Aspidiotus bornmuelleri Lindinger, 1911, rev. comb. (Hemiptera: Coccomorpha: Diaspididae), a neglected endemic species from Macaronesia, with comments on the genus Cryptophyllaspis, and further notes on the scale insect fauna of Canary Islands, Spain

Cryptophyllaspis bornmuelleri (Lindinger) (Hemiptera: Diaspididae), an endemic plant-galling species from the Canary Islands, has been recollected in Tenerife. The galls induced by this species on Globularia salicina leaves and the diaspidid adult female are redescribed and illustrated. Detailed study of the species has resulted in the combination Aspidiotus bornmuelleri Lindinger being revived, with C. bornmuelleri sunk as a junior synonym. Its taxonomic history, and comments on the genus Cryptophyllaspis and the other species pertaining to it, are reported. Further data on the scale insect fauna of Canary Islands are also presented

Fertility sparing treatment for bilateral borderline ovarian tumor. A case report and management strategy explication

A bilateral adnexal mass with suspected carcinosis could be a challenging experience for the gynecologist especially in fertile age and in patients with a desire for pregnancy. A 26-year-old patient who came to the outpatient clinical observation for bilateral, multilocular pelvic masses, with more than 4 papillary structures, color score 2, hypomobile compared to the uterus and rectum, respectively of 65 and 68mm in maximum diameter, free liquid in the abdomen and suspected for ovarian neoplasm. Positive tumor markers and a strong desire of a Fertility Sparing Treatment (FST). A 2-steps surgical approach managed to perform a diagnosis of bilateral ovarian borderline tumor with implants and a fertility sparing surgery. Harvesting and cryopreserving oocytes prior to the cytoreductive intervention was successfully performed

Cryptophyllaspis Cockerell 1897

The genus <i>Cryptophyllaspis</i> Cockerell, 1897 and its species <p> In 1897, Cockerell erected <i>Cryptophyllaspis</i> as a subgenus of <i>Aspidiotus</i>, with <i>A. occultus</i> Green, 1896 as the type species. Cockerell (1897) gave the following explanation for the erection of the new subgenus: “ <i>A form discovered by Green in Ceylon, living in leaf-gall of</i> Grewia ”. In 1899, Cockerell himself changed the status of <i>Cryptophyllaspis</i> from subgeneric to generic rank without any explanation. Fernald (1903) accepted the generic status of <i>Cryptophyllaspis</i> and considered it to be close to <i>Aspidiotus</i>.</p> <p> Subsequently, a few other gall-forming diaspidids were included in the genus <i>Cryptophyllaspis</i>, namely <i>C. ruebsaameni</i> Cockerell, 1902; <i>C. liquidambaris</i> Kotinsky, 1903; <i>C. elongata</i> (Green, 1905), and <i>C. bornmuelleri,</i> the last two having been described previously in the genus <i>Aspidiotus.</i> Of these, <i>C. liquidambaris</i> is a North American species, <i>C. occulta, C. elongata</i> and <i>C. ruebsaameni</i> are Oriental (from Sri Lanka and Papua New Guinea respectively), while <i>C. bornmuelleri</i> is a Macaronesian species.</p> <p> The inclusion of these species in <i>Cryptophyllaspis</i> was controversial. Lindinger (1911) did not recognise the genus <i>Cryptophyllaspis</i> [as suggested by Rübsaamen (1902)] for the new species <i>bornmuelleri</i> and described it in the genus <i>Aspidiotus</i>. Ferris (1938, 1941) observed that the ability to be a gall-maker could hardly be taken as a basis for distinguishing a genus and that the validity of genus <i>Cryptophyllaspis</i> could be determined only by a study of the species then included in it. As a consequence, <i>C. liquidambaris</i> was transferred to the genus <i>Diaspidiotus</i> (Ferris 1938a) and <i>C. occulta</i> and <i>C. elongata</i> were placed in <i>Aspidiotus</i> (Ferris 1941). Borchsenius (1966) simply accepted the genus <i>Cryptophyllaspis</i> and included four species: <i>C. occulta</i>, <i>C. elongata</i>, <i>C. ruebsaameni</i> and <i>C. bornmuelleri.</i> This situation did not change until the work of Williams and Watson (1988) and Normark <i>et al.</i> (2014). The history and present systematic position of the four <i>Cryptophyllaspis</i> species are discussed below.</p>Published as part of <i>Pellizzari, Giuseppina & Porcelli, Francesco, 2017, Aspidiotus bornmuelleri Lindinger, 1911, rev. comb.

Alien scale insects (Hemiptera Coccoidea) in European and Mediterranean countries: the fate of new and old introductions. Phytoparasitica 42 (5): 713-721

This contribution focuses on recent interceptions and introductions of alien scale insects and their current distribution in European and Mediterranean countries. Data and collections were gathered in markets, nurseries, and botanical gardens, mostly in Italy, either indoors or outdoors. New or recent records of the following alien species are presented: Exallomochlus hispidus (Morrison); Ferrisia virgata (Cockerell) (Pseudococcidae); Coccus viridis (Green); Milviscutulus mangiferae (Green) (Coccidae); Aonidiella orientalis (Newstead); Aspidiotus destructor Signoret; Aulacaspis tubercularis Newstead; Fiorinia fioriniae Targioni Tozzet ti ; Lepidosaphes pinnaeformis (Bouché); Pseudaulacaspis brimblecombei Williams (Diaspididae). New data and pest status of Phoenicococcus marlatti Cockerell (Phoenicococcidae) and Trabutina mannipara (Hemprich & Ehrenberg) (Pseudococcidae) are also re- ported. The possible repeated introductions of the latter from North Africa to south Italy by trans-Mediterranean winds, is hypothesized

Cryptophyllaspis occulta

<i>Cryptophyllaspis occulta</i> (Green, 1896) <p> This minuscule species forms minute rounded galls on the upper leaf surfaces of <i>Grewia orientalis</i> L. (Malvaceae). It is known only from the original record in Sri Lanka. According to Green (1896), the scales settle on the leaf underside, and the adult female becomes completely enclosed in the leaf tissue. Green placed this species in <i>Aspidiotus</i>, but Cockerell (1897) referred to it as <i>Aspidiotus (Cryptophyllaspis) occultus.</i> Leonardi (1897) transferred it to <i>Hemiberlesia</i> and Cockerell (1899) placed it in <i>Cryptophyllaspis</i>. Ferris (1938) presented a drawing of <i>C. occulta</i> based on specimens from the type material; three years later, the same author in his in-depth study on the genus <i>Aspidiotus</i> considered it to be an <i>Aspidiotus</i> species (Ferris, 1941).
