description: Homa Distant, 1908
Homa Distant, 1908: 400. Type species: Homa insignis Distant, 1908 = Homa haematoptilus (Kirkaldy, 1906)
Diagnosis. Body white or stramineous, usually with bold symmetrical red markings dorsally. Head including eyes distinctly broader than pronotum in dorsal view (Figs 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 78, 81). Crown slightly longer medially than next to eye, coronal suture short, not extended beyond mid-length of crown (Figs 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 78, 81). Eyes large, as wide as distance between basomedial angles (Figs 3, 7, 11, 15, 19, 78, 81). Ocelli distinct, separated from eyes by less than half of ocellar diameter (Figs 4, 8, 12, 16, 20, 82). Face broad and convex in profile, lateral frontal suture not extended ventromesad of ocelli, anteclypeus strongly swollen and broadened in some species (Figs 4, 8, 12, 16, 20, 82). Forewing narrow, rounded apically, veins R2, RM and MCu dissociated at their base, all arising from m cell. Hind wing with CuA and MP fused for entire length (Figs 21, 22).
Front femur row AV with 1 basal seta distinctly enlarged or setae subequal or gradually decreasing in size distally; AM1 distinctly enlarged. Middle femur with 1 dorsoapical macroseta. Hind tibia row AV with 4 preapical macrosetae.
Male basal abdominal sternal apodemes (1T apodemes) developed, 2S and 3T apodemes absent (Figs 23, 26, 29, 32, 35, 83). Male pygofer elongate, with few rigid microsetae along posterior margin, ventral appendage absent, dorsal bridge well developed (Figs 24, 25, 27, 28, 30, 31, 33, 34, 36, 37, 84, 85). Subgenital plate broadest at base and narrowing apically toward sclerotized and pigmented apex; basal setae densely grouped and stout, blunt-tipped; marginal microsetae rare, along dorsal margin of plate; macrosetae uniseriate, not reaching tip of plate; feeble microsetae present (Figs 24, 27, 30, 33, 36). Style base broad and distinctly bent mesad at point of articulation to plate, terminating in a strong arcuate and abruptly narrowed apical dentifer, dentifer with a few, small teeth, subapically with several setae and few sensory pits (Figs 44, 52, 60, 67, 76). Aedeagal shaft tubular, with or without process(es), dorsoatrium absent. Connective fused with the base of aedeagus (Figs 42, 43, 50, 51, 58, 59, 65, 66, 73–75). Anal tube with basal anterior appendage well developed (Figs 45, 53, 61, 68, 77).
Remarks. Homa is unique among known genera of the Usharia group (Xu et al., 2021) in having 1T apodemes (Figs 23, 26, 29, 32, 35, 83). This feature is rare in Empoascini, most genera of which have a well-developed 2S apodemes or 3T apodemes. It is similar to Baguoidea Mahmood, 1967 in body shape and color, but differs in having forewing veins R2 and RM dissociated at their base (Fig. 21) (confluent for a short distance in Baguoidea Mahmood, 1967); and in lacking a pygofer appendage (ventral appendage present in Baguoidea Mahmood, 1967).
Distribution. China (Yunnan and Taiwan Provinces), Thailand, Vietnam, Japan, Sri Lanka, Philippines, Malaysia, Australia.
