Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, sp. nov. and sp. nov., and a new, morphologically remarkable population of Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.
侏罗甲科是一类幼态化的叩头虫类甲虫，最近基于两个属的三个物种从巴西大西洋森林生物多样性热点地区被描述出来。该科所有生命阶段都生活在土壤中，包括幼态雌虫，只有成年雄虫能够飞行。在此，我们报告发现了两个新物种，即[新物种1学名]和[新物种2学名]，以及一个形态上显著的新种群，即罗莎等人于2020年描述的[种群学名]。我们的发现进一步揭示了该类群的多样性和生物地理学。侏罗甲科的大多数物种见于大西洋森林的雨林残余地，但在此我们首次报告了一种来自相对干燥的大西洋森林/卡廷加过渡带的侏罗甲科物种。鉴于我们最近的发现，所有侏罗甲科昆虫体型微小且生活隐秘，再加上大西洋森林以及可能其他周边生态区域可能存在大量尚未描述的该科物种，我们呼吁在潜在适宜地区开展实地研究，并对存放在巴西多个研究所、实验室和收藏机构的大量已收集但仍未处理的材料进行详细调查。
