Australian Calopompilus species

These notes were to assist with identification of this wasp: https://www.inaturalist.org/observations/23364814

According to the ALA/AFD, Australia has eleven named species in the genus Calopompilus (Hymenoptera: Pompilidae). Here are links and copied text for the primary descriptions, with some key characteristics of relevance to iNaturalist highlighted. (A "line" is one 12th of an inch - I have inserted measurements in millimeters.)

Calopompilus affectata (Smith, 1868)

Female. Length 10 lines [21 mm]. Black, with the two basal segments of the abdomen ferruginous, wings maculated. Head as wide as the thorax, the face and cheeks with a fine griseous pile, the head thinly sprinkled with fuscous hairs ; the antennae bright ferruginous ; the labrum, mandibles, and palpi, dark ferruginous. Thorax : the posterior margin of the prothorax arched ; the sides parallel ; the metathorax, the coxse, and sides, covered with a fine glossy pile, reflecting golden tints in different lights ; the truncation of the metathorax smooth, not shining, the upper surface transversely grooved ; wings fulvo-hyaline, their apical margins with a narrow fuscous border, and also a quadrate fuscous spot at the apex of the third discoidal cell, extending upwards into the corners of the second and third sub-marginals ; legs bright ferruginous, with black coxae. Abdomen : the extreme base, also the base of the second segment in the middle, its apical margin broadly, and the following segments entirely black; the apical segment with bright ferruginous hairs. Hab. South Australia (Moreton Bay ?) . In the British Museum.

Calopompilus aurifrons (Smith, 1855)

Female. Length 12 lines [25 mm]. — Black: the face covered with fine short golden pubescence ; the antennae, clypeus, palpi and mandibles reddish-yellow, the tips of the femora, tibiae, tarsi and wings of the same colour ; the first recurrent nervure entering the second submarginal cell at one-third from its apex ; the apical margins of the wings have a narrow fuscous border ; the thorax clothed above with short black velvety pubescence ; metathorax short, truncate, and transversely rugose-striate, the striation strongest at the sides ; the posterior tibiae strongly serrated exteriorly, the anterior pairs spinose. Abdomen : the first segment and basal half of the second black, with very short black pubescence, the apical half of the second and the whole of the following segments clothed with short golden pubescence ; beneath smooth and shining, the margins of the segments rufo-piceous. Hab. Australia.

Calopompilus auropilosellus (Turner, 1915)

Long. Female 13 mm. ; Male 11 mm. Female . Clypeus broad and short, broadly subtruncate at the apex ; labrum slightly exposed, subtruncate at the apex. Antennae rather short and stout; second joint of the flagellum about as long as the first and third combined, third a little longer than the fourth. Eyes almost parallel on the inner margin ; ocelli in a small triangle, the posterior pair twice as far from the eyes as from each other. Scutellum broadly subtruncate at the apex ; median segment with a deep median sulcus. Abdomen subopaque, the second ventral segment with a distinct transverse groove near the base; pygidium broad. The whole insect more or less densely clothed with golden pubescence, most closely on the posterior margin of the pronotum, the pleurae, the median segment, and the apical angles of the dorsal segments. Hind tibiae spinose, distinctly serrate on the outer side. Second abscissa of the radius about equal to the third ; first recurrent nervure received at two-fifths from the base of the second cubital cell, second at three-fifths from the base of the third cubital cell. Cubitus of the hind wing interstitial with the transverse median nervure. The black bands on the fore wing are broad and completely cross the wing, the first on the basal nervure, the second from the base of the radial cell, the third is apical ; the two latter converge towards the lower margin. Hab. Mt. Wellington, Tasmania, 2200 ft. ; January to March. The male differs in having the flagellum wholly black, the margins of the abdominal segments pale ferruginous ; the second joint of the flagellum a little shorter than the third. The colour of the wings is similar to that of C. molestus Sm., but the antennae are shorter and stouter, the hind tibiae more distinctly serrate, the position of the recurrent nervures very different, also the colour of the pubescence. The antennae are not quite so stout and short as in pictipennis Sm.

Calopompilus defensor (Smith, 1868)

Female. Length 7-10 lines [15-21 mm]. Black, with ferruginous wings. Head narrower than the thorax, antennae incrassate ; the body pilose, in some lights having a dull violet lustre. Thorax : truncate posteriorly, slightly rounded anteriorly ; the posterior margin of the prothorax curved ; the sides parallel ; the wings ferruginous, their bases and apical margins narrowly dark fuscous ; the nervures ferruginous, black at the extreme base of the anterior wings ; the metathorax impunctate, and with an impressed line above, in the middle. Hab. South Australia. In the British Museum.

Calopompilus irritabilis (Smith, 1868)

Female. Length 4.75 - 6 lines [10-13 mm]. Black: the wings with a yellow fascia ; the body covered with a fine silvery silky pile, very bright and glittering in certain lights, and most dense on the face, and body beneath. Thorax : the posterior margin of the prothorax rounded ; wings fusco-hyaline, with a broad yellow fascia towards the apex of the anterior wings, enclosing the marginal, two sub-marginal, and apical half of the third discoidal cell ; the fascia does not quite extend to the posterior margin of the wing : the spines at the apex of the tibiae pale testaceous ; the extreme apex of the anterior tibiae and joints of the tarsi, as well as the apex of the intermediate tibiae, ferruginous. Abdomen rounded at the base. The male closely resembles the female, but has the anterior tibiae and tarsi, as well as the antennae, ferruginous ; the posterior tibiae with a pale spot at their base. Hab. Australia. In the British Museum.

Calopompilus molestus (Smith, 1862)

Female. — Black, and thinly covered with a silky cinereous pile ; the antennae ferruginous, with three or four of the apical joints black ; the mandibles rufo-piceous at their apex ; the vertex, and the pro- and mesothorax with rufo-fuscous reflection ; the posterior margin of the prothorax curved; the tibiae and tarsi dull, ferruginous and sparingly set with short acute spines ; the wings fuscous, with two broad yellow fasciae on the superior pair, their base sub-hyaline ; the posterior wings sub-hyaline, with a fuscous border at their apical margins. Abdomen slightly shining, covered with cinereous silky pile, which is most dense at the base of each segment. Length 9 lines [19 mm]. Hab. Australia (near Sydney). Tn my own Collection.

Calopompilus nugenti (Turner, 1910)

Female . Differs from the typical form [of Sphex (Isodontia) abditus] in the following details : — the second joint of the flagellum is distinctly longer than the third, the punctures on the thorax are very shallow, the pubescence on the thorax and median segment is black, erect, and sparse, and the apical joint of the tarsi is ferruginous, leaving only the coxae and trochanters black on the legs. Length 19 mm. Hab. Cairns, Q. Kohl gives the locality Sikkim, but expresses doubt as to the correctness of the formation. In my opinion abditus is scarcely distinct from aurifrons Sm. from Aru, the latter species differing in the testaceous margins of the abdominal segments which are also slightly pruinose. In Queensland the present form seems to be very scarce and has not been previously recorded.
