Description
Small black and creamy-white marked (henceforth referred to as pale) bee with a body length of 4 mm in both sexes. Similar in size and colouration to the small species of Flavipanurgus, particularly F. ibericus Warncke and F. fuzetus. Both sexes can be separated from this genus by the length of the proboscis which is over three times longer than the length of a mandible (Figure 1), compared to around the length of a mandible in Flavipanurgus (Figure 2). The glossa is longer than the prementum and the first segment of the labial palpus is subequal to the length of the second to the fourth segments taken together, placing C. baldocki in subgenus Camptopoeum sensu strictu. The male is characterised by the facial markings (Figure 1), with pale maculation restricted to the ventral surface of the antennal scape, the clypeus and the basal half of the mandibles. The female is characterised by the almost completely black face and reduced pale markings on the metasomal terga.
Description. FEMALE: Body length 4 mm.
Head: Head slightly wider than, ground colour black. The eyes are blue-grey in life though this disappears after death. Proboscis long, three to four times the length of a mandible. Glossa proportionally long, approximately three times the length of the prementum. The length of the first segment of the labial palpus is subequal to the length of the second to the fourth segments taken together. Head entirely black except for a narrow white line along the upper clypeal margin, where this abuts the supraclypeal area. At its greatest extent this spans the entire width and is broader in the centre. At its least extent it is reduced to a single, pale central dot. Mandibles dull orangeyellow in the basal half, apically dark reddish-brown. Antennal scape entirely black.
Antennal segments 3-13 ventrally marked with dull orange-yellow, dorsally dark to brown.
Mesosoma: Mesonotum densely and weakly punctate, distance between the punctures approximately equal to a puncture width. Puncture interspaces weakly shining with faintmicroreticulation. The mesosoma is entirely black apart from pale markings as follows: the rear half of the pronotal lobes, two very fine lines on the rear margin of the scutellum (absent in one out of four specimens) and a broad band occupying much of the dorsal surface of the metanotum. The tegulae are transparent brown with some obscure pale markings on the wing bases. Legs black-brown apart from the following pale markings: a small dorsal apical spot on femora 1-2 and a broad streak almost the entire length of the front of tibia 1-2. The tarsi and tibia 3 are a slightly paler, translucent brown. Pilosity silvery. The tibial scopa of sparse, pale, curved hairs: the ventral ones roughly twice as long as the dorsal. Stigma and veins of forewing brown.
Metasoma: Terga densely but weakly punctured, the punctures barely visible against the background reticulation. The distance between the punctures one to two times a puncture width. Tergal margins 1-4 impressed, colour varying from black (concolourous with ground colour of terga) to reddish brown. Terga with pairs of lateral pale spots immediately anterior to the depressed marginal area. On tergum 1 there is a single pair. On terga 2-4 there are two on both sides, each pair formed by an irregular, subtriangular spot at the rear corner and a short dash between this and the centre line of the tergite. The exterior spots on T4 are frequently missing and the dashes may be absent progressively from T2 to T4, such that the darkest specimens only have the exterior spots on T1-3. Sternites entirely dark. The pygidium is subtriangular, roughly as wide at the base as long, with slightly convex sides and a rounded tip. There is a very faint hint of a longitudinal, central raised area.
MALE: Body length 4 mm. Head:
Head slightly wider than long, ground colour black. Proboscis long, three to four times the length of a mandible. Glossa proportionally long, approximately three times the length of the prementum. The length of the first segment of the labial palpus is subequal to the length of the second to the fourth segments taken together. Clypeus pale except for a pair of small black dots, each located towards the midpoint of the lateral clypeal margin (Figure 1). Some males may additionally have two or three small, linear pale dots at the lower edge of the supraclypeal area and a small, irregular dot in the lower half of the paraocular area. Mandibles yellow in the basal third to half, apically reddish brown. Antennal scape ventrally pale marked, dorsally black. Antennal
segments 3-13 ventrally marked with orange, dorsally dark to brown.
Mesosoma: Mesonotum densely and weakly punctate, distance between the punctures approximately equal to a puncture width. Puncture interspaces weakly shining with faint microreticulation. Pronotum, pronotal lobes, scutellum and metanotum pale marked. Tegulae and wing bases brown with variable faint pale markings. Proximal margin of scutellum black with a central black marking extending posteriorly, separating the two pale patches on the distal scutellar margin (seen in Figure 6). Legs black-brown apart from the following pale markings: the apical third of femora 1-3, the entirety of tibia 1-2, tarsi 1 and basitarsi 2 in the basal half. Pilosity silvery. Stigma and veins of forewing brown.
Metasoma: Terga consistently but weakly punctured, distance between the punctures one to two times a puncture width. Tergal margins 1-5 impressed, colour varying from black (concolourous with ground colour of terga) to reddish brown. Terga 1-5(6) with a pale band immediately anterior to the depressed marginal area, this band generally reaching the lateral margin on terga 1-3. Sternites dark, without pale markings. Genitalia illustrated in Figure 3, showing close similarity to the genitalia of other described Camptopoeum species (e.g. Ruz 1986; Rozen 1986).
