Patellapis (Chaetalictus) terminalis ( Smith 1853)

Halictus terminalis Smith, 1853: 54 .

( Figs. 126a–g )

Diagnosis. The female is similar to that of P. minima in having a reticulate scutum and broad, translucent margins of metasomal terga T1–T4. They can be distinguish by the supraclypeal area and paraocular area, which is extensively reticulate in P. minima and at only partly reticulate in P. terminalis . The male is unknown.

Description

Female. Bl = 5,3–5,7mm. General habitus ( Fig. 126e ). Head. L = 1,5–1,6mm; W = 1,7–1,8mm. Head wider than long ( Fig. 126a ). Integument black except mandibles and malar area usually partly reddish-brown. Face shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus, supraclypeal area and paraocular area sparsely punctate; surface polished; surface of supraclypeal area finely reticulate; surface of paraocular area finely sculptured. Clypeoantennal distance 0,3mm. Antennae reddish-brown. Mesosoma. L = 1,1–1,2mm; W (ITS) = 1,3–1,4mm. Integument black. Scutum shiny; surface extensively and finely reticulate; disc moderately densely punctate (i = 1,5d) ( Fig. 126b ). Scutellum as illustrated in Fig. 126c . Scutum, scutellum, metanotum, mesepisternum and propodeum with greyish to pallid brownish, erect hairs. Basal area of propodeum as illustrated in Fig. 126c ; propodeum slightly dull; completely reticulate and sparsely punctate. Marginal region of posterior truncation slightly dull; extensively reticulate. Wings. Hyaline. Legs. Integument brownish. Vestiture greyish. Ts finely serrate; with about 8–10 short, oblique projections ( Fig. 126f ). Bp as illustrated ( Fig. 126g ). Metasoma. L = 2,8–3,3mm; W = 1,9–2,0mm. Integument brownish to blackish-brown; margins of T pallid brown to pale and broadly translucent. No apical hair bands. Prepygidial fimbria pallid brownish. Metasomal terga T1–T2 as illustrated in Fig. 126d .
