Hysterosomatic margins straight, posteriorly rounded. Dorsal side (Fig. 1): Sensillus shaped like a plum-stone, Exobothridial hair extremely long (90 }x), interbothridial hair about twice longer than rostral seta. Hairs 03, e^, fj of hysterosoma considerably longer than the others, and approximately of equal length (100-110 ji). Hairs e

Posterior sternal plate also with some larger foveolae on both sides of sternum.

. Genu without incrassate hair. Femur of leg II (Fig. 3) with hair dF long, displaying 4-5 robust lateral cilia; hair ld"F thin, smooth, short. Tibia of leg IV (Fig. 4) with completely smooth and spiniform hair lv"T. Material examined: Holotype: N. Am. 1; 5 Ex. Paratypes (2 Ex.: T-1723-75: HNHM; 2 Ex..: USNM; 1 Ex.: MHNG, collected together with the holotype). Paratype: 1 Ex.: Figs. 1-4: Pygmephorus equitrichosus sp. n. 1: Dorsal side, 2: Ventral side, 3: Femur of leg II, 4: Leg IV. The various Pygmephorus species being very similar in appearance, only specific features will be referred to at the description of the dorsal side of individual species.
