Paramarginatus Dubey, gen. nov.
No full textParamarginatus Dubey gen. nov. (Figure 19)– Figure 20 (g)) Type species Paramarginatus sarawakensis Dubey sp. nov., by monotypy and present designation. Gender: masculine. Diagnosis Elliptical. Margin crenulate. Thoracic and caudal tracheal pore opening areas not modified in the margin. Median-submedian area with wax gland patches. Longitudinal moulting suture reaching anterior margin. Transverse moulting suture reaching submedian area. Metathorax smaller than mesothorax in median length. Pro-mesothoracic suture not defined. Abdominal segment sutures reaching subdorsal area. Median length of abdominal segment suture VII not reduced medially. Thoracic tracheal furrows absent. Caudal tracheal furrow not so prominent. Vasiform orifice triangular; operculum little more than half length of the orifice; lingula exposed, a pair of long setae subapically. Cephalic and the first abdominal setae absent, eighth abdominal and caudal setae present. Etymology The genus is named ‘ Paramarginatus ’ to indicate its similarity to Aleuromarginatus. Remarks The new genus differs from Aleuromarginatus in the reduced median length of the metathorax, abdominal segment sutures reaching the outer subdorsal area, transverse moulting suture not reaching the margin, the distribution of dorsal setae, having anterior marginal setae and median-submedian wax gland patches, lacking cephalic and first abdominal setae, and having paired submedian lateral longitudinal furrows and wax glands at base of marginal teeth. Puparia of this species are not congeneric with those of the genus Aleuromarginatus; in particular they lack the typical distribution of dorsal hook-shaped setae and submarginal papillae. Puparia of this new genus are similar to those of Chitonaleyrodes Martin, 1999 in the absence of cephalic and first abdominal setae, abdominal segments not reduced in middle length and intersegmental sutures reaching the subdorsum on the abdomen, but differ in the presence of a caudal furrow, triangular vasiform orifice, exposed lingula and wax gland patches on abdominal segments I–VII. Puparia of this new genus also differ from the genus Zaphanera Corbett, 1926 in not having black puparia and anteriorly curved transverse moulting suture,in having a triangular vasiform orifice, and in having lingula not elevated posteriorly and exposed. Two Australian Zaphanera species (Z. rhachisreticulata Martin, 1999; Z. wariensis Martin, 1999) having black puparia, a curved transverse moulting suture and the posteriorly elevated vasiform orifice bearing wax glands on abdominal segments are not assignable to Paramarginatus gen. nov. The new genus differs from the genus Aleuroglandulus Martin, 1999 in having the cephalothorax smaller than abdomen, crenulated margin, in extension of abdominal segment sutures, submedian area of abdominal segment I–VIII with glands, abdominal segment VII not reduced medially and the first abdominal setae absent.Published as part of Dubey, Anil Kumar & Brown, Paul A., 2022, Six new species of Aleuromarginatus Corbett, 1935 and Paramarginatus sarawakensis Dubey gen. and sp. nov.

Elotespora mumbaiensis Rashmi Dubey 2021, sp. nov.
No full textElotespora mumbaiensis Rashmi Dubey sp. nov. (Fig.1) MycoBank MB 840079 Mycelium mostly immersed. Conidiomata eustromatic, cyathiform, scattered, almost superficial somewhat immersed on the substratum, dark brown to black, layers of cell forming textura angularis, unilocular, 22–30 μm diam., 11–14 μm deep. Conidiophores not observed, Conidiogenous cells not observed. Conidogenesis not observed, but Conidiomatal ‘cup’ like structure is visible both under the compound microscope and Scanning Electron Microscope, Conidial secession is not observed, but some part of the conidiomatal ‘cup’ is still attached on the base of seceded conidial chain indicating that conidia are produced directly from the conidiomatal ‘cup’. Conidia are produced directly from the conidiomata and forms acropetal chains having 2–5 conidia per chain, and the chains are sometimes branched. Conidia dry, muriform, initially brown, on maturity turn blackish brown at the apical and basal end, elongated to ellipsoidal, sometimes twisted, 42–80 × 15–24 μm (60.27 × 21.23, n=15) widely obtuse/rounded at the apex, truncate at the base, basal conidia straight and wider than other apical conidia, sometimes conidia initials are also visible on the lateral sides of conidia indicating the branching pattern of the conidial chain. Additional Material/cultures examined: Culture was obtained on Potato Dextrose Agar (PDA) medium and malt extract agar medium (MEA) with different light and dark conditions. Vegetative hyphae grew on medium on seven days but did not sporulate, and culture died. Gene sequence ex-holotype: Not known.

Himalayaleyrodes Dubey, gen. nov.
