Dicerura foliicola Mamaev, 1968

Figs 13–15

This Far East Russian species is known only from the type series, which consists of two specimens of each sex reared from larvae (Mamaev 1968). With a male body length of two millimeters, D. foliicola is one of the smaller species of Dicerura. The holotype male, which we studied here, is a pale, yellowish specimen with poorly contrasting genitalia; it is therefore possible that we missed inconspicuous substructures of the tegmen or ejaculatory apodeme.

Diagnosis. Characteristic of the gonocoxites is a rounded, asetose protrusion at the base of the ventral emargination, which has a glabrous border on either side (Fig. 13, ↓1). The medial gonocoxal bridges, which are

slightly protruding, are conspicuously densely setose. The gonostylus is characterized by the large medial lobe, which is strongly bulging (Fig. 13, ↓2), and the small, narrow apex, which is densely setose (Fig. 13, ↓3). The apical

fork of the ejaculatory apodeme consists of two lance-shaped rami, which are broader than in other species of Dicerura (Fig. 15, ↓4). The tegmen ends in a long, sharp point, which apparently is not an artifact of preparation

(Fig. 15). The ninth tergite, whose outline is broad-subtrapezoid, is very slightly concave and densely

microtrichose posteriorly (Fig. 14).

Material examined. Holotype male (specimen no. P-Di0137 in ZMUM), with the data as specified in the

original description (Mamaev 1968).
