Crassabwa  ? vitrea ( Navás 1930) 

( Figs 133–134View FIGURES 133 – 134).

Cloeon vitreum Navás 1930: 322  (♀ imago);

Centroptilum vitreum: Demoulin 1957: 262  (♀ imago); Afroptilum vitreum: Gillies 1990: 99  ;

Crassabwa vitrea: Lugo-Ortiz & McCafferty 1996b: 239  .

Cloeon vitreum Navás 1930  was described as a single female imago from Belgian Congo. Demoulin (1957) redescribed the holotype and placed it to Centroptilum  , noting its similarity with Centroptilum flavum Crass 1947  . Based on this, Gillies (1990) placed this species to the group tarsale of the genus Afroptilum  , and Lugo-Ortiz & McCafferty (1996b) placed it to the newly established genus Crassabwa  . The single specimen has no legs and cerci, so their structure and coloration are unknown ( Demoulin 1957). Shape of wings ( Demoulin 1957: Fig. 3View FIGURES 1 – 4) is in agreement with characteristic of Crassabwa  [see characters (20), (21)], but this is not enough to determine its systematic position for certain.

Demoulin (1957) reported that coloration of C. vitreum  is somewhat different from that of C. flavum  . The holotype of vitreum Navás 1930  [ Cloeon  ] is deposited in the «Musée royal de l’Afrique centrale» in Tervuren, Belgium. Photographs of the holotype, kindly made by specialists of this museum, allow to conclude that vitreum  [ Cloeon  ] differs from Crassabwa flava  and C. ludmilae  sp. n. by unicolor dark brown dorsal surface of female head ( Fig. 133View FIGURES 133 – 134) (which in C. flava  and C. ludmilae  is light ocher with brownish—Figs 33, 96) and by unicolor abdomen ( Fig. 134View FIGURES 133 – 134) (which in C. flava  , C. ludmilae  sp. n. and C. ameliae  sp. n. has sterna contrastingly lighter than terga—Figs 34, 97, 120).
