Abstract
The identities of two species of assassin bugs in the tribe Ectinoderini (Hemiptera: Heteroptera: Reduviidae: Harpactorinae) from the Indochinese Peninsula are reviewed, resulting in the following new synonymy and new combinations: Amulius Stål, 1865 = Parapanthous Distant, 1919, syn. n.; Amulius spinicollis (Distant, 1919), comb. n. (transferred from Parapanthous) and Ectinoderus confragosus (Distant, 1919), comb. n. (transferred from Amulius). Lectotypes of these species are designated. The hemelytral venations of Amulius and Ectinoderus Westwood, 1843 are briefly discussed and their diagnoses accordingly revised. Amulius is newly reported from Vietnam and Ectinoderus is recorded from Cambodia for the first time.
Highlights
Members of the Oriental and Pacific assassin bug tribe Ectinoderini (Hemiptera: Heteroptera: Reduviidae: Harpactorinae) are noteworthy for applying sticky plant resins to their fore legs to help them catch their prey (Schuh & Weirauch, 2020)
It was regarded as a distinct subfamily of Reduviidae or included in the Apiomerinae ( Apiomerini of Harpactorinae), but more recently considered a tribe of Harpactorinae based on a morphological phylogeny of the Harpactoroid Complex (Davis, 1969)
During the present study we examined eight species of Amulius and nine species of Ectinoderus (Table 1), and observed differences in hemelytral venation between the two genera
Summary
Members of the Oriental and Pacific assassin bug tribe Ectinoderini (Hemiptera: Heteroptera: Reduviidae: Harpactorinae) are noteworthy for applying sticky plant resins to their fore legs to help them catch their prey (Schuh & Weirauch, 2020).
