description: Baguoidea Mahmood
Baguoidea Mahmood, 1967: 40. Type species. Baguoidea rubra Mahmood, 1967, by original designation.
Redescription. Body relatively robust, red. Head equally wide as pronotum or slightly wider (Fig. 15). Vertex short, rounded anteriorly, profile of transition vertex to face rounded, coronal suture distinct (Fig. 15). Face short (Fig. 16), apparently convex in lateral aspect, lateral frontal suture present. Fore wing narrow, 3 apical veins arise from longitudinal m cell, 2nd apical cell slightly broadened towards apex, veins RP, MP’ stalked, 4th apical cell shortest, c and r cells nearly equal in width, both narrower than m and cua cells (Fig. 17); in hind wing area bordered by vannal veins small, vein CuA unbranched apically (Fig. 18).
Abdodminal apodemes well developed with tips widely divergent posteriorly (Fig. 27). Male pygofer elongate, apical half of pygofer strongly narrowing caudad, with rigid macrosetae on each side of pygofer lobe, dorsal margin produced with lobe directed caudad (Figs. 19, 21), ventral appendage present (Figs. 19– 21); dorsal bridge quite long, caudo-dorsal part with vertical sclerotization cephalad (Fig. 21). Subgenital plate far exceeding pygofer side, broad at base, anterior margin straight in apical half, ventral margin curved dorsad leading to the plate narrowing terminally, with long, stout and bluntly terminated macrosetae in one row in basal group and laterally in one to two rows on disc followed by densely arranged macrosetae apically (Fig. 26). Paramere serrate apically, setae and sensory pits basad of serrations (Fig. 25). Connective fused with base of aedeagus (Figs. 22, 23). Aedeagus without preatrium and dorsal apodeme, shaft tubular, compressed, ending in paired apical processes which are directed laterad, each having teeth at apex, gonopore apical (Figs. 22, 23). Anal tube process broad, curved and narrowing apically with subapical ligament connection from dorsal margin (Fig. 24).
Remarks. The original description and illustrations of Mahmood (1967) were obscure; in particular, his illustrations and description of the genus do not match very well, particularly those of the pygofer. Mahmood stated: “pygofer with a lobe-like structure produced caudad, pygofer process ventral in origin, of varying shape, directed dorsal and caudad”, but his illustration appears to show a long, thin projection of the pygofer directed caudo-dorsad and does not appear to show any ventral pygofer process. The main diagnostic features of the genus described by Dworakowska (1973) were as follows: “the most characteristic feature in head structure is absence of lateral frontal suture and in male genitalia apparatus joining penis-connective shifted away from end of manubrium”. Baguoidea specimens deposited in NWAFU match the Mahmood description of the pygofer and pygofer process (Figs. 19, 20) but, in contrast to Dworakowska’s description, the lateral frontal suture is well developed (Fig. 16) and the male genitalia have the connective fused with the base of the aedeagus (Figs. 22, 23). Therefore the genus is redescribed here, and a new species, B. yunnanensis Qin & Zhang from Yunnan, China, is described.
Baguoidea belongs to the Usharia Dwor. group and differs from Homa Dist. in having veins RP, MP’ of the fore wing stalked (separate in Homa), the abdodminal apodemes well developed with tips divergent from each other (vestigial with tips not divergent in Homa), and the subgenital plate with dense macrosetae apically (without apical macrosetae in Homa).
Distribution. China (Yunnan Province), Philippine, Malaysia.
