Deuterocopus tengstroemi Zeller, 1852


Fletcher, 1910[1] redescribed the species, including a translation of Zeller's[2] original description:

Deuterocopus tengstroemi, Zell.

The following is a translation of Zeller's original description :—

"Body and wings ferruginous, cilia of the latter spotted with fuscous; third segment of hind wing with black scaling in middle of dorsum and around apex (♂, ♀).

"Size of a small Pt. obscurus. Body and wings rust-yellow, the former rather shining and somewhat browned on the thorax. Antenna in ♀ only half-length of forewing, moderately thick, ringed with white and brown, basally white above; antenna of ♂ somewhat longer, less ringed, above dilated and with broader white markings; terminal joint somewhat thickened, apex acuminate. The hairs on the hinder margin of the head erected and inclined forwards. Palpi as long as the head, moderately thin, horizontal; the terminal joint pointed, white above, before the tip and on the underside yellow-brown. Haustellum yellowish, as long as the thorax. Pectus white-spotted on the side. Venter white, the edges of the first two segments with small rust-yellow bands enlarged laterally. Forelegs rather shining on the femora and base of tibia; the end of the tibia is thickened knottily with unequally-long, very plentiful, rust-brown scales; out of the knots project the long whitish spurs, blackish on one side; the tarsi are whitish above, the first joint thickened apically with scales and black, the three following not densely scaled beneath, the two last suffused with black. In the second pair of legs the tip of the tibia is only slightly thickened, the tarsi whitish blackened at the tip. [N.B.— By some error Zeller has evidently transposed the descriptions of the fore- and mid-legs, and this must be borne in mind when reading the above translation. — T.B.F.] In the posterior legs the tibiae are extraordinarily thick, with three thickenings; the weakest is near the base ; the second is strong, ruffled up in the shape of a funnel, sprinkled with brown at its base, and is situated at the root of the first pair of spurs; the third is still stronger and longer, is likewise ruffled up and thickly suffused with blackish and is situated at the extremity of the tibia: the upper pair of spurs reaches somewhat beyond the extremity of the tibia and is thickened with hairs, rusty-yellow on one side, on the other white and blackish- brown at the tip; the second pair of spurs is as long as the first two tarsal joints and is also hairy on one side, rusty-yellow, black at the root and in the middle, and at the tip white with a small black spot. The first three tarsal joints are rusty-yellow, the first with a somewhat weak apical hair-funnel, the second with a weaker hair-funnel white apically, the third with a still weaker brown hair-funnel; the last two joints are black.

"Forewings 2 1/2 to 2 1/3 lines long, moderately slender; the fissure stands somewhat separated. The first segment, which is almost half as long as the wing, is brown and strewn longitudinally with blackish scales. A bright yellowish transverse streak cuts off the beginning of the darkening to a narrow bar. The costal cilia are bright rust-yellow with three black longitudinal streaks at equal distances up to the apex. The yellowish inner-marginal cilia are blackish at the mouth of the fissure; between these places and the black streak coming out to the tip of the wing the fringes are light-yellow on the blackish edge-line. The second segment is browned on its outer three-fourths, darker than the first segment; at its middle it splits into two divergent, linear subsegments, of which the anterior is the longer; the cilia of both subsegments are of the extremest pale-yellow at the tip; moreover, the first subsegment is black-fringed at the extremity of its fore-margin and also on the inner half of its lower-margin ; and all the cilia of the second subsegment are also so coloured; but both these subsegments have black scales at their apices at the base of the pale cilia.

"The first two segments of the hindwing are cleft up to three-fourths of the wing-length; they are faintly browned posteriorly and the lower margin of the second segment has the palest yellowish cilia. The third segment is so extraordinarily short that it only reaches a little beyond the cleft between the first two segments; it is very slender, and has in the middle of the dorsal margin a small deep-black scale-tuft, and at its apex is edged with a large rounded black scale-spot enclosing both margins.

"Underside coloured almost like the upperside.

