Studied type specimens.

Holotype of Mixogaster vespiformis Brunetti, 1913 . India • 1 ♂; N. E. Assam, Dibrugarh ; 17–19 Nov. 1911; ZSI. Label 1: “ Ind. Mus. // Dibrugarh // N. E. Assam // Abor Exped // 17–19 - XI- 11. // Kemp [printed vertically on left side of label] ”; label 2: “ Mixogaster // vespiformis // Brun. Typ. ♀ ”; label 3: “ Paramixogas- // ter. // vespiformis // Brun Type ♀ // det. Brun. 1923 ”; label 4: “ 2177 // [illegible 2 digit code] ” [digital images studied].

Diagnosis.

Only male known. Body length: 8 mm. A reddish-brown species with lateral bulges on the frons. From most other species with lateral bulges on the frons, it differs by the combination of the following characters: tergite 2 less than twice as long as wide, mesoscutum without fascia of golden setulae along transverse suture. This species is most similar to P. halmaherensis and P. yunnanensis , but differs because the mesoscutum is reddish with a median black vitta of ~ 1 / 3 of the width of the scutum (mostly dark brown to blackish in the other two species), and tergite 2 is reddish at least on the apical 1 / 2 (at most narrowly reddish along posterior margin in the other two species).

Notes.

Mixogaster vespiformis Brunetti, 1913 was included in Paramixogaster by Brunetti (1923). The species name became a secondary homonym when Microdon vespiformis de Meijere, 1908 was transferred to Paramixogaster by Reemer and Ståhls (2013 a), who introduced the replacement name Paramixogaster brunettii Reemer, 2013 . The type specimen itself has not been studied by the authors, but digital images were kindly provided by Jeroen van Steenis.

Distribution.

Only known from Assam ( India).
