Lasioglossum medinai ( Vachal, 1895) 

Halictus medinai Vachal, 1895: 148  . Holotype: ♂, Spain, Sevilla, “col. Medina ” ( MCSN), examined. Blüthgen 1923: 239 (syn. of H. villosulus  ). Examined by AP. 

New diagnosis

Morphological examination of the type of Halictus medinai  confirms that this large specimen belongs to the cryptic species. Its size is 7 mm ( Fig. 2View Fig C–D), the punctation of the scutum is denser than in L. villosulum  . Head, punctation of the scutum, sculpture of propodeum and punctation of terga of the male holotype are illustrated ( Fig. 15View Fig).

Morphological examination of the females makes it possible to note immediately, in addition to a larger body size (7 mm), the denser punctation of the scutum ( Fig. 16View Fig) as well as the stronger wrinkles of the propodeum, which reach the posterior edge ( Fig. 17View Fig). In most cases, we can verify the identification using two more subtle characters:

(1) the punctation of the tergum 1 is much more superficial in the middle and on the apical margin, absent in the middle of the apical margin, whereas in L. villosulum  the punctation of the tergum 1 is deeper and the apical margin is punctuated even in the middle ( Fig. 18View Fig).

(2) a small unpunctuated area in front of the larger anterior ocelli, more extended than in L. villosulum  , and punctation around this area finer ( Fig. 19View Fig).

Morphological examination of a single male of L. medinai  obtained by breeding and from Uchaux confirms that males of this species also have denser punctation on the scutum. The genitalia of several large males with denser punctation of the scutum and collected at the same time as females of L. medinai  show only very subtle differences which may be characteristic ( Fig. 20View Fig):

L. medinai  : reflexed gonostylus lobe with apex blunt ( Fig. 20View Fig Cb), outer hind corner more produced ( Fig. 20View Fig Ca); gonostylus in line with axis of gonocoxite ( Fig. 20View Fig Cc).

L. villosulum  : reflexed gonostylus lobe with apex more tapered, outer hind corner less produced; gonostylus directed inwards relative to axis of gonocoxite.

Also, in L. medinai  the bristles of the last sterna form a slightly thicker fringe ( Fig. 21View Fig).
