  • In this study, three lecanid rotifer species were newly recorded in Korea: Lecane inermis (Bryce, 1892), L. furcata (Murray, 1913), and L. nana (Murray, 1913). Most of the lecanid rotifers recorded in Korea have been collected from stagnant water, and Lecane furcata and L. nana were collected from a reservoir. In contrast, L. inermis was found in a soil sample. Lecane inermis is the first illoricated lecanid species reported in Korea. This species is distinguished from other illoricated species by its toes with relatively long claws. Lecane furcata is the most common lecanid rotifer in submerged vegetation. The morphological characteristics of its lorica are similar to many other lecanid rotifers, but it can be distinguished by its completely fused toes with a terminal fissure, an absence of antero-lateral spines, and the ratio of lorica/toe length. Lecane nana is most similar to L. tryphema Harring & Myers, 1926, but can be distinguished by the toe tips curved outwards. The three species in this study are considered to have a cosmopolitan distribution and have been recorded in many Asian countries. In this paper, we describe the morphological characteristics of the three lecanid species with trophi structures observed by scanning electron microscope.

  • In the present study, hybrid vigour in terms of heterosis and over dominance of newly evolved bivoltine hybrids and their reciprocals raised from the promising newly evolved bivoltine breeds were calculated for the important parameters like pupation, cocoon yield, cocoon weight, shell weight, shell ratio, raw silk percentage, filament length and neatness. Through there was no significant difference among the hybrids for the characters pupation, cocoon yield and cocoon weight, the magnitude of heterosis and over dominance were varied significantly for these characters. However, significant differences were observed between new hybrids and control hybrid for the characters like cocoon shell weight, cocoon shell ratio, filament length and raw silk percentage. The results indicate that majority of new hybrids have shown higher heterosis and over dominance than control hybrid. The data also indicate that highest mean heterosis of all new hybrids was recorded for cocoon yield followed by filament length. Whereas highest mean over dominance was recorded for cocoon yield followed by cocoon weight. Negative mean heterosis and over dominance were recorded for the trait cocoon shell ratio. Based on the results, the importance of three hybrids viz., CSR2 ${\times}$ CSR4, CSR2 ${\times}$ CSR5 and CSR3 ${\times}$ CSR6 and their reciprocals (CSR4 ${\times}$ CSR2, CSR5 ${\times}$ CSR2 and CSR6 ${\times}$ CSR3) which exhibited significant heterosis and over dominance, for commercial exploitation was discussed.

  • Two newly recorded small orb weavers, Araneus yasudai Tanikawa, 2001 and Neoscona flavida sp. nov., with characteristic epigynal scape belonging to Araneidae are described with measurements and morphological illustrations from Korea. Both species were collected with sweep net between shrubs and bushes in mountain forest and between reeds in reclaimed land, respectively.

  • Newly recorded cyproideid species of the genus Terepeltopes was collected from Korean waters. The monotyptic genus Terepeltopes erected with T. dolichorhunia Hirayama, 1983 was only known to be found at West Kyushu, Japan. In this study, the family Cyproideidae Barnard, 1974 is first recorded from Korea by the discovery of T. dolichorhunia, and we provide description and illustrations of this species.

  • A newly recorded species Orientomaera incisa Ariyama, 2020, belonging to the family Maeridae Krapp-Schickel, 2008, was collected from the sublittoral waters of the East Sea, Korea. Previously, only one species, O. brevispina (Kim and Kim, 1991), was reported in Korea. This species morphologically similar to O. brevispina however, the species can be easily distinguished from the O. brevispina by having two distinct teeth on palm of gnathopod 2. The newly recorded species is described and fully illustrated in the present study.
