Characters primarily associated with the male genitalia, in particular the number and placement of spiniforms on the movable process (finger) of the clasper, are used for species discrimination. A key to the males of the 15 species and subspecies is provided, including illustrations of both males and females.        

Description of the female of Phalacropsylla hamata (Siphonaptera: Hystrichopsyllidae)

The previously unknown female of Phalacropsylla hamata Tipton & Mendez is described and an allotype is designated. A key is provided to aid in distinguishing females of this genus.     

Description of a new Phalacropsylla and notes on P. allos (Siphonaptera: Hystrichopsyllidae)

Phalacropsylla morlani, from New Mexico is described as new to science and figured. It is separable from the other species in the genus by the possession of 18 spines in the pronotal comb and by the distinctive shape and setation of the male distal arm of sternum IX. Other species in the genus have 14 to 16 spines in the pronotal comb. Host and distributional records for P. allos are given.     

Two new species of fleas of the genus Meringis (Siphonaptera: Hystrichopsyllidae)

Two new species of Meringis are described. Meringis disparalis, n. sp., has been most commonly taken from Dipodomys merriami but has also been taken from D. ordii and Onychomys leucogaster. Collection localities include the counties of Dona Ana, Eddy, and Luna in southern New Mexico. Meringis facilis, n. sp., has been taken from D. ordii, several other rodents, and Sylvilagus audubonii. Collection localities include Crowley County, Colorado, and Bernalillo, Chaves, and Valencia counties in New Mexico. A key to the species of ♂ Meringis is given.     

Revision of the genus Pseudodiphascon (Tardigrada,Macrobiotidae), with the erection of three new genera

A flexible but non-annulated buccal tube was used to erect the subgenus Pseudodiphascon, later raised to genus level (type species Macrobiotus inflexus). However, the presence of a flexible (but non-annulated) buccal tube in the holotype and paratype is due to the moulting simplex stage of both animals. Therefore Macrobiotus inflexus must be considered species dubia. The other species to date attributed to Pseudodiphascon differ from the type species of the genus in the presence of a pharyngeal tube that appears annulated. Because of this and other characters, they do not conform to the definition of Pseudodiphascon and cannot be attributed to this genus, which must be considered genus dubium. The characters of the claws and of the buccal—pharyngeal apparatuses led us to describe three new genera: Biserovus gen. n.: claws without a differentiated basal portion, annulated pharyngeal tube, peribuccal lamellae present; Minilentus gen. n.: claws of ‘hufelandi type’, annulated pharyngeal tube, peribuccal lamellae absent; Insuetifurca gen. n.: claws of modified' hufelandi type, annulated pharyngeal tube, peribuccal lamellae present, stylet furcae of a peculiar shape. Pseudodiphascon diphasconides lacks annulation in the buccal tube and is transferred to the genus Minibiotus.     

A revision of Eumedonus H. Milne Edwards, 1834 and Gonatonotus White, 1847 (Crustacea: Decapoda: Brachyura: Eumedonidae), two genera of crabs symbiotic with sea urchins

The eumedonid genera Eumedonus H. Milne Edwards, 1834 and Gonatonotus White, 1847, are revised. Members of both genera are obligate symbionts with sea urchins. Eumedonus is separated from Gonatonotus mainly by the presence or absence of crests on the merus of the ambulatory legs. Eumedonus, as here defined, contains five species, viz. E. niger H. Milne Edwards, 1834 (type species), E. vicinus Rathbun, 1918, E. zebra Alcock, 1895, E. brevirhynchus n. sp., and E. intermedius n. sp. Gonatonotus, as here re-diagnosed, includes three species, viz. G. pentagonus White, 1847 (type species), G. granulosus (MacGilchrist, 1905), n. comb. and G. nasutus n. sp.     

Mexican cardiochiline genera (Hymenoptera: Braconidae), including a preliminary assessment of species-groups in Toxoneuron Say and Retusigaster Dangerfield,Austin and Whitfield

The Mexican species of the braconid subfamily Cardiochilinae are reviewed. Forty-five species are recognized from Mexico, though many of these remain undescribed. Seven species are described as new and one, Toxoneuron levis (Mao), is redescribed. Species-groups are delineated for the New World species of Toxoneuron Say and Retusigaster Dangerfield, Austin and Whitfield and the genera are re-defined with respect to one another. Two new species are described in both Retusigaster and Toxoneuron. The atypical nature of the two included in Toxoneuron is discussed. Hansonia, Heteropteron and Schoenlandella are newly recorded for Mexico with one new species described for each. The placement of all New World species previously included in Schoenlandella is discussed, and several of these species are returned to Cardiochiles s. s. Distribution patterns of the Mexican species are discussed and an annotated key is presented for the 28 described species recorded from Mexico.     

