Crassabwa View in CoL View at ENA ? vitrea ( Navás 1930)

( Figs 133–134 View 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 View in CoL .

Cloeon vitreum Navás 1930 was described as a single female imago from Belgian Congo. Demoulin (1957) redescribed the holotype and placed it to Centroptilum View in CoL , noting its similarity with Centroptilum flavum Crass 1947 . Based on this, Gillies (1990) placed this species to the group tarsale of the genus Afroptilum View in CoL , and Lugo-Ortiz & McCafferty (1996b) placed it to the newly established genus Crassabwa View in CoL . The single specimen has no legs and cerci, so their structure and coloration are unknown ( Demoulin 1957). Shape of wings ( Demoulin 1957: Fig. 3 View FIGURES 1 – 4 ) is in agreement with characteristic of Crassabwa View in CoL [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 View in CoL ] 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 View in CoL ] differs from Crassabwa flava View in CoL and C. ludmilae sp. n. by unicolor dark brown dorsal surface of female head ( Fig. 133 View FIGURES 133 – 134 ) (which in C. flava View in CoL and C. ludmilae is light ocher with brownish—Figs 33, 96) and by unicolor abdomen ( Fig. 134 View FIGURES 133 – 134 ) (which in C. flava View in CoL , C. ludmilae sp. n. and C. ameliae sp. n. has sterna contrastingly lighter than terga—Figs 34, 97, 120).
