Diagnosis. Physopeltinae are principally diagnosed by the intersegmental sulci between abdominal sternites being deeply sinuated (S-shaped). In Larginae, the intersegmental sulci between sternites are straight.
Comment. The genera of Largidae are quite diversified in their external morphology and quite uniform in genitalic morphology, so no additional clear-cut diagnostic characters for the subfamilies can currently be recognized.
Key to the tribes and genera of Physopeltinae
1 (2) Male abdomen much prolonged, in large males hemelytra not reaching mesotergite IV, in smaller males hemelytra reaching middle of mesotergite V. Female abdomen not elongated, in large females not reaching apex of abdomen, in smaller females reaching apex of abdomen. Antennae very long, in large males antennomere 1 reaching apex of membrane, in smaller specimens reaching only apex of clavus. Very large species, body length: males 28.5–62.5 mm, females 26.0–36.0 mm. Oriental Region. ...................................... Lohitini: Macrocheraia Guérin-Méneville, 1835
2 (1) Male abdomen never prolonged.Antennae much shorter. Small to large species, body length 5.2–20.0 mm. ............................................................................................... 3
3 (6) Profemora ventrally without longitudinal furrow. .................................................. 4
4 (5) Profemora ventrally with denticles on its entire surface (Figs 83, 97). Body dorsoventrally rather flat. Lateral margins of callar lobe forming a low, rounded carina. Procoxa without any tubercle (Figs 81−82). Body covered with short, adpressed hairs. Body length: males 15.5–19.6 mm, females 16.0–18.9 mm. Afrotropical Region. ................................................................. Kmentiini trib. nov.: Kmentia gen. nov.
5 (4) Profemora ventrally with two rows of denticles separated by a flat surface; anterior row of denticles apically with two long spines, posterior row in apical half with four shorter spines (apicalmost one being longest). Body not flattened. Lateral margins of callar lobe flattened, forming high and sharp carina directed horizontally. Procoxa ventrolaterally with a single small tubercle. Body covered with dense and long erect hairs. Body length: 20 mm. Male unknown. Indonesia: Sulawesi. ........................... ..................................................... genus incertae sedis: Wachsiella Schmidt, 1931
6 (3) Profemora ventrally with a longitudinal furrow. Physopeltini Hussey, 1929 ....... 7
7 (8) Callar lobe of pronotum strongly gibbose, posteriorly strongly constricted and markedly demarcated from pronotal lobe. Body length 8.6–8.8 mm. Australia, New Guinea. ......................................................................... Taeuberella Schmidt, 1932
8 (7) Callar lobe of pronotum neither strongly gibbose nor markedly demarcated from pronotal lobe. .......................................................................................................... 9
9 (10) Head short, positioned much lower than strongly gibbose dorsal surface of callar lobe (see in lateral view). Lateral margin of pronotum broad. Males pterygodimorphic, macropterous or brachypterous. In macropterous morph, all coxae provided with denticles. Body length 12.7–13.4 mm. Female unknown. ... Jindraia Stehlík, 2006
10 (9) Head not shortened and situated about the same level as pronotum. ................... 11
11 (12) Lateral margins of pronotum widely explanate, elevated above pronotal surface. Callar lobe weakly gibbose in both sexes. Macropterous. Large species, body length 14.8–21.2 mm. Oriental Region, New Guinea. ............................. Iphita Stål, 1873
12 (11) Lateral margins of pronotum narrow. Callar lobe strongly to weakly gibbose. Usually smaller species. ..................................................................................................... 13
13 (14) Larger, body length 9.5–20.0 mm. Callar lobe strongly gibbose in male, less gibbose in female (different among subgenera). Macropterous. Stridulatory organs (when present) on coxa and trochanter of fore leg. Afrotropical, East Palaearctic, Oriental and Australian Regions. .................................. Physopelta Amyot & Serville, 1843
14 (13) Smaller, body length 5.2–8.7 mm. Callar lobe equally elevated in both sexes. Often pterygodimorphic, with macropterous and brachypterous morphs. Stridulatory organs (when present) on lateral margins of pronotum and corium. Oriental and Australian Regions. ........................................................................
