Yara Reichardt and Hinton

Differential Diagnosis. Dorsum covered with dense, short setae ( Fig. 1 ). Antenna 8-segmented as in Hydroscapha ( Fig. 2 ; as opposed to 5 segments in Scaphydra ). Mentum and submentum not fused ( Fig. 4B ). Metacoxa with femoral plate short, reduced to area of articulation with metatrochanter ( Fig. 4A ). Metatrochanters with row of stiff, spine-like setae ( Fig. 4A ; absent in Hydroscapha and Scaphydra ). Abdomen with tergite IV ( Fig. 4B ) lacking a dense covering of setae (present in Hydroscapha and Scaphydra ). Aedeagus consisting of a forked base with a long, uncoiled median lobe ( Fig. 6).

have been used. In others, the term “last sternite” or “last ventrite” is used in place of the actual segment number. This can lead to substantial confusion as the males and females of the present species actually have a differing number of exposed abdominal segments, thus the “last sternite” is VIII in the females and XI in the male!
