Etymology: pygmaeus: The epithet pygmaeus, from the Latin pygmaei (singular pygmaeus), is an allusion to the very small or miniature size of Lacustricola pygmaeus, the smallest species within the L. hutereaui complex (Ref. 123968).

Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 10 - 12; Duri dubur: 0; Sirip dubur lunak: 12 - 15; vertebrata, bertulang belakang: 24 - 26. Diagnosis: Lacustricola pygmaeus is distinguished from L. centralis, L. jobaerti, L. johnstoni, L. jubbi, L. katangae, L. macrurus, L. matthesi, L. mediolateralis, L. moeruensis, L. myaposae, L. nigrolateralis, and L. stiassnyae by the possession of banded dorsal, anal, and caudal fins in males and also by the possession of a pointed premaxilla ascending process, in which the premaxilla medial surface is slightly convex (Ref. 123968). It is further distinguished from L. hutereaui, L. chobensis, and L. petnehazyi by an inconspicuous reticulate pattern on scale margins vs. conspicuous; banded anal, dorsal, and caudal fins in females vs. hyaline; faint bands in the middle rays of caudal fin of male vs. conspicuous bands; rounded caudal fin in males vs. elliptical; bright green-blue colour restricted to the area delimited by some of the flank scales vs. bright green colouration not restricted to scale area in L. chobensis and L. petnehazyi, and absent in L. hutereaui; quadrate posterior margin with a deep concavity vs. convex or about straight; first dorsal-fin ray inserted in a vertical to second and third anal-fin ray vs. fourth to eight (Ref. 123968). It is further distinguished from L. hutereaui by the absence of maxilla ventral sharp process vs. presence; retroarticular about the same size as anguloarticular ventral process vs. shorter; posteroventral extension on lachrymal vs. rectangular, without posteroventral extension; infraorbital canal anterior portion open, with three to four neuromasts vs. closed, with four pores; mandibular canal open, with two small neuromasts vs. closed, with four pores; head neuromasts placed in shallow grooves or on the same level as head surface vs. on deep grooves; possession of chromatophores close to eye, along infraorbital region vs. absence of chromatophores; posttemporal ventral arm not ossified vs. ossified; and by a cleithrum posterodorsal bone flap rounded vs. sinuous (Ref. 123968). Lacustricola pygmaeus is further distinguished from L. petnehazyi by the possession of 20-22 scales on longitudinal series vs. 24-27, and from L. chobensis by the possession of 26-30 caudal-fin rays vs. 21-24; 10-12 dorsal-fin rays vs. 6-8; and chromatophores along whole mid-body line of flank, forming an inconspicuous line vs. conspicuous (Ref. 123968).
