Abstract A new subgenus, Reinertia Somboon, Namgay & Harbach, of the genus Aedes Meigen and its type species, Ae. suffusus Edwards, are described from specimens reared from larvae and pupae found in a tree hole in Bhutan. The scutum of the adults is mostly covered with narrow pale falcate scales. The proboscis, maxillary palpus, tibiae, and tarsi are dark-scaled. The gonocoxite of the male genitalia bears a unique setose basomesal sclerite. The larva closely resembles larvae of the subgenus Downsiomyia Vargus in having setae 4–6-C with numerous branches and inserted more or less on level with seta 7-C, abdominal seta 12-I is present and the comb is composed of 6–10 spine-like scales arranged in an irregular row. Surprisingly, Reinertia shares features of the adult habitus, male genitalia, and larva with the Palearctic subgenus Dahliana Reinert, Harbach & Kitching. However, in phylogenetic analyses of the mitochondrial COI gene of species representing 38 subgenera of Aedes and six other genera of the tribe Aedini Neveu-Lemaire, Reinertia was not associated with Dahliana or Downsiomyia. In both maximum likelihood and Bayesian analyses of the data, Ae. suffusus was recovered as the weakly supported sister of a clade composed of five species of the subgenus Protomacleaya Theobald. In the absence of strong support, and because Protomacleaya is an unnatural group of species that resemble each other phenetically by virtue of what they lack, Ae. suffusus cannot be placed in the subgenus Protomacleaya. Thus, the morphological and molecular data attest the uniqueness of Ae. suffusus and its recognition as a monobasic subgeneric lineage.

A New Species

We described a new cossid species, Dyspessa ulgen sp. nov. from the Tarbagatai and Altai Mountains and compared it to other taxa of Dyspessa reported from the region (D. tristis, D. saldaitisi, D. saissanica), as well as to morphologically similar D. ulula. The new species is most closely related to D. ulula but differs from the latter in the characteristics of the male genitalia, wing pattern, and molecular data (a 658 bp fragment of the mitochondrial COI gene).

The lack of university funding is one of the major impediments to taxonomy, partly because traditional taxonomic training takes longer than a PhD course. Understanding ranges of phenotypic variability for different morphological structures, and their use as characters for delimitation and description of taxa, is a tedious task. We argue that the advent of molecular barcoding and quantitative shape analysis makes it unnecessary. As an example, we tackle a problematic species-complex of marine copepods from Korea and Japan, approaching it as a starting taxonomist might. Samples were collected from 14 locations and the mitochondrial COI gene was sequenced from 42 specimens. Our phylogenetic analyses reveal four distinct clades in Korea and Japan, and an additional nine belonging to a closely related complex from other parts of the Northern Pacific. Twenty different morphological structures were analysed for one Japanese and two Korean clades using landmark-based two-dimensional geometric morphometrics. Although there is no single morphological character that can distinguish with absolute certainty all three cryptic species, most show statistically significant interspecific differences in shape and size. We use five characters to describe two new species from Korea and to re-describe Tigriopus japonicus Mori, 1938 from near its type locality.

Abstract. Md-Zain BM, Mohhoyua KS, Aifat NR, Ngadi E, Ayob N, Rovie-Ryan JJ, Ampeng A, Mohd-Ridwan AR, Blair ME, Abdul-Latiff MAB. 2019. Molecular data confirm the presence of Nycticebus bengalensis on Langkawi Island, Malaysia. Biodiversitas 20: 1115-1120. Recent taxonomic reviews have stated the possibility of Bengal Slow Loris (Nycticebus bengalensis) presence in the Northern part of the Malay Peninsula. This study aims to confirm the presence of the Bengal Slow Loris in Malaysia by sequencing the mitochondrial COI gene from samples collected from Langkawi Island, Peninsular Malaysia, and Borneo. Phylogenetic analyses produced tree topologies that support the grouping of slow loris samples by their localities. The tree topologies further show that slow loris samples from Sarawak and Peninsular Malaysia form two distinct clades. The clade from Peninsular Malaysia was divided into two subclades, Langkawi and Selangor. The Langkawi slow loris subclade includes sequences from GenBank representing N. bengalensis, supported by a high bootstrap value. This mitochondrial DNA finding has a significant contribution to indicate the presence of the Bengal Slow Loris in Malaysia.