Fleas (Siphonaptera: Ceratophyllidae, Ctenophthalmidae) from rodents in five southwestern states

Nine species of fleas were collected incidental to a survey of rodents for molecular studies in Arizona, Colorado, New Mexico, Texas, and Utah, south of latitude 38° N. Three species were parasites of woodrats, Neotoma spp.: Orchopeas neotomae Augustson was confirmed for Texas, and the distribution patterns of O. agilis (Rothschild) and O. schisintus (Jordan) were more clearly defined. Four species were parasites of mice, Peromyscus spp.: Aetheca wagneri (Baker) was a new flea for P. gratus Merriam, the distribution of O. leucopus (Baker) was extended to far west Texas, Plusaetis sibynus (Jordan) was new for Utah and N. lepida , and the range of Stenoponia americana (Baker) was extended west of the Continental Divide in New Mexico. Other species included Foxella ignota (Baker) and Meringis dipodomys Kohls.     

The genera Parotoplana Meixner, 1938 and Parotoplanella Ax, 1956 (Platyhelminthes: Proseriata) in southern Spain

Collecting in southern Spain yielded five species of Parotoplana and one species of Parotoplanella (Proseriata: Otoplanidae). Four species of Paratoplana proved to be new to science. Parotoplana cucullata sp. n. is distinguished by the shape of the lateral spines in the copulatory organ and in the presence of a “glandular organ” around the distal portion of the female duct. Parotoplana fretigaditani sp. n. is similar to P. procerostyla Ax, 1956 Ax, P. 1956. Monographie der Otoplanidae (Turbellaria): morphologie und systematik.. Akademie der Wissenschaften und der literatur Abhandlungen der Mathematisch‐Naturwissenschaftlichen klasse, 13: 159–278.  [Google Scholar] in the general arrangement of spines, but their fine morphology is distinctive. Parotoplana varispinosa sp. n. differs from P. capitata Ax, 1956 Ax, P. 1956. Monographie der Otoplanidae (Turbellaria): morphologie und systematik.. Akademie der Wissenschaften und der literatur Abhandlungen der Mathematisch‐Naturwissenschaftlichen klasse, 13: 159–278.  [Google Scholar] in the shape and number of spines. Parotoplana mastigophora sp. n. has a unique morphology of the stylet, and the spines of the girdle markedly differ in size and shape. The karyotype of P. cucullata sp. n. (n = 6) is described. In addition, Parotoplana primitiva and Parotoplanella heterorhabditica, previously known from the Atlantic coast of France and north‐west Mediterranean, respectively, were found. The high proportion of new species demonstrates the present poor state of knowledge of interstial meiofauna.     

The Old World genera of braconine wasps (Hymenoptera: Braconidae)

An illustrated key is provided to the Old World genera of Braconinae. In addition, notes are provided on each genus and on a number of characters employed in the key. One new tribe and five new genera based on two existing and three new species are described. The new taxa are as follows: Angustibracon gen. nov. from India (type-species: Bracon leptogaster Cameron, 1899), Bathyaulacini tribus nov. (type-genus: Bathyaulax Szépligeti, 1906), Cassidibracon gen. nov. from West Africa (type-species: Cassidibracon castus sp. nov.), Serraulax gen. nov. from the Afrotropical Region (type-species: Iphiaulax lukombensis Cameron, 1912), Virgulibracon gen. nov. from Australia (type-species: Virgulibracon vulsus sp. nov.) and Vomeribracon gen. nov. from New Guinea (type-species: Vomeribracon amplipenniger sp. nov.). The Pseudodicrogeniini Achterberg, 1976 is synonymized with the Euurobraconini Ashmead, 1900. Ten new generic synonymies are reported: Atanycolimorpha Viereck, 1913 (= Cyanopterus Haliday, 1835), Caenoprymnus Cameron, 1909 (= Soter Saussure, (1890) 1892), Coelodontus Roman, 1912 (= Trigastrotheca Cameron, 1906), Cynodobracon Cameron, 1912 (= Nedinoschiza Cameron, 1911), Iphioilta Ramakrishna Ayyar, 1928 (= Chaoilta Cameron, 1899), Kenema van Achterberg, 1983 (= Trigastrotheca Cameron, 1906), Odontopygia Enderlein, (1918) 1920 (= Trigastrotheca Cameron, 1906), Paraspinaria Cameron, 1905 (= Mesobracon Szépligeti, 1902), Pseudoglyptomorpha Tobias, 1957 (= Pseudovipio Szépligeti, 1896) and Glyptomorpha (Remorpha) Shestakov, 1932 (Pseudovipio Szépligeti, 1896).     

