Djeboa multidentata K. Viets, 1911

( Figs. 41A–C )

Djeboa multidentata K. Viets, 1911: 494 .

Material examined: Type series: SMF, Cameroon; holotype male, K. Viets 43185; “ Kamerun, Bach bei Djebo, 6.6.1911, Damköhler leg., “1011”; paratype female, K. Viets 43187 “Cotype, Kamerun, Joh. Albrechts-Höhe, Bach am Wege Kumba Mundame, 2.10.1911, Damköhler leg. 1171“.

Further material: SMF K. Viets 43203, “ Kamerun, Ndvab-Fluß, 6.6.1913, 5555”, 1/0/0; K. Viets 43204, “Nyassa, Nkata-Bay, Fisch-Magen, Fryer coll. 7753”, 0/1/0.

General features: Dorsal shield oval (1.0–1.2), with medial depression; muscle scars with little pronounced thickenings, located anterior and posterior to the postocularia; colour pattern consisting of an anterior violet patch ( Figs. 41A–C ); gnathosomal bay Y-shaped, noticeably narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV reduced to a median angle; Cx-III and -IV with a series of longitudinal striae (four or five pairs on Cx-IV). Palp: P-1 with a dorsal seta; P-2 with concave ventral and convexly bowed dorsal margin; P-3 proximally thicker than distally, ventral margin slightly concave; P-4 slender, equally narrowing from the base to tip. Legs: I-L-6 L/H ratio 2.6, ventral margin strongly protruding.

Remarks: The original description of Djeboa multidentata was mostly based on a female from “Bach b. Djebo, 6.6.1911 ” while the male (same site and date) was described in a few lines and without figures (Viets 1911). An examination of material of Djeboa multidentata from the K. Viets collection shows that the female of slide 43204 surely does not belong to D. multidentata . The female on slide SMF 43187 labeled as cotype of D. multidentata agrees with the original description but as the palp is in situ and many characters are not visible, it is surely not the specimen described by K. Viets.

Distribution: Cameroon.
