No full textThalamoporella kharinadiensis Guha & Gopikrishna, 2004 (Fig. 11, Table 8) Thalamoporella kharinadiensis Guha & Gopikrishna, 2004: 23, figs 20, 21. Material examined. GIS/B 0231–0270. Yellowish limestone west of Haripar, Kharinadi Formation, lower Miocene (Aquitanian), 23°22’08’’ N, 68° 49’40’’ E, elevation 20 m, 14 January 2011, DST project, New Delhi. Description. Colony erect, bilaminar. Autozooids arranged quincuncially in alternating longitudinal series, rectangular, bordered by indistinct, raised, smooth autozooidal borders. Orifices subcircular, a little wider than long, strongly arched distally with a concave proximal margin (Fig. 11A, B). Cryptocyst shallow, smooth, gently sloping towards opesiular region. Adoral area narrow lacking tubercles. Opesiules large, rounded, unequal, deeply sunken, adjacent to lateral walls proximal to orifice. Avicularia at bifurcation of rows, c. 75% of autozooidal length, vicarious, elongate, straight, with rounded rostrum directed distally; foramen somewhat elongate-pyriform in eroded present material, c. 80% of avicularian length, cryptocyst little preserved proximally, smooth (Fig. 11B). Ovicells not observed. Remarks. The present material agrees with T. kharinadiensis Guha & Gopikrishna, 2004, but the preservation is poor, reflected in the details of the avicularium and apparent absence of pores in the cryptocyst. Additionally, most of the autozooids in a colony show anomalous growth, i.e. incomplete cryptocysts, that might reflect growth in a low pH setting.Published as part of Sonar, Mohan A., Pawar, Ravi V. & Wayal, Dyaneshwar V., 2022, Fossil Thalamoporellidae (Bryozoa) from Paleogene-Neogene sediments of western Kachchh, Gujarat, India, pp. 251-274 in Zootaxa 5104 (2) on page 264, DOI: 10.11646/zootaxa.5104.2.5, http://zenodo.org/record/628083

No full textThalamoporella dorothea Guha & Gopikrishna, 2004 (Fig. 9, Table 6) Thalamoporella dorothea Guha & Gopikrishna, 2004: 10, figs 4, 5. Material examined. GIS/B 0196–0203. Gypseous shale Harudi, Harudi Formation, middle Eocene (Lutetian), 23 ° 31’25” N, 68 ° 41’07” E, elevation 10 m, 13 January 2011, DST project, New Delhi. GIS/B 0204–0210. Waior Limestone, Maniyara Fort Formation, upper Oligocene (Chattian), 23 ° 25’30” N, 68°41’58” E, elevation 6 m, 13 January 2011, DST project, New Delhi. Description. Colony erect, quadriserial, stem four-sided, dichotomously branching. Autozooids in alternating longitudinal series, more or less elongate-rectangular, cryptocystal margins raised, coarsely granular, slightly tapering proximally. Orifice transversely D-shaped, arched distal margin thick, raised, the proximal rim elevated, weakly concave (Fig. 9A, B). Adoral areas narrow, with indistinct tubercles. Two large opesiules, equal, longitudinally oval, adjacent to lateral walls of zooid below proximal orificial rim, polypide tube slightly sunken. Cryptocyst long, narrow, with minute perforations, deeply sunken proximally (Fig. 9A). Avicularia and ovicells not observed. Remarks. The present material conforms to Thalamoporella dorothea Guha & Gopikrishna, 2004 in all essential characters. The species superficially resembles Thalamoporella tewarii Guha & Gopikrishna, 2004 (p. 27, figs 24, 25). Both species have an erect growth form and lack avicularia, but the latter has more zooidal series, and stems expand distally while autozooids are not so narrow and elongate as in T. dorothea. In its erect habit, the present species may be compared with Thalamoporella victoriensis Soule, Soule & Chaney, 1992, but this species is bilaminar, with broader stems.Published as part of Sonar, Mohan A., Pawar, Ravi V. & Wayal, Dyaneshwar V., 2022, Fossil Thalamoporellidae (Bryozoa) from Paleogene-Neogene sediments of western Kachchh, Gujarat, India, pp. 251-274 in Zootaxa 5104 (2) on pages 260-261, DOI: 10.11646/zootaxa.5104.2.5, http://zenodo.org/record/628083

