Overview
Reprinted from: Snelling, R. 1970. STUDIES ON NORTH AMERICAN BEES OF THE GENUS HYLAEUS. 5. THE SUBGENERA HYLAEUS. S. STR. AND PARAPROSOPIS (HYMENOPTERA: COLLETIDAE) Contributions in Science, No. 180.

This species extends transcontinentally from southern Canada to northern Mexico. Over most of this range H. cressoni is a common species. The populations from eastern, northern and montane regions commonly have the clypeus and pronotal collars immaculate. Some individuals within these populations may also lack maculae on the pronotal lobes and the tegulae. Clinal variation occurs uniformly from east to west, from north to south and with decreasing elevation. This elinal variation is manifested in two concordant characters, an increase in the tone and extent of the pale maculae and a decrease in the size and density of metasomal punctation, so that populations at opposite poles of the eline are very different in appearance. Specimens from Turlock, California, for example have the face marks bright yellowish, the apical portion of the c1ypeus is strongly infused with reddish color and the pronotal lobes and collar and the tegulae are conspicuously maculate. The abdomen is smooth and shiny, with few or no distinct punctures. Such specimens contrast sharply with others from the New England area in which the maculae are dull yellowish-white, the c1ypeus is black and the thorax completely immaculate; such specimens may have the metasomal tergites with obvious fine scattered punctures. The same is true if one compares the Turlock specimens with samples from Revelstoke, British Columbia, or with others from Sonora Pass in the Sierra Nevada of California. In all cases the two extremes are connected, through the intervening portions of the range, by a series of specimens of intermediate character. These series of intermediates form, in their entirety, a well-defined cline for the characters noted.

Under these cricumstances continued recognition of H. pasadenae, described from Pasadena, California, as a subspecies of H. cresson;, a status accorded this form in the past, is untenable. This bee does not possess any of the characteristics of a definable subspecies and I agree with Metz in placing H. pasadenae in the synonymy of H. cressoni. The subsequent continued recognition of H. pasadenae as a subspecies of H. cressoni seems to be traceable to Cockerell's refusal to accept the synonymy published by Metz. However persistent such a refusal has been, there appears to be no published indication why Metz's proposal should not be adopted.

Lovell's H. teleporus was proposed for H. cressoni-like males in which the lateral face marks terminate acutely at the level of the lower margin of the antennal sockets. These males seem to occur sporadically within the populations of H. cressoll; in northern and montane areas. I have examined the terminalia of males of this form and find no distinctive characters which will serve to separate H. teleporus from H. cresson;. I believe that H. teleporus should be placed in the synonymy of H. cressoni until conclusive evidence for the specificity of this form can be advanced.

Cockerell and Sumner described H. repolitlls from a single female taken at Ogden, Utah. Dr. Rozen sent the type to me and I find nothing in any of its characters to justify separating this bee from H. cressoni. The nearly smooth basal zone of thc propodcum is exactly like that of many females of H. cressoni available to me which also show a strong reduction in the longitudinal rugulae of the basal zone. This characteristic cannot be correlated with other features nor is it geographically consistent.

Dr. Rozen has sent the type of H. laciniallls, and there is no doubt that this name, too, is a synonym of H. cressoni cressoni. Before I had the opportunity to study thc type, I was puzzled by the peculiar shape fa the seventh ventrite as figured by Cockerell and Sumner (1930: 10, fig. 2). With the type slide before me, it is clear that the apical lobes of this ventrite have been broken off. The poor preparation of the slide, on which everything is badly flattened and distorted, is also responsible for the seemingly expanded gonocoxites, as these were illustrated by Cockerell and Sumner.

Cockerell and Sumner cite the type as follows: "COLORADO-Boulder, May 24, 1913 (F. E. Lutz)." The labels on the specimens clearly read "Boulder, Colo., M. D. Ellis, May 24, 1913," and "Salix." Since the specimen and slides are in accord with the original description and figures, and the type is so marked in Cockerell's handwriting, I have no reason to doubt that this is the true type.

DISTRIBUTION�Southeastern Canada and the New England states, west to Minnesota, southward to Georgia; May to October.

FLOWER RECORDS�Being in flight throughout the warmer parts of the year, cressoni visits a wide range of plants, collections having been made on species of the following genera: Anethum, Apocynum, Castanea, Ceanothus, Crataegus, Daucus, Erigeron, Evonymus, Hydrangea, Melilotus, Pyracantha, Rhus, Rubus and Solidago. It has also been collected on the following crop plants: apple, celery, cowpea, dill, mustard and parsnip. Robertson (1929) has recorded it from the following plants: Amorpha, Aruncus, Aster, Blephilia, Boltonia, Cacalia, Cctpsella, Cardamine, Cerastium, Cicuta, Cornus, Crypt at cienia, Eryngium, Eulophus, Eupatorium, Euphorbia, FragarIa, Galeum, Geum, Heracleum, Krigia, Lepidium, Lyco pus, Malva, Osmorrhiza, Oxypohs, Part henium, Pastinaca, Polygonum, Polytaenia, Potentihla, Prunus, Pycnanthemum, Sahix, Sanicula, Sium, Taenidia, Thaspium, Vaherianehha, Veronica, Viburnum and Zizia. The clypeus in females of cressoni is subject to some variation in that it is maculated in some individuals, the central yellow blotch being quite conspicuous in some specimens, barely evident in others.

Hylaeus (Hylaeus) labiatifrons (Cockerell)


The status of this form, described from a single male from Georgia, is enigmatical. It is known only from the unique type, which I have not examined. Metz (1911) considered it a synonym of H. cressoni, but Mitchell (1960) has elevated it to species level and briefly redescribed the type. Unfortunately, Mitchell's description contributes nothing new to permit the recognition of H. labiatifrons. In all features it seems to agree quite closely with males of H. cressoni cressoni, and seems to differ from that species only in the entirely yellow tibiae.

This difference seems to me to be of little value. Another Nearctic Hylaeus, H. illinoisensis (Robertson), is supposedly recognizable on the same basis. In that species, at least, males with entirely yellow tibiae are exceptional. Even those which have the tibiae wholly yellow show, under intense light, a slightly darker basal two-thirds which corresponds to the black basal area of most specimens. I suspect that the same is true in the case of H. labiatifrons, which I regard as a probable synonym of H. cressoni cressoni. The solution must wait until the type, especially ventrites eight and nine, can be examined and compared with those of the related species.
