Abstract The male genitalic characters of Hexapoda are well known for their great taxonomic and systematic value. Despite insect male genitalia displaying large diversity, variation, and modification across orders, some structures are consistently present, and such characters can serve as the basis for discussion regarding homology. In the order Lepidoptera, a male genitalic structure widely known as the ‘juxta’ is present in many taxa and absence or modification of this character can be phylogenetically informative at the generic or higher level. We here focus on the systematics of the so-called ‘Taygetis clade’ within the nymphalid subtribe Euptychiina, and report an unusual case of ‘juxta loss’ in a single species, Taygetina accacioi Nakahara & Freitas, n. sp., a new species from Brazil named and described herein. Additionally, we describe another west Amazonian Taygetina Forster, 1964 species, namely Taygetina brocki Lamas & Nakahara, n. sp., in order to better document the species diversity of Taygetina. Our most up-to-date comprehensive molecular phylogeny regarding ‘Taygetis clade’ recovered these two species as members of a monophyletic Taygetina, reinforcing the absence of juxta being a character state change occurring in a single lineage, resulting in an apomorphic condition, which we report here as a rare case in butterflies (Papilionoidea).

Two New Species

We describe two new species of green pitviper from Southeast Asia that are morphologically similar to Cryptelytrops macrops, but can be distinguished from that species by genetic means, multivariate analysis of morphology and some aspects of coloration. Cryptelytrops cardamomensis sp. nov., is described from southeastern Thailand and the Cardamom Mountains of southwestern Cambodia. Cryptelytrops rubeus sp. nov. has been recorded from southern Vietnam and eastern Cambodia. These species have previously been confused with C. macrops, hence we also present here a redescription of this species, whose range is now restricted to Thailand, southern and central Laos, and northeastern Cambodia. All three species are present in Cambodia, but have disjunct ranges corresponding to three separate highland regions in southwestern (Cardamom Mountains), northeastern (western edge of the Kontum Plateau) and eastern (low elevation hills on the western edge of the Langbian Plateau) Cambodia for C. cardamomensis, C. macrops and C. rubeus respectively. However, there is still considerable morphological variation between geographically separated populations of C. macrops s.s., and greater sampling in southern and northern Thailand in particular may be required before the species diversity of this group is fully clarified.

A new species ofFergusonina(Diptera: Fergusoninidae) fly is described from terminal leaf bud galls (TLBGs) from theEucalyptus paucifloraSieb. ex Spreng. (snow gum) species complex from Australia.Fergusonina tasmaniensisNelson sp.n. is the first species from the genusFergusoninato be described from Tasmania and the fourth from this host complex.Fergusonina tasmaniensissp.n. can be distinguished from the other snow gumFergusoninaspecies by differences in adult size, markings on the mesonotum and the male genitalia, and from all other describedFergusoninaby host specificity and differences in adult colouration, setation, genitalia and the morphology of the larval dorsal shield. In a molecular phylogeny of the snow gum-inhabitingFergusoninaspecies,F. tasmaniensissp.n. was resolved as monophyletic, and sister (mean distance = 3.82%) to a clade comprisingF. daviesaeNelson and Yeates andF. omlandiNelson and Yeates (mean interspecific distance = 2.48%).

The Status

The butterfly tribe Baorini Doherty, 1886 is a large group of skippers. In this study, a total of 8 genera and 41 species of putative members of this tribe, which represent most of the generic diversity and nearly all the species diversity of the group in China, were sequenced for two mitochondrial genes and three nuclear genes (2084 bp). Phylogenetic relationships and subdivision of this tribe were investigated and the status of the genera are discussed. Partitioned maximum likelihood analyses were performed based on the combined dataset. Our results suggest that the data are split into two well-supported clades in the phylogeny tree. This analysis also represents the most complete phylogenetic analysis of the tribe Baorini in China to date, and includes several genera and species that have been previously excluded from published phylogenies of this group.
