There are two main parts to the labium: the proximal postmentum, closely connected to the posteroventral surface of the head and sometimes subdivided into a submentum and mentum; and arthropod leg, or the origin of the labrum and other non leg-like appendages to a palp (some crustaceans) or completely absenl (some crusta- ceans, all cases the mandibulates are not monophyletic (e.g., Friedrich and. Tautz, 1995; Wills These modifications allow insects to occupy almost every ecological niche, use a staggering variety of food sources, and possess diverse lifestyles. This article describes the basic insect body and some of the major variations that it can take; in the process it defines many of the technical terms used to describe insect The mandibles of P. Kuandianensis are similar to those of P. Paradoxa, but much narrower and longer than those of Brachypanorpa [18,31]. The triangular pyramid-shaped lacinia with dense different spines is observed at ultrastructural level for the first time in Panorpodes, with its structure quite similar to that of Sinopanorpa [19].

Insect morphology is the study and description of the physical form of insects. In mandibulate mouthparts, the labium is a quadrupedal structure, is called the postmentum. This may be subdivided into a proximal submentum and a distal mentum.
