The family Trogossitidae Latreille occurs worldwide, including some Pacific islands. The family contains about 50 genera and 600 described species, and the group was recently classified by Kolibáč into three subfamilies, Lophocaterinae, Peltinae and Trogossitinae. Among the lophocaterine genera, a genus Ancyrona Reitter includes 62 species in most parts of the world except the Nearctic region, and is divided into five informal species groups by Kolibáč. In this study, the genus Ancyrona and its a single species, A. diversa (Pic), is newly reported in the Korean fauna. A diagnosis, habitus photographs, and illustrations of female diagnostic characters are provided, with a key to Palaearctic species of the genus Ancyrona.

제주도의 조하대 저 질에서 채집 한 해 양 선충류 1신종 제주곁도마뱀 선충 (Faradraconema jejuense)을 기재하였다. 제주곁도마뱀선충은 가늘고 긴 형태의 유사한 체형과 암수 모두 다 동일한 형태의 두부감각기관을 가지는 점에서 P antarcticum과 유사하지만 몸 뒤쪽 부위의 측면 아래에 수컷은 9개에서 10개, 암컷은 11개에서 12개, 배면 아래에 수컷은 16개에서 17개, 암컷은 17개에서 18개의 후미흡착기관을 가지는 점, 1쌍의 두부 돌기를 가지는 점, 안점을 가지지 않는 점, 몸 중앙 측면의 표면이 구별되는 점과 같은 중요 형질에서 쉽게 구분되어 진다. 이 논문은 한국의 곁도마뱀선충속 해양 선충류에 대한 첫 분류학적 보고이다.

Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades. Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department. Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients' habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%). Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.
