A new species of Heminicsara (Orthoptera: Tettigoniidae: Agraeciini) from West Papua (New Guinea)

Katydids of the tribe Agraeciini are highly diversified in species number and morphology. In the Southeast Asian and Oriental regions, the first major taxonomic revision of Agraeciini was done by Ingrisch (1998). This led to further new species discoveries and taxonomic treatments of specific groups (Gorochov, 2011, 2015, 2016; Ingrisch & Tan, 2012; Tan & Ingrisch, 2014; Tan et al., 2018). Many of these publications focus on species from areas west of the Wallace Line. To the east of Wallace Line, Willemse (1959) provided a thorough revision of the genus Salomona which includes many species from, but not limited to New Guinea nor to the east of the Wallace Line. More recently, monographic contributions to the taxonomy of Agraeciini from New Guinea and surrounding regions also include Heminicsara Karny, 1912 is a katydid genus of Agraeciini from the Axylus genus group. It currently comprises 62 species from mainly New Guinea and surrounding archipelagos. Based on recent fieldwork in Lobo in West Papua, Indonesia, a new species of Heminicsara is described here: Heminicsara incrassata sp. nov. It is most readily characterised from congeners and other species of the Axylus genus group by the male tenth abdominal tergite forming a large shield-shaped plate. This represents the first species of Heminicsara described and known from the south-west of New Guinea.
