Sucinorhagonycha maryae PANKOWSKI & Fanti 2023, sp. nov.

Sucinorhagonycha maryae sp. nov. (Fig. 1) Holotype. Female, inclusion in Baltic amber, housed at the Smithsonian National Museum of Natural History, USNM PAL 787823. Syninclusions: Air bubbles and debris. Etymology. Species named in honor of Mary K. Pankowski, the first author’s elder sister and trusted advisor. Diagnosis. The specimen clearly belongs to the genus Sucinorhagonycha based on its securiform last maxillary palpomere, long elytra, filiform and 12-segmented antennae, the pronotum without lobes at the sides, and the simple claws without lobes and denticles. Based on its transverse pronotum, the new species described here is most similar to S. kulickae Kuśka, 1996, but it differs from the latter species in the length of the antennomeres; in particular, the antennomere V of the new species is long and distinctly longer than III, while it is very short and as long as the third in S. kulickae. The new species is also significantly larger than the holotype of S. kulickae, which is only 4.5 mm in length (Kuśka, 1996; Fanti & Pankowski, 2018; Kazantsev, 2020). Kubisz (2000) describes the female of S. kulickae; however, given the enormous difference with the holotype (a male), we are convinced that it is a different species. Locality and horizon.
