A New Species

We studied the quill mite fauna of the family Syringophilidae, associated with bee-eaters. We examined 273 bird specimens belonging to nine closely related species of the genus Merops, representing two phylogenetic sister clades of a monophyletic group. Our examination reveals the presence of two species of the genus Peristerophila, as follows: (1) a new species Peristerophila mayri sp. n. from Merops viridis in the Philippines, M. leschenaulti in Nepal and Sri Lanka, and M. orientalis in Sri Lanka; and (2) P. meropis from M. superciliosus in Tanzania and Egypt, M. persicus in Sudan, Tanzania, Liberia, Senegal, Kenya, and D.R. Congo, M. ornatus in Papua New Guinea, M. philippinus in Thailand, Indonesia and Sri Lanka, and M. americanus in the Philippines. The prevalence of host infestations by syringophilid mites varied from 3.1 to 38.2%. The distribution of syringophilid mites corresponds with the sister clade phylogenetic relationships of the hosts, except for P. meropis associated with Merops americanus. Possible hypotheses for the host lineage shift are proposed.

A New Species

AbstractParmeliella zeylanica is described as a new species in the P. mariana group, although it differs from all known species in the group by not having radiating marginal lobes resting on a distinct mat of rhizohyphae. It is as yet known only from the highlands of Sri Lanka. The new combination Parmeliella leiostroma (Nyl.) P. M. Jørg. is made for a closely related species from the same region, and it is shown that Parmeliella endomilta var. achromatica Makhija & Adawara falls within the variation of Parmeliella mariana (Fr.) P. M.Jørg. & D. J. Galloway, and is not closely related to P. endomilta.

Abstract A new species of Nessia is described from Sri Lanka. Nessia gansi sp. n. is distinguished from its sister species (N. burtonii) based on the morphological and meristic data. The new species differs from all other congeners except N. burtonii Gray, by a combination of following characters: presence of four limbs; all limbs bearing three digits; interparietal broader than frontal. It distinguishes from N. burtonii by having five (vs. six) supraciliaries; one (vs. two) pretemporal/s; two (vs. one) primary temporal/s; three (vs. four) infralabials; 93-105 (vs. 110-124) paravertebral scale rows; 103-114 (vs. 117-121) ventral scales; two (vs. three) subdigital lamellae under each digit of manus; mental as wide as postmental (vs. mental wider than postmental); and nostrils visible when viewed ventrally (vs. not visible). Two closely related species show a discrete distribution in Sri Lanka: N. gansi sp. n. is recorded from Kanneliya, Rumaswala, Kottawa, Panagula, Ambalangoda and Imaduwa in the first and second peneplains (~100 m), whereas N. burtonii records (here corrected) are reported from Alagalla, Ambagamuwa, Gampola, Hiniduma and Kandy within the third peneplain (from ~500 m). The identity of N. burtonii is stabilized through the designation of a neotype, and here it is re-described.

Based on the study of the type series and material from Sri Lanka, a comprehensive description of Chydorus ventricosus Daday is given including the first description of the male. The detailed morphology of all instars of females and males, population structure, and some biological notes are also provided. This species was considered a tropicopolitan species based on previous records from Asia, America, and Africa. However, a detailed study of populations from a wide area of the Oriental region and material previously designated as Chydorus ventricosus from America and Africa, and a critical review of the literature indicates that it is very probably restricted to the Oriental region. Chydorus ventricosus closely resembles an undetermined number of taxa. Only a detailed study will determine their status. We have compared it with the only two well-described, closely related species. The present study has characterized all stages of Chydorus ventricosus. This will enable accurate diagnosis of this species.

Genome Amplification

Finger millet is a superior staple food for human beings. Microsatellite or Simple Sequence Repeat (SSR) marker is a powerful tool for genetic mapping, diversity analysis and plant breeding. In finger millet, microsatellites show a higher level of polymorphism than other molecular marker systems. The identification and development of microsatellite markers are extremely expensive and time-consuming. Only less than 50% of SSR markers have been developed from microsatellite sequences for finger millet. Therefore, it is important to transfer SSR markers developed for related species/genus to finger millet. Cross-genome transferability is the easiest and cheapest method to develop SSR markers. Many comparative mapping studies using microsatellite markers clearly revealed the presence of synteny within the genomes of closely related species/ genus. Sufficient homology exists among several crop plant genomes in the sequences flanking the SSR loci. Thus, the SSR markers are beneficial to amplify the target regions in the finger millet genome. Many SSR markers were used for the analysis of cross-genome amplification in various plants such as Setaria italica, Pennisetum glaucum, Oryza sativa, Triticum aestivum, Zea mays and Hordeum vulgare. However, there is very little information available about cross-genome amplification of these markers in finger millet. The only limited report is available for the utilization of cross-genome amplified microsatellite markers in genetic analysis, gene mapping and other applications in finger millet. This review highlights the importance and implication of microsatellite markers such as genomic SSR (gSSR) and Expressed Sequence Tag (EST)-SSR in cross-genome analysis in finger millet. Nowadays, crop improvement has been one of the major priority areas of research in agriculture. The genome assisted breeding and genetic engineering plays a very crucial role in enhancing crop productivity. The rapid advance in molecular marker technology is helpful for crop improvement. Therefore, this review will be very helpful to the researchers for understanding the importance and implication of SSR markers in closely related species.
