Homa Distant, 1908

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 : 556

Genus Homa Distant, 1908

Homa Distant, 1908: 400 . — Mahmood 1967: 44. — Qin et al. 2011: 31 (description); 2014: 1498 (key). — Xu et al. 2022 (revision).

TYPE SPECIES. — Homa insignis Distant, 1908 , by original designation.

DISTRIBUTION. — Widespread in Asia and the West Pacific.

REMARKS

Homa has similarities to both Baguoidea and Dayus (see Introduction and Remarks under those genera). It differs externally from these genera by its distinctive forewing colour marking (see Fig. 1H, J ). Two additional characters to the generic description of Mahmood (1967) are the reduction or absence of male third basal abdominal sternal apodemes and the presence of a dorsal connective attached to the aedeagus in the phragma of the male pygofer. Mahmood (1967: 44) noted an undescribed species from the Philippines and here also the senior author has seen two undetermined female specimens from the Philippines (NHM) which, based on distribution, might possibly be Homa katoi Dworakowska, 1984 . Several other new species from the Pacific ( Sarawak, Brunei and Sulawesi) have also been seen (NHM). Homa elongata Kato, 1929 was transferred to Asialebra Dworakowska by Dworakowska (1993: 101). In the key to species by Qin et al. (2011), the last couplet should read H. insignis not H. haematoptila and in the key to species provided by Xu et al. (2022), similarly the reference to H. haematoptila should read H. insignis (for explanation see H. haematoptila below).
