Webb, Michael D. & Xu, Ye, 2022, Review of the “ red ” Empoascini leafhoppers in the genera Baguoidea Mahmood, 1967, Dayus Mahmood, 1967 and Homa Distant, 1908 (Hemiptera, Cicadellidae, Typhlocybinae) from Asia and the West Pacific, Zoosystema 44 (22), pp. 549-563 : 551

Genus Baguoidea Mahmood, 1967

Baguoidea Mahmood, 1967: 40 . — Qin et al. 2010: 55 ; 2014: 1498 (key).

TYPE SPECIES. — Baguoidea rubra Mahmood, 1967 by original designation.

DISTRIBUTION. — Mainland Asia ( Sri Lanka, Myanmar and China), Philippines and Japan (?), see Remarks of B. rufa below.

REMARKS

This monotypic genus is tentatively regarded as distinct from Dayus . It differs only in having the basal group setae of the subgenital plate blunt-tipped (also found in some Homa species) and distal macrosetae more numerous ( Fig. 3L ) and in lacking an unusual ventral apodeme of the 8 th abdominal sternite, found in Dayus . In other respects, it is similar to Dayus in its overall red colour, having the 3rd apical cell in the forewing petiolate ( Fig. 3C ), male pygofer with processes ( Fig. 3G ), form of the subgenital plate and aedeagus and well developed male basal dorsal abdominal apodemes ( Fig. 3M ). The genus was redescribed by Yu & Yang (2013) as there were some errors in Mahmood’s original description and figures, which also had implications on subsequent studies (see Remarks under B. rufa below). Yu & Yang (2013) also noted that Dworakowska (1973) had stated (and figured) that the facial laterofrontal sutures were absent in Baguoidea but were present in their specimens, and are also present in the specimens studied here. This apparent mistake by Dworakowska may have been due to the sutures being obscure against the red facial colour.