Phylogenetic evaluation of the tropical Camptotypus genus-group (Hymenoptera: Ichneumonidae), with a key to the world genera

The phylogeny of the disjunct pantropical Camptotypus genus-group (Hymenoptera, Ichneumonidae, Pimplinae) was reconstructed using 40 morphological characters.The monophyly of many established genera (Parvipimpla, Clydonium, Odontopimpla) was found to be supported, but Hemipimpla was found to nest within Camptotypus and has thus been treated as a junior synonym of it (syn. n.). A group of undescribed Neotropical species were found to form a separate monophyletic group, herein referred to as Genus A. Species of the Neotropical genus Zonopimpla formed a basal paraphyletic grade which could not satisfactorily be resolved into discrete monophyletic units. Rather than subsuming all the more derived genera within one large group, or attempting to erect numerous new and probably ephemeral genera (for isolated species of Zonopimpla), we propose the retention of this grade-group as a separate genus at present. The host utilization patterns of the genus-group, and the biogeography of the genus-group are discussed. The group is hypothesized as having originated and radiated in the Neotropics, as ectoparasitoids of weakly concealed lepidopterous hosts. One lineage, Clydonium, has become specialized at attacking hosts in woody galls where it utilizes coleopterous as well as lepidopterous hosts. The Old World genera (Camptotypus and Parvipimpla) comprise a monophyletic group and are suggested to have originated from a single dispersal event across the widening Atlantic. No evidence for either a southern or northern circum-polar dispersal was observed in this entirely tropical genus-group. One lineage in the Afrotropical region has switched from attacking lepidopterous hosts, to attacking pre-pupal and pupal polistine vespids.     

The Old World genera of Meloidae (Coleoptera): a key and synopsis

This paper reviews the 77 Old World genera of blister beetles (Coleoptera: Meloidae). Included is a key to genera and a synopsis of each genus. The generic synopses incorporate synonyms, number of species, geographic distribution, and the most significant references on taxonomy, life history and certain other topics. Additional notes are appended to several of the generic treatments. Formal nomenclatural changes include two new generic synonymies, one new status, three new combinations and the transfer of one subgenus.     

New synonymy, new combinations, and new species of North American Pityophthorus (Coleoptera: Scolytidae), Part II

Four new species of Mexican Pityophthorus in the Lautus group are described: P. indefessus (Jalisco), P. inhabilis (Guerrero), P. tutulus (Veracruz), and P. vegrandis (Quintana Roo) and a new locality record is given for P. corruptus Wood.     

A re-assessment of the genera Holorusia Loew (=Ctenacroscelis Enderlein), Ischnotoma Skuse and Zelandotipula Alexander (Diptera: Tipulidae), with notes on their phylogeny and zoogeography

Summary

A short historical background to the genera considered is given. A review is made of a number of characters which had previously only been treated inconsistently, or not at all. As a result, the old-world genus Ctenacroscelis is merged with Holorusia sensu stricto, as represented by the isolated Californian type-species. All other species previously referred to Holorusia sensu lato are redistributed to two genera; the tropical South American and New Zealand forms are united into Zelandotipula; the Chilean element and the Australian species are united into Ischnotoma, the name Icriomastax Enderlein being resurrected as a subgenus to receive most of the Chilean species.

Tentative phylogenetic and zoogeographic observations are made. Holorusia and Ischnotoma are considered and discussed as sister-groups, whilst Zelandotipula is believed to be only distantly related. Zoogeographically Holorusia is seen as a successful Asiatic genus; Ischnotoma as a receding group, with extreme southern-continental distribution, having had a much wider distribution as indicated by the European Oligocene fossil Holorusia vasifera, transferred here to Ischnotoma. Zelandotipula is viewed as an essentially Neotropical genus, which has made one ‘invasion’ of New Zealand, probably in the geologically recent past.

Résumés of the principal features of the re-defined genera are given, together with systematic notes on certain species, and species catalogues giving distributions and all new name combinations.     

Taxonomy of the bryozoan genera Oncousoecia,Microeciella and Eurystrotos (Cyclostomata: Oncousoeciidae)
