Diagnosis
Redundant, genus monotypic.
Etymology
The species epithet is a Latin adjective meaning ‘crowned’ and refers to the antlerlike telomere.
Material examined (total 1 ♂)
Holotype TANZANIA • ♂; Uluguru Mts, Lupanga, West; 1900 m a.s.l.; 1 Jul. 1981; M. Stoltze and N. Scharff leg.; litter; NHMD 621765.
Description (male)
SIZE. Length 51 mm, diameter 3.1 mm, 58 podous rings, no apodous rings in front of telson.
COLOUR. Quite faded after 37 years in alcohol. Head pale yellowish brown, except for dark brown band between eyes, dark band extended anteriad along antennal socket and in middle. Antennae and legs pale yellowish brown. Collum marbled brown with dark brown margins, dark margins expanded in midline, especially anterior margin. Body rings: anterior ⅔ of prozonites whitish, posterior ⅓ of prozonites and anterior ½ of metazonite dark brown, posterior ½ of metazonites amber. Telson pale yellowish white, except for dark brown anterior ½ of preanal ring.
SUPRALABRAL SETAE. Indistinct.
MANDIBULAR STIPES. Distal margin bilobed.
ANAL VALVES. Each with a small dorsal spine and a slightly produced ventral ‘corner’ margin not raised, with three sessile setae.
LIMBUS (Fig. 60D). Margin with slender, smooth lobes, more than twice as long as broad.
LEGS. With postfemoral and tibial pads on post-gonopodal legs, decreasing in size and eventually disappearing on posterior legs.
FIRST PAIR OF LEGS (Fig. 60E–G). Prefemoral lobes almost semicircular in ventral view. Three coxosternal setae (CXS) close to lateral margin of coxosternum, well separated from prefemoral lobes. Prefemora with a few peglike mesapical sensilla (APS), numerous peglike lateral sensilla (LPS) distributed over large part of prefemoral lobes.
STERNUM 9 (Fig. 60H). Triangular with rounded corners.
GONOPOD COXA (Fig. 60A–C). Roughly parallel-sided, posterior-lateral surface deeply concave (Fig. 60A, double-headed arrow). Proplica (PP) with straight mesal margin, ending in small proplical lobe (hidden under pf on Fig. 60B); distal to lobe with subrectangular, shallowly bilobed mesad flange (pf). Metaplica (MP) with roughly straight mesal margin; distal margin also straight, laterally produced in almost horizontal, pigmented spine (LCS), basally with large, almost right-angled metaplical flange (MF).
GONOPOD TELOPODITE (Fig. 61). Arculus 90°. Torsotope (TT) simple, compact, no post-torsal spine. Posttorsal narrowing (PN) pronounced, quite long. Solenomere (SLM) very long, longer than telomere, whiplike, with a long, straight, basal spine (BSS) at right angles to main stem of solenomere, otherwise without any outgrowths, smoothly curving in concavity of telomere, then smoothly curving back. Telomere (TM) overall a single boat-shaped lamella, basally forming a flange (btf) subtending BSS, mesally forming large, semicircular lobe (tml), distally narrowing, ending in complicated, irregularly branched structure resembling a set of antlers (Fig. 61A, thick arrow).
Remarks
Uncodrama coronata gen. et sp. nov. is remarkable for its elaborate, antlerlike terminal telomeral lobe. Many odontopygids belonging to various genera have distally spinose telomeres, e.g., some Chaleponcus dabagaensis group members (Enghoff 2014), Kompsoprium calcaratum (Attems, 1935), Spinotarsus johnsensis Kraus, 1960, S. rhodesianus Kraus, 1960, S. silvicolens Kraus, 1960, Patinatius bidentatus simulator Kraus, 1966. The new species, however, is by far the most elaborate in this respect, followed at a distance by K. calcaratum (Attems 1935: fig. 107).
