Descriptions of new Tortricidae (Lepidoptera) reared from native fruit in Kenya Author Razowski, Józef Author Brown, John W. text Zootaxa 2012 3222 1 27 journal article 45308 10.5281/zenodo.280255 9d264785-6035-49e2-b6cf-29e3022a6e80 1175-5326 280255 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 ).
