Patellapis (Patellapis) pseudomontagui sp. n. Timmermann

( Figs. 20a–g ; 21a–h )

Diagnosis. The most similar species is P. montagui . The morphological characters to distinguish the females of both species are very subtile. The females of P. pseudomontagui differ from the females of P. montagui in having the lower part of paraocular area more densely punctate, the scutum more sparsely punctate (i = 2,0d) and the vestiture of hind tibial scopae yellowish (greyish in P. montagui ). The males of P. pseudomontagui differ from P. montagui in the structure and size of the metasomal sternum S8, which is broad in size and deeply emarginated apically in P. pseudomontagui and longish in size and angulated apically in P. montagui .

Description

Female. Bl = 8,5–8,8mm. General habitus ( Fig. 20e ). Head. L = 2,2–2,3mm; W = 2,6–2,7mm. Head wider than long ( Fig. 20a ). Integument black except mandibles partly reddish-brown. Face shiny and with loose, long, brownish, erect hairs except frons and vertex with greyish to yellowish erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus polished; strongly and moderately densely punctate (i = 1,5d). Clypeoantennal distance 0,5mm. Supraclypeal area polished; upper area densely (i = d) and lower area sparsely punctate (i = 2,0–3,0d); surface extensively chagreened. Paraocular area shiny; strongly and densely punctate; surface extensively sculptured. Antennae mostly brownish. Mesosoma. L = 1,6–1,7mm; W (ITS) = 2,1–2,2mm. Integument black. Scutum polished; disc moderately strongly and sparsely punctate (i = 2,0d); partly chagreened anteriorly ( Fig. 20b ). Scutellum as illustrated in Fig. 20c . Scutum and scutellum with brownish, erect hairs. Metanotum, mesepisternum and propodeum with greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 20c ; propodeum shiny, extensively reticulate and with only a few, well separated, minute punctures. Marginal region of posterior truncation completely reticulate. Wings. Fuscous. Legs. Integument blackish-brown. Vestiture yellowish to brownish. Ts coarsely serrate, with about 10 strong, oblique projections ( Fig. 20f ). Bp broad; broadly rounded apically ( Fig. 20g ).

Metasoma. L = 4,8–5,0mm; W = 3,3–3,5mm. Integument blackish-brown; discs and margins of T brownish to pallid brownish; margins partly translucent. T1–T4 with strong, whitish apical hair bands; the bands on T1–T2 mostly present laterally. Prepygidial fimbria brownish. Discs and marginal zones of T1–T3 shiny, conspicuously more dense punctate than the rest of the terga ( Fig. 20d ).

Male. Bl = 7,2–8,3mm. Head. L = 1,7–2,0mm; W = 2,1–2,5mm. Head wider than long ( Fig. 21a ). Integument black except mandibles partly reddish-brown. Clypeus, supraclypeal area, paraocular area, and vertex with loose, greyish, erect hairs; clypeus, supraclypeal area and lower half of paraocular area entirely covered with appressed, white hairs. Mandibles simple. Antennae brownish-black. Flagellomeres knotty. A4 about 2,0 times longer than A3. Mesosoma. L = 1,4–1,7mm; W (ITS) = 1,5–1,7mm. Integument black. Scutum strongly and densely punctate (i = d) ( Fig. 21b ). Scutellum as illustrated in Fig. 21c . Scutum, scutellum, metanotum, mesepisternum and propodeum with long, greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 21c ; propodeum shiny and densely punctate. Marginal region of posterior truncation slightly dull and reticulate. Wings. Slightly fuscous. Legs. Integument brownish to black. Vestiture mostly greyish. Metasoma. L = 4,4–5,4mm; W = 2,4–2,6mm. Integument brownish-black except the margins of T pallid brownish and slightly translucent. Metasomal terga as illustrated in Fig. 21d . Apical plate broad and broadly rounded apically. Posterior margin of S4 with a dense row of coarse, erect bristles. S5 with fanshaped, appressed hair patches laterally ( Fig. 21e ). S7 and S8 as illustrated in Fig. 21f . Genitalia. Genitalia as illustrated in Fig. 21g –h ; gonocoxa shiny and gonostylus simple, without a dorso-lateral projection.
