- Anhoplocampa Wei, 1998: 14. Type species: Anhoplocampa fumosa Wei, 1998, by original designation.
Body length 7–11 mm. Clypeus flat, anterior margin emarginated (Fig. 10); malar space about as long as diameter of lateral ocellus; eyes small, distance between eyes at level of antennal sockets (toruli) 1.2–1.8 × greatest diameter of eye; supraantennal area distinctly protruding between antennal sockets; frontal area surrounded by strong carinae (Figs 2, 8, 16), upper margin of lateral fovea carinate; occipital carina absent; left mandible in lateral view with swollen base, narrowing to thin blade-like apex (similar to Benson 1958, fig. 380). Head weakly dilated behind eyes in dorsal view (Figs 2, 8, 16). Antenna long and slender, basal two antennomeres short, much broader than long, third antennomere clearly shorter than fourth antennomere, other flagellomeres subequal in length. Prepectus lanceolate, distinct, about 3 × longer than wide (Fig. 3); epicnemium narrow, strongly elevated, furrow between epicnemium and mesepisternum deep and broad in entire length, strongly curved in upper part across upper 0.10 of mesepisternum (Figs 3, 9). Inner tibial spur of front leg bifid apically, much longer than outer spur. Hind tibia with longitudinal furrow on outer side, tibial spurs short, 1.1–1.3 × apical breadth of tibia; hind tarsus about 0.8 × length of hind tibia; metabasitarsus about 1.1 × length of following 3 tarsomeres together; claw without basal lobe, inner tooth large, slightly shorter than or about as long as outer tooth (Figs 4, 11, 15). Forewing with a distinct dark band below pterostigma, vein R+M longer than cu-a, Sc slightly basad apex of vein 1M; vein 2r1 absent; vein 1M strongly convergent toward pterostigma with 1m-cu; cell 2Rs subequal to 1Rs in length and about 2 × as long as broad; 2m-cu joining cell 2Rs at basal 0.20–0.25; cell 1R1 about as long as broad, cell 2M longer than broad; vein 2A+3A meeting 1A at basal 0.3, basal anal cell closed; cu-a meeting cell 1M at about middle to basal 0.4 (Figs 1, 7, 14). Hind wing with cells Rs and M closed, anal cell closed, petiole of anal cell as long as width of anal cell and subequal to vein cu-a (Figs 1, 7). Cerci usually slender (Figs 5, 12, 17). Ovipositor sheath not longer than middle tibia, apical section of sheath with 3 processes in dorsal view, scopae distinct (Figs 5, 12, 17). Lancet with or without ctenidia, without stout annular setae, serrulae without denticles (Figs 6, 13, 18).

Anhoplocampa Wei, 1998 is similar to Trichiocampus Hartig, 1837 and Priophorus Dahlbom, 1835 but differs from those two genera by the very narrow and strongly elevated epicnemium; presence of a broad, deep furrow between the epicnemium and mesepisternum, strongly curved in the upper part of the mesepisternum; prepectus distinct; front wall and upper margin of the lateral fovea strongly carinate; left mandible in lateral view with a swollen base and a thin blade-like apex; vein R+M in forewing longer than cu-a; apical sheath with large scopae; cerci long and slender; forewing with a dark band below pterostigma; petiole of hind anal cell as long as width of anal cell; as well, in Trichiocampus and other Cladiini the vein 1M meets vein R close to the point where Rs+M meets R+M; vein 1M is far removed from that point in Anhoplocampa.
Anhoplocampa differs from Hoplocampa Hartig, 1837 by the much larger body; antenna longer than the abdomen with the scape and pedicel much broader than long; forewing with a dark band below pterostigma and vein 2r absent; petiole of anal cell of hind wing not longer than cu-a; left mandible in lateral view with a swollen base and a thin blade-like apex; epicnemium very narrow and strongly elevated, with a broad and deep furrow between the epicnemium and mesepisternum, strongly curved in the upper part of the mesepisternum; supraclypeal area strongly protruding between antennal sockets and distance between antennal sockets distinctly narrower than the inner orbit at the same level; frontal walls strongly carinate; and ovipositor sheath shorter than middle tibia and with distinct scopae.
Anhoplocampa is also somewhat similar to Renonerva Wei & Nie (Wei and Nie 1998) sharing the narrow and strongly elevated epicnemium with a deep and broad furrow between epicnemium and mesepisternum, but Anhoplocampa differs from the latter by the robust body and stout antenna; the distinctly emarginated clypeus; malar space about as long as diameter of middle ocellus; prepectus distinct; cerci not linear; forewing with a dark band below pterostigma, vein 2r1 absent, 2A+3A on forewing straight and the basal anal cell open; the hind basitarsus longer than the following three tarsomeres together; ovipositor sheath with distinct scopae; lancet not strongly reduced and lamnium not shorter than radix.
Anhoplocampa differs from Hemichroa Stephens, 1835 in the very narrow and strongly elevated epicnemium; presence of a broad, deep furrow between the epicnemium and mesepisternum, strongly curved in the upper part of the mesepisternum; front wall and upper margin of the lateral fovea strongly carinate; left mandible in lateral view with a swollen base and a thin blade-like apex; apical sheath with large scopae; forewing with a dark band below pterostigma, vein 2r1 absent and the middle petiole of anal cell on forewing shorter than vein R+M.
Anhoplocampa also shares some characters with Pristiphora Latreille, 1810, for example the bladelike mandibles and the apical sheath with distinct scopae. But Anhoplocampa differs from Pristiphora by the very narrow and strongly elevated epicnemium; presence of a broad, deep furrow between the epicnemium and mesepisternum; front wall and upper margin of the lateral fovea strongly carinate; the forewing with a dark band below pterostigma, the vein 2A+3A curved up and meeting 1A and therefore the basal anal cell closed.
