Two halacarid mites viz. Copidognathus australensis (Lohmann, 1909), and Rhombognathus validipes Bartsch, 2000 are reported from India for the first time. Copidognathus australensis was collected from Chatham Island (Andaman Islands) and Rhombognathus validipes was collected from Wandoor, South Andaman (Andaman Islands) and Mus Island (Nicobar Islands). Earlier records of these species were from Australia.

Copidognathus australensis odnotowano na wyspie Chatham Island (Andamany), a Rhombognathus validipes został zebrany na wyspach: Wandoor (Północny Andaman) i Mus Island (Nicobar). W cześniejsze informacje o występowaniu tych gatunków były podawane z Australii.

An updated overview of sexual dimorphism in halacarid mites is presented in this paper. Males and females of halacarid mites morphologically differ in the genital region. Additionally, sexual dimorphism can be seen in some species in dorsal plates, ventral plates, chaetotaxy of legs, idiosoma, gnathosoma, which is the theme of the present paper. A distinction of males vs. female mites is someti - mes reflected in size and fusion of various idiosomal plates and width of cuticular membranous areas. Other sexually dimorphic characters such as paragenital are - olae, postgenital papillae, lamella in legs, fossary setae on tarsus found in some species of halacarids are also discussed
PL
W artykule zaprezentowano przegląd obecnego stanu wiedzy na temat dymorfizmu płcio - wego u Halacaridae. Samice i samce Halacaridae przede wszystkim różnią się morfologią rejonu genitalnego. Dodatkowo dymorfizm płciowy zaznacza się u niektórych gatunków w wyglądzie tarcz grzbietowych, tarcz brzusznych, chemotaksji odnóży krocznych oraz ogólnym kształtem idiosomy i gnatosomy. Odmienność samców i samic może czasami przejawiać się rozmiarach tarcz idiosomalnych, ich łączeniu się oraz szerokościach mięk - kich, kutykularnych odstępów pomiędzy tarczami. W pracy omówiono również inne róż - nice płciowe: przyssawki genitalne, płytki na nogach, zagłębione szczeciny na stopach

The present study reports a new distribution record for the halacarid mite Acarothrix palustris Bartsch, 1990 on mangrove pneumatophores from Goa, India. Earlier this species was known from Hong Kong and Singapore (West Pacific Ocean). The present report represents the first record of the species from the Indian Ocean.

Two new species of the superfamily Oripodoidea, Maculobates bruneiensis sp. nov. and Perscheloribates interlamellaris sp. nov., are described from Brunei. The first new species differs from other species of Maculobates by the presence of an anterior notogastral margin and a specific furrow on ventral side. The second new species differs from other species of Perscheloribates by the microfoveolate body surface. The genera Maculobates and Perscheloribates are for the first time recorded in Brunei; Maculobates is for the first time recorded in the Oriental region.

Seven epibiotic halacarid mites (Caspihalacarus hyrcanus, two species of Copidognathus, Halacarellus petiti, Porohalacarus alpinus, Soldanellonyx monardi and S. chappuisi), two oribatid mites (Hydrozetes lacustris and Trhypochthoniellus longisetus) and one water mite (Piona pusilla) were found on the setae-covered claws of eighteen Chinese mitten crabs (Eriocheir sinensis) collected from fresh and brackish waters in Poland and Germany. The most abundant of the 111 mite individuals recorded was one of the Copidognathus species (N = 52); this was followed by H. petiti (N = 38) and C. hyrcanus (N = 13). This is the first record of H. petiti and of the genus Copidognathus from Polish waters. The possibility of migrating over long distances assisted by catadromous mitten crabs enhances mite dispersal, as well as their introduction to new environments.

Rhizome extracts of Hedychium coronarium are widely used as phytotherapeutics. As of date, there is no documented study on the standardization of H. coronarium extract, and the following research is an effort in this direction. Coronarin D is an important bioactive compound present in H. coronarium which shows chemopreventive activity against cancer. H. coronarium extracts were assessed for coronarin D content for the first time. The extraction was checked using different solvents: n-hexane, acetone, and methanol. Coronarin D was separated on silica gel 60F254 high-performance thin-layer chromatography (HPTLC) plates by isocratic gradient method using n-hexane-ethyl acetate (80:20 v/v) as mobile phase. Densitometric quantification was performed at 231 nm in absorption mode. This method gave a well-defined peak at Rf 0.20 corresponding to coronarin D. The method was validated using International Conference on Harmonization (ICH) guidelines in terms of precision, repeatability, and accuracy. Linearity range of coronarin D was 200–1000 ng spot−1 with a correlation coefficient of R2 ± SD = 0.9987 ± 2.62% in the concentration range of 200–1000 ng spot−1. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 35 and 115 ng, respectively. Accuracy of the method was checked by recovery studies conducted at three different concentration levels, and the average percentage recovery was found to be 98.22 % for coronarin D. Among the different solvents, acetone produced maximum extraction efficiency of coronarin D. The proposed HPTLC method can be applied for robust identification and quantitative determination of coronarin D in H. coronarium extracts.
