Description of the nymphs of Tenagobia (Incertagobia) incerta Lundblad 1929 and Tenagobia (Schadeogobia) schadei Lundblad 1929 (Hemiptera: Heteroptera: Micronectidae), with emphasis on morphometry and chaetotaxy

The three last nymphs of Tenagobia (Incertagobia) incerta and the egg and the third and fifth nymphs of T. (Schadeogobia) schadei are described and illustrated for the first time, with emphasis on the morphometry and chaetotaxy of selected structures. Comparisons with the nymphs of T. (Fuscagobia) f...

The egg of T. schadei has a very long stalk like those of T. selecta and T. fuscata, and it differs from the ones of T. pulchra and T. incerta, which have a short stalk. The nymphs of Tenagobia share the presence of 1 dorsal abdominal scent gland on each of the segments III-V, and the absence of spines on the metafemur, except those on postero-apical surface which are present. The nymphal characters most useful in identifying nymphs III-V of Tenagobia are: the body length, the head width, the grade of development of the wing pads, the number of setae on the inner surface of the protibiotarsus, spines on the anteroventral and posteroventral surfaces of the mesofemur, lanceolate setae on the anterior surface of the metatibia, and spines on the metatibial comb. The nymphal characters most useful in identifying species of Tenagobia are the head width, the number of setae on the dorsal row of the protibiotarsus, and spines on the anterior surface of the mesotibia. © 2010 · Magnolia Press.