Degree Of Similarity

Study of morphological characters of Tetranychus macfarlanei Baker & Pritchard and Tetranychus malaysiensis Ehara revealed high similarity by comparing all the important characters in addition to the characters pointed out by Ehara to separate those two species. Molecular phylogeny of seven Indian populations of T. macfarlanei and one population of T. malaysiensis from Philippines along with few distantly related species of Tetranychus was attempted. High degree of similarity between these two species at mitochondrial COI gene (96%) as well as ITS2 (rDNA) (96–99%) region was evident. Based on both morphological features and molecular data, T. malaysiensis is proposed as a junior synonym of T. macfarlanei based on ICZN’s law of priority. Also more female characters are prompted in this study to distinctly discriminate T. macfarlanei from its most resembling species, Tetranychus ludeni Zacher. Tetranychus macfarlanei has emerged as a pest of several cultivated crop plants in India.

A New Species

A new species of the Cyrtodactylus irregularis group is described from Ninh Thuan Province, southern Vietnam based on molecular divergence and morphological differences. Cyrtodactylus orlovi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by having the unique combination of the following characters: size medium (SVL 61.0–77.7 mm); dorsal tubercles in 16–20 irregular rows; 36–39 ventral scale rows; precloacal pores absent in females, 5 or 6 in males, in a continuous row; femoral pores absent; 3–8 enlarged femoral scales; postcloacal spurs 1 or 2; lamellae under toe IV 16–19; a continuous neckband; a highly irregular transverse banded dorsal pattern; the absence of transversely enlarged median subcaudal scales. In phylogenetic analyses, the new species was revealed to be the sister taxon to a clade consisting of Cyrtodactylus cattienensis and the most recently described species from Vietnam, C. chungi, with 12.1–12.4% and 11.7 % pairwise genetic divergence from the two species, respectively, based on a fragment of the mitochondrial COI gene.

Molecular Characters

A new poroid wood-inhabiting fungal species, Atraporiella yunnanensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by cream pore surface when dry, which is easy to separate from substrate and very rapidly stained dark brown to black when bruised; hyphal system monomitic with generative hyphae hyaline to pale brown, thin-walled, unbranched, interwoven; slightly allantoid basidiospores, 2.2–3 × 0.8–1.5 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that Atraporiella yunnanensis belonged to the residual polyporoid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to A. neotropica, and then grouped with other related genera: Antrodiella, Pouzaroporia, Steccherinum and Xanthoporus. Both morphological and molecular characters confirmed the placement of the new species in Atraporiella.

Grammatuslabyrinthinusgen. et sp. nov. is proposed based on DNA sequences data and morphological characteristics. It is known so far from southern, tropical China. The new species is characterised by an annual, resupinate basidiocarp with a shallow, subporoid hymenophore, a hymenium restricted to the bottom of the tubes, a dimitic hyphal system, presence of encrusted skeletocystidia and dendrohyphidia, longitudinally septate basidia and smooth, oblong-ellipsoid to cylindrical, acyanophilous basidiospores. Phylogenetic analyses based on ITS + nLSU DNA sequences data indicate that G.labyrinthinus belongs to Auriculariaceae in which it has an isolated position. Phylogenetic inferences show G.labyrinthinus to be related to Heteroradulum. However, the ITS sequences similarity between G.labyrinthinus and H.kmetii, the type species of Heteroradulum, were 89.84% and support the establishment of the new genus. Inversely, Heteroradulumsemis clustered with G.labyrinthinus with strong support and it is transferred to Grammatus.

