REMAINING (number with state)
Abdomen, T1-2, distance between pits in the longitudinal center of the tergites between the unpitted apical rim and the often often densely pitted basal area
 Pitting dense, averaging under one pit diameter, the difference in the pit density in the basal and middle areas being slight if there is any (8)
 Pitting sparse, averaging over one pit diameter and usually several, usually with a very significant difference in pit density between the basal and middle areas of T1-T2 (8)
 Pitting moderate, averaging about one pit diameter, usually with a noticeable difference in pit density between the basal and middle areas of T1-T2 (6)
Female, M. altadenae vs M. chaenactidis
 M. altadenae - Head is broader, the maximum length of the eye is greater than the distance BETWEEN the eyes across the width of the face measured when measured at the level of the antennal bases giving the a somewhat rectangular appearance - The pitting between the ocelli and antennal fossae is very dense such that most pits are spaced apart by half a pit diameter or less (1)
 M. chaenactidis - The face is roughly square, the maximum length of the eye is nearly equal to the width of the face between the compound eyes at the level of the antenmnal bases, giving the head an overall square shape - The pitting between the ocelli and antennal fossae is sparser, often with interpit spacing equal to or exceeding a full pit diameter in places (1)
Female, M. linsleyi vs M. mojavensis
 M. linsleyi - The area of the face between the antennal sockets and ocelli is marked by microscopic lines throughout, making this area appear somewhat dulled - The basal sculpting of the propodeal triangle, just posterior to the metanotum, is largely linear, forming striations running longitudinally from the base, and they DO NOT form a network of lines basally (1)
 M. mojavensis - The area of the face between the antennal sockets and ocelli is smooth and shiny between the dense pits - The basal sculpting of the propodeal triangle is at least somewhat reticulate, with the lines crossing each other and forming small cells, this most common near the base and sides although it sometimes continues throughout the entirety of the sculpted area (1)
Female, head, gena or cheek, interpit distances on the ventral area of the gena
 Sparse, interpit distance averaging more than one pit diameter, often several (6)
 Moderate, interpit distance averaging about one pit diameter (4)
 Dense, interpit distance averaging less than one pit diameter (2)
Flight Season - Month - This is for reference only and includes ONLY the known months of capture - All species are scored for ALL these months, but this information gives you an indication of which species might be captured in each month - Because this is an uncommon group it will not be definitive on its own
 3. III - March - M. ruficaudus (16)
 4. IV - April - M. chaenactidis, M. dinoceps, M. mojavensis, M. ruficaudus (16)
 5. V - May - M. altadenae, M. chaenactidis, M. dinoceps, M. grossus, M. mojavensis, M. ruficaudus (16)
 6. VI - June - M. dinoceps, M. grossus, M. linsleyi, M. quadriceps (16)
 7. VII - July - M. quadriceps (16)
Forewing, distance from the top of the 1st recurrent vein to the bottom of the 1st transcutibal vein
 Short, about 1-2 vein widths apart (14)
 Long, over 3 vein widths apart (8)
Head, the relation of length to width - Length measured from top of head to apex of clypeus - Width measured between the midpoints of the eye
 The width and length of the head are roughly equal or with the length slightly greater than the width, often difficult to tell if one is greater than the other (14)
 The width of the head greater than its length (8)
 CLEARLY AND OBVIOUSLY longer than wide, rectangular, usually about 1.5x as long as it is wide (2)
Locality where the bee was collected in California - Note that these distributions may be incomplete pending further sampling, use with caution
 Widespread throughout the central and southern coastal regions, although it should be noted that M. dinoceps is CURRENTLY ONLY known from the San Bernardino Mountains (10)
 In the Sierra Nevadas (6)
M. ruficaudus vs other species
 Other species - Although some reddening may be present on the tergites, it is usually only a DARK reddish color which suggests slight paling of the darker brownish to black integument - T2 is usually entirely or nearly entirely dark brownish or black - It should be noted that M. quadriceps sometimes displays paler integumental color, but this is most often more brown than reddish and the species may be distinguished easily by its very long, rectangular head shape (14)
 M. ruficaudus - The majority of the abdomen is a PALE reddish to orangish color, often with only parts of T1 and the lateral sides of the tergites and the tip of the abdomen appearing darker brownish or black - T2 usually with a blackish spot on each side near the lateral edge of the tergite, although in males T2 is often all reddish (2)
Male, M. grossus vs other species
 Other species - Although the hairiness of S6 is variable among the other species, the rim itself is relatively flat and unmodified near the middle of the rim - The lateral arms of S7 are variable in length, but the measurement from their base to apical tip is almost always greater than that of their base to the farthest lateral point (7)
 M. grossus - On the rim of S6 there is an integumental bump near the middle which is usually at least partially obscured by hairs that often take the form of a fan of sorts - The lateral arms of S7 are short and stout, with the distance from their bases to apices distinctly less than the distance from their base to their farthest lateral points (1)
Male, abdomen, S7, form of the interior arms found between the lateral arms - This character is often difficult to see, a dissection may be necessary for positive identification
 The interior arms are separated from their bases to their apices (6)
 The interior arms are touching within the apical halves of their lengths (3)
Male, abdomen, S7, orientation of the tips of the lateral arms - This character is often difficult to see, a dissection may be necessary for positive identification
 Curled inward in opposition, the tips essentially pointing at each other (5)
 Curled inward and forward, the tips bent around such that they point to the anterior of the bee (4)
Male, abdomen, S7, presence or absence of inward-facing projection about halfway along the lateral arms - This character is often difficult to see, a dissection may be necessary for positive identification
 Absent (6)
 Present (4)
Male, abdomen, S8, form of the medial projection on the rim - This character is often difficult to see, a dissection may be necessary for positive identification
 Rounded at the tip, with the sides of the projection wholly or almost entirely parallel in their length (6)
 Sharp, much wider at base than tip such that it appears pointed (3)
Male, thorax, propodeum, pattern of basal sculpting in the propodeal triangle - BE CAREFUL as any debris on the surface can be very problematic here
 Linear, with raised longitudinal lines or striations that remain roughly straight throughout their entirety, if with any reticulation then it is limited only to the basal fourth of the sculpted area (5)
 Weakly reticulate, with a series of raised intersecting lines which form a network that extends back about half the longitudinal length of the sculpted area (5)
 Strongly reticulate, with a network of cells throughout the entire sculpted area or nearly so (4)
Sex, number of antennal segments
 Female, 12 (8)
 Male, 13 (8)
State or province where bee was collected
 CA (16)
 AZ (2)
 NV (2)
