Thaumastodus Champion, 1924a: 25 (type species: Thaumastodus fusiformis Champion, 1924; synonymized by Champion 1924b). Pseudeucinetus – Satô 1994: 173. — Spangler 1995: 395. Diagnosis Body oblong. Gena wide; shallow antennal groove present.Frons (Fig. 2 E–F) narrow, distinctly projecting anteriorly. Antennae stout and short, 11-segmented; antennal insertions situated near mandibles. Legs relatively short and stout; tarsal formula 4-4-4; male fore tarsi enlarged (Fig. 3E). Remarks This genus is easily distinguishable from other genera of the subfamily Thaumastodinae by the unique shape of the head: frons distinctly projecting anteriorly and narrow between the eyes. Biological notes The habitat of this genus (Fig. 4A) is freshwater environments, i.e., rivers and streams. The adults are found in the splash zone of wet rocks, and frequently actively flying. In Java, Indonesia, Pseudeucinetus javanicus and Acontosceles javanicus were collected in the same place (Yoshitomi & Putra 2011). The adults were also collected by light trap.
