Female. Macropterous. Head slightly wider than long, usually slightly narrowed to base; cheeks usually straight, sometime slightly rounded; mouth­cone usually more or less long and pointed at apex, sometime very long and reaching to mesothorax, with 3­segmented maxillary palpi (cf. Figs. 1, 92). Compound eyes usually with five weakly (sometime strongly) pigmented ommatidia on ventral surface (cf. Figs. 22, 119, 142). Ocellar setae I usually present, sometimes setae I and II absent ( Figs. 87, 92), rarely only setae II absent ( Fig. 14), setae III situated within ocellar triangle, usually long and stout. Postocular setae usually five pairs, setae II and III usually closer to each other than to I and IV. Antennae usually 8­segmented, rarely 7­segmented ( Fig. 135a); segment I with two dorsal apical setae (total 13 setae; 6 on dorsal, 7 on ventral) (cf. Fig. 135b), II usually with a mid­dorsal seta below CPS and usually with some microtrichial rows on dorsal surface, III and IV with forked sense­cones, III to VI with some microtrichial rows on both dorsal and ventral surfaces. Number of setae on antennal segments II to VI as follows: 7, 5, 5, 6, 9–16.

Pronotum usually wider than long, with two pairs of long posteroangular setae and two pairs of posteromarginal setae. Mesonotum sculptured with transverse anastomosing striae; CPS present or absent anteromedially. Metascutum longitudinally or irregularly reticulated medially; median pair of setae usually at or near anterior margin; CPS absent. Prosternal ferna undivided but connected weakly at middle. Mesosternopleural suture weak and incomplete, not reaching anterior margin; endofurca with developed spinula. Metathoracic endofurca usually with well­developed spinula (often reduced in M. latus ). Metaepisternum without setae. Metapreepisternum developed and with a seta. Fore wings first vein with a median long gap in setal row, six to ten (usually seven or eight) basal and two distal setae, second vein with evenly narrow­spaced setal row, posterior fringe cilia wavy; scale with five (rarely four or six) veinal and one discal setae. Tarsi 2­segmented.

Abdominal terga without ctenidia and posteromarginal craspeda; terga I or II to VIII laterally and laterotergites often with numerous regular ciliate microtrichia along lines of sculpture (cf. Fig. 5), if without, often with small scattered dentate microtrichia (cf. Figs. 29–30, 53); tergum VIII with complete long, fine posteromarginal comb; tergum X with or without median slit distally (cf. Figs. 7, 139, 151); sterna without posteromarginal craspeda; sterna III to VII usually with six (II with four) posteromarginal setae, median pair of setae of VII usually in front of posterior margin; sterna often with discal setae in addition to posteromarginal setae; laterotergites without discal setae. Ovipositor developed.

Male. Macropterous (apterous in M. annulicornis ). General structure and colour as in female but smaller and abdomen slender. Antennae usually 8­segmented, sometime 6­ or 7­segmented (cf. Figs. 3, 18); segment VI varying in length, much longer than that of female in some species, but about as long as that of female in other species, when much longer than in female, with numerous long setae and without microtrichial rows (cf. Figs. 47, 59, 76). Abdominal tergal microtrichial rows, if present, usually fewer and smaller than in female (cf. Fig. 49); tergum IX usually with a pair of small (often vestigial) setae (=SB1 setae) at middle near posterior margin or a pair of small tubercles at posterior margin medially (cf. Figs. 32, 55, 133, 141, 146,): sterna with or without discal setae, without glandular area. Hypomere of genitalia expanded or not expanded at apex (cf. Figs. 20, 77, 125).
