Pseudodendrothrips Schmutz

Pseudodendrothrips Schmutz, 1913: 998 . Type species: Pseudodendrothrips ornatissimus Schmutz, 1913 , by monotypy.

Macropterous, body small and fragile. Head transverse, occipital region narrow; usually two pairs of anteocellar setae, pair I sometimes absent, pair II small and posterolateral to fore ocellus, pair III within ocellar triangle ( Fig. 23 ); mouth-cone sometimes moderately long and pointed at apex, with 2-segmented maxillary palpi ( Fig. 24 ); compound eyes large. Antenna 8- or 9-segmented (Fig. 33), segments III and IV with forked sensoria, III–VI with microtrichial rows on both dorsal and ventral surfaces, VII completely or incompletely divided. Pronotum transverse, with median transverse internal ridge that is weak at middle, distinctly sculptured with transverse anastomosing lines throughout; four pairs of setae present on posterior margin to posterior angles, S4 setae longest. Mesonotum with a transverse internal ridge, smooth anterior to the ridge but densely sculptured with transverse anastomosing lines posterior to the ridge; median pair of setae near level of submedian pair; anteromedian CPS absent. Metascutum without CPS; median pair of setae far from anterior margin (Fig. 34). Prosternal ferna widely divided; basantra without setae; prospinasternum Y-shaped, narrow but distinct. Meso- and metasterna without spinula. Metaepimeron not developed. Metaepisternum sclerotized and unsculptured on posterior half, not elongate and narrow toward apex, without hook-like apex (Fig. 35), sculptured anteriorly. Fore wing pointed at apex and with a long apical seta; first vein with about seven scattered setae, second vein without setae; anteromarginal fringe arising from ventral surface of costa; posteromarginal fringe not wavy; clavus with two veinal and a discal seta. Hind tibia ventrally with an apical spine-like seta, hind tarsi at least 0.5 times as long as hind tibia (Fig. 36). Abdominal tergites not divided from pleurotergites, with S1 setae close to each other, much longer than their interval, S2 setae slightly sinuate ( Fig. 38 ); tergites II–VIII with six pairs of setae, sculptured with transverse anastomosing lines having numerous small longitudinal ridges lateral to S2 setae; tergite VIII with complete posteromarginal comb; tergite IX with numerous microtrichia on posterior half, MD setae lateral and small; sternites without discal setae, III–VII with three pairs posteromarginal setae, but II with two pairs. Male without pore plates on abdominal sternites.

Comments. 20 species are known from the Old World and about half of them are associated with Moraceae . Previously in Japan only two species have been known but a further three species are here newly added. In contrast, three species, fumosus , lateralis and mori have been known in Taiwan ( Wang, 2002).
