General description. Body rather robust, heavily pubescent, pronotum entirely rugose; no lateral carinae, rounded in sections; sulcus just behind the end of 2nd 1/3rd of total length; median carina not detectable on all specimens. Fastigium short, subtrapezoidal; eyes prominent in male, scarcely in female. Tegmina lateral, elliptical; densely reticulated, not reaching the midway point of 1 st abdominal tergite in males and the 2nd abdominal tergite in females. Fore and middle femora moderately swollen in male, lower margin of hind femur bright red. External male terminalia: furculae vestigial or absent, supra-anal plate subtriangular, cerci wider at base and narrowed at apex with apical portion curved inwards midway to varying degrees within different species. Subgenital plate hemiconical, short, pointed to varying degrees at apex. Internal male genitalia: epiphallus well-sclerotized with ancorae bent slightly ventrally as well as inwards to varying degrees, lophi prominent and subrectangular in addition to bending anteriorly to some degree. Ectophallus with prominent rami and fairly elaborate sheath of aedeagus. Endophallus with relatively short valves of aedeagus that are not especially complex compared to other melanoplines. External female terminalia: supra-anal plate subtriangular, cerci relatively small and subconical, and dorsal valves of ovipositor with teeth along majority of dorsal margin.
Discussion. In determining the systematic position of the genus Liladownsia (Woller et al., 2014), we examined related genera of Dactylotini and by examining our material of Dasyscirtus we found a specimen not belonging to either of the two known species of the genus: D. olivaceus and D. hirsutus. We then managed to find more specimens in the ANSP with labels indicating the possibility of being a new species. The genus has been extensively described from the male in the original description of Bruner (1908). Therefore, here, we summarize only the main characters of males (Table 2), with a detailed update of the terminalia descriptions, and add some details of female morphology.