No full textHimalayaleyrodes Dubey gen. nov. Type species: Himalayaleyrodes sarcococcae Dubey sp. nov. Diagnosis. In life, puparium thick; white; raised on lateral margin by wax palisade; with wax secretions, wax filaments forming dome-shaped structure around puparium; infesting lower surface of leaves and soft green stems; infested area with chlorotic spots. Margin crenulate, with a row of simple setae. Anterior and posterior marginal setae present. Cephalic, eighth abdominal and caudal setae present. First abdominal setae absent. Longitudinal moulting suture reaching margin and transverse moulting suture reaching outer submedian/subdorsal area. Submargin not differentiated from the dorsal disc by a furrow or fold. Submedian area with a band of wax secreting glands. Caudal and thoracic tracheal pore opening area slightly modified into a comb. Cephalothoracic and abdominal segment sutures prominent. Median length of abdominal segment VII shorter than VI. Vasiform orifice triangular, not elevated; operculum subrectangular, covering about half the length of orifice; lingula elongate, exposed, not reaching beyond posterior margin of the orifice, with a pair of fine setae subapically. Thoracic and caudal tracheal furrows absent. Geminate pores present. Simple pores may be present in a band on submedian/ subdorsal area. Ventrally, antennae reaching middle of prothoracic legs. Caudal and thoracic tracheal folds with stipples. Paired ventral setae, microsetae and rostral setae present. Adhesive sacs and spiracles visible. Adults white, with mottling on wings. Etymology. The genus is named after the Himalaya, from where the specimens were collected from areas that receive winter snow. Remarks. Puparia of the new genus resemble that of Bemisia Quaintance & Baker in shape and in having crenulate margin and roughly triangular vasiform orifice, but differs from it in that (characters in parenthesis are that of Bemisia): in life, puparium with copious amount of long wax filaments (such long wax filaments absent), puparium raised on its lateral margin (puparium not raised on its lateral margin), and in having a row of marginal setae (marginal setae absent), a band of simple pores on outer subdorsal area (such band of simple pores absent), a band of wax secreting glands on subdorsum (wax glands likely on submarginal area only), medial length of abdominal segment VII half the length of segment VI (median length of abdominal segment VII much reduced, almost immeasurable), protuberances absent from dorsum (variable degree of protuberances present), and by the absence of the first abdominal and submarginal setae (first abdominal and submarginal setae present); adult males and females of the new genus have mottling on wings (mottling absent on wings), aedeagus constricted in middle (not constricted in middle), in adult male and female the upper and lower compound eyes are connected by three and four ommatidia, respectively (upper and lower compound eye are connected by a single ommatidium, Dubey et al., 2009), sensorial cone on segment VII placed ahead of primary sensoria (Figs 37, 42) (sensorial cone placed posterior or equal to the primary sensoria). Puparia of the new genus and species differing in above-mentioned characteristics from the afer complex also differ in the same characteristics from the tabaci complex. Puparia of the new genus also resemble that of Aleurochiton Tullgren (1907) in having a waxy palisade around margin but differ from it in that (characters in parenthesis are that of Aleurochiton): in life, puparia with long wax filaments forming dome-shaped periphery around margin (such long wax filaments absent around margin but dorsum may be plated with wax), first abdominal setae absent (first abdominal setae present), vasiform orifice triangular in shape (vasiform orifice sub-rectangular), abdominal segment I with two pairs of geminate pores (abdominal segment I with one pair of geminate pores), transverse moulting suture not curved anteriorly and reaching outer submedian/subdorsal area (transverse moulting suture usually curved anteriorly and reaching margin), a band of simple minute pore present on submedian/subdorsal area (such band of simple pores absent on submedian/subdorsal area) and a band of wax secreting plates present on submedian/subdorsal area (such a band of wax plates absent), and ventrally, a submarginal fold present (submarginal ventral fold absent). Himalayaleyrodes gen. n. also differs in puparial characteristics from Asterobemisia Trehan (1940) in that: the transverse moulting suture does not turn anteriorly and reach submedian/subdorsal area whereas in the latter genus the transverse moulting suture turns anteriorly and joins the longitudinal moulting suture, this conjuncture forms a heart-shaped window for adult emergence.Published as part of Dubey, Anil Kumar & Singh, Sudhir, 2017, A new whitefly genus and species, Himalayaleyrodes sarcococcae Dubey (Hemiptera: Aleyrodidae) infesting Christmas box (Buxaceae) in Western Himalaya, India, pp. 531-544 in Zootaxa 4269 (4) on pages 532-533, DOI: 10.11646/zootaxa.4269.4.7, http://zenodo.org/record/58276
Australeurodes Dubey, gen. n.
No full textAustraleurodes Dubey gen. n. Type species: Dialeurolonga operculobata Martin & Carver in Martin, 1999: 69. Holotype puparium. Australia: Queensland, Ipswich, 1.vii. 1952, on Leptospermum saundersoni, in Australian National Insect Collection, Canberra [Not examined]. Diagnosis: Puparium pale, about 1.7 times longer than wide, margin crenulate; margin with a row of setae including anterior and posterior marginal setae, with truly marginal bases (similar to those of anterior and posterior marginal setae); caudal and thoracic tracheal openings at margin shallow indented and with rounded teeth. Dorsal surface smooth, without tubercles; submargin not demarcated from dorsal disc; median length of cephalothorax shorter than abdomen; longitudinal and transverse moulting sutures almost reaching margin; cephalothoracic and abdominal segments suture visible, most reaching outer subdorsal area; median length of abdominal segment VIII apparently reduced, but pockets located on boundary of segment VI/VII. Cephalic and first abdominal setae absent. Eighth abdominal setae present. Vasiform orifice triangular, operculum with 4 pronounced lobes, occupying anterior half to two-thirds of orifice; lingula lobulate and exposed. Thoracic tracheal furrows absent. Caudal furrow narrow, without tubercles. Ventrally tracheal fold stippled. Etymology. The new genus is named after Australia from where the type species was collected and the suffix - aleurodes often used for coining new names in whiteflies. Remarks: The new genus differs from Dialeurolonga by the presence of a row of marginal setae, shallowly indented tracheal combs, median length of abdominal segment VIII much reduced, intersegmental sutures reaching subdorsum, and by the absence of cephalic and first abdominal setae, punctured dorsum and median pore on abdominal segment VIII. It is also unique among whitefly genera in having lobulate operculum occupying only anterior half to two-thirds of the orifice. Australeurodes gen. n. is similar to Bemisia Quaintance & Baker and Parabemisia Takahashi but differs from these genera in the shape of operculum and lingula and by the absence of cephalic setae. In addition, it differs from Bemisia by the presence of marginal setae, and from Parabemisia by the indication of thoracic tracheal combs. This monobasic genus is based on the description of Dialeurolonga operculobata in Martin (1999).
