Three new species of Fergusonina (Diptera: Fergusoninidae) flies are described from terminal leaf bud galls on Eucalyptus L'Hér. from south eastern Australia. Fergusonina omlandi Nelson and Yeates sp. nov. is the first species of fly from the genus Fergusonina to be described from the Eucalyptus pauciflora Sieb. ex Spreng. (Snow Gum) species complex; although another two species occur in sympatry on this host at higher elevations. Fergusonina omlandi sp. nov. can be distinguished from the latter by differences in adult size and markings on the mesonotum and morphology of the dorsal shield of the larva. The other new species, Fergusonina williamensis Nelson and Yeates sp. nov. and Fergusonina thornhilli Nelson and Yeates sp. nov. are the first flies to be described from Eucalyptus baxteri (Benth.) Maiden & Blakely and Eucalyptus dalrympleana Maiden, respectively. These two species can be distinguished from all other described Fergusonina by host specificity, adult colour and setation and morphology of the dorsal shield.

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).

A small freshwater prawn in Thailand has been found to be a new species and is named Macrobrachium suphanense (Decapoda: Palaemonidae). Fully grown male M. suphanense appeared very different from the most closely related male of M. sintangense: size smaller, second pereiopod smaller and less robust, rostrum form different and, in females, fewer eggs. Less closely related, fully grown M. dolatum has sharper distal cutting edge on fixed finger and M. hungi has longer rostrum than M. suphanense. DNA analyses put M. suphanense, M. sintangense and M. nipponense in the same clade with M. nipponense sister to the other two. Two more clades consist of M. dienbienphuense and M. niphanae on the one hand and M. lanchesteri and M. rosenbergii on the other. The relationship among the three clades is not clearly resolved.

Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

We describe a new frog species of the Spinomantis bertini species complex based on congruent genetic evidence from mitochondrial and nuclear DNA sequences as well as minor morphological differences. A molecular phylogeny derived from the mitochondrial 16S rRNA gene revealed that Spinomantis mirus sp. nov. is sister to a clade containing the other two described species of the species complex, S. bertini and S. beckei, but strongly differentiated from these two species by 8.1–9.8% pairwise distances in this gene. DNA sequences from two nuclear genes revealed that S. mirus sp. nov. shares no alleles with these two species. Phenotypically, S. mirus sp. nov. differs from the other species of the complex by its larger size and some aspects of its coloration, including clear mottling on the flanks, tri-color banding on the legs, and distinct brown dots on the dorsum. The new species is so far only known from Pic d’Ivohibe Special Reserve. Its distribution thus appears to not overlap with those of the other two species, which as far as known are restricted to the Andohahela Massif in the extreme South-East of Madagascar, at a distance of about 250 km from Ivohibe.

Six species of the genus Rhabdosciadium (Apiaceae) were studied by molecular phylogenetic analysis. The taxonomic status of each of them has been confirmed, the genus Rhabdosciadium turns out as a well-supported monophyletic group closely related to the genera Aegopodium, Caropodium, Carum, Falcaria, Fuernrohria, Gongylosciadium, Grammosciadium s.s., Hladnikia, Olymposciadium, etc. Rhabdosciadium anatolyi sp. nov. is described and illustrated as a new species from Hakkâri province, eastern Turkey. It differs from the other taxa of the genus, in addition to its unique geographical range, in the large terminal leaf lobes with regularly serrated margin, mainly ternate primary basal segments of leaves, and long internodes.

