Malipatil Institute of Plant Sciences, Department of Agriculture and Rural Affairs, Swan Street, Burnley, Victoria 3121, Australia Abstract Malipatil, M.B., 1991. Three new species of Gminatellus Miller from northern Australia (Heteroptera: Reduviidae). Memoirs of the Museum of Victoria 52: 355-359. Three new species of Gminatellus Miller are described: 6'. elegans sp. nov. (Northern Territory and Queensland including the Torres Strait Islands), G.fasciatus sp. nov. (Queens- land) and G. maeulutus sp. nov. (Queensland). A key to the species of Gminatellus is given.

Ground colour orange with red tinge, with following fuscous: eyes, most of antenna, apices of labium, tarsi and tibia, hind femur, distal half-two-thirds of fore- and mid- femora, apices of pronotal spines, distal live- sixths of hemelytra, wings and most of distal five-sixths of abdominal dorsum. Body and legs subshiny, densely covered with short, golden yellow setal hairs. Body 11.20 (11.20-12.60); maximum width 3.50 (2.60-3.78). Head. Length 2.50 (2.38-2.58), width across eyes 1.12 (1.18-1.25), interocular space 0.63 (0.60-0.68), interocellar space 0.42 (0.38-0.45). eye-ocellar space 0.28 (0.22-0.23): eve length 0.57 (0.52-0.54), eye width 0.30. Length of antennal segments: 1, 4.12 (3.98-4.48); II. 1.33 (1.26-1.33); III, 1.47 (1.40-1.47); IV, strongly curved. Labium extending to anterior quarter of prosternum, length of segments: I, 1.33 (1.19- 133); II, 1.26 (1.12-1. 15); III, 0.42 (0.35-0.36), labrum short, one-eighth as long as first labial segment. Thorax. Pronotum with dorsal spines long and acutely produced (fFig. I), length 2.52 (2.24-2.52), width anterior margin 1.26 ( 1.1 2- 1.26), maximum width 2.74 (2.55-2.94). Scutel- lum with apex acutely pointed and upcurved, length 0.84 (0.88-0.98), width 1.12(1.32-1.40). Legs with tarsi 3 segmented, distal segment subequal to proximal 2 segments together. Hemelytra exceeding abdomen by one-quarter their length, length 7.28 (6.72-8.26), length corium 5. 1 8 (4.48-5.46), width membrane 2.38 (2.20-2.80). Abdomen. Lateral margins gradually widened to posterior margin of fourth visible segment and gradually narrowed to posterior end; con- ncxiva at posterior margins of third and fourth visible segments produced to point, those of lat- ter segment more prominent (e.g., fig. 8). Three minute dorsal scent gland scars distinct between visible terga II— III, III-IV and IV-V. Genitalia. Male: Pygophore posterior margin produced medially (fig. 10). Paramere (fig. 11) slender, slightly curved in middle. Aedeagus with flap on dorsal surface .sclerotised (fig. 12), ventral surface with 2 opposable median rows of long spines and 2 batches of lateral sclerotised spinules exterior to spines in pattern (fig. 13). and distal end of endosoma with numerous fine setal spines. Female: First valvula (VII) and first valvifer (Vfl ) (fig. 14), styloid apically modified to a tube like structure, tergite 9 (t9) (fig. 14), tergite 10 (tlO) narrow, flap-like, folded under. Remarks. Gminatellus elegans can be easily- distinguished from the type species, G. debilis. by the presence of fuscous areas on the femur and the dorsum of abdomen, and the more acutely produced apex of scutellum. There is considerable variation in coloration in the type series. In some paratvpes (e.g., Iron Range, 5-10 and 1 1-1 7 May 1968) most of the mid-femur is fuscous. The Northern Territory specimen is small (8.96) and narrow (2.10) and has fore- and mid-femora with narrow annular fuscous band at about midlength and about dis- tal quarter uniformly fuscous (fig. 3).

Fascia (Latin) band or stripe, alludes to the fuscous bands on visible abdomi- nal tergites IV and V. Remarks. Gminatellus fasciatus may be readily distinguished from G. elegans by its conspicuous broad fuscous lateral bands on visible abdomi- nal tergites IV and V (fig. 8). The West Normanby River specimens exhibit considerable colour variations, particularly in having the distal half of the femora uniformly fuscous (fig. 5) and the postocular part of the head dorsally also lightly fuscous.

Hcmelytra well exceeding abdomen, length 6.30, corium with conspicuous circular white wax covered area (fig. 7), length 4.40, width membrane 2.10. Abdomen. Lateral margins conspicuously explanately produced (fig. 9). Genitalia. Male unavailable. Female as in G. elegans. Etymology. Macula ( Latin) spot or mark, alludes to the white circular spot on the corium. Remarks. Gminatellus maculatus can be readily distinguished from all other species of the genus by the white circular wax covered spot on the corium, and the conspicuously explanate mar- gins on the visible abdominal terga IV and V.
