A new genus and species of freshwater crab, Melothelphusa apiaka n. gen., n. sp., from Mato Grosso, Central Brazil is described and illustrated. Brasiliothelphusa dardanelosensis Magalhães & Türkay, 2010, is assigned to the new genus Melothelphusa. Therefore, the genus Brasiliothelphusa Magalhães & Türkay, 1986, is restricted to its type species B. tapajoense Magalhães & Türkay, 1986. The new taxa can be easily separated from their close relatives by a suite of morphological characters from the first gonopod.
描述并图示了一种来自巴西中部马托格罗索州的淡水蟹新属新种——阿皮亚卡美洛束腹蟹(Melothelphusa apiaka n. gen., n. sp.)。2010年的达达内洛斯巴西束腹蟹(Brasiliothelphusa dardanelosensis Magalhães & Türkay)被归入新属美洛束腹蟹属(Melothelphusa)。因此,1986年的巴西束腹蟹属(Brasiliothelphusa Magalhães & Türkay)被限定为其模式种——1986年的塔帕若斯巴西束腹蟹(B. tapajoense Magalhães & Türkay)。通过第一对交接器的一系列形态特征,这些新分类单元可以很容易地与其近缘种区分开来。