"Habitat. — Java. I have named the species after its discoverer, Herr J. af Tengström, the author of the 'Bidrag till Finlands Fjäril-Fauna.'"

In the following year Zeller published figures of this species, but without any text beyond description, in Bull. Soc. Nat. Moscou. Figure 17 shows the whole insect, but it is to be noted that the second segment is here shown as cleft from about 1/4, whereas figure 20 (which gives a more enlarged view of two wings) shows this cleft from 1/2 only in accordance with the description. Figures 18 and 19 show the mid- and hind-leg.

The following is a redescription of one of Zeller's original specimens of D. tengstroemi, now preserved in Lord Walsingham's collection. It is labelled "Java, Tengstr." and also " Type 2/2 " :—

♀. Expanse 12 mm. Palpi long, slender, semi-erect, pale-ferruginous; second joint very slightly dilated at apex, where it is banded with dark-ferruginous; third joint slightly over half length of second, acuminate, broadly banded with dark-ferruginous at base and apex. Antennae dark-ferruginous, dotted with whitish above. Head light-ferruginous, top of crown with long anteriorly-erected scales. Thorax light-ferruginous; pectus marked with whitish. Abdomen stout, light-ferruginous with traces of whitish submedian spots on second segment, and of a narrow transverse white band along posterior edge of third segment; ventral surface white, mottled on sides with ferruginous-golden, fourth segment margined posteriorly with ferruginous-golden. Foreleg whitish-ferruginous, tibia with apical scale-tuft of darker ferruginous scales (but no "white spines"). Midleg whitish-ferruginous, tibia with apical scale-tuft of darker-ferruginous scales (spurs broken). [Hindlegs missing.]

Forewing cleft from rather within 3/5, first segment moderately broad with slight hinder-angle, second segment expanded posteriorly and again cleft to one-half of its own length, subsegments linear, first parallel to first segment, divergent from second: bright ferruginous-golden slightly suffused with light ferruginous: first segment lightly suffused with ferruginous except on costa at 1/4 length of segment, cut at about 2/3 by a nearly obsolete inwardly-oblique whitish line ; second segment lightly suffused with ferruginous, first subsegment with a minute whitish dot near base. Cilia on costa light-ferruginous, slightly darker on base of first segment, on first segment black at 2/5 as a slight bar, with slight blackish admixture at 3/5 and 4/5; at apex black; on hinder-margin of first segment whitish-ochreous from 2/3 to immediately before hinder-angle blackish-ferruginous, a hinder-angle a small blackish wisp preceded by a very narrow ferruginous wisp, on termen pale-ferruginous with a blackish basal line; on fore-margin of second segment whitish-ochreous, beyond 3/4 blackish-ferruginous, at apex of first subsegment wliitish-ocbreous with a broad blackish basal line surrounding apex of subsegment and forming a very small posteriorly-directed scale-tooth; on hinder-margin of first subsegment dark-ferruginous to 1/2, beyond 1/2 whitish-ochreous; on fore-margin of second subsegment dark-ferruginous to 1/2, beyond 1/2 blackish; at apex of second subsegment whitish-ochreous with a black basal line produced into a small posteriorly-directed tornal scale-tooth; on dorsum whitish-ochreous, a small blackish wisp beneath base of second cleft, cilia beyond this darker. [N.B. — The cilia on the forewing are in very good order, and there is no sign of there ever having been a scale-tooth beneath the base of the first cleft.]

Hindwing cleft from about 3/5 and from near base, segments linear; bright ferruginous-golden slightly suffused with light-ferruginous. Cilia whitish-ochreous; third segment with a large apical blackish-ferruginous scale-tooth on both margins, a few small scattered black scales on fore-margin, and a small blackish tooth on dorsum sliglitly before 1/2.

Habitat. — Zeller's original specimens, one of which I have examined, were from Java. The only other examples which I have seen are two from Queensland in Lord Walsingham's collection, one from Cedar Bay (Meek, 1894), the other — very worn and possibly not really tengstroemi, its condition making its identification doubtful — from Geraldton, near Cairns (Meek, 1894).
