Heteroptera (Hemiptera: Prosorrhyncha) New to Canada. Part 2

Journal of the Entomological Society of British Columbia, Dec 2004 by Scudder, G G E

ABSTRACT

The occurrence of an additional six species of true bugs newly recognized in Canada is documented. New US state records are given for two pentatomid species, and a key to the species of Neottiglossa Kirby in Canada is included.

INTRODUCTION

In a previous paper (Scudder 2000), 34 species of true bugs newly recognized in Canada was documented. At that time, it was noted that additional species would be published in Part 2, when all determinations had been confirmed.

In the intervening period, additional species have been included in publications by Schuh (2001), Schwartz and Scudder (2001, 2003) and Paiera et al. (2004).

I now report an additional six species new to Canada.

SPECIES NEW TO CANADA

Family CYDNIDAE

Amnestus basidentatus Froeschner

QC: 2[male] 2[female], Aylmer, lumière, Boisé décidu., 29.v.1989 (L. LeSage) [CNC].

This species has been swept from grass, and occurs from New York south to Florida and Cuba, and west to Missouri and Texas (Froeschner 1960). A key to separate A. basidentatus from the other three species of Amnestus Dallas that occur in Canada (Maw et al. 2000) is provided by McPherson (1982). A. basidentatus has four marginal pegs on each juga, and the male has a characteristic anterior subbasal tooth on the front tibia, giving this segment a notched appearance on its inner surface. The ventral subapical spine on the hind femur of the male is also shorter than the width of the femur, while in the female, the last abdominal sternum lacks a flattened glabrous area.

Family MIRIDAE

Pinophyhis carneolus (Knight)

SK: 1[male] Nipawin, Jack pine, 7.vi.1968 (FIS 605) [CNC].

The genus Pinophylus Schwartz & Schuh was described by Schwartz and Schuh (1999) with three contained species, one of which P. rolfsi (Knight), was reported from Alberta, British Columbia and Yukon, and south to Oregon and Colorado. Pinophyhis carneohis was reported from District of Columbia, Maryland, North Carolina, Pennsylvania, Virginia, West Virginia and Wisconsin, and like P. rolfsi is strongly sexually dimorphic. P. carneolus is distinguished from P. rolfsi by the slightly reddish brown coloration, and the form of the male genitalia in which the vesica is more strongly curved than in P. rolfsi. P. carneolus is reported to breed on Virginia pine, Pinus virginiana Mill, in the United States (Knight 1927; Schwartz and Schuh 1999).

Family PENTATOMIDAE

Neottiglossa sulcifrons Stål

SK: 1[female], Indian Head, Aspen Grove, 3.viii. 1939 (C.R. Douglas) [CNC].

Four species of the genus Neottiglossa Kirby are now known from Canada. Two of these, N. trilineata (Kirby) and N. undata (Say), occur across Canada from Yukon to Newfoundland, while N. tumidifrons Downes is confined to British Columbia in Canada (Maw et al. 2000). The following key modified from that in Rider (1989), will separate the species of Neottiglossa now known from Canada.

1. Coxae pale yellow; evaporative surface on pterothorax ventrally pale yellow to brown-grey with contrasting black punctures ..........................................................2

-Coxae fuscous to black; evaporative surfaces on pterothorax ventrally black with concolorous punctures ......................3

2. Dorsal surface of head and propleura mostly black with concolorous punctures ...................................... strilineata (Kirby)

-Dorsal surface of head and propleura with large areas pale yellow to brown with black puncture.......................snndata (Say)

3. Trochanters dark fuscous; scutellum lacking pale median line ......sulcifrons Stål

-Trochanters pale; scutellum usually with pale median line. tumidifrons Downes

N. sulcifrons is usually collected in grassy habitats (McPherson 1982) and is recorded through much of the eastern and central Untied States, south to Georgia, Texas, New Mexico and Arizona. Froeschner (1988) and Rider (1989) summarize the records for the US states. To these can be added the following new state records.

COLORADO: 1[female], Boulder, Flagstaff Cn., 5800' (1705 m), 8.viii. 1961 (J.R. Stainer); 1[male] 1[female], id, 11.vi.1961; 1[female], Boulder, 12.vi.1961 (B.H. Poole); 2[female], Mt. Evans, 9800' (2987 m), Doolittle Ranch, 10.viii. 1961 (B.H. Poole); 1[male], Nederland, Science Lodge, 9500' (2896 m), 1.vii.1961 (J.R. Stainer); 1[male], id, 6.vii.1961; 1[female], id, 9000' (2743 m), 29.vii.1961; 3[female], Nederland, Caribou, 8700' (2652 m), 7.viii. 1961 (J.R. Stainer). OKLAHOMA: 1[female], Texoma Lk., 15.vii.1954 (J.G. Chillcott). SOUTH CAROLINA: 1[female], Aiken, 24.viii. 1957 (W.R. Richards); 1[female], Montmorenci, 23.vi.1957 (W.R.M. Mason) [CNC].
