct reduced to a small, tablike structure bearing stiff hairs in a narrow band along the posterior margin. Females are similar to those of Sweltsa , but the nymphs bear several erect bristles lateral to depressed hair patches on the mesosternum. Modified keys are presented for adults and nymphs.     

The Pacific Iassine cicadellid genus Thalattoscopus (Homoptera)

The Pacific Iassine genus Thalattoscopus is revised and distinguished from Batracomorphus on external and male genitalic characters. Of 21 species included, 12 are newly described and two are treated as nomina dubia. A key to species is given, four new synonymies and eight new combinations are established.     

Calileuctra , a new genus, and two new species of stoneflies from California (Plecoptera: Leuctridae)

Calileuctra is proposed as new genus in the family Leuctridae, with Calileuctra ephemera designated as the type species. All stages of Calileuctra ephemera are descpribed. Calileuctra dobryi is described in the male and female stages. Both species inhabit Mediterranean climatic region of California. A phylogenetic analysis of the genera in the family Leuctridae is given, which places Calileuctra near the genus of Perlomyia .     

The deltocephaline leafhopper genus Hishimonoides in the Indian subcontinent (Homoptera)

The genus Hishimonides and the species Hishimonoides orientalis Mahmood are redefined. Three new species of the genus, namely H. arbudae (from Rajasthan: Mount Abu), H. bougainvilleae (from Karnataka: Bangalore; Tamil Nadu: Burliar) and H. setosus (from Karnataka: Bandipur; Rajasthan: Mount Abu) are described and illustrated. A key to the seven species known in the genus is given. H. bougainvilleae was found on Bougainvillea spectabilis Willd. (Nyctaginaceae).     

The genus Monacha in the Western Caucasus (Gastropoda: Hygromiidae)

Seven Monacha species have been found in the Western Caucasus region. Six of these species are endemic there. They all belong to the subgenera Paratheba and Metatheba. Three species are new to science. M. (Paratheba) claussi, sp. n. and M. (Metatheba) subcarthusiana (Lindholm) are the only Monacha species, in which the right ommatophoral retractor sometimes crosses with the penis. This might be due to an ancestral polymorphism, atavism or a basal position of the two species within Monacha, which would mean that Paratheba is paraphyletic and Metatheba is polyphyletic. Monacha (Monacha) cartusiana (O. F. Muller), the only Monacha sensu stricto species in the Caucasus region, has probably been introduced by man. The shell and the genitalia of every species are described and illustrated. The synonyms and all Caucasian locality records are listed. The distributions of the species are illustrated on UTM-grid maps.     

The Afrotropical thermophilic ant genus Ocymyrmex (Hymenoptera: Formicidae)

The taxonomy and biology of the Afrotropical thermophilic ant genus Ocymyrmex is reviewed and updated. A new key to workers for the 37 recognized species is presented and species-groups within the genus are delimited. Revised genus-level diagnoses for all castes are given and a check-list with known distributions of all species is included. Nine new species are described. The previously known biology of the genus is reviewed in the introduction and fresh biological and ecological information on a number of species is given in the introduction and under the individual species headings.     

The genus Eriogonum Michx. (Polygonaceae) and Michel Gandoger

New species and varieties of the plant genus Eriogonum (Polygonaceae) that occur in Nevada are proposed. Eriogonum tiehmii and E. ochrocephalum var. alexanderae are endemic to Nevada, and E. lewisii is restricted to extreme northeastern Nevada and adjacent Utah. These entities belong to the subgenus Eucycla. Two varieties of E. umbellatum (of the subgenus Oligogonum) are proposed. The first, var. juniporinum , is found in eastern Nevada and in the desert ranges of southeastern California. The second is var. furcosum , which is restricted to the Sierra Nevada. One new combination is also proposed: E. nudum var. gramineum .         

Agropyron arizonicum (Gramineae: Triticeae) and a natural hybrid from Arizona

In the Pinaleno Mountains where logging has been heavy, numerous disturbed habitats have permitted frequent hybrid populations to persist. Intermediate phenotype, chromosome behavior, lack of seed set, and pollen sterility were used to interpret the status of this hybrid derivative. Introgression and/or segregation are not apparent.       

The psyllid genus Pseudophacopteron (Hemiptera: Psylloidea) from China

The Chinese fauna represents a small portion of the species diversity of the psyllid genus Pseudophacopteron (Phacopteronidae) of the world. Here, Pseudophacopteron from China is revised, and four species are recognized. Pseudophacopteron quinquipannis sp. nov. is described; Pseudophacopteron alstonium is synonymized with Pseudophacopteron tuberculatum; Pseudophacopteron album, Pseudophacopteron aphanamixis and P. tuberculatum are redescribed. Comparison is made between the four species and Phacopteron. The latter possesses unsplit fields of radular spinules in cells m₁, m₂ and cu₁ of the fore wing, and thick tibiae covered by dense long and slender setae, which are different from Pseudophacopteron.
