The endangered butterfly Scada karschina delicata Talbot, 1932 (Nymphalidae: Danainae: Ithomiini) is endemic to northeastern Brazil, occurring in very few forest remnants of the ‘Pernambuco Center of Endemism’. Larvae feed on Solanaceae and are very similar to those of other species in the subtribe Mechanitina, with lateral projections on body, one of the main synapomorphies of this subtribe. Based on molecular data, S. k. delicata clustered together with S. karschina karschina, as a monophyletic group sister to the amazon clade of S. reckia. Based on all available data, S. k. delicata is known from only five localities of mid- to high-altitude forests (from 500 to 1000 m of altitude) in northeastern Brazil. Grounded on available data, a new assessment of extinction risk is proposed, and S. k. delicata is now considered Vulnerable (VU) taxon.

濒临灭绝的蝴蝶Scada karschina delicata Talbot，1932年（Nymphalidae：Danainae：Ithomiini）是巴西东北部特有的动物，仅在“伯南布哥地方性中心”的少量森林残留物中出现。幼虫以茄科为食，与机械亚科中的其他物种非常相似，其体侧向突出，是该亚科的主要同形亚种。根据分子数据，S.k。delicata群集连同S. karschina karschina，作为一个单系类群妹妹的亚马逊进化枝S. reckia。根据所有可用数据，S.k。美味仅在巴西东北部的五个中高海拔森林地区（海拔500至1000 m）就可以知道。在现有数据的基础上，提出了一种新的灭绝风险评估方法，S。k 。现在，delicata被认为是脆弱（VU）分类单元。
