GV5 Caledomina sp. 1 – Espeland & Johanson 2010: 2116.

Diagnosis

Caledomina kohensis is distinguished from all other species in the genus by the almost straight sternal process of sternite IX and the dorsal branch of the superior appendage with a row of spines on the mesal face.

Etymology

Kohensis, named after the village Koh near the type locality.

Description

WINGS. Wing length unknown as body is lost.

GENITALIA. Total length about 0.5 mm. Segment IX divided into pair of strong, anteriorly rounded ridges in lateral view ( Fig. 11 View Figs 11–15 ); sternite IX originating from anterior ridge below mid-height; broadening gradually posterad into sharply triangular plates with postero-dorsal sternal process ( Figs 11, 13 View Figs 11–15 ); smooth. Sternal processes slender, almost straight, with large apical spine nearly one-fourth as long as sternal process ( Figs 11, 13 View Figs 11–15 ); oriented posterad along their length in ventral view ( Fig. 13 View Figs 11–15 ); reaching slightly beyond point of bifurcation of superior appendages ( Fig. 11 View Figs 11–15 ). Tergite IX horseshoe-shaped in lateral view ( Fig. 11 View Figs 11–15 ), anterodorsal corners almost straight, oriented antero-dorsally; central part with long setae on lateral faces; in dorsal view ( Fig. 12 View Figs 11–15 ) with anterior-most part fused mesally, forming an undulating band; posterior part divided into broad branches ( Fig. 11 View Figs 11–15 ). Tergite X small, membranous, present above posterior apex of tergite IX in lateral view ( Fig. 11 View Figs 11–15 ); in dorsal view divided into two lobes associated with branches of tergite IX; with posterior and mesal setae ( Fig. 12 View Figs 11–15 ). Superior appendages large; each divided into posterior dorsal and ventral lobes ( Fig. 11 View Figs 11–15 ). Dorsal lobes oriented posteriorly, smooth except with series of long spines oriented mesally ( Fig. 12 View Figs 11–15 ). Ventral lobes originating gradually from anterior part of each tergite IX; nearly straight along their length; basal half of ventral face covered by minute spines ( Fig. 13 View Figs 11–15 ); each with posterior half slightly curving mesally and partly overlapping near apices; covered with setae; slightly exceeding dorsal lobe in length ( Fig. 11 View Figs 11–15 ). Inferior appendages completely fused into small, mesal process, connected to central part of sternite IX by sclerotized ridges ( Fig. 11 View Figs 11–15 ); dorsal margin slightly sigmoid; ventral margin convex; apex long, narrow in lateral view ( Fig. 11 View Figs 11–15 ); in ventral view ( Fig. 13 View Figs 11–15 ) with broad basis; narrowing strongly at one quarter its length, apex smooth, bifurcated. Phallic apparatus ( Figs 14–15 View Figs 11–15 ) with weakly developed ventrally pointed lobe ( Fig. 14 View Figs 11–15 ); irregularly tube-shaped; dorsal margin strongly narrowing at anterior one-third; posterior apex membranous.
