Thylacogaster Diakonoff, 1988

Type species: Thylacogaster rhodomenia Diakonoff, 1988 .

Thylacogaster was described by Diakonoff (1988a) for the single species T. rhodomenia . Razowski (2004) provided a brief diagnosis of the genus in his review of the genera of the Afrotropical region. Brown (2005) added Argyroploce cyanophaea Meyrick, 1927 (TL: “Tanganyika”) and Argyroploce monospora Meyrick, 1939 (TL: “ Belgian Congo ”) without comment, based on input from Leif Aarvik (in litt.). The adult and male and female genitalia of T. rhodomenia are illustrated by Diakonoff (1988a: figs. 13–16), the adult and female genitalia of T. cyanophaea are illustrated by Clarke (1958: 500), and the adult and male and female genitalia of T. monospora are illustrated by Razowski et al. (2010).

Razowski and Brown (2008) mentioned several similarities between the Neotropical genus Eriosocia Razowski and Brown, 2008 and the Afrotropical Thylacogaster , including the conspicuous notch near mid-termen of the forewing; the overall shape of the phallus; the dorsolateral position of the socii; the pair of small, finely and sparsely setose lobes at the lateroposterior corners of the ostium bursae; the extremely long, slender ductus bursae; the slightly telescopic ovipositor; and the fact that both genera have been reared only from Garcinia species ( Clusiaceae ).
