Hollmann-Schirrmacher does not make me very happy. There is no key to all Philygruia species but only to those with a single row of acrostichals (my specimens have none). Furthermore, there are a number of species with 'reduced wings', which I think are similar to the 'macropterous' specimens I have (wing tip then probably at level of abdominal tip). But my brachypterous specimen is truely brachypterous, so wing even further shortened and narrowed, so that the wing venation is also reduced: the major veins are the radial veins and vein M1+2 (the costa extending to that vein), but no veins posterior of that because there practically is not any wing left there. Non of the species mentioned by Hollmann-Schirrmacher seems to want to accomodate that specimen of mine.
But there is one 'maybe': One way or the other, semialata is not mentioned by Hollmann-Schirrmacher... Due to some unclear references in the book I cannot be entirely certain why the species is not mentioned. Of the former genus Nostima only picta and flavitarsis are mentioned and according to him it should be substantiated elsewhere in the book why other species (he does not even mentioned which ones) are not discussed. Possibly semialata is one of them. Oddly enough, he mentions that THE species of Philygria are discussed in chapter 4.5. Well, not all of them it turns out.