A new species of Pomponia Stål, 1866 (Hemiptera: Cicadidae) from the P. linearis group is described from the Western Ghats of southern India. The hitherto unknown species, P. pseudolinearis sp. nov., is easily diagnosed from the other Pomponia species of the Western Ghats based on the unique structure of its male genitalia, low to mid-altitudinal distribution, and the characteristic male song. The new taxon is a member of the P. linearis species group according to its morphology and the distinctly protruding paramedian basal pygofer lobe suggests its affiliation to the linearis species complex inside the P. linearis species group. The divergent basal lobes of pygofer of males of this species are the critical characteristic feature that can be used to distinguish it from all the other members of the P. linearis species complex. It appears that this cryptic, common, and widespread species of the southern Western Ghats region was confused with P. linearis in the past. Pomponia linearis may not occur in the Western Ghats and its records are possibly a result of erroneous identification due to species lumping with similar taxa of linearis species complex distributed from Northeast India to Vietnam. In addition, some new morphometric indices are introduced. Notes on other known Pomponia species of the Western Ghats, namely P. cyanea Fraser, 1948 and P. zebra Bliven, 1964 are also provided with P. folei Fraser, 1948 treated as a nomen nudum.

Colletotrichum gloeosporioides and C. acutatum have been reported to be causal agents of anthracnose disease of rubber tree. Recent investigations have shown that both C. gloeosporioides and C. acutatum are species complexes. The identities of Colletotrichum species causing anthracnose disease of rubber tree in Hainan, China, are unknown. In this study, 106 isolates obtained from rubber tree with symptoms of anthracnose were collected from 12 counties of Hainan and identified at the species complex level based on the ITS sequences and colony morphologies. Seventy-four isolates were identified as C. gloeosporioides species complex and the other 32 isolates as C. acutatum species complex. Forty-two isolates were selected for further multilocus phylogenetic analyses in order to identify the isolates to the species level. Twenty-six isolates from the C. gloeosporioides species complex were characterized for partial sequences of seven gene regions (ACT, TUB2, CHS-1, GAPDH, ITS, ApMat, and GS), and the other 16 isolates from the C. acutatum species complex for five gene regions (ACT, TUB2, CHS-1, GAPDH, and ITS). Three species were identified: C. siamense and C. fructicola from the C. gloeosporioides species complex, and a new species C. wanningense from the C. acutatum species complex. Artificial inoculation of rubber tree leaves confirmed the pathogenicity of the three species. The present study improves the understanding of species causing anthracnose on rubber tree and provides useful information for the effective control of the disease.

Diagnoses, comparisons, photographs and distribution maps are given for three previously described Indo-West Pacific species of Trachinotus that develop spots on their sides as adults. A new species, Trachinotus macrospilus, is described from the Marquesas Islands where it is endemic and the only species of the genus present. It differs from the other spotted Indo-West Pacific species most noticeably in having adults with only one or two large spots on each side, the largest spot larger than the iris diameter, and in having no large spot positioned above the pectoral fin. An identification key is given for all Indo-West Pacific species of Trachinotus and a molecular phylogeny, including 16 of the 20 valid species of Trachinotus is presented. A neotype is designated for Scomber botla Shaw, 1803.

The genus Manfreda (Asparagaceae) contains 35 species. A species complex includes plants similar to M. gutttata, which are characterized by the protrusion of the ovary into the perigone tube. This feature was found in specimens recently collected in western Mexico. After a morphological analysis, we found that some of the plants differ from the other species in this complex. Hence, we describe a new species named M. occidentalis morphologically similar to M. planifolia but can be distinguished from it by the oblong-ovoid corm, channeled leaves, which are papillate on both sides, perigone 1.8–2.5 cm long, funnel-shaped, yellowish and light purple striate, perigone tube 0.3–0.7 × 0.2–0.4 cm, filaments adnate to the perigone and arising 0.3–0.7 cm above the ovary apex, anthers 0.9–1.1 cm long, and style 2.1–3.5 cm long, exceeding the perigone tube by 1.8–3 cm at anthesis. Manfreda occidentalis also resembles M. chamelensis; however, phenologic asynchrony is a notable difference between them as well as the shape of the leaves and the length and shape of perigone tube and lobes. A distribution map, photographs, and a key to identify species of Manfreda which grow in western Mexico accompany the description.
