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.

AbstractA re-investigation of the taxonomic status of Bombus sandersoni Fkln. is described. Using multivariate analysis of wing venation data taken from previously identified museum specimens, a non-overlapping separation between sandersoni, B. frigidus F. Sm., and B. vagans F. Sm. was obtained. The Cresson lectotype of B. couperi appears in some respects intermediate between frigidus and sandersoni. Therefore the authors advocate retention of sandersoni as the valid name for the species, while admitting the possibility that this taxon may turn out to be a clinal variant of frigidus.

Two New Species

The genus Agrotera Schrank, 1802 is revised for Australia and the generic definition is refined based on the male genitalia. The genera Leucinodella Strand, 1918 stat. rev. with L. leucostola (Hampson, 1896) comb. nov., Nistra Walker, 1859 stat. rev. with N. coelatalis Walker, 1859 comb. rev., Sagariphora Meyrick, 1894 stat. rev. with S. magnificalis (Hampson, 1893) comb. nov., and Tetracona Meyrick, 1884 stat. rev. with T. amathealis (Walker, 1859) comb. rev. and T. pictalis Warren, 1896 comb. rev. are removed from synonymy with Agrotera, as they lack the synapomorphies of Agrotera. Two new species, Agrotera genuflexa sp. nov. from Northern Territory, Queensland and New South Wales, and A. longitabulata sp. nov. from Queensland, are described. The taxonomic status of the Australian species of Agrotera is discussed, and a key to all species, based on males, is provided. The adults and genitalia of the new species and some related species are figured.

Brasilocaenis atawallpa was recently described based on male imago from Colombian Amazon. The original description does not contain a designation of type specimens or locality, and it just states that the type series was studied in order to perform the cladistic analysis. In this context, we herein designate the lectotype and paralectotypes of B. atawallpa and describe its nymphal stage. The nymphs were associated to B. atawallpa by the male genitalia extracted from mature nymphs. The nymphal stage of B. atawallpa can be differentiated from others known nymphs of the genus by absence of pointed microspines on opercular gill, fore coxa without projection, middle coxa with well-developed and semicircular projection, hind coxa with finger-like projection, fore and middle tarsal claws without denticles and hind margin of the ninth sternite almost straight.

Isozyme electrophoresis and morphological comparisons were used to examine 40 populations of the skink Lampropholis delicata from eastern Australia. Four electrophoretically distinct forms were recognised amongst the sampled populations. Morphological comparisons were able to separate the four population groups only when meristic and colour characters were combined and compared by means of multivariate analysis. The taxonomic status of L. delicata was stabilised by nominating a neotype for the species, collected from the type locality.

A New Species

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.

Abstract The lesser Egyptian jerboa Jaculus jaculus, is a member of the subfamily Dipodinae, known to have a number of subspecies. Previous studies of J. jaculus from North Africa found various morphological forms of unknown taxonomic status, which are frequently grouped into two taxa: J. jaculus and J. deserti. We assessed the taxonomic status of this taxon in Tunisia using allozymic (phylogenetic analysis of 23 genetic loci encoding 16 enzymatic proteins) and morphological (multivariate analysis of 13 craniodental characters) analyses of 136 J. jaculus specimens collected from seven localities within its distribution range. Allozymic analysis clearly indicated the existence of two distinct groups of J. jaculus, with a mean genetic distance (D) value of 0.99 and FST=0.52. Individuals within the two groups did not show any obvious geographical structuration, even within the Matmata locality which represents the meeting point for the two groups where they were found in sympatry. Additionally, morphometric analysis of 13 craniodental characters was clearly separated the two groups. These results were obtained over a very restricted area of the total distribution of J. jaculus and strongly suggest the occurrence of two separate and often sympatric species within the currently accepted J. jaculus in Tunisia: J. jaculus and J. deserti .

General Description

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.

 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.
