posterior margin slightly angular. Anterior body 
margin concave. Cauda well set off from body, 
with a median cleft. Petiole chisel-shaped, with 
convex lateral margins and a straight posterior 
margin (Figure 52). Posterior margin of cauda 
slightly indented. L3 on obtuse humps; D4 on small 
humps (Figure 53). Genital plates bowed, narrow, 
extending onto lateral sides of body (Figure 51). 
Gonopore 58 long. Lengths of PI-V: 24, 48, 65, 72, 
34; PII with two setae on medial side (one large 
and one small seta) (Figure 54). Lengths of I-leg-4- 
5: 103, 106, 122; lengths of IV-leg-4-6: 146, 113, 127. 
IV-leg-4 with a long, pointed spur. 
Female 
Body 892 (844-931) long and 795 (737-844) wide. 
Body oval-shaped, truncated posteriorly and with 
a straight posterior margin (Figure 55). Capitular 
bay V-shaped. Medial margin of CX4 larger than 
medial margin of CX3. Distance of CX4 as large as 
one genital valve. Gonopore 92 long; genital valves 
with large chitinous patches. Genital plates narrow, 
geniculated. Lengths of PI-V: 34, 58, 36, 82, 38; PII 
with 3 setae on medial side. Lengths of I-leg-4-6:

Remarks 
Females are more difficult to separate from 
related species, e.g. A. madaraszi Daday. The female 
of the new species has geniculate genital plates, but 
most characteristic is the truncated posterior body 
part. 
Etymology 
The species is named after the type locality.
