The new, small cavernicolous species Helmablatta louisrothi gen. et sp. n. (Nocticolidae) from the Tan-Phu cave (Vietnam) is one of the most morphologically interesting cockroaches. The extremely modified upstanding tergal gland composite from three tergites and may serve for gripping the female head during copulation. This presumption is supported by the presence of a central big hook on tergite 8. Furthermore, both wing pairs are uncommonly adapted to help releasing sex pheromones without raising the wings. Histone 3 DNA-based maximum likelihood analyses indicate a recent origin and close phylogenetic relationship between Nocticola spp. and Helmablatta sp.-consistent with the Quaternary age of the source lava tubes.
来自越南潭富洞穴的新的小型洞穴蟑螂物种Helmablatta louisrothi gen. et sp. n.（夜隐蜚蠊科）是形态上最有趣的蟑螂之一。由三个背板极度特化形成的直立背板腺复合体，可能在交配时用于抓住雌虫头部。背板8上存在一个中央大钩支持了这一推测。此外，两对翅膀都有不同寻常的适应性，有助于在不抬起翅膀的情况下释放性信息素。基于组蛋白3 DNA的最大似然分析表明，夜隐蜚蠊属物种和Helmablatta属物种起源较近且系统发育关系密切，这与源熔岩管的第四纪年龄一致。
