Gelastopsis procyon Constant, 2026, sp. nov.

Gelastopsis procyon sp. nov. urn:lsid:zoobank.org:act: 2856ACAD-87A6-4AF2-A95D-5A94F9C33B34 Figs 7–13 Diagnosis The species can be recognized by the following combination of characters: (1) black band of upper portion of frons split in two parts by complete median pale yellowish narrow stripe, sometimes yellowish stripe incomplete and the two black parts remain narrowly joined ventrally (Figs 9B, 12C–D); (2) hind wings narrow (LW/BW = 2.5) with a distinctly reduced anal lobe and vein A2 reaching to about ⅔ of lobe length (Fig. 9F); (3) anal tube in dorsal view moderately elongate, suboval (broadly spatulate) (Fig. 10B); (4) gonostyli in lateral view without distinct anterodorsal process (Fig. 10A). Etymology The species epithet refers to the interrupted black band of the upper half of the frons of the new species, reminicent of the black facial mask of the racoon and allies in the genus Procyon Storr, 1780 (Mammalia, Carnivora, Procyonidae). It is used as a noun in apposition. Type material Holotype AUSTRALIA • ♂; Queensland, 26 km W of ‘Fairview’; 15°35′ S, 144°04′ E; 20 Apr. 1989; G. and A. Daniels leg.; ex UQIC donated 2011; QM.

LT: ♂ (n = 2): 6.0 mm (5.5–6.4); ♀ (n = 1): 6.6 mm; BV/LV = 3.74; BF/LF = 2.23; LP+LM/BT = 0.6; LTg/BTg = 2.91; LW/BW = 2.49. HEAD (Figs 8A–D, 9A–C). Vertex weakly concave, variegated blackish and brown with incomplete pale median stripe, paler along lateral margins; often covered in golden-brown pruinose secretion; margins carinate; anterior and posterior margins moderately curved, subparallel. Dorsal half of frons black with oblique sublateral pale yellowish line with small blackish spots; complete median pale yellowish narrow stripe dividing black area; lower margin of black area bisinuate; two strong, coalescent, wrinkled impressions (carinate dorsally) bearing each central white waxy spot; narrow pale yellowish, transverse band under black zone; ventral half of frons brown with irregular, darker markings, often covered in whitish-yellow pruinose secretion and bearing three transverse, irregular, darker carinae. Sides of head yellowish, turning brown in narrow upper portion. Clypeus dark brown, narrowly yellowish along frontoclypeal suture and with sides blackish; antennae blackish; scape short; pedicel subcylindrical, barrel-shaped. THORAX (Figs 8A–D, 9A–C). Pronotum brown with some irregular, darker markings, often covered in golden-brown pruinose secretion; group of obsolete, slightly paler tubercles at each side; anterior margin broadly curved and posterior margin bisinuate. Mesonotum brown with narrow pale median carina extending to base of scutellum; distinct blackish markings along posterolateral margins stopped at base of scutellum; often covered in golden-brown pruinose secretion; distinct sublateral (peridiscal) carinae. Tegulae brown. TEGMINA (Figs 8A–D, 9E). Costal and sutural margins more or less subparallel; costal margin very weakly sinuate; often covered in golden-brown pruinose secretion (more so in anterior portion); dark brown with irregular, whitish marking along costal margin in distal half; ante-apical, white, transverse stripe; apex sligthly obliquely, roundly truncate. VENATION. ScP+R forking close to base after rather short common stem, ScP+RA and RP running more or less parallel to costal margin; first fork of MP very basal, at the level of ScP+RA–RP separation; first fork of CuA slightly before apex of clavus; clavus closed; Pcu and A1 fused at about ¾ of clavus length; Pcu+A1 reaching apical angle of clavus; numerous cells along posterior half of costal margin; numerous cross-veins on apical third delimiting small, elongate cells. POSTERIOR WINGS (Fig. 9F). Narrow, about 2.5 × longer than broad, with narrow, weakly distinct (no indentation on margin) anal lobe, and vein A2 reaching to about ⅔ of lobe length. All main veins visible from base, forked about nodal line, except MP forked before halflength, and forming few closed cells; transverse veinlets delimiting elongate cells in distal ⅓. LEGS (Figs 8A–D, 9D). Pro- and mesofemora and tibiae dark brown, more or less densely variegated with yellowish-brown (often along median line); pro- and mesotarsi slightly darker apically; posterior legs yellowish-brown with apex of tibial and tarsal spines darker. Pro- and mesofemora and tibiae dorsoventrally flattened, elongate and slender, tibiae distinctly more slender than corresponding femora; metatibiae with 3 lateral and 9 apical spines; first metatarsomere ventrally with darker pad of microsetae at internoapical angle and 9 spines more or less arranged in two rows. Metatibiotarsal formula: (3) 9/9/0. ABDOMEN. Bright red with genital segments brown. MALE TERMINALIA (Figs 10–11). Pygofer (Fig. 10: Py) in lateral view strongly sinuate, moderately broad ventrally and tapering towards upper portion; in dorsal view, posterior margin excavate; in ventral view, posterior margin nearly straight. Anal tube (Fig. 10A–C, E–F: An) in dorsal view moderately elongate, suboval (broadly spatulate), about 1.5 × as long in midline as broad, with rounded apical margin; in lateral view, distinctly downcurved in basal portion, then more or less straight; row of minute teeth along apical margin; anal opening in basal ⅓. Gonostyli (Fig. 10: G) fused on most of length, without distinct anterodorsal process; in lateral view elongate with posterior margin distinctly produced posteriad in middle; in ventral view moderately elongate with apex angularly rounded; in caudal view, gonostyli taken together forming a wide ‘U’, with lateral portion upcurved. Aedeagus (Fig. 11) mostly membranous with lateral, incurved, sclerotized process on each side, slightly downcurved in distal portion and apically blunt, articulated to lateroventral process of periandrium; lateroventral process of periandrium with basal apodeme directed cephalad, corpus strongly but shortly projecting ventrad, then distinctly upcurved in lateral view and moderately curved mesad in dorsal view, apex pointed. Distribution and biology The species is currently recorded from two areas: around Laura in the Cape York Peninsula (Cape York bioregion) and in Normanton in the Gulf of Carpentaria area of Queensland (Gulf Plains bioregion) (Fig. 7). The specimens were collected in March to May. They are cryptic when sitting on the branches of their host plant, Acacia sp. (Figs 12–13) in open Eucalyptus woodland.
