DIAGNOSIS: Differentiated from similar taxa by characters listed in generic diagnosis and discontinuous red maculations along dorsal margin of propleuron, most prominent anteriorly; genital capsule without lateral tubercle; aedeagus with relatively small, serrated, hatchetlike lobal sclerite ( fig. 4d–e ). Females with long medially oriented setae on posterior margin of corium ( fig. 1c ). Fig. 2. Scanning electron micrographs of Morobea longipes . a. Head and pronotum, dorsal view. b. Head and pronotum, ventral view. c. Head and pronotum, lateral view. d. Pretarsus, ventral view. e. Meso- and metathorax, lateral view. f. Evaporative area (scale bars 5 50 m m). REDESCRIPTION: Coloration ( fig. 1a ): Head yellowish brown with vague red maculations on clypeus and mandibular plates. Antennae yellowish brown becoming darker distally. Prothorax yellowish brown, tinged with green in some specimens; disc and collar undifferentiated; dorsal margin of propleuron with red maculation at anterolateral margin, undifferentiated ventrally. Scutellum yellowish brown, sometimes suffused with blue-green. Hemelytra predominately yellowish brown; margin of clavus weakly suffused with red along scutellar margin; cuneus ringed with red. Abdomen yellow with dorsal surface of male genital capsule dark brown. Legs predominately yellow, becoming brown distally, ventral surface suffused with blue-green; metafemur with pale brown spots on anterior surface and red distally. Structure : As in generic description with the following additions. Head with weak sulcus along length of vertex and frons; antennal segment II weakly swollen as base, swollen portion with dense field of short hairs oriented perpendicular to antennal surface ( fig. 3a ). Cuneus 2.5 times longer than broad, subtriangular. Small cell of hemelytral membrane less than one-third length of cuneus. Genitalia ( fig. 4 ): Genital capsule broadly subconical with large aperture; dorsal projection of ventral rim roughly symmetrical, slightly skewed to left, broadly rounded; ventral projection of ventral rim asymmetrical skewed left, acute. Parameres as in generic description; right paramere with small apical lobe. Theca sclerotized basally, distally convoluted into several large flanges and hooks; apical serrate process relatively small and hatchetlike. Aedeagus as in generic description. Fig. 3.

FEMALE ( fig. 1b ): Similar to males except antennal segment II simple; cuneus 1.5 times longer than broad, subrectangular; posterior margin of corium with large medially oriented setae, hairs longer than width of large cell ( fig. 1c ); small cell of hemelytral membrane minute, almost obsolete; medial portion of membrane with large field of short velutinous hairs. Genitalia : Ovipositor as in generic description. Internal genitalia unknown due to damaged material.
