Mackay and Serna (2010) - The worker is a small (total length 2 mm) ferrugineous red specimen. The mandibles have seven teeth, the spiniform paraclypeal teeth on the clypeus are markedly well developed; the frontal lobes do not reach the inner borders of the eyes (frontal view of head). The frontovertexal comers form auricle-like structures; the scape is short, and does not reach the posterior margin of the scrobe. The mid pronotal process is angulate, the lateral pronotal tubercles are poorly developed. The anterior mesonotal tubercles are conical and posterior mesonotal tubercles approximately the same size. The propodeum is rounded posteriorly and without angles or spines. The subpetiolar tooth is well-developed and sharp, dorsally the petiole extends over the base of the anterior part of the postpetiole, which has two longitudinal elevated regions, the posterior margin of the postpetiole is nearly straight; the first opisthogastral tergum is without ridges or processes; all femora are swollen ventrally, with carinae, the posterior femur has a well-developed ventral lamina.
Erect hairs are sparse, present on the mandibles, apex of the scape, ventral surfaces of the legs, ventral and posterior surfaces of the gaster; appressed hairs are abundant on the dorsum of the first opisthogastral tergum.
All surfaces dull, except the region along base of mandibular teeth which is smooth and shiny.
Mycetophylax snellingi would key to Mycetophylax faunulus in Kempf's key (1964). It can be easily distinguished as the anterior mesonotal tubercle is relatively small, as compared to the greatly enlarged anterior mesonotal tubercle of M. faunulus. Additionally, the posterodorsal edge of the petiole of M. faunulus does not extend over the anterior face of the petiole as it does in M. snellingi. Mycetophylax faunulus also lacks the erect hairs on the frontal lobes. Although it would key to M. faunulus, the two species do not appear to be morphologically similar.

HL 0.71-0.74, HW 0.58, SL 0.48-0.50, EL 0.09-0.10, EW 0.08, WL 0.85-0.86. Indices: CI 78-81, SI 64-70, OI 82-86. Mandible with 7 teeth; spiniform paraclypeal teeth very well developed (length 0.07 mm), frontal carinae relatively narrowly spaced, not reaching preocular carina which forms mesiad margin of scrobe; eyes extending past sides of head, with about 20 ommatidia; scrobe greatly extending posteriorly, forming auricle-like structures; scapes not reaching posterior margin of scrobe; tubercles on pronotum poorly developed; anterior and posterior mesonotal tubercles moderately well developed and approximately same size, anterior tubercle with slighter broader base; dorsopropodeum shorter that posteropropodeum, propodeum without spines or angles; subpetiolar tooth sharp and well developed, petiole with two distinct, longitudinal lateral lobes, dorsum of posterior face extending over anterior part of postpetiole; postpetiole with longitudinal depressed region in dorsum of node, outlined by two elongated elevated areas; dorsal surface of gaster flat, bordered laterally by slightly elevated longitudinal areas; all femora with carinae along ventral posterior border, that on posterior femur more developed and forming lamina.
Few erect hairs on mandibles, anteclypeus and frontal lobes, remainder of hairs simple and appressed, located mostly on head and especially gaster.
All surfaces except mandiblular teeth and anterior edge of clypeus dull.
Named in honor of the memory of Roy Snelling, recalling a pleasant visit to the Los Angeles County Museum of Natural History in May of 2007 where we spent time with Roy, Gordon Snelling, Brian Brown, and Weiping Xie.
