FI4 Caledomina sp. 2 – Espeland & Johanson 2010: 2116.
Diagnosis
Caledomina paniensis is distinguished from other species in the genus by the presence of a pair of sternal processes of sternite IX reaching about as long posteriorly as the inferior appendages.
Etymology
The specific epithet is derived from the type locality, Mount Panié.
Type material
Holotype
NEW CALEDONIA: ♂, Province Nord, Mt Panié, river below waterfall, 20°35.864' S, 164°49.780' E, 350 m, loc #16-2001, Malaise trap, 22–28 Nov. 2001, Johanson, Pape and Viklund leg. (MNHN, DNA voucher: NHRS-FI4).
Description
WINGS. Fore wing length 2.2 mm, hind wing length 1.6 mm.
GENITALIA. Total length about 0.5 mm. Segment IX divided into pair of strong, anteriorly pointed ridges in lateral view (Fig. 1); sternite IX originating from anterior ridge at mid-height; broadening posterad into pair of nearly parallel-sided plates with postero-dorsal sternal process (Fig. 1); smooth, except few ventral setae. Sternal processes short, slender, slightly curving dorsally, each with large apical and subapical spine nearly as long as sternal process (Figs 1, 3); orienting posterad along their length in ventral view (Fig. 3); almost reaching point of bifurcation of superior appendages (Fig. 1). Tergite IX Y-shaped in lateral view (Fig. 1), anterodorsal corners strongly curving anterad before bending posterad at apex; with long setae on lateral faces; in dorsal view (Fig. 2) with anterior-most part fused mesally; posterior part divided into tapering branches. Tergite X membranous, present above posterior apex of tergite IX in lateral view (Fig. 1); in dorsal view divided into two lobes associated with branches of tergite IX; with minute setae along mesal margins (Fig. 2). Superior appendages large; each divided into posterior dorsal and ventral lobes (Fig. 1), with setae basally of bifurcation (Figs 1–2). Dorsal lobes smooth, except with long row of hook-like spines oriented ventro-mesad (Figs 1–2). Ventral lobes nearly straight along their length; ventral margin with minute spines; posterior apex narrowly rounded, covered with small setae; slightly exceeding dorsal lobe in length (Fig. 1). Inferior appendages completely fused into small, mesal process, connected to central part of sternite IX by vaguely defined sclerotized ridges; dorsal margin slightly sigmoid; ventral margin convex except curving at apex; apex long, narrow in lateral view (Fig. 1); in ventral view (Fig. 3) with broad basis; narrowing slightly at one quarter its length, apex smooth, bifurcated. Phallic apparatus without processes (Figs 4–5); tube-shaped; dorsal margin weakly narrowing at anterior one-third; posterior apex membranous.
Remarks
This species was referred to as “FI4 Caledomina sp. 2” in Espeland & Johanson (2010).
