description: Argogorytes pulawskii Girish Kumar & Dubey sp. nov.
(Figs 1–12)
Type material. Holotype ♀, India: Andaman Islands, North Andaman Island, Diglipur, Shyamnagar (13° 14’ 49’’ N & 92° 58’ 25’’ E, altitude 9 m), 12.viii.2019, Coll. A.K. Dubey, ZSIK Regd. No. ZSI/ WGRC /IR/INV.15451.
Diagnosis. Argogorytes pulawskii sp. nov. differs from all other Argogorytes by the following combination of characters: basal four metasomal terga black with pair of small creamy white spots on Gt 1 subapically, and a pair of narrow elongated creamy white bands on Gt 2 subapically (Fig. 10); metanotum black (Fig. 5); wings hyaline except stigma, marginal cell, parts of costal cell and space outside of costal cell III of forewing infumated (Figs 8 & 9); scutellum medially without narrow, transverse, raised smooth area (Fig. 5); posterior margin of Gt 2 –Gt 3 doubleedged (Fig. 7); pygidium narrow, moderately short, subparallel-sided, with median ridge and lateral grove bearing few setigerous punctures (Figs 1 & 10).
Description. Holotype female. Body length 12 mm; forewing length 8 mm.
Colour. Black, following parts creamy white: two narrow elongated marks on base of clypeus, pronotal collar narrowly, pronotal lobe, pair of small spot on T1 subapically and a pair of very narrow elongated band on T2 subapically. Mandible at middle reddish brown; maxillary and labial palpi and ventral sides of all tarsi pale brown; flagellum ventrally and tegula brownish black. Wing membrane clear hyaline except forewing infumate on marginal cell and its periphery and on costal cell; stigma black; veins dark brown.
Vestiture. Short and silvery, some longer setae present on mandible and clypeus, vestiture on labrum pale brownish; pygidial setae short, erect and silvery.
Head. Head height 0.87 × its maximum width in frontal view (Fig 2); interocular distance at base of clypeus 0.92 × that at anterior ocellus; clypeus 2.05 × as wide as high, apical margin in middle shallowly incurved, surface with scattered large punctures interspersed among small punctures (Fig. 3); lower half of front with small punctures, one diameter or less apart on average, and with inconspicuous median carina; upper half of front with somewhat larger punctures, many of them half diameter apart; POL 1.27 × OOL; vertex punctation similar to that on upper front; gena with rather dense small punctures. Antenna as in Figure 4, length of antennal segments as follows: scape: pedicel: fu 1: fu 2: fu 3: fu 4: fu 5: fu 6: fu 7: fu 8: fu 9: fu 10 = 18: 5: 14.5: 13: 12: 11.5: 10: 9.5: 9.5: 9.5: 9.5: 14.8.
Mesosoma. Pronotal collar with anterior, transverse, low, erect carina; mesoscutum anterolaterally with contiguous small punctures, elsewhere with large contiguous pits or punctures; scutellum raised, convex, in middle without narrow, transverse, raised smooth area, posteriorly with small circular pubescent pit, elsewhere with contiguous punctures slightly smaller than those on scutum; metanotum similarly punctate, raised in the middle; mesopleuron adjacent to pronotal lobe somewhat coarsely, closely pitted, remainder with conspicuous, close, oblique to transverse ridges with fine, interspersed small and large setiferous punctures; metapleuron smooth with moderately dense, fine, setiferous punctures; propodeal enclosure triangular, with coarse, slightly irregular longitudinal rugae, margined laterally by short oblique rugae, rest of dorsum with longer oblique rugae basally and shorter rugae apically (Fig. 7); posterior propodeal surface with rugulae radiating outward and upward from metasomal insertion; lateral propodeal surface mostly smooth but with somewhat inconspicuous curved posterolateral rugae; plantulae present on tarsal segments I–IV.
Metasoma. Gt 1 – Gt 3 with small punctures mostly 0.5–1.0 × diameter apart, Gt 4 with smaller, evenly spaced punctures, Gt 5 with fine, moderately dense punctures; posterior margin of Gt 2 – Gt 3 double-edged (Figs 1 & 10); pygidium (Fig. 12) narrow, moderately short, sub-parallel sided, with median ridge and lateral grove bearing few setigerous punctures; Gs 1 with conspicuous complete median keel which is curved in basal half and almost triangular in apical half; Gs 2 raised in to median rounded prominence about a third from base.
Etymology. The species is named after Dr Wojciech J. Pulawski, California Academy of Sciences, USA for honouring his tremendous contribution to taxonomy of Crabronidae.
Distribution. India: Andaman Islands.
