Centris (Melacentris) furcata ( Fabricius, 1804)  nom. rev.

( Figures 3, 4View FIGURES 1 – 4, 7, 8View FIGURES 5 – 8, 10, 12View FIGURES 9 – 12, 14, 16View FIGURES 13 – 16, 25View FIGURE 25)

Bombus furcatus Fabricius, 1804: 350  .

Diagnosis. Female: Fore elaiospathe with anterior secondary comb formed by five giant, apically curved hairs. Primary pygidial plate relatively rhomboid, with posterior margin of secondary plate not projected backwards ( Fig. 10View FIGURES 9 – 12). Male: Clypeus finely areolate with relatively fine and dense punctures laterally, with longitudinal impunctate area on disc. Mediotarsus of hind leg without tuft of plumose hairs ventrally; distitarsus with yellow, dense, plumose hairs forming a comb. Base of hind claw with tuft of branched pubescence, with some simple hairs intermixed ( Fig. 16View FIGURES 13 – 16). Mandible strongly curved apically with three teeth (2nd>1st≈3rd): apical tooth with acute apex, second straight and third rounded ( Figs. 4View FIGURES 1 – 4, 14View FIGURES 13 – 16). This species is most similar to C. atriventris  . Females differ by the width of the mandibular teeth (1st>2nd>4th>3rd in C. furcata  , Fig. 3View FIGURES 1 – 4; 1st>3rd>4th>2nd in C. atriventris  , Fig. 1View FIGURES 1 – 4), by the coloration of the clypeus (dark brown in C. furcata  , Fig. 3View FIGURES 1 – 4; orange brown in C. atriventris  , Fig. 1View FIGURES 1 – 4) and by the shape of the secondary basitibial plate (not projected backwards in C. furcata  , Fig. 10View FIGURES 9 – 12; projected backwards in C. atriventris  , Fig. 9View FIGURES 9 – 12). Males differ mainly by the size of the second and third mandibular teeth (2nd>3rd in C. furcata  , Fig. 14View FIGURES 13 – 16; 3rd>2nd in C. atriventris  , Fig. 13View FIGURES 13 – 16) and by the absence of a tuft of branched hairs at the base of the hind pretarsal claws ( Fig. 16View FIGURES 13 – 16), which is present in C. atriventris  ( Fig. 15View FIGURES 13 – 16).

Mesoscutum and mesoscutellum with intense orange hairs with dark orange tips ( Figs. 3View FIGURES 1 – 4, 7View FIGURES 5 – 8). Legs with light brown pilosity, mainly on fore legs ( Fig. 7View FIGURES 5 – 8). Labrum with brown branched pubescence, interspersed with simple, downwardly directed hairs ( Fig. 3View FIGURES 1 – 4). Terga, except T1, with dense pubescence.

Mandible strongly curved apically with four teeth (1st>2nd≈4th>3rd) of acute apex, except fourth truncated ( Fig. 3View FIGURES 1 – 4). Acetabular carina reaching base of fourth tooth ( Fig. 3View FIGURES 1 – 4). Trimal angle well-developed, acute. Maxillary palpus with four palpomeres (2nd>3rd>1st>4th).
