The male genitalia and wing venation of Austronepa, Laccotrephes, and Ranatra are described and compared. A general description is given of the male of Austronepa angusta (Hale). It is concluded that the male genitalia do not seem to provide reliable subfamily or tribal characters in the genera studied.

AbstractA re-investigation of the taxonomic status of Bombus franklini (Frison) is described. Comb architecture was found to be characteristic of other taxa within its subgenus (Bombus s.s.) but multivariate analysis of wing venation data taken from queens gave a clear separation of franklini from other species within the subgenus. The male genitalia of franklini are markedly distinct from those of B. occidentalis Green. The authors advocate retention of specific status for franklini.

Adult external morphology of the extant raptorial Mantispoidea (Insecta: Neuroptera: Mantispidae and Rhachiberothidae) is compared emphasizing the morphology of the subfamily Symphrasinae as a key group to understand the phylogenetic relationships among the members of the superfamily. Plega dactylota Rehn, 1939 is thoroughly characterized in order to exemplify the morphology of the Symphrasinae. Additionally, following a review of the literature and examination of comparative material of Dilaridae, Berothidae, Rhachiberothidae and all Mantispidae subfamilies, a new interpretation of the components of the raptorial apparatus (i.e., head, prothorax, grasping forelegs, as well as integumentary specializations) is presented. Also, wing venation for these groups is reinterpreted, and new homology hypotheses for wing venation are proposed based on tracheation and comparative analyses. Given the high morphological divergence on the genital sclerites within the Mantispoidea, plus the confusing previous usage of neutral terminology and terms referring to appendages across taxonomic and morphological studies, we attempt to standardize, simplify, and situate terminology in an evolutionary context under the “gonocoxite concept” (multi-coxopod hypothesis). The remarkable morphological similarity of the genital sclerites of Symphrasinae and Rhachiberothidae (sensu U. Aspöck & Mansell 1994) with the Nallachinae (Dilaridae) was taken as a starting point to understand the morphology of other Mantispidae subfamilies. Based on these morphological comparisons, we provide a revised phylogenetic analysis of Mantispoidea. This new phylogenetic analysis supports a sister group relationship between the family Rhachiberothidae, comprising Rhachiberothinae and Symphrasinae, and the family Mantispidae, including the subfamily Mantispinae and its sister taxa Drepanicinae and Calomantispinae, which may represent a single subfamily. Based on these analyses, raptorial condition probably evolved a single time in these insects and subsequently became diversified in the two sister clades of the raptorial Mantispoidea.

The North American leafhopper genus Erasmoneura Young was described as a subgenus of Erythroneura Fitch by Young (1952) to comprise the informal Erythroneura vulnerata Fitch species group previously recognized by Beamer (1938, 1946). Erasmoneura was recently elevated to generic status (Dietrich & Dmitriev, 2006) and revised (Dmitriev & Dietrich, 2007). In this paper, the male of Erasmoneura bipentagona (Beamer), previously known only from the female holotype and placed in the genus based on external similarity and features of wing venation (Young, 1952; Dietrich & Dmitriev, 2006; Dmitriev & Dietrich, 2007, see also the note for the species below), and a new species are described. A key for identification of all 13 species of the genus is provided. The key is based mainly on male genitalia characters. Although individual species have a characteristic color pattern, details and intensity may be highly variable both inter- and intraspecifically.

The genus Frisilia Walker of the world is reviewed, with all of the 31 known species including two new species, F. cornualis sp. nov. and F. nesiotes sp. nov. The genus can be divided into the nesciatella and the anningensis species groups, on basis of the presence or absence of a median process of the juxta in the male genitalia. For all of the known species, we provide photos of adults and their male or female genitalia, all available taxonomic information including original references, type localities, type depositories, sources of available specimens, geographical distributions, and some recently collected data of the species. Frisilia striapunctata Wu is transferred to the genus Homaloxestis Meyrick, due to the normal slender labial palpus of the male and its wing venation. Frisilia drimyba Diakonoff (1967), known from the Philippines, is excluded from the genus Frisilia because of its lanceolate forewing with sharply pointed apex.

The terminology pertaining to the structure of the male genitalia of the Hymenoptera has been subject to much confusion. Several systems, many purely descriptive in nature, have previously been set forch. Others were based on the various concepts of the ontogeny of the male genitalia, or on the comparative morphology of the adults. The investigation reported here began as an attempt to synthesize the various terminolopies and to evolve a workable set of terms pertaining to the structure of the male genitalia of the megachilid bees. Accordingly, a study was conducted on the myology of the group with the thought that perhaps an understanding of the comparative musculature might be of value in determining the homologies of the insect genitalia. This paper reports the results of a phase of the investigation on the morphology of the male metasoma, the muscular mechanism of the male metasoma and genitalia, and the gross structure of the internal reproductive organs of Megachile (Phaenosarsus) fortis Cresson. A second portion of the study, pertaining to the comparative morphology of the male genitalia and associated sterna of the Mecgachilidae, will be published later.

 Two new genera, Sakakidikra n. gen. and Tricella n. gen., of tribe Dikraneurini McAtee are described from Ecuador, each based on a single new species, Sakakidikra jazminae n. sp. and Tricella antonellae n. sp. Both new genera described have only three apical cells in the forewing, an unusual characteristic in Typhlocybinae, but given the differences in the forewing and hind wing venation and male genitalia characters we consider it more appropriate to place the specimens in two separate monotypic genera.

Apiformyia gen. nov. (Diptera: Bombyliidae) is described based on a large series of specimens from the Northern Territory of Australia. The specimens represent a single new species A. australis sp. nov. The genus belongs to the Bombyliinae, and has remarkable anatomical affinities to the New World genus Heterostylum Macquart. In particular, the head of Apiformyia has a sinuous posterior eye margin, but lacks a line bisecting the facets as found in most Anthracinae that also share such an eye margin. A sinuous posterior eye margin is uncommon in the subfamily Bombyliinae, being only found in Heterostylum and four other genera found in the New World, Afrotropical and Palaearctic regions. Additionally, Apiformyia shares with Heterostylum alone an unusual wing venation, with cell R 5 closed, and the apex of cell dm-cu meeting the fork of M 1 and M 2 , there being no stem of M 1+2 . The male genitalia of Apiformyia are generalized bombyliine in form, and do not share the particular unique features of Heterostylum such as the large recurved epiphallus and the gonostylus with apical beak-like process. The female genitalia of Apiformyia lack the sand chamber, acanthophorite spines and presents spermathecae with elongated bulbs, spermathecal ducts more than twice as long as sperm pump and sclerotized collars well developed, also differentiating the genus from Heterostylum.
