Diagnosis.

Body length: male 9–12 mm (n = 3); female 10 mm ( Sack 1922). This species differs from all other known species of Paramixogaster by its unique colour pattern: the mesoscutum is largely yellow, with small two black maculae posterior to the postpronotum and two elongate narrow black maculae between the transverse suture and the posterior margin (Fig. 21 View Figures 21, 22 ). Tergites 3 and 4 are yellow with a unique pattern of black vittae (Fig. 95 View Figures 95–101 ). Male genitalia as in Fig. 133 View Figures 130–137 .

Notes.

Sack (1922) described Myxogaster variegata based on two female syntypes. Attempts to locate the types at the German institutions DEI and ZMHU were unsuccessful (Eliana Buenaventura, Sven Marotzke, Frank Menzel and Joachim Ziegler pers. comm. 2020). The syntypes are considered to be lost. However, the description and figure by Sack (1922) provide enough information to identify the studied specimens as this species. We designate here a neotype to ensure the proper and consistent interpretation of the name.

Shiraki (1930) found out that this species is not closely related to the New World genus Mixogaster Macquart, 1842 and erected a new genus for it: Paramixogasteroides Shiraki, 1930 . He also gave a redescription of the species based on a male and a female. Paramixogasteroides was synonymised with Paramixogaster by Cheng and Thompson (2008), which was followed by Reemer and Ståhls (2013 a) and in this paper.