Morphological Differences

Recent molecular phylogenetic analyses of scleractinian corals have resulted in the discovery of cryptic lineages. To understand species diversity in corals, these lineages need to be taxonomically defined. In the present study, we report the discovery of a distinct lineage obscured by the traditional morphological variation of Fungia fungites. This taxon exists as two distinct morphs: attached and unattached. Molecular phylogenetic analyses using mitochondrial COI and nuclear ITS markers as well as morphological comparisons were performed to clarify their phylogenetic relationships and taxonomic positions. Molecular data revealed that F. fungites consists of two genetically distinct clades (A and B). Clade A is sister to a lineage including Danafungia scruposa and Halomitra pileus, while clade B formed an independent lineage genetically distant from these three species. The two morphs were also found to be included in both clades, although the attached morph was predominantly found in clade A. Morphologically, both clades were statistically different in density of septal dentation, septal number, and septal teeth shape. These results indicate that F. fungites as presently recognized is actually a species complex including at least two species. After checking type specimens, we conclude that specimens in clade A represent true F. fungites with two morphs (unattached and attached) and that all of those in clade B represent an unknown species and genus comprising an unattached morph with only one exception. These findings suggest that more unrecognized taxa with hitherto unnoticed morphological differences can be present among scleractinian corals.

The Ulopinae leafhopper genera of the tribe Ulopini from the Indian subcontinent (Daimachus Distant and Radhades Distant) are redescribed. Four new species of Daimachus are described: D. matheranensis sp. nov. (India: Maharashtra), D. robustus sp. nov. (India: Kerala), D. sirsiensis sp. nov. (India: Karnataka) and D. sudindicus sp. nov. (India: Karnataka, Kerala). Ulopa brunnea Pruthi 1930 is treated as a junior synonym of Daimachus exemplificatus Distant 1916 based on a study of the male genitalia of both species. The latter species, together with Radhades crassus Distant and Ulopsina Dai, Viraktamath & Zhang are redescribed and a new subgenus of Ulopsina, Indoulopa subgen. nov. is described from Sub-Himalayan region with Ulopsina (Indoulopa) himalayana sp. nov. as the type species; the genus is reported for the first time from the subcontinent. Key to genera and species dealt with are also provided, all taxa are illustrated and lectotypes are designated for Daimachus exemplificatus, Ulopa brunnea and Radhades crassus.

Morphological And Molecular Data

We present a revision of the Neotropical bat genus Chiroderma, commonly known as big-eyed bats. Although species of Chiroderma have a wide distribution from western México to southern Brazil, species limits within Chiroderma are not clearly defined, as attested by identification errors in the literature, and there is no comprehensive revision of the genus that includes morphological and molecular data. Our review is based on phylogenetic analyses of two mitochondrial (COI and CYTB) and two nuclear (RAG2 and DBY) genes, coalescence analyses of mitochondrial genes, and morphological analyses including type specimens of all named taxa. We recognize seven species in three clades: the first clade includes (1) C. scopaeum Handley, 1966, endemic to western México and previously considered a subspecies of C. salvini; and (2) C. salvini Dobson, 1878, a taxon associated with montane forests, distributed from México to Bolivia; the second clade includes (3) C. improvisum Baker and Genoways, 1976, endemic to the Lesser Antilles, and (4) C. villosum Peters, 1860, widely distributed on the continental mainland and polytypic, with subspecies C. v. villosum and C. v. jesupi; and the third clade includes (5) the polytypic C. doriae Thomas, 1891, with C. d. doriae distributed in eastern Brazil and Paraguay, and C. d. vizottoi, occurring in northeastern Brazil; (6) C. trinitatum Goodwin, 1958, distributed from Trinidad to Amazonia; and (7) C. gorgasi Handley, 1960, distributed from Honduras to trans-Andean South America, previously considered a subspecies of C. trinitatum.
