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


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)  


Bm-Cu Basal medial-cubital cross vein  


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.  


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


Eye Visual sensory organ at the lateral surface of the head  


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  


Gena Cheeks, below the eye  


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


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


M Media – third longitudinal wing vein  
Marginal Setae Setae situated at the posterior margin of abdominal tergites

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  


Tarsus The distal segment of the leg divided into 5 segments (tarsomeres)
