EUBRONCUS Yoshimoto, Kozlov & Trjapitzin, 1972

( Figs 137–146 )

Eubroncus Yoshimoto, Kozlov & Trjapitzin, 1972: 879 . Type species: Eubroncus orientalis Yoshimoto, Kozlov & Trjapitzin, 1972 , by original designation.

Stomarotrum Yoshimoto, Kozlov & Trjapitzin, 1972: 881 . Type species: Stomarotrum prodigiosum Yoshimoto, Kozlov & Trjapitzin, 1972 , by original designation. Synonymy by Triapitsyn & Huber, 2000: 603.

Diagnosis. Head strongly produced anteriorly, in lateral view almost triangular ( Fig. 142 ); face with rectangular projection between toruli ( Fig. 138 ); female antenna with funicle segments mostly shorter than wide ( Fig. 137 ); mandibles as long as head height, projecting anteriorly and not crossing medially ( Fig. 142 ); hind wing relatively wide with bluntly rounded apex ( Fig. 139 ); protibial spur comb-like, with numerous setae.

Discussion. Eubroncus belongs to the Cleruchus group of genera. In the Afrotropical region this group also includes Cleruchoides , Cleruchus , and Platystethynium . Triapitsyn & Berezovskiy (2002) first mentioned Eubroncus for the region. It is most similar to the extralimital Anagroidea Girault ; both are probably best placed as a subgroup in the Cleruchus group of genera.

Afrotropical hosts. Unknown.

Distribution. No species described for the Afrotropical region. Specimens from Comoros, Kenya, Madagascar, Republic of the Congo, and Uganda were examined (CAS, CNC, UCRC).
