From tergal meaning 'dorsal'.
In Diptera the upper (dorsal) sclerite of an abdominal segment.
In descriptions and keys tergites are numbered (from the base of the abdomen starting at 1) and often abbreviated. An example:
"TG1 and T8 sparsely brown pruinose. T2-T4 over 1.5 times more long than wide, remaining tergites shorter and wider. T8 visible only on right side. Tergites short setose except TG1, lateral margins of T2 and T3 with long setae." (Neohybos cinereus; Hybotidae).
"Opposite" of sternite a ventral sclerite.
