Evolutionary Consequences

Natural hybridization is rather widespread and common in animals and can have important evolutionary consequences. In terms of taxonomy, exploring hybridization and introgression is crucial in defining species boundaries and testing taxonomic hypotheses. In the present paper, we report on natural hybrid specimens between Ahlbergia frivaldszkyi (Lederer, 1853) and Callophrys rubi (Linnaeus, 1758). To test the hypothesis of their hybrid origin, we employed the molecular mitochondrial (COI gene) and nuclear (wingless, RPS5, and Ca-ATPase genes) markers commonly used in phylogenetic studies and explored the morphology of the specimens. Our analysis revealed that hybrids bear mitochondrial haplotypes of C. rubi, while nuclear fragments are heterozygous, sharing a combination of A. frivaldszkyi and C. rubi lineages. The hybrid specimens combine morphological characters of both genera. Our results for the first time empirically demonstrate the possibility of genetic introgression between these species and between the genera Callophrys and Ahlbergia on the whole.

Are Tetranychus macfarlanei Baker & Pritchard and Tetranychus malaysiensis Ehara (Acari: Tetranychidae) one species? Morphological and molecular evidences for synonymy between these two spider mite species and a note on invasiveness of T. macfarlanei on okra and eggplant in India

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, Maua squeala sp. nov., is described from China. This species is similar to M. affinis Distant, 1905 and M. palawanensis Duffels, 2009, but can be distinguished by the shorter and more slender body of the new species, the lateral fasciae on the mesonotum and the shape of the male genitalia. The intraspecific variation of this species is discussed based on morphological observation combined with sequences of partial mitochondrial COI gene (DNA barcoding) of individuals exhibiting different morphological characters.

Mitochondrial Coi Gene

A molecular taxonomy is presented based on 544 base pair sequences of the mitochondrial COI gene (Palumbi segment) from 141 bristle crabs of the genus Pilumnus from the Mediterranean Sea and adjacent Atlantic Ocean, plus outgroups. The sample includes all currently valid autochthonous Mediterranean species. Six well-supported COI lineages were detected, three of which exclusively comprise representatives of Pilumnus inermis, P. spinifer and P. villosissimus, respectively. On the other hand, crabs that would be attributed to P. hirtellus according to current morphology-based taxonomy were distributed over three COI clades, two of which are interpreted as representing cryptic lineages. We compare our findings to previous analyses using sets of external morphological characters, and discuss the partial mismatch between the morphology- and gene-based classifications.

Genetic Distinctiveness

Ten species, including four new species, of the chewing louse genus Forficuloecus Conci, 1941, are recognized from Australasian parrots, and a key is given for their identification. The new species and their type hosts are: F. cameroni ex the Red-winged Parrot, Aprosmictus erythropterus (J.F. Gmelin, 1788); F. banksi ex the Mulga Parrot, Psephotus varius Clark, 1910; F. wilsoni ex the Northern Rosella, Platycercus venustus (Kuhl, 1820); and F. josephi ex the Bourke's Parrot, Neopsephotus bourkii (Gould, 1841). Partial sequences of the mitochondrial COI gene support the genetic distinctiveness of these new species.

Nuclear Marker

Natural hybridization was assumed to play a significant role in the diversification of Rosa. Rosa lichiangensis was suspected to be of hybrid origin based on its intermediate morphological characters between R. soulieana and R. multiflora var. cathayensis. In this study, four chloroplast regions (ndhC-trnV, ndhF-rpl32, ndhJ-trnF, and psbJ-petA) and a single copy nuclear marker (GAPDH) were used to test the hybrid origin of R. lichiangensis. The results from molecular data supported the hybrid origin of R. lichiangensis and further identified R. soulieana as its maternal progenitor and R. multiflora var. cathayensis as the paternal progenitor.

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.
