In this section
5th sternite The 5th ventral plate of the 5th abdominal segment, generally square but often highly modified in male tachinids  

A
Abdomen The posterior major section of invertebrates  
Abdominal Discal Setae Central setae on abdominal tergites in front of marginal setae.  
Abdominal Tergites Dorsal abdominal segments  
Anatergite A tergite (plate) of the mesothorax (middle thorax) between the scutellum and the halter located under the calypter in tachinidae  
Antenna 3 segmented in tachinidae bearing a 3 segmented arista  
Antennal Grooves Paired grooves on the face often separated by a carina (facial carina)  
Apical Scutellar Bristles/Hairs A pair of seate or hair situated at the apex of the scutellum  
Arista 3 segmented hair like structure arising from the postpedicel  
Aristomere A segment of the arista (3 segments)  

B
Bm-Cu Basal medial-cubital cross vein  

C
Calyptra Upper and lower calyptra are lobes at the posterior base of the wing  
Costal Bristles Bristles along the anterior margin of the wing situated on the costal vein  
Cs3 Coastal section 3 on the anterior wing margin  
CuA1 Cubital wing vein.  

D
Dm Discal medial wing cell  
Dm-Cu Discal medial-cubital cross vein  

E
Eye Visual sensory organ at the lateral surface of the head  

F
Face Or Facial Plate The area defined dorsally by the antennal sockets, ventrally by the lower facial margin and laterally by the facial ridge  
Facial Carina Longitudinal keel separating the antennal grooves  
Facial Ridge Small sclerotized longitudinal plate located lateral of the face  
Femur Subbasal segment of the leg  

G
Gena Cheeks, below the eye  

H
Head First major section of the invertebrate body, usually bearing the eyes and antennae  

K
Katepisternum More or less triangular plate situated between front and middle coxa  

M
M Media – third longitudinal wing vein  
Marginal Setae Setae situated at the posterior margin of abdominal tergites  
Midfemur The femur of the middle leg  

O
Outer Fronto-Orbital Bristles Bristles located dorsally between the eye and the inner fronto-orbital bristles  

P
Palpus (Palpi) Structure of the maxilla situated at the base of the proboscis  
Parafacial Area between the eye and the facial plate  
Pedicel 2nd antennal segment after the scape  
Peristomal Bristles Bristles or setae along the vibrissal angle usually much smaller than the vibrissae  
Petiole Petiole is the stem-like extension arising from the wing cell r4+5  
Post Pedicel 3rd antennal segment following from the pedicel  
Posteroventral Posterior and ventral of .....  
Postmetacoxal Area The area between the hind coxae, ventrally of the abdominal attachment, this area maybe sclerotized or membranous  
Presutural Intra-Alar Seta The intra alar setae that are located posterior of the dorsal suture of the thorax  
Proboscis The mouthparts  
Prosternal Membrane Membrane on either side of the sclerotized prosternum  
Prosternum Ventral sclerotized plate between the front coxae  

R
R-M Radial-medial cross vein  
R1 Wing vein  
R2-3 Radial wing cells  
R4-5 Radial wing cells  

S
Scutellum The posterior part of the mesothorax  
Seta (Setae)    
Stem Vein Basal section of the radius vein r1  
Subcoastal Joint Where the subcosta sc joins the costa between cs1 and cs2 at the anterior wing margin.  
Subcranial Cavity = oral cavity, the opening on the ventral aspect of the head, incorporating the mouthparts  
Subscutellum Convex, cushion-like located posteroventrally of the scutellum. a defining characteristic of tachinidae  

T
Tarsus The distal segment of the leg divided into 5 segments (tarsomeres)  
Tergite The dorsal plate of each abdominal segment  
Thorax The middle section of an insects body  
Tibia The middle section of the leg between femur and tarsus  

V
Vertex The upper part of the head  
Vibrissae One or rarely more outstanding, forward and inclinate directed bristles at the foremost point of the vibrissal angle  
Vibrissal Angle Ventral part continuing from the facial ridge