Thalamoporella minuta Guha & Gopikrishnan 2004
No full textThalamoporella minuta Guha & Gopikrishnan, 2004 (Fig. 12, Table 9) Thalamoporella minuta Guha & Gopikrishna, 2004: 12 , figs 6, 7. Material examined. GIS/B 0271–0299: yellowish siltstone of Waghot cliff section and claystone of Kankawati River south of Vinjhan village, Chhasra Formation, late Lower Miocene (Burdigalian), 23°03’10’’ N, 69°00’23’’ E, elevation 25 m, 15 January 2011, DST project, New Delhi. Description. Colony encrusting, unilaminar. Autozooids rectangular with parallel or slightly convex lateral margins, bordered by distinct, thin, slightly raised, sutured boundaries. Orifice circular to subcircular and wider than long, the arched distal margin raised, proximal margin concave (Fig. 12A). Adoral areas narrow without tubercles. Two subrounded, unequal opesiules close to lateral walls. Cryptocyst perforated, shallow, granular, slightly depressed in opesiular region. Avicularia small, oval, located at either right-hand or left-hand distolateral corner of orifice at bifurcation of rows, with rounded rostrum directed distolaterally (Fig. 12B). Ovicells not observed. Remarks. The present material overall agrees with T. minuta Guha & Gopikrishna, 2004 except that opesiules are unequal-sized, autozooidal boundaries in some autozooids are slightly raised and avicularian crossbars are broken, thus not exhibiting the distinctive θ (theta) or figure-eight shape.Published as part of Sonar, Mohan A., Pawar, Ravi V. & Wayal, Dyaneshwar V., 2022, Fossil Thalamoporellidae (Bryozoa) from Paleogene-Neogene sediments of western Kachchh, Gujarat, India, pp. 251-274 in Zootaxa 5104 (2) on page 264, DOI: 10.11646/zootaxa.5104.2.5, http://zenodo.org/record/628083
Thalamoporella kachchhensis Guha & Gopikrishna 2004
No full textThalamoporella kachchhensis Guha & Gopikrishna, 2004 (Fig. 10, Table 7) Thalamoporella kachchhensis Guha & Gopikrishna, 2004: 20, figs 16‒19. Material examined. GIS/B 0211–0230. Yellow limestone, Murachbann, 2 km from Walaram Teerthdham, Chhasra Formation, late lower Miocene (Burdigalian), 23 ° 30’10” N, 68 ° 52’99” E, elevation 91–93 m, 13 January 2011, DST project, New Delhi. Description. Colony erect, bilaminar. Autozooids elongate, narrow, generally parallel-sided (Fig. 10A), surrounded by a thick, distinct, mural rim (Fig. 10B). Orifices large, elongate-oval to transversely D-shaped, distal border highly arched, raised, proximal margin concave. Adoral areas narrow, without tubercles. Conspicuous paired oval opesiules present near lateral walls of autozooids proximal to orifice, mostly of equal size, flanking a deeply sunken polypide tube (Fig. 10C). Cryptocyst shallow, perforated more densely in proximal half or twothirds. Avicularia at bifurcation of rows, drop–shaped, c. 75–80% of autozooidal length (Fig. 10B, D), with slightly raised acute symmetrical rostrum, foramen elongate-oval, more than half of avicularium length, cryptocyst granular. Ovicells not observed. Remarks. The present species superficially resembles Thalamoporella vinjhaniensis Guha & Gopikrishna, 2004 in the shape of avicularium. However, in that species the avicularium is torqued toward the sibling zooid. Thalamoporella kachchhensis also closely resembles T. floridana (Osburn, 1914) in the shape of avicularia (see Chaney et al. 1989), however, in T. floridana avicularia are c. 65% of zooidal length, adoral tubercles are well developed and irregular, and opesiules are unequal. The present species also closely resembles T. gothica (Busk, 1856) in the shape of the avicularium (see Chaney et al. 1989, p. 344, fig. d; Soule et al. 1999, p. 19, figs 25–28). However, T. gothica has comparatively short and wide autozooids, orifices wider than high and small or no adoral tubercles. Thalamoporella gracilata Tilbrook, Hayward & Gordon, 2001 shows some resemblance in the shape of the avicularium, but it differs from the present species in orifice shape and opesiule size.Published as part of Sonar, Mohan A., Pawar, Ravi V. & Wayal, Dyaneshwar V., 2022, Fossil Thalamoporellidae (Bryozoa) from Paleogene-Neogene sediments of western Kachchh, Gujarat, India, pp. 251-274 in Zootaxa 5104 (2) on page 262, DOI: 10.11646/zootaxa.5104.2.5, http://zenodo.org/record/628083

