Eye at least superficially bare (Figs 36–38).

Tegula elongate-triangular with almost truncate posterior margin. Mesoscutum (Fig. 39) not shoulder-like posterior to pronotum, as long as greatest width, and with posteriorly ridge-like, parallel parapsidal lines (Fig. 39: psr) differentiating slightly concave, elongate-rectangular median region from inclined lateral regions; sparsely and inconspicuously setose; median mesoscutal region with larger and more distinct mesh-like reticulation than on pronotum, lateral mesoscutal regions with sculpture similar to median region but apparently shallower, more coriaceous toward lateral margin, and parapsidal lines with much smaller and finer coriaceous sculpture. Scutellar-axillar complex with distinct, longitudinally crenulate scutoscutellar sutures (Figs 39, 40: sss) differentiating convex axillae and scutellum; axillae equilateral-triangular with contiguous inner angles, with finer coriaceous sculpture compared to mesoscutum, and without distinct setae; scutellum not laterally carinate, coriaceous-imbricate anteriorly to meshlike-reticulate posteriorly and apparently quite uniformly and sparsely setose, protuberant posteromedially, the protuberance (Fig. 40: scp) projecting ventrally into medial depression of metanotum.

Propodeum in dorsal view (Figs 40, 41) very short; plical region strongly transverse with shallowly incurved foramen (Fig. 40: pfr) and apparently slightly concave medially under scutellar-metanotal protuberance; spiracle near midlength laterally. Prepectus (Figs 35, 41: pre) conspicuously elongate-triangular, the apical half abruptly narrowed and tapered to acute angle. Mesopleuron (Fig. 41) with uniformly convex acropleuron extending posteriorly to region between bases of meso- and metacoxae, with linear acropleural sulcus (Fig. 41: acs) extending forward from mesocoxa to level about equal with base of tegula where abruptly recurved dorsally as obscure arcuate line extending to prepectus near apical third; acropleuron bare, mesh-like reticulate anteriorly to more finely coriaceous posteriorly, the sculpture elongated and more or less aligned in rows posteriorly; mesepisternum sparsely setose anterior to arcuate portion of acropleural sulcus and ventral to horizontal portion of sulcus (Fig. 41: mes) except for bare, triangular remnant of mesepimeron (Fig. 41: lep) between acropleuron and mesosternum. Metapleuron uniformly setose, strongly tapered ventrally so as to extend as almost linear strip (Fig. 41: pl3) between acropleuron and metacoxa to base of mesocoxa. Mesosternum (Fig. 34) with deep sulcate discrimen, without transepisternal sulcus, and with straight-transverse posterior margin abutting mesocoxae. Protibia apparently with apical spicule. Middle leg conspicuously long (Figs 33–35), about as long as body and longer than hind leg; mesocoxa with large basolateral cavity opposite angle formed between acropleuron and mesepisternum (Fig. 41: mcc); mesotibia with row of dark, variably long spines along apical margin (Fig. 43: map) and with mesotibial spur about 3x as long as apical width of tibia; mesotarsus (Fig.43) slender with subcylindrical seg-

Fore wing hyaline (Figs 33, 42); costal cell extensively setose along leading margin; basal cell and disc uniformly setose except for linea calva (Fig. 42: lc) behind parastigma, anterior margin of bare band delimited by slightly thicker microtrichia; cubital and vannal areas apparently bare; cc: mv: pmv: stv = 5.5: 2.7: 3.1: 0.9; stigmal vein with distinct uncus. Gaster very broadly sessile, with at least seven uniformly setose gastral tergites; cercus (Fig. 44: cer) at extreme posterior margin of terminal segment; terminal segment with transverse suture (Fig. 44: sut) anterior to cercus delimiting apparently fused Gt7 and Gt8, the presumptive Gt8 comprising about apical quarter of syntergum and length of syntergum about 0.6× length of Gt
