Minute discoidal pores few, each 2 µm in diameter, scattered on body surface. Oral-collar tubular ducts of 2 sizes, larger each 7–11 µm long, 4–5 µm wide, present in rows on each abdominal segment as follows: 14 on I; 8 on II; 19 on III; 16 on IV; 25 on V; 28 on VI; 20 on VII; 14 on VIII; also scattered on thorax plus a few on head; smaller ducts few, each 7–11 µm long, 2.5–3 µm wide, present medially on posterior 3 abdominal segments,.

Venter. Body setae slender, each 10–85 µm long, longest setae medially on head; apical anal lobe setae 210– 220 µm long. Multilocular disc pores each 7.5–9.0 µm in diameter, present in rows or bands on posterior abdominal segments (IV–VIII+IX): 4–6 pores on segment IV, 15 on segment V, 37 on segment VI, 38 on segment VII, 36 on segments VIII + IX. Quinquelocular pores each 4–5 µm wide, scattered throughout. Trilocular pores restricted to around spiracle atrium, each 2.5–3.0 µm in diameter. Minute discoidal pores each 2 µm in diameter, scattered throughout. Oral-collar tubular ducts each 7.5–10 µm long, 2.5–3.0 µm wide, in rows across most abdominal segments plus a few on thorax; distributed as follows: 2 on abdominal segment I; 4 on II; 11 on III; 12 on IV; 28 on V; 26 on VI; 28 on VII, and 15 on VIII.

Comment. The adult female of Heterobrevennia kozari Kaydan is unique for a species in the Heterococcus group in having the following combination of character states: (i) many quinquelocular pores on both dorsum and venter, (ii) hair-like tarsal digitules, (iii) ventral multilocular pores present on posterior abdominal segments, (iv) translucent pores present on coxa, femur and tibia, (v) five pairs of cerarii, and (vi) many oral-collar tubular ducts throughout the dorsum. The most unique characters are the presence of 5 cerarii and pores on hind coxa.

In having most of the above mentioned features, H. kozari resembles H. opertus but differs in having (characters of H. opertus in brackets): (i) only 5 pairs of cerarii (7), (ii) many trilocular pores scattered throughout dorsum (trilocular pores on dorsum few, generally restricted to the posterior abdominal segment, cerarii and ostioles), (iii) transcluent pores present on hind coxa (absent), and (iv) dorsal multilocular pores present only on abdominal segments VI and VII (scattered all over body). H. kozari is also similar to H. gullanae Kaydan , described above, but differs in having (characters of H. gullanae in brackets): (i) 5 pairs of cerarii (6), (ii) transcluent pores on coxa (absent), (iii) one size of oral-collar tubular ducts on dorsum (two sizes on posterior abdominal segment), (iv) dorsal multilocular pores restricted to abdominal segments VI and VII (also present in two group on head), and (v) antennae 9 segmented (8, rarely 7).

Etymology. The new species is named in honor of Dr. Ferenc Kozár (Department of Zoology, Plant Protection Institute, Hungarian Academy of Sciences, Budapest, Hungary), who has made valuable studies on many aspects of coccidology throughout the World.