Paratypes: 2 males labelled ‘ Polypedilum (P.) ascium Chaudhuri, Guha & Das Gupta, Bhutan, Thimpu (27.47, 89.46), 23.x.1978, Coll. B.C. Nandi; 1 male labelled ‘ India, West Bengal, Bolpur (23.67, 87.61), 18.viii.1977, Coll. A. Chatterjee’; 1 male labelled ‘ India, West Bengal, Burdwan, Burdwan Town (23.23, 87.86), 03.iii.1979, Coll. S.K. Nandi’; 2 males labelled India, West Bengal, Alipurduar, Pukuria (26.49, 89.53), 11.vi.1984, Coll. T. Dutta; 1 male labelled ‘ India, Bankura, Susunia Hills (23.67, 87.02), Coll. T. Mukherjee, 26.v.2018. Remarks. The species can be recognised by its characteristic axe shaped inferior volsella (Figure 5A). Upon examination of the paratype specimens we found that the species have an outer lateral seta (Figure 5B) at 0.5–0.62 from the apex which was overlooked by Chaudhuri et al. (1981). Ecology. The species having a wide temperature tolerance (eurythermic) is recorded from Thimpu, Bhutan (27.47. 89.46), a part of Himalaya Biodiversity hotspot, where summer temperature is 21°C and Sususnia Hills of Bankura during the course of this study where mercury reaches beyond 40°C during the summer.Published as part of Mukherjee, Tuhar, Mukherjee, Bindarika & Hazra, Niladri, 2020, Revision of the Oriental species of Polypedilum Kieffer (Diptera: Chironomidae) with their phylogenetic relationship, pp. 31-69 in Zootaxa 4820 (1) on page 41, DOI: 10.11646/zootaxa.4820.1.3, http://zenodo.org/record/439725

No full textThalamoporella vinjhanensis Guha & Gopikrishna, 2004 (Fig. 15, Table 12) Thalamoporella vinjhanensis Guha & Gopikrishna, 2004: 39, figs 37, 38. Material examined. GIS/B 0353–0361. Yellowish limestone at cliff section of Lakdi Nadi near Tera village, Chhasra Formation, lower Miocene (Burdigalian), 23°22’19’’ N, 68°58’10’’ E, elevation 52–56 m, 15 January 2011, DST project, New Delhi. Description. Colony erect, bilaminar. Autozooids rectangular, parallel-sided or lateral margins weakly convex, bordered by thick, smooth, distinct boundaries (Fig. 15A). Orifice subrounded, the arcuate distal rim raised more than the concave proximal margin. Adoral areas narrow with no tubercles. Two opesiules adjacent to lateral walls proximal to orifice, large, rounded, mostly unequal and deeply sunken. Cryptocyst gently sloping in opesiular region, smooth, coarsely perforated (Fig. 15B, C). Avicularia at bifurcation of rows, variably penknife-shaped, longer than autozooids, with subacute rostrum; foramen elongate-oval, about half of avicularian length, pivots often present, cryptocyst fairly well developed proximally, sunken below autozooidal rim, smooth. Avicularium and sibling autozooid torqued toward each other (Fig. 15C). Ovicells not observed. Remarks. The present material shows intracolony variation of the avicularian rostral tips, which are sometimes subacute and others rounded, but it otherwise accords with T. vinjhanensis. The species has some similarity to Thalamoporella longirostrata Maplestone, 1900 (see Soule et al. 1992, p. 53, figs 73, 74; and SEM photo, MOV P10126 from Muddy Creek, Victoria on bryozoa.net), but avicularia of T. longirostrata lack pointed pivots and are not torqued.Published as part of Sonar, Mohan A., Pawar, Ravi V. & Wayal, Dyaneshwar V., 2022, Fossil Thalamoporellidae (Bryozoa) from Paleogene-Neogene sediments of western Kachchh, Gujarat, India, pp. 251-274 in Zootaxa 5104 (2) on pages 268-269, DOI: 10.11646/zootaxa.5104.2.5, http://zenodo.org/record/628083
