Andrena (Micrandrena) chananaea Pisanty & Wood 2025, sp. nov.

3.1.2.8.Andrena(Micrandrena)chananaeaPisanty & Wood sp. nov. Figures 7, 18 F, L, 21 A Etymology. Nominative feminine singular form of the Latin adjective chananaeus (= Canaanite). Diagnosis. Within the Andrena minutula species group, the female of A. chananaea is characterized by the combination of a shagreened, strongly punctate clypeus, often with a strong impunctate midline (Fig. 18 F), densely and strongly punctate scutum (Figs 7 C, 18 L), and shagreened tergal discs with at most obscure punctation (Fig. 7 D). These characters apply equally well to A. minutula (Kirby) itself, and we could not identify any good morphological character that separates females of the two taxa. Within the Levantine Micrandrena fauna, the female of A. chananaea most closely resembles A. sillata Warncke and A. alfkenelloides cardalia Warncke. Compared to A. sillata, A. chananaea has stronger and coarser clypeal puncturing (Fig. 18 E, F), and slightly sparser and coarser scutal punctation (Fig. 18 K, L). Compared to A. a. cardalia, it has a more evenly sculptured clypeus (very densely punctate and transversely striated basally, partly smooth medioapically in A. a. cardalia; Figs 16 A, 18 F) and a dull, microreticulate, and very weakly punctate tergal disc 1 (Fig. 7 D; usually smoother and more distinctly punctate in A. a. cardalia, especially in the second generation). The male of A. chananaea is very hard to diagnose among members of the A. minutula group, due to its extreme morphological variability, both among and within the two seasonal generations. The main consistent characters are a short flagellomere 1, clypeus and scutum which are densely punctured and usually at least partly shagreened, terga which are highly variable but at least weakly punctate, and simple genitalia. The male is closest to A. alfkenella Perkins and A. alfkenelloides cardalia, but exhibits subtle differences in the shape of the genitalia, with the gonostyli only slightly narrowed basally (inner margin of gonostylus more strongly narrowing basally in A. alfkenella and A. a. cardalia), and the penis valves distinctly broader basally vs. apically (more uniformly narrow in the comparison species) (Fig. 21 A – C). In general overview, the genitalia of A. chananaea appear somewhat more robust and enlarged. In addition, males of A. chananaea usually possess a longer flagellomere 1 when compared to A. a. cardalia, and tergal discs that are more strongly shagreened and more weakly and finely punctured when compared to both A. alfkenella and A. a. cardalia, but all these traits are far too variable among individuals of these species to constitute reliable differentiating characters. The male of A. chananaea may also resemble A. minutuloides, but its scutal punctation is denser, and its penis valves are narrower basally (Fig. 21 A, F). Description. First generation female. Body length: 5.5–6 mm. — Integumental colour: Body and legs black. Flagellum black, partly covered by greyish scales especially on distal flagellomeres. Tarsi black to brown.

Few inconspicuous short dark hairs occur on ocellar triangle and behind upper margin of compound eyes. Hair of facial fovea brownish on upper ⅓ of fovea, more whitish below (Fig. 7 B, C). Scutum with brownish hair, centrally short to minute, interspersed with few long erect hairs, underlying cuticle visible, peripherally short to medium and erect. Metanotum and periphery of scutellum with erect, short to long brownish hair (Fig. 7 C). Mesepisternum with long whitish hair (Fig. 7 A). Propodeal corbicula incomplete, posterodorsal fringe composed of long plumose whitish hair, corbicular surface with few long, simple whitish hairs. Leg hair mostly whitish to golden, flocculus incomplete, white, tibial scopal hair simple, whitish, becoming brown near posterobasal margin of tibia (Fig. 7 A). Majority of tergal discs 1–2 essentially hairless, 3–4 with minute inconspicuous bright hair, tergal discs laterally with few sparse short to medium white hairs. Tergal marginal zones 2–4 with prominent, broadly interrupted white hair bands, consisting of very sparse medium-lengthed hairs emerging from the basal rim of the marginal zone, and denser short hairs emerging near its apex. Tergal marginal zone 4 with very weak continuous band of very sparse medium-lengthed whitish hairs emerging from its basal rim. Terminal fringe light brown, flanked by few white hairs (Fig. 7 D). — Head: 1.2 times broader than long. Mandibles bidentate, moderately crossed. Galea finely shagreened (Fig. 7 B). Labral process trapezoidal, not much broader than long. Clypeus domed, entirely shagreened and matt except for an occasionally shinier apical margin, punctation strong, distance between punctures 1–2 puncture diameters, an impunctate midline is usually weakly to strongly developed (Figs 7 B, 18 F). Ventrolateral part of paraocular area very smooth, strongly and densely punctured. Frons and rest of paraocular area strongly longitudinally striated, with coarse punctures embedded between the striations (Fig. 7 B, C). Flagellomere 1 0.9–1 times as long as 2 + 3, 2 slightly shorter than 3 (Fig. 7 B). Facial fovea dorsally moderately narrow, here about 0.4 times as broad as antennocular distance, tapering ventrally, extending from level of lower end of lateral ocellus to slightly above base of clypeus, lower ⅔ separated from compound eye by smooth cuticular strip. Frons with distinct medial carina, dorsally usually ending with a smooth broadened flat area under the medial ocellus. Distance of fovea from lateral ocellus about 2 ocellus diameters (Fig. 7 B, C). Lateral ocelli not connected posteriorly by trough-like furrow. Ocelloccipital distance roughly 1 ocellus diameter. Preoccipital ridge weakly carinate (Fig. 7 C). — Mesosoma: Dorsolateral angle of pronotum not elevated. Scutum usually strongly shagreened and matt, rarely weakly to strongly shiny and partly smooth, punctation strong and dense, distance between punctures <0.5 to 1 puncture diameter. Scutellum similar, anterior part often shiny and somewhat smooth (Figs 7 C, 18 L). Mesepisternum posteriorly finely alveolate, anteriorly gradually strongly and densely, obliquely punctured. Surface of propodeal corbicula reticulated, with few large punctures around hair bases. Posterior part of propodeum strongly differentiated into horizontal vs. vertical parts. Posterolateral area of propodeum rugose-areolate. Propodeal triangle delineated from flanking areas by change in sculpture, not surrounded by carina, horizontal part coarsely radially rugose, vertical part very finely areolated (Fig. 7 C). Hind pretarsal claw with small inner tooth. Recurrent vein 1 meeting submarginal cell 2 more or less at its middle. Nervulus distinctly antefurcal to almost interstitial (Fig. 7 A). — Metasoma: Tergal discs 1–2 strongly shagreened and matt, with hints of fine punctation blended into the shagreening; 3 and especially 4 often more weakly shagreened, 3 with stronger hints of fine, dense punctation. Tergal marginal zones impunctate, weakly depressed, moderately arched, 2–3 centrally occupying 0.4–0.7 of tergal length, 1–2 distinctly shagreened and matt, the following gradually more weakly shagreened (Fig. 7 D). Pygidial plate normally developed. — Second generation female.

Sculpturing of horizontal part of propodeal triangle slightly finer, more rugose-areolate. — Metasoma: As in first generation. — First generation male.
