Euphalacra nigridorsoides sp. n.  

Euphalacra nigridorsoides

12mm. In facies this species is very similar to nigridorsata Warren (15-20mm) but is smaller. The rather crenulate, rich brown fasciation is intensified obliquely postmedially on the forewing and is contiguous at the dorsum with a dark subbasal fascia on the hindwing. The hindwing margin is rounded rather than apically excavate and its postmedial fascia is angled centrally rather than at one quarter from the costa. Despite the similarity in facies to nigridorsata the male genitalia are very different, with the socii slender, forked, and a rugose gnathus present. The valves have a single basal process with setae. The aedeagus has a haken-like structure apically (See Thyatirinae) and two smaller spines associated with it.
