Lazányi, Eszter & Korsós, Zoltán, 2011, Revision of the Megaphyllum projectum Verhoeff species complex (Myriapoda: Diplopoda: Julida: Julidae), Zootaxa 2864, pp. 43-56 : 53

Key to the subspecies of Megaphyllum projectum

Based on male and female genitalia characters; female of M. p. deubeli not included because it needs further investigation.

1 Male ............................................................................................... 2

- Female.............................................................................................. 4

2 Anterior process of opisthomere rudimentary, shorter than the well-developed posterior process ( Fig. 10 ). Promere triangular, without apical serrated lobe................................................ M. projectum deubeli ( Verhoeff, 1899)

- Anterior and posterior processes of opisthomere of approximately the same length and development ( Fig. 3 ). Promere with a serrated apical lobe (by M. p. kochi this serrated lobe sometimes not visible under a standard light microscope, just under stereo microscope, at high magnification).................................................................. 3

3 Promere tapering, the whole gonopod in situ appears to be thin ( Figs. 14–15 )......... M. projectum kochi ( Verhoeff, 1907)

- Promere not tapering, the whole gonopod in situ appears to be stout ( Figs. 1 , 16 ).... M. projectum projectum Verhoeff, 1894

4 Ampullas well-developed, dorsal ampulla wide, bulbous, ventral ampulla elongated ( Figs. 8 a–c)............................................................................................ M. projectum projectum Verhoeff, 1894

- Ampullas thin, elongated, dorsal ampulla not bulbous M. projectum kochi ( Verhoeff, 1907)
