Fidicina mannifera (Fabricius)
Body dark brown in coloration, curved in lateral view, legs and ventral region covered with many bristles (
Fig 1e
).
Head. In dorsal view, crown including the eyes, about four times wider than long; slightly wider than the margin anterior of the pronotum (
Fig 1f
). In ventral view, rostrum reaching posterior coxae.
Thorax. In dorsal view, pronotum and mesonotum with similar lengths, metanotum very short in comparison with the pronotum and mesonotum (
Fig 1f
). Wing cases developed, reaching abdominal segments (
Fig 1e
). In the foreleg, femur with a long and sharp posterior tooth, slightly bent forward, about two times longer than the width of its base, small and sharp accessory tooth and a strong intermediate tooth present; femoral comb usually with seven teeth, the first one wide and projected forward (femoral formula 2-1-7) (
Fig 2d
). Tibia arched, flattened laterally; apical tooth long; blade of the tibia with teeth; tip of blade of tibia developed and separated from the apical tooth by a strong incision (
Fig 2d
). Tarsi developed, folded over the inner surface of the tibia, each two segmented, with the apical tarsomere much longer and fitted with a pair of claws of unequal sizes. In the mid legs, tibia with many protrusions along the outer side (
Fig 5b
). In the hind legs, apex of tibia with five spines (
Fig 4c
). Tarsi two segmented, the apical ones much longer and fitted with a pair of claws of unequal sizes.
Abdomen. Size varies according to the development of the nymph,sometimesreduced, withthedistalextremityofhind wing almost reaching the apex of abdomen, or elongated, with the distal extremity of hind wing reaching the middle of abdomen. Female: 8th and 9th sternites with two sharp posterior marginal protrusions.Male:10th sternite with two strong projections close to the anterior margin (
Fig 3d
).
