  • Fibiger (2011) established the genus Sternitta in the Micronoctuidae, with Sternitta gregerseni Fibiger, 2011 from Nepal as the type species. The Micronoctuidae are currently treated as a tribe (Micronoctuini) within the Hypenodinae, and include over 400 described species. To date, the genus Sternitta (Micronoctuini: Micronoctuina) consists of seven species: S. goateri Fibiger, 2011 in Afghanistan; S. hackeri Fibiger, 2011 and S. gabori Fibiger, 2011 in Pakistan; S. parasuffuscalis Fibiger, 2011, S. suffuscalis (Swinhoe, 1886), S. gabori Fibiger, 2011 and S. magna Fibiger, 2011 in India; S. suffuscalis (Swinhoe, 1886) in Sri Lanka and S. gregerseni Fibiger, 2011 only in Nepal (Swinhoe 1886; Fibiger 2011). The genus Sternitta was considered by Fibiger to be among the more primitive micronoctuine genera, and it can be recognized by the sclerotized 8th abdominal sternite with prominent dorsal and ventral processes and, in the male genitalia of most species, by the divided ampulla into dorsal and ventral plates and by the dorsal spinelike processes on the anellus. In the present paper, the new species Sternitta mondulkiriensis sp. n. is described from Cambodia with habitus and male genitalia illustrated and compared with those of S. suffuscalis (Swinhoe, 1886). An updated checklist and a key to all the species are included.
  • Fibiger (2011) provides both a general diagnosis and a differential diagnosis of Sternitta. In the differential diagnosis of Sternitta, Fibiger (2011: 102-103), listed features of both the wing and terminalia, including the divided ampulla, uniquely configured juxta-anellus, and a dorsal enlargement of the tegumen, often as a small flaplike extension. It is primarily on the basis of the male genitalia features that the species described here is placed in Sternitta. This species bears at least three features that contradict Fibiger`s general diagnosis of Sternitta, which can be modified with respect to the following characters (changes in italics): forewing without or with costal patch; crosslines not all prominent, dark brown or black; vesica unarmed or with a cornutus.
