Meron: in Neuroptera, a sclerite posterior to the coxa and below the epimeron: corresponds to the trochantine in Lepidoptera.
Platelet: a little plate or sclerite of chitin in a membrane.
Metinfraepisternum: in Odonata; the sclerite just above base of 3d coxa; below metepisternum and before metepimeron.
Axillary lobe: the sclerite covering the base of the wing in Diptera; see also alula and posterior lobe.
Subglossa: in Odonata; a sclerite between the two halves of the mentum (Graber): is really the true mentum.
Epilabrum: a sclerite at each side of the labrum: specifically applied in myriapods.
Prosternum: the fore-breast: the sclerite between the fore-legs.
Mesepimeron: in Odonata: the sclerite between humeral and first lateral suture.
Mesinfraepisternum: a sclerite formed between propleuron, mesepisternum, mesepimeron and second coxa.
Metasternal episterna: sclerite situated on each side of the metasternum, immediately behind the mesosternum epimera.
