Batracobdelloides moogi Nesemann et Csányi, 1995 (Hirudinida: Glossiphoniidae): Morphometry and structure of the alimentary tract and reproductive system

Abstract

Batracobdelloides moogi, the species representing the afroasiatic genus, is very poorly known for its biology and anatomy. This species was described on the basis of a small group of samples from south-western Europe. This study presents a morphological analysis and description of the structure of the alimentary tract and reproductive system. Biometry and external morphology were analyzed on 96 individuals and the anatomic structure on 40 individuals. The average length of the examinated specimens was 9.81 mm and the average weight was 0.056 g. The length of proboscis ranged from 2.5 to 4 neurosomites. Lengths of each ovary ranged from 1.5 to 3.5 neurosomites. Lengths of left and right sperm ducts ranged from 0.5 to 2.5 neurosomites. Correlation between the length of sperm ducts and their coiling was recorded.

“…The external morphological characters (number and position of eyes, annulation, color, papillation, position of genital pores, and body size) 70 were examined on specimens of the new species and related taxa. Body measurements for the new leech species were performed using a stereomicroscope Leica M165C (Leica Microsystems GmbH, Germany) equipped with an ocular-micrometer as follows: body length (BL), body width (BW), width of anterior sucker (AW), and width of posterior sucker (PW).…”

To study the reproductive and digestive systems, leeches were dissected using a standard approach 70 . The images of specimens and their morphological and anatomical details were taken with stereomicroscopes Leica M165C (Leica Microsystems GmbH, Germany) and Zeiss Axio Zoom.V16 (Carl Zeiss AG, Germany).…”
