Description
FIGURE 6. Comparison of different species of the Poecilimon affinis/ornatus-group [cluster-analysis, distance metric is Euclidean distance, single linkage method (nearest neighbour) based on population means]. Populations studied: P. affinis (RO—Mehadia, Romania; SR—eastern Serbia), P. a. dinaricus (Durmitor), P. ornatus (Mt. Stivo, Italy; Obir, Austria; song parameters partly after Heller 1988), P. pseudornatus (Durmitor; Tara Mt.), P. nonveilleri (Durmitor), P. rumijae (Mt. Rumija, Montenegro). A, cluster using the morphometrical data "scapus: fastigium verticis x 100" (of male and female), "pronotum length: width at apex x 100 (of male), "postfemur length of male and female", "ovipositor length", Euclidean distance 0–20; B, cluster using data of the stridulatory vein "number of stridulatory teeth", "change from small to large teeth (lower and upper values)", "presence of a bump on the stridulatory vein" (presence = 100, absence = 0), Euclidean distance 0–100; C, combination of A and B, Euclidean distance 0–50; D, cluster using song characteristics "syllable duration", "duration of the pronounced final part of the syllable (if any)", "main frequency below 20 kHz", Euclidean distance 0–100.
