03D75339FFA2F531FF1D36FCFDFCF83B.taxon	diagnosis	Diagnosis. Alfieriella senguptai sp. n. is much larger than the remaining members of the genus and can be further differentiated from A. laticollis by having the combined width of the elytra wider than the pronotum; and from A. naxiana, A. senguptai has rounded pronotal sides and an apiculate antennal club; and from the similar-looking A. denticulata and A. rabinovitchi, A. senguptai has rounded posterior angles of pronotum and an incised apex of posterior section of the aedeagus.	en	Chen, Yan-Dong, Leschen, Richard A.

03D75339FFA2F531FF1D36FCFDFCF83B.taxon	etymology	Etymology. The specific epithet is dedicated to the Indian entomologist T. Sen Gupta for his contribution to our knowledge of the diversity of Cryptophagidae.	en	Chen, Yan-Dong, Leschen, Richard A. B., Bai, Ming, Yang, Xing-Ke (2020): A new Himalayan species of Alfieriella (Coleoptera: Cryptophagidae). Zootaxa 4819 (3): 571-581, DOI: 10.11646/zootaxa.4819.3.8
03D75339FFA2F531FF1D36FCFDFCF83B.taxon	discussion	Comments. Sen Gupta & Crowson (1971) referred to an unpublished genus, called ‘ Acryptus’, in its own tribe, contained in Sen Gupta’s unpublished PhD thesis. We borrowed specimens of this taxon from the BMNH (Fig. 4). These specimens have the typical 10 - segmented antenna with a large 1 - segmented club shared by all described members of Alfieriella and confirm the placement of the new species in this genus. Alfieriella senguptai can also be considered as a member of Alfieriella by the absence of a pronotal bead, conspicuous subgenal spines, and articulated parameres (Leschen 1996).	en	Chen, Yan-Dong, Leschen, Richard A.

03D75339FFA6F533FF1D3083FD22FE66.taxon	discussion	Comments. These specimens from Crete were first mentioned by Ratti (1976). They were originally identified as Cyprogenia denticulata by Obenberger and this species identification was followed by Leschen (1996). After dissecting these specimens, the true species identification is doubtful. These specimens are 1.14 – 1.43 mm long and the male genitalia are illustrated in Fig. 6. The elytra together are about 1.41 times longer than wide. The male genitalia and the elytral length-to-width ratio are close to Ratti’s description of Alfieriella rabinovitchi. The material of A. rabinovitchi examined by Ratti is questionable as the specimens were labeled as ‘ Typus- Alfieriella decemarticulata m. — Det. W. Wittmer’ (Ratti 1976). Ratti regarded them as A. rabinovitchi because they were collected from the same locality mentioned in Wittmer (1935). The exact identification of these specimens, as well as the types of A. rabinovitchi and A. denticulata, require more study.	en	Chen, Yan-Dong, Leschen, Richard A.
