Additional functions, like defense, brood care, and male-male competition, modified the mouthparts in some insects. Their head capsule is flattened in a posterior-anterior direction and very similar among the studied species. Hence together with labrum of head capsule and hypopharynx, these appendages copmrise the mouth parts of the cockroach. The division of the species of this genus into two groups, "kehleri" and "farrani", is proposed, based on marked differences in the type of the rostrum, in the mandible's gnathobase, in the maxilla 2 and in the legs, especially the fifth leg. The maxillae, labium and hypopharynx combine together to form a sucking proboscis. This pressure is generated in the stipes which is associated with each galea. Labium: It is a long, flesh, flexible and unpaired structure with groove called labial groove along its mid dorsal side. Phylogenetic approaches covering all organ systems including analyses of potential functional or developmental convergence are still pending so that the Palaeoptera problem has to be considered an open question in insect systematics.

What are the functions of labrum and labium in the insect mouthparts? The hypopharynx is the only part that is not a true seg-mental append-age but rather a modified part of Shows movement of mouth structures in Madagascar hissing cockroach. The head is bent downward, and the mouthparts point backward instead of forward or downward as is the case in most other insects. The proboscis is divisible into rostrum, haustellum and labellum. these mouthparts help the cockroach to bite and chew on hard food stuff. Mandibles are absent. The cockroach has a biting and chewing type (mandibulate or orthopterus type) of mouth parts. The details of the labrum, mandibles, maxillae, labium, and hypopharynx, characteristic of different suborders of Blattodea and some families of Blaberoidea, were revealed.

This type of mouth part also found in silverfish, termites, earwigs, beetles, some Hymenopterans and caterpillar of lepidoptera. The basic structure of mouthparts remains the same. The right mandible is very constant in shape, while the number of distal incisivi in left mandibles varies among species. This type of mouth part also found in silverfish, termites, earwigs, beetles, some Hymenopterans and caterpillar of lepidoptera. Mouthparts of insects are modified cephalic appendages. These help in 'biting and chewing' its food. â¢ The mouth parts consist of labium, labrum-epipharynx, hypopharynx, mandibles & maxillae â¢ Mouth parts:- â Labium:- â¢ The labium is modified to form a long, straight, fleshy tube called proboscis. The saliva is injected into the blood through hypopharynx. Mouth Parts of cockroach 3D Model available on Turbo Squid, the world's leading provider of digital 3D models for visualization, films, television, and games. Potential apomorphies for Blat-todea in the cephalic area include the absence of the median ocellus, the bipartite condition of M. verticopharyngealis (0ph1) and of M. hypopharyngosalivaris (0hy12), and the presence of oesotendons. They belong to the family Neanuridae and family Pseudachorutidae respectively. This is a modified appendage of the 3 rd body segment. The mandibles in these flies are useful in slicing the skin and then the blood which is exposed is sponged up. Analyses of the accumulation of signal across gene partitions showed that signal accumulates gradually.
