Halictus rubrotibialis Cockerell, 1946c: 180 . Syn. n. ( Figs. 81a–e ; 82a–d ) Diagnosis. The male is similar to that of P. pearstonensis in having 6 very strong bristles on the posterior margin of S4. They differ in the structure of the lower gonostylus, which is simple in P. platti and bifid in P. pearstonensis . The female is similar to that of P. disposita , but P. platti lacks the oily bluish shine on the scutum. Description Female . Bl = 5,3mm . Head . L = 1,7mm ; W = 1,8mm . Head about as wide as long ( Fig. 81a ). Integument black except mandibles and malar area partly reddish-brown. Face predominantly shiny and with loose, yellowish and pallid brownish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus strongly and densely punctate; surface shiny. Clypeoantennal distance 0,3mm . Supraclypeal area with a few well separated punctures; surface finely reticulate. Paraocular area strongly and moderately densely punctate; surface extensively and strongly reticulate. Antennae brownish-black. Mesosoma . L = 1,2mm ; W (ITS) = 1,3mm . Integument black. Scutum polished; surface finely reticulate; disc sparsely punctate (i = 3,0–5,0d) ( Fig. 81b ). Scutellum as illustrated in Fig. 81c . Scutum, scutellum, metanotum, mesepisternum and propodeum with greyish and brownish, erect hairs. Pronotal lobe reddish to yellowish. Basal area of propodeum as illustrated in Fig. 81c ; propodeum and marginal region of posterior truncation slightly shiny; surface completely reticulate. Wings . Hyaline. Legs . Integument brownish to yellowishbrown. Vestiture greyish to pallid brownish. Ts moderately strongly serrate, with about 7 small, oblique projections ( Fig. 81d ). Bp as illustrated in Fig. 81e . Metasoma . L = 3,0mm; W = 1,9mm . Integument reddishbrown; margins translucent. No apical hair bands on metasomal terga. Prepygidial fimbria mostly yellowish. FIGURE 81.

Integument black except mandibles, malar area, clypeus and paraocular area partly reddish-brown. Clypeus, supraclypeal area, paraocular area and vertex covered with erect, greyish hairs. Mandibles simple. Antennae brownish. Flagellomeres of normal structure (not knotty). A4 as long as A3. Mesosoma . L = 0,9–1,0mm; W (ITS) = 1,0– 1,1mm . Integument black. Scutum polished; sparsely punctate (i = 2,0d); surface partly reticulate anteriorly ( Fig. 82b ). Scutellum as illustrated in Fig. 82c . Scutum, scutellum, metanotum, mesepisternum and propodeum with greyish to dark greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 82c ; propodeum slightly shiny; surface completely reticulate and sparsely punctate. Marginal region of posterior truncation slightly shiny and extensively reticulate. Wings . Hyaline. Legs . Integument reddish. Vestiture greyish. Metasoma . L = 2,7–2,8mm ; W = 1,4–1,5mm . Integument reddish to brownish-black; T1–T2 extensively reddish; T3–T6 extensively brownish to blackish; margins mostly pallid brownish and broadly translucent ( Fig. 82d ). Apical plate broad; rounded apically. Posterior margin of S4 with a sparse row of 6 very strong, long, curled, erect bristles. Metasomal sterna S5-S6 without dense hair patches (e.g. Fig. 79d ).
