Similiar species:
Rather small Geometrinae with wingspan of ~30 mm. Numerous other members of the genus Hemithea are found in India. Holloway (1996) writes "Members of the [tritonaria] complex are only reliably separated by examination of the male genitalia."

Hemithea Duponchel, 1829 species known from India are listed. 
Hemithea antigrapha Prout, 1917. Khasi Hills, Meghalaya.
Hemithea aquamarina Hampson, 1895. Dharamsala, Khasis.
Hemithea himachalensis Walia, 2000. Himachal Pradesh (Nauni).
Hemithea insularia (Guenée, [1858]). Indian subregion.
Hemithea marina (Butler, 1878). Indian subregion.
Hemithea melalopha Prout, 1931. Khasi Hills, Meghalaya.
Hemithea ochrolauta (Warren, 1894). Uttarakhand, Nagaland; Bhutan. 
Hemithea tritonaria (Walker, 1863). Khasis, Nilgiris, Karnataka, Tamil Nadu
Hemithea wuka (Pagenstecher, 1886). Nilgiris. 

Hemithea insularia profecta Prout, 1933. Listed as synonym of Hemithea melalopha in MOB. But Plotkin et al 2020 lists both Hemithea insularia and Hemithea melalopha as valid species in their checklist of Geometrinae. 

There are reports of Hemithea costipunctata (Moore [1868]) from India (Sondhi et al. 2016; Dey et al. 2018), but Lepindex treats Hemithea costipunctata as a synonym of Hemithea marina (Butler, 1878) and Plotkin et al. 2020 do not list Hemithea costipunctata as a valid species in their global checklist of Geometrinae.
