Steirodon (Peucestes) dentatum woronovi Gorochov, 2025

Steirodon (Peucestes) dentatum woronovi Gorochov subsp. nov.

( Figs 14, 15 View Figs 1–15 , 22, 23 View Figs 16–23 , 28, 29 View Figs 24–37 )

Etymology. This subspecies is named after its collector, Russian and Soviet botanist Yu.N. Woronov.

Type material. Holotype – male, COLOMBIA: “ Rio Magdalena / Columbia, A.S. / Woronov ”, 27 April – 9 May 1926 ( ZIN) . Paratype – male with same data as for holotype ( ZIN) .

Description. Male (holotype). General appearance is very similar to that of nominotypical subspecies but with following characteristic features: body distinctly smaller and uniformly greenish; rostral tubercles of head intermediate between those of S. (P.) para sp. nov. and male of S. (P.) d. dentatum and almost as in female of latter subspecies ( Fig. 11 View Figs 1–15 ); pronotum practically indistinguished from that of this female (compare Figs 12, 13 and 14, 15 View Figs 1–15 ); tegmina with distal parts distinctly less narrow than in female of nominotypical subspecies (as in Fig. 22 View Figs 16–23 ), with stridulatory apparatus as in Figs 23 View Figs 16–23 , 28, 29 View Figs 24–37 (stridulatory vein of left tegmen about 5 mm in length and with nearby 83 ventral teeth: most medial of large and dark teeth located distinctly more near medial edge of tegmen than in S. para sp. nov.); abdominal apex almost as in S. (P.) para sp. nov., but styli of genital plate shorter (distance between bases of styli about 1.5 times as great as stylus length, but in S. para sp. n., this distance approximately equal to stylus length).

Variations. Coloration and structure of body practically indistinguishable from those of holotype ( Figs 22, 23 View Figs 16–23 , 28, 29 View Figs 24–37 ), but genital plate with very short and obtuse-angled posteromedian projection, and styli or this plate almost 1.2 times as long as in holotype of this subspecies and distinctly shorter than in male of S. (P.) para sp. nov.

Female unknown.

Length (mm). Body 38–40; body with wings 81– 83; pronotum 12–12.5; tegmina 67–68; hind femora 32.8–33.5.

Comparison. The new species is very similar to the nominotypical subspecies but with the following differences: the rostral tubercles of head are less clearly divided into four denticles; the tegmina are somewhat shorter; their distal portions are wid- er (compare Figs 21 and 22 View Figs 16–23 ), but this difference for males is somewhat less distinct than in these figures. From S. (P.) para sp. nov., the new subspecies differs in the same characters of the head and pronotum as S. (P.) d. dentatum as well as the large stridulatory teeth of the male left tegmen located very near its medial edge (for comparison see Figs 20 and 23 View Figs 16–23 ), and from all other Peucestes representatives, in the same pronotal and colorational characters as S. (P.) para sp. nov.
