Colletes kuhlmanni Ferrari , new species

( Figs. 34A–F View FIGURE 34 )

Diagnosis. The combination of pubescence mostly pale-yellow, malar area 1.2x as long as basal depth of mandible, paraocular area with longitudinal band of black hairs, posterior hind tibial spur ciliate, and T1 sparsely and minutely punctate is sufficient to distinguish C. kuhlmanni n. sp. from all other species of the genus found in Chile.

Colletes kuhlmanni n. sp. is most similar to C. gilvus , but these species can be differentiated by T1 sparsely and minutely punctate in C. kuhlmanni n. sp. (T1 moderately densely and finely punctate in C. gilvus ). Additionally, the female of these species differ in the disc of T1, which is covered only with erect long hairs in C. kuhlmanni n. sp. (T1 with erect long and sparse appressed hairs in female C. gilvus ). Also, F1 is approximately as long as its apical width in male C. kuhlmanni n. sp. (F1 ~1.3x as long as its apical width in C. gilvus ).

Description. FEMALE ( Figs. 34A, 34C View FIGURE 34 , 31F View FIGURE 31 ): Dimensions (mm): Approximate body length 11.0; head width 3.5; head length 2.7; intertegular distance 2.8; forewing length 7.3.

Colouration: Black except reddish-brown marked on distal 1/3 of mandible. Dark-brown on tegula, wing veins (except vein R of forewing black), distitarsi (except distal 1/5 pale-brown), distal half of tarsal claws, marginal zones of T1–T5. Pale-brown on proximal half of tarsal claws. Pale-yellow on tibial spurs, marginal zones of S1– S5.

Structure: Labrum medially concave; concavity margined by lateral ridges. Clypeal mid-longitudinal area narrowly (0.4x MOD) and deeply depressed on upper half; depression broad and shallow on lower half; adjacent lateral area convex; apicomedial ridge absent. Malar area ~1.2x basal depth of mandible (34:28). F1 ~1.7x as long as its apical width (40:23). UID:LID (69:60). Genal area concave behind upper summit of compound eyes in lateral view. Dorsolateral angle of pronotum modified into a spine. Horizontal surface of metapostnotum 0.45x as long as metanotum (28:62); metapostnotal pits well-delimited; posterior transverse carina straight and narrowly interrupted medially. Posteromedial surface of front coxa without spine. Posterior hind tibial spur ciliate. Hind basitarsus 3.6x longer than broad (54:15). Outer rami of hind tarsal claws ~ 2x as long as inner rami (30:16). Posterolateral area of S6 flat and lacking carina; marginal zone depressed.

Pubescence: Pale-yellow, plumose, erect, long on lateral slopes of clypeus and supraclypeal area, interantennal area, coxae, trochanters (except very short on dorsal surface), ventral surface of femora, S1; such hairs very long on genal area (progressively shorter towards outer margin of compound eye), mesepisternum, metepisternum, superior margin of lateral surface of propodeum, T1. Mixed pale-yellow and black, plumose, erect, long hairs on paraocular and vertexal areas, mesoscutum, scutellum, metanotum. Pale-yellow, suberect, moderately long setae on mandible, dorsal surface of mid and hind basitarsi and tibiae. Pale-yellow, erect, very long setae on posterior margin of mid and hind basitarsi; thick setae on ventral surface of mid and hind tarsi (thickest towards distal margin). Pale-yellow, suberect, very long hairs, which are branched only apically on anterior surface of hind femur and tibia. T2–T5 with pale-yellow, dense, appressed hairs (T4–T5 also with black, erect, long setae). Posterior 1/3 of S3–S5 covered with setae and plumose hairs intermixed. S2 with pale-yellow, erect, short hairs, which are branched only apically.

Surface sculpture: Clypeus shiny throughout; mid-longitudinal depression densely and finely punctate; adjacent convex area smooth on upper 3/4, lower 1/4 longitudinally striate. Malar area longitudinally striate. Supraclypeal area with very sparse moderately coarse punctures; interspaces smooth and shiny. Paraocular area densely and moderately coarsely punctate below (sparser and coarser towards supraclypeal area); punctures crowded and moderately fine above; interspaces smooth and shiny throughout. Frontal area punctures crowded; interspaces rugose and dull. Vertexal punctation dense with moderately fine punctures intermingled with coarse ones; interspaces smooth and shiny. Mesoscutum coarsely punctate; densely punctate on anterior and lateral areas; sparsely punctate on mid-posterior area. Scutellar disc densely punctate; posterior margin punctures crowded. Mesepisternum coarsely punctate; densely punctate anteriorly to episternal groove; slightly sparser posteriorly to groove. Mesoscutal, scutellar, and mesepisternal interspaces smooth and shiny throughout. Metanotum punctures crowded; interspaces rugulose but somewhat shiny. Metepisternum obliquely striate medially; rugulose above. Lateral surface of propodeum rugulose; punctation difficult to spot. Upper area of vertical surface of metapostnotum smooth medially. Metasomal terga sparsely and minutely punctate; interspaces smooth and shiny throughout. Metasoma sterna finely and shallowly punctate; densest posterolaterally; interspaces imbricate.

Pubescence: Mesoscutum, scutellum and metanotum without black hairs. Metasomal appressed pubescence restricted to marginal zones; discs of T2–T3 covered with plumose, erect, moderately long hairs; discs of T4–T5 with long setae.
